• 128,000-year-old ice in Tibet could rewrite climate history

  Ancient ice discovered high in Tibet may be more than 128,000 years old, preserving an extraordinary record of Earth's climate that scientists previously thought had been lost. The discovery reveals a rare glimpse into the last ice age and could reshape our understanding of how glaciers survive dramatic changes in global climate.

• A 700,000-year-old elephant tooth reveals a lost world where early humans lived

  A remarkably preserved elephant tooth dating back nearly 700,000 years has revealed a surprisingly lush prehistoric world where giant elephants and early humans lived side by side. Discovered in northern Israel alongside ancient stone tools, the tooth belonged to a straight-tusked elephant, one of the largest land mammals of the Ice Age.

• Scientists discover a secret glow in toxic fire salamanders

  Researchers have discovered a surprising hidden ability in Europe's familiar black-and-yellow fire salamanders: they glow green and cyan under ultraviolet light. The mysterious fluorescence comes mainly from glands in their skin and their toxic secretions, which can continue glowing for more than 24 hours after being released.

• Scientists discover a hidden oxygen reservoir deep inside Earth

  Scientists have discovered that magma deep inside Earth can store surprising amounts of extra oxygen, potentially revealing a hidden contributor to our planet's oxygen-rich atmosphere. The findings suggest that ancient volcanic eruptions may have helped transform Earth's atmosphere billions of years ago, with implications for understanding life on other planets.

• Antarctica’s “Doomsday Glacier” could raise sea levels twice as much as predicted

  Antarctica’s Thwaites Glacier may be melting twice as much as previously predicted, even without additional global warming. Scientists discovered that warm ocean water is penetrating miles beneath the ice, weakening its foundations and accelerating its retreat. A new model predicts that the glacier could add up to 30 millimeters to global sea levels by 2100, with a 60% chance of losing a crucial stabilizing ridge.
