Boffins develop automatic troll slaying

Wikia_HP_-_Mountain_TrollResearchers at Cornell University have come up with a way to identify internet trolls  80 per cent of the time.

The software could create the possibility of creating automated methods to spot and auto-ban forum and comment-thread trolls.

Justin Cheng, Cristian Danescu-Niculescu-Mizil and Jure Leskovec submitted the paper Antisocial Behaviour in Online Discussion Communities [PDF], which details the findings from an 18-month study of banned commenters over three high-traffic communities: news giant cnn.com, political hub breitbart.com and the vocal gaming communities at ign.com.… Read the rest

Graphene spins like nothing else on earth

illustration courtesy Chalmers University of TechnologyScientists at Chalmers University of Technology said that large area graphene preserves electronic spin over a long period.

And that means the window is now open for the long-touted spintronics, promising faster CPUs and memory for computers.

The aptly named Saroj Dash, head of the research group at Chalmers, said: “These results will attract a lot of attention in the research community and put graphene on the map for applications in spintronic components.”

Spintronics, already used in state of the art hard drives but Dash believes there’s more exciting times ahead.… Read the rest

Futuristic Intel chips under the bonnet of supercomputer

tm40-whirlwindA supercomputer being installed in the Argonne National Laboratory will have more than 70 core Knight’s Hill architecture and some other fairly sexy interconnect.

According to the Platform the project – dubbed “Aurora” – will be the first time in 20 years that a chipmaker, as opposed to a systems vendor, has been awarded the contract to build a leading-edge national computing resource.… Read the rest

Scientists make battery breakthrough

lithium-ion batteryA group of researchers at Stanford University claim to have invented an aluminium battery that will spell the end of lithium-ion batteries.

The batteries are made of a mix of graphite and aluminium and the Stanford scientists said that commercial production of the new style batteries could charge a smartphone in less than a minite.… Read the rest

Boffins uses lasers to make fruit flies moonwalk

Boffins from the Vienna University of Technology and US researchers have hatched out a plan to control fruit flies with lasers.

We are not sure of what inspired someone from a university to think “the world would be a better place if we could control fruit flies” and then to think “what would happen if I fried the beggars with a laser”.… Read the rest

Flexible computing hits the right vein

Researchers at the University of Texas at Dallas have emerged from their smoke filled labs with a circuit board made with thin film transistors that are flexible enough to wrap around a nerve or blood vessel.

According to a paper issued by the team, they managed to laminate shape-memory polymers on top of thin film transistor circuits to create a chip that’s rigid at room temperature, but becomes pliant and flexible at body temperatures.… Read the rest
