The day of charging cellphones with finger swipes and powering Bluetooth headsets simply by walking is now much closer. Michigan State University engineering researchers have created a new way to harvest energy from human motion, using a film-like device that...
Helium atoms are loners. Only if they are cooled down to an extremely low temperature do they form a very weakly bound molecule. In so doing, they can keep a tremendous distance from each other thanks to the quantum-mechanical...
Mapping the interaction of a single atom with a single photon may inform design of quantum devices. Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the...
Just like workers in a factory, enzymes can create a final product more efficiently if they are stuck together in one place and pass the raw material from enzyme to enzyme, assembly line-style. That's according to scientists at Cornell's...
A team of physicists at The Australian National University (ANU) has used a technique known as 'ghost imaging' to create an image of an object from atoms that never interact with it. This is the first time that ghost imaging...
A Waseda University (Tokyo) research group has developed a polymer which can store hydrogen in a light, compact and flexible sheet, and is safe to touch even when filled with hydrogen gas. Although research and development on technology allowing hydrogen...
Tiny, glowing crystals designed to detect and capture heavy-metal toxins such as lead and mercury could prove to be a powerful new tool in locating and cleaning up contaminated water sources. Motivated by publicized cases in which high levels of...
Technion researchers have demonstrated, for the first time, that laser emissions can be created through the interaction of light and water waves. This "water-wave laser" could someday be used in tiny sensors that combine light waves, sound and water...
Graphene is currently one of the most extensively studied materials in the world, both on a scientific and industrial level. The world's first two-dimensional material, this single layer of carbon atoms arranged in a hexagonal lattice has a series...
A nanosize squeeze can significantly boost the performance of platinum catalysts that help generate energy in fuel cells, according to a new study by Stanford scientists. The team bonded a platinum catalyst to a thin material that expands and contracts...
