In a study published in Physical Review Letters, physicists have demonstrated that black holes satisfy the third law of thermodynamics, which states that entropy remains positive and vanishes at extremely low temperatures, ...

One of the most elegant theories about the origins of life on our planet is that it was kick-started by a delivery from outer space. This idea suggests that prebiotic molecules—the building blocks of life—were transported ...

Past psychology and behavioral science studies have identified various ways in which people's acquisition of new knowledge can be disrupted. One of these, known as interference, occurs when humans are learning new information ...

For decades, neuroscientists have been trying to pinpoint the neural underpinnings of behavior and decision-making. Past studies suggest that specialized groups of neurons in the mammalian brain, particularly in the cortex, ...

Every second, trillions of tiny parcels travel through your bloodstream—carrying vital information between your body's cells. Now, scientists at the Baker Heart and Diabetes Institute have opened this molecular mail for ...

Speed matters. When an X-ray photon excites an atom or ion, making a core electron jump onto a higher energy level, a short-lived window of opportunity opens. For just a few femtoseconds, before an electron fills the void ...

Researchers from the Center for Food Policy at City St George's, University of London and Scotland's Rural College have set out six key areas for action that could help households cut down on food waste in a new comment article ...

This week, researchers reported that weight and health markers may rebound when patients stop using some of the new hormonal gastric inhibitory polypeptide drugs. A prototype device can restore lost olfactory sense. And a ...

The number of traumatic amputations is rising worldwide—caused by road traffic accidents, accidents at work or during leisure activities, but also as a result of terrorist attacks or war. Only a few specialist clinics are ...

A planet's habitability is determined by a confluence of many factors. So far, our explorations of potentially habitable worlds beyond our solar system have focused exclusively on their position in the "Goldilocks Zone" of ...

A new study has revealed that successful environmental restoration is dependent on bridging the gap between ecological science and understanding the social and economic forces that drive change.

Since the 1950s, humanity has been searching for extraterrestrial life with increasingly sophisticated tools. But after decades of space probes, meteorite analysis, radio telescopes, and UFO investigations, what have we actually ...
