    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.

  2. Physics

    Nobel goes for making white LEDs possible

    The 2014 Nobel Prize in Physics has been awarded to scientists who discovered how to make blue light-emitting diodes. People really wanted white LEDs. The missing ingredient in making them was a building block: the blue LED.

    Repelling germs with ‘sharkskin’

    A biotechnology company has found a way to repel superbugs without toxic chemicals. It mimics the texture of a shark’s skin.

    Invisible plastic ‘ink’ foils counterfeiters

    Hidden images make a new label virtually counterfeit-proof, thanks to a combination of chemistry and nanotechnology.

    Cool Jobs: Data detectives

    Statisticians are experts in seeing the patterns hidden within the raw numbers called data. They especially excel at finding real trends, while eliminating what is actually due to chance. That’s why they offer a good reality check in any field that involves numbers.

    Looking unbelievably cool

    Everything above absolute zero gives off some heat. Usually objects radiate more heat — or energy — as their temperature climbs. But engineers now have created a material that sometimes appears to cool even as it is warming.

  7. Chemistry

    Cool Jobs: Repellent chemistry

    Chemistry is just one way to repel water in nature. Structure, or the shape of things, is another. To excel at water repellency, the lotus leaf relies on both.
