An overview of regulatory solutions worldwide on the use of nanotechnology in food and feed production shows a differing approach: only the EU and Switzerland have nano-specific provisions incorporated in existing legislation, whereas other countries count on non-legally binding guidance and standards for industry.
The discovery experimentally connects the worlds of classical and quantum mechanics and illuminates the mysterious nature of the Mott transition. It also could shed light on non-equilibrium physics, which is poorly understood but governs most of what occurs in our world. The finding may also represent a step towards more efficient electronics based on the Mott transition.
Future computers will require a magnetic material which can be manipulated ultra-rapidly by breaking the strong magnetic coupling. In a new study, Swedish and German scientists demonstrate that even the strongest magnetic coupling may be broken within picoseconds. This will open up an exciting new area of research.
Researchers have fabricated molecular motors on a metal substrate using supramolecules, and successfully reversed rotation of molecular motors by rearranging bonding between molecules that constitute a supramolecule.
It's not lightsaber time, not yet. But a team of theoretical physicists has taken another step toward building objects out of photons, and the findings hint that weightless particles of light can be joined into a sort of 'molecule' with its own peculiar force.
