When researchers moved medaka—a fish commonly used in experiments—out of the lab and into more natural conditions, their reproductive clock shifted by hours, suggesting that laboratory findings may not fully capture their ...

Like fireflies and many deep-sea creatures, certain fungi can naturally emit light through bioluminescence pathways in which specialized enzymes convert chemical energy into visible light. Medical researchers have used fungal ...

Early in development, a group of migrating cells called cranial neural crest cells go on to form many different parts of the face, including the nose, jaw, ears, and throat. To build these structures correctly, genes must ...

While neutrinos are some of the most abundant particles in the universe, they remain among the least understood. One of the biggest puzzles is their mass: although experiments have shown that neutrinos must have some mass, ...

It may sound counterintuitive, but new research suggests that cleaning up air pollution could contribute to a weakening of the Atlantic Meridional Overturning Circulation (AMOC). This is the ocean current system that acts ...

A biotech company that aims to resurrect lost creatures said Tuesday it has hatched live chicks in an artificial environment—a development that was met with mixed reviews from scientists and critics of its de-extinction mission.

Using the MeerKAT radio telescope, an international team of astronomers has discovered 15 new millisecond pulsars in 47 Tucanae—one of the closest and best studied globular clusters. The finding is reported in the latest ...
