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.

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
