Light-matter interaction without interference  SCIENCE DAILY · 2 days
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... more
In a quantum future, which starship destroys the other?  SCIENCE DAILY · 2 days
Quantum mechanics boasts all sorts of strange features, one being quantum superposition -- the peculiar circumstance in which particles seem to be in two or more places or states at... more
The case for retreat in the battle against climate change  SCIENCE DAILY · 2 days
With sea level rise and extreme weather threatening coastal communities, it's no longer a question of whether they are going to retreat; it's where, when and how. In... more
Cracking a decades-old test, researchers bolster case for quantum mechanics  SCIENCE DAILY · 2 days
Researchers have developed creative tactics to get rid of loopholes that have long confounded tests of quantum mechanics. With their innovative method, the researchers were able to demonstrate... more
Pollution and winter linked with rise in heart attack treatment  SCIENCE DAILY · 2 days
Heavily polluted areas have a higher rate of angioplasty procedures to treat blocked arteries than areas with clean air, according to new research. Procedures are even more common... more

Storms on Jupiter are disturbing the planet's colorful belts  SCIENCE DAILY · 3 days
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... more
Switching electron properties on and off individually  SCIENCE DAILY · 3 days
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... more
Researchers get first microscopic look at a tiny phenomenon with big potential implications  PHYS.ORG · 3 days
Matter behaves differently when it's tiny. At the nanoscale, electric current cuts through mountains of particles, spinning them into vortexes that can... more
Quantum gravity's tangled time  SCIENCE DAILY · 3 days
The theories of quantum mechanics and gravity are notorious for being incompatible, despite the efforts of scores of physicists over the past fifty years. However, physicists have now combined the key elements of the two theories describing the flow of... more
