In order to manage the huge task of transforming the current energy system to fit climate considerations, it is important to keep future ground-breaking technology options open while making early emission cuts by using energy more efficiently, says Franklin M. Orr, director of the Precourt Institute for Energy at Stanford University.
In studies of the motion of tiny swimming bacteria, scientists found that the microscopic organisms can stir fluids remarkably quickly and effectively. As a result, the bacterial flagella could act like tiny motors to mix chemicals in biomedical kits, among other applications.
Scientists are reporting development of a nano-size capsule that boosts the body's uptake of curcumin, an ingredient in yellow curry now being evaluated in clinical trials for treatment of several diseases.
Scientists have successfully wired a state-of-the-art artificial hand to existing nerve endings in the stump of a severed arm. The device, called SmartHand, resembles - in function, sensitivity and appearance - a real hand.
Engineering researchers at McMaster University have fabricated a palm-sized, automated, micro-injector that can insert proteins, DNA and other biomolecules into individual cells at volumes exponentially higher than current procedures, and at a fraction of the cost.
Electric vehicles are the future and researchers are working on developing such cars to fuel technology and protect the environment. Rising to meet this challenge head on is the E3CAR ('Energy efficient electrical car') project, funded in part by the EU and ENIAC (the European Nanoelectronics Initiative Advisory Council).
In a breakthrough development, researchers in Singapore have reported the invention of an essential component for single-molecule mechanical machines: a molecular gear that can be controllably rotated with a 100% rate of success.
