  1. Fossils

    Warm feathers may have helped dinos survive mass Triassic die-off

    Dinosaurs may have weathered freezing conditions about 202 million years ago, thanks to warm feathery coats.

  2. Fossils

    This big dino had tiny arms before T. rex made them cool

    A predecessor to Tyrannosaurus rex, Meraxes gigas had a giant head. But the muscularity of its puny arms suggests those limbs served some purpose.

  3. Fossils

    Great white sharks may be partly to blame for the end of megalodons

    Zinc levels in shark teeth hint that megalodons and great whites competed for food — and great whites won.

  4. Fossils

    Bright-colored feathers may have topped pterosaurs’ heads

    Fossil remains of a flying reptile hint that their vibrant crests may have originated 250 million years ago in a common ancestor with dinosaurs.

  5. Oceans

    Night lights make even the seas bright

    Light from coastal cities and offshore development may shine deep enough to disrupt tiny critters living dozens of meters (yards) below the surface.

  6. Environment

    Satellites find big climate threats — ultra-emitters of methane

    Eyes in the sky show many of the worst methane emitters are in countries that produce a lot of oil and gas, such as Russia and the United States.

  7. Climate

    Nuevo informe de la ONU sobre el clima: no hay tiempo que perder

    En el informe de la ONU se vinculan directamente las temperaturas extremas, lluvias e incendios en todo el mundo con el clima cambiante de la Tierra.

  8. Climate

    World’s oceans have warmed to a ‘point of no return’

    More than half the global ocean sees temperature extremes that 100 years ago were rare.

  9. Earth

    The ‘Doomsday’ glacier may soon trigger a dramatic sea-level rise

    The ice shelf that had kept it in place could fail within five years. That would speed the glacier’s slip into the ocean, boosting a rise in sea levels.

  10. Fossils

    Fossils point to earliest dinosaurs that lived in herds

    A fossilized family gathering of long-necked Mussaurus from 193 million years ago is the earliest evidence yet of herd behavior in dinos.

  11. Chemistry

    Chemistry solves a French royal mystery

    Ink analysis reveals the hidden words of Marie Antoinette's letters and who tried to hide them.

  12. Fossils

    Baby pterosaurs may have been able to fly right after hatching

    A bone crucial for lift-off was stronger in hatchling pterosaurs than in adults. The baby reptiles also had shorter, broader wings than grown-ups.
