A new study reveals the key lies not in the production of a regrowth molecule, but in that molecule's controlled destruction. The discovery could inspire future regenerative medicine.
Jules Gill-Peterson doesn’t want to fight for trans joy. She wants to fight for what trans people really need: resources, hormones, and surgery. Her latest arena? The US Supreme Court.
An investigational drug developed by Eolo Pharma is showing promise in animal experiments and an early human trial. It could eventually be an alternative or add-on to popular GLP-1 medications.
The Tianwen-2 probe has sent a self-portrait as it heads toward one of the most enigmatic objects in our space neighborhood: the quasi-moon Kamo‘oalewa.
House Democrats sent letters to the potential buyers of the genetic testing company, asking how they plan to protect customer genetic data under a change of ownership.
Using a neural network trained with simulations of supermassive black holes, astronomers have found that the one at the center of the Milky Way, Sagittarius A*, likely rotates at maximum speed.
An AI-related provision in the “Big Beautiful Bill” could restrict state-level legislation of energy-hungry data centers—and is raising bipartisan objections across the US.
So-called “less-lethal” weapons like those that have been used against demonstrators in Los Angeles can cause severe, lasting harm like nerve or brain damage or blindness. They can also kill.
A novel suggestion that complexity increases over time, not just in living organisms but in the nonliving world, promises to rewrite notions of time and evolution.
Beyond the jokes about its new shuttle service are serious questions about what it will mean for struggling transit systems, air quality, and congestion.
Here’s how to find reliable information and keep safe during the summer heat and hurricane season following the unprecedented cuts at federal agencies.
A study claimed that people who eat high-fat, low-carb diets weren’t seeing their arteries fill up with plaque, despite having high levels of blood cholesterol. Critics disagreed—and all hell broke loose.
Researchers estimate that MoM z14 was created 280 million years after the Big Bang, 10 million years earlier than the previous most primitive galaxy recorded.
Rose Yu has drawn on the principles of fluid dynamics to improve deep learning systems that predict traffic, model the climate, and stabilize drones during flight.
Off-world agriculture has long seemed experimental, but that could soon change thanks to a collaboration between design firm Heatherwick Studio and the space architecture nonprofit Aurelia Institute.
Anna’s hummingbirds have evolved to have longer, larger beaks to access backyard feeders in urban areas. It could be a step toward becoming a “commensal” species that lives alongside humans, like pigeons.
Researchers are trying to understand more about the biological and social differences that contribute to later diabetes diagnoses and worse outcomes in women.
Galactic bones, filaments of radio-wave-emitting particles, run through our galaxy, and one of them has a fracture. New analysis suggests collision with a neutron star may have caused it.
For anyone in the US who can afford to go solar, “now would be the time,” because House Republicans want to end federal tax credits that make it affordable.
The Enhanced Games, where athletes are allowed to take performance-enhancing drugs, will host its first event in May. One “enhanced” former Olympic swimmer has already broken the 50-meter freestyle record.
A tiny but crucial agency that maintains physical coordinates like latitude and longitude in the US is struggling as the Trump administration forces out federal employees.
On Earth there is no record of Niallia tiangongensis, a bacterium found aboard the Tiangong station that appears to be well adapted to conditions there.
Scientists were able to create a bespoke treatment for KJ Muldoon’s rare genetic disorder within six months. It could be a blueprint for potentially life-saving, gene-editing Crispr therapies.
As the FDA halts the sale of Ozempic and Zepbound copycats, online clinics have begun offering liraglutide, an older GLP-1 medication injected daily instead of weekly.
The next Starship launch may come as soon as next week. A test of its Raptor engines suggests SpaceX has resolved the issues that plagued its recent flights.
