A torrent of satellite images and cell phone videos are shaping the public's view of the war in Ukraine. The speed and scale at which the information spreads is powerful, but it can also be deceiving.

Heavy fighting caused a fire to break out near one of the Zaporizhzhia plant's six reactors, but Ukrainian authorities say the fire has been extinguished. Here's what we know.

A fire at Europe's largest nuclear power plant is out — it had been attacked by Russian troops in Ukraine. The U.S. Department of Energy activated its nuclear incident response team as a precaution.

The head of the U.N. atomic watchdog says there was no release of radioactive material after a projectile hit a building at the plant facility.

Russian troops appear to be at the entrance of Ukraine's Zaporizhzhia Nuclear Power Plant and are engaged in active combat. Footage shows what looks like a fire in one of its administrative buildings.

Russian President Vladimir Putin gave orders to his nation's nuclear forces over the weekend, but their exact meaning is unclear. Russia has more nuclear weapons than any other nation.

Scientists are piecing together what led up to a massive eruption in Tonga last month. They found a likely sequence of events.

An anti-vaccine group known for spreading medical disinformation is writing prescriptions for unproven COVID-19 treatments, with the help of a doctor whose medical license was revoked in Alabama.

A station to detect nuclear weapons tests picked up the volcanic eruption in Tonga from Antarctica. Some experts say the blast could be more than 50 megatons, while NASA estimates 6-10 megatons.

Researchers who have been studying the volcano since 2015 say it was likely caused by seawater flowing into a chamber filled with magma.

Researchers who detected environmental DNA, or eDNA, in two zoos say the technique could one day be used to look for endangered species in remote locations in the wild.

The new research affirms what many individuals had reported. But it also shows the changes to the menstrual cycle are mostly minor and brief, more akin to a sore arm than a dangerous reaction.

Researchers sampled air from a zoological park and found DNA from nearby animals. They hope the work can be used to track endangered species in the wild.

Disinformation — about the Jan. 6 attack, COVID-19, vaccines, etc. — shaped the nation's politics in 2021 and likely will continue to do so throughout the coming year.

Biologist and environmental activist E.O. Wilson died on Sunday at the age of 92. Wilson advocated for biodiversity and conservation.

As the U.S. heads into midterm elections next year, the political right and the anti-vaccine movement are drawing ever-closer together — potentially at the cost of thousands of American lives.

An analysis by NPR shows that since the vaccine rollout, counties that voted heavily for Donald Trump have had more than twice the COVID mortality rates of those that voted for Joe Biden.

A few years back, a telescope picked up a radio signal that seemed to be coming from a nearby star. One possibility? Aliens! The story on how this real-life hunt for ET unfolded.

Russia has conducted an antisatellite weapons test. The resulting debris field has forced astronauts on the International Space Station to take shelter while the debris flies by in orbit.

Lee Merritt is a back surgeon with a long history of spreading COVID misinformation. But she renewed her medical license last month.
