    Scientists unlock a powerful new way to turn sunlight into fuel
    16/03/26 09:01:39
    Scientists have developed a powerful new computational method that could accelerate the search for next-generation materials capable of turning sunlight into useful chemical energy. The work focuses on polyheptazine imides, a promising class of carbon nitride materials that absorb visible light and can drive reactions such as hydrogen production, carbon dioxide conversion, and hydrogen peroxide synthesis. By analyzing how 53 different metal ions influence the structure and electronic behavior of these materials, researchers created a framework that predicts which combinations will perform best.

    Life rebounded shockingly fast after the asteroid that killed the dinosaurs
    15/03/26 05:44:14
    The asteroid impact that wiped out the dinosaurs didn’t keep life down for long. New research shows that microscopic plankton began evolving into new species within just a few thousand years—and possibly in under 2,000 years—after the disaster. Scientists uncovered this rapid rebound by using a rare isotope marker to more accurately measure time in ancient sediments. The discovery suggests life recovered far faster than previously thought.

    Scientists just discovered a tiny signal that volcanoes send before they erupt
    16/03/26 00:51:35
    A new detection method called “Jerk” could dramatically improve how scientists forecast volcanic eruptions. By using a single broadband seismometer, the system can detect extremely subtle ground movements caused by magma pushing underground—often hours before an eruption begins. Tested for more than a decade at the Piton de la Fournaise volcano on La Réunion, the tool successfully predicted 92% of eruptions between 2014 and 2023, sometimes giving up to eight hours of warning.

    Millions of kids take melatonin but doctors are raising red flags
    15/03/26 12:08:26
    Melatonin is now widely used to help children sleep, but scientists say the enthusiasm may be getting ahead of the evidence. A major review found clear benefits for children with conditions like autism and ADHD, yet far less data exists for typical childhood insomnia. Researchers also warn about mislabeled supplement doses and rising accidental ingestions among young kids. Experts say melatonin should be used carefully and only alongside proven behavioral sleep strategies.

    MIT scientists discover gut protein that traps and kills dangerous bacteria
    16/03/26 05:05:04
    Scientists at MIT have discovered that a little-known protein called intelectin-2 plays a powerful double role in defending the gut. The protein strengthens the mucus layer that lines the gastrointestinal tract while also trapping and disabling harmful bacteria that try to break through. By binding to sugars on both mucus molecules and bacterial surfaces, intelectin-2 forms a protective barrier and can even destroy microbes, including some that resist antibiotics.
