Cooperation, despite being now considered the third force of evolution, just behind mutation and natural selection, is difficult to explain in the context of an evolutionary process based on competition between individuals and selfish behaviour. But this puzzle, that has haunted scientists for decades, is now a little closer to be solved by research about to be published on the journal Physical Review Letters.

Scientists can easily explain the structural order that makes steel and aluminium out of molten metal and they have discovered the molecular changes that take place as water turns to ice, but glass blowers have been plying their trade since the first century BC and we have only just begun to understand what makes molten glass solid.

One hundred and fifty years after the construction of Crystal Palace at the Great Exhibition, scientists at The University of Nottingham and the University of California, Berkeley in collaboration with the University of Bath, have presented an explanation of how atoms behave as glass cools and hardens. Their research has just been published online in Science Express, in advance of publication in Science.

Electronic implants that dispense medicines automatically or via a wireless medical network are on the horizon and Australian and US researchers warn of the security risks that will follow.

With the advent of personalized medicine, advances in diagnostics and the miniaturization of sensors and control systems for delivering drugs automatically, the Remote Intelligent Drug Delivery System (RIDDS) may soon be a reality. Such devices, implanted under the skin, would remove the inconvenience of manual drug delivery. By connecting a RIDDS to a wireless medical control center wirelessly patients with physical disabilities, learning difficulties, or who are otherwise unable to give themselves medication could benefit.

According to popular stereotype, young teenagers are shortsighted, leaving them prone to poor judgment and risky decision-making when it comes to issues like taking drugs and having sex and a new study confirms that.    Teens 16 and younger do think about the future less than adults but the reasons may have less to do with impulsivity and more to do with a desire to do something exciting.

The study, by scientists at Temple University, the University of California, Los Angeles, Georgetown University, the University of California, Irvine, and the University of Colorado, is published in the the journal Child Development.

Losing weight is good for all overweight people but for sufferers of obstructive sleep apnea (OSA), a new study shows that losing weight is perhaps the single most effective way to reduce OSA symptoms and associated disorders.  The study is in the American Journal of Respiratory and Critical Care Medicine.

We may be a long way off from using genetics to reliably gauge our risks for specific diseases, say researchers at the University of Pittsburgh Graduate School of Public Health. Yet, many companies currently offer personalized genetic testing for diseases like cancer, heart disease and diabetes, and tout the ability of DNA testing to predict future health risks.

Molecular and cellular biologists have made tremendous scientific advances by dissecting apart the functions of individual genes, proteins, and pathways. Researchers at the University of Wisconsin-Madison College of Engineering are looking to expand that understanding by putting the pieces back together, mathematically.

Scientists have found evidence that a direct interaction between vitamin D and a common genetic variant alters the risk of developing multiple sclerosis (MS).

The research, published on 6 February in the journal PLoS Genetics and funded by the MS Society, suggests that vitamin D deficiency during pregnancy and the early years may increase the risk of the offspring developing MS later in life.

The causes of MS are unclear, but it has become evident that both environmental and genetic factors play a role. Previous studies have shown that populations from Northern Europe have an increased MS risk if they live in areas receiving less sunshine.
