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.

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.
With the active ingredients in drugs like Ozempic and Zepbound no longer in shortage, access to medicine for millions who had come to rely on compounded versions is increasingly uncertain.
The agency maintains the global backbone of measurements of CO2 and other gases, but these are at risk of being curtailed if the foreshadowed cuts to NOAA are realized.
Casey Means isn’t currently licensed as a doctor. But that’s not why anti-vaxxers and conspiracists think she’s unsuited to be surgeon general—to them, her anti-vaccine opinions aren't extreme enough.
CBP’s acting commissioner has rescinded four Biden-era policies that aimed to protect vulnerable people in the agency’s custody, including mothers, infants, and the elderly.
The Choose Europe for Science program will invest more than half a billion dollars between 2025 and 2027 to recruit researchers and scientists—especially from the United States.
Stratolaunch completed two flights of its autonomous Talon-A2 rocket plane earlier this year, as the US aims to gain ground in its race for hypersonic supremacy with China.
