  1. Health & Medicine

    Measles in the Americas: Going, going — gone!

    The Americas have at last shed a major childhood scourge: measles. The viral infection used to kill hundreds of children each year. Now the hemisphere only sees cases spread by travelers.

  2. Health & Medicine

    Zika can damage the brains of even adults

    The Zika virus can damage a developing baby’s brain. The infection can also kill off an important type of cells in adult brains, a new mouse study finds.

  3. Health & Medicine

    End of Latin America’s Zika epidemic is in sight

    A computer simulation suggests the Zika epidemic in Latin America is peaking and may not strike hard again for up to three decades.

  4. Health & Medicine

    U.S. mosquitoes now spreading Zika virus

    Scientists had worried that if people sick with Zika came to America, local mosquitoes might bite them and spread the disease. That’s now happened.

  5. 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.

  6. 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.

  7. 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.

  8. 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.

  9. 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.

  10. 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.

  11. 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.

  12. 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.
