![]() | Robots could get 'touchy' with self-powered smart skin
Smart synthetic skins have the potential to allow robots to touch and sense what's around them, but keeping them powered up and highly sensitive at low cost has been a challenge. Now scientists report in the journal ACS Nano a self-powered, transparent smart skin that is simpler and less costly than many other versions that have been developed.

![]() | Physicists quantify the usefulness of 'quantum weirdness'
(Phys.org)—For the past 100 years, physicists have been studying the weird features of quantum physics, and now they're trying to put these features to good use. One prominent example is that quantum superposition (also known as quantum coherence)—which is the property that allows an object to be in two states at the same time—has been identified as a useful resource for quantum communication technologies.

![]() | Elusive state of superconducting matter discovered after 50 years
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory, Cornell University, and collaborators have produced the first direct evidence of a state of electronic matter first predicted by theorists in 1964. The discovery, described in a paper published online April 13, 2016, in Nature, may provide key insights into the workings of high-temperature superconductors.

![]() | Electrons slide through the hourglass on surface of bizarre material
A team of researchers at Princeton University has predicted the existence of a new state of matter in which current flows only through a set of surface channels that resemble an hourglass. These channels are created through the action of a newly theorized particle, dubbed the "hourglass fermion," which arises due to a special property of the material. The tuning of this property can sequentially create and destroy the hourglass fermions, suggesting a range of potential applications such as efficient transistor switching.

![]() | Are humans the new supercomputer? Team blurred the boundaries between man and mac
The saying of philosopher René Descartes of what makes humans unique is beginning to sound hollow. 'I think—therefore soon I am obsolete' seems more appropriate. When a computer routinely beats us at chess and we can barely navigate without the help of a GPS, have we outlived our place in the world? Not quite. Welcome to the front line of research in cognitive skills, quantum computers and gaming.

![]() | Riddle of missing efficiency in zinc oxide-based dye-sensitised solar cells solved
To convert solar energy into electricity or solar fuels, you need specialised systems of materials such as those consisting of organic and inorganic thin films. Processes at the junction of these films play a decisive role in converting the solar energy. Now a team at HZB headed by Prof. Emad Aziz has used ultra-short laser pulses and observed for the first time directly how boundary states form between the organic dye molecules and a zinc-oxide semiconductor layer, temporarily trapping the charge carriers. This explains why zinc-oxide (ZnO) dye-sensitised solar cells have not yet met expectations. The results evolved from collaboration between Monash University (Australia) and Joint Lab partners Helmholtz Zentrum Berlin (HZB) and the Freie Universität Berlin (FU Berlin). They have now been published online by Nature in the open access magazine Scientific Reports.

![]() | New imaging technique reveals vulnerability of coral reefs
Corals, the primary reef builders on coral reefs, are often the star player in research studies addressing the impacts of climate change on coral reefs because they are the foundation of coral reef ecosystems. However, the breakdown of coral reefs from borers (such as bivalves, sponges, and marine worms) and grazers (such as parrotfish and urchins)—called bioerosion—and growth from encrusting algae and invertebrates (for example, oysters and barnacles) - called secondary accretion—are critical processes for reef sustainability.
