Less Radiation in Inner Van Allen Belt Than Previously Believed

VABprobes-NASA.jpeg

The inner Van Allen belt has less radiation than previously believed, according to a recent study in the Journal of Geophysical Research. Observations from NASA’s Van Allen probes show the fastest, most energetic electrons in the inner radiation belt are actually much rarer and harder to find than scientists expected. This is good news for spacecraft that are orbiting in the region and can be damaged by high levels of radiation.

‘Flying Saucer’ Colloidal Quantum Dots Produce Brighter, Better Lasers

LeadImage_KevinSoobrian.1.jpg

A multi-institutional team of researchers from Canada and the US has demonstrated steady state lasing with solution-processed nanoparticles called “colloidal quantum dots,” an important step on the path to improving laser tools for fiber optics, video projectors and more accurate medical testing technology. The work is reported today in a paper for the journal Nature.
