Razor-sharp optics on ground-based telescopes now allows astronomers to peer at events occurring near the very edge of our galaxys central black hole, providing new clues about the massive but invisible object at the core of the Milky Way.
The whirling accretion disk surrounding the supermassive black hole (center) at the core of the Milky Way Galaxy. As hot gas falls into the black hole, the energy is converted into radiation which is emitted in sudden bursts. The infrared emissions detected recently may accompany blobs of gas ejected from the disk (purple) or come from sparks that occur randomly in the accreting gas (yellow).

In a paper in this weeks issue of Nature, a team led by University of California, Berkeley, physicist Reinhard Genzel, who also directs the Max-Planck Institute for Extraterrestrial Physics (MPE) in Garching, Germany, reports the detection of powerful infrared flares from a region just outside the supermassive black hole.
If the black hole, which has a mass about 3.6 million times that of the sun, were at the center of our solar system, the flares would have come from somewhere within the orbit of Earth.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
