The Trump administration is investigating the theory that the virus leaked from a lab. Scientists who work with viruses say that's virtually impossible and point to transmission from an animal.

Scientists dismiss the idea that the coronavirus pandemic was caused by the accident in a lab. They believe the close interactions of people with wildlife worldwide are a far more likely culprit.

President Trump is ready to reopen America — at least the parts where coronavirus is less of a problem. How has his rhetoric throughout the crisis matched with the reality on the ground?

An overblown immune response could be killing a portion of the sick, and some doctors think that new treatments being tested could help at least some of those patients.

Many people can ride the disease out at home, but doctors are getting a better idea of who should seek medical attention and when.

Satellite imagery shared exclusively with NPR suggests that North Korea is moving ahead with plans to expand its capabilities.

As the coronavirus spreads across the United States, researchers say there's only one way out of lockdown: widespread testing for everyone who might be infected with the virus.

The Trump administration says not everyone needs a test, but experts say a strategy of broad testing and isolating the sick is our best way to solve this crisis.

A growing body of evidence shows that people without any major signs of illness can spread the coronavirus.

In Europe, with cases on the rise, researchers are learning more about the spread of the disease. For one, people experiencing mild symptoms appear to be able to spread the virus easily.

The Pentagon is ending a controversial program to fund social science research. It's part of a shift from asking for academic advice toward building new weapons systems.

Dyson's ideas often occupied a space between science fiction and science. He helped design, among other things, a nuclear reactor that could be safely operated "even in the hands of an idiot."

Researchers have conducted a new test on antimatter — matter's weird opposite. The researchers found that anti-hydrogen atoms behave exactly the same as regular hydrogen. But many questions remain.

The arrest of a Harvard researcher late last month has led to questions about a Chinese program to recruit American talent. Prosecutors say it's a form of economic espionage. Scientists disagree.

A NASA investigation of Boeing's newest space capsule has found numerous software bugs that the agency says should have been found in internal testing — and not an unmanned space flight.

The U.S. has reportedly begun patrols with the low-yield weapons, which it says are needed to counter Russia. Critics worry they increase the risk of nuclear war.

As private companies race into orbit, some experts in satellite operations say there isn't enough public infrastructure to keep all the satellites safe.

Activity at the Imam Khomeini Space Center indicates Iran is once again attempting to send a satellite into orbit. Last year, three attempts ended in failure.

SpaceX is launching more of its a mega-constellation of satellites on Friday to provide Internet all over the world, but some are worried the world's space traffic management isn't up to the task.

As investigators learn more about what happened to a Ukrainian International Airlines flight which crashed in Tehran, a growing body of online evidence suggests it was shot out of the sky.
