Scientists have identified an entirely new way the brain signals fullness after eating. The findings offer a novel target for therapies that could dramatically curb overeating.

Children diagnosed as being on the autism spectrum by the age of 2.5 were three times more likely to exhibit improvements in core social symptoms than those diagnosed later.

For people with arthritis, exercise reduces pain and lowers levels of inflammatory cytokines. Exercise also increases the production of natural endocannabinoids. Researchers found the way exercise promotes these changes ...

Alternating from spheres to rugby balls is no longer the sole preserve of mercury isotopes, an international team at CERN's ISOLDE facility reports in a paper published in Physical Review Letters.

Exotic laser-produced high-energy-density (HED) plasmas akin to those found in stars and nuclear explosions could provide insight into events throughout the universe. Physicists at the U.S. Department of Energy's (DOE) P...

Scientists studying cosmic rays near the galaxy's center discovered a strange 'barrier' keeping the fast-moving rays from entering the Milky Way's middle.

Cancer cells use tiny tubes to reach out to nearby immune cells and capture their energy-generating mitochondria

Pauli blocking, a quantum phenomenon that makes a dense quantum gas suddenly turn transparent, has now been observed in three independent experiments

An atom's electrons are arranged in energy shells. Like concertgoers in an arena, each electron occupies a single chair and cannot drop to a lower tier if all its chairs are occupied. This fundamental property of atomic ...

A fresh look at what we know about the first covid-19 cases shows that the earliest known case was in a person who worked at the Huanan Market in Wuhan, which was suspected as the source from the start of the pandemic

Here's how to see the partial lunar eclipse early Friday morning (Nov. 19) in person or online.

Here's a look at the cancers with the poorest rate of survival, and why that is.

Instead of using sophisticated sensors to detect their surroundings and navigate safely, drones and robots could listen for reflections of their own mechanical noises

What does it mean when we say that something is extremely cold? A physicist's answer would be: this means that atoms and molecules barely move. For several decades now, physicists have been developing techniques to creat...

Ecosystems such as forests and peatlands are vital stores for carbon, but less than a quarter of these areas worldwide have protected status

Researchers at Institute for Molecular Science in Japan report that novel photon upconversion (UC) system with heterojunctions of organic semiconductors. The solid-state UC system is achieved with an external quantum eff...

The transition away from fossil fuels and towards renewable energy sources is underway, with solar and wind farms popping up everywhere from the UK to China. A new project in the central US will pile on some significant ...

Phonons--the quasiparticle describing lattice vibrations in solids--directly dictates various properties of solid state systems, such as the thermal conductivity, electron mobility, structural stability and conventional ...

Earthquakes, hurricanes and volcanoes have taken countless lives and caused immeasurable damage throughout history.

In the future, smartphones, which almost everyone has, and smart speakers, 3.7 million installed in Japanese households, might save your life. Apart from daily-use features, these devices can read emergency messages alou...

An international research team at the Research Neutron Source Heinz Maier-Leibnitz (FRM II) of the Technical University of Munich (TUM) have developed a new imaging technology. In the future this technology could not onl...

A long-dead tapeworm parasite was causing a Massachusetts man's unexplained symptoms.
