    How science saved the Eiffel Tower

    The Eiffel Tower was an engineering masterpiece. But Parisians initially thought it too ugly to let stand for more than 20 years. So Eiffel made the tower a bastion of science. And that would soon ensure that the structure was too valuable to tear down.

    Nobel goes for creating the ‘nanoscope’

    A regular microscope can’t bring into focus the nanoscale molecules from which cells are built. Using lasers and fluorescent molecules, three scientists found a way to view these tiny features. Their reward: the 2014 Nobel Prize in chemistry.

    Squishy robot propelled by ka-pow!

    This is not your average robot. It flies through the air, propelled by an explosion in one of its arms. It could prove useful in disaster areas or war zones.

    3-D printers are making cars!

    3-D printing technology makes it possible to print anything — even a car. A team of engineers designed the Strati and then printed the electric cars at events in Chicago and New York.

    Explainer: What is 3-D printing?

    A new type of computer printer is already doing a lot more than spraying ink onto paper. Some dispense metal, plastic, food — even cells. In short order, people may be able to manufacture almost anything from their home or office.

    Pyramids’ blocks: Possibly rock ‘n’ rolled

    No one knows how the ancient Egyptians moved the big stones needed to build their pyramids. A new study suggests they could have rolled them, by attaching wooden posts to the sides.

    Soaking up oil spills — with cotton

    Natural, low-grade cotton could help clean up oil spills better than synthetic materials, a new study finds. And unlike synthetics, cotton breaks down naturally.

    Plants ‘listen’ for danger

    Scientists used lasers to show that plants can “hear” insect pests. Those leafy plants then mount a chemical attack in response to the bug’s chewing sounds — but not toward harmless noises such as a gentle breeze or a bug’s mating call.
