Scientists in London have developed an algorithm-based decoder system that enables wheelchair users to move around simply by looking to where they wish to travel. The researchers at Imperial College London say the system is inexpensive and easy to use and could transform the lives of people who are unable to use their limbs.
Algorithms working with inexpensive software could help quadriplegics steer wheelchairs simply by looking in their desired direction of travel. An Imperial College London team says their newly devised system can read eye movements to tell if a person is merely gazing or wants to move. Co-designer and student Kirubin Pillay says it’s simple to use.

The theory has long been touted as the best hope for a unified “theory of everything,” bringing together the physics of the vanishingly small and the mindbendingly large. But it has also been criticized and even ridiculed for failing to make any predictions that could be checked experimentally. It’s not just that we don’t have big enough particle accelerators or powerful enough computers; string theory’s most vocal critics charge that no experiment could even be imagined that would prove it right or wrong, making the whole theory effectively useless.
Now, physicists at Imperial College London and Stanford University have found a way to make string theory useful, not for a theory of everything, but for quantum entanglement.
“We can use string theory to solve problems in a different area of physics,” said theoretical physicist Michael Duff of Imperial College London. “In that context it’s actually useful: We can make statements which you could in principle check by experiment.” Duff and his colleagues describe their findings in a paper in Physical Review Letters September 2.
String theory suggests that matter can be broken down beyond electrons and quarks into tiny loops of vibrating strings. Those strings move and vibrate at different frequencies, giving particles distinctive properties like mass and charge. This strange idea could unite all the fundamental forces, explain the origins of fundamental particles and connect Einstein’s general relativity to quantum mechanics. But to do so, the theory requires six extra dimensions of space and time curled up inside the four that we’re used to.

A new invisibility cloak for data can make information vanish by creating holes in time, new research suggests.
The researchers, who describe their work today (June 5) in the journal Nature, found that by tweaking the optical signals in telecommunications fibers, they created a way to essentially mask data sent between a sender and a receiver to outside observers. This isn’t the first time researchers have taken a page from Harry Potter: Last year, scientists also demonstrated a similar invisibility cloak.
But the new “time cloak” can create many time holes in rapid succession, which means masked data could be sent at commercial data speeds, said Martin McCall, a theoretical-optics researcher at Imperial College London who was not involved in the study.

Scientists demonstrate how they have have created, a new invisibility technique that doesn’t just cloak an object (like in Harry Potter books and movies), but masks an entire event. It is a time masker that works by briefly bending the speed of light around an event.
