A collaborative team of researchers from the University of California, Berkeley, the Georgia Institute of Technology, and Ajou University in South Koreahas revealed that the unique fan-like propellers of Rhagovelia water striders — which allow them to glide across fast-moving streams — open and close passively, like a paintbrush, ten times faster than the blink…
A new study provides fresh evidence that ancient interbreeding with archaic human species may have provided modern humans with genetic variation that helped them adapt to new environments as they dispersed across the globe. The study, published in Science, focused on a gene known as MUC19, which is involved in the production of proteins that…
The original version of this story appeared in Quanta Magazine. We were once promised self-driving cars and robot maids. Instead, we’ve seen the rise of artificial intelligence systems that can beat us in chess, analyze huge reams of text, and compose sonnets. This has been one of the great surprises of the modern era: physical…
A new discovery of how bees use their flight movements to facilitate remarkably accurate learning and recognition of complex visual patterns could mark a major change in how next-generation AI is developed, according to a University of Sheffield study. iversity of Sheffield built a digital model of a bee’s brain that explains how these movements…
The mystery at Jupiter’s heart has taken a fresh twist – as new research suggests a giant impact may not have been responsible for the formation of its core. It had been thought that a colossal collision with an early planet containing half of Jupiter’s core material could have mixed up the central region of…
Optical microscopy is a key technique for understanding dynamic biological processes in cells, but observing these high-speed cellular dynamics accurately, at high spatial resolution, has long been a formidable task. Now, in an article published in Light: Science & Applications, researchers from The University of Osaka, together with collaborating institutions, have unveiled a cryo-optical microscopy…
A fast radio burst is an immense flash of radio emission that lasts for just a few milliseconds, during which it can momentarily outshine every other radio source in its galaxy. These flares can be so bright that their light can be seen from halfway across the universe, several billion light years away. The sources…
On Mars, the past is written in stone — but the present is written in sand. Last week, Perseverance explored inactive megaripples to learn more about the wind-driven processes that are reshaping the Martian landscape every day. After wrapping up its investigation at the contact between clay and olivine-bearing rocks at “Westport,” Perseverance is journeying…
Weight-loss interventions, including gastric bypass surgery and drugs that prevent dietary fat absorption, can be invasive or have negative side effects. Now, researchers have developed edible microbeads made from green tea polyphenols, vitamin E and seaweed that, when consumed, bind to fats in the gastrointestinal tract. Preliminary results from tests with rats fed high-fat diets…
