Faster Photons Could Make Data Totally Secure

Transferring data using light passed along fiber optic cables has become increasingly common over the past decades, but each pulse currently contains millions of photons. That means that in principle, a portion of these could be intercepted without detection. Secure data is already encrypted, but if...

The challenge of miniaturizing devices and systems is also achieving a broader dynamic range of detection for small signals such as sound, vibration, and radio...

Capturing carbon dioxide (CO2) and converting it to useful chemicals such as methanol could reduce both pollution and U.S. dependence on petroleum products. Catalysts are used to bring...

Over the past few years, deep learning algorithms have proven to be highly successful in solving complex cognitive tasks such as controlling self-driving cars and language...
