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.

New research significantly improves our understanding of how insulin interacts with cells in the human body with implications for the treatments of diabetes.

Allergies and asthma are a continuing health problem in most developed countries, but just how do these ailments develop over the course of a childhood? In a population-based study designed to help answer this question, researchers in Norway found that 40 per cent -- or two of five -- of nearly 5,000 two-year-olds had at least one reported allergy-related disorder.

Researchers have discovered a potential new way to stimulate the immune system to prevent or clear a viral infection. By blocking the action of a key protein in the mouse immune system, they were able to boost immune "memory" in those mice -- work that may one day help doctors increase the effectiveness of human vaccines designed to prevent viral infections.

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.

Five hundred million years ago, spineless chordates slunk through Earth's Cambrian oceans. These unassuming creatures would eventually give rise to more complex vertebrates such as fish, dinosaurs and even us, so they are crucial evidence for scientists trying to trace animal evolution's early steps . But because these organisms lacked bones or shells, the soft-tissue features that managed to survive the fossilization process have made the specimens look very primitive, possibly excessively so.

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.

Researchers have identified a new disease mechanism and therapeutic approach for a type of advanced kidney disease that is a common cause of complications in patients with lupus.
