Coal-like material transformed to amorphous graphite and nanotubes in simulations
In a warming world, coal can often seem the "bad guy." But we can do other things with coal besides burn it. A team at Ohio University used the Pittsburgh Supercomputing Center's Bridges-2 system to carry out a series of simulations showing how coal.....»»
As ocean surfaces acidify, a deep-sea acidic zone is expanding, and marine habitats are being squeezed
In the deepest parts of the ocean, below 4,000 meters, the combination of high pressure and low temperature creates conditions that dissolve calcium carbonate, the material marine animals use to make their shells......»»

Researchers pioneer new methods in ultrafast science for sharper molecular movies
Imagine being able to watch the inner workings of a chemical reaction or a material as it changes and reacts to its environment—that's the sort of thing researchers can do with a high-speed "electron camera" called the Megaelectronvolt Ultrafast El.....»»
Controlling magnetism with polarized light: Non-thermal pathway uses inverse Faraday effect
Intense laser pulses can be used to manipulate or even switch the magnetization orientation of a material on extremely short time scales. Typically, such effects are thermally induced, as the absorbed laser energy heats up the material very rapidly,.....»»
Decolonizing a university"s tropical ecology curriculum
A new study of curriculum reading material at the University of Glasgow finds that 94% of recommended tropical ecology authors are white, and that 80% of authors are affiliated with universities outside of the tropics. Dr. Stewart White, Senior Lectu.....»»
