A leftover from microbes’ meals is linked to early heart disease in people. In mice, it contributed to plaque buildup in the arteries.

Quantum computers in space could be useful for communications networks or for testing fundamental physics.

Research based on game theory suggests if we program AI agents with a sense of guilt, they could behave more cooperatively, much like humans do.

An infinity symbol–shaped galaxy hosts an active supermassive black hole. The growing giant may have come from the aftermath of a galactic smashup.

A fish thought to be evolution’s time capsule just surprised scientists. A detailed dissection of the coelacanth — a 400-million-year-old species often called a “living fossil” — revealed that key muscles believed to be part of early vertebrate evolution were actually misidentified ligaments. This means foundational assumptions about how vertebrates, including humans, evolved to eat and breathe may need to be rewritten. The discovery corrects decades of anatomical errors, reshapes the story of skull evolution, and brings unexpected insights into our own distant origins.

Studies suggest that people who had seasonal flus or vaccinations have low antibody levels against H5N1 bird flu.

An Australian zoo has recruited a puppy to help socialise a precious cheetah cub after she had to be separated from her mother, and the two have become firm friends

Seeing sick-looking faces in virtual reality triggers brain circuit changes related to threat detection and boosts activity of certain immune cells.

Drone footage from Norway shows killer whales using a highly coordinated and cooperative hunting technique to catch herring.

Maggots on rotting meat may have given Neandertals’ a fatty, nitrogen-rich boost, a study of their bones suggests.

After a sprint, the temperature of the beetle Onymacris plana drops. Efficient running, a body built for cooling and a little bit of lift all help.

A team used generative AI to enhance T cells’ ability to fight melanoma. The immunotherapy approach needs more testing before use in cancer patients.

An algal bloom in South Australia has caused mass deaths of many species since March - now researchers warn that leafy and weedy seadragons could be facing the threat of extinction

GLP-1 drugs for diabetes and weight loss are difficult for some people to inject weekly. A new slow-release gel, tested in rats, could help.

A century-old fossil long mislabeled as a caterpillar has been reidentified as the first-known nonmarine lobopodian—rewriting what we know about ancient life. Discovered in Harvard’s museum drawers, Palaeocampa anthrax predates even the famous Cambrian lobopodians and reveals that these soft-bodied ancestors of arthropods once lived not only in oceans, but in freshwater environments too.

A tiny, overlooked wrist bone called the pisiform may have played a pivotal role in bird flight and it turns out it evolved far earlier than scientists thought. Fossils from bird-like dinosaurs in Mongolia reveal that this bone, once thought to vanish and reappear, was actually hiding in plain sight. Thanks to pristine preservation and 3D scans, researchers connected the dots between ancient theropods and modern birds, uncovering a deeper, more intricate story of how dinosaurs evolved the tools for powered flight.
