A researcher at a Chengdu university was bitten on the ring finger by a grass-green pitviper from Mount Emei at 22:15 on a September night, the swelling reached his elbow before he reached hospital, and the snake has now been named a species new to science, described partly from museum specimens collected in 1956 and from populations that had been identified as a more widespread relative on their looks alone
Scientists thought Titan was hiding a global ocean beneath its frozen crust. But a 2025 reanalysis of Cassini data points to something stranger instead — a roughly 380-kilometre-thick layer of slushy ice, close to melting and likely threaded with pockets of liquid water that could reach 20°C near the rocky interior.
