How Pulsars Slow Down With Age
October 8, 2012 — Researchers have developed a model which explains how the spin of a pulsar slows down as the star gets older. A pulsar is a highly magnetized rotating neutron star which was formed from the remains ... > full story -
Novel Materials Become Multifunctional at Ultimate Quantum Limit
September 25, 2012 — Physicists have examined the lower limits of novel materials called complex oxides and discovered that unlike conventional semiconductors the materials not only conduct electricity, but also develop ... > full story -
Single-Atom Writer a Landmark for Quantum Computing
September 19, 2012 — Engineers have created the first working quantum bit based on a single atom in silicon, opening the way to ultra-powerful quantum computers of the future. Scientists were able to both read and write ... > full story -
Research Gives Insight Into Graphene-Metal Junctions
September 18, 2012 — Researchers have developed a better understanding of how these graphene-metal interfaces affect the movement of electrons through two-terminal ... > full story -
'Spin' in Media Reports of Scientific Articles
September 11, 2012 — Press releases and news stories reporting the results of randomized controlled trials often contain "spin" -- specific reporting strategies (intentional or unintentional) emphasizing the beneficial ... > full story -
Driving an Electron Spin Vortex 'Skyrmion' With a Microcurrent
August 29, 2012 — Scientists have succeeded in forming a skyrmion crystal, in which electron spin is aligned in a vortex shape, in a microdevice using the helimagnet FeGe, and driving the skyrmion crystal with an ... > full story -
Graphene-Based Materials Kill Bacteria Two Ways
August 29, 2012 — Graphene-based materials kill bacteria through one of two possible mechanisms. Researchers have now compared the antibacterial activity of graphite, graphite oxide, graphene oxide and reduced ... > full story -
Magnetic Vortex Reveals Key to Spintronic Speed Limit
August 28, 2012 — Spintronics use electron spin to write and read information. To mobilize this emerging technology, scientists must understand exactly how to manipulate spin as a carrier of computer code. Now, ... > full story -
