Nevada Gov. Steve Sisolak announced Friday he plans in two weeks to lift the state of emergency he declared during the early days of the coronavirus pandemic
Scientists are tracking a deadly bird flu outbreak that has infected wild birds in more than 30 states. Purging the nation's poultry supply may not be enough to keep the virus from sticking around.
He and his team were stunned by the number of mutations. They felt they'd made a contribution by alerting the world to a dangerous variant. Then came the travel bans for residents of southern Africa.
New research from China suggests people infected with the delta variant have, on average, about 1,000 times more virus in their respiratory tracts than those infected with the original strain.
Data also show more than 230,000 new coronavirus infections on Wednesday and that 113,090 Americans were hospitalized with the virus — a number that's been on the rise.
Here's irony: tobacco plants may be key in preventing COVID-19. Two companies are using the plants to produce proteins for a vaccine. One candidate vaccine is already in a clinical trial.
It's unclear how the Democrat, who says he is asymptomatic, contracted the virus, but earlier this week, he presided over a hearing that included another member who has since tested positive.
Studies show children have lower rates of COVID-19 and have milder symptoms than adults. But there's less information on how much kids spread the coronavirus, which is key to safely reopen schools.
It's just a bit of genetic material wrapped in protein and fat. But the virus behind COVID-19 can wreak havoc deep inside human lungs when it triggers the immune system to go into overdrive.
Christopher Mores is among those trying to unlock secrets of the novel coronavirus. He spends 14-hour days with his team throwing everything they have at this pathogen, looking for ways to defeat it.
What's behind the "14 days of self-quarantine" guidance after exposure to someone with COVID-19 or after travel from a place with a high number of cases? Think of yourself as a potential incubator.
As the virus makes copies of itself, errors may creep in, changing its genetic makeup. Researchers are trying to determine if the changes are significant.
The latest batch of new emojis is coming soon and it contains some wins for science-lovers. But scientists have mixed feelings about some of the new images from nature.
At first, tests were positive for porcine epidemic diarrhea virus. Then something strange happened. The pigs stopped testing positive for that virus — but kept getting sick.
About 30 percent of Americans are predisposed to celiac disease, but only 1 percent get the disease. A new study finds that a common virus may play a role in determining who gets the disease.
