Scientists have used light to visualize magnetic domains, and manipulated these regions using an electric field, in a quantum antiferromagnet. This method allows real-time observation of magnetic behaviors, paving the way for advancements in next-generation electronics and memory devices, as well as a deeper understanding of quantum materials. When something draws us in like a

When lightning cracks on Earth, especially high-energy electrons may fall out of Earth's inner radiation belt, according to a new study -- an electron 'rain' that could threaten satellites, and even humans, in orbit. When lightning strikes, the electrons come pouring down. In a new study, researchers at the University of Colorado Boulder led by

An organic catalyst offers chemists precise control over a vital step in activating hydrocarbons. An organic catalyst offers chemists precise control over a vital step in activating hydrocarbons. Researchers at Hokkaido University in Japan have made a significant breakthrough in organic chemistry by developing a novel method to activate alkanes, which are compounds that play

Researchers have significantly improved a new joining technology, interlocking metasurfaces (ILMs), designed to increase the strength and stability of a structure in comparison to traditional techniques like bolts and adhesives, using shape memory alloys (SMAs). ILMs offer the potential to transform mechanical joint design in manufacturing for aerospace, robotics and biomedical devices. In a collaborative

Artificial Intelligence has learned to master language, generate art, and even beat grandmasters at chess. But can it crack the code of abstract reasoning --t hose tricky visual puzzles that leave humans scratching their heads? Researchers are putting AI's cognitive abilities to the test, pushing the multi-modal large language models (MLLMs) to solve visual problems

Scientists are using mechanisms inspired by nature to create new technological innovations. A team has now created an octopus-inspired adhesive, inspired by the shape of octopus suckers, that can quickly grab and controllably release challenging underwater objects. Having the ability to grab and release these underwater objects like heavy rocks, small shells, and soft beads

Chirality -- a geometric property that allows molecules to exist in two distinct forms that are chemically identical but are 3D mirror images of each other, like a right and left hand -- has a powerful effect on nuclear spin state but was thought to have no effect on coupling between spins. A study found

Micelles play a crucial role in dispersing hydrophobic inks and drug in water-based solutions. Recently, researchers compared the dye solubilization capacities of micelles made from block and random copolymers to identify the optimal structure for dye solubilization. Their results show that block copolymer micelles with well-defined core-shell structures have a slower solubilization rate but can

Researchers devised a way to expand tissue 20-fold in a single step. Their simple, inexpensive method could pave the way for nearly any biology lab to perform nanoscale imaging. A classical way to image nanoscale structures in cells is with high-powered, expensive super-resolution microscopes. As an alternative, MIT researchers have developed a way to expand

For decades, scientists knew there was a huge swath of undetected and unaccounted for per- and polyfluoroalkyl substances (PFAS) in the atmosphere, often referred to as PFAS dark matter, but no one knew how much was missing or how to measure them. Now, an atmospheric chemistry research team has devised a way to test for

A new technique enables makers to finely tune the color, shade, and texture of 3D-printed objects using only one material. The method is faster and uses less material than other approaches. Multimaterial 3D printing enables makers to fabricate customized devices with multiple colors and varied textures. But the process can be time-consuming and wasteful because
