Dead tree branches are by no means static but move throughout the day. Geoinformatics researchers at Heidelberg University tracked these movements in a study conducted in cooperation with the Finnish Geospatial Research Institute (FGI).

Sound-levitated particles reveal how static charge builds up
When two objects touch and then separate, they can swap tiny amounts of electric charge, even if they are made from exactly the same material. This 'triboelectric effect' is the source of everyday static electricity, but it is still poorly understood in large samples of powder, w

Study finds heat waves speed snowmelt substantially, but rivers respond unevenly
A new study by researchers at Montana State University has found that heat waves substantially accelerate the melting rate of mountain snowpack; however, the resulting water doesn't necessarily produce an immediate increase in streamflow.

Why do people self-harm? The mind-body divide might hold some clues
In Finnish lore, the goddess Kivutar stashes away pain in a mountain for safekeeping. And yet she's also a healer, channeling it into rocks or boiling it down into a less potent form in a huge vat.
