Researchers have developed a new method for organizing and prioritizing genetic data. The Combined Annotation-Dependent Depletion method will assist scientists in their search for disease-causing mutation events in human...

Researchers have identified a patient's gender as a clear and simple guidepost to help health-care providers anticipate some of the complex effects of NF1, a genetic disorder.

A phenomenon first seen decades ago and revisited in a new experiment involving quarks could extend one of the most successful theories in physics.

Monarch numbers are rapidly falling, but what can be done to protect them?

According to a statement issued today by the Endocrine Society, the risks and benefits of testosterone therapy for older men with declining levels of the hormone need to be fully evaluated.

In a study, researchers surveyed a random sample of US emergency departments and found substantial variation in the adoption of policies relating to contact precautions.

A scientific team has made a surprising discovery about the brain's hunger-inducing neurons, a finding with important implications for the treatment of obesity.

New genetic evidence strengthens the case that one well-known type of cholesterol is a likely suspect in causing heart disease, but also casts further doubt on the causal role played by another type. The findings may gui...

Researchers have found a "potentially novel therapeutic target" to reduce the rate of deterioration and to promote growth of brain cells damaged by multiple sclerosis. Current therapies can be effective in patients with ...

Moderate aerobic exercise helps to preserve the structure and function of nerve cells in the retina after damage, according to an animal study. The findings suggest exercise may be able to slow the progression of retinal...

Whether beta blockers in perioperative care are protective, safe or harmful continues to be a subject of debate. The new ESC Guidelines will try to clarify some of the controversial issues. In the meantime, the current p...

Despite the fact that heart disease is the leading cause of death for both men and women in the U.S., about three-quarters (74 percent) of Americans do not fear dying from it, according to a recent survey.

A team of researchers has found a clue as to why muscles weaken with age. The team observed a change in homeostatic set points in neuromuscular junction synapses of aged fruit flies.

A new study analyses the risk factors and excess mortality among heroin and cocaine consumers admitted to treatment in Spain. The results reveal that the fatality rate among consumers of both drugs is 14.3 times higher t...

Viruses mutate fast, which means they can quickly become resistant to anti-viral drugs. But viruses also depend on proteins and nutrients provided by their hosts, and therefore one strategy to identify new anti-viral dru...

Through collaboration between the Centers for Disease Control and Prevention (CDC) and members of the clinical-laboratory and non-profit-research communities, 35 DNA samples containing many common RS genetic variants hav...

Given its unique nature, the X chromosome has often been neglected when performing large-scale genetic studies. Because women have two copies of this chromosome and men only one, identifying genetic associations with X c...

Septic shock is caused by excessive and systemic reaction of the entire body against infectious agents, in most cases of bacterial origin. The number of deaths by septic shock in intensive care units is very high and is ...

The lipid-rich membranes of cells are largely impermeable to proteins, but evolution has provided a way through -- in the form of transmembrane tunnels. A new study shows in unmatched detail what happens as proteins pass...

Scientists confirmed a suspect Léger painting is a forgery; they detected faint signatures of Cold War-era nuclear bombs in the canvas that reveal the painting was created after the artist's death.
