Invisible Labor and the “Ghost Particle”: Underground Physics at the Kolar Gold Fields**

Berichte zur Wissenschaftsgeschichte, EarlyView.
Abstract When cosmic rays—high‐energy particles from outer space—encounter the Earth's atmosphere, they produce particles called neutrinos. To detect them, physicists go underground inside deep mines where the overlying rock can filter out the cosmic‐ray background radiation.

A Biocatalytic Cascade for the Valorization of Sugars

ChemCatChem, EarlyView.
We report a one‐pot, three‐step biocatalytic cascade to synthesize trihydroxy‐piperidine and ‐azepane iminosugars directly from monosaccharides, employing transaminase (ATA) and galactose oxidase (GOase) enzymes. Abstract Biocatalytic cascades offer products of multistep synthesis without the use of protecting groups or isolation of intermediates. This
