  1. Brain

    To protect kids, get the lead out!

    Lead poisons hundreds of thousands of children. In Chicago, experts show how the toxic metal hurts test performance in school.

  2. Math

    Explainer: Correlation, causation, coincidence and more

    Don’t jump to conclusions from statistics unless you understand correlation, causation, coincidence and confounding factors.

  3. Tech

    Inspired minds: Role models come from across the globe

    Innovators come from everywhere, as shown by the role models cited by students taking part in the 2015 Broadcom MASTERS International program.

  4. Computing

    These young scientists are passionate about tech and math

    The 2015 Broadcom MASTERS International delegates show why math and computer skills are key to the success of science-fair projects.

  5. Health & Medicine

    New ways to fight the flu

    Influenza sickens millions each year. A worldwide epidemic could kill many of them. Fortunately, new ways to fight the flu offer hope — before it’s too late.

  6. Agriculture

    Ditching farm pollution — literally

    An Indiana project shows how fighting fertilizer runoff can save farmers money, protect wild habitats and prevent harmful algae blooms.

  7. Genetics

    Silencing genes — to understand them

    Hijacking a cell process called RNA interference can let scientists turn off a selected gene. Its silencing can point to what genes do when they’re on — and may lead to new treatments for disease.

  8. Earth

    Explainer: Understanding plate tectonics

    Plate tectonics is the process whereby Earth continually rebuilds itself — and causes destructive events like earthquakes and volcanic eruptions.

  9. Computing

    3-D Recycling: Grind, melt, print!

    A new 2-in-1 desktop machine quickly recycles plastic trash into low-cost 3-D printer ‘ink’ at the push of a button.

  10. Tech

    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.

  11. 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.

  12. 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.
