Phys.org / Astronomers map a magnetic 'skeleton' funneling gas into a stellar nursery

Stars form when vast clouds of cold gas in space collapse under their own gravity. But not all gas collapses, and not all clouds form stars equally efficiently. A longstanding puzzle in astrophysics is what controls this ...

Phys.org / Using less, living better: Demand-side climate action wins public support

Climate strategies are still judged largely across two dimensions: how much they cost and how many tons of CO2 they save. A new study published in Communications Sustainability argues that this narrow lens overlooks much ...
