    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.
    Astronomers just found the source of the brightest fast radio burst ever
    15/03/26 11:57:42
    Astronomers have discovered the brightest fast radio burst ever detected and traced it to a nearby galaxy using a new network of CHIME Outrigger telescopes. The flash, nicknamed RBFLOAT, lasted only a fraction of a second but briefly outshone every other radio source in its galaxy. Follow-up observations with the James Webb Space Telescope spotted a faint infrared signal at the same location. The burst’s unusual behavior—showing no signs of repeating—may challenge current ideas about what causes these mysterious cosmic flashes.
    Scientists discover hidden water beneath Mars that could have supported life
    15/03/26 11:45:30
    New research suggests Mars may have remained habitable much longer than scientists once thought. Ancient sand dunes in Gale Crater appear to have been soaked by underground water billions of years ago, leaving behind minerals that can preserve signs of life. Even after surface water disappeared, subsurface flows may have created protected environments for microbes. These hidden habitats could be key targets in the ongoing search for past life on Mars.
    Scientists tested vitamin D for COVID and found an unexpected long COVID clue
    15/03/26 10:54:54
    A major clinical trial has delivered an unexpected twist in the search for ways to fight COVID-19 and its lingering effects. Researchers at Mass General Brigham found that taking high doses of vitamin D3 did not make COVID-19 infections less severe or reduce hospital visits. However, the study uncovered a subtle but intriguing signal suggesting that people who consistently took vitamin D supplements might be slightly less likely to develop long COVID symptoms weeks after infection.
    Fathers’ tobacco use linked to metabolic changes in their children
    15/03/26 06:42:15
    A new study in mice suggests that a father’s nicotine exposure could influence the metabolic health of his children. Researchers found that when male mice consumed nicotine, their offspring showed changes in how their bodies handled sugar, including differences in insulin and glucose levels and altered liver function. These shifts may be linked to a higher risk of diabetes and related metabolic diseases.
