Researchers found that a single dose left persistent changes to the genomes of neurons, a discovery that could have implications for treating addiction.

A star 1,300 light-years away appears to have just consumed one world and is gearing up for seconds.

For more than a decade, the strange light patterns emitted by “Tabby's Star” have sparked speculation about alien megastructures and exotic natural explanations. The discovery of a giant planet is a new twist.

By A star located about 1,300 light-years from Earth shows signs of having devoured one of its planets — and is now gearing up for a second helping, according to a pair of new studies.

For the first time, scientists found that a rocky planet in the habitable zone of its star has an atmosphere. It's the best place to look for alien biosignatures, scientists say.

The mummified remains of 4,000-year-old Egyptian royals suggest that they were buried with weapons because they could use them, not for symbolic reasons.

A team captured first-of-its-kind footage of orcas holding a sunfish carcass still and ramming it so hard that it burst into fragments, which may be a form of social play. “We could hear the sound,” said one researcher.

Scientists have predicted that human linguistic diversity flourished between 3,000 and 1,000 years ago, before declining with the rise of multinational states and colonial expansion.

The nature of dark matter and dark energy are among the biggest mysteries in science. Scientists think an extra “dark dimension” could explain both, and they are putting the idea to the test.

Researchers argue that a lunar biocontainment facility for extraterrestrial samples could prevent “the potential ecological devastation of an invasive extraterrestrial organism.”
