Observing the birth of quasiparticles in real time

The formation of quasiparticles, such as polarons, in a condensed-matter system usually proceeds in an extremely fast way and is very difficult to observe. In Innsbruck, Rudolf Grimm's physics research group, in collaboration ...

Sodium pump could act as molecular light switch

Scientists from Jülich, Grenoble, Frankfurt and Moscow uncovered the atomic structure of KR2, a light-driven transporter for sodium ions which had only recently been discovered. Based on the structural information the team ...

Stiffening the backbone of DNA nanofibers

An international collaboration including researchers from the NIST Center for Nanoscale Science and Technology and the Universidad San Francisco de Quito, Ecuador have fabricated a self-assembled nanofiber from a DNA building ...

Scientists first to mimic nature's vital potassium ion channel

(Phys.org) -- An international team of scientists, including chemist Xiao Cheng Zeng of the University of Nebraska-Lincoln, has created what is in effect a nanoscale sieve that is very selective in what it will allow to pass ...

An icy gaze into the Big Bang

(PhysOrg.com) -- Scientists of the Institute for Quantum Optics and Quantum Information (IQOQI) in Innsbruck, Austria, have reached a milestone in the exploration of quantum gas mixtures. In an international first, the research ...

Pushing the cold frontier in an orderly fashion

Physicists are continually reaching new lows as they reduce the temperatures of samples in their laboratories. But even nano-kelvins are not low enough to overcome the entropy (a measure of the disorder in a system) that ...
