WASHINGTON – The editors of the Proceedings of the National Academy of Sciences (PNAS) have selected six outstanding PNAS papers for the 2007 Cozzarelli Prize, an award for papers that reflect the highest standards of scientific excellence and originality.


The award was established in 2005 as the PNAS Paper of the Year Prize and renamed the Cozzarelli Prize in 2007 to honor late PNAS Editor-in-Chief Nicholas R. Cozzarelli. The annual award acknowledges papers published in PNAS during the previous year that reflect exceptional contributions to the scientific disciplines represented by the National Academy of Sciences. The 2007 awards will be presented at the PNAS Editorial Board Meeting on April 27, 2008, in Washington, DC. 


Papers receiving the Cozzarelli Prize were chosen from more than 3,600 research articles published by PNAS in 2007 and represent the six broadly defined classes under which the National Academy of Sciences is organized.
