Seasonal flu causes 290,000–650,000 deaths annually. Vaccines and most antivirals target viral surface proteins, which mutate rapidly each season, so protection wanes and effectiveness drops.

The team, led by Yi-Wei Chang at the University of Pennsylvania, combined two forms of cryo-electron microscopy (cryo-EM), single-particle analysis and cryo-electron tomography, to get atomic ...
