The human body and its gut microbiome produce thousands of small molecules that shape how the body functions—influencing immunity, metabolism and more. Identifying what those molecules actually are has been one of the biomedical ...

Europe is no stranger to powerful windstorms, but some storms capable of causing serious damage have an unusual origin. Tropical cyclones can occasionally travel north from lower latitudes and reach Europe, where they can ...

All known life on Earth uses the same genetic alphabet, consisting of four letters. Now, researchers at the University of California San Diego have demonstrated that one of biology's most essential enzymes can accurately ...

When researchers at HHMI's Janelia Research Campus set out to create a map of all the neurons in the fruit fly brain in 2008, many in the scientific community thought they were out of their minds.

Detecting radiation is key to technologies ranging from particle accelerators and scientific instruments to medical imaging and security screening. But current detectors must often make trade-offs, providing signals that ...

Narwhals have nature's only straight tusk, a single tooth up to three meters (10 feet) long, so strange they were sold as magical unicorn horns during the Middle Ages.

Researchers at the University of Oslo and Oslo University Hospital, together with international collaborators, have discovered that a small molecule made exclusively by gut bacteria can actively drive disease in the bile ...

The poet Dylan Thomas famously wrote, "old age should burn and rave at close of day"—and a high-profile cohort of professional athletes seems to be taking him literally.

Has El Niño reached the West Coast? You might think it has. After all, the ocean off Southern and Central California is unusually warm. But that warmth is from a recent marine heat wave that predates the current El Niño. ...

Astronomers may have finally solved the mystery behind a nearly two-decade-old cosmic explosion that seemed to break the rules of physics. The energy output of a powerful gamma-ray burst, GRB 061201, discovered in 2006, did ...

A private spacecraft that was supposed to provide a lifeline to NASA's Swift Observatory managed to get close to the sinking telescope and even snap photos two weeks after the rescue was abandoned.

The neuroactive potential of bacteria living in the human gut is associated with levels of key chemicals in the brain, according to a new study published in Molecular Psychiatry. The research team from the University of Surrey ...
