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.

NASA Invites Public to Join #SkyScience Cloud Study

NASA is inviting people everywhere to become cloud-studying citizen scientists during Earth Science Week, Oct. 12-18. Credit: NASA NASA is inviting people around the globe to step outside during Earth Science Week, Oct. 12-18, observe the sky and share their observations as citizen scientists. NASA’s #SkyScience activity is part of an annual educational event organized by the American Geosciences Institute to encourage the public to engage in Earth sciences. Citizen scientists can participate in this global Earth science data collection event by observing, photographing and reporting on clouds over their location as a NASA satellite passes over. Reports and photos…
