Researchers have made a metal organic framework (MOF) with the highest electron charge mobilities ever observed, along with a technique to improve the conductivity of other MOFs.

Scientists have found evidence that may disrupt conventional understanding about how electrical activity travels in the heart — a discovery that potentially can lead to new insight into medical problems such as heart arrhythmia and sudden cardiac death.

Even before toddlers can form a complete sentence, they are attuned to how others may be judging them, finds a new study.

To better understand how much marijuana or constituent compounds actually get into breast milk and how long it remains, researchers conducted a study.

Researchers have discovered that, over the long-run, the race will indeed go to the slower, steadier animal. An analysis of the reported speeds of animals based on land, air and water shows that some of the world's fastest animals are actually some of the slowest when their movements are averaged throughout their lifetimes, giving credence to Aesop's fable 'The Tortoise and the Hare.'

One third of United States armed forces veterans store at least one firearm loaded with ammunition and unlocked, according to a new study that reports on the first survey of a nationally representative sample of this group regarding storage practices.

About one in five children regularly use prescription medications, and nearly one in 12 of those children are at risk for experiencing a harmful drug-drug interaction. Adolescent girls are at highest risk.

A clock drawing test for detecting cognitive dysfunction should be conducted routinely in patients with high blood pressure, according to new research.
