Research carried out by scientists at the University of Surrey could lead to a significant decrease in the number of pedestrians and cyclists killed each year on Europe’s roads. In-car systems have significantly improved safety for drivers and passengers, and the introduction of soft bumpers and pop-up bonnets has lowered the risk of injury to pedestrians and cyclists, but a system of new sensors currently being developed, could potentially lower the fatality rate even further.
Over 6000 pedestrians and cyclists (Vulnerable Road Users – VRUs) are killed annually on EU roads, this is approximately 25% of all road deaths. In the UK 71% of VRU fatalities occurred at impact speeds under 40mph and 85% of fatalities were injured by the front of the vehicle involved. Deploying external airbags at the front of vehicles could reduce these figures significantly, but a sensor system must be developed to ensure correct and safe deployment.
Scientists believe that a system combining new infrared thermal sensing technology with a high resolution radar could be the answer, since the combination distinguishes VRUs through body heat and not body shape. The system would be able to sense walking adults and children as well as wheelchair users and babies in buggies, as it is not reliant on recognising a pre-set ‘human’ shape but the body heat of the individual. This would then enable the radar system to track the subject and deploy a safety system just before impact. Trials have already taken place using a new. advanced ‘crash test dummy’, which not only has the usual physical properties of such dummies, but also has a human-like heat image.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
