Survivor of stellar collision is new type of pulsating star
A team of astronomers from the UK, Germany and Spain have observed the remnant of a stellar collision and discovered that its brightness varies in a way not seen before on this rare type of star. By analysing the patterns in these brightness variations, astronomers will learn what really happens when stars collide.

Making hydrogenation greener
Researchers from McGill University, RIKEN (The Institute of Physical and Chemical Research, Wako, Japan) and the Institute for Molecular Science (Okazaki, Japan) have discovered a way to make the widely used chemical process of hydrogenation more environmentally friendly - and less expensive. Hydrogenation is a chemical process used in a wide range of industrial applications, from food products, such as margarine, to petrochemicals and pharmaceuticals.

Improving Measurements by Reducing Quantum Noise
Researchers from Vienna University of Technology have built a new interferometer for trapped, ultracold atomic gases. By strongly suppressing the quantum noise, which ultimately limits the performance of interferometers, they were able to curb the effect of atomic interactions, and increase the interrogation time of their interferometer.

Nano-thermometer enables first atomic-scale heat dissipation measurements
Nano-thermometer enables first atomic-scale heat dissipation measurements
ANN ARBOR-In findings that could help overcome a major technological hurdle in the road toward smaller and more powerful electronics, an international research team involving University of Michigan engineering researchers, has shown the unique ways in which heat dissipates at the tiniest scales. A paper on When a current passes through a material that conducts electricity, it generates heat.

Controlling magnetic clouds in graphene
Controlling magnetic clouds in graphene
12 Jun 2013 Wonder material graphene can be made magnetic and its magnetism switched on and off at the press of a button, opening a new avenue towards electronics with very low energy consumption. In a report published in Nature , a University of Manchester team led by Dr Irina Grigorieva shows how to create elementary magnetic moments in graphene and then switch them on and off.

Data Highways for Quantum Information
Researchers at the Vienna University of Technology quantum mechanically couple atoms to glass fiber cables. Now, they have shown that their technique enables storage of quantum information over a sufficiently long period of time to realize global quantum networks based on optical fibers. Researchers at the Vienna University of Technology quantum mechanically couple atoms to glass fiber cables.

Plastic electronics made easy
Plastic electronics made easy
Scientists have discovered a way to better exploit a process that could revolutionise the way that electronic products are made. The scientists from Imperial College London say improving the industrial process, which is called crystallisation, could revolutionise the way we produce electronic products, leading to advances across a whole range of fields; including reducing the cost and improving the design of plastic solar cells (see pull-out box).

The Dance of the Atoms
Catalysts can stop working when atoms on the surface start moving. At the Vienna University of Technology, this dance of the atoms could now be observed and explained. Lone people standing in a ballroom don't tend to move a lot. It's only when they find a suitable dance partner that rapid motion sets in.

New phase of matter discovered In superconducting material
New phase of matter discovered In superconducting material
Tiny crystals, probed with a device called a resonant ultrasound spectrometer, are helping solve the long-time mystery of "pseudogap behavior" in copper oxide superconductors. News flash: The pseudogap is indeed a phase of matter.

Using laser-driven neutrons to stop nuclear smugglers
Using laser-driven neutrons to stop nuclear smugglers
Researchers have successfully demonstrated for the first time that laser-generated neutrons can be enlisted as a useful tool in the War on Terror. We have demonstrated for the first time a novel approach for generating a record number of neutrons driven by a laser directed into a beam over a very small area that could provide proof positive of a large variety of nuclear items.

New method of mass-producing high-quality DNA molecules
A new method of manufacturing short, single-stranded DNA molecules can solve many of the problems associated with current production methods. The new method, which is described in the scientific periodical Nature Methods, can be of value to both DNA nanotechnology and the development of drugs consisting of DNA fragments.

A New Kind of Cosmic Glitch
The physics behind some of the most extraordinary stellar objects in the Universe just became even more puzzling. A group of astronomers led by McGill researchers using NASA's Swift satellite have discovered a new kind of glitch in the cosmos, specifically in the rotation of a neutron star. Neutron stars are among the densest objects in the observable universe; higher densities are found only in their close cousins, black holes.

Models from Big Molecules Captured in a Flash
Models from Big Molecules Captured in a Flash
To learn how biological molecules like proteins function, scientists must first understand their structures. Almost as important is understanding how the structures change, as molecules in the native state do their jobs. Existing methods for solving structure largely depend on crystallized molecules, and the shapes of more than 80,000 proteins in a static state have been solved this way.
