    Digging a trench to stop a tsunami

    Boyd Kane built his own wave tank to study tsunamis and how he might change the seafloor to stop their advance.

  2. Slime: A new way to protect plants from slugs

    Katie Gwaltney had a slug problem in her garden. She decided to try using the slugs’ own slime against them. Her findings earned the high school freshman a finalist’s spot at this week's Intel International Science and Engineering Fair.

  3. Tech

    The road less worn

    Two teens have found a new use for old tires. By grinding them up and adding them to asphalt, the old rubber can create stronger, longer-lived roads. And the bonus: The process recycles tires that might otherwise have been burned, creating pollution.

  4. Tech

    Fighting theater pirates

    How can theaters thwart thieves from unlawfully recording a movie during a showing? A high-school freshman’s low-cost solution relies on simple physics.

  5. Tech

    Making magic with mechanical engineering

    As kids, we all want to make magic. But Michelle Phillips took that dream further. She realized that she wanted to build rides for amusement parks.

  6. Computing

    Electricity: Cutting the cords

    Engineers are working to charge more wireless gadgets — without relying on cords and plugs.

  7. Science & Society

    Students use STEM to help their community

    Every community has its problems. A nationwide contest encourages students to tap science to solve local needs.

  8. Chemistry

    Urine may make Mars travel possible

    On Earth, urine is a waste. En route to Mars, it could be a precious renewable commodity: the source of drinking water and energy.

  9. Physics

    World’s coolest ‘clock’ is also crazy-accurate

    This is the time to beat — the world’s most accurate atomic clock ever. At its heart is a ‘fountain’ of cesium atoms chilled nearly to absolute zero!

  10. Teaching clean energy with the power of wind

    A build-your-own wind energy machine can be a fun and inexpensive way to practice engineering and discover the power of wind.

  11. Physics

    Sending student science to space

    Two teachers describe how they worked with the Student Spaceflight Experiments Program to get middle-school scientists excited about research and space.

  12. Physics

    Filter lets in only the right light

    Scientists have built a light filter that only permits light coming from one desired angle to pass through. Built from alternating layers of transparent materials, it could help minimize the glare in telescopes and cameras or boost the efficiency of solar cells.
