Researchers in Germany have unveiled the Metafiber, a breakthrough device that allows ultra-precise, rapid, and compact control of light focus directly within an optical fiber. Unlike traditional systems that rely on bulky moving parts, the Metafiber uses a tiny 3D nanoprinted hologram on a dual-core fiber to steer light by adjusting power between its cores. This enables seamless, continuous focus shifts over microns with excellent beam quality.

Harvard scientists have uncovered that lithium, a naturally occurring element in the brain, may be the missing piece in understanding Alzheimer’s. Their decade-long research shows that lithium depletion—caused by amyloid plaques binding to it—triggers early brain changes that lead to memory loss. By testing new lithium compounds that evade plaque capture, they reversed Alzheimer’s-like damage and restored memory in mice at doses far lower than those used in psychiatric treatments. Read more ›

Men eating ultra-processed foods gained more fat than those eating unprocessed meals, even with equal calories. Their hormone levels shifted in worrying ways, with testosterone falling and pollutants rising. Researchers say the processing itself, not overeating, is to blame. Read more ›

A Mediterranean diet alone is healthy, but when combined with calorie control, exercise, and support, it cuts type 2 diabetes risk by 31%. The PREDIMED-Plus study followed almost 5,000 participants for six years, making it Europe’s largest nutrition trial. Beyond lowering diabetes risk, participants lost more weight and reduced waist size. Researchers call it clear evidence that small, practical changes can have a big public health impact. Read more ›

Scientists have identified a new giant lizard, Bolg amondol, from Utah’s Kaiparowits Formation, named after Tolkien’s goblin prince. Part of the monstersaur lineage, Bolg reveals that multiple large lizards coexisted with dinosaurs, suggesting a thriving ecosystem. Its discovery in long-stored fossils underscores how museums hold hidden scientific gems. Read more ›

Billions of years ago, Jupiter’s violent growth transformed the young solar system, smashing icy and rocky bodies together at incredible speeds. These cataclysmic collisions created tiny molten droplets called chondrules—microscopic time capsules later preserved in meteorites. New research shows that water vapor explosions from planetesimal impacts explain their origin, while also pinpointing Jupiter’s birth at about 1.8 million years after the solar system began. This breakthrough not only rewrites the... Read more ›

Researchers have developed a blueprint for weaving hopfions—complex, knot-like light structures—into repeating spacetime crystals. By exploiting two-color beams, they can generate ordered chains and lattices with tunable topology, potentially revolutionizing data storage, communications, and photonic processing. Read more ›

Quantum scientists in Innsbruck have taken a major leap toward building the internet of the future. Using a string of calcium ions and finely tuned lasers, they created quantum nodes capable of generating streams of entangled photons with 92% fidelity. This scalable setup could one day link quantum computers across continents, enable unbreakable communication, and even transform timekeeping by powering a global network of optical atomic clocks that are so...

While superconducting qubits are great at fast calculations, they struggle to store information for long periods. A team at Caltech has now developed a clever solution: converting quantum information into sound waves. By using a tiny device that acts like a miniature tuning fork, the researchers were able to extend quantum memory lifetimes up to 30 times longer than before. This breakthrough could pave the way toward practical, scalable quantum... Read more ›
