Information theory, which was developed by Claude Shannon starting in the late 1940s, deals with questions such as how quickly information can be sent over a noisy communications channel. Both the information carriers (e.g., ...
In materials science, achromatic optical components can be designed with high transparency and low dispersion. Materials scientists have shown that although metals are highly opaque, densely packed arrays of metallic nanoparticles ...
Fiber optic gyroscopes, which measure the rotation and orientation of airplanes and other moving objects, are inherently limited in their precision when using ordinary classical light. In a new study, physicists have experimentally ...
In a new study, researchers have propelled water nanodroplets across a graphene surface at speeds of up to 250 km (155 miles) per hour—which, for comparison, is about twice as fast as a sprinting cheetah. The water droplets' ...
A team of researchers affiliated with institutions in Austria, the U.S. and Switzerland has found evidence of negative emotional contagion in lab ravens. In their paper published in Proceedings of the National Academy of ...
A team of researchers from the University of California and Fudan University has developed a way to use a single molecule magnet as a scanning magnetometer. In their paper published in the journal Science, the group outlines ...
A team of researchers at Cambridge University has replaced the genes of E. coli bacteria with genomes they synthesized in the lab. In their paper published in the journal Nature, the group describes replacing the genome and ...
A team of researchers with the University of Neuchâtel in Switzerland and the University of St Andrews in the U.K., has found evidence of titi monkeys using probabilistic predator calls to alert others in their group to ...
Using NASA's Swift space telescope and NICER instrument aboard the International Space Station (ISS), astronomers have investigated the properties of an ultra-luminous X-ray pulsar known as NGC 300 ULX1. Results of this study, ...
A team of researchers at Utrecht University, the Norwegian University of Science and Technology and the University of Konstanz has recently proposed a new method to determine magnon coherence in solid-state devices. Their ...
