Cambridge and Sciences Po to enhance collaboration

Cambridge University NewsFeed - Mon, 11/27/2017 - 12:09

At a ceremony held in Paris on Friday November 24th, representatives from the University of Cambridge and from Sciences Po signed a Memorandum of Agreement to formalise and strengthen the partnership between both institutions.

The stated aim of the document is to develop research links in disciplines including Politics, History and Public Policy, with a strong expectation that the collaboration will develop to encompass other areas of mutual interest.

Covering an initial three-year period, the agreement includes the provision of matched funds by Cambridge and Sciences Po to enable academic workshops and symposia, and to pay for travel grants, short-term research visits, and visiting professorships at both Sciences Po and Cambridge.

Other bilateral activities within its scope include the encouragement of student mobility, and access for Cambridge PhD students to the Sciences Po Teaching Fellowships programme at Sciences Po campuses in Reims, Menton or Le Havre, where lectures are done in English.

One specific outcome of the agreement between Cambridge and Sciences Po will be the organisation of a public conference on “The Future of Europe”, to be held in Paris in 2018, and led by specialists in European studies from both institutions.

Signing on behalf of the University of Cambridge, Professor Eilís Ferran, Pro-Vice-Chancellor for Institutional and International Relations, said: “This Memorandum of Agreement builds on strong existing relationships between our two world-leading universities. It offers us a formal mechanism to strengthen our partnership at a time when collaboration between academic institutions is more crucial than ever before.”

Mr Frédéric Mion, President of Sciences Po, said: “There is a need to maintain and deepen cooperation among excellent academic institutions in Europe. It is the right time to continue strengthening our ties with a world-class University such as Cambridge by developing jointly this innovative and ambitious research partnership in the social sciences. The Memorandum of Agreement is built on that firm conviction. ”

Sciences Po was founded in 1872 as the École Libre des Sciences Politiques to educate the French governing class in the aftermath of the Franco-Prussian War. Today it is one of France’s leading research universities in the social sciences and humanities. It has seven campuses across France, and a record of excellent research in law, economics, history, political science and sociology.


Agreement will enable closer research ties and funding of joint projects

Going underground: Cambridge digs into the history of geology with landmark exhibition

Cambridge University NewsFeed - Fri, 11/24/2017 - 00:01

Uncovering how the ground beneath our feet was mapped for the first time – and revealing some of the controversies and tragedies geology brought to the surface of intellectual debate, Landscapes Below opens to the public on Friday, November 24, at Cambridge University Library.

Featuring the biggest-ever object (1.9mx1.6m) to go on display at the Library: George Bellas Greenough’s 1819 A Geological Map of England and Wales (the first map produced by the Geological Society of London), as well as a visually stunning collection of maps from the earliest days of geology – the exhibition explores how these new subterranean visions of the British landscape influenced our understanding of the Earth. All the maps belonging to the library are going on display for the first time.

“I think the maps are beautiful objects, tell fascinating stories and frame geology in a new light,” said exhibition curator Allison Ksiazkiewicz. “This was a new take on nature and a new way of thinking about the landscape for those interested in nature.

“We show how the early pioneers of this new science wrestled with the ideas of a visual vocabulary – and how for the first time people were encouraged to think about the secretive world beneath their feet.”

As well as maps, Landscapes Below also brings together an extraordinary collection of fossils, artworks and a collection of 154 diamonds, on loan from the Sedgwick Museum of Earth Sciences. Displayed together for the first time, the diamonds were collected, arranged, and produced by Jacques Louis, Comte de Bournon who later became the Keeper of the Royal Mineral Collection for King Louis XVIII.

Another important exhibit on display for the first time is the first edition of George Cuvier and Alexandre Brongniart’s Researches on the Fossil Bones of Quadrupeds (1811), on loan from Trinity College. It examined the geology of the Paris Basin and revolutionised what was considered ‘young’ in geological terms. 

Artists were also keen to accurately depict the geological landscape. After surviving Captain Cook’s ill-fated third voyage of discovery, artist, John Webber returned to England and travelled around the country painting landscapes and geological formations, as seen in Landscape of Rocks in Derbyshire. Christopher Packe’s A New Philosophico-Chorographical Chart of East-Kent (1743), on loan from the Geological Society of London, is a remarkable, engraved map that draws on early modern medicine in the interpretation of the surrounding landscape.

“The objects we’re putting on display show the many different applications of geological knowledge,” added Ksiazkiewicz. “Whether it’s a map showing the coal fields of Lancashire in the 1830s – or revealing how this new science was used for economic and military reasons.”

In many ways, the landscapes the earliest geologists worked among became battlegrounds as a scientific old guard – loyal to the established pursuits of mineralogy and chemistry – opposed a new generation of scientists intent on using the fossil record in the study of the Earth’s age and formation.

Exhibitions Officer Chris Burgess said: “Maps were central to the development of geology but disagreement between its leading figures was common. Maps of the period did not just show new knowledge but represented visible arguments about how that knowledge should be recorded.”

The exhibition also includes objects from those with rather tragic histories, including William Smith – whose famous 1815 Geological Map of England has been described as the ‘Magna Carta of geology’. Despite publishing the world’s first geological map (which is still used as the basis of such maps today), Smith was shunned by the scientific community for many years, became a bankrupt, and ended up in debtors’ prison.

John MacCulloch, who produced the Geological Map of Scotland, did not live to see his work published after his honeymoon carriage overturned and killed him at the age of 61. He spent 15 summers surveying Scotland, after convincing the Board of Ordnance to sponsor the project. There was some dispute about how MacCulloch calculated his mileage and spent the funds, and the Ordnance only paid for six summers’ worth of work. Five summers were paid for by the Treasury and four from his own pocket.

Added Ksiazkiewicz: “Not only do these maps and objects represent years of work by individuals looking to develop a new science of the Earth, they stir the imagination. You can imagine yourself walking across the landscape and absorbing all that comes with it – views, antiquities, fossils, and vegetation. And weather, there’s always weather.”

Landscapes Below runs from November 25, 2017 to March 29, 2018 at Cambridge University Library’s Milstein Exhibition Centre. Admission is free. Opening times are Mon-Fri 9am-6pm and Saturday 9am-16.30pm. Closed Sundays.

A box full of diamonds, volcanic rock from Mount Vesuvius, and the geology guide that Darwin packed for his epic voyage on the Beagle will go on display in Cambridge this week as part of the first major exhibition to celebrate geological map-making.

How to cut your lawn for grasshoppers

Cambridge University NewsFeed - Wed, 11/22/2017 - 00:45

One could be forgiven for wondering what the point of such a question might be. But the solution, proposed by theoretical physicists in the UK and the US, has some intriguing connections to quantum theory, which describes the behaviour of particles at the atomic and sub-atomic scales. Systems based on the principles of quantum theory could lead to a revolution in computing, financial trading, and many other fields.

The researchers, from the University of Cambridge and the University of Massachusetts Amherst, used computational methods inspired by the way metals are strengthened by heating and cooling to solve the problem and find the ‘optimal’ lawn shape for different grasshopper jump distances. Their results are reported in the journal Proceedings of the Royal Society A.

For the mathematically-inclined gardeners out there, the optimal lawn shape changes depending on the distance of the jump. Counter-intuitively, a circular lawn is never optimal, and instead, more complex shapes, from cogwheels to fans to stripes, are best at retaining hypothetical grasshoppers. Interestingly, the shapes bear a resemblance to shapes seen in nature, including the contours of flowers, the patterns in seashells and the stripes on some animals.

“The grasshopper problem is a rather nice one, as it helps us try out techniques for the physics problems we really want to get to,” said paper co-author Professor Adrian Kent, of Cambridge’s Department of Applied Mathematics and Theoretical Physics. Kent’s primary area of research is quantum physics, and his co-author Dr Olga Goulko works in computational physics.

To find the best lawn, Goulko and Kent had to convert the grasshopper problem from a mathematical problem to a physics one, by mapping it to a system of atoms on a grid. They used a technique called simulated annealing, which is inspired by a process of heating and slowly cooling metal to make it less brittle. “The process of annealing essentially forces the metal into a low-energy state, and that’s what makes it less brittle,” said Kent. “The analogue in a theoretical model is you start in a random high-energy state and let the atoms move around until they settle into a low-energy state. We designed a model so that the lower its energy, the greater the chance the grasshopper stays on the lawn. If you get the same answer – in our case, the same shape – consistently, then you’ve probably found the lowest-energy state, which is the optimal lawn shape.”

For different jump distances, the simulated annealing process turned up a variety of shapes, from cogwheels for short jump distances, through to fan shapes for medium jumps, and stripes for longer jumps. “If you asked a pure mathematician, their first guess might be that the optimal shape for a short jump is a disc, but we’ve shown that’s never the case,” said Kent. “Instead we got some weird and wonderful shapes – our simulations gave us a complicated and rich array of structures.”

Goulko and Kent began studying the grasshopper problem to try to better understand the difference between quantum theory and classical physics. When measuring the spin – the intrinsic angular momentum – of two particles on two random axes for particular states, quantum theory predicts you will get opposite answers more often than any classical model allows, but we don’t yet know how big the gap between classical and quantum is in general. “To understand precisely what classical models do allow, and see how much stronger quantum theory is, you need to solve another version of the grasshopper problem, for lawns on a sphere,” said Kent. Having developed and tested their techniques for grasshoppers on a two-dimensional lawn, the authors plan to look at grasshoppers on a sphere in order to better understand the so-called Bell inequalities, which describe the classical-quantum gap.

The lawn shapes which Goulko and Kent found also echo some shapes found in nature. The famous mathematician and code-breaker Alan Turing came up with a theory in 1952 on the origin of patterns in nature, such as spots, stripes and spirals, and the researchers say their work may also help explain the origin of some patterns. “Turing’s theory involves the idea that these patterns arise as solutions to reaction-diffusion equations,” said Kent. “Our results suggest that a rich variety of pattern formation can also arise in systems with essentially fixed-range interactions. It may be worth looking for explanations of this type in contexts where highly regular patterns naturally arise and are not otherwise easily explained.”

UK should invest in global education to improve lives, says report citing Cambridge research

Cambridge University NewsFeed - Tue, 11/21/2017 - 15:40

The House of Commons’ International Development Committee (IDC) has published the results of its inquiry into the Department for International Development (DFID)’s work on global education.

The report, published today, examines DFID’s efforts to ensure the UK is making a significant contribution towards meeting the fourth Sustainable Development Goal agreed by the UN in 2015 –to “ensure inclusive and quality education for all and promote lifelong learning”.

While recognising that DFID is a world leader in promoting education in international development settings, the report calls for increased spending on global education to ensure no child is left behind.

It cites evidence provided by the Faculty of Education’s Research for Equitable Access and Learning (REAL) Centre on the importance of investing in early childhood education and the early years of primary school for benefits in later life.

Drawing on research by the REAL Centre, the IDC’s report states that global spending on pre-primary education is low –DFID’s expenditure on pre-primary education accounts for under 0.6% of its bilateral education budget. Based on the evidence, the report recommends that DFID increases its spending on pre-primary education.

Responding to the evidence, the Minister of State for International Development, the Rt Hon Alistair Burt MP told the inquiry: “It [early childhood education] has not been funded well enough in the past. It has been an area that has been neglected. It does bring the highest returns in the future, and the returns are greatest for the most marginalised children.”

It is widely recognised that getting into school is not enough to ensure children are learning. In many poor countries, children are often spending up to four years in school without being able to read or do basic mathematics.

Drawing further on the REAL Centre’s evidence, the report argues that “it is vital that teachers are equipped with skills to teach in diverse classrooms” to ensure marginalised children –such as children with disabilities—are not excluded from the education process.

The report has tackled the controversial issue of the role of private schooling, a growing phenomenon in low and lower middle income countries. Research by the REAL Centre shows that “low-fee private schools” are not accessible to the poorest families, leading the IDC report to recommend that DFID should continue to prioritise its spending towards government schools.

DFID is currently updating its education priorities through a “policy refresh”. It is hoped that the messages from the IDC report will help to focus resources on the most marginalised –including the poorest girls, and children with disabilities— and on early years of education, which is most likely to benefit children.

Report highlights opportunities and risks associated with synthetic biology and bioengineering

Cambridge University NewsFeed - Tue, 11/21/2017 - 11:50

Rapid developments in the field of synthetic biology and its associated tools and methods, including more widely available gene editing techniques, have substantially increased our capabilities for bioengineering – the application of principles and techniques from engineering to biological systems, often with the goal of addressing 'real-world' problems.

In a feature article published in the open access journal eLife, an international team of experts led by Dr Bonnie Wintle and Dr Christian R. Boehm from the Centre for the Study of Existential Risk at the University of Cambridge, capture perspectives of industry, innovators, scholars, and the security community in the UK and US on what they view as the major emerging issues in the field.

Dr Wintle says: “The growth of the bio-based economy offers the promise of addressing global environmental and societal challenges, but as our paper shows, it can also present new kinds of challenges and risks. The sector needs to proceed with caution to ensure we can reap the benefits safely and securely.”

The report is intended as a summary and launching point for policy makers across a range of sectors to further explore those issues that may be relevant to them.

Among the issues highlighted by the report as being most relevant over the next five years are:

Artificial photosynthesis and carbon capture for producing biofuels

If technical hurdles can be overcome, such developments might contribute to the future adoption of carbon capture systems, and provide sustainable sources of commodity chemicals and fuel.  

Enhanced photosynthesis for agricultural productivity

Synthetic biology may hold the key to increasing yields on currently farmed land – and hence helping address food security – by enhancing photosynthesis and reducing pre-harvest losses, as well as reducing post-harvest and post-consumer waste.

Synthetic gene drives

Gene drives promote the inheritance of preferred genetic traits throughout a species, for example to prevent malaria-transmitting mosquitoes from breeding. However, this technology raises questions about whether it may alter ecosystems, potentially even creating niches where a new disease-carrying species or new disease organism may take hold.

Human genome editing

Genome engineering technologies such as CRISPR/Cas9 offer the possibility to improve human lifespans and health. However, their implementation poses major ethical dilemmas. It is feasible that individuals or states with the financial and technological means may elect to provide strategic advantages to future generations.

Defence agency research in biological engineering

The areas of synthetic biology in which some defence agencies invest raise the risk of ‘dual-use’. For example, one programme intends to use insects to disseminate engineered plant viruses that confer traits to the target plants they feed on, with the aim of protecting crops from potential plant pathogens – but such technologies could plausibly also be used by others to harm targets.

In the next five to ten years, the authors identified areas of interest including:

Regenerative medicine: 3D printing body parts and tissue engineering

While this technology will undoubtedly ease suffering caused by traumatic injuries and a myriad of illnesses, reversing the decay associated with age is still fraught with ethical, social and economic concerns. Healthcare systems would rapidly become overburdened by the cost of replenishing body parts of citizens as they age and could lead new socioeconomic classes, as only those who can pay for such care themselves can extend their healthy years.

Microbiome-based therapies

The human microbiome is implicated in a large number of human disorders, from Parkinson’s to colon cancer, as well as metabolic conditions such as obesity and type 2 diabetes. Synthetic biology approaches could greatly accelerate the development of more effective microbiota-based therapeutics. However, there is a risk that DNA from genetically engineered microbes may spread to other microbiota in the human microbiome or into the wider environment.

Intersection of information security and bio-automation

Advancements in automation technology combined with faster and more reliable engineering techniques have resulted in the emergence of robotic 'cloud labs' where digital information is transformed into DNA then expressed in some target organisms. This opens the possibility of new kinds of information security threats, which could include tampering with digital DNA sequences leading to the production of harmful organisms, and sabotaging vaccine and drug production through attacks on critical DNA sequence databases or equipment.

Over the longer term, issues identified include:

New makers disrupt pharmaceutical markets

Community bio-labs and entrepreneurial startups are customizing and sharing methods and tools for biological experiments and engineering. Combined with open business models and open source technologies, this could herald opportunities for manufacturing therapies tailored to regional diseases that multinational pharmaceutical companies might not find profitable. But this raises concerns around the potential disruption of existing manufacturing markets and raw material supply chains as well as fears about inadequate regulation, less rigorous product quality control and misuse.

Platform technologies to address emerging disease pandemics

Emerging infectious diseases—such as recent Ebola and Zika virus disease outbreaks—and potential biological weapons attacks require scalable, flexible diagnosis and treatment. New technologies could enable the rapid identification and development of vaccine candidates, and plant-based antibody production systems.

Shifting ownership models in biotechnology

The rise of off-patent, generic tools and the lowering of technical barriers for engineering biology has the potential to help those in low-resource settings, benefit from developing a sustainable bioeconomy based on local needs and priorities, particularly where new advances are made open for others to build on.

Dr Jenny Molloy comments: “One theme that emerged repeatedly was that of inequality of access to the technology and its benefits. The rise of open source, off-patent tools could enable widespread sharing of knowledge within the biological engineering field and increase access to benefits for those in developing countries.”

Professor Johnathan Napier from Rothamsted Research adds: “The challenges embodied in the Sustainable Development Goals will require all manner of ideas and innovations to deliver significant outcomes. In agriculture, we are on the cusp of new paradigms for how and what we grow, and where. Demonstrating the fairness and usefulness of such approaches is crucial to ensure public acceptance and also to delivering impact in a meaningful way.”

Dr Christian R. Boehm concludes: “As these technologies emerge and develop, we must ensure public trust and acceptance. People may be willing to accept some of the benefits, such as the shift in ownership away from big business and towards more open science, and the ability to address problems that disproportionately affect the developing world, such as food security and disease. But proceeding without the appropriate safety precautions and societal consensus—whatever the public health benefits—could damage the field for many years to come.”

The research was made possible by the Centre for the Study of Existential Risk, the Synthetic Biology Strategic Research Initiative (both at the University of Cambridge), and the Future of Humanity Institute (University of Oxford). It was based on a workshop co-funded by the Templeton World Charity Foundation and the European Research Council under the European Union’s Horizon 2020 research and innovation programme. 

Wintle, BC, Boehm, CR et al. A transatlantic perspective on 20 emerging issues in biological engineering. eLife; 14 Nov 2017; DOI: 10.7554/eLife.30247

Human genome editing, 3D-printed replacement organs and artificial photosynthesis – the field of bioengineering offers great promise for tackling the major challenges that face our society. But as a new article out today highlights, these developments provide both opportunities and risks in the short and long term.

Opinion: Charles Manson: death of America's 1960s bogeyman

Cambridge University NewsFeed - Tue, 11/21/2017 - 09:58

So, Charles Manson has died, aged 83, of “natural causes”. The con-man, musician and erstwhile cult leader, who came to embody mainstream American fears of the 1960s counterculture “gone wrong”, had an easier death at Kern County hospital in California than any of the seven people whose murders he orchestrated in August 1969.

Manson has been largely out of the public view since his conviction for the Tate-LaBianca killings in January 1971 alongside several members of his “family” – but there has been little diminution of his grisly fame. Earlier this year it was announced that Quentin Tarantino is making a film about the Manson murders. Big names such as Margot Robbie and Brad Pitt are among those said to be lining up for parts.

There remains something strange about the attention that Manson generated in life and now in death. It’s a level of interest which far exceeds matters of public record. As such, it’s difficult to know what to say by way of response to the news of his passing – or even what to say for the purposes of a tentative obituary. Difficult, because it’s hard to know precisely who (or what) the name Charles Manson is being used to describe.

Manson, born Charles Milles Maddox in 1934, spent most of his life behind bars. Before convening the cult-like group “The Family” in 1967, he had convictions for car theft and robbery. But it was towards the end of 1969 that he really came to public attention. He was arrested and put on trial for his role as the mastermind of a total of nine murders, including those of the actress Sharon Tate and four friends, and Leno and Rosemary LaBianca over the course of the weekend of August 8-9 1969. In March 1971 he was given the death penalty which was later commuted to commuted to life imprisonment.

According to testimony at his trial and that of his followers, Manson was not actually directly responsible for wielding a murder weapon at either of the two crime scenes (although there’s plenty to suggest he was involved in other murders at around the same time). But the court found he had masterminded and ordered the Tate-LaBianca killings, made all the more horrific by the fact that actress Tate had been pregnant at the time of her murder.

Different kind of celebrity

Whether you like it or not, from his conviction to his death, Manson was a celebrity. He became a celebrity when he made the cover of Life magazine in December 1969 and Rolling Stone in June 1970 – and subsequent novels, films, recordings, interviews, t-shirts and comic books have sought alternately to shore up this status and to demythologise it.

This Manson culture industry (which shows no signs of slowing down) has kept his name in public circulation for nearly half a century. It’s this material which invariably forms the basis of the analysis whenever Manson’s life and “career” is considered. What becomes visible is something of a schizoid split in which the name Charles Manson gains two points of reference.

There’s “Charles Manson” which effectively describes the life of Charles Milles Maddox, criminal – and then there’s “Charles Manson”, the potent symbol of evil, the name which in the words of one of his recent biographers has become a “metaphor for unspeakable horror”.

An early example of the latter came from the writer Wayne McGuire in 1970. Writing in his column for Fusion magazine, “An Aquarian Journal”, he speculated that at “some point in the future”, Manson would “metamorphose into a major American folk hero”. The comment was later used as the epigraph for The Manson File, a collection of Manson-related writings first published by Amok Press in 1988. The prediction was fully realised in 1997 with the inclusion of Manson in James Parks’ collection, Cultural Icons. Here, nestling between Lata Mangeshkar, Mao Tse Tung and Robert Mapplethorpe, Manson was identified as an “American Murderer” who “channelled his peculiar cocktail of black magic, drugs, sex and rock n roll into homicidal mania”. It is this “peculiar cocktail” that underpins Manson’s symbolic status.

What gives his crimes – and his name – a notoriety in excess of that held by the likes of the Boston Strangler, Albert DeSalvo and the unknown “Zodiac Killer”, who terrorised Northern California in 1968 and 1969, is that they simultaneously interact with a matrix of other powerful symbols that carry a greater cultural resonance than the breaking of a law, however severe.

Hollywood meets the crazies

Tate’s murder brought into collision two heavily mediated zones: Hollywood and the counterculture. Manson’s interest in The Beatles and use of their song title “Helter Skelter” as a blood-drenched slogan further intensified this disturbing elision of murder and popular culture. As with The Rolling Stones’ concert at the Altamont Speedway in December 1969 – at which a member of the audience was murdered by a Hells Angel – the Manson murders, once filtered through media sensitive to their range of connections, become emblems for the “end” or even “death” of the 1960s.

Whether viewed as catalyst or symptom, they are events that stand in for explanations of economic shift, geopolitical crisis and social inequality which describe the decade’s apparent decline into death, violence and what Hunter S. Thompson called “bad craziness”.

If anything it was the Tate-LaBianca murders that carry the metaphorical currency, while the name “Manson” now probably signifies something else. It’s a name to conjure with. “Manson” brings to mind the shadow-side of the 1960s: the incipient violence that lay beneath the counterculture’s day-glo optimism and the lost potential of a decade’s calls for peace and pacifism. When viewed from the vantage point of seeing the long, strange and violent life laid out, it refers also to someone who understood and was able to exploit the potency of the popular culture around him.

There’s very little to celebrate here, but maybe there’s something to learn about what it means to be a celebrity.

Ancient fish scales and vertebrate teeth share an embryonic origin

Cambridge University NewsFeed - Mon, 11/20/2017 - 20:05

In biology, one long-running debate has teeth: whether ancient fish scales moved into the mouth with the origin of jaws, or if the tooth had its own evolutionary inception.

Recent studies on species such as zebrafish showed scales and teeth developing from distinctly different clusters of cells in fish embryos, pouring cold water on ‘teeth from scales’ theories.

However, while most fish in the sea have bones, one ancient lineage – sharks, skates and rays – possess skeletons made entirely of cartilage.

These cartilaginous fish retain some primitive characteristics that have been lost in their bony counterparts, including small spiky scales embedded in their skin called ‘dermal denticles’ that bear a striking resemblance to jagged teeth.  

Now, researchers at the University of Cambridge have used fluorescent markers to track cell development in the embryo of a cartilaginous fish – a little skate in this case – and found that these thorny scales are in fact created from the same type of cells as teeth: neural crest cells.

The findings, published in the journal PNAS, support the theory that, in the depths of early evolution, these ‘denticle’ scales were carried into the emerging mouths of jawed vertebrates to form teeth. Jawed vertebrates now make up 99% of all living vertebrates, from fish to mammals.

“The scales of most fish that live today are very different from the ancient scales of early vertebrates,” says study author Dr Andrew Gillis from Cambridge’s Department of Zoology and the Marine Biological Laboratory in Woods Hole.

“Primitive scales were much more tooth-like in structure, but have been retained in only a few living lineages, including that of cartilaginous fishes such as skates and sharks.

“Stroke a shark and you’ll find it feels rougher than other fish, as shark skin is covered entirely in dermal denticles. There’s evidence that shark skin was actually used as sandpaper as early as the Bronze Age,” says Gillis.

“By labelling the different types of cells in the embryos of skate, we were able to trace their fates. We show that, unlike most fish, the denticle scales of sharks and skate develop from neural crest cells, just like teeth.

“Neural crest cells are central to the process of tooth development in mammals. Our findings suggest a deep evolutionary relationship between these primitive fish scales and the teeth of vertebrates.

“Early jawless vertebrates were filter feeders – sucking in small prey items from the water. It was the advent of both jaws and teeth that allowed vertebrates to begin processing larger and more complex prey.”

The very name of these scales, dermal denticles, alludes to the fact that they are formed of dentine: a hard calcified tissue that makes up the majority of a tooth, sitting underneath the enamel.  

The jagged dermal denticles on sharks and skate – and, quite possibly, vertebrate teeth – are remnants of the earliest mineralised skeleton of vertebrates: superficial armour plating. 

This armour would have perhaps peaked some 400 million years ago in now-extinct jawless vertebrate species, as protection against predation by ferocious sea scorpions, or even their early jawed kin. 

The Cambridge scientists hypothesise that these early armour plates were multi-layered: consisting of a foundation of bone and an outer layer of dentine – with the different layers deriving from different types of cells in unborn embryos.

These layers were then variously retained, reduced or lost in different vertebrate linages over the course of evolution. “This ancient dermal skeleton has undergone considerable reductions and modifications through time,” says Gillis.

“The sharks and skate have lost the bony under-layer, while most fish have lost the tooth-like dentine outer layer. A few species, such as the bichir, a popular fish in home aquariums, have retained aspects of both layers of this ancient external skeleton.”

Latest findings support the theory that teeth in the animal kingdom evolved from the jagged scales of ancient fish, the remnants of which can be seen today embedded in the skin of sharks and skate.

The beauty of engineering

BT and Huawei announce five year collaboration with Cambridge

Cambridge University NewsFeed - Thu, 11/16/2017 - 15:57

This new team, intended to combine the brightest minds from two of the biggest global information, communication and telecommunications (“ICT”) companies with one of the foremost academic institutions in the world, will further strengthen the UK’s status as one of the world’s leading hubs for innovation. Backed by up to £25 million in funding and contributions over the next five years, the research group is expected to focus on projects relating to photonics, digital and access network infrastructure and media technologies, alongside work aimed at enhancing the societal impact of communications technologies.

The research project aims to bring together experts from the BT Labs, the Huawei R&D Team and academics from the University of Cambridge to explore new technologies which have the potential to unlock economic benefits for UK businesses and organisations, such as reducing the cost of network infrastructure and boosting operational performance. The projects are also expected to focus on the critical role that new technologies can play in delivering positive impacts for society, such as those aimed at reducing inequality, particularly for those groups excluded from digital transformation and using ICT technologies to improve resilience of communities to climate change.

Finally, the funding is also intended to be used to support longer-term, ‘blue skies’ research projects being progressed by postgraduate students at the University which are focused on generating benefits for industry and society at large. All these projects will be assessed by an Academic Advisory Board intended to be made up of senior representatives from each of the parties. The University maintains strong links with the hi-tech business cluster of more than 4,700 companies which has sprung up around the Cambridge area. The new research and collaboration team – expected to be based at the University’s Maxwell Centre – will further harness the combined strengths of industry and the very best in academia to strengthen the area’s position as one of the leading technology hubs in Europe.

From left to right: BT CEO, Gavin Patterson, University of Cambridge Vice-Chancellor, Prof Stephen Toope and Huawei CEO, Ken Hu

Following the signing of a Memorandum of Understanding today, the new group is expected to kick off research activity in the first half of 2018 with five to ten researchers from BT and Huawei working alongside their University collaborators.

Prof Stephen Toope, Vice-Chancellor at the University of Cambridge, said:  “The University of Cambridge is delighted to be, once again, demonstrating the importance of its research to business and industry. The world of telecommunications has advanced rapidly over the last two decades. However, there is still work to be done to improve the technologies we use on a daily basis and to ensure that they are long-lived. By working with BT and Huawei we will be able to demonstrate that the insights delivered through our research have a broad impact.”

Gavin Patterson, BT Group Chief Executive said: “BT’s fixed and mobile infrastructure is the engine of the UK economy, so it is essential that we continue to innovate in this space to enhance the UK’s competitiveness on the world stage towards and through Brexit.

“BT currently invests around £500m every year in R&D, and over the last ten years we’ve been the third biggest contributor to the UK’s R&D efforts.

“We believe the best way of ensuring this country remains at the forefront of innovation is by combining the expertise and commercial focus of industry with the fantastic intellectual capital found at our world-leading universities. Working together with Huawei and the University of Cambridge, we will discover the next generation of technologies which promise to deliver huge economic, social and cultural benefits for UK citizens.”

Ken Hu Deputy Chairman and Rotating CEO, Huawei, said: “Technology is changing the world faster than we have ever seen. It will bring many benefits to mankind, and affect nearly every aspect of our lives. Huawei will continue to invest and form partnerships to build out future infrastructure. We have over 80,000 people in research and development globally, working with customers, universities and industry bodies.

“No single organization has all the answers. Partnership is the only way forward in a complex digital age. We look forward to working with BT and the University of Cambridge. Together, we will explore future technologies and help ensure a positive social impact.”

Both BT and Huawei have a long history of working with Cambridge on research projects. Researchers at the BT Labs in Adastral Park recently collaborated with the University’s Cavendish Lab on a project to assess the potential theoretical speeds that can be delivered over the UK’s access network infrastructure. Huawei and the University of Cambridge have been working together for seven years on range of successful research projects including media, communications and other technologies.

BT and Huawei today announced a new five-year initiative which aims to see the two companies establish a joint research and collaboration group at the University of Cambridge.

‘Mini liver tumours’ created in a dish for the first time

Cambridge University NewsFeed - Thu, 11/16/2017 - 08:25

Primary liver cancer is the second most lethal cancer worldwide. To better understand the biology of the disease and develop potential treatments, researchers need models that can grow in the lab and accurately reflect how the tumours behave in patients. Previously, cultures of cells had been used but these are hard to maintain and fail to recreate the 3D structure and tissue architecture of human tumours. 

The researchers created the mini tumours (up to 0.5mm) – termed ‘tumouroids’ – to mimic the three most common forms of primary liver cancer. The tumour cells were surgically removed from eight patients and grown in a solution containing specific nutrients and substances which prevent healthy cells out-competing the tumour cells. 

The team, from the Wellcome/Cancer Research UK Gurdon Institute in Cambridge, used the tumouroids to test the efficacy of 29 different drugs, including those currently used in treatment and drugs in development. One compound, a type of protein inhibitor, was found to inhibit the activation of a protein called ERK in two of the three types of tumouroids, a crucial step in the development of liver cancer.

The researchers then tested this compound in vivo, transplanting two types of tumouroids into mice and treating them with the drug. A marked reduction in tumour growth was seen in mice treated with the drug, identifying a potential novel treatment for some types of primary liver cancer.

The tumouroids were able to preserve tissue structure as well as the gene expression patterns of the original human tumours from which they were derived. The individual subtypes of three different types of liver cancer, as well as the different tumour tissues which they came from, were all still distinguishable even after they had been grown in a dish for a long time. As the tumouroids retain the biological features of their parent tumour, they could play an important role in developing personalised medicine for patients.

The creation of biologically accurate models of tumours will also reduce the number of animals needed in certain experiments. Animal studies will still be required to validate findings, but the tumouroids will allow scientists to explore key questions about the biology of liver cancer in cultures rather than mice. 

Lead researcher Dr Meritxell Huch, a Wellcome Sir Henry Dale Fellow from the Gurdon Institute, said: “We had previously created organoids from healthy liver tissue, but the creation of liver tumouroids is a big step forward for cancer research. They will allow us to understand much more about the biology of liver cancer and, with further work, could be used to test drugs for individual patients to create personalised treatment plans.”

Dr Andrew Chisholm, Head of Cellular and Developmental Sciences at Wellcome said: “This work shows the power of organoid cultures to model human cancers. It is impressive to see just how well the organoids are able to mimic the biology of different liver tumour types, giving researchers a new way of investigating this disease.  These models are vital for the next generation of cancer research, and should allow scientists to minimise the numbers of animals used in research.”

Dr Vicky Robinson, Chief Executive of the NC3Rs which partially funded the work, said: “We are pleased to see that the funds from our annual 3Rs prize, sponsored by GlaxoSmithKline, have furthered Dr Huch's research. Each year the prize recognises exceptional science which furthers the 3Rs, and the work being conducted by Meri and her team is continuing to make progress in this area. This new breakthrough involving liver cancer organoids has the potential to reduce the number of animals required in the early stages of liver cancer research, and provide more biologically accurate models of human tumours.”

This work was funded by a National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs) research prize, Wellcome and Cancer Research UK Cambridge Centre.

New Director of Cancer Research UK Cambridge Institute announced

Cambridge University NewsFeed - Thu, 11/16/2017 - 07:27

The Institute - one of the largest cancer research facilities in Europe - is based in the heart of the Cambridge Biomedical Campus. This close collaboration between scientific research and hospital brings huge benefits for the 6,000 cancer patients that pass through the doors of the hospital every year, as well as patients around the UK and the world.

By focusing on the clinical application of high-quality basic research, the Institute forms a bridge between the laboratory and the clinic, and brings together leading scientists, doctors and nurses. The Institute’s landmark findings include the discovery that breast cancer can be divided up into 10 different diseases, paving way for new treatments, and its pioneering research into blood tests that could one day be used to understand the unique molecular profile of a person’s cancer.

Professor Greg Hannon joined the Cancer Research UK Cambridge Institute in 2014 as a Senior Group Leader. This was after spending more than 20 years at Cold Spring Harbor Laboratory in New York, where he was a Howard Hughes Medical Institute Investigator and chaired the cancer genetics program as part of the Lab’s NCI-designated Cancer Center.

Professor Hannon is internationally recognised for his contributions to small RNA biology, cancer biology, and mammalian genomics. He has a long history in the discovery of cancer genes, and he has developed widely used tools and strategies for manipulation of gene expression in mammalian cells and animals, and exome capture approaches that are now being used to inform personalized medicine in the clinic.

Last year Professor Hannon was announced as one of the first ever winners of Cancer Research UK’s Grand Challenge awards. He and his team will receive up to £20 million for an innovative project to build a 3D tumour that can be studied using virtual reality and which shows every single different type of cell in the tumour. The technology will allow multiple doctors and scientists to look at a tumour at the same time, working together to help diagnose and treat patients better. 

Professor Hannon said: “I’m incredibly honoured to be given this opportunity. I have Simon’s incredible legacy to build upon and the large responsibility to lead what is unquestionably a world-class institute into its next decade.

“I’m eternally grateful to Simon for bringing me to the Cancer Research UK Institute and for providing an atmosphere in which our science can thrive. It will soon be my responsibility to maximize that environment for others by drawing on the wisdom and intellect of my colleagues.”

Professor Hannon will take over from Professor Simon Tavaré on 1 February. Professor Tavaré has led the Institute since 2013 and was a Senior Group Leader since 2006.

Sir Harpal Kumar, Cancer Research UK’s chief executive, said: “I’m delighted that Professor Hannon has been appointed as the next Director of the Cancer Research UK Cambridge Institute. The Institute performs world class research of profound importance across a range of cancer areas. I want to thank Simon for all his hard work over the last few years, taking the institute from strength to strength. I look forward to working with Greg and seeing his enthusiasm helping the Institute achieve even greater levels of success.”

Professor Patrick Maxwell, Regius Professor of Physic at the University of Cambridge, says: “This is excellent news for the cancer community at Cambridge and indeed for the Cambridge Biomedical Campus as a whole. Greg has a strong track record of attracting significant funding and truly pushes the boundaries of cancer research, developing innovative new technologies to explore cancer from all angles – in the case of his new virtual reality work, quite literally.”

Keyhole surgery more effective than open surgery for ruptured aneurysm

Cambridge University NewsFeed - Wed, 11/15/2017 - 09:32

This is the first randomised trial comparing the use of keyhole (endovascular) aneurysm repair versus traditional open surgery to repair ruptured aneurysm, with full midterm follow-up.

Abdominal aortic aneurysm is a swelling of the aorta – the main blood vessel that leads away from the heart, down through the abdomen to the rest of the body. If the artery wall ruptures, the risk of death is high, and emergency surgery is needed.

Three recent European randomised trials showed that keyhole repair does not reduce the high death rate up to three months after surgery compared with open repair. However, mid-term outcomes (three months to three years) of keyhole repair are still uncertain.

An international research team set out to assess three year clinical outcomes and cost effectiveness of a strategy of keyhole repair (whenever the shape of the aorta allows this) versus open repair for patients with suspected ruptured abdominal aortic aneurysm who were part of the IMPROVE trial.

Dr Michael Sweeting from the Department of Public Health and Primary Care at the University of Cambridge, who was involved in the trial, says: “More than 1000 people a year in the UK require emergency surgery to repair a ruptured abdominal aortic aneurysm. Without repair, ruptured aneurysm is nearly always fatal. However, surgery is not without its own significant risks, so we are always looking at ways of reducing the risk to the patient. One option is keyhole surgery, but until now not enough was known about how its outcomes compare to regular, open surgery beyond one year after repair.”

The trial involved 613 patients from 30 vascular centres (29 in the UK – including at Addenbrooke’s Hospital, Cambridge - and one in Canada) with a clinical diagnosis of ruptured aneurysm, of whom 316 were randomised to a strategy of keyhole repair and 297 to open repair.

Deaths were monitored for an average of 4.9 years and were similar in both groups three months after surgery. At three years, there were fewer deaths in the keyhole group than in the open repair group, leading to lower mortality (48% vs 56%). However, after seven years there was no clear difference between the groups.

The need for repeat surgery (‘reinterventions’) related to the aneurysm occurred at a similar rate in both groups, with about 28% of each group needing at least one reintervention after three years.

Average quality of life was higher in the keyhole group in the first year, but by three years was similar across the groups. This early higher average quality of life, coupled with the lower mortality at three years, led to a gain in average quality adjusted life years or QALYs (a measure of healthy years lived) at three years in the keyhole versus the open repair group.

The keyhole group also spent fewer days in hospital (14.4 versus 20.5 in the open repair group) and had lower overall costs (£16,900 versus £19,500 in the open repair group).

The researchers point to some study limitations, such as sample size and midterm data focusing on aneurysm-related events, which may have led to some bias. Nevertheless, they say compared with open repair, there are clear benefits associated with keyhole surgery.

“These findings show that, in the first three years after repair, keyhole surgery can improve outcomes and quality of life for patients compared to open surgery, and is more cost effective and requires less time in hospital – important factors to consider for our stretched health services,” adds Dr Sweeting.

Opinion: What can we learn about you from just one click?

Cambridge University NewsFeed - Tue, 11/14/2017 - 12:03

Whether you like it or not, almost every step you take online is recorded: the websites you visit, the purchases you make, the songs you listen to, the messages you post or read on social sites, and the pages you follow on Facebook. These digital footprints provide a treasure trove of data that can reveal not only what you like and how you see the world, but also who you are as a person.

In our research entitled “Psychological targeting as an effective approach to digital mass persuasion” published in the Proceedings of the National Academy of Science, we show that these digital footprints can be used to influence effectively the behaviour of large groups of people. By targeting consumers with persuasive messages that are tailored to their core psychological profiles (e.g. the degree to which they are extroverted or introverted) it is possible to significantly increase the likelihood that people will take a specific action, such as clicking on an ad or purchasing the promoted product.

The basic principle behind this form of personalised persuasion is not new: marketing practitioners have long used behavioural and demographic data to target consumers with customised messages. What is new, however, is the ability to identify and target audiences based on psychological traits that reflect people’s preferences and needs at a much deeper and instinctual level. Prior targeting might have focused on demographic or behavioural attributes such as ‘women ages 18-45’ who searched for the term ‘Soccer World Cup on Google between 2-4pm’. Psychological targeting, however, can focus on a person’s fundamental character traits and psychological needs, which are known to explain and predict preferences in a broad variety of contexts.

Psychological targeting in action

Across three studies, we targeted more than 3.5 million users on Facebook. As of now, Facebook advertising does not allow marketers to directly target users based on their psychological traits. However, it does so indirectly by offering the possibility to target based on Facebook ‘Likes’. While previous research has shown that one can accurately predict people’s psychological traits after getting their permission to access to their Facebook profiles, we leveraged inherent features of the Facebook advertising platform to target our ads at consumer segments of different psychological profiles. For example, if liking ‘Socialising’ on Facebook correlates with the personality trait of extroversion, and liking ‘Stargate’ goes hand in hand with introversion, then targeting users associated with each of these Likes allows us to separately target extroverted and introverted audiences.

Then, we sent out persuasive appeals in the form of Facebook ads that either aligned with or ran counter to the users’ psychological profiles. Finally, we measured users’ reactions to the ads by counting which ad users clicked on (i.e. clicks) and whether users purchased the product promoted in the ad (i.e. conversions).

In one of the experiments, for instance, we chose an online beauty retailer and created customised ads that could be targeted toward either extroverts or introverts, as identified according to their Facebook Likes. We found that matching the content of persuasive messages to individuals’ psychological characteristics resulted in up to 40% more clicks and up to 50% more purchases than their mismatching or un-personalised messages. Extroverts responded more positively to advertising messages when the beauty retailer’s ad was focused on extroverted preferences and interests (e.g. showing a group of women in a social situation, dancing, and having fun, accompanied by ad copy saying: ‘Dance like no one’s watching (but they totally are)’). Meanwhile, introverts responded more positively to those ads that focused on introverted preferences (e.g. a single woman by herself in a quiet environment, enjoying her ‘me-time,’ accompanied by ad copy saying: ‘Beauty doesn't have to shout’).

Implications: the good and the bad

The ability to influence the behaviour of large groups of people by tailoring persuasive messages to their psychological needs could be used to help people make better decisions, and lead healthier and happier lives. Human nature regularly encourages us to act in ways that focus on short-term benefits and neglect negative long-term consequences: just ask anyone who has ever tried to diet how difficult it is to resist the temptation of a chocolate bar and instead eat an apple. The same can be said about saving money: putting money aside for a rainy day is certainly less enjoyable in the moment than spending it on the new pair of shoes that caught your eye in a store window. So, how can psychological targeting help people overcome their human limitations?

Let’s take the example of saving money. Similar to the way psychological targeting can convince people to buy a product, it can also be used to convince people to save more. When targeting people identified as extroverts, ads could encourage them to imagine spending their savings on an exciting summer holiday with their friends in a vibrant and exhilarating city that allows them to pursue outgoing and social activities. Conversely, when targeting introverts, ads could highlight the ability to invest one’s savings in making their home a more comfortable refuge to escape the hectic outside world. In both cases, psychological targeting could help people to see the benefits of saving, and eventually save more.

On the other hand, psychological targeting could be used to exploit weaknesses in people’s character and persuade them to take action against their best interest. For example, online casinos could target ads at individuals who have psychological traits associated with pathological gambling. In fact, psychological targeting has been covered extensively in the context of its ability to influence the outcome of elections. While the veracity of these claims remains uncertain, our findings illustrate how psychological mass persuasion could be used to manipulate people to behave in ways that are neither in their best interest nor in the best interest of society.

Next steps: fuelling a critical debate

Our findings show that psychological targeting works. The technology is not science fiction; it exists today. To us, the most important discussion we need to have now is not what may or may not have happened in the past, but what we as individuals and as a society can and should do moving forward. Key questions that need to be answered in a critical public discourse are:

How do we as consumers and society-at-large want to use this new technology? In what settings do we want to facilitate its application, and when do we want to restrict it? For which purposes should we use it, for which should we not? Under which agreements should we be allowed to implement it, and with which required a degree of transparency?

The reason we started this research was to provide empirical evidence for the effectiveness of psychological targeting. Our hope is that these findings can support the public debate on this topic by showing both the general public and key decision makers – such as elected officials and business leaders – just how important and timely this topic is. Our belief is that by having an open and transparent discussion, solutions and checks and balances can be developed in the form of policies, regulations and technological counter-measures, which will ensure that psychological targeting serves as a driver for good rather than evil.

Adapted from a story published on Columbia University’s website. 

How effective is psychological targeting in advertising? Dr Sandra Matz, a former PhD student at Cambridge now based at Columbia University, and her co-authors, including Dr David Stillwell from the Cambridge Psychometrics Centre, have published a new study which demonstrates that companies only need one Facebook ‘like’ to effectively target potential customers.
