What would Bill Nye the Science Guy get our home planet for Earth Day? The ultimate gift: fusion energy. “We need electricity,” Nye told Live Science in an exclusive interview on Thursday (April 20). “We need not only what we can get right now with existing technologies — with wind, and solar and geothermal energy … Read more
Our “biological age,” which reflects signs of age-related decline in our cells and tissues, doesn’t steadily increase along with our chronological age. Instead, new research suggests that biological aging can accelerate during stressful events and then reverse after those events. In other words, there are measurable biological markers linked to age-related changes in cell function, … Read more
The spread of drug-resistant “superbugs” — including bacteria that have evolved to thwart even the most potent antibiotics — represents an ever-growing threat to public health. Now, scientists have invented a new type of antibiotic that can take down these germs by rapidly rearranging its atoms and thus changing its shape. The researchers described the … Read more
Human beings can generate false memories of events mere seconds after they have occurred, a new study has found. The phenomenon, which researchers have dubbed “short-term memory illusions,” shows how easily and rapidly humans reimagine experiences to fit our preconceptions, rather than accurately recording what takes place. The researchers published their findings April 5 in … Read more
Scientists have long debated the greatest possible age of a person, with previous studies placing the limit at up to 150 years. But in the past 25 years, no one has surpassed the record for the world’s oldest person, held by Jean Louise Calment, who died at age 122 in 1997. “This has led people … Read more
Chinese researchers may have discovered billions of tons of water inside strange glass spheres buried on the moon, and they could be used as a future water source for moon bases, a new study suggests. The tiny glass spherules, collected in lunar soil samples and brought to Earth by China’s Chang’e-5 mission in December 2020, … Read more
A person’s native language may shape how their brain builds connections between different hubs of information processing, a new brain scan study reveals. The observed differences in these language network structures were related to linguistic characteristics in the native languages of the study participants: German and Arabic. “So the difference we find there shouldn’t be … Read more
Scientists studying a cousin of the bacteria responsible for tuberculosis and leprosy have discovered an enzyme that converts hydrogen into electricity, and they think it could be used to create a new, clean source of energy literally from thin air. The enzyme, which has been named Huc, is used by the bacterium Mycobacterium smegmatis to … Read more
A sea creature mentioned in 13th-century Old Norse manuscripts, which historians thought was a kraken-like mythological monster, is actually a whale using a hunting strategy known as trap or tread-water feeding, a new study finds. Scientists only described this feeding behavior around a decade ago, after they spotted humpback whales (Megaptera novaeangliae) and Bryde’s whales … Read more
Miniature, lab-grown models of the human brain’s wrinkled surface can be used to patch injuries in the brains of living rats and thus repair broken connections in the rodents’ sensory processing systems, a new study shows. Someday, such minibrains — known as brain organoids — could potentially be used to mend the brains of human … Read more
