Miss America speaks about cultural competency

Before an audience of roughly 100 Yale students, faculty, and staff on Feb. 4 in Battell Chapel, Nina Davaluri — Miss America 2014 — shared her goal of spreading cross-cultural understanding and combating ignorance.  

Last September, 24-year old Nina Davaluri became the first woman of South Asian decent to win the Miss America pageant. Following the crowning, some critics called Davaluri a “terrorist” while others stated that she was not “American enough” to represent the United States. Students from the Asian American Cultural Center (AACC) and the South Asian Society (SAS) responded to the racist commentary by organizing a dialogue to promote cross-cultural understanding.  (more…)

Berkeley Lab Researchers Develop New Metrics for X-ray and Neutron Analysis of Flexible Macromolecules

A dramatic leap forward in the ability of scientists to study the structural states of macromolecules such as proteins and nanoparticles in solution has been achieved by a pair of researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab). The researchers have developed a new set of metrics for analyzing data acquired via small angle scattering (SAS) experiments with X-rays (SAXS) or neutrons (SANS). Among other advantages, this will reduce the time required to collect data by up to 20 times.

“SAS is the only technique that provides a complete snapshot of the thermodynamic state of macromolecules in a single image,” says Robert Rambo, a scientist with Berkeley Lab’s Physical Biosciences Division, who developed the new SAS metrics along with John Tainer of Berkeley Lab’s Life Sciences Division and the Scripps Research Institute.
