'Comb on a Chip' Powers Atomic Clock Design

July 23, 2014 | by Laura Ost, NIST | News | Comments

Researchers from NIST and Caltech have demonstrated a new design for an atomic clock that is based on a chip-scale frequency comb/microcomb. The microcomb clock is the first demonstration of all-optical control of the microcomb, and its accurate conversion of optical frequencies to lower microwave frequencies.

Carbyne Morphs When Stretched

July 22, 2014 10:18 am | by Mike Williams, Rice University | News | Comments

Until recently, carbyne has existed mostly in theory, though experimentalists have made some headway in creating small samples of the finicky material. The carbon chain would theoretically be the strongest material ever, if only someone could make it reliably.

A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells. A new study from MIT materials scientists reveals that these nanoparticles enter cells by taking advantage of a route normally used in vesicle-vesicle fusion, a crucial process that allows signal transmission between neurons.


Tiny Laser Sensor Heightens Bomb Detection Sensitivity

July 21, 2014 11:51 am | by Sarah Yang, UC Berkeley Media Relations | News | Comments

New technology under development at UC Berkeley could soon give bomb-sniffing dogs some serious competition. A team of researchers has found a way to dramatically increase the sensitivity of a light-based plasmon sensor to detect incredibly minute concentrations of explosives. The researchers note that the sensor could potentially be used to sniff out a hard-to-detect explosive popular among terrorists.
