An effective navigation system would improve the mobility of millions of blind people all over the world. A new "eye" developed by scientists in Japan will allow blind people to cross busy roads in total safety for the first time.
The "electronic eye", which would be mounted on a pair of glasses, will be capable of detecting the existence and location of a pedestrian crossing, and at the same time measure the width of the road to the nearest step and detect the colour of the traffic lights. This research appears today (19th November) in the journal Measurement Science and Technology published by the UKs Institute of Physics.
Tadayoshi Shioyama and Mohammad Uddin, from the Kyoto Institute of Technology in Japan, have developed a system that is able to detect the existence of a pedestrian crossing in front of a blind person using a single camera. When combined with two other techniques the authors have produced, for measuring the width of the road and the colour of traffic lights, a single camera can now give the blind all the information they need to cross a road in safety.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
