Scientists cut ‘Gordian knot’ in human genome

A team of researchers co-led by Erez Lieberman Aiden of Rice University and Baylor College of Medicine has discovered how mysterious, inactive genes in females hold sway over the superloops that connect DNA sequences at opposite ends of the chromosome. The work by Aiden and colleagues at Florida State University and the Broad Institute of …

DARPA has a new vacuum power amplifier which was demonstrated at 0.85 terahertz

The submillimeter wave, or terahertz, part of the electromagnetic spectrum falls between the frequencies of 0.3 and 3 terahertz, between microwaves and infrared light. Historically, device physics has prevented traditional solid state electronics (microchips) from operating at the terahertz scale. Unlocking this band’s potential may benefit military applications such as data rate communications, improved radar …
