For an animal with an ivory appendage half the length of its body protruding from the top of its head, a narwhal moves in the water with surprising grace. “It’s almost mesmerizing,” said Greg O’Corry-Crowe, a research professor at Florida Atlantic University who studies marine mammals. “The precision with which they wielded their tusks, it…
Two NASA missions finally launched from the California coast and soared toward the stars late Tuesday night, overcoming a week of delays to get to orbit. Both aim to unravel mysteries about the universe — one by peering far from Earth, the other by looking closer to home. The rocket’s chief passenger is SPHEREx, a…
Astronomers say they have discovered more than 100 new moons around Saturn, possibly the result of cosmic smashups that left debris in the planet’s orbit as recently as 100 million years ago. The gas giant planets of our solar system have many moons, which are defined as objects that orbit around planets or other bodies…

Twelve Americans on the kidney list die every day on average. Scientists first transplanted genetically engineered pig organs into other animals and then to brain-dead human patients. In 2022, researchers received…
Researchers have corrected a disease-causing gene mutation with a single infusion carrying a treatment that precisely targeted the errant gene. This was the first time a mutated gene has been restored to normal. The small study of nine patients announced Monday by the company Beam Therapeutics of Cambridge, Mass., involved fixing a spelling error involving…
In Washington, many protesters declined to share their names publicly, for similar reasons. One woman, who wore a surgical mask and a long, white lab coat with the words “Mad Scientist” on the back in red lettering, described herself only as a federally funded researcher “who’s trying to keep things moving forward in these challenging…
The Trump administration has asked researchers and organizations whose work is conducted overseas to disclose ties to those regarded as hostile, including “entities associated with communist, socialist or totalitarian parties,” according to a questionnaire obtained by The New York Times. The online survey was sent this week to groups working abroad to research diseases like…
Avocados are true superfoods: dense, buttery scoops of vitamins, fat and fiber, all in a hand-size package. We worked for a long time to make them this way. According to a paper published Monday in the Proceedings of the National Academy of Sciences, people in what we today call Honduras made avocados a part of…
