Neanderthals May Have Hunted Giant Elephants that Roamed across Prehistoric Europe
by Enrico de Lazaro on March 16, 2026 at 11:16 pm
Chemical clues preserved in the teeth of straight-tusked elephants (Palaeoloxodon antiquus) from the 125,000-year-old site of Neumark-Nord in Germany suggest these massive animals traveled hundreds […]
New Kind of Planet May Lurk in Milky Way: Extreme World of Magma and Sulfur
by News Staff on March 16, 2026 at 8:25 pm
New observations of L 98-59d, a member of the five-planet system L 98-59, suggest it harbors a vast global magma ocean that traps sulfur deep inside, forming a previously unrecognized class of […]
Tropical Bush Cricket’s Hot-Pink Phase May Be Nature’s Perfect Disguise
by Natali Anderson on March 16, 2026 at 6:31 pm
Entomologists in Panama have observed a leaf-masquerading katydid species that begins life bright pink before turning green days later, a shift that may mimic rainforest leaves that flush red or pink […]
Supergiant Star Makes Rare Leap to Hotter Phase, Astronomers Say
