Researchers discovered why bird flu can survive temperatures that stop human flu in its tracks. A key gene, PB1, gives avian viruses the ability to replicate even at fever-level heat. Mice experiments confirmed that fever cripples human-origin flu but not avian strains, especially those with avian-like PB1. These findings highlight how gene swapping could fuel future pandemics.
