Johanna L. Miller DOE labs pitch major AI R&D initiative to Congress Leveraging their advanced computing capabilities, national laboratories are laying groundwork for a potential multibillion-dollar initiative to develop artificial intelligence tools for scientific and security applications. Jacob Taylor Live webinar Webinar—Boost Your Signal-to-Noise Ratio with Lock-in Detection New technologies based on smaller and ever-more powerful devices often require precise measurements of tiny signals that are buried in noise. In this tutorial, you will learn how to use lock-in amplifiers and optimize measurement parameters to get the best signal-to-noise ratio. Register now. FROM THE VAULT: March 1986 SQUIDs, Brains and Gravity Waves Superconducting quantum interference devices are so sensitive to magnetic flux that they can map the tiny magnetic fields emanating from the human brain and detect the submicroscopic motions of gravity‐wave detectors. John Clarke Commentary: Why the fascination with Oppenheimer? J. Robert Oppenheimer and the Manhattan Project scientists are a rare example of weapons designers who have gone down in history. Ryan Dahn Lasers help categorize recyclables Combining machine learning with materials science could help clean up our planet.
