Phys.org / Probing the quantum nature of black holes through entropy
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, ...
Phys.org / Asteroid loaded with amino acids offers new clues about the origin of life on Earth
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 ...
Phys.org / Humans and artificial neural networks exhibit some similar patterns during learning
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 ...
Medical Xpress / Specialized neuron populations in the mouse cortex coordinate to guide correct decisions, study suggests
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, ...
Phys.org / The body's molecular mail revealed: Scientists decode blood's hidden messengers
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 ...
Phys.org / Rapid X-ray pulses enable 100-fold efficiency boost for photoionization
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 ...
Phys.org / Six strategies identified to help households cut down on food waste
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 ...
Phys.org / Saturday Citations: Cute squid with scary name; potential detection of dark matter; fate of the AMOC
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 ...
Medical Xpress / Innovative care system aims to save severed limbs
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 ...
Phys.org / Why being in the 'right place' isn't enough for life
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 ...
Phys.org / New review highlights the pathway to ecological success
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.
Phys.org / What seven decades of hunting for aliens tells us
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 ...
