Electron distributions exhibit velocity-space signatures indicative of the rapid energy released by magnetic reconnection explosions occurring in Earth’s magnetosphere and in plasmas throughout the universe. Here, the authors discover a smile-shaped signature in the electron gradient distribution associated with reconnection occurring at Earth’s dayside magnetopause boundary.

DNA sequencing methods for characterizing microbial communities are well developed for bacteria, archaea and fungi, but less so for eukaryotic parasites and commensals. Here, the authors present an optimized and validated metabarcoding protocol for host-associated eukaryotic communities.

H5N1 avian influenza viruses caused an outbreak in dairy cattle. We show that the potential for avian viruses to replicate in cow cells varies across H5N1 evolution, suggesting that the risk of spillover into mammals differs between variants.
