A key obstacle to controlling on Earth the fusion that powers the sun and stars is leakage of energy and particles from plasma, the hot, charged state of matter composed of free electrons and atomic nuclei that fuels fusion reactions. At the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL), physicists have been focusing on validating computer simulations that forecast energy losses caused by turbulent transport during fusion experiments.

Astronomers, for the first time, have snapped an image of a cool, gassy ring swirling around the supermassive black hole at the center of our galaxy.This ring is part of the so-called accretion disk -- stars, dust and gases -- that surround most black holes. These materials are held close by the black hole's strong gravitational grip and the far edge represents the outer limits of its gravitational reach. In the case of the Milky Way's black hole called Sagittarius A*, the disk extends out a few tenths of a light-year from the black hole's event horizon -- the point at which even light can't escape the black hole's grasp.

In conventional electron microscopes, performing atomic-resolution observations of magnetic materials is particularly difficult because high magnetic fields are inevitably exerted on samples inside the magnetic objective lens.

This enables direct, atom-resolved imaging of magnetic materials such as silicon steels. This novel electron microscope is expected to be extensively used for the research and development of advanced magnetic materials.

00:39 Yahoo ScienceStephen Hawking Was Right: Black Holes Can Evaporate, Weird New Study Shows

In 1974, Stephen Hawking made one of his most famous predictions: that black holes eventually evaporate entirely.According to Hawking's theory, black holes are not perfectly "black" but instead actually emit particles. This radiation, Hawking believed, could eventually siphon enough energy and mass away from black holes to make them disappear. The theory is widely assumed to be true but was once thought nearly impossible to prove.For the first time, however, physicists have shown this elusive Hawking radiation -- at least in a lab. Though Hawking radiation is too faint to be detected in space by our current instruments, physicists have now seen this radiation in a black hole analog created using sound waves and some of the coldest, strangest matter in the universe.

23:55 Photonics.comGrowing 2D Crystals Over 3D Surfaces Could Be a Way to Engineer Quantum Emission

A team led by the Oak Ridge National Laboratory (ORNL) explored how 2D crystals grow over 3D objects and how the curvature of 3D objects can stretch and strain the 2D crystals. The team’s findings could lead to a strategy for engineering strain during the growth of crystals to fabricate single-photon emitters for quantum information processing. When atomically thin 2D crystals were grown on substrates patterned with sharp steps and trenches, the crystals grew up and down these flat obstacles without changing their properties or growth rates. However, when the 2D crystals were grown on curvy surfaces, the crystals were forced to stretch as they grew in order to maintain their crystal structure. The researchers found that they could govern the amount of strain that was passed on to a crystal by controlling the topographic curvature of the substrate. Using strain engineering, the

The conclusion is that only the constraints on the parameters of modified gravity benefit significantly from including the DES year 1 data, making these consistent with predictions from general relativity.

I want to know His thoughts; the rest are just details."The phrase "God's thoughts" is a delightfully apt metaphor for the ultimate goal of modern physics, which is to develop a perfect understanding of the laws of nature -- what physicists call "a theory of everything," or TOE.

17:04 Phys.orgSpecific ion effects directed noble metal aerogels

Noble metal foams (NMFs) are a new class of functional materials that contain both noble metals and monolithic porous materials for impressive multi prospects in materials science and multidisciplinary fields. In a recent study now published on Science Advances, Ran Du and a team of interdisciplinary researchers in Physical Chemistry, Materials Engineering and Physics developed highly tunable NMFs by activating specific ion effects to produce a variety of single/alloy aerogels. The new materials contained adjustable composition—with gold (Au), silver (Ag), palladium (Pd) and platinum (Pt)—and special morphologies.

16:51 Phys.orgElectron bunches keep ions cool at RHIC

Accelerator physicists have demonstrated a groundbreaking technique using bunches of electrons to keep beams of particles cool at the Relativistic Heavy Ion Collider (RHIC)—a U.S. Department of Energy Office of Science user facility for nuclear physics research at Brookhaven National Laboratory. This "bunched-beam" electron cooling technique will enable higher particle collision rates at RHIC, where scientists study the collision debris to learn about the building blocks of matter as they existed just after the Big Bang.

16:39 Phys.orgQuantum supremacy and its efficient certification difficult to achieve simultaneously

In an ironic twist, physicists have shown that the very property that can be used to show that quantum computing devices can solve some problems that classical computers cannot also makes it impossible to efficiently certify that this "quantum supremacy" has indeed been achieved, for a wide variety of schemes. In quantum computing, the issue of certification is crucial for formally verifying the superior computing power of quantum devices.

14:48 Phys.orgThe physical limit of quantum optics resolves a mystery of computational complexity

Linear optics comprises one of the best examples for demonstrating quantum physics. It works at room temperatures, and can be observed with relatively simple devices. Linear optics involves physical processes that conserve the total number of photons. In the ideal case, if there are 100 photons at the beginning, no matter how complicated the physical process is, there will be exactly 100 photons left in the end.
