  1. Health & Medicine

    Scientists successfully transplant lab-grown lungs into pigs

    Pigs implanted with lab-grown lungs recovered from surgery with no breathing problems.

  2. Genetics

    The first detailed map of red foxes’ DNA may reveal domestication secrets

    Thanks to a newly deciphered genome of red foxes, researchers have pinpointed regions in the animals’ DNA linked to taming them.

  3. Astronomy

    New Horizons may have seen a glow at the solar system’s edge

    New Horizons may have seen a hydrogen wall just past the edge of the solar system, where the solar wind meets the stuff of interstellar space.

  4. Health & Medicine

    Pregnant women’s use of opioids is on the rise

    The rate of opioid use during pregnancy more than quadrupled in 28 U.S. states, prompting physicians to call for increased screening.

  5. Health & Medicine

    The first gene-silencing drug wins FDA approval

    The FDA just approved the first drug that works via RNA interference.

  6. Animals

    In the animal kingdom, what does it mean to be promiscuous?

    A review of hundreds of scientific studies finds that the label “promiscuous” is applied to a surprisingly wide range of mating behaviors in animals.

  7. Computing

    A new computer program generates eerily realistic fake videos

    It’s getting harder to tell fact from fiction — even on camera.

  8. Health & Medicine

    A resurrected gene may protect elephants from cancer

    Researchers have found another gene that may play a role in explaining elephants’ cancer resistance.

  9. Oceans

    Viruses may help phytoplankton make clouds — by tearing the algae apart

    Sick phytoplankton shed their calcium carbonate plates more easily than their healthy counterparts, which could play a role in forming clouds.

  10. Materials Science

    A filter that turns saltwater into freshwater just got an upgrade

    Smoothing out a material used in desalination filters could help combat worldwide water shortages.

  11. Earth

    Scientists create a mineral in the lab that captures carbon dioxide

    Magnesite takes a long time to form in nature. Now, a team has found a way to speed up the making of the mineral, which can store carbon dioxide.

  12. Humans

    Meet the first known child of a Neandertal and a Denisovan

    DNA analysis of a bone fragment reveals Neandertal movements between Siberia and western Europe.

  13. Quantum Physics

    A new quantum device defies the concepts of ‘before’ and ‘after’

    Two events can happen in different orders at the same time, thanks to quantum physics.

  14. Health & Medicine

    50 years ago, a pessimistic view for heart transplants

    Surgeon Christiaan Barnard performed the first successful human-to-human heart transplant in 1967. In 1968, he predicted that patients would survive five years at best. Fortunately, he was wrong.
