Cedars-Sinai researchers created “young” immune cells from human stem cells that reversed cognitive decline and Alzheimer’s symptoms in mice. The treated animals showed better memory and healthier brain structures. The cells seemed to protect the brain indirectly, possibly through anti-aging signals in the blood. The findings suggest a new, personalized path to slowing brain aging.
A chance encounter with plastic waste on a tropical beach sparked a deep investigation into what those fragments mean for human health. The research reveals that bottled water isn’t as pure as it seems—each sip may contain invisible microplastics that can slip through the body’s defenses and lodge in vital organs. These tiny pollutants are linked to inflammation, hormonal disruption, and even neurological damage, yet remain dangerously understudied.
Astronomers have found the most distant and energetic “odd radio circle” ever detected — a massive double-ringed radio structure nearly 10 billion years old. The discovery, made with the help of citizen scientists using LOFAR, challenges theories that these cosmic rings are caused by black hole mergers. Instead, researchers suggest galactic superwinds may be to blame.
Scientists have confirmed that the Atlas blue butterfly carries the most chromosomes of any animal, with 229 pairs. Unlike duplication, its chromosomes split apart, reshaping its genome in surprising ways. This discovery sheds light on evolution, conservation, and even cancer research.
Salk scientists uncover a key neural circuit in mice that gives pain its emotional punch, opening new doors for treating fibromyalgia, migraine, and PTSD—without addictive medications.
A team of scientists has identified specialized neurons in the brain that store “meal memories” detailed recollections of when and what we eat. These engrams, found in the ventral hippocampus, help regulate eating behavior by communicating with hunger-related areas of the brain. When these memory traces are impaired due to distraction, brain injury, or memory disorders individuals are more likely to overeat because they can’t recall recent meals. The research not only uncovers a critical neural mechanism but also suggests new strategies for treating obesity by enhancing memory around food consumption.
The giant cat roamed North America 5-9 million years ago, weighing up to 900 pounds and hunting prey that likely weighed 1,000 to 2,000 pounds, scientists reported in a new study.
A meta-analysis finds that vision impairment and blindness are tied to an increased risk of mortality, prompting the need to address global eye health disparities.
