'Spooky action' at a very short distance: Scientists map out quantum entanglement in protons

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and collaborators have a new way to use data from high-energy particle smashups to peer inside protons. Their approach uses quantum information science to map out how particle tracks streaming from electron-proton collisions are influenced by quantum entanglement inside the proton.

Smallest walking robot makes microscale measurements

Researchers have created the smallest walking robot yet. Its mission: to be tiny enough to interact with waves of visible light and still move independently, so that it can maneuver to specific locations -- in a tissue sample, for instance -- to take images and measure forces at the scale of some of the body's smallest structures.

AI-enhanced satellite carbon monoxide fast retrieval

A recent study presents a radiative transfer model-driven machine learning technique for retrieving carbon monoxide from the world's first hyperspectral Geostationary Interferometric Infrared Sounder (GIIRS) onboard Fengyun-4B (FY-4B) satellite, providing complementary insights into air quality and pollutant transport over East Asia.

Coastal revelations from space: New satellite tech maps sandy beaches

Scientists have developed a method to map sandy beach intertidal zones with unprecedented accuracy using satellite data. This innovative approach allows for precise measurements of coastlines that are constantly shaped by tides and waves, providing crucial information for managing and protecting these dynamic ecosystems.

LPGA commish Mollie Marcoux Samaan stepping down

(Photo credit: Thomas Shea-Imagn Images) LPGA commissioner Mollie Marcoux Samaan will step down on Jan. 9, ending a tenure of unprecedented growth for professional women's golf. Under her leadership since 2021, the LPGA's prize fund increased by more than 90 percent and athlete earnings soared to record highs. Average earnings for the top 100 players nearly doubled from $570,000 in 2021 to more than $1 million in 2024.

'Forever chemicals' are polluting African waters

Every week seems to bring a new report about where "forever chemicals" have been found: in soil, drinking water, our bodies and marine animals. Their proper scientific name is perfluoroalkyl and polyfluoroalkyl substances (PFAS). But they're more commonly called "forever chemicals" because, once they're in an environment, they almost never break down. These chemicals are harmful in many ways: they kill fish, disrupt plant growth and can make humans very ill.
