The once-rare 'fabella' bone has made a dramatic resurgence in human knees, but who's likely to have a fabella or two -- and why?

Non-invasive brain stimulation is to be trialled for the first time alongside advanced brain imaging techniques in patients who are minimally conscious or in a vegetative state.

The study, conducted in mice, is the first to show that creatine uptake is critical to the anti-tumor activities of killer T cells, the foot soldiers of the immune system.

Consuming potato puree during prolonged exercise works just as well as a commercial carbohydrate gel in sustaining blood glucose levels and boosting performance in trained athletes, scientists report.

A single dose of a highly diluted VSV-Ebola virus (EBOV) vaccine -- approximately one-millionth of what is in the vaccine being used to help control the ongoing Ebola outbreak in the Democratic Republic of the Congo -- r...

Scientists are developing powerful new devices and technologies to monitor and regulate brain activity. To ensure NIH keeps pace with rapid technological development and help clinicians and researchers ethically fit thes...

Researchers discover a new principle -- how cells protect themselves from mitochondrial defects.

Researchers find genes that help maintain the 50-50 balance between male and female offspring in mice -- and that have major implications for male infertility.

Researchers have discovered an enzyme they believe could be key to preventing Group A Streptococcus infections that cause more than 500,000 deaths worldwide each year. The enzyme works through a novel mechanism of action...

Researchers provide clearer picture of how lungs develop and discover novel markers to differentiate populations of lung cells implicated in lung diseases of premature babies.

A research team paved a way to achieve unexplored III-V semiconductor nanostructures. They grew branched GaAs nanowires with a nontoxic Bi element employing characteristic structural modifications correlated with metalli...

A compound effective in killing chemotherapy-resistant glioblastoma-initiating cells (GICs) has been identified, raising hopes of producing drugs capable of eradicating refractory tumors with low toxicity.

Researchers have developed a new cheap method that can identify highly heterogeneous tumors that tend to be very aggressive, and therefore need to be treated more aggressively.

A molecule that protects plants from overexposure to harmful sunlight thanks to its flamenco-style twist could form the basis for a new longer-lasting sunscreen, chemists have found.

Study identifies rare brain cell types that are unique to male mice, and others that are unique to females. The cells were discovered in the hypothalamus, a region of the brain that governs both aggression and mating beh...
