A meltwater lake that formed in the mid-1990s on Greenland's 79°N Glacier has been draining in sudden, dramatic bursts through cracks and vertical ice shafts. These events have accelerated in recent years, creating strange triangular fracture ...

A large study has revealed that dozens of widely used chemicals can damage beneficial gut bacteria. Many of these substances, found in pesticides and everyday industrial products, were never thought to affect living organisms at all. When gut ...

A new CRISPR breakthrough shows scientists can turn genes back on without cutting DNA, by removing chemical tags that act like molecular anchors. The work confirms these tags actively silence genes, settling a long-running scientific debate. This ...

CO2 can stimulate plant growth, but only when enough nitrogen is available--and that key ingredient has been seriously miscalculated. A new study finds that natural nitrogen fixation has been overestimated by about 50 percent in major climate models. ...

Researchers have developed experimental compounds that make cells burn more calories by subtly tweaking how mitochondria produce energy. Older versions of these chemicals were once used for weight loss--but were banned for being deadly. The new ...

One of the most complete human ancestor fossils ever found may belong to an entirely new species, according to an international research team. The famous "Little Foot" skeleton from South Africa has long been debated, but new analysis suggests it ...

Scientists have found a way to see ultrafast molecular interactions inside liquids using an extreme laser technique once thought impossible for fluids. When they mixed nearly identical chemicals, one combination behaved strangely--producing less ...

Tiny bits of Earth's atmosphere have been drifting to the moon for billions of years, guided by Earth's magnetic field. Rather than blocking particles, the magnetic field can funnel them along invisible lines that sometimes stretch all the way to the ...

Inside high-energy proton collisions, quarks and gluons briefly form a dense, boiling state before cooling into ordinary particles. Researchers expected this transition to change how disordered the system is, but LHC data tell a different story. A .. ...

Researchers compared a traditional Chinese medicine, Yueju Pill, with a standard antidepressant and found both reduced depression symptoms. However, only Yueju Pill increased a brain-supporting protein associated with mood improvement. Brain imaging ...
