Making the switch to polarization diversity

Vast amounts of data transmit across the Internet and telecommunications networks delivering, for example, real-time video calls from one cell phone to another - across the world. As people send and receive increasing amounts ...

Bacteria recruit other species with long-range electrical signals

Biologists at UC San Diego who recently found that bacteria resolve social conflicts within their communities and communicate with one another like neurons in the brain have discovered another human-like trait in these apparently ...

Scientists discover a key signal in intercellular communication

A team of scientists at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC), led by Prof. Francisco Sánchez-Madrid, has characterized a cell signal that impedes intercellular communication and could ...

Chaos could provide the key to enhanced wireless communications

Chaos, somewhat ironically, has one clear attribute: random-like, apparently unpredictable, behavior. However recent work shows that that unpredictable behavior could provide the key to effective and efficient wireless communications.

Ultracompact photodetector for optical data transmission

Data traffic is growing worldwide. Glass-fiber cables transmit information over long distances at the speed of light. Once they have reached their destination, however, these optical signals have to be converted into electrical ...

New optical transmitter enables better communication networks

All the world's data – pictures, video, sounds, and text – has to traverse complex networks of optical fibers that crisscross cities, regions, and countries. To better handle the glut of information, a research team from ...
