New research data from scientists at USC San Diego suggests that the human exosome maintains progenitor cell function, functioning as a surveillance system in cells to regulate the normal turnover of RNAs as well as to destroy RNAs with errors in them. In the July 6 issue of Cell Stem Cell, researchers at the University […]

DARPA Uses Cold Plasma to Suppress and Extinguish Fire

DARPA Researches Cold Plasma to Fight Fires

Working on innovative approaches to firefighting, DARPA has been exploring technologies to manipulate and extinguish flames using physics. They were able to suppress fire using electromagnetic and acoustic waves that interact with the plasma of the flames, instead of the traditional approach of interfering with chemical reactions used in combustion. Fire in enclosed military environments […]

Repeating Patterns Dictate Optical Properties of Nanoparticle Arrays

parallels between nanoparticle arrays and polymers

A newly published study from scientists at Rice University found patterns in the way that surface plasmons influence each other in chains of gold nanoparticles. New research at Rice University that seeks to establish points of reference between plasmonic particles and polymers might lead to smaller computer chips, better antennae and improvements in optical computing. […]

Optically Switchable Chiral THz Metamolecules

Optically Switchable Chiral Terahertz Metamolecules

Using terahertz metamaterials engineered from nanometer-sized gold strips with air as the dielectric, a team of scientists have created the first artificial molecules whose chirality can be rapidly switched from a right-handed to a left-handed orientation with a beam of light. A multi-institutional team of researchers that included scientists with the U.S. Department of Energy’s […]
