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
