A mysterious object is being dragged into the supermassive black hole at the Milky Way's center      (via sciencedaily.com) 

An object near the supermassive black hole at the center of the Milky Way galaxy has drawn the interest of scientists because it has evolved dramatically in a relatively short time. A new study suggests that the object, called X7, could be a cloud of dust and gas that was created when two stars collided. The researchers believe it will eventually be drawn toward the black hole and will disintegrate.

Heterostructures support predictions of counterpropagating charged edge modes at the v=2/3 fractional quantum Hall state      (via sciencedaily.com)     Original source 

Researchers have tested models of edge conduction with a device built on top of the semiconductor heterostructure which consists of gold gates that come close together. Voltage is applied on the gates to direct the edge states through the middle of the point contact, where they are close enough that quantum tunneling can occur between the edge states on opposite sides the sample. Changes in the electrical current flowing through the device are used to test the theorists' predictions.

How one of Saturn's moons ejects particles from oceans beneath its surface      (via sciencedaily.com) 

Enceladus, the sixth largest of Saturn's moons, is known for spraying out tiny icy silica particles -- so many of them that the particles are a key component of the second outermost ring around Saturn. Scientists have not known how that happens or how long the process takes. A study now shows that tidal heating in Enceladus' core creates currents that transport the silica, which is likely released by deep-sea hydrothermal vents, over the course of just a few months.

First transient electronic bandage speeds healing by 30%      (via sciencedaily.com) 

Researchers have developed a small, flexible, stretchable bandage that accelerates healing by delivering electrotherapy directly to the wound site. The bandage also actively monitors the healing process and then harmlessly dissolves -- electrodes and all -- into the body after it is no longer needed.

Meteorite crater discovered in French winery      (via sciencedaily.com) 

Countless meteorites have struck Earth in the past and shaped the history of our planet. It is assumed, for example, that meteorites brought with them a large part of its water. The extinction of the dinosaurs might also have been triggered by the impact of a very large meteorite. It turns out that the marketing 'gag' of the 'Domaine du Météore' winery is acutally a real impact crater. Meteorite craters which are still visible today are rare because most traces of the celestial bodies have long since disappeared again.
