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…
