A surprising vitamin A discovery is changing what scientists know about vision

Scientists at Johns Hopkins University have uncovered a surprising process that helps humans develop sharp vision before birth, challenging decades of assumptions about how the eye forms. Using miniature human retinas grown in the lab, researchers discovered that a vitamin A derivative and thyroid hormones work together to shape the foveola, the tiny region at the center of the retina responsible for our sharpest vision.

Scientists confirm global warming is accelerating faster than ever recorded

Earth is warming faster than ever recorded, with scientists detecting a major acceleration in global temperatures since around 2015. A new study reveals that the warming rate has surged to approximately 0.35°C per decade, nearly double the average pace observed from 1970 to 2015. After removing natural climate fluctuations, researchers confirmed the acceleration with more than 98% statistical confidence.

Earth's ice ages may have been driven by a hidden ocean chain reaction

Scientists have uncovered a surprising connection between Earth's opposite poles that may help explain how the planet plunged into past ice ages. New research suggests that as massive ice sheets expanded across the Northern Hemisphere, they cooled Atlantic Ocean waters that eventually traveled south toward Antarctica. This cooling may have disrupted Southern Ocean circulation, allowing the ocean to absorb and store more carbon dioxide from the atmosphere, further cooling the planet.
