Physicists show that light can generate electricity even in translucent materials

Some materials are transparent to light of a certain frequency. When such light is shone on them, electrical currents can still be generated, contrary to previous assumptions. Scientists from Leipzig…

Laser excitation of a nucleus

A long-awaited breakthrough opens the door to a new type of atomic clock and the investigation of fundamental questions in physics. After decades of investigation, researchers made an extraordinary quantum…

Probing the effects of interplanetary space on asteroid Ryugu

Samples reveal evidence of changes experienced by the surface of asteroid Ryugu, some probably due to micrometeoroid bombardment. Analyzing samples retrieved from the asteroid Ryugu by the Japanese Space Agency’s…

How the Immune System Learns from Harmless Particles

Our lungs are bombarded by all manner of different particles every single day. Whilst some are perfectly safe for us, others—known as pathogens—have the potential to make us ill. The…

She deciphers how tomato roots communicate

Ora Hazak has always been fascinated by plants and is studying the signals that roots send to the rest of the organism. She aims to understand this communication in order…

Recovering phosphorus from sewage sludge ash

Chemical and heat treatment of sewage sludge can recover phosphorus in a process that could help address the problem of diminishing supplies of phosphorus ores. Valuable supplies of phosphorus could…
