  • Wearable knee robot could help children with muscle weakness
    on May 21, 2026 at 6:40 pm

    A lightweight robotic device that facilitates neuromuscular recovery in children with spinal muscular atrophy (SMA), helping them to stand unassisted, is published in Nature this week. Improved function persists after discontinuing training, demonstrating the potential for enduring recovery.

  • Why are young people’s sleep and mental health so poor? Researchers point to ‘vicious cycles’
    on May 21, 2026 at 6:40 pm

    Among the younger part of the population, sleep problems, anxiety, and depression are widespread and growing issues. But why are our sleep and mental health in such poor condition? And why does it seem so difficult to improve the situation?

  • Decoding inflammatory bowel disease—on a chip
    on May 21, 2026 at 6:20 pm

    Inflammatory bowel disease (IBD), which comprises the inflammatory conditions Crohn’s disease and ulcerative colitis, affects about 1.6 million Americans, many of whom cannot be effectively treated. This is mostly due to a lack of understanding of what exactly causes the increased inflammation, fibrosis, and compromised intestinal barrier that underlie this disease and its manifold symptoms, ranging from severe abdominal pain, to diarrhea, weight loss, rectal bleeding and anemia, to anxiety and depression.

  • Implantable tech could cast new light on bladder cancer treatment
    on May 21, 2026 at 6:20 pm

    A new implantable device which aims to maximize the effectiveness of light-sensitive drugs could improve outcomes for bladder cancer patients in the future. Engineers and cancer scientists from the University of Glasgow are behind the development of the device, which uses wirelessly powered micro-LEDs to boost the delivery of light through tissue-mimicking models in the lab. The platform, developed by a team led by Professor David Flynn, is a first step towards a more precise, affordable and comfortable application of photodynamic therapy to treat bladder cancers in the years ahead.

  • The brain’s night shift: How sleep, waste clearance and dementia may be linked
    on May 21, 2026 at 6:00 pm

    Why are conditions such as chronic stress, depression, cardiovascular disease, fragmented sleep, and aging all associated with a higher risk of dementia? In a new review piece in Science, University of Rochester Medicine neuroscientist Maiken Nedergaard, MD, DMSc, proposes that many of these seemingly different conditions may converge on the same biological problem: disruption of a sleep-dependent brain rhythm that helps clear waste from the brain.
