Since 1923, the ACS has acknowledged groundbreaking chemists with the award.. ACS titles Chemistry Nobel Laureate while champion of 2011 Priestley Medal Ahmed H. Zewail, Ph.D., 1999 Chemistry Nobel Laureate and Linus Pauling Professor of Chemistry & Professor of Physics at the California Institute of Technology, has been named champion of the 2011 Priestley Medal by the American Chemical Society . The award recognizes Zewail’s revolutionary methods for developing ‘ultraslow-movement’ imaging for the study of ultrafast processes in chemistry, biology and materials science. His work offers deep new insights into components behavior and biological procedures that determine disease and health.Ebbeling, Ph.D., Henry A. Feldman, Ph.D., Virginia R. Chomitz, Ph.D., Tracy A.

Ludwig, M.D., Ph.D.: A Randomized Trial of Sugar-Sweetened Adolescent and Beverages Body Weight The consumption of sugar-sweetened beverages among adolescents1 has increased in tandem with the prevalence of pediatric obesity in the United States,2 suggesting a causal relationship. At the moment, a substantial proportion of high-school students consume sugar-sweetened beverages, including carbonated soda, sports drinks, energy drinks, and sweetened coffees and teas highly.3 Sugar-sweetened beverages will be the leading source of added sugars in the dietary plan of an array of racial and ethnic groups.4 According to nationally representative data, obese and overweight adolescents obtain more than 300 kcal per day from these products, amounting to an average of 15 percent of their total daily energy intake.5 Short-term feeding studies also show better energy intake and excess weight gain with the intake of sugar-sweetened beverages than with drinks containing artificial sweeteners,6 and potential observational studies show positive associations with the chance of obesity and related complications.7 However, the findings from the relatively few randomized, controlled trials designed to examine the effects of sugar-sweetened drinks on body weight have got not been conclusive,8-10 and the use of public wellness measures to reduce the consumption of sugar-sweetened beverages remains controversial.11,12 We previously conducted a 6-month pilot research10 involving normal-weight, overweight, and obese adolescents who consumed sugar-sweetened drinks habitually.
