Influenza viruses have a mushroom-shaped protein known as neuraminidase (NA) that is said to have a "dark side" because the structure beneath its mushroom cap has been largely unexplored by science.

Nearly 119,000 birds have been culled at a farm in California after a bird flu called H5N9 was detected among the poultry.
