Listening to quantum radio

Researchers at Delft University of Technology have created a quantum circuit to listen to the weakest radio signal allowed by quantum mechanics. This new quantum circuit opens the door to possible future applications in areas ...

New theory overcomes a longstanding polymer problem

All polymers have a distinctive degree of elasticity—how much they will stretch when a force is applied. However, for the past 100 years, polymer scientists have been stymied in their efforts to predict polymers' elasticity, ...

Sea level rise: Jeopardy for terrestrial biodiversity on islands

Model calculations predict a sea level rise of about one meter by the end of this century and of up to five and a half meters by the year 2500. Until now there are few studies on the potential impacts of a rising sea level ...

Tablet as teacher: Poor Ethiopian kids learn ABCs

(AP)—The kids in this volcano-rim village wear filthy, ragged clothes. They sleep beside cows and sheep in huts made of sticks and mud. They don't go to school. Yet they all can chant the English alphabet, and some can ...

Powering lasers through heat

In micro electronics heat often causes problems and engineers have to put a lot of technical effort into cooling, for example micro chips, to dissipate heat that is generated during operation. Austrian physicists have now ...

Next-generation echo sounder ready

Norwegian researchers are putting the finishing touches on a new echo sounder that provides far more information than previous versions ever could – making it much easier to identify fish and zooplankton.
