  1. Health & Medicine

    A new type of immune cell may cause lifelong allergies

    These special memory cells were present in people with allergies and absent in those without.

  2. Microbes

    What the weird world of protists can teach us about life on Earth

    Microbes vastly outnumber multicellular life on Earth. A close-up look at protists highlights how much we don't know about the microscopic world.

  3. Artificial Intelligence

    AI learned how to influence humans by watching a video game

    New research used the game Overcooked to show how AI can learn to collaborate with — or manipulate — us.

  4. Animals

    Let’s learn about animals’ bizarre sleep schedules

    From reindeer that snooze while chewing to penguins that take thousands of naps each day, the animal kingdom has some truly weird sleep patterns.

  5. Space

    Scientists Say: Corona

    The sun’s corona can only be seen without special instruments during a total solar eclipse.

  6. Space

    Explainer: What is the solar cycle?

    Here’s what causes the sun’s 11-year cycle of activity and what it means for us on Earth.

  7. Plants

    On hot summer days, this thistle stays cool to the touch

    Its yellow flowers can cool themselves substantially, staying up to 10 degrees C (18 degrees F) cooler in extreme heat.

  8. Earth

    Experiment: Can plants stop soil erosion?

    Soil erosion washes pollutants into streams and rivers — but plants may help limit that.

  9. Psychology

    You’re too distracted. Here’s why that matters and what to do about it

    Science reveals the many reasons we are so distracted, from poor sleep and social media to diet and exercise. It also shows us how to take back our focus.

  10. Animals

    Tardigrades survive harsh conditions by almost dying. Here’s how

    Under stress, a chemical change signals these water bears to switch between live and mostly dead.

  11. Physics

    Forests could help detect ‘ghost particles’ from space

    If trees could act as natural antennas, one physicist proposes that they just might pick up signals of hard-to-spot ultra-high energy neutrinos.

  12. Tech

    Scientists Say: Bionic

    This type of technology combines natural and synthetic systems. It can restore lost vision and mobility and even grant cells new abilities.
