Cancer clinical trials with negative results don't make an immediate splash in the scientific literature, but they do have a long-term impact on cancer research, according to a new study.

Tests with an autonomous golf cart show that the gaming accessory beats other systems at detecting small road obstacles

Some patients with breast cancer, lung cancer and leukemia seem to fare poorly after treatment because of the effects of a particular gene, a new study finds. The gene, called CYP3A7, is normally only active in infancy, ...

Neurons in the brain that have been supplemented with a synthetic gene can be remotely manipulated by a magnetic field, scientists have shown. The finding has implications for possible future treatment of a range of neur...

Researchers have discovered an optimal way to image the bile ducts during gallbladder removal surgeries using a tested and safe dye and a real-time near-infrared florescence laparoscopic camera.

Researchers report that they have found markedly low levels of the protein NLRX1 in multiple laboratory models of colorectal cancer, and in samples of human tissue. Studies have shown that the protein is known to be invo...

Exposure to lead during early development can alter the the gut microbiota, increasing the chances for obesity in adulthood, researcher have found.

An international team of scientists has identified novel gene locations associated with childhood body mass index -- an important measurement related to childhood obesity. This largest-ever genetic study of childhood BMI...

Emerging evidence on the development, 'prodromal' characteristics, and long-term course of schizophrenia provide reasons for optimism for developing new treatments and preventive approaches for this devastating disorder,...

Scientists believe that 'conserved' genes -- those found in life forms that range from bacteria to plants, insects and humans -- perform vital biological functions across species. And limited research on one of those gen...

Researchers have identified a link between the expression of a cancer-related gene and cell-surface molecules that protect tumors from the immune system.

The generally accepted medical maxim that elevated HDL cholesterol is 'good' has been overturned by a multi-center, international study, They show that a certain genetic cause of increased HDL-C may actually be 'bad,' no...

Brain swelling is a strong predictor of death in children with cerebral malaria (a severe form of the disease where parasites have accumulated in brain vessels), and also in mice with experimental cerebral malaria. A hig...
