Insect-like flying robots can stick to surfaces
Tiny flying robots the size of insects can stick to walls and take off from ceilings, according to findings published in Science. The mini-drones conserve energy by perching, researchers say, and they stick to surfaces using electrostatic adhesion.
Small modular nuclear reactors take step closer to marketplace
Small modular nuclear reactors have moved a step closer to the marketplace with the Tennessee Valley Authority’s permit application to the Nuclear Regulatory Commission. Small modular reactors are more economical than large plants, can be built on a production line and are versatile due to their modularity. The application to build a small modular reactor facility signals a new era of nuclear power.
