18 Dec 2012 Their work on a 50 million year old lizard skin identified the presence of teeth (invisible to visible light), demonstrating for the first time that this fossil animal was more than just a skin moult. This was only possible using some of the brightest light in the universe, x-rays generated by a synchrotron.
A bigger melting pot: what the census really tells us
18 Dec 2012 The detailed analysis of the 2011 census data of England and Wales by the University's new research Centre on Dynamics of Ethnicity (CoDE) reveals the term 'ethnic minority' is fast becoming redundant. Previously passionate debates over how segregated we are, they say, should now be a thing of the past.

18 Dec 2012 Whilst conditions such as a severe stroke have been linked to the disease, for many sufferers the tremors and other symptoms of Parkinson's disease can appear to come out of the blue. Researchers at the university's Faculty of Life Sciences have now discovered that a small stroke, also known as a silent stroke, can cause Parkinson's disease.
Our data seems to suggest that both absolute and relative levels of deprivation predict the incidence of schizophrenia." —James Kirkbride Higher rates of schizophrenia in urban areas can be attributed to increased deprivation, increased population density and an increase in inequality within a neighbourhood, new research reveals.
Call to arms issued to scientists over energy policy
In the wake of the publication of the Energy Bill, experts from the Glasgow Media Group at the University of Glasgow and Chatham House are today calling on the scientific community to take a more decisive lead in the debate on energy policy. The recommendations aim to avoid the issue becoming mired in party politics and controversy, as has happened with climate change.

More than two hundred gene locations have now been identified for the chronic bowel condition Crohn's Disease, in a study that analysed the entire human genome. Published today in The American Journal of Human Genetics , scientists at UCL have devised a new method for identifying and mapping gene locations for complex inherited diseases.
Blue cheese gets its distinctive smell
As the nation prepares to tuck into mounds of Stilton this Christmas, researchers have pinpointed for the first time the yeast which helps give blue cheese its distinctive aroma. A study undertaken by academics at the Universities of Nottingham and Northampton has discovered a particular 'secondary microflora' component' is responsible for boosting the smell of blue cheese.

Scientists at the University of Liverpool have found that male mice produce a pheromone that provokes females and competitor males to remember a preference for the place where the pheromone was previously encountered. Some animals, such as moths, use a sensitive tracking system to trace airborne sex pheromones to the source, while others, such as snakes, follow trails of pheromones left on the ground.
The first unequivocal evidence that humans in prehistoric Northern Europe made cheese more than 7,000 years ago is described in research by an international team of scientists, led by the University of Bristol, published today in Nature. By analysing fatty acids extracted from unglazed pottery pierced with small holes excavated from archaeological sites in Poland, the researchers showed that dairy products were processed in these ceramic vessels.
“missing link” of black holes
The discovery of a bingeing black hole that is expelling powerful beams of material has shed new light on some of the brightest X-ray sources seen in other galaxies, according to new research led by Durham University. Using Earth-orbiting X-ray telescopes, including NASA's Swift and the European Space Agency's XMM-Newton satellites, a large international team of astronomers watched as the X-ray emission from the black hole in our nearest neighbouring galaxy, Andromeda - found more than 2 million light years away - brightened and faded over the course of six months.

A study of closely-related bird species has found that they do not coexist in the same region because they remain too ecologically similar and will out-compete each other, not because of geographical barriers or unsuitable habitats. Oxford University scientists examined 'sister' species - species that are each other's closest relatives - of the 'ovenbird' family from South America.
The slower you grow, the longer you live: growth rate influences lifespan
New research from the University of Glasgow suggests that lifespan is affected by the rate at which bodies grow early in life. A paper published today in the journal Proceedings of the Royal Society B outlines how manipulating growth rates in stickleback fish can extend their lifespan by nearly a third or reduce it by 15 percent.

Alternative to fullerenes in organic solar cells - just as exciting
An insight into the properties of fullerene is set to open the door to a new class of electronic acceptors which can be used to build better and cheaper organic solar cells. Organic solar cells have advanced a great deal since they were first invented nearly 20 years ago, but the fullerene component has remained largely the same and this has had a braking effect on the evolution of the technology.

Researchers from the UK and Australia have uncovered a new element of the honeybee's genetic makeup, which may help to explain why bees are so sensitive to environmental changes. Scientists from the University of Sheffield, Queen Mary, University of London and the Australian National University, have found that honeybees have a 'histone code' - a series of marks on the histone proteins around which their DNA is wrapped in order to fit into the nucleus of a cell.
Faulty gene linked to condition in infants
Researchers at King's College London have for the first time identified a defective gene at the root of Vici syndrome, a rare inherited disorder which affects infants from birth, leading to impaired development of the brain, eyes and skin, and progressive failure of the heart, skeletal muscles and the immune system.

Are jurors influenced by special courtroom measures?
Alleged adult rape victims are not disadvantaged in court if they choose to give evidence behind protective screens or via video links, according to new research. The study, jointly led by the University of Leeds and University of Nottingham, is the first of its kind in the UK to examine the impact of the use of technology and special measures in adult rape trials on juror decision-making.

Sleeping pills can increase the risk of pneumonia
PA 361/12 There has been a call for more research into the effects of a class of commonly used sleeping pills after researchers at The University of Nottingham found that patients taking benzodiazepines were at an increased risk of contracting and dying from pneumonia.

Cutting down on fat, without dieting, will result in a slimmer figure - according to new research co-authored by Durham University Findings published today in the British Medical Journal show that exchanging fatty foods for lower fat alternatives will help people shift around three-and-a-half pounds - without dieting.
This research provides critical insight which will hopefully lead to new medical interventions for this disease." —Dr Andrew Grant Findings of Cambridge scientists, published today in the journal PLoS Pathogens , show a new mechanism used by bacteria to spread in the body with the potential to identify targets to prevent the dissemination of the infection process.
Cognitive behavioural therapy can reduce depression and improve quality of life
Cognitive behavioural therapy (CBT) provided alongside drug treatment can help reduce the symptoms of depression and improve patients' quality of life, according to new research. Depression is a very common illness which has a major impact on a patient's life. In the UK between five and ten per cent of the population has the illness at any one time.
