Light-matter interaction without interference  

Quantum dots might constitute the foundation of quantum communication. They are an efficient interface between matter and light, with photons emitted by the quantum dots transporting information across large distances. However, structures form by default during the manufacture of quantum dots that interfere with communication. Researchers have now successfully eliminated these interferences.

Switching electron properties on and off individually  

Electrons have different properties - and they all can be used to create order in solid objects. This order determines the properties of the material. Experiments now show: It is possible to influence different characteristics of the electrons separately from each other. Closely interwoven quantum phenomena can thus be understood individually.

Storms on Jupiter are disturbing the planet's colorful belts  

Coordinated observations of Jupiter in early 2017 by six ground-based telescopes and Hubble allowed astronomers to study the evolution of bright plumes and connect them with cloud movements deep in the planet. They show that these plumes originate 80 kilometers below the surface cloud deck and rise up quickly into the stratosphere, where supercooled ammonia freezes to form ammonia ice clouds. The plumes create disturbances in the belts and even change their color.

First microscopic look at a tiny phenomenon with big potential implications  

Matter behaves differently when it's tiny. At the nanoscale, electric current cuts through mountains of particles, spinning them into vortexes that can be used intentionally in quantum computing. The particles arrange themselves into a topological map, but the lines blur as electrons merge into indistinguishable quasiparticles with shifting properties. The trick is learning how to control such changeable materials.

Scorpion toxin that targets 'wasabi receptor' may help solve mystery of chronic pain  

Researchers have discovered a scorpion toxin that targets the 'wasabi receptor,' a chemical-sensing protein found in nerve cells that's responsible for the sinus-jolting sting of wasabi. Because the toxin triggers a pain response, scientists think it can be used as a tool for studying chronic pain and inflammation, and may eventually lead to the development of new kinds of non-opioid pain relievers.
