1. Genetics

    50 years ago, chimeras gave a glimpse of gene editing’s future

    Advances in gene editing technology have led to the first successful transplant of a pig kidney into a human.

  2. Particle Physics

    Scientists propose a hunt for never-before-seen ‘tauonium’ atoms 

    Made of heavy relatives of the electron, the exotic atoms could be used to test the theory of quantum electrodynamics.

  3. Health & Medicine

    50 years ago, phantom pain was blamed on misfiring nerves 

    Researchers now know that the cause of post-amputation pain is more complex, which is leading to new treatments.

  4. Animals

    Getting wild mosquitoes back to the lab alive takes a custom backpack

    The new low-tech transportation method could help scientists in Africa assess if malaria-carrying mosquitoes are resistant to a common insecticide.

  5. Health & Medicine

    50 years ago, margarine’s ‘healthy’ reputation began to melt away

    In the 1970s, scientists began to suspect that margarine was bad for heart health. A key component, artificial trans fat, was a major factor.

  6. Animals

    50 years ago, scientists wondered how birds find their way home

    In the 1970s, lab tests hinted that birds can navigate using magnetic fields. New studies suggest that beak and eye proteins are behind the ability.

  7. Space

    50 years ago, scientists found a lunar rock nearly as old as the moon

    Studies of such rocks continue to reveal secrets about the moon’s history.

  8. Physics

    50 years ago, superconductors were warming up

    Superconducting temperatures have risen by about 250 degrees since the 1970s, but are still too cold to enable practical technologies.

  9. Health & Medicine

    50 years ago, computers helped speed up drug discovery

    In 1974, a computer program helped researchers search for promising cancer drugs. Today, AI is helping speed up drug discovery.

  10. Anthropology

    50 years ago, evidence showed that an extinct human ancestor walked upright

    Fossil finds have since pushed back the ability of hominids to walk on two legs by millions of years.

  11. Health & Medicine

    A 25-year-effort uncovers clues to unexplained deaths in children

    When Laura Gould’s daughter died in 1997, there was almost no research in unexpected deaths in children older than one. Gould helped change that.

  12. Paleontology

    50 years ago, trilobite eyes mesmerized scientists

    Decades of research has confirmed that for such simple creatures, trilobites had astoundingly complex eyes.
