A Manhattan-sized ice island just broke free from Greenland
A huge section of Greenland’s Petermann Glacier has snapped off, forming an ice island about the size of Manhattan. Satellites watched cracks spread rapidly before …
Atomic catalyst unlocks the hidden value of plant waste
Scientists have created a highly efficient catalyst that breaks down stubborn lignin from plant waste into useful chemicals under relatively mild conditions. By revealing exactly …
Scientists find hidden “highways” guiding animal evolution
A sweeping analysis of thousands of animal genomes suggests that chromosomes do not evolve randomly but instead follow a limited number of irreversible “evolutionary highways.” …
NASA finds Earth microbes could survive on the Moon
NASA scientists found that microbes brought by astronauts could survive in cold, shadowed niches around the Moon’s South Pole, potentially complicating future searches for pristine …
Depression may shut down the brain’s ability to make new neurons
A major study found that adults with depression show disrupted production of new neurons in the hippocampus, potentially weakening the brain’s ability to separate new …
