Computer-assisted technology developed especially for this purpose combines the advantages of both methods and suppresses unwanted noise. This makes highly precise filming of dynamic processes at the nanometer scale possible eg photosynthesis or high-temperature superconductivity.

The new camera from Dresden enables unaltered optical measurements of extremely small, dynamic changes in biological, chemical or physical processes...

New Design could finally help to bring Fusion Power closer to reality

Advances in magnet technology have enabled researchers at MIT to propose a new design for a practical compact tokamak fusion reactor—and it’s one that might be realized in as little as a decade, they say. Using rare-earth barium copper oxide (REBCO) superconducting tapes, to produce high-magnetic field coils “just ripples through the whole design,” says Prof Dennis Whyte.

The stronger magnetic field makes it possible to produce the required magnetic confinement of the superhot plasma—that is, the working material of a fusion reaction—but in a much smaller device than those ...

Large-area Integration of Quantum dots, Photonic crystals produce brighter, more Efficient Light

To demonstrate their new technology, researchers fabricated a novel 1mm device (aka Robot Man) made of yellow photonic-crystal-enhanced QDs. Every region of the device has thousands of quantum dots, each measuring about six nanometers. Credit: Gloria See, University of Illinois at Urbana-Champaign

A new method to extract more efficient and polarized light from quantum dots (QDs) over a large-scale area has been developed by researchers. Their method, which combines QD and photonic crystal technology, could lead to brighter and more efficient mobile phone, tablet, and computer displays, as well as enhanced LED lighting.

The team embedded QDs in novel polymer materials that retain strong quantum efficiency...

Artificially Evolved Robots Efficiently Self-Organize Tasks

Task partitioning in insects and robots

Task partitioning in insects and robots. (a) Task partitioned retrieval of leaf fragments, as found in most Atta leafcutter ants that harvest leaves from trees. Dropper ants cut leaves which then accumulate in a cache, after which the leaves are retrieved by collectors and brought back to the nest, where they serve as a substrate for a fungus which is farmed as food. Ants also occasionally use a generalist strategy whereby both tasks are performed by the same individuals. (b) Analogous robotics setup, whereby items have to be transported across a slope using the coordinated action of droppers, collectors and possibly generalists...
