The shocking origin of human eyes traces back to an ancient “cyclops”

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 100 million-year-old snake had hind legs and a lost bone that changes evolution

Nearly 100 million years ago, snakes weren’t the sleek, limbless creatures we know today—they still had hind legs and even a cheekbone that has almost vanished in modern species. A remarkably preserved fossil of Najash rionegrina from Argentina has reshaped how scientists think about snake origins, suggesting early snakes were large, wide-mouthed predators rather than tiny burrowers.

Two common drugs may reverse fatty liver disease, study finds

Scientists have discovered that combining two existing drugs can dramatically reduce liver fat linked to a common and often silent disease. The treatment not only improved liver health in animal models but also showed potential to lower heart-related risks. Interestingly, using lower doses of both drugs together worked just as well as higher doses alone. While promising, the findings still need to be tested in humans.
