A fading sense of smell may be one of the earliest warning signs of Alzheimers disease, and new research reveals why. Scientists found that microglia, immune cells in the brain, mistakenly remove nerve fibers connecting ...

Roughly two-thirds of all atmospheric methane, a potent greenhouse gas, comes from methanogens. Tracking down which methanogens in which environment produce methane with a specific isotope signature is difficult, however...

Scientists have uncovered an extinct shelduck from the Chatham Islands that evolved shorter wings and stronger legs, adapting to a predator-free, windy environment. It vanished before the 19th century, likely due to hunt...

Decades of research show that SSRIs can be safely used during pregnancy. Meanwhile, untreated depression during pregnancy is associated with poor health outcomes like preterm birth and preeclampsia.

Astronomers used the James Webb Space Telescope to investigate whether the most distant star identified in the universe is, in fact, a star cluster.

A prominent Nature study and related research raise the possibility that vaccines may have a broader role in experimental therapeutics outside the realm of infectious diseases.

The question of which Roman emperor ruled the longest is tricky to answer.

When a massive 8.8 magnitude earthquake struck off Russias Kamchatka Peninsula, NASA and CNESs SWOT satellite captured a rare and detailed picture of the tsunami that followed. Recorded just over an hour after the quake,...

Scientists have engineered a groundbreaking cancer treatment that uses bacteria to smuggle viruses directly into tumors, bypassing the immune system and delivering a powerful one-two punch against cancer cells. The bacte...

Researchers have synthesized a stable cyclo[48]carbon, a unique 48-carbon ring that can be studied in solution at room temperature, a feat never achieved before.

By flipping a single genetic switch, researchers made one fruit fly species adopt the gift-giving courtship of another, showing how tiny brain rewiring can drive evolutionary change.

After chemotherapy, some people get "chemo curls" and other changes to their hair texture and appearance. But why?

Topological quantum systems are physical systems exhibiting properties that depend on the overall connectivity of their underlying lattice, as opposed to local interactions and their microscopic structure. Predicting the...

NASA and ISRO s NISAR satellite has just reached a major milestone: the successful deployment of its enormous 39-foot antenna reflector in orbit. Folded up like an umbrella during launch, the reflector is now fully exten...

The massive 2025 Myanmar earthquake revealed that strike slip faults can behave in surprising ways. Using satellite data, Caltech researchers found the Sagaing Fault ruptured more dramatically than expected, suggesting f...

Scientists have, for the first time, experimentally proven that angular momentum is conserved even when a single photon splits into two, pushing quantum physics to its most fundamental limits. Using ultra-precise equipme...
