DTU researchers film protein quake for the first time
One of nature's mysteries is how plants survive impact by the huge amounts of energy contained in the sun's rays, while using this energy for photosynthesis. The hypothesis is that the light-absorbing proteins in the plant's blades quickly dissipate the energy throughout the entire protein molecule through so-called protein quakes. Researchers at DTU Physics have now managed to successfully 'film' this process.

Scientists craft atomically seamless, thinnest-possible semiconductor junctions
The University of Washington researchers have demonstrated that two single-layer semiconductor materials can be connected in an atomically seamless fashion known as a heterojunction. This result could be the basis for next-generation flexible and transparent computing, better light-emitting diodes, or LEDs, and solar technologies.

Stanford scientists develop a water splitter that runs on an ordinary AAA battery
Although touted as zero-emissions vehicles, most fuel cell vehicle run on hydrogen made from natural gas. Now Stanford scientists have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis. Unlike other water splitters that use precious-metal catalysts, the electrodes in the Stanford device are made of inexpensive and abundant nickel and iron.

Water window imaging opportunity
Ever heard of the water window? It consists of radiations in the 3.3 to 4.4 nanometer range, which are not absorbed by the water in biological tissues. A new theoretical study identifies the physical mechanism needed to efficiently generate harmonic radiations at high laser intensities that occur beyond the saturation threshold of atoms and molecules. These findings, aimed at improving conventional methods of coherent radiation production to reach the water window, were published in EPJ D.

Scientists observe quantum vortices in cold helium droplets
An international research team including DESY scientists has observed tiny quantum vortices in cold droplets of liquid helium. It is the first time that the quantum vortices, which have been observed in larger samples of superfluid helium before, have been detected in nanodroplets, as the team reports in the journal Science. 'The experiment has exceeded our best expectations,' says Andrey Vilesov of the University of Southern California, one of the experiment's three leads.

Artificial cells act like the real thing
Weizmann Institute scientists have created an artificial, network-like cell system that is capable of reproducing the dynamic behavior of protein synthesis. This achievement is not only likely to help gain a deeper understanding of basic biological processes, but it may, in the future, pave the way toward controlling the synthesis of both naturally-occurring and synthetic proteins for a host of uses.

Laser makes microscopes way cooler
Laser physicists have found a way to make atomic-force microscope probes 20 times more sensitive and capable of detecting forces as small as the weight of an individual virus. The technique, developed by researchers at the Australian National University, hinges on using laser beams to cool a nanowire probe to -265 degrees Celsius.

Scientists fold RNA origami from a single strand
RNA origami is a new method for organizing molecules on the nanoscale, making it possible to fabricate complicated shapes from a single strand of RNA. Unlike existing methods for folding DNA molecules, RNA origamis are produced by enzymes and simultaneously fold into pre-designed shapes. This may allow designer RNA structures to be grown within living cells and used to organize cellular enzymes into biochemical factories. The method is reported in the latest issue of Science.
