Dusty Surprise Around Giant Black Hole
ESO’s Very Large Telescope Interferometer has gathered the most detailed observations ever of the dust around the huge black hole at the centre of an active galaxy. Rather than finding all of the glowing dust in a doughnut-shaped torus around the black hole, as expected, the astronomers find that much of it is located above and below the torus. These observations show that dust is being pushed away from the black hole as a cool wind — a surprising finding that challenges current theories and tells us how supermassive black holes evolve and interact with their surroundings.

Beyond Silicon: Transistors without Semiconductors
Electrons flash across a series of gold quantum dots on boron nitride nanotubes. Michigan Tech scientists made the quantum-tunneling device, which acts like a transistor at room temperature, without using semiconducting materials.

Billion-Pixel View of Mars Comes From Curiosity Rover
This is a reduced version of panorama from NASA's Mars rover Curiosity with 1.3 billion pixels in the full-resolution version. It shows Curiosity at the "Rocknest" site where the rover scooped up samples of windblown dust and sand. Curiosity used three cameras to take the component images on several different days between Oct. 5 and Nov. 16, 2012.
