Drug-resistant bacteria are becoming harder to treat, pushing scientists to look for new antibiotic targets. Researchers have now discovered that several unrelated viruses disable a key bacterial protein called MurJ, which is essential for building . ...

Scientists at Texas A&M are turning an everyday pick-me-up into a high-tech medical switch. By combining caffeine with CRISPR gene editing, researchers have created a system that allows cells to be programmed in advance -- and then activated simply . ...

Scientists racing to tackle plastic pollution have created a surprising new contender: a biodegradable packaging film made partly from milk protein. Researchers at Flinders University blended calcium caseinate with starch and natural nanoclay to form ...

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. ...
