The season in which babies are born can have a dramatic and persistent effect on how their biological clocks function. The imprinting effect, which was found in baby mice, may help explain the fact that people born in winter months have a higher risk of a number of neurological disorders including seasonal affective disorder (winter depression), bipolar depression and schizophrenia.

A widely used arthritis drug reduces the incidence of non-melanoma skin cancers -- the most common cancers in humans -- according to a new study. The COX-2 inhibitor celecoxib (Celebrex), which is approved for the treatment of arthritis and acute pain, led to a 62 percent reduction in non-melanoma skin cancers. In the future, a combination of medications that include sunscreens and COX inhibitors

Mimicking the reflective iridescence of a butterfly's wing, investigators have developed a color-changing patch that could be worn on soldiers' helmets and uniforms to indicate the strength of exposure to blasts from explosives in the field. Future studies aim to calibrate the color change to the intensity of exposure to provide an immediate read on the potential harm to the brain and the subsequ

A new discovery may explain why a tuberculosis vaccine is not as effective for some people as anticipated, and potentially explains why other vaccines do not work as well for some as they do for others.

Researchers have estimated that sea-level rose by an average of about 1 meter per century at the end of the last Ice Age, interrupted by rapid "jumps" during which it rose by up to 2.5 meters per century. The findings will help unravel the responses of ocean circulation and climate to large inputs of ice-sheet meltwater to the world ocean.

Could the bacteria that we carry in our bodies decide who we marry? According to a new study, the answer lies in the gut of a small fruit fly. Scientists recently demonstrated that the symbiotic bacteria inside a fruit fly greatly influence its choice of mates.

Researchers have studied the effects of the presence of dark matter in the Sun. According to their calculations, low mass dark matter particles could be transferring energy from the core to the external parts of the Sun, which would affect the quantity of neutrinos that reach Earth.

Exposure to polluted air early in life led to an accumulation of abdominal fat and insulin resistance in mice even if they ate a normal diet, according to new research. Animals exposed to the fine-particulate air pollution had larger and more fat cells in their abdominal area and higher blood sugar levels than did animals eating the same diet but breathing clean air.
