  1. Space

    Scientists Say: Accretion Disk

    Cosmic swirls of gas, dust and plasma, accretion disks reveal the shadowy silhouettes of black holes and more.

  2. Environment

    Sea life may suffer as plastic bits alter metals in water

    This interplay between plastics and metals could affect how each affects the environment — and suggests opportunities for controlling their risks.

  3. Environment

    Microplastic pollution aids viruses and prolongs their infectivity

    The tiny plastic bits give these germs safe havens. That protection seems to increase as the plastic ages and breaks into ever smaller pieces.

  4. Chemistry

    Explainer: What is a hydrogel?

    These unusual materials have a host of unusual properties. You can even make a starch-infused version in your kitchen.

  5. Animals

    Sea creatures’ fishy scent protects them from deep-sea high pressures  

    TMAO’s water-wrangling ability protects a critter’s critical proteins — including muscle — from crushing under deep ocean pressures.

  6. Tech

    No trees were harmed to 3-D print this piece of wood

    How clever! Scientists used print-speed adjustments to control how flat, 3-D printed shapes morph into complex wooden objects.

  7. Plants

    No sun? No prob! A new process might soon grow plants in the dark

    Teamwork makes green-work! Collaborating scientists came up with an electrifying farming trick that could make sunlight optional.

  8. Health & Medicine

    Patches and robotic pills may one day replace injections

    Instead of a shot in the arm, a light-activated patch or robotic pill may one day deliver your medicine.

  9. Health & Medicine

    Like bloodhounds, worms are sniffing out human cancers

    Scents emitted by diseased cells may usher in a new era of safe, low-cost screening tests for cancer and other illnesses.

  10. Materials Science

    New cloth cools you when you’re hot, warms you when you’re cold

    Scientists 3-D printed the new fabric, which has even more tricks up its sleeve — such as conducting electricity and resisting radio waves.

  11. Environment

    Widely used pesticides may threaten Earth’s ozone layer

    Data show a major class of long-used “eco-friendly” copper chemicals unexpectedly react with soil, making gases harmful to Earth’s protective ozone layer.

  12. Environment

    Clothes dryers may be a major source of airborne microplastics

    Scientists thought washing machines were a leading contributor of microplastics. Now it appears dryers may be an even bigger problem.
