Phys.org / Hiroshima blast debris reveals a previously unknown alloy

The Hiroshima blast on Aug. 6, 1945, was one of the most devastating events in human history. Like all nuclear detonations, it created fleeting moments of extreme heat, pressure, mixing and cooling. These conditions can briefly ...

Phys.org / Physicists create Bose–Einstein condensate from ultracold polar molecules

Bose–Einstein condensates are states of matter that form when particles called bosons are cooled to temperatures that are only a fraction of a degree above absolute zero (i.e., 0 Kelvin [-460°F]). In these states, particles ...

Phys.org / Two Arctic charr populations evolved in less than a century, study finds

Evolution, the process through which animals and other living organisms change their inherited traits over time, typically unfolds slowly over thousands or even millions of years. Some species, however, can adapt at a faster ...

Phys.org / Rainfall across the US is increasingly coming from farther away

Before rain falls, the moisture that forms it may have traveled anywhere from just a few kilometers to hundreds or even thousands of kilometers away. It usually begins as water that evaporated from oceans, lakes, forests ...
