In science fiction films, nothing raises tension quite like the good guys’ spaceship getting caught in an invisible tractor beam that allows the baddies to slowly reel them in. But what was once only a sci-fi staple could soon become a reality. Scientists are developing a real-life tractor beam, dubbed an electrostatic tractor. This tractor … Read more
It’s long been assumed that men were hunters and women were gatherers, but a new study reveals that both sexes have been equally adept at hunting in hunter-gatherer cultures. An international team of scientists made the finding after examining data culled from dozens of academic papers, published over the past 100 years, that focused on … Read more
Earth is being choked by a thick, curling fog of carbon dioxide that coats the planet as the months go by, a series of NASA videos shows. The newly released animations visualize the astonishing scale of human carbon dioxide (CO2) emissions over a year by coloring the invisible greenhouse gas. The animations were produced by … Read more
Neanderthal genes may be one cause of the disorder nicknamed the “Viking disease,” in which fingers become frozen in a bent position, a new study finds. The study, published June 14 in the journal Molecular Biology and Evolution, finds gene variants that were inherited from Neanderthals that dramatically increase the odds of developing the condition, … Read more
Mysterious, spiral signals have been discovered in the human brain, and the scientists who found the swirls think they could help to organize complex brain activity. The signals, which appeared as swirling spirals of brain waves across the outer layer of the brain, were discovered in functional magnetic resonance imaging (fMRI) brain scans of 100 … Read more
Fish are constantly surrounded by water, but do they get thirsty? And how would they even drink? To answer these question, it’s crucial to understand how water — a solvent — interacts with other substances like salt, which is a solute, across a cell membrane. Through a process called osmosis, water flows across a membrane … Read more
Quantum computers could beat classical ones at answering practical questions within two years, a new experiment from IBM computers shows. The demonstration hints that true quantum supremacy, in which quantum computers overtake classical digital ones, could be here surprisingly soon. “These machines are coming,” Sabrina Maniscalco, CEO of Helsinki-based quantum-computing startup Algorithmiq, told Nature News. … Read more
Archaeologists in Germany have unearthed a sword from a Bronze Age burial, and the weapon is in such good condition that it still gleams. The 3,000-year-old sword, discovered in the town of Nördlingen in Bavaria, was found in the burial of a man, woman and child. It appears that the trio were buried in quick … Read more
Two children who experienced intense, insatiable hunger that drove them to overeat have rare, never-before-seen genetic mutations that interfere with leptin, a key hormone that helps tell the body when it is full, a new case report says. After white fat cells make leptin, it plugs into the brainstem and hypothalamus, brain regions that help … Read more
A method for “reanimating” organ donors’ hearts works just as well as the standard approach to collecting hearts for transplantation, new trial data shows. If widely applied, the method could increase the heart donor pool by an estimated 30%. “Honestly if we could snap our fingers and just get people to use this, I think … Read more
