  • Chasing neutrinos at the South Pole
    Chasing neutrinos at the South Pole

    Neutrinos are odd: Extremely difficult to see, they travel through mass with scarcely a trace. A 1-billion ton detector in South Pole ice is now counting neutrinos, intent on understanding their origin and role in the universe, and even spotting echoes of the Big Bang.

  • I robot. Aye science!
    I robot. Aye science!

    Military technology supports atmospheric and ocean science! 1: a robot sub smart enough to find stuff in the deep ocean 2: a metal fish glides for weeks under the ice 3: an electric sinker-bobber that never needs recharging 4: a research jet that flies miles above airliners.

  • Plumbing ancient Mayan plumbing!
    Plumbing ancient Mayan plumbing!

    A small constriction in a buried pipe shows that the Maya were using pressurized pipes before year 750. It’s more proof that when it comes to water, people get inventive! And what did the Maya do with the New World’s oldest plumbing? How about storing water, supplying drinking water, and flushing toilets?

  • Video surveillance: Who is watching you?
    Video surveillance: Who is watching you?

    London pioneered video surveillance in public, but it’s catching on fast. Many major cities have systems, and more are coming. What do these cameras learn? How do they interact with other sources of data? In this culture of disclosure should we even worry about privacy?

  • Fertilizing the ocean
    Fertilizing the ocean

    As Earth warms, should we try huge geoengineering projects to cool the climate? Would adding iron to fertilize ocean plants withdraw enough carbon dioxide to slow warming — or backfire?

  • Happy Thanksgiving! We celebrate eating — and food.

    Happy Thanksgiving! We celebrate eating — and food. Hungry: Is that your “food clock” ringing? Why does a fruitfly need to smell? How does bitter taste to you? And could eating MSG make you fat?

  • Hungry? History has lessons for improving farm productivity.

    After World War II, the “green revolution” sparked an explosion in farm output in developing countries. With soaring food prices and spreading food riots, what can we learn from the green revolution?

  • Pilot perfection: Errors plunge!

    Pilot errors have dropped 40 percent over 20 years, but on-the-ground accidents have increased. Why have pilot errors declined? What work remains to increase airline safety?

    California burnin’: Are we building in harm’s way?

    Wildfires are a tragedy, but are human actions making them worse? What is the role of global warming and zoning? Can we build safer houses in safer locations?

  • Tree frog’s foot yields re-stickable glue!

    Most adhesives can’t be reused. But a radical new design, based on the foot of frogs, lizards and insects, shows how engineers can learn from nature to make smarter materials.
