Using graphene, internet connection speeds could be tens of times faster

A collaboration between the Universities of Manchester and Cambridge, which includes Nobel Prize winning scientists Professor Andre Geim and Professor Kostya Novoselov, has discovered a crucial recipe for improving characteristics of graphene devices for use as photodetectors in future high-speed optical communications.

Scientists put a new spin on traditional information technology

Scientists have proposed a new communications scheme that would use silicon wires carrying a constant current to drive electrons from a transmitter to a receiver. By changing its magnetization, a contact would inject electron spin (either up or down) into the current at the transmitter end.

Magnetic memories manipulated by voltage, not heat

In their search for smaller, faster information-storage devices, physicists have been exploring ways to encode magnetic data using electric fields. One advantage of this voltage-induced magnet control is that less power is needed to encode information than in a traditional system.

Rush hour in a coffee stain

A remarkable effect never witnessed before has been discovered in the ring-shaped stains of tiny dissolved particles ('coffee stains') that develop after a liquid has evaporated. While the particles on the outside of the ring are neatly organized, chaos reigns on the inside of the ring where the particles seem to have collected in a great hurry.

A new spin on topological insulator surfaces

A European team of researchers has discovered that properties of the so-called topological insulator bismuth selenide could provide the solution to how a ground-breaking new computing technology called 'spintronics' can work at room temperature. This is a solution scientists have been waiting for ever since the technology was predicted more than two decades ago.
