(Phys.org)—Neurons might not be able to send signals as fast as electrons in wires or photons in fiber, but what if they can communicate using miniature sonic booms? That would be quite a revolutionary discovery. A group ...
Sea level rise puts coastal areas at the forefront of the impacts of climate change, but new research shows they face other climate-related threats as well. In a study published January 14 in Nature Communications, researchers ...

A pair of astrophysicists at Tianjin University, in China, has proposed ways that humans in the distant future might use black holes as an energy source. In their paper published in the journal Physical Review D, Zhan-Feng ...
An extreme heat wave struck the Pacific Northwest in June 2021. Temperatures soared above 40°C (104°F) across Oregon, Washington, and British Columbia, sometimes even approaching 50°C (122°F). Experts estimate that at ...
