  1. Fossils

    Parasites wormed their way into dino’s gut

    Tiny burrows crisscross the stomach of a 77-million-year-old dinosaur fossil. These may be tracks left behind by slimy parasitic worms.

  2. Science & Society

    Strict gun laws ended mass shootings in Australia

    Australia enacted tough gun laws in 1996, which cut gun exposure — especially to semiautomatic weapons. Since then, new data show, that nation has experienced zero mass shootings.

  3. Health & Medicine

    Zika vaccines look promising

    As a Zika epidemic surges through Brazil and northward, scientists are looking for drugs to keep more people from becoming infected. Several vaccines show promise in early tests — but none has yet been tried in people.

  4. Brain

    Mapping word meanings in the brain

    A detailed new map shows that people comprehend words by using regions across the brain, not just in one dedicated language center.

  5. Fossils

    Baby titanosaur was a mini version of its parents

    Fossils show that baby titanosaurs looked like mom and dad. They may have been active and independent from a young age.

  6. Fossils

    How to tell if a T. rex is expecting

    A chemical test of tyrannosaur bone can determine whether the dino was pregnant — and therefore a female.

  7. Health & Medicine

    Scientists link Zika to nerve disease

    The Zika virus is spreading in the Americas. There has also been an uptick in cases of Guillain-Barré syndrome. Scientists think the two are linked.

  8. Microbes

    Missing gut bacteria linked to poor nutrition in children

    The right mix of microbes in the gut could help prevent — or treat — malnutrition in children.

  9. Health & Medicine

    Flexible electronics track sweat

    A flexible, wireless health monitor that can wrap around the wrist tracks temperature and analyzes sweat to detect signs of too much water loss.

  10. Health & Medicine

    Zika worries go global

    The World Health Organization says the devastating birth defects and brain disorders linked to the Zika virus are an international health emergency.

  11. Health & Medicine

    Zika virus raises alarm as it spreads in the Americas

    Zika virus has been in Africa and Asia for decades. But is has now spread to the Americas. And it may cause a devastating birth defect.

  12. Earth

    Bubbles may have sheltered Earth’s early life

    For Earth’s earliest inhabitants, a bubble on the beach would have been the next best thing to a safety blanket.
