  1. Health & Medicine

    50 years ago, scientists hoped freezing donor organs would boost transplants

    In the 1970s, biologists hoped to freeze organs so more could last long enough to be transplanted. Scientists are now starting to manage this feat.

  2. Space

    Six months in space leads to a decade’s worth of long-term bone loss

    Even after a year of recovery in Earth’s gravity, astronauts who’d been in space six months or more still had bone loss equal to a decade of aging.

  3. Tech

    A neck patch for athletes could help detect concussions early

    The small sensor is sleeker and cheaper than other devices used to monitor neck strain in athletes.

  4. Quantum Physics

    Aliens could send quantum messages to Earth, calculations suggest

    Scientists are developing quantum communications networks on Earth. Aliens, if they exist, could be going further.

  5. Environment

    Flower shape and size impact bees’ chances of catching gut parasites

    Bumblebees have higher chances of contracting a gut parasite from short, wide flowers than from blooms with other shapes, experiments show.

  6. Astronomy

    Clouds in the Milky Way’s plasma bubbles came from the starry disk — and far beyond

    Gas clouds in the Fermi bubbles have a wide range of chemical compositions, suggesting some may have been ripped from other galaxies.

  7. Dogs are great sniffers. A newfound nose-to-brain connection helps explain why

    A new anatomical description of how smell works in a dog brain shows why they’re such good sniffers.

  8. Planetary Science

    A new look at the ‘mineral kingdom’ may transform how we search for life

    A new census of Earth’s crystal past hints that life may have begun earlier than expected, and could be a tool to look for water and life elsewhere.

  9. Particle Physics

    A supersensitive dark matter search found no signs of the substance — yet

    The LZ experiment’s first measurement raises hopes that scientists are closer than ever to finding the source of much of the universe’s mass.

  10. Environment

    How to build better ice towers for drinking water and irrigation

    “Ice stupas” emerged in 2014 as a way to cope with climate change shrinking glaciers. Automation could help improve the cones’ construction.

  11. Paleontology

    Feathers may have helped dinosaurs survive the Triassic mass extinction

    New data show that dinosaurs were able to weather freezing conditions about 202 million years ago, probably thanks to warm feathery coats.
