A giant black hole destroys a massive star
A University of Michigan astronomer has made a thorough forensic study of a star that was torn apart when it ventured too close to a giant black hole and then had its insides tossed out into space. The research team used NASA's Chandra X-ray Observatory and ESA's XMM-Newton to study the amount of nitrogen and carbon near a black hole known to have torn apart a star.

Non-toxic cleaner developed for paintings
Organogels: New cleaning agent for artworks investigated with neutrons at the FRM II The restoration of artworks often involves solvents which have toxic properties. Now researchers have succeeded for the first time in creating a non-toxic and sustainable cleaning agent for paintings. Scientists at the Technical University of Munich (TUM) Research Neutron Source Heinz Maier-Leibnitz (FRM II) investigated the structure of the agent, referred to as an organogel.

Pairing of electrons in artificial atoms discovered
Researchers from the Department of Physics at Universität Hamburg, observed a quantum state that was theoretically predicted more than 50 years ago by Japanese theoreticians but so far eluded detection. By tailoring an artificial atom on the surface of a superconductor, the researchers succeeded in pairing the electrons of the so-called quantum dot, thereby inducing the smallest possible version of a superconductor.

Switching ’spin’ on and off (and up and down) in quantum materials at room temperature
Researchers have found a way to control the interaction of light and quantum -spin- in organic semiconductors, that works even at room temperature. These new materials hold great promise for completely new applications, since we've been able to remove the need for ultra-cold temperatures Sebastian Gorgon Spin is the term for the intrinsic angular momentum of electrons, which is referred to as up or down.

Magnonic computing: Faster spin waves could make novel computing systems possible
Breakthrough in research on novel energy-efficient computer Research is underway around the world to find alternatives to our current electronic computing technology, as great, electron-based systems have limitations. A new way of transmitting information is emerging from the field of magnonics: instead of electron exchange, the waves generated in magnetic media could be used for transmission, but magnonics-based computing has been (too) slow to date.

Scientists Theorize a Hidden Phase Transition Between Liquid and a Solid
Anything made out of plastic or glass is known as an amorphous material. Unlike many materials that freeze into crystalline solids, the atoms and molecules in amorphous materials never stack together to form crystals when cooled. In fact, although we commonly think of plastic and glass as "solids," they instead remain in a state that is more accurately described as a supercooled liquid that flows extremely slowly.

Simple superconducting device could dramatically cut energy use in computing, other applications
The ultrasmall "switch" could be easily scaled. MIT scientists and their colleagues have created a simple superconducting device that could transfer current through electronic devices much more efficiently than is possible today. As a result, the new diode, a kind of switch, could dramatically cut the amount of energy used in high-power computing systems, a major problem that is estimated to become much worse.

A ’Jupiter’ Hotter than the Sun
A newly discovered binary celestial system may advance our understanding of planet and star evolution under extreme conditions The search for exoplanets - planets that orbit stars located beyond the borders of our solar system - is a hot topic in astrophysics. Of the various types of exoplanets, one is hot in the literal sense: hot Jupiters, a class of exoplanets that are physically similar to the gas giant planet Jupiter from our own neighborhood.
