  • When dead men speak…
    When dead men speak…

    British archeologists unearthed bones of Richard III, who died in 1485 after a murderous reign. How do bones, isotopes, historic records, DNA and grave goods tell us about the dead?

  • Wave power
    Wave power

    The first ocean wave energy-capturing device with a permit to connect back to a public power grid will enter the Pacific next month. How much power could the U.S. potentially harness from the waves crashing into its the coastline? According to researchers, wave energy might be one of our best renewable resources.

  • Boasting about the boson
    Boasting about the boson

    “Yes, but…” is the word from the frontiers of physics. The world’s largest atom smasher has blasted protons against each other with such enormous energy that they have — apparently — appeared in the debris of decaying particles. At last, matter can have mass!

  • Rennaissance man wonders: Denial of science, science of denial ... Why do so many doubt evolution, warming?
    Denial of science, science of denial Tobacco and cancer. CFCs and ozone. Vaccines and autism. And evolution through natural selection, acid rain and global warming. Why do the facts get lost in a cacophony of argument, falsehood and outright denial? A conference looks at why the media get taken for a ride, and how they can improve.

  • Flying robots
    Flying robots

    Compared to regular airplanes, radio-controlled craft are safer, cheaper, and easier to use for observing wildlife and environmental conditions. Where are these robots being used? What are they finding? And as prices continue to fall, what stands in the way of much broader use?

  • Biology as engineer
    Biology as engineer

    Long ago, nature devised the hinge and ball and socket for appendages like legs and wings. The screw is the latest simple machine to be discovered in nature. Why do weevils, a type of beetle, have a screw? How does it help weevils survive their 3-D world?

  • Nuclear nightmare in Japan
    Nuclear nightmare in Japan

    With three nuclear reactors and three pools of spent fuel teetering on the edge of meltdown, Japanese technicians struggled to throttle the nuclear demons after the gigantic tsunami. Is Fukushima closer to Chernobyl or Three Mile Island? How will the disaster affect plans for a renaissance of nuclear power?

  • 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.

  • Old-new glue for plywood, composites
    Old-new glue for plywood, composites

    Plywood used to be bonded with soybean glue; then along came synthetic adhesives. They were strong and cheap, but they did release toxic formaldehyde. Now, industry is switching to a new, improved soy adhesive. Tough, water-resistant soy glue does not release formaldehyde, and is already being used for interior plywood.

  • Brick building side showing 12 stories of windows, each with an air conditioner
    Future grid, smart grid

    We need more electricity. More alternative energy. Less greenhouse warming, and better ways to manage our power supply. Can the electric grid meet multiple challenges and help us survive prosperity? What good are smart meters? And what is this going to cost?
