Uncovering the text of the New Testament

Cambridge University Library reached their appeal target after the National Heritage Memorial Fund recognised the importance of the Codex Zacynthius and stepped in with a grant of £500,000.

Such early manuscripts are extremely sought after as invaluable witnesses to the development of the text of the New Testament. The manuscript will now undergo multi-spectral imaging and XRF spectroscopy to enrich a new generation of research on the text.

Cambridge University Librarian Anne Jarvis said: “Since launching our appeal in December 2013, we have been delighted and humbled by the donations and support we’ve received.

“That support, especially from the National Heritage Memorial Fund, means that Codex Zacynthius can now take its rightful place among our world-renowned faith collections.”

Fiona Talbott, Head of NHMF, said: “The Codex Zacynthius has been part of the UK’s heritage for over 200 years and is a truly fascinating and unique object. Our trustees felt it was incredibly important that it should be safeguarded so future generations can explore its undiscovered secrets.”   

The huge appeal of this unique item lies in its hidden backstory. Codex Zacynthius is a palimpsest: a manuscript from which the text has been scraped or washed off in order for it to be used again. The recycling of manuscripts was common practice at a time when writing surfaces were precious, few books were produced, and a tiny percentage of the population was literate.

Codex Zacynthius is so-called because it resided on the Greek island of Zakynthos (also called Zante), although its original place of composition is unknown. Its 176 leaves are made of parchment – treated animal skin. The surface of the parchment was first used at the end of the 7th century when it was inscribed in Greek with the text of Luke 1:1–11:33 – a layer of writing now known to scholars as the ‘undertext’. In the 13th century this was partially scraped away and written over with the text of an Evangeliarium, a book composed of passages from the Four Gospels – this is the ‘overtext’.

Lord Williams of Oystermouth, the former Archbishop of Canterbury, who supported Cambridge’s fundraising campaign, said: “The discovery and identification of the undertext represents a fascinating detective story. By securing the manuscript, we hope that multispectral imaging techniques will enable scholars to recover fully the hidden text.”

Establishing the definitive text of the New Testament came late to Christianity and the Textus Receptus, produced by the great Dutch humanist scholar Erasmus (1469-1536), was for centuries the standard printed edition, despite its shortcomings. It was based on only six manuscripts and included parts of the book of Revelation that Erasmus had translated into Greek himself, from a Latin edition, since he didn’t have a complete manuscript of the Greek text.

Codex Zacynthius was deposited at Cambridge University Library in 1984 by the British and Foreign Bible Society, which has owned it for almost 200 years. The Bible Society wished to sell Codex Zacynthius as part of an exceptional exercise to release funds to establish a new visitor centre in Wales.

A £1.1m campaign by Cambridge University Library to secure one of the most important New Testament manuscripts – the seventh-century Codex Zacynthius – has been a success.

The new University of Cambridge Primary School is a three-form-entry fully inclusive primary school being established as part of the North West Cambridge Development. The first pupils will begin at the school in September 2015.

In addition to providing an inclusive and high-quality primary education for local children, the University of Cambridge Primary School will also offer unique training and research opportunities, through its close relationship with the Faculties and Departments of the University of Cambridge.

As the first Headteacher, James will play a key role in shaping the school’s character and vision. 

“Our curriculum intends to provide an holistic learning experience, informed by strong values which emphasise equality, compassion, courage, within a community in which everyone’s voice is welcome and valued,”  James said.

James hopes that strong, positive relationships will be found not only within the school but also between the school and the wider family of Cambridge primary schools, the Faculty of Education and the University as a whole.

James first realised that he wanted to teach as a career while travelling and working in Nepal. On his return to the UK he enrolled in the University of Cambridge’s PGCE course, attracted by its focus on creativity in professional practice.

Since graduation James has worked in several challenging schools in London, gaining Advanced Skills Teacher status in his second year of practice, and has become an experienced school leader.

“I applied for this role because I want to be part of a body of professionals eager to raise questions about what we do and how we do it, and finding the best ways through for every child by using our creativity,” James said.

“Our new school’s vision statement is to 'Release the Imagination: celebrating the art of the possible.' I am grateful to the Trust for giving me the opportunity to make that statement a reality, not only for our young people, but for teachers, parents and academics here in Cambridge, in the UK, and beyond.”
           
Professor John Rallison, the University’s Pro-Vice-Chancellor for Education and Chair of the Trust said: “It is a pleasure to welcome James to this exciting new role.

Gaia discovers its first supernova

$

0

This powerful event, now named Gaia14aaa, took place in a distant galaxy some 500 million light-years away, and was revealed via a sudden rise in the galaxy’s brightness between two Gaia observations separated by one month.

Gaia, which began its scientific work in July, repeatedly scans the entire sky, so that each of the roughly one billion stars in the final catalogue will be examined an average of 70 times over the next five years.

“This kind of repeated survey comes in handy for studying the changeable nature of the sky,” said Simon Hodgkin from the University of Cambridge’s Institute of Astronomy, who is part of Gaia’s Science Alert Team.

Many astronomical sources are variable: some exhibit a regular pattern, with a periodically rising and declining brightness, while others may undergo sudden and dramatic changes.

“As Gaia goes back to each patch of the sky over and over, we have a chance to spot thousands of ‘guest stars’ on the celestial tapestry,” said Hodgkin. “These transient sources can be signposts to some of the most powerful phenomena in the Universe, like this supernova.”

Gaia’s Science Alert Team includes astronomers from the Universities of Cambridge and Warsaw, who are combing through the scans in search of unexpected changes.

It did not take long until they found the first ‘anomaly’ in the form of a sudden spike in the light coming from a distant galaxy, detected on August 30th. The same galaxy appeared much dimmer when Gaia first looked at it just a month before.

“We immediately thought it might be a supernova, but needed more clues to back up our claim,” explains Łukasz Wyrzykowski from the Warsaw University Astronomical Observatory.

Other powerful cosmic events may resemble a supernova in a distant galaxy, such as outbursts caused by the mass-devouring supermassive black hole at the galaxy centre.

However, in Gaia14aaa, the position of the bright spot of light was slightly offset from the galaxy’s core, suggesting that it was unlikely to be related to a central black hole.

The astronomers looked for more information in the light of this new source. Besides recording the position and brightness of stars and galaxies, Gaia also splits their light to create a spectrum. In fact, Gaia uses two prisms spanning red and blue wavelength regions to produce a low-resolution spectrum that allows astronomers to seek signatures of the various chemical elements present in the source of that light.

“In the spectrum of this source, we could already see the presence of iron and other elements that are known to be found in supernovas,” said Nadejda Blagorodnova, a PhD student at the Institute of Astronomy.

In addition, the blue part of the spectrum appears significantly brighter than the red part, as expected in a supernova. And not just any supernova: the astronomers already suspected it might be a ‘Type Ia’ supernova – the explosion of a white dwarf locked in a binary system with a companion star.

While other types of supernovas are the explosive demises of massive stars, several times more massive than the Sun, Type Ia supernovas are the end product of their less massive counterparts.

Low-mass stars, with masses similar to the Sun’s, end their lives gently, puffing up their outer layers and leaving behind a compact white dwarf. Their high density means that white dwarfs can exert an intense gravitational pull on a nearby companion star, accreting mass from it until the white dwarf reaches a critical mass that then sparks a violent explosion.

To confirm the nature of this supernova, the astronomers complemented the Gaia data with more observations from the ground, using the Isaac Newton Telescope (INT) and the robotic Liverpool Telescope on La Palma, in the Canary Islands.

A high-resolution spectrum, obtained on September 3rd with the INT, confirmed not only that the explosion corresponds to a Type Ia supernova, but also provided an estimate of its distance. This proved that the supernova happened in the galaxy where it was observed.

“This is the first supernova in what we expect to be a long series of discoveries with Gaia,” said Dr Timo Prusti, ESA’s Gaia Project Scientist.

Supernovas are rare events: only a couple of these explosions happen every century in a typical galaxy. But they are not so rare over the whole sky, if we take into account the hundreds of billions of galaxies that populate the Universe.

Astronomers in the Science Alert Team are currently getting acquainted with the data, testing and optimising their detection software. In a few months, they expect Gaia to discover about three new supernovas every day.

In addition to supernovas, Gaia will discover thousands of transient sources of other kinds – stellar explosions on smaller scale than supernovas, flares from young stars coming to life, outbursts caused by black holes that disrupt and devour a nearby star, and possibly some entirely new phenomena never seen before.

“The sky is ablaze with peculiar sources of light, and we are looking forward to probing plenty of those with Gaia in the coming years,” said Prusti.

Simulation method identifies materials for better batteries

$

The researchers, from the Cavendish Laboratory and the Department of Chemistry, are devising new methods for understanding the complex interactions that take place within lithium-ion batteries, in order to identify and develop the best materials to make better batteries.

Using software to predict the characteristics of materials before they’re synthesised in order to guide and interpret experiments, the researchers successfully predicted the structures of a series of lithium silicides, an important step in understanding batteries made of silicon, and have also predicted new structures for a battery based on germanium. Details are published in the journal Physical Review B.

The lithium-ion battery market is large and growing rapidly. However, for many next-generation applications, such as longer-range electric vehicles and longer-lived consumer electronics, batteries which are smaller, more efficient and charge faster are needed.

Silicon has been proposed as a replacement for carbon in battery anodes, or positive electrodes, for the past 20 years. The anode must safely store lithium atoms when charged then release lithium ions, in turn causing electrons, which carry electrical current, to flow from the positive to the negative electrode. The more lithium the anode can store, the larger its capacity.

Most modern anodes are based on graphite, but silicon has roughly ten times the storage capacity, which in turn would greatly expand the capacity of the batteries used in mobile phones, electric vehicles and other applications. However, difficulty in managing silicon’s properties has prevented the technology from being applied at scale.

“It’s always exciting when we’re able to successfully predict something, but it’s especially gratifying to predict something that’s really useful,” said Dr Andrew Morris of the University’s Cavendish Laboratory, the paper’s lead author.

Lithium ion batteries are widely used due to their high energy density and high specific energy. They have a higher capacity than any other type of commercially-available battery, but in order to enable next-generation electronic devices, materials which can absorb, store and then release lithium quickly and safely need to be found.

More efficient batteries could potentially revolutionise a number of industries: for instance, enabling an electric car battery to be recharged in the same amount of time it currently takes to fill up a petrol tank, or allowing the energy generated by renewables to be stored for when it is most needed.

The various structures which the researchers predicted for lithium silicide have been shown to be stable in physical experiments, and further experiments are currently underway in Professor Clare Grey’s laboratory in the Department of Chemistry to determine whether the same is true for the structures they predicted for germanium and to determine the roles these structures play on battery cycling.

The arrangement of atoms in a material determines its properties – what it looks like, how hard or soft it is, or what electrical state has. Performing simulations in a computer is far more efficient than making new materials in a laboratory and performing physical experiments on them. “What happens in a battery is complicated, and we need to work out what the model compounds should be,” said Morris.

To perform their predictions, the researches used a method called AIRSS (Ab Initio Random Structure Searching), developed by one of the authors, Professor Chris Pickard of University College London, and Professor Richard Needs of the University’s Cavendish Laboratory. Starting with a random collection of atoms, AIRSS is able to predict the crystal structure of the materials they will form using only quantum mechanics.

The research was funded by the Winton Programme for the Physics of Sustainability and the Engineering and Physical Sciences Research Council (EPSRC).

Researchers from the University of Cambridge have devised a new simulation technique which reliably predicts the structure and behaviour of different materials, in order to accelerate the development of next-generation batteries for a wide range of applications.

The competition, made possible by a generous gift from Peter Baldwin and Lisbet Rausing, provided the perfect opportunity to elicit fresh and unconventional ideas for the landscape surrounding the Library; ideas which have the potential to transform not just the entrance sequence to the Library, but the way such open social spaces are being used.

Entries to this ideas competition were judged on their innovative interpretation of the site, its context, use and history – as well as their ability to integrate contemporary ecological research.

The eight shortlisted entries will be on display in the University Library Entrance Hall from September 12-28. Staff, students and members of the public are welcome to participate in the public vote as well as putting forward their own ideas on postcards provided in the Library.

Ingrid Schröder, from the Department of Architecture, said: “We were looking to prompt a true diversity of responses from the entrants – and that’s exactly what we have with the eight shortlisted entries. It was an ideas competition to visualise how the area surrounding Cambridge University Library could be reimagined. We haven’t been disappointed with the results.”

Advanced molecular 'sieves' could be used for carbon capture

$
0
0

Newly-developed synthetic membranes provide a greener and more energy-efficient method of separating gases, and can remove carbon dioxide and other greenhouse gases from the atmosphere, potentially reducing the cost of capturing carbon dioxide significantly.

The synthetic membranes, made of materials known as polymers of intrinsic microporosity (PIMs), mimic the hourglass-shaped protein channels found in biological membranes in cells. The tiny openings in these molecular ‘sieves’ – just a few billionths of a metre in size – can be adjusted so that only certain molecules can pass through. Details are published in the journal Nature Communications.

Current methods for separating gases are complex, expensive and energy-intensive. Additionally, conventional polymers, while reliable and inexpensive, are not suitable for large scale applications, as there is a trade-off between low permeability levels and a high degree of selective molecular separation.

Researchers are attempting to develop new methods of energy-efficient and environmental-friendly membrane-separation technology, which is an essential process in everything from water purification to controlling gas emissions.

The team from the University’s Cavendish Laboratory, working with researchers from Kyoto University, has developed an alternative approach to generating polymer membranes, ‘baking’ them in the presence of oxygen, a process known as thermal oxidation.

Inducing a thermal oxidation reaction in the PIMs causes the loosely-packed long chains of polymer molecules to form into a cross-linked network structure, with hourglass-shaped cavities throughout. This structure not only results in a membrane which is more selective to gas molecules, but also the size of necks and cavities can be tuned according to what temperature the PIMs are ‘baked’ at.

“The secret is that we introduce stronger forces between polymer chains,” said Dr Qilei Song of the Cavendish Laboratory, the paper’s lead author. “Heating microporous polymers using low levels of oxygen produces a tougher and far more selective membrane which is still relatively flexible, with a gas permeability that is 100 to 1,000 times higher than conventional polymer membranes.”

The cross-linked structure also makes these membranes more stable than conventional solution-processed PIMs, which have a twisted and rigid structure - like dried pasta - that makes them unable to pack efficiently. Thermal oxidation and crosslinking reinforces the strength of channels while controlling the size of the openings leading into the cavities, which allows for higher selectivity.

The new membrane is twice as selective for separation carbon dioxide as conventional polymer membranes, but allows carbon dioxide to pass through it a few hundred times faster. These thermally modified PIMs membranes are among molecular sieves with the highest combinations of gas permeability and selectivity. In addition to possible uses for separating carbon dioxide from flue gas emitted from coal-fired power plants, the membranes could also be used in air separation, natural gas processing, hydrogen gas production, or could help make more efficient combustion of fossil fuels and power generation with much lower emissions of air pollutants.

“Basically, we developed a method for making a polymer that can truly contribute to a sustainable environment,” said Professor Easan Sivaniah from Kyoto University's Institute for Integrated Cell-Material Sciences (iCeMS).

“This new way of modifying PIMs brings the prospect of large-scale, energy-efficient gas separation a step closer,” said Professor Peter Budd, from the University of Manchester, one of the inventors of PIMs materials.

This research was supported by the Engineering and Physical Sciences Research Council (EPSRC) and the European Research Council (ERC).

Researchers from the University of Cambridge have developed advanced molecular ‘sieves’ which could be used to filter carbon dioxide and other greenhouse gases from the atmosphere.

Good vibrations for Forth Road Bridge

$
0
0

A team from the Cambridge Centre for Smart Infrastructure and Construction (CSIC) have designed vibration energy harvesters which convert ambient vibrations into electricity, eliminating the need for batteries and making remote monitoring of the long-span suspension bridge’s health much easier. A trial deployment of the harvesters will take place early next year.

The 2.5 kilometre-long Forth Road Bridge, which connects Edinburgh and Fife, now carries far more traffic than it was originally designed for. About 25 million vehicles now cross the bridge each year, nearly ten times the number it carried when it opened in 1964.

The increased  strain that the additional traffic load has had on the structure became apparent during a routine inspection of the bridge’s cables in 2004, when extensive corrosion was discovered in the strands making up the main suspension cables.

After the damage was identified, the decision was made to build a new road bridge alongside the Forth Road Bridge and Forth Rail Bridge. The Queensferry Crossing is due to open in 2016, and traffic on the Forth Road Bridge will then be limited to buses, taxis, cyclists and pedestrians. Although traffic load will be reduced significantly when the new bridge opens, there will still be a requirement for ongoing monitoring of the older structure.

Professor Campbell Middleton and a CSIC bridges team believe the work they are undertaking to develop and demonstrate wireless sensor network (WSN) technology may have a role to play in monitoring various key structural elements on the bridge. However, one of the problems holding back the adoption of WSN, particularly in difficult-to-reach areas like underneath a busy bridge, is the need to change batteries on a regular basis. The issue is not the cost of the batteries themselves, but rather the cost of the human power to replace the batteries.

In a bid to solve this issue, Dr Yu Jia and Dr Ashwin Seshia have developed a new vibration energy harvester based on a phenomenon known as parametric resonance, which amplifies vibrations. The device has the potential to harvest significantly more energy from ambient vibrations than previous designs, and vibration data collected from the Forth Road Bridge during a field investigation is now being used by Dr Jia to optimise the harvester for a trial deployment at this Scottish landmark early next year.

“As vibration energy harvesting improves and the amount of energy available to power sensors increases, new radio technologies are emerging with lower power requirements,” said Professor Middleton. “We may be approaching the point at which a vibration powered wireless sensor network, with no need to change batteries, becomes a reality. This would be a world first.”

The low cost, wireless, battery-free sensors will enable CSIC to measure the behaviour of key structural elements on this critical piece of infrastructure, giving its owners a far greater understanding of the actual capacity and level of safety of the bridge.

Professor Middleton continued: “The Forth Road Bridge offers a fantastic opportunity to test this innovative technology which will provide key information to the bridge owners and managers, leading to knowledge and reassurance of its on-going safety performance, which could see the Forth Road Bridge surviving a further 50 years or more.”

As celebrations marking the 50th anniversary of the opening of the Forth Road Bridge take place this month, a team of Cambridge engineers are preparing to deploy state-of-the-art self-powered wireless sensors which could help monitor and protect the Scottish landmark well into the future.

Fancy pants: skirmishes with the fashion police in 16th-century Italy

$
0
0

On 15 September 1595, a Genoese man-about-town called Salvagio de Aste was spotted breaking the law. The record in Genoa's state archives describes with remarkable precision what Salvagio was wearing that autumn day as he strolled through the square of San Siro. He must have cut a dashing figure. He sported “an embroidered cap, a silk doublet of many colours with gold buttons on the sleeves, two rings with white stones on his fingers, a jerkin and embroidered hose in black silk”.

The detail with which Salvagio’s attire was noted is no accident: his showy and costly clothing was his crime. His colourful and lavishly embellished costume had fallen foul of Genoa’s Magistrato delle Pompe, whose role it was to enforce the sumptuary laws that regulated what men and women could wear. Patrolling the streets and squares of the bustling city as arbiters of the level of ostentation that was deemed appropriate, the sumptuary magistrates were quite simply the Fashion Police.

The role of these magistrates, and their (largely unsuccessful) attempts to moderate excessive spending, is one strand of research into clothing in early modern Genoa by Giulia Galastro, a PhD candidate in the History Faculty at Cambridge University. In particular, she is interested in the ways in which the materiality of fabric is interwoven with the fabric of society in Genoa – a centre of the Italian silk trade and a city famous for its production of sumptuous velvets and other luxurious textiles. 

Sumptuary laws restricted the use of precisely these textiles, along with expensive decoration such as embroidery with gold and silver thread. It also covered jewellery and ostentatious modes of transport, such as the lady in a litter seen in this image taken from a travelogue (owned by Strahov Monastery) of a Bohemian nobleman, who visited Genoa at the beginning of the 17th century.

Italy wasn’t alone in having sumptuary laws – the obsession with legislating against costly clothes spread across Europe during the Middle Ages. In England, James VI and I abolished sumptuary laws in 1604 but continued to control dress by other means. “The purpose of the laws is a matter of some debate. Their wording suggests concern that luxury goods could damage the morals of those who consumed them. Fashion itself was seen as immoral: its transitory nature stoked an acquisitive lust for new goods,” said Galastro. 

Financial considerations were also at play. A 15th-century Genoese law bemoaned "a great quantity of money which is kept dead and wrapped up in clothing and jewels, [and] if converted into trade might bring great return and profits". Some scholars, such as the historian Jane Bridgeman, have argued that the laws were an indirect tax on wealth, working on the tacit assumption that the rich would be prepared to pay to get around them.

“Part of the problem is that not much evidence for how the laws were enforced has been preserved, so it’s difficult to know how – and whether – they worked in practice. That’s what makes the Genoese sumptuary records so special. The rare survival of notes kept by the sumptuary magistrates gives us a glimpse of the laws in action, and of clothes in use. We can begin to build up a picture of who was wearing what, when and where,” said Galastro.

The records suggest that residents of Genoa routinely ignored the sumptuary laws. In the four years from 1594 to 1598, the magistrates recorded more than 560 contraventions of the regulations. The foppish Salvagio was among the repeat offenders. Three days after being admonished on 15 September 1595 he was back in San Siro, wearing exactly the same outfit. On 5 November he was there again, wearing a leather jerkin impregnated with musk.

The sumptuary magistrates were caught up in a game of catch-me-if-you-can as Genoa’s dandies defied and subverted the rules. The feckless Salvagio broke the law at least a further four times, suggesting that whatever fine was imposed was no deterrent to a man determined to strut his stuff. 

“It is likely that any fines imposed were modest in comparison with the cost of the offending garments. A whole outfit in silk velvet, embroidered with precious metal threads, could come close to the price of a sports car today: if you could afford to buy the clothes, you could afford to pay the fine – or the bribe,’ said Galastro.

In analysing the records of the Genoese sumptuary laws, Galastro made a startling discovery. She said: “Contrary to widely held beliefs, male offenders outnumber females. In terms of overall sumptuary offences, there are 289 men to 242 women. If we focus on offences concerning dress, however, the disparity is more striking: 269 men to 99 women. In other words, there were almost three times as many men breaking the law on clothing as women.” 

Historians have often presumed that, where sumptuary laws mention men at all, it is for dressing too femininely, but Galastro’s research suggests something different.

“It’s interesting that the majority of the offences relate to an outfit of black silk - taffeta, satin or velvet - ornamented with some sort of precious metal stitching or with lace. Just such an outfit appears in a portrait of an anonymous Genoese nobleman by the artist van Dyck which, to modern eyes, looks relatively sober. But black was a clear status symbol in Renaissance culture. Black dye was one of the most difficult to fix effectively, so we should be careful how we interpret these apparently ‘plain’ portraits,” said Galastro.

Anthony van Dyck worked in Genoa for six years from 1621 and painted a series of exquisite portraits of the local aristocracy. These show the city’s elite wearing exquisite garments. He moved to London in 1632 where his portraits such as ‘Lord John Stuart and his brother Lord Bernard Stuart’, circa 1638, show men wearing much more colourful and flamboyant clothing.

Clothes are made to be worn and the wearing of them is a form of performance – seldom more so than on the streets of a fashionable Mediterranean city humming with life. “If you pair the sumptuary records with literary sources, it seems that what was disquieting to the sumptuary magistrates in Genoa was a particular form of vaunting, flaunting masculine dress,” said Galastro.

In his 1620 commentary on the Characters of Theophrastus, the Genoese writer Ansaldo Ceba describes the effrontery of the young man who will “when he is wearing breeches alla Spagnola, or an embroidered doublet, circulate around the city so sedulously that you can’t help bumping into him in church, in the square, or on the corner… You needn’t think of leaving until you have admired him from head to toe. Indeed he will compel you to do so, now by opening his cloak, now by planting himself in front of you like a bulwark”. 

Infringements of the sumptuary laws weren’t confined to the elite: artisans too were under scrutiny. Some were caught by the sumptuary magistrates while making luxury clothes. On 20 May 1595, the wife of Gioannetino the cheese-maker was spotted sitting on her doorstep sewing a man’s silk shirt, dyed in costly crimson, with gold and silver braids three fingers’ thick. Later in the summer three tailors were also caught working on luxury items. 

These artisans were caught in a dilemma: their livelihoods depended on making luxury goods. “It is estimated that some 60% of the Genoese population was involved in the production of textiles and clothing – from the women employed to unwind silk filament from cocoons through the dyers and weavers in their workshops to the hundreds of tailors and seamstresses,” said Galastro.

It was an era when people had a hands-on relationship with textiles, choosing and purchasing fabrics in consultation with their tailors with the arrival of new textiles and trimmings eagerly awaited. The vocabulary of fabrics and fashion was fabulously diverse – colours such as ‘incarnadine’ (the red of raw flesh) – most of these words lost to us today.

“What you wore, and how you wore it, was a matter of deep significance,” said Galastro.

With the autumn 2014 fashion shows in full swing, all eyes are on the top designers. In 16th-century Italy, the latest looks didn't always go down well with the authorities. Historian Giulia Galastro is researching the sumptuary laws regulating the level of opulence that could be paraded in public – and how the dandies of the day neatly side-stepped the rules.  

The purpose of the laws is a matter of debate. Their wording suggests that luxury goods could damage the morals of those who consumed them. Fashion was seen as immoral: its transitory nature stoked an acquisitive lust for new goods.

Study offers clues to how breast implants may cause lymphoma

$

There have been 71 known cases worldwide of a type of blood cancer called anaplastic large cell lymphoma (ALCL) that the researchers suggest were associated with the patient's breast implants. This means it is an extremely rare occurrence – for every three million breast implant procedures, the study estimates between one and six cases of ALCL. The ALCL was found to develop in patients, on average, 10 years after breast augmentation or reconstruction surgery. Studies have found no clear evidence of an increase in risk of any other type of cancer in women with breast implants. 

ALCL typically appears in the lymph nodes, skin, lungs, liver and soft tissue. It almost only ever occurs in the breast area if the patient has had breast implants and, in these cases, the tumours always develop in the scar tissue around the implant capsule. The exact reasons why implants could possibly contribute to lymphoma have remained unclear, however.

Researchers, funded by the blood cancer charity Leukaemia & Lymphoma Research, examined case reports from patients and analysed medical literature. The findings are published in the journal Mutation Research. 

ALCL patients are normally sub-divided into two groups – those with cancer cells that express an abnormal protein called anaplastic lymphoma kinase (ALK) inside the cell and those with cancer cells without the ALK protein. While eight in 10 patients with ALK-positive lymphoma survive for five years or more, ALK-negative lymphoma patients generally need more aggressive treatment and just under half survive beyond five years.

The researchers argue that implant-related ALCL, if backed by more research, should be treated as a separate clinical entity to other types of ALCL, owing to its distinctive biological characteristics. Almost all patients diagnosed with implant-related ALCL were ALK-negative and yet most actually had a very good prognosis. Of the 49 cases where information on the patients’ progress was available, there were only five reported deaths.

While some patients received chemotherapy and radiotherapy, for many women their lymphoma was put into remission simply through removal of the breast implant and surrounding tissue. This suggests that it is the body’s abnormal immune response to the implant that is causing the cancer. Chemotherapy was not shown to significantly increase survival in patients.

There is some evidence to suggest that simply having a prosthetic implant can increase risk as opposed to anything connected with the breast implant material, as patients with hip or knee replacements may also have a very small increased chance of developing lymphoma. Others have proposed that it is differences in lifestyles of people with and without breast implants that could be responsible. The Cambridge scientists, however, argue that the biological features of lymphomas in the presence of implants, such as the lack of ALK and the proximity to the implant, suggest a real link.

Dr Suzanne Turner, who led the research at the University of Cambridge, said, “It’s becoming clear that implant-related ALCL is a distinct clinical entity in itself. There are still unanswered questions and only by getting to the bottom of this very rare disease will we be able to find alternative ways to treat it.”

Dr Matt Kaiser, Head of Research at Leukaemia & Lymphoma Research, said: “It’s important to remember that any breast implant-associated lymphoma is incredibly rare. It is, however, important to investigate any possible links to what causes these cancers, so that we can help people balance benefits versus risks and so that we can work out how we might be able to prevent the risks altogether.”

Researchers at the University of Cambridge, together with colleagues specialising in plastic surgery or histopathology in Austria, Australia, Liverpool and Swansea, have identified clues to explain how breast implants may, on very rare occasions, contribute to the development of lymphoma.

Time to solve the Scottish innovation problem

$
0
0

They are the “vital six per cent”: high growth firms, both new entrepreneurial ventures and established companies, which play a critical role in successful economies. These are the firms that drive gains in productivity, national competitiveness, and ultimately living standards.

But Scotland just doesn’t have enough of them. The country has a long history of innovation and a proud tradition of making and building things – it was at the forefront of science, engineering and commerce during the Industrial Revolution after all – but in recent years, Scotland’s innovation performance has been less distinguished.

Not enough of its companies are truly global in scale and its “business base” – the number of firms per head of population – is relatively small. Moreover, survey data indicate that Scottish entrepreneurs tend to be less internationally oriented, and their ambitions for growth are markedly below the average of entrepreneurs in the UK as a whole. The upshot, as noted in a recent report by MIT’s Regional Entrepreneurship Acceleration Program, is that Scotland “is not meeting its potential in delivering high-growth businesses“.

The role of government
Scotland’s future economic prosperity, inside or outside of the union, depends on its ability to address this problem: it needs to nurture more high growth ventures if the country is to close the gap in income and living standards with the most economically successful nations. But what effect would separation have on entrepreneurship and innovation in Scotland?

There is increasing recognition that Scotland’s, and indeed the UK’s, tepid innovation performance is rooted in part in successive UK governments’ misunderstanding of the role of the state in driving entrepreneurship and high growth firms. In years gone by, the UK had an “industrial policy” in which government played a key role in shaping national economic priorities.

Such an approach to managing the economy has become decidedly unfashionable, intimately associated in the minds of many with the apparent waste and under-performance of the post war period. Indeed, since the 1980s the UK government has played a limited role by international standards in shaping innovation outcomes. This is evidenced, for example, by its anaemic investment in research and development – 18th in the world on a per capita basis.

The folly of such an approach is articulated powerfully in Mariana Mazzucato’s recent book on The Entrepreneurial State. Through detailed analysis of a range of technologies and industries she shows how bold investments by governments drive entrepreneurship in many of the most important economic sectors. This is particularly apparent in the USA, the most innovative country in the world, where the state “has been engaged on a massive scale in entrepreneurial risk taking to spur innovation”.

Meanwhile, UK policy makers continue to adhere slavishly to the dogma that innovation is most effective when private sector led, and that intervention by the state retards rather than supports wealth creation. A radical change of direction in UK innovation policy seems unlikely, certainly under the present coalition: current attempts to build an innovation strategy, and to “re-balance” economic activity away from London and the South East, are unconvincing and the resources allocated simply inadequate.

The impact of independence
So might an independent Scotland build a more interventionist policy infrastructure that promotes entrepreneurship and supports innovative firms? The rhetoric of the Scottish government, which advocates a “growth sectors approach” to economic development, certainly suggests so. It claims “Independence would provide much greater opportunities to promote business growth and to shape the long-term development of Scotland’s business base in a manner which delivers greater stability and supports re-industrialisation.”

Yet, as far as I can tell, there are no concrete policy proposals or overarching vision for fulfilling this aspiration. Indeed, the Scottish government’s recent policy document – Scotland Can Do: Becoming a World Leading Entrepreneurial and Innovative Nation – is essentially without content: a series of superficial case studies and cherry picked claims about entrepreneurship in Scotland. It inspires little confidence that a future SNP-led administration would be able to be able to deliver on its economic objectives post independence.

Like so many of the key issues at the heart of the independence debate, then, the prospects for entrepreneurship and innovation in a separate Scotland are uncertain. On the one hand, there is lingering dissatisfaction with the status quo among many Scots and a sense that their country is falling short of its economic potential within the union. On the other hand, nationalists offer a utopian economic vision for Scotland post-independence, but no intellectually coherent strategy or policy architecture for how this can be achieved.

With such paucity of ambition on both sides, it is little wonder many Scots are struggling to make up their minds about how to vote in the impending referendum.

A lack of innovation is starting to put Scotland’s economic prosperity – in or out of the union – at risk. Professor Paul Tracey argues it’s time for entrepreneurs to step up to the plate.

Curating Cambridge: Kettle's Yard autumn season

$

0

Past, Present, Somewhere: Films and Projects by Karen Guthrie & Nina Pope (13 September – 23 November 2014) is a rare opportunity to enjoy the collected films and projects by the artist duo, in their first gallery show since their winning installation for the Northern Art Prize in 2008.

Founding their collaborative entity Somewhere in the mid-nineties, Guthrie and Pope have long challenged the proscribed boundaries of the art world, creating idiosyncratic films and diverse participatory projects that range from interactive online worlds to a vast community-built ‘model village’ made from cob (an ancient earth building technique). This last piece was the result of their most recent commission Tomorrow, Today for the University’s North West Cambridge Development.

What runs through Guthrie and Pope’s fifteen years of work is a fascination with history and with place, and with how we make ourselves at home in the world by making both our own. Perhaps inevitably for a working partnership, their work is full of dichotomies skilfully and wittily explored - an early devotion to the Internet coupled with a love of craft; insightful self-portaiture and autobiography interwoven with grand communal histories; a delight in the domestic and the super- local balanced with a fascination for other cultures and countries.

Their acclaimed documentary films shine a light on often marginalised or unknown communities. A dedicated cinema room focuses on a presentation of three of their most important feature-length films, including Jaywick Escapes, the portrait of a deprived and long-forgotten Essex seaside town and its prospectless inhabitants.

As part of an extended programme of talks and events relating to Guthrie and Pope's wide-ranging and significant practice there will be a special screening of their newest film The Closer We Get.

This exhibition and associated events are part of Curating Cambridge, the University of Cambridge Museums city-wide festival.

Gwen Raverat: Wood Engravings
13 September - 23 November 2014, in the House at Kettle’s Yard

In Helen Ede’s bedroom a series of wood engravings by Gwen Raverat (1885-1957) will be on display. Most famous as the author of ‘Period Piece – a Cambridge Childhood’  Raverat also played a significant part in the wood engraving revival in Britain at the beginning of the 20th Century.

Thanks to the Raverat Archive and the Fitzwilliam Museum for their assistance with this exhibition.

Issam Kourbaj: New Installation
13 September - 26 October 2014, in St Peter’s Church

Born in Syria, Kourbaj has lived in Cambridge since 1989 and has been artist in residence at Christ’s College for many years. This recent work is informed by current events in his native Syria. In ‘Unearthed (In Memoriam)’ old hardback book covers are placed side by side covering much of the church floor, some covers are painted with white or coloured paint others have a black line painted across them, a representation of the ribbons placed over the photographs of the recently deceased in Syria.

Supported by the Churches Conservation Trust.

I Come from a Place: Katherine Green and North Cambridge Girls Group
18 October - 26 October 2014

Social documentary photographer Katherine Green and the ‘Club United’ group of teenage girls from North Cambridge have been photographing their community and experiences. At the same time, Katherine Green has been interviewing and taking portraits of some of the long term residents and community leaders from the area. The resulting exhibition celebrates this vibrant and welcoming part of the city.

Supported by Cambridge City Council.

This autumn Kettle’s Yard hosts four varied and inspiring exhibitions  - Nina Pope & Karen Guthrie take over the main gallery with the first major survey of their work, Issam Kourbaj installs his moving piece Unearthed (In Memoriam) in St Peter's Church next to Kettle's Yard, Gwen Raverat's wood engravings are on display in a room in the house, and for one week only an exhibition of photographs by Katherine Green and the North Cambridge Girls Group takes place in the Learning Studio.

Together we strive, alongside people we meet, to piece together the past and make a stab at the future. Most importantly we spend time now, in the moment, struggling with the stuff of ‘Somewhere’ and trying to record what this can look like.

in "Beyond Cambridge - Spotlight on Careers" five recent graduates talk about their experiences at Cambridge and how their time at university is helping them in their current roles with employers from Innocent Drinks and the National Trust to the BBC. The film also highlights post-graduate study as a career choice. 

The academically-demanding degree courses, opportunities to get involved with clubs and societies, and the support of the University Careers Service, mean that Cambridge graduates are highly sought-after on the job market.

“Cambridge is an eclectic melting pot of interesting people,” said Dan, now working as a Logistics Specialist at Innocent. “The knowledge gleaned, the friends acquired and the lessons learnt in my time at Cambridge make it, in my opinion, something worth striving for."

Maths graduate Natasha is now working as a Software Developer in the banking sector. “I think one of the best things I got out of Cambridge was the supervision system,” Natasha said, reflecting on the University’s famous small-group teaching.

“The confidence that gives you, you’re presenting your work, getting feedback on it – in technology that’s so useful, because you get reviewed by your peers all the time, and that can be tough, it feels like criticism. But supervisions really taught me how to take that criticism, and counter it if it feels appropriate, and how to represent myself in that situation.”

“We offer a very personalised service,” explains Gordon Chesterman, Director of the University Careers Service. “We serve all students, all Colleges, all degrees and all career interests.

“Employers and students should meet each other early - during the first year or early in their second year of studies,” Gordon advises.

“Attractive placement opportunities are now being offered for these early birds and this film will help remind newly-arrived students to engage with their Careers Service early on.

“Students need not have a clear job focus – few do – but we’ll help identify and explore assorted ideas for a possible career, help them meet potential employers and offer our full support in making a successful application.

“We encourage students to explore and investigate a whole variety of options before settling on two or three areas that they really want to focus in on.”

Jess Bond, who co-ordinated the project for the University, said “Cambridge graduates of all disciplines are highly employable, and we have one of the highest proportions of graduates entering graduate-level employment or further study in the country.  We hope that this film will inspire and motivate current and prospective students to make the most of what the University has to offer."

A new film from the University of Cambridge  highlights the broad range of careers which the university’s graduates go on to enjoy.

Global violence rates could be halved in just 30 years, say leading experts

$

0

The University of Cambridge and the World Health Organisation (WHO) have brought together 150 of the world’s foremost scientists and criminologists to set out the first roadmap for reducing global rates of interpersonal violence - a problem that now causes more death and costs more money than all wars combined.

New evidence will be presented at the first Global Violence Reduction Conference in Cambridge today which shows that homicide rates have been declining since the mid-1990s in many parts of the world - in some cases dramatically.

Nations as diverse as Estonia, Hong Kong, South Africa, Poland, and Russia have seen average recorded homicide rates drop by 40% or more in the course of just 15 years. Out of 88 countries where trend data could be found, 67 showed a decline and only 21 showed an increase between 1995 and 2010, a new analysis of data from the United Nations Office on Drugs and Crime has revealed.

The findings are part of an emerging body of evidence - from research into effective policing strategies, rehabilitation methods, better child protection services, and societal attitude shifts - which has many experts agreeing that global rates of violence could be halved by just 2040 if the right policies can be defined and implemented.

International support is growing, with the World Health Assembly issuing a resolution for an action plan on interpersonal violence in May this year. Those gathered in Cambridge call on governments and other stakeholders to lobby for violence prevention and reduction to become a concrete part of the UN’s post-2015 development agenda.

“Examples of successful homicide reduction over the past 15 years can be found across the world: from Canada and Italy to New Zealand and China. But if we want to achieve a worldwide decline in homicide we need to learn from these success stories and understand what they did right,” said Prof Manuel Eisner, conference co-convener and director of Cambridge’s Centre for Violence Research.

“Evidence from many places in the world suggests reductions in violence by about 2.3% per year - needed for a 50% drop in 30 years - are feasible and realistic.”

Eisner emphasises that this is not a yet global decline; some countries - primarily Latin American - have seen recent increases in homicide which may offset the overall picture, and little is known about trends in much of Africa. But many European, Northern American and Asian countries are showing a steep decline in homicide over the past two decades, and the lessons from these nations need to be built upon.   

Eisner’s analysis shows that homicide fell in societies that combined improved governance with effective policing strategies, a tighter net of control including surveillance technologies, and a lower tolerance for violent and disruptive behaviour from an earlier age.

The problem of interpersonal violence can seem insurmountable. In the 21st century, homicide has a higher body count than all wars combined - some 8 million people since 2000. Around 30% of women have experienced domestic violence; one in seven children on the planet is thought to be a victim of sexual abuse. Recent research commissioned by the Copenhagen Consensus Centre estimated that domestic violence costs the world $8 trillion annually (more than war).

But many experts feel there is cause for optimism. Interpersonal violence has been steadily declining for hundreds of years; a decline that has become particularly sharp in many societies over the past few decades:

“In London, the risk of being murdered has declined by a staggering 99% from the late Middle Ages to the present day. In the last ten years alone, the number of homicides in London has been cut in half, from around 200 in 2003 to less than 100 in 2013, for example - making it one of the safest cities in the world,” said Eisner.


Changes in homicide rates between 1995 - 2010.

Significant challenges are faced in developing countries, and more research on effective violence reduction needs to be focused on these societies. Almost half (45%) of all homicides worldwide are committed in just 23 countries where only 10% of the world population lives.  However, only 5% of all evaluations of effective violence prevention have been conducted outside wealthy western societies.

The causes of violence extend to the institutional backbone of many of these countries. Analysis shows that societies with the highest murder rates in Latin America, Africa and Asia – such as El Salvador, Congo and Russia – suffer from a mix of corruption, highly profitable illegal markets, low investment in public health and education, and an ineffective police force that is not trusted by the citizens.

“Making the state more legitimate in the eyes of its citizens, the police more effective and accountable, and promoting the rule of law will be critical to achieve a significant decline of violence,” Eisner said.

Global step-changes are required in the way societies are policed and new technologies are used to prevent violence, say the experts. Currently only 20% of the world’s populations live in societies that gather evidence to support better policing; this should increase to 60% by 2044.

“An accountable and effective police that are trusted by civil society is indispensable,” said Prof Lawrence Sherman, Director of Cambridge’s Institute of Criminology. Sherman, an authority in ‘crime experiments’, points to a recent example of the role such work could play in violence reduction: an experiment he conducted in Trinidad showed a GPS-mapping strategy for police patrols caused a 41% reduction in murders and shootings.

Most experts agree that violence prevention needs to start earlier in life. Parenting support systems, child protection measures and evidence-based early social skills training hardly exist in areas most affected by child abuse and domestic violence. “We are beginning to see more initiatives in poor countries, where academics, governments and stake-holders find ways to disseminate prevention strategies found to be effective in rich countries,” said the conference organisers.

The joint WHO/Cambridge conference will feature latest evidence from a truly global range of reduction research - from Sao Paulo street gangs to civil conflict in sub-Saharan Africa - and create vital links between violence researchers worldwide with the aim of placing violence reduction on the international agenda.

The WHO’s first status report on global violence prevention will be launched this winter, providing a solid information base of where countries stand in prevention efforts, and where the major gaps lie. “This offers an unprecedented opportunity for violence prevention stakeholders to come together and step up their activities,” said Alex Butchart, conference co-convener from the WHO.

Eisner calls on governments to develop their own national action plans to reduce violence, and to this end his team will be working closely with the WHO and researchers from every continent to create a series of policy recommendations.

The conference, supported by the UBS Optimus Foundation, will close with a speech from one of the world’s pre-eminent writers and thinkers: Steven Pinker, Professor of Psychology at Harvard University, whose best-selling book The Better Angels of our Nature (2011) draws upon research by Eisner and others to explore the decline in violence.

Research shows that homicide rates in many countries are falling; leading experts from around the world believe that global rates of homicide and other interpersonal violence - such as child abuse and domestic violence - could be reduced by as much as 50% in just 30 years if governments implement the right policies.

Stem cells use “first aid kits” to repair damage

$
0
0

Stem cells hold great promise as a means of repairing cells in conditions such as multiple sclerosis, stroke or injuries of the spinal cord because they have the ability to develop into almost any cell type. Now, new research shows that stem cell therapy can also work through a mechanism other than cell replacement.

In a study published today in Molecular Cell, a team of researchers led by the University of Cambridge has shown that stem cells “communicate” with cells by transferring molecules via fluid filled bags called vesicles, helping other cells to modify the damaging immune response around them.

Although scientists have speculated that stem cells might act rather like drugs – in sensing signals, moving to specific areas of the body and executing complex reactions – this is the first time that a molecular mechanism for this process has been demonstrated. By understanding this process better, researchers can identify ways of maximising the efficiency of stem-cell-based therapies.

Dr Stefano Pluchino from the Wellcome Trust-Medical Research Council Cambridge Stem Cell Institute, who led the study, said: “These tiny vesicles in stem cells contain molecules like proteins and nucleic acids that stimulate the target cells and help them to survive – they act like mini “first aid kits”.

“Essentially, they mirror how the stem cells respond to an inflammatory environment like that seen during complex neural injuries and diseases, and they pass this ability on to the target cells. We think this helps injured brain cells to repair themselves.”

Mice with damage to brain cells – such as the damage seen in multiple sclerosis – show a remarkable level of recovery when neural stem/precursor cells (NPCs) are  injected into their circulatory system. It has been suggested that this happens because the NPCs discharge molecules that regulate the immune system and that ultimately reduce tissue damage or enhance tissue repair. 

The team of researchers from the UK, Australia, Italy, China and Spain has now shown that NPCs make vesicles when they are in the vicinity of an immune response, and especially in response to a small protein, or cytokine, called Interferon-g which is released by immune cells. This protein has the ability to regulate both the immune responses and intrinsic brain repair programmes and can alter the function of cells by regulating the activity of scores of genes.

Their results show that a highly specific pathway of gene activation is triggered in NPCs by IFN-g, and that this protein also binds to a receptor on the surface of vesicles. When the vesicles are released by the NPCs, they adhere and are taken up by target cells. Not only does the target cell receive proteins and nucleic acids that can help them self-repair, but it also receives the IFN-g on the surface of the vesicles, which activates genes within the target cells.

The researchers, who were funded by the European Research Council and the Italian MS Society, used electron microscopy and superresolution imaging to visualise the vesicles moving between the NPCs and target cells in vitro.

“Our work highlights a surprising novel role for stem-cell-derived vesicles in propagating responses to the environment,” added Pluchino. “It represents a significant advance in understanding the many levels of interaction between stem cells and the immune system, and a new molecular mechanism to explain how stem-cell therapy works.”

Neural stem cells – master cells that can develop into any type of nerve cell – are able to generate mini “first aid kits” and transfer them to immune cells, according to a study published today.

It represents a significant advance in understanding the many levels of interaction between stem cells and the immune system, and a new molecular mechanism to explain how stem-cell therapy works.

Why live vaccines may be most effective for preventing Salmonella infections

Salmonella bacteria

The BBSRC-funded researchers used a new technique that they have developed where several populations of bacteria, each of which has been individually tagged with a unique DNA sequence, are administered to the same host (in this case, a mouse). This allows the researchers to track how each bacterial population replicates and spreads between organs or is killed by the immune system. Combined with mathematical modelling, this provides a powerful tool to study infections within the host. The findings are published today in the journal PLOS Pathogens.

“We effectively ‘barcode’ the bacteria so that we can see where in the body they go and how they fare against the immune system,” explains Dr Pietro Mastroeni from the Department of Veterinary Medicine at the University of Cambridge, who led the study. “This has provided us with some important insights into why some vaccines are more effective than others.”

The multidisciplinary research team led by Dr Mastroeni used the new technique to look at the effectiveness of vaccines against infection by the bacterium Salmonella enterica, which causes diseases including typhoid fever, non-typhoidal septicaemia and gastroenteritis in humans and animals world-wide. Current measures to control S. enterica infections are limited and the emergence of multi-drug resistant strains has reduced the usefulness of many antibiotics. Vaccination remains the most feasible means to counteract S. enterica infections.

There are two main classes of vaccine: live attenuated vaccines and non-living vaccines. Live attenuated vaccines use a weakened form of the bacteria or virus to stimulate an immune response – however, there are some concerns that the weakened pathogen may become more virulent when used in patients with compromised immune systems, for example people infected with HIV, malaria or TB. Non-living vaccines, on the other hand, are safer as they usually use inactive bacteria or viruses, or their fragments – but these vaccines are often less effective. Both vaccines work by stimulating the immune system to recognise a particular bacterium or virus and initiate the fight back in the event of future infection.

Using their new technique, Dr Mastroeni and colleagues showed that live Salmonella vaccines enhance the ability of the immune system to prevent the bacteria from replicating and spreading to other organs. They can also prevent the spread of the bacteria into the bloodstream, which causes a condition known as bacteraemia, a major killer of children in Africa.

They also found that the antibody response induced by live vaccines enhances the ability of immune cells known as phagocytes to kill bacteria in the very early stages of infection, but that a further type of immune cell known as the T-cell – again stimulated by the live vaccine – is subsequently necessary for control and clearance of the bacteria from the blood and tissues. The killed vaccine, whilst able to boost the phagocyte response via the production of antibodies, did not stimulate a protective form of T-cell immunity and was unable to prevent the subsequent bacterial growth in infected organs or the development of bacteraemia, and was unable to control the spread of the bacteria in the body.

Dr Chris Coward, first author on the study, says: "We have used a collaboration between experimental science and mathematical modelling to examine how vaccines help the immune system control infection. We found that, for Salmonella infections, the immune response induced by a killed vaccine initially kills a proportion of the invading bacteria but the surviving bacteria then replicate resulting in disease. The live vaccine appears superior because it induces a response that both kills the bacteria and restrains their growth, leading to elimination of the infection."

Dr Mastroeni adds: “There is a big push towards the use of non-living vaccines, which are safer, particularly in people with compromised immune systems – and many of the infections such as Salmonella are more prevalent and dangerous in countries blighted by diseases such as HIV, malaria and TB. But our research shows that non-living vaccines against Salmonella may be of limited use only and are not as effective as live vaccines. Therefore more efforts are needed to improve the formulation and delivery of non-living vaccines if these are to be broadly and effectively used to combat systemic bacterial infections. We have used Salmonella infections as a model, but our research approaches can be extended to many pathogens of humans and domestic animals.”

The research was carried out Dr Mastroeni, Dr Coward and colleagues Dr Andrew Grant, Dr Oliver Restif, Dr Richard Dybowski and Professor Duncan Maskell. It was funded by the Biotechnology and Biological Sciences Research Council, which has recently awarded Dr Mastroeni funding  to extend this research to the study of how antibiotics work. The new research aims to optimise treatments and reduce the appearance of antibiotic resistance.

Professor Melanie Welham, BBSRC’s Science Director, said: "To protect our health and the health of animals we rely on, such as livestock, effective vaccines are needed against disease.

Science turns to religion for “mass mobilisation” on environmental change

$

Two eminent scientists have made an impassioned appeal to the world’s religious leaders for help in curbing the potentially catastrophic effects of the ongoing abuse of the planet’s natural resources.

Writing in the journal Science the researchers say that religious leaders can instigate the “massive mobilisation of public opinion” needed to stem the destruction of ecosystems around the world in a way that governments and scientists cannot.

The call is made in an essay, co-written by Partha Dasgupta, an economist at St John’s College, University of Cambridge, and Veerabhadran Ramanathan, a climate and atmospheric scientist at Scripps Institution of Oceanography, University of California, San Diego, who collectively have eight decades of experience researching environmental change and its effects.

Earlier this year, the pair organised a workshop involving more than 50 other academics at the Vatican, during which they also met with the Pope to discuss their concerns.

Their essay appears ahead of the United Nations summit on climate change in New York on September 23, at which Ramanathan will speak about the role that religions can play in mobilising public action on environmental issues. The chief editor of Science, Marcia McNutt, has meanwhile added her voice to the call in a supporting editorial, while Naomi Oreskes, the Harvard-based historian of science and climate change issues, has described the paper as “a watershed moment”.

Professors Dasgupta and Ramanathan describe humanity’s relationship with natural resources as being “at a crossroads”. They argue that this is characterised by a series of feedback loops, in which the planet’s natural capital is exploited to lift people out of poverty, resulting in a demand for food, water and energy that cannot be sustained. The net effect is not only the destruction of vital ecosystems like forests and fisheries, but ongoing poverty for millions of people.

The solution to this, the authors say, is “massive collective action” by people to protect these environmental resources both on an international scale, and within their own communities. Organised religion, they suggest, is uniquely placed to help communities stand in the way of industrial activities and government policies which threaten the planet’s “natural capital”.

“Unsustainable consumption, population pressure, poverty and environmental degradation are intricately linked, but this is appreciated neither by development economists, nor by national governments who permit GDP growth to trump environmental protection in their policies,” they write.

“The transformational step may very well be a massive mobilisation of public opinion by the Vatican and other religions for collective action to safeguard the well-being of both humanity and the environment.”

Professor Dasgupta, whose work focuses on the combined pressures of poverty, population and changes to the natural environment, admitted that it was “very rare” for scientists to appeal to religious leaders in this way.

“Religion has access to networks at every level in a way that scientists do not, and that’s really why we are appealing to them to help address common issues for the sake of a common good,” he said.

“I think that a lot of people see the religious contribution as a cosy topic which we should only discuss on Sunday mornings, but it could prove decisive. An organisation like the Catholic Church is structured in a way that makes it remarkably effective at, for example, leading a famine relief campaign. These are mechanisms that we should be using to tackle other global problems, including stopping governments from riding roughshod over people’s lives with disastrous effects for biodiversity.”

Alongside their potential role in turning public opinion, the paper suggests that religious organisations could provide more practical help, for example by using their charitable arms to provide the world’s poorest people, of whom an estimated 1.5 billion still struggle with pre-industrial technologies, with access to clean energy technologies such as biogas stoves and solar lamps.

Professor Ramanathan, who studies the climate effects of aerosols, has estimated that replacing the solid fuels on which many of the world’s poor rely for cooking, light and heat with more sustainable alternatives could have a significant effect in reducing near-term warming trends. “It is miraculous that eight decades of research by Professor Dasgupta and myself on the natural and social science aspects of environmental changes has led us to the doorstep of moral leaders of religions to rescue humanity from climate change,” he said.

Professor Dasgupta added that religious leaders could realistically collaborate with learned organisations, such as the Royal Society or the US National Academy of Sciences, to structure campaigns aimed at ending the over-exploitation of the planet’s natural resources.

“Not a single person whom we invited to our conference at the Vatican earlier this year turned the opportunity down,” he pointed out. “That suggests to me a cause for optimism; when people are asked to take part in something that involves helping others, there is not much resistance.”

Professor Naomi Oreskes said: “This is a watershed moment. For twenty years, scientists have been reluctant to speak out on the need to change business as usual for fear of being labelled ‘political,’ and reluctant to address the moral dimensions of climate change for fear of being labelled ‘unscientific.’ Now, following in the footsteps of great scientific and moral leaders like Neils Bohr and Albert Einstein, Professors Dasgupta and Ramanathan remind us that we are all responsible for the common good.”

The article, Pursuit of the common good, appears in the 19 September issue of Science.

Ahead of the UN summit on climate change, two leading scholars in the field make a watershed appeal to religious leaders for help in mobilising public opinion on the planet's future.

Quick-change materials break the silicon speed limit for computers

$

The present size and speed limitations of computer processors and memory could be overcome by replacing silicon with ‘phase-change materials’ (PCMs), which are capable of reversibly switching between two structural phases with different electrical states – one crystalline and conducting and the other glassy and insulating – in billionths of a second.

Modelling and tests of PCM-based devices have shown that logic-processing operations can be performed in non-volatile memory cells using particular combinations of ultra-short voltage pulses, which is not possible with silicon-based devices.

In these new devices, logic operations and memory are co-located, rather than separated, as they are in silicon-based computers. These materials could eventually enable processing speeds between 500 and 1,000 times faster than the current average laptop computer, while using less energy. The results are published in the journal Proceedings of the National Academy of Sciences.

The processors, designed by researchers from the University of Cambridge, the Singapore A*STAR Data-Storage Institute and the Singapore University of Technology and Design, use a type of PCM based on a chalcogenide glass, which can be melted and recrystallized in as little as half a nanosecond (billionth of a second) using appropriate voltage pulses.

The calculations performed by most computers, mobile phones and tablets are carried out by silicon-based logic devices. The solid-state memory used to store the results of such calculations is also silicon-based. “However, as demand for faster computers continues to increase, we are rapidly reaching the limits of silicon’s capabilities,” said Professor Stephen Elliott of Cambridge’s Department of Chemistry, who led the research.

The primary method of increasing the power of computers has previously been to increase the number of logic devices which they contain by progressively reducing the size of the devices, but physical limitations for current device architectures mean that this is quickly becoming nearly impossible to continue.

Currently, the smallest logic and memory devices based on silicon are about 20 nanometres in size – approximately 4000 times thinner than a human hair - and are constructed in layers. As the devices are made ever smaller in order to increase their numbers on a chip, eventually the gaps between the layers will get so small that electrons which are stored in certain regions of flash non-volatile memory devices will be able to tunnel out of the device, resulting in data loss. PCM devices can overcome this size-scaling limit since they have been shown to function down to about two nanometres.

An alternative for increasing processing speed without increasing the number of logic devices is to increase the number of calculations which each device can perform, which is not possible using silicon, but the researchers have demonstrated that multiple calculations are possible for PCM logic/memory devices.

First developed in the 1960s, PCMs were originally used in optical-memory devices, such as re-writable DVDs. Now, they are starting to be used for electronic-memory applications and are beginning to replace silicon-based flash memory in some makes of smartphones.

The PCM devices recently demonstrated to perform in-memory logic do have shortcomings: currently, they do not perform calculations at the same speeds as silicon, and they exhibit a lack of stability in the starting amorphous phase.

However, the Cambridge and Singapore researchers found that, by performing the logic-operation process in reverse – starting from the crystalline phase and then melting the PCMs in the cells to perform the logic operations – the materials are both much more stable and capable of performing operations much faster.

The intrinsic switching, or crystallization, speed of existing PCMs is about ten nanoseconds, making them suitable for replacing flash memory. By increasing speeds even further, to less than one nanosecond (as demonstrated by the Cambridge and Singapore researchers in 2012), they could one day replace computer dynamic random-access memory (DRAM), which needs to be continually refreshed, by a non-volatile PCM replacement.

In a silicon-based system, information is shuffled around, costing both time and energy. “Ideally, we’d like information to be both generated and stored in the same place,” said Dr Desmond Loke of the Singapore University of Technology and Design, the paper’s lead author. “Silicon is transient: the information is generated, passes through and has to be stored somewhere else. But using PCM logic devices, the information stays in the place where it is generated.”

“Eventually, what we really want to do is to replace both DRAM and logic processors in computers by new PCM-based non-volatile devices,” said Professor Elliott. “But for that, we need switching speeds approaching one nanosecond. Currently, refreshing of DRAM leaks a huge amount of energy globally, which is costly, both financially and environmentally. Faster PCM switching times would greatly reduce this, resulting in computers which are not just faster, but also much ‘greener’.”

The research was part-funded by the UK Engineering and Physical Sciences Research Council (EPSRC).

Faster, smaller, greener computers, capable of processing information up to 1,000 times faster than currently available models, could be made possible by replacing silicon with materials that can switch back and forth between different electrical states.

As demand for faster computers continues to increase, we are rapidly reaching the limits of silicon’s capabilities

'Besom ling and teasel burrs': John Clare and botanising

$
0
0

In his early years, the poet John Clare worked as a gardener at Burghley House, a Tudor mansion just outside Stamford. Later, he struck up a close friendship with Joseph Henderson, an enthusiastic naturalist and head gardener at Milton Hall, an imposing house set in acres of lush parkland to the north of Peterborough. The letters sent between Clare and Henderson reveal their exchange of expertise, and also their shared interest in expanding their botanical knowledge through the pages of the numerous botanical volumes in the Milton Hall library.

In letters and manuscripts now housed in libraries in Peterborough and Northampton, Clare describes his efforts to grow in his own cottage garden some of the species he has encountered at Burghley and Milton. October 1824 finds him working ‘in the garden at making a shed for my ariculas’. Later, in one of many lists, he records the names of the auriculas he admires but is unable to afford. In November 1824 he notes that he has ‘received a parcel of Ferns & flowers from Henderson the common Polipody…the harts tongue… the Lady fern… tall white Lychnis with seven new sorts of Chrysanthemums…”.

Clare’s deep interest in plants, his love of 'botanising' and the significance of plants in his writing, is the focus of a symposium taking place next week at Cambridge University Botanic Garden. The meeting will bring together botanists, nature writers, artists and literary scholars to look afresh at the poet’s relationship with the environment. It has been the organised by the Centre for John Clare Studies (Faculty of English) set up earlier this year by Dr Paul Chirico, Dr Mina Gorji and Dr Sarah Houghton-Walker to mark the 150th anniversary of Clare’s death.

It was at Northampton General Lunatic Asylum that Clare died, aged 70, on 20 May 1864. His gravestone in Helpston churchyard remembers him as ‘The Northamptonshire Peasant Poet’ and each summer children from the primary school that bears his name lay flowers on his resting place, in the form of Midsummer Cushions - a tradition dating back to Clare’s day of making cushions of turf studded with meadow flowers.

The term ‘Peasant Poet’, with its implications of lack of education, is a label that belies Clare’s intellect as someone hungry for knowledge and quick to learn. As the son of a poor farm labourer, his formal education was at best sporadic and confined to village ‘vestry’ and ‘dame’s schools’; he left school early to take a job to help support his family.

Clare read widely and engaged as much as he was able with contemporary debates on everything from politics to art theory, from religion to natural history.  He tutored himself in mathematics and read a wide range of poetry, prose and drama. Many of his books are now housed in their original wooden bookcase in Northampton Public Library.

Houghton-Walker said: “We hope that next week’s symposium will encourage a conversation about Clare’s intense curiosity regarding the plants he observed in field and garden, and his desire to understand and catalogue them according to the latest scientific methods. He made close observations of plant habitats, recording how different species related to one other, and he collected many botanical specimens. His poems bear witness to his minute observations of flora.”

It is evident, however, that Clare struggled with the Linnaean system and its reliance on hard-to-pronounce Latin nomenclature. In his journal for October 1824, he records a plan to collect a book and ‘call it 'A Garden of Wild Flowers', as it shall contain nothing else with quotations from poets & others an English Botany on this plan woud be very interesting & serve to make Botany popular while the hard nicknaming system of unutterable words now in vogue only overloads it in mystery till it makes it darkness visible’.

Clare enjoyed brief spells of acclaim during his lifetime and gained the support of a number of benefactors. But for many years his poetry lapsed into obscurity. It was only in the early 20th century that writers and editors such as Arthur Symons and Edward Thomas brought his work once again to public attention.  Since then, he has been championed by poets such as Ted Hughes, John Ashbery, Elaine Feinstein, Seamus Heaney and Tom Paulin. Today Clare’s close engagement with the natural world chimes with a resurgence of interest in nature writing.

The poet's celebration of flora and fauna is often discussed in terms of his love of wilderness and his resistance to the enclosure movement and resulting changes in farming practices that were threatening to destroy the countryside he knew ‘with its besom ling and teasel burrs’. Eager to record and preserve, in writing, the environment he felt was under threat, he set himself the task of documenting the natural world around his village in Northamptonshire. In 1824 he began to write down his observations in a group of letters which have come to be known as an unfinished Natural History of Helpston.  Despite the increasing popularity of Clare’s poetry, these were not published until 1983.

The guest speakers invited to address the symposium reflect its aim to mesh together poetry and botany. They include Professor John Parker, former director of the Botanic Garden, as well as its current director, Professor Beverley Glover, who will lead a tour of the Garden’s systematic beds.

Professor Fiona Stafford from Oxford University, an expert on literature and landscape, will talk about ‘Clare and the Splendid Sycamore’. Stafford has delivered two series on 'The Meaning of Trees' for Radio 3. She said: “Clare's wonderful sonnet on 'The Sycamore' is based on first hand observation of a tree that has often been overlooked, and even condemned, for being common and invasive.  Clare's great gift is to see glory in the commonplace - and, in doing so, open the eyes of readers to things so familiar as to be virtually invisible.”

As well as demonstrating his understanding of the interconnectedness of the environment, Clare’s poems reveal that his interest in botanical classification registered and responded to his own feelings about social class. He was born into poverty, one of a pair of twins, the only one to survive, and his tiny frame may have been a result of malnutrition. Like his father, he began work as a farm labourer while still a boy. Beset by terrible depression, he struggled to make ends meet all his life and, as a working class poet, formed relationships with people from different social strata but never felt entirely accepted by them.

Dr Sue Edney from Bath Spa University will look at the ways in which botanical classification is in itself class-based and how plants in their ‘place’ become caught up in this process of identification and division through naming. She said: “Clare’s mingling of Latin names with common English names, of Linnaean systems with ‘natural’ ones, is related to his self-positioning as a natural poet – a poet related to his place – combined with his desire to become an establishment writer.”

The writer Richard Mabey made his name in the early 1970s with his seminal book Food for Free and has since written extensively on people, plants and the things that bind them together. His 2007 book Nature Cure charts his experience of breakdown and recovery – and the role of nature as healer. As a Visiting Fellow at Emmanuel College, where he is working on a book due out next year, he will talk about ‘Clare and the plant’s point of view’, exploring Clare’s distinctive ability to put himself in the position of his poetic subjects – in this case, the plants he loved and wrote about.

Hetty Saunders is just embarking on an MPhil at Wolfson College, Cambridge, where she will be writing a dissertation on Clare and botany. In looking at the complex relationship that Clare created between plants, landscapes and texts, she will discuss the way that Clare often related his writing to plants of the field, and vice versa, as in this quote from his poem ‘Remembrances’: ‘… my poesys all cropt in a sunny hour/As keepsakes and pledges to fade away’.

Among the participants at the symposium will be two artists, Anita Bruce and Kathryn Parsons, members of the five-strong UnEarthed collective who have been resident artists this year at Clare Cottage, Helpston. Kathryn Parson’s  ‘I Found the Poems in the Fields’ renders Clare’s  intimate observations of nature in delicate hand-modelled porcelain. Her creations tell of the layered platelets of lichen colonies from Royce Wood and Lolham Bridges, and the bold architectural plants found at Swaddywell, all sites known and written about by Clare. 

John Clare's Cottage was renovated and established as an educational centre in 2009 by the John Clare Trust, of which Paul Chirico is vice-chair. The cottage has a garden designed by Adam Frost which won a gold medal at the Chelsea Flower Show in 2012. The landscapes around the village, though much affected by agricultural and social changes since Clare’s birth in 1793, still include many of the features that he loved to visit and described so precisely.

The symposium ‘John Clare and Botany’ will take place at the University of Cambridge Botanic Garden on 23 September. The event is fully booked.

Creating a shared resource for the endangered culture of the Kalmyks

$

Early in the 1600s, several groups of Mongols travelled thousands of miles west in search of new pastures for their herds. The migration of the people who became known as the Kalmyks was prompted by tensions between Mongol communities. Their journey lasted several decades and they travelled around 3,000 miles to settle in the wide pastures west of the Caspian Sea. Here they formed the Kalmyk khanate.

In 1771, more than half the Kalmyk population attempted to return to their original homeland of Dzungaria, a region of central Asia then depopulated as a result of the Qing-Dzungar war. Only a third of those who set out on this return migration survived the perilous journey. Those Kalmyks who remained on the southern edge of Europe were incorporated into the expanding Russian Empire.

Today the Kalmyk communities living in the Republic of Kalmykia and the neighbouring region of Astrakhan (part of the Russian Federation) are remarkable in being the only Buddhist nation in Europe. Kalmyk culture, however, has long been considered critically endangered by Western scholars. Existing Western research on their distinctive way of life has been directed chiefly at the relatively small Kalmyk diaspora in the USA.

Now researchers at the Mongolia & Inner Studies Unit of the Department of Social Anthropology, University of Cambridge, have started work on an ambitious project to document the cultural heritage of a people who are estimated to number around 300,000 worldwide. The objective of the project is to provide Kalmyk communities with a resource that can be used to compare, revive and popularise their endangered culture.

Making use of audio and video, the Kalmyk Cultural Heritage Documentation Project will document Kalmyk culture in its broadest sense, including traditional songs and melodies, musical instruments, dances, oral literature, cuisine, crafts, festivals and many other. This unique body of knowledge will be deposited in open-access digital archives so that it can be shared worldwide.

The five-year project is being funded by Arcadia, a charitable fund dedicated to the preservation of at-risk cultural heritage and the environments. The principal investigator is Dr Uradyn Bulag, a social anthropologist known for his research into transnational studies of people, politics and culture – and particularly for his work on Mongolia and Chinese minorities.

“The project will focus on the Republic of Kalmykia and the adjoining Astrakhan region which is home to more than half the worldwide Kalmyk population. It will also look more broadly at Kalmyk communities in China and elsewhere in order to understand the inter-connectedness of Kalmyk culture in the Eurasian context,” said Dr Bulag.

“From the outset the project will involve local Kalmyk scholars and students. We hope that the resource we create will provide a means for long-separated communities to understand, communicate and exchange cultural information with each other.”

Throughout history, the Kalmyk people have been repeatedly displaced and oppressed. Many of the Kalmyks who attempted to return to Dzungaria in the second half of the 18th century perished. Those who survived the trip found themselves divided into various segregated settlements by the powerful Qing Empire.  In the late 19th century they suffered major devastations in the Muslim rebellions in Xinjiang.

The increasingly marginalised Kalmyks who remained in south west Russia were drafted by the Russian government to fight various wars of conquest which exerted a heavy toll on the population. Between 1943 and 1957 the entire community was exiled to Siberia and Central Asia, charged with betraying the Soviet motherland and collaborating with the invading German army.

The fractured nature of the Kalmyk community – and the shifting identity of groups within it - represents a challenge to those seeking to document their culture. “In terms of the project, we are defining as Kalmyk the people who separated from the Oirats of Dzungaria in the 17th century, travelled to Russia where they formed the Kalmyk khanate, and later scattered,” said Dr Bulag.

“We hold that these people have a common culture even though, as a result of historical migration processes, some of them later adopted other identities and are now no longer called Kalmyk. In China and Mongolia, for example, they are known as Torghut.”

Under the Soviet Union, observance of traditional cultural practises was discouraged or banned. With the collapse of Soviet regime, opportunities opened up for minority cultures to rediscover themselves.
“The Kalmyks in Russia lost many of their traditional knowledge bearers in exile and, when were allowed to return in 1957, they found themselves living as a minority in the autonomous republic that bears their name. In these circumstances, post-Soviet Kalmyk cultural revitalisation has been slow and ineffective,” said Dr Bulag.“

"We hope that the Kalmyk Cultural Heritage Documentation Project will help to redress the balance by capturing and archiving an endangered culture and thus breathing new life into its richly distinctive practices.”

The team contributing to the project reflects its ambitious transnational reach. Dr Bulag and Dr Borjigin Burensain (University of Shiga Prefecture, Japan) will be overseeing the gathering of material among Oirat/Kalmyk groups in China. Dr Baasanjav Terbish and Dr Elvira Churuymova (both University of Cambridge) will be working in Kalmykia in collaboration with local Kalmyk scholars.The project benefits from the expertise of Professor Caroline Humphrey (University of Cambridge) who is renowned for her work on Mongolian cultures.

Almost four centuries ago, ancestors of the Kalmyk people trekked across central Asia to form a Buddhist nation on the edge of Europe. Today Kalmyk communities are scattered across Eurasia, with the largest group in the Republic of Kalmykia. A new project will document Kalmyk heritage to produce an online resource to help Kalmyk communities revive their culture. 

From the outset the project will involve local Kalmyk scholars and students. We hope that the resource we create will provide a means for long-separated communities to understand, communicate and exchange cultural information with each other.
