Hippopotamuses are rather vocal animals. Their “wheeze honk” calls can be heard over long distances, leading researchers to suspect the calls play an important role…
Led by the University of Plymouth, UK, and Freie Universität Berlin, Germany, the study analyzed the behavior of 376 children aged five to eight from…
Voices of reason? Study links acoustic correlations, gender to vocal appeal. What makes a voice attractive? The question is the subject of broad interest, with…
Innovation can be used with existing hardware, requires only a software update. A group of researchers led by a BYU computer engineering professor has created…
Data centers are processing data and dispensing the results at astonishing rates and such robust systems require a significant amount of energy — so much…
The slower the better when it comes to light and sound in silicon chips. Integrated circuits in silicon enable our digital era. The capabilities of…
A newly published study reveals that killer whales (Orcinus orca) can engage in cross-species vocal learning, revealing that they shifted the types of sounds they…
By combining several proven technologies that are already widely used in wireless data transmission, engineers from Rice University have created a multiuser, multiantenna scheme to…
Brookhaven National Laboratory researchers are working to develop ways to synchronize the magnetic spins in nanoscale devices to build tiny signal-generating or receiving antennas and…
Researchers from Honeywell International have modified hollow-core fiber, dramatically improving performance and making it the first hollow-core fiber to demonstrate single-spatial-mode, low-loss and polarization control….
A newly published study demonstrates how complex cognitive abilities can be incorporated into electronic systems made with neuromorphic chips. Novel microchips imitate the brain’s information…
New fiber optic technology from researchers at Boston University and the University of Southern California could ease Internet congestion and boost Internet bandwidth. As rapidly…
Quantum encryption systems, which encode signals into a series of single photons, have had trouble sending them along optical fibers. Until now, it has been…
Algebraists are promising to improve wireless bandwidth by an order of magnitude, not by adding base stations, but by using algebra to eliminate the network-clogging…
Max Planck Institute scientists examined the transmission behavior of photonic crystal fibers when they were twisted, finding that the transmission of certain wavelengths becomes much…
In recent experiments, Scientists from the Max Planck Institute and ETH Zurich have transmitted single photons between the smallest antennas in the world, i.e. between…
The SCaN Testbed, or Space Communications and Navigation Testbed, is set to be tested on the International Space Station later this year. During its five…
In the upcoming issue of the journal IEEE Transactions on Information Theory, researchers from MIT, Tel Aviv University and Google prove mathematically and explain a…
