Biocompatible Nanolaser Could Function Inside Living Tissues

A tiny nanolaser that can function inside of living tissues without harming them has been developed by researchers at Northwestern and Columbia Universities. Only 50 to 150 nanometers thick, the laser is about 1/1,000th the thickness of a single human hair. At this size, the laser[1] can fit and function inside living tissues, with the […]

New Discovery Could Enable Portable Particle Accelerators

Conventional particle accelerators are typically gigantic machines that occupy a lot of space. Even at more modest energies, such as that used for cancer therapy and medical imaging, accelerators need large rooms to accommodate the required hardware, power supplies and radiation shielding. But a new discovery by physicists at the University of Maryland could hold […]

Positrons Are Plentiful In Ultra-intense Laser Blasts

A new recipe for using intense lasers to create positrons, the antiparticle of electrons, in record numbers and density, has been found by physicists from Rice University and the University of Texas at Austin. In a series of experiments, the researchers used UT’s Texas Petawatt Laser to make large number of positrons by blasting tiny […]
