Scientists at UCL have discovered how immune cells, essential for tackling infections and cancers, are able to 'recycle' material within themselves in order to stay healthy and function, a breakthrough finding which could lead to more effective immunotherapies.
New evidence has confirmed Australia's Yarrabubba crater as the world's oldest preserved impact structure - but did it thaw Earth and end an ice age? The crater is regarded as one of Earth's oldest, but until now has lacked a precise age.
The health of the poorest people in Britain has declined since the mid-20th century, and is worse when compared to those born a century ago, suggests a new UCL-led study. The study, published in the BMJ Journal of Epidemiology and Community Health , compared health and income data from more than 200,000 working-age adults who were born between 1920 and 1970.
Oxytocin, often dubbed the 'love hormone', is known to promote social bonding. Researchers at KU Leuven have now discovered that administering oxytocin to adult men with autism makes them more open to close emotional bonds with others.

The first evidence, reported today, of structural changes in the brains of rodents and humans with diet-induced obesity may help explain one of the most vexing problems of body weight control. Michael W. Schwartz, professor of medicine at the University of Washington, is the senior author of the study.
Researchers from Children of the 90s at the University of Bristol, in collaboration with 22 other studies from across the world, have discovered three new genetic variants associated with the skin condition eczema, a chronic inflammatory disease that afflicts millions of patients around the world. Previous research in Europeans had only identified two major genes, so this is a significant breakthrough that will help diagnose and treat the condition in the long term.
If all the UK's discarded wrapping paper and Christmas cards were collected and fermented, they could make enough biofuel to run a double-decker bus to the moon and back more than 20 times, according to the researchers behind a new scientific study. The study, by scientists at Imperial College London, demonstrates that industrial quantities of waste paper could be turned into high grade biofuel, to power motor vehicles, by fermenting the paper using microorganisms.
A magnetic resonance imaging (MRI) scan for coronary heart disease is better than the most commonly-used alternative, a major UK trial of heart disease patients has shown. The findings by University of Leeds researchers could change the way that people with suspected heart disease are assessed, potentially avoiding the need for tests that are invasive or use ionising radiation.
MINNEAPOLIS / ST. PAUL (12/22/2011) —Researchers from the University of Minnesota's College of Biological Sciences, working with colleagues at the University of California, San Francisco, have discovered a new target for HIV drug therapy that could make it possible for natural human antiviral proteins to destroy HIV.
ANN ARBOR, Mich.-Teens who see movie characters using cigarettes are quicker to try smoking than their peers who did not watch the same scene, a new study finds. However, the exposure to movie images involving cigarettes does not appear to lead teens who have tried smoking to become regular smokers sooner, said Sonya Dal Cin, an assistant professor of communication studies at the University of Michigan and the study's lead author.
Scientific discoveries come through many different means. Breakthroughs can result from purposefully-executed research projects that are perhaps punctuated with unexpected flashes of insight. In rare cases, discoveries occur through a chain of highly improbable, very lucky, occurrences. I strongly prefer my research team to stay on the first path and use their highly developed scientific skills to guide their efforts towards a rational goal.
Yale researchers have uncovered the molecular tricks used by bacteria to fight the effects of fluoride, which is commonly used in toothpaste and mouthwash to combat tooth decay. In the Dec. 22 online issue of the journal Science Express, the researchers report that sections of RNA messages called riboswitches - which control the expression of genes - detect the build-up of fluoride and activate the defenses of bacteria, including those that contribute to tooth decay.
In eukaryotes - the group of organisms that include humans - a key to survival is the ability of certain proteins to quickly and accurately repair genetic errors that occur when DNA is replicated to make new cells. In a paper published in the December 23, 2011 issue of the journal Science, researchers at the Ludwig Institute for Cancer Research and the University of California, San Diego School of Medicine have solved part of the mystery of how these proteins do their job, a process called DNA mismatch repair (MMR).
A collaboration between virologists and neuroscientists at Cambridge University has demonstrated how viruses that cross the blood/brain barrier could be exploited to slow down, or even halt, the progress of Parkinson's and other neurodegenerative diseases.
Researchers from the University of Birmingham and Lancaster University, analysing data taken by the ATLAS experiment, have been at the centre of what is believed to be the first clear observation of a new particle at the Large Hadron Collider. The research is published today (22 December 11) on the online repository arXiv.
A new measurement tool can identify cognitively normal adults who are at high risk for cognitive decline, according to a new study by collaborators at the Perelman School of Medicine at the University of Pennsylvania and Harvard Medical School. The study is published in the December 21, 2011, online issue of Neurology , the medical journal of the American Academy of Neurology.

Scientists at University of Sheffield map out Britain's sun spots Britain is getting brighter according to solar experts at the University of Sheffield who have also revealed the coastal city of Portsmouth was the UK's sunniest place in 2011. At the other end of the sunshine scale, Loch Maree in North West Scotland was found to be the least sunny place in the UK last year.
A protein's function depends on both the chains of molecules it is made of and the way those chains are folded. And while figuring out the former is relatively easy, the latter represents a huge challenge with serious implications because many diseases are the result of misfolded proteins. Now, a team of chemists at the University of Pennsylvania has devised a way to watch proteins fold in "real-time," which could lead to a better understanding of protein folding and misfolding in general.
http://www.berkeley.edu/news2/2011/12/dengue.flv As part of the Howard Hughes Medical Institute's (HHMI) 2010 Holiday Lectures on Science, UC Berkeley's Eva Harris talked about her work with scientists and clinicians in Nicaragua on dengue over the past two decades. Here, several partners in Nicaragua talk about the impact of this collaboration.
ANN ARBOR, Mich.-New research from the University of Michigan suggests obesity can be seen as one of the unintended side effects of free market policies. A study of 26 wealthy nations shows that countries with a higher density of fast food restaurants per capita had much higher obesity rates compared to countries with a lower density of fast food restaurants per capita.
New research from Cambridge University and others shows that, with sensitive ing, young children can be reliable witnesses in cases of abuse.
Are robots welcome in our homes? A qualitative study has revealed some interesting possibilities. Only one out of three households thinks automatic vacuum cleaners are worth the investment. The opinions of the others will be used to develop the appliances of the future. Will there be lots of gadgets under the family Christmas tree this year? By the back door, robotic vacuums are bringing cyberstuff into daily life; they're among the first autonomous devices that can be easily used by ordinary households.
Innovative machine learning method anticipates neurocognitive changes, similar to predictive text-entry for cell phones, Internet search engines At UCLA's Laboratory of Integrative Neuroimaging Technology , researchers use functional MRI brain scans to observe brain signal changes that take place during mental activity.
