DARPA RadioBio Program Investigates EM-Based Biological Communication

DARPA starts new program to explore whether electromagnetic waves are purposefully transmitted and received within or between cells and, if so, to leverage those insights not just for biosystems but also for communicating in cluttered electromagnetic environments. For decades scientists have wondered whether electromagnetic waves might play a role in intra- and inter-cell signaling. Researchers

Plasmons Call the Tune in New Graphene-Based Terahertz Laser

A new type of semiconductor laser has been created using the unique electronic properties of graphene. Designed in the UK by researchers at the University of Manchester, the prototype operates in the terahertz band and can be easily tuned to output radiation at specific wavelengths. The team says that its research could lead to the
