Researchers build an all-optical transistor

Researchers build an all-optical transistor | Biosciencia News | Scoop.it
Optical computing — using light rather than electricity to perform calculations — could pay dividends for both conventional computers and quantum computers, largely hypothetical devices that could perform some types of computations exponentially...
Biosciencia's insight:

An optical switch that can be turned on by a single photon could point toward new designs for both classical and quantum computers.

On the hunt for neutrinos

On the hunt for neutrinos | Biosciencia News | Scoop.it
Every second, trillions of particles called neutrinos pass through your body.
Biosciencia's insight:

Physicist Joseph Formaggio seeks new ways to detect and measure the elusive particles. These particles have a mass so tiny it has never been measured, and they interact so weakly with other matter that it is nearly impossible to detect them, making it very difficult to study their behavior.

New Technique ‘Defies’ Laws of Physics

New Technique ‘Defies’ Laws of Physics | Biosciencia News | Scoop.it
Researchers at Argonne National Laboratory, Illinois, have found a way to apply pressure to make a material expand instead of compress.
Biosciencia's insight:

Pressure-induced transitions are associated with near two-fold volume expansions. While an increase in volume with pressure is counterintuitive, the resulting new phases contain large fluid-filled pores, such that the combined solid-fluid volume is reduced and the inefficiencies in space filling by the interpenetrated parent phase are eliminated (Argonne National Laboratory).

'Corkscrew' light could turbocharge Internet

'Corkscrew' light could turbocharge Internet | Biosciencia News | Scoop.it
Different-shaped beams could increase fibre-optic capacity, easing Internet congestion.
Biosciencia's insight:

Twisty beams of light could boost the traffic-carrying capacity of the Internet, effectively adding new levels to the information superhighway, suggests research published today in Science.

Controlling magnetic clouds in graphene | The University of Manchester

Controlling magnetic clouds in graphene | The University of Manchester | Biosciencia News | Scoop.it

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.

Biosciencia's insight:

In a report published in Nature Communications, aUniversity of Manchester team led by Dr Irina Grigorieva shows how to create elementary magnetic moments in graphene and then switch them on and off.
