Gallery: Radioactive Reindeer Roam Norway 30 Years After Chernobyl

The death of a lab worker in Russia has authorities looking at whether plague played a role. Even if it did, though, the odds of it spreading are very low.

Seven of 16 planetary vital signs are in their most extreme state ever recorded, and El Niño is here to make matters even worse.

Although the case is considered exceptional, investigators are working to determine how the infection occurred and whether the pathogen played a role in the patient’s death.

While oil is known to float, new research finds that over time it can permeate even extremely deep marine habitats, with animal populations declining by as much as 80 percent.

A global network of detectors are reporting some of the most substantial measurements yet of neutrinos created deep underground by the radioactive elements that power our planet’s tectonic activity.

The new image isn’t just stunning—it may also provide clues about how this star survived its own explosion.

Castelion—a next-generation defense tech company—is building a facility in Rio Rancho Estates that documents show could pose a major fire and chemical hazard to neighboring communities.

Ancient plants reveal that the vestiges of the North American ice sheet started expanding a few thousand years ago, but that climate change caused it to reverse course.

These elusive and reactive particles have been challenging to hold on to and even more challenging to study, but a new method paves the way for tests on the differences between matter and antimatter.

“Detecting a neutrino is like looking for a needle in a haystack,” says Juan Carlos Díaz Vélez, who breaks down why researchers are looking for the cosmic particles under the Antarctic ice.

Here’s what we know about the record-setting El Niño on a record-hot planet, and the most important questions scientists are trying to answer.

Redwoods adapted to a cool, foggy climate. Now a new study shows they slow down photosynthesis when their environment warms.
