A coronavirus variant is spreading quickly in India, causing a massive surge in cases. Scientists are rushing to see if vaccines will be effective against this variant. So far, the news is hopeful.

Scientists are trying to determine if the coronavirus variant in India could be the most transmissible variant known.

As India fights a staggering surge of COVID-19, some scientists suspect a reason for the record-breaking outbreak may be a new variant which spreads faster than any other seen so far.

If you imagine viruses as pieces of a jigsaw puzzle, that can help explain what happens when a coronavirus variant comes into contact with human cells.

The term is a reference to two particular mutations in SARS-CoV-2. But the variant in India could carry additional mutations.

For decades, the U.S. has spent many millions hunting down viruses in hope of stopping a pandemic. Yet the efforts failed. A group of researchers thinks there's a better strategy for the future.

There is a lot of information packed into the 300-page report on the origins of the pandemic released this week. Here are three key points that haven't received a great deal of media attention.

In many cultures around the world, parents don't need chore charts or allowances for kids to pitch in around the house. A new study shows how parents in these cultures teach children to be helpful.

The World Health Organization says it will release its report investigating the origins of COVID-19. It concludes that the virus likely came from a bat and a laboratory leak is extremely unlikely.

The report states that the coronavirus most likely did not originate at the wet market in Wuhan and that a lab leak was "an extremely unlikely pathway."

Researchers worry another coronavirus will spill over from a bat or some other creature. They're hunting for sources — and finding evidence that a new pandemic could be around the corner.

All it took was one coronavirus to turn the world upside down. But how many more are out there, lurking in animals? And what's the chance they could jump into people and trigger another outbreak?

Peter Daszak of the investigative team sent to Wuhan says the farms were probably where the coronavirus first jumped from bats to another animal before infecting humans.

In some cultures kids roll their eyes when asked to do chores. In others, they'll pitch in without even being asked. Researchers have identified two key practices to raise helpful children.

At a news conference this week, the World Health Organization made a surprising statement: The coronavirus could possibly transmit on frozen packages of food.

The World Health Organization says scientists need to find out whether the coronavirus can be transmitted through frozen meat shipments — a theory the Chinese government has promoted heavily.

The World Health Organization has wrapped up its investigation in China into the origins of COVID-19. The team said it's highly unlikely the virus leaked from a lab and more research is necessary.

Scientists are looking at a possible link between the mutations in the U.K. and South Africa — and those in a patient in Boston who had living, growing virus in his body for five months.

One day you're worrying about the regular old coronavirus. Then — seemingly out of the blue — there are variants. Worrisome variants! How did they come to be? And why are they likely more contagious?
