Technologies based on the manipulation of electrons and, increasingly, photons

Only a few decades ago, finding a particular channel on the radio or television meant dialing a knob by hand, making small tweaks and adjustments to hone in on the right signal. Of course, we now take such fine tuning for granted, simply pressing a button to achieve the same effect. This convenience is enabled by radio frequency synthesis, the generation of accurate signal frequencies from a single reference oscillator.
The Direct On-Chip Digital Optical Synthesizer (DODOS) program seeks to create a technological revolution in optical frequency control analogous to the disruptive advances in microwave frequency control in the 1940s.
The RadioBio program aims to establish whether functional signaling via electromagnetic waves between biological cells exists and, if it does, to determine what mechanisms are involved and what information is being transferred. The program seeks to determine the validity of electromagnetic biosignaling claims and, where evidence exists, understand how the structure and function of these natural “antennas” are capable of generating and receiving information in a noisy, cluttered electromagnetic environment.
