UPTON, NY — Sally Dawson, a theoretical physicist at the U.S. Department of Energy's Brookhaven National Laboratory, has been named a recipient of the 2017 J.J. Sakurai Prize for Theoretical Particle Physics. The award, given by the American Physical Society (APS), recognizes Dawson and her three co-authors of The Higgs Hunter's Guide, a seminal book first published in 1989 on the physics of Higgs bosons—fundamental particles predicted by the accepted theory of particle physics as essential to generating the mass of fundamental particles, and discovered in experiments at the Large Hadron Collider (LHC) in 2012.
Understanding how tiny particles emitted by cars and factories affect Earth's climate requires accurate climate modeling and the ability to quantify the effects of these pollutant particles vs. particles naturally present in the atmosphere. One large uncertainty is what Earth was like before these industrial-era emissions began. In a paper just published in Nature, scientists collaborating on the GoAmazon study describe how they tracked particles in the largely pristine atmosphere over the Amazon rainforest, which has given them a way to effectively turn back the clock a few hundred years.

This research-conducted at the University of Connecticut and the U.S. Department of Energy's Brookhaven National Laboratory, and described in the journal Nature Energy-may help explain how a common processing technique turns cadmium telluride into an excellent material for transforming sunlight into electricity, and suggests a strategy for engineering more efficient solar devices that surpass the performance of silicon.
Since 1952, the Department of Energy’s (DOE) Brookhaven National Laboratory has been home to a national resource whose existence is not widely known outside of its customer base: the National Nuclear Data Center (NNDC), a user facility with a research mission. Alejandro Sonzogni, the new director of the NNDC, sees his mission as adapting the NNDC group’s activities to meet the changing needs of the nuclear community and spreading the word about the services the group offers.
