    Sunglasses on demand

    Plastics that conduct electricity let new color-changing sunglasses go from dark to light and back again at the tap of a switch. The shades could come in a range of colors too.

  2. Computing

    This ‘smart’ self-cleaning keyboard is powered by you

    A new electric keyboard locks out anybody but its owner. It’s not only self-cleaning but also powered by your fingertips.

  3. Brain

    Blowing up the brain

    When added to brain tissue, a chemical like one found in baby diapers expands. And it expands that brain tissue too, giving scientists a better view of how its cells connect.

  4. Animals

    Hellbenders need help!

    Hellbenders already face threats such as habitat loss, pollution and disease. But climate change could make matters worse. And the problems facing hellbenders could spell trouble for more than just these giant amphibians.

  5. Tech

    Rewritable paper: Prints with light, not ink

    Rewritable paper could save money, preserve forests and cut down on waste — and all without using any ink.

  6. Agriculture

    Livestock: A need to save rare breeds

    New studies and ongoing work highlight why society should save rare livestock breeds — and the part that technology can play.

  7. Agriculture

    Explainer: What is a gene bank?

    Most banks store money. But some very special ones store deposits that may prove even more valuable: tissues that could prevent the extinction of breeds and species.

  8. Computing

    Explainer: What is a computer model?

    Computer models use data, math and computer instructions to predict events in the real world.

  9. Brain

    Scents may affect how appealing tobacco is

    Menthol’s effects on the brain may make tobacco more addicting. In contrast, foul odors might help smokers quit. Two new studies show how.

  10. Computing

    Models: How computers make predictions

    They use numbers to model real-world activities. And new insights in math are streamlining models’ design.

  11. Microbes

    Recycling the dead

    When things die, nature breaks them down through a process we know as rot. Without it, none of us would be here. Now, scientists are trying to better understand it so that they can use rot — preserving its role in feeding all living things.

  12. Health & Medicine

    Watch out: Cell phones can be addictive

    Smartphones and Facebook are convenient. New research shows that for some people they also can become dangerously addictive.
