A daily low dose of aspirin may help a subgroup of women, those who have previously lost a pregnancy, to successfully conceive and carry a pregnancy to term, according to an analysis by NIH researchers.

In a study of mice and monkeys, NIH-funded researchers showed that they could prevent and reverse some of the brain injury caused by the toxic form of a protein called tau.

A study in the journal "Brain" describes what could be considered a direct “aquarium-to-bedside” approach, taking a drug discovered in a genetic zebrafish model of epilepsy and testing it, with promising results, in a small number of children with the disease.

Research teams from NIH and abroad have identified the first inhibitor of an enzyme long thought to be a potential drug target for fighting disease-causing parasites and bacteria.

Scientists funded by NIH have found that an experimental treatment cured 100 percent of guinea pigs and rhesus monkeys in late stages of infection with lethal levels of Marburg and Ravn viruses, relatives of the Ebola virus.

A new study shows that young people experiencing first episode psychosis have a much higher death rate than previously thought.

NIH-funded scientists have developed a 3-D micro-scaffold technology that promotes reprogramming of stem cells into neurons and supports growth of neuronal connections capable of transmitting electrical signals.

Researchers funded by NIH have discovered the cellular switch that boosts the activity of sperm cells so that they can travel to the egg.

Researchers have confirmed that certain heart rhythm medications, when given by paramedics to patients with out-of-hospital cardiac arrest who had failed electric shock treatment, improved likelihood of patients surviving transport to the hospital.
