Biophysicists reveal how optogenetic tool works

An international research team has for the first time obtained the structure of the light-sensitive sodium-pumping KR2 protein in its active state. The discovery provides a description of the mechanism behind the light-driven ...

A nice day for a quantum walk

Researchers at the Center for Quantum Information and Quantum Biology at Osaka University used trapped ions to demonstrate the spreading of vibrational quanta as part of a quantum random walk. This work relies on their exquisite ...

Membrane nanopore transport gets picky

Trying to determine how negatively charged ions squeeze through a carbon nanotube 20,000 times smaller than a human hair is no easy feat.
