A missing protein may be aging your immune system
As we age, our immune system quietly loses its edge, and scientists have uncovered a surprising reason why. A protein called platelet factor 4 naturally declines over time, allowing blood stem cells to multiply too freely and drift toward unhealthy, mutation-prone behavior linked to cancer, inflammation, and heart disease. Researchers found that restoring this protein in older mice — and even in human stem cells in the lab — made aging blood and immune cells behave strikingly younger again.

This strange ancient snake was hiding in a museum for decades
A strange little snake fossil found on England’s south coast has finally revealed its secrets—more than 40 years after it was discovered. The newly named Paradoxophidion richardoweni lived around 37 million years ago, during a time when Britain was warmer and teeming with reptiles. Though known only from tiny backbone bones, this “paradox snake” carries a surprising mix of traits seen in modern snakes, placing it near the very roots of today’s most diverse snake group.
