By constructing a wind screen on the Rhone glacier in Switzerland, cold downwinds, which normally pass unhindered into the valley, can be intercepted and collected, thus creating a cold air cushion at the wind screen and in its close vicinity. 'Our test wind screen set up on the Rhone glacier resulted in a definite cooling of the air near the surface, with the drop in temperature being up to three degrees centigrade,' reported Professor Hans-Joachim Fuchs of the Institute of Geography of the Johannes Gutenberg University Mainz…
The design of new materials with specific properties is an important but demanding challenge in physics and chemistry. Already in 1982 Nobel Prize winner Richard P. Feynman therefore suggested to build a 'quantum simulator' in order to understand and predict the properties of complex materials by simulating them using an artificial, but highly controllable quantum system…
Screening with an ultrasound machine has proved highly successful in preventing stroke among children with sickle cell disease, by identifying children who are then preventively treated with blood transfusions. Over an eight-year period at The Children's Hospital of Philadelphia, researchers found that the technique, transcranial Doppler ultrasonography (TCD), along with regular transfusions for children found to be at high risk, reduced stroke to one-tenth of the incidence found before TCD was introduced…
