Machine learning, harnessed to extreme computing, aids fusion energy development

Simulations of plasma turbulence at different locations inside the SPARC tokamak, currently under design. The color bar indicates the predicted temperature of the plasma. Credit: Plasma Science and Fusion Center MIT research scientists Pablo Rodriguez-Fernandez and Nathan Howard have just completed one of the most demanding calculations in fusion science—predicting the temperature and density profiles … Read more

Unexpected light behavior may be harnessed to improve optical communications and sensors

The NIST team directed light into an ultrathin layer of silicon nitride etched with grooves to create a diffraction grating. If the separation between the grooves and the wavelength of light is carefully chosen, the intensity of light declines much more slowly, linearly rather than exponentially. Credit: S. Kelley/NIST Shine a flashlight into a murky … Read more
