926 New light trap design supercharges atom-thin semiconductors

ScienceDaily
ScienceDaily · 03/24/2026 03:25 EDT

Scientists have found a clever way to supercharge ultra-thin semiconductors by reshaping the space beneath them rather than altering the material itself. By placing a single-atom-thick layer of tungsten disulfide over tiny air cavities carved into a crystal, they created miniature “light traps” that dramatically boost brightness and optical effects—up to 20 times stronger emission and 25 times stronger nonlinear signals. These hollow structures, called Mie voids, concentrate light exactly where the material

Your brain’s “stop eating” signal may come from an unexpected source. Researchers found that astrocytes—once thought to just support neurons—actually play a key role in controlling appetite. After a meal, glucose triggers tanycytes, which send signals to astrocytes that then activate fullness neurons. This newly discovered pathway could lead to innovative treatments for obesity and eating disorders. Read more

Earth may have won a cosmic chemistry lottery. Researchers found that during the planet’s earliest formation, oxygen had to be in an extremely narrow “Goldilocks zone” for two life-essential elements, phosphorus and nitrogen, to stay where life could use them. Too much or too little oxygen, and those ingredients could be lost or trapped deep inside the planet. This could reshape the search for life by showing that water alone... Read more

A remarkable fossil discovery in southwest China is rewriting the story of how complex animal life began, showing that many key animal groups appeared millions of years earlier than scientists once believed.

A colossal ocean current encircling Antarctica—stronger than all the world’s rivers combined—played a far more complex role in shaping Earth’s climate than scientists once thought. New research shows it didn’t form just because ocean gateways opened, but required shifting continents and powerful winds to align. This shift helped pull carbon dioxide out of the atmosphere, contributing to a major cooling event that transformed Earth into the ice-covered world we know... Read more

These proteins appear to disable a key “weapon” the bacteria use... Read more
