Phys.org / Neutron star P13 shows dramatic X-ray variability linked to rotation velocity

A research team has investigated long-term X-ray variability in the neutron star NGC 7793 P13, an object thought to be driven by supercritical accretion, where an extraordinary amount of gas falls onto the object and emits ...

Phys.org / Hundreds of iceberg earthquakes detected at the crumbling end of Antarctica's 'doomsday glacier'

Glacial earthquakes are a special type of earthquake generated in cold, icy regions. First discovered in the Northern Hemisphere more than 20 years ago, these quakes occur when huge chunks of ice fall from glaciers into the ...

Dialog / Typhoons vacuum microplastics from ocean and deposit them on land, study finds

Tropical storms such as typhoons, hurricanes, and cyclones are Earth's most powerful weather systems. Born over warm oceans, they travel thousands of kilometers to land, traversing waters now polluted with plastics, from ...

Phys.org / Ultrashort laser pulses catch a snapshot of a 'molecular handshake'

Liquids and solutions are complex environments—think, for example, of sugar dissolving in water, where each sugar molecule becomes surrounded by a restless crowd of water molecules. Inside living cells, the picture is even ...

Dialog / Cracking the mystery of heat flow in few-atoms thin materials

For much of my career, I have been fascinated by the ways in which materials behave when we reduce their dimensions to the nanoscale. Over and over, I've learned that when we shrink a material down to just a few nanometers ...
