Evo 2 AI Designs 16 Viable Bacteriophages in Lab Test
Stanford researchers used the large genome model Evo 1 and Evo 2 to design novel bacteriophages based on ΦX174. Of 285 synthesized sequences, 16 inhibited E. coli growth, with some showing over 50 amino acid changes—far more than random mutation would allow. The team suggests such AI could aid phage therapy but warns of potential misuse.

Inouye Solar Telescope Spots Kelvin-Helmholtz Instability
Using the NSF Daniel K. Inouye Solar Telescope, scientists have directly observed Kelvin-Helmholtz instability on the Sun's surface, a phenomenon long theorized but never seen. This discovery could explain how magnetic energy builds up and drives solar flares and coronal mass ejections, and may solve the mystery of why the Sun's corona is millions of degrees hotter than its surface.
