Scientists have identified a hidden feedback loop that may explain how Earth has regulated its climate for tens of millions of years. As sea levels rose and fell, they changed how much phosphate reached the open ocean, affecting marine life and the . ...

A distant Sun-like star appears to have devoured one of its planets, leaving behind a surprising chemical fingerprint. Researchers found an unusually high concentration of lithium, a strong sign that planetary material was mixed into the star. ...

A powerful new AI tool has uncovered what could be one of the biggest integrity problems in modern science. After analyzing 2.6 million cancer research papers published between 1999 and 2024, researchers identified more than 250,000 studies with ...

Researchers solved a long-standing mystery behind how a bacterial toxin associated with colorectal cancer damages the colon. The toxin first binds to a receptor called claudin-4, giving it access to attack the cells' protective barrier. After ...

A growing Cyclospora outbreak has sickened more than 400 people in four states, and investigators are still searching for the contaminated food responsible. The CDC warns the actual number of cases is likely much higher and urges anyone with symptoms ...

A new review highlights exciting progress in atomically thin quantum materials where light and magnetism work together in ways never before possible. In these materials, light-generated excitons can interact directly with magnetic behavior, creating ...

NASA's James Webb Space Telescope has revealed new details about the blistering lava planet 55 Cancri e, where temperatures are high enough to melt rock. The data indicate the planet likely has a hydrogen-rich atmosphere shaped by gases escaping from ...

An existing constipation drug may have an unexpected new use: helping clear the "brain fog" that often lingers after depression. In a small clinical trial, people with a history of depression who took the medication prucalopride for about a week ...

Researchers have discovered that a microscopic skeleton inside neurons does much more than hold cells together. It acts as a gatekeeper that controls what brain cells absorb and when they absorb it. When this protective structure weakens, neurons ...

An unusual leopard gecko that naturally develops aggressive tumors may become an important new model for cancer research. Scientists found its tumors share key genetic changes with human cancers, offering a rare opportunity to study the disease as it ...
