Research has documented that most men become much more jealous about sexual infidelity than they do about emotional infidelity. Women are the opposite, and this is true all over the world.

A series of experiments studying complex plasmas is taking place on board the international space station ISS. Physicists from Germany will use these experiments to study fundamental structure forming processes to better understand what happens in liquids and solids.

Researchers have developed a microbe that can produce an advanced biofuel fuel directly from biomass. Deploying the tools of synthetic biology, the researchers engineered a strain of E. coli bacteria to produce biodiesel and other important chemicals derived from fatty acids.

In the new Swedish-Finnish study, published in Nature Genetics, the researchers identified five loci that predispose to an SLE-related disease in Nova Scotia duck tolling retrievers. The study indicates that the homogeneity of strong genetic risk factors within dog breeds make dogs an excellent model in which to identify pathways involved in human complex diseases. The results of the study also open the door for further studies of specific T-cell activation pathways in human populations.

Boys face high rates of a variety of mental health issues, in addition to lagging behind girls in academic performance and college attendance, according to two new studies. The studies note that boys have higher rates of suicide, conduct disorders, emotional disturbance, premature death and juvenile delinquency than their female peers, as well as lower grades, test scores and college attendance rates.

Global warming may impair the ability of ecosystems to perform vital services -- such as providing food, clean water and carbon sequestration -- says the nation's largest organization of ecological scientists. In a statement released Jan. 26, the Ecological Society of America outlines strategies that focus on restoring and maintaining natural ecosystem functions to mitigate and adapt to climate change.

Scientists are helping to find answers to one of the most difficult problems facing the world today: generating energy without accelerating climate change or harming food production. Researchers are investigating biofuels generated from wastes. These are seen by many as the 'green alternative' to using fossil fuels.

Scientists have discovered a novel survival factor whose rapid transport along nerve cells is crucial for keeping them alive. The same factor seems likely to be needed to keep our nerves healthy as we age.

Expert consumers like to be surprised by unusual product presentation, while novices crave familiarity, so claims a new study.

Using combined and intensive treatments and restructuring care to treat obesity like other chronic diseases may help primary care clinicians and patients better address the condition, according to several new studies.
