While some firms have developed for the Segway, he has filed a on a movable seat that doubles up as a controller, allowing the rider to steer and shift the Segway鈥檚 centre of gravity 鈥� all with a twist of the derriere.
Israeli researchers have made a that causes water droplets placed on it to form near-perfect spheres that minimise contact with the surface (Nanoletters, ). The material, which also immobilises the droplets, could be used to capture protein molecules inside water droplets, so they can be observed unfolding unhindered by contact with the surface.
