adenovirus produced IL-6 within hours. "They were cranking out this protein even without us tickling them to do that," says Wilson. "Unfortunately, until we saw this reaction in the human, we didn't know what to focus on in the mouse or monkey." Wi...
Atmospheric aerosols impact on smog formation being reassessed
