Unless you're a nut, cute little squirrels pose little threat – but they could have a surprising murderous streak. After watching squirrels in California for 12 years, scientists have seen them actively hunt and kill small rodents this past summer.

Astronomers have discovered an exoplanet with a tail, like a gigantic comet. The planet, known as WASP-69b, is slowly evaporating in the radiation of its host star.

In what seems like a remarkably obvious move, ESA is working with the Portuguese Space Agency and the Portuguese Navy to use life aboard a naval submarine to learn more about the effects of isolation during long-term space missions.

Using principles from rocket science, researchers have created carbon with a record-breaking surface area. The material can soak up about twice the amount of CO2 as current activated carbon materials and has impressive energy-storage capabilities.

The two NASA astronauts "not stranded" on the International Space Station (ISS) are "not stranded" for another month. Due to a delay in the next crew rotation mission, Butch Wilmore and Suni Williams will remain on the station until late March.

A new study from Caltech calculates that our brains process information at the extremely slow speed of just 10 bits per second. This leisurely pace may have long evolutionary roots, despite our sensory systems gathering data 100 million times faster.

Traffic in the vicinity of Antarctica has become a bit trickier now that A23a, the world's oldest and largest iceberg, has broken free of its watery trap north of the South Orkney Islands and is floating northward on the Antarctic Circumpolar Current.

Future space helicopters may benefit as NASA completes history's first interplanetary aircraft crash inquiry. The yet-to-be-released technical report explains why the space agency's Ingenuity Mars helicopter crashed on January 18, 2024.

Scientists at North Carolina State University have created a magnetic “metasheet” that can move objects and liquids around without needing robot arms or grippers.

Scientists have accidentally discovered a particle that has mass when traveling in one direction, but no mass while moving in a different direction. Known as semi-Dirac fermions, particles with this bizarre behavior were first predicted 16 years ago.
