Scientists at UC Berkeley have discovered a microbe that bends one of biology's most sacred rules. Instead of treating a specific three-letter DNA code as a clear "stop" signal, this methane-producing archaeon sometimes reads it as a green light- ...

Researchers found that cutting two amino acids common in animal protein--methionine and cysteine--made mice burn significantly more energy. The boost in heat production was nearly as powerful as constant exposure to cold temperatures. The mice didn't ...

Astronomers have spotted what may be one of the universe's earliest barred spiral galaxies -- a striking cosmic structure forming just 2 billion years after the Big Bang. The galaxy, COSMOS-74706, dates back about 11.5 billion years and contains a .. ...

Saturn's largest moon, Titan, may have been born in a colossal cosmic crash. New research suggests Titan formed when two older moons slammed together hundreds of millions of years ago--an event so violent it reshaped Saturn's entire moon system and . ...

Researchers at Nagoya University have created a more efficient iron-based photocatalyst that could reduce the need for rare and expensive metals in advanced chemistry. Unlike earlier designs, the new catalyst uses far fewer costly chiral ligands ...

Scientists have unveiled a breakthrough way to turn natural gas--long burned as fuel--into valuable chemical building blocks for medicines and other high-demand products. By designing a clever iron-based catalyst powered by LED light, researchers ...

Scientists at MIT have found compelling chemical evidence that Earth's earliest animals were likely ancient sea sponges. Hidden inside rocks over 541 million years old are rare molecular "fingerprints" that match compounds made by modern demosponges. ...

For decades, scientists believed a fertilized egg's DNA began as a shapeless mass, only organizing itself once the embryo switched on its genes. But new research reveals that the genome is already carefully arranged in three dimensions long before .. ...

Heart disease is on track to tighten its grip on American women. New projections from the American Heart Association warn that over the next 25 years, cardiovascular disease will rise sharply, driven largely by a surge in high blood pressure, ...

Baby dinosaurs weren't coddled like lion cubs or elephant calves--they were more like prehistoric latchkey kids. New research suggests that young dinosaurs quickly struck out on their own, forming kid-only groups and surviving without much parental . ...
