Ultracold cesium chains give indirect evidence of Bethe strings
Physicists cooled cesium atoms into single-file chains and found indirect evidence of Bethe strings, bound clusters of at least six atoms. Co-author Hanns-Christoph Nägerl says the fit to theory is not proof and does not expect the strings to be long-lived.

Innsbruck physicists prove that some ideal agents gain the most energy by forgetting what they did
Innsbruck physicists prove that, in some environments, an ideal agent extracts the most energy only by forgetting parts of its own action history. Lead author Lukas Fiderer said today's computers are still far from that limit, so for now the result sketches what efficient agents could look like.

Cesium atoms trapped in one-dimensional tubes bind into the Bethe strings predicted in 1931
University of Innsbruck physicists made Bethe strings, predicted by Hans Bethe in 1931, from cesium atoms in thousands of one-dimensional tubes. Because the atoms' attraction is tunable, physicists now have a controllable gas for studying bound states of many particles.

Peter Trebsche and Marion Berranger count 193 complete bars and 307 partial ones from Deinham in Austria, Europe's largest prehistoric iron find, radiocarbon dated to the La Tene period and recovered from gravel heaps that destroyed its context.

Structures of RhoBAST catch one guanosine flipping outward to make room for the dye
Ronald Micura's group in Innsbruck and Aiming Ren's in Zhejiang solved the RNA imaging tag with and without dye bound, and the residue that moves, G38, is what lets the dye leave again fast enough to blink.

Alpine melt outran the stakes measuring it: ETH Zurich's tubes came free of the ice
Andreas Bauder has drilled mass-balance stakes into Swiss glaciers for twenty years. This summer the melt released them, and the monitoring network had to be repaired while it was being read.

Vienna's plan to put a trapped-ion quantum computer inside an electron microscope
The result is mathematical rather than measured: entangle each electron with an ion, combine across electrons, and fewer electrons buy the same signal. No factor is stated anywhere.
