Caltech Scientists Identify Electronic “Noise,” Discovery Could Change Electronics

Cross-sectional image of ultra-low noise InP transistor. Electrons, accelerated in the high mobility channel under the 100-nanometer gate, collide and dissipate heat that fundamentally limits the noise performance of the transistor. Credit: Illustration courtesy of…

Why Antarctic Polar Ice is Melting: Robotic Ocean Gliders Discover Impact of Eddies

Credit: UEA/Caltech Credit: Andrew Thompson/Caltech The rapidly melting ice sheets on the coast of West Antarctica are a potential major contributor to rising ocean levels worldwide. Although warm water near the coast is thought to…

Mars Rover Technology Adapted to Detect Gas Leaks

This artist’s concept features NASA’s Mars Science Laboratory Curiosity rover, a mobile robot for investigating Mars’ past or present ability to sustain microbial life. Image credit: NASA/JPL-Caltech In collaboration with NASA’s Jet Propulsion Laboratory in Pasadena, California, Pacific Gas and Electric Company (PG&E) announced that it is testing state-of-the-art technology adapted from NASA’s Mars rover program. Originally designed to find methane on the Red Planet, this laser-based technology is lightweight and has superior sensitivity to methane, a major component of natural gas. The technology applied back on Earth helps guide PG&E crews using a tablet interface to identify possible leak…
