The genomic origins of cyanobacterial morphological diversity

Proceedings of the National Academy of Sciences, Volume 123, Issue 39, September 2026. SignificanceCyanobacteria were Earth’s earliest oxygen-producing organisms, yet the genomic basis of their striking shift between unicellular and multicellular forms has remained unclear. By combining phylogenomics, molecular clocks, and ancestral gene-...

Proton–oxygen collisions put cosmic-ray models to the test

CERN’s ATLAS experiment probes the extreme universe The post Proton–oxygen collisions put cosmic-ray models to the test appeared first on Physics World .

  • Proton–oxygen collisions at LHC tested against cosmic-ray models
  • ATLAS measurements 10x more precise than existing models' differences
  • Results reveal models inaccurately predict particle production in cosmic-ray collisions
