Engineers improve infrared devices using century-old materials
on March 6, 2026 at 12:20 am
After decades of intense research, surprises in the realm of semiconductors—materials used in microchips to control electrical currents—are few and far between. But with a pair of published papers, materials engineers at Stanford University debut a promising approach to using a well-studied semiconductor to improve infrared light-emitting diodes and sensors. They say the approach could lead to smaller, sleeker, and less expensive infrared technologies for environmental, medical, and industrial uses.
AI-designed diffractive optical processors pave the way for low-power structural health monitoring
on March 5, 2026 at 11:30 pm
A team of researchers at the University of California, Los Angeles (UCLA) has introduced a novel framework for monitoring structural vibrations using diffractive optical processors. This new technology uses artificial intelligence to co-optimize a passive diffractive layer and a shallow neural network, allowing the system to encode time-varying mechanical vibrations into distinct spatiotemporal optical patterns.
Making mini-lightning in a block of plastic

Lightning formation and the conditions triggering it have long been shrouded in a cloud of mystery, but new research led by Penn State scientists is lifting the fog. Using mathematical calculations, the researchers have discovered that lightning-like discharge doesn’t require a storm cloud—it could be made inside everyday material on a lab bench. The study is published in the journal Physical Review Letters.
Researchers create a never-before-seen molecule and prove its exotic nature with quantum computing
on March 5, 2026 at 10:50 pm
An international team of scientists from IBM, The University of Manchester, Oxford University, ETH Zurich, EPFL and the University of Regensburg have created and characterized a molecule unlike any previously known—one whose electrons travel through its structure in a corkscrew-like pattern that fundamentally alters its chemical behavior. The work appears in Science.
Why Large Hadron Collider predictions can miss the mark, and a new way to fix it
on March 5, 2026 at 10:30 pm
Estimating things that exist is generally easy, but when it comes to estimating things that do not exist, it’s more difficult. This is something physicists from Poland and the UK are well aware of. To improve current simulations of high-energy particle collisions, they have developed a more accurate method for estimating the impact of calculations that are not performed.
