The life-giving sun can be quite rough on genetic material. Most organisms, including plants and many animals, are equipped with a special enzyme in their cells that is quick to repair DNA damage wrought by the sun's ultraviolet (UV) rays . Humans, however, have less effective repair strategies and as a result are prone to painful sunburns and deadly skin cancer . [More]

Researchers have found susceptibility to Behcet's disease, a painful, inflammatory condition, to be associated with genes involved in the body's immune response.

Scientists have discovered a way to predict the organization of nanoparticles in larger forms by treating them much the same as ensembles of molecules formed from standard chemical reactions.

A genetic clue uncovered by scientists enables doctors to predict, for the first time, which children with T-cell acute lymphoblastic leukemia (T-ALL) are unlikely to benefit from standard chemotherapy for the disease and should therefore be among the first to receive new treatments in future clinical trials.

Scientists have found a way to synthesize graphene oxide in bulk in an environmentally friendly way, eliminating toxic and explosive chemicals from the process. They have also found a class of common bacteria breaks down graphene oxide into environmentally benign graphene.

Researchers have found that reducing calorie intake can restrict the growth and spread of brain cancer.

Researchers are have identified a stress hormone in the sea lamprey, using the 500 million-year-old species as a model to understand the evolution of the endocrine system.

As obesity continues to be a worldwide health risk, one of its "side effects" could include less effective birth control for overweight and obese women who use hormonal contraceptives.

The spread of cancer cells in the tongue may be reduced if a gene that regulates cancer cell migration can be controlled, according to new research.
