    The shocking origin of human eyes traces back to an ancient “cyclops”
    27/04/26 10:31:43
    A bizarre, cyclops-like creature from nearly 600 million years ago may hold the key to how your eyes—and even your sleep cycle—evolved. Scientists have discovered that all vertebrates, including humans, trace their vision back to a single light-sensitive “median eye” perched atop a worm-like ancestor’s head. As this ancient animal shifted from a sedentary to a more active lifestyle, it lost and then reinvented its vision, eventually giving rise to the paired, image-forming eyes we rely on today.
    This one change to your exercise routine could add years to your life
    27/04/26 07:32:16
    Mixing up your workouts might be the real secret to a longer life. Long-term research tracking over 100,000 people for more than three decades suggests that doing a variety of physical activities—rather than just more of the same—can significantly lower the risk of death. Interestingly, the benefits don’t keep rising endlessly; they seem to level off after a certain point, hinting at a “sweet spot” of activity.
    Fish oil may be hurting your brain, new study finds
    26/04/26 07:57:51
    Fish oil has long been praised as brain-boosting, but new research suggests the story may be more complicated. Scientists found that in people with repeated mild head injuries, a key omega-3 fatty acid in fish oil—EPA—may actually interfere with the brain’s ability to repair itself. Instead of helping recovery, it appears to weaken blood vessel stability, disrupt healing signals, and even contribute to harmful protein buildup linked to cognitive decline.
    Blood vessels found in T. rex bones are rewriting dinosaur science
    26/04/26 13:44:57
    Dinosaur DNA may still be out of reach, but scientists are uncovering something almost as exciting—ancient blood vessels hidden inside fossilized bones. In a massive Tyrannosaurus rex nicknamed Scotty, researchers discovered a network of preserved vessels within a rib that once fractured and began healing 66 million years ago. Using powerful synchrotron X-rays from particle accelerators, they were able to peer inside the dense fossil without damaging it, revealing intricate, iron-rich structures left behind by the healing process.
    DNA research just rewrote the origin of human species
    26/04/26 12:53:10
    Scientists have uncovered a surprising new picture of human origins that challenges the long-held idea of a single ancestral population in Africa. By analyzing genetic data from diverse modern African groups—especially the highly distinct Nama people—and comparing it with fossil evidence, researchers found that early humans likely evolved from multiple intermingling populations over hundreds of thousands of years. Rather than a clean split, these groups stayed connected, exchanging genes even after beginning to diverge around 120,000–135,000 years ago.
