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

Fishmeal alternative aims to protect marine wildlife from overfishing

Technology that transforms organic waste into animal feed could help ease an overreliance on fishmeal in aquaculture. University of Queensland researchers have developed a production process that converts organic waste into biogas to grow a high-protein alternative to fish feed.

Machine learning simulations reveal how plastic transforms into hard carbon

In a new study published in Chemical Science, researchers from the University of Oxford's Department of Chemistry have used machine learning simulations to trace how a common polymer transforms into hard carbon, revealing the atomic-scale processes that give this technologically
