An effective nasal vaccine could stop the virus that causes COVID-19 right at its point of entry. But devising one that works has been a challenge for researchers.
A vast array of species, including people, use slime for a variety of essential bodily functions. Studying the genetic ancestry of slime surprisingly showcases the role of repetitive DNA in evolution.
Controlled coughing can help people with cystic fibrosis, under supervision and in hospital. But when done at home, it could help spread the coronavirus.
Those little nuggets in your nose are actually a sign your body is working to protect you.
