  • A lab mistake at Cambridge reveals a powerful new way to modify drug molecules
    Cambridge scientists have discovered a light-powered chemical reaction that lets researchers modify complex drug molecules at the final stages of development. Unlike traditional methods that rely on toxic chemicals and harsh conditions, the new approach uses an LED lamp to create essential carbon–carbon bonds under mild conditions. This could make drug discovery faster and more […]
  • Scientists just found a way to 3D print one of the hardest metals on Earth
    Scientists have found a promising new way to manufacture one of industry’s toughest materials—tungsten carbide–cobalt—using advanced 3D printing. Normally, producing this ultra-hard material requires high-pressure processes that waste large amounts of expensive tungsten and cobalt. The new approach uses a hot-wire laser technique that softens the metals rather than fully melting them, allowing manufacturers to […]
  • Scientists turn scrap car aluminum into high-performance metal for new vehicles
    Scientists at Oak Ridge National Laboratory have created a new aluminum alloy called RidgeAlloy that can turn contaminated car-body scrap into strong structural vehicle parts. Normally, impurities introduced during recycling make this scrap unsuitable for high-performance applications. RidgeAlloy overcomes that challenge, enabling recycled aluminum to meet the strength and durability standards required for modern vehicles. […]
  • Electrons catapult across solar materials in just 18 femtoseconds
    Electrons in solar materials can be launched across molecules almost as fast as nature allows, thanks to tiny atomic vibrations acting like a “molecular catapult.” In experiments lasting just 18 femtoseconds, researchers at the University of Cambridge observed electrons blasting across a boundary in a single burst, far faster than long-standing theories predicted. Instead of […]
  • Record-breaking photodetector captures light in just 125 picoseconds
    A new ultrathin photodetector from Duke University can sense light across the entire electromagnetic spectrum and generate a signal in just 125 picoseconds, making it the fastest pyroelectric detector ever built. The breakthrough could power next-generation multispectral cameras used in medicine, agriculture, and space-based sensing.
  • For the first time, light mimics a Nobel Prize quantum effect
    Scientists have pulled off a feat long considered out of reach: getting light to mimic the famous quantum Hall effect. In their experiment, photons drift sideways in perfectly defined, quantized steps—just like electrons do in powerful magnetic fields. Because these steps depend only on nature’s fundamental constants, they could become a new gold standard for […]
