Phys.org / Fast-tracking a natural climate solution by compressing millennia of carbon capture into hours

What if it were possible to take a very slow geological process, one that takes thousands of years in nature, and speed it up so that it happens within hours, in order to slow the rate of global warming?

Phys.org / Chemical traces of 2023 Canadian wildfires detected in Maryland months after smoke subsided

In 2023, Canada's worst wildfire season on record produced so much smoke that it spilled across national borders into the United States. At times, a thick haze enveloped much of the U.S. East Coast and triggered "Code Purple" ...

Phys.org / First human DNA-cutting enzyme that senses physical tension discovered

An international research team has identified a human protein, ANKLE1, as the first DNA-cutting enzyme (nuclease) in mammals capable of detecting and responding to physical tension in DNA. This "tension-sensing" mechanism ...
