National Science Foundation President Award 2005--- 2006


award


Reporters who would like to cover the awards ceremony, should call the White House Office of Media Affairs at 202-456-6238 by COB, Thursday, July 26, 2007 to request clearance. If you have any further questions, please contact: Kristin Scuderi at 202-456-6124.


President George W. Bush will award the National Medals of Science and National Medals of Technology, honoring the nation's leading researchers, inventors and innovators at a ceremony at the White House on Friday, July 27, 2007, at 1:40 p.m.


The National Science Foundation (NSF) administers the prestigious award program, which was established by Congress in 1959. It honors individuals for pioneering scientific research in a range of fields, including physical, biological, mathematical, social, behavioral and engineering sciences, that enhances our understanding of the world and leads to innovations and technologies that give the United States its global economic edge. NSF Director Arden L. Bement will attend the White House ceremony.


The 2006 National Medal of Science Laureates:

Ralph A. Alpher - The Dudley Observatory, Schenectady, NY
For his unprecedented work in the areas of nucleosynthesis, for the prediction that universe expansion leaves behind background radiation, and for providing the model for the Big Bang theory.


Gordon H. Bower - Stanford, Calif.
For his unparalleled contributions to cognitive and mathematical psychology, for his lucid analyses of remembering and reasoning, and for his important service to psychology and American science.


Bradley Efron - Stanford University, Stanford, Calif.
For his contributions to theoretical and applied statistics, especially the bootstrap sampling technique; for his extraordinary geometric insight into nonlinear statistical problems; and for applications in medicine, physics, and astronomy.


Anthony S. Fauci - National Institutes of Health, Washington, D.C.
For pioneering the understanding of the mechanisms whereby the human immune system is regulated, and for his work on dissecting the mechanisms of pathogenesis of human immunodeficiency virus (HIV) that has served as the underpinning for the current strategies for the treatment of HIV disease.


Tobin J. Marks - Northwestern University, Evanston, Ill.
For his pioneering research in the areas of homogeneous and heterogeneous catalysis, organo-f-element chemistry, new electronic and photonic materials, and diverse areas of coordination and solid state chemistry.


Lonnie G. Thompson - Ohio State University, Columbus, Ohio
For his pioneering research in paleoclimatology analyzing isotopic and chemical fingerprints found in tropical ice cores from the world's highest mountain glaciers and for his courage in collecting these disappearing climate archives that has transformed our understanding of the natural and anthropogenic factors influencing climate variability on our planet, past and present.


Torsten N. Wiesel - The Rockefeller University, New York, NY

An Exoplanet With Liquid Water?


An Exoplanet With Liquid Water?


European astronomers say they have detected a distant Earth-like planet with conditions that might allow liquid water to exist. The discovery was made using the European Southern Observatory's 3.6-m telescope and the High Accuracy Radial Velocity for Planetary Searcher (HARPS) spectrograph.



Twenty light-years away orbiting the red dwarf star Gliese 581, the new exoplanet is the most Earth-like discovered to date, with a radius only 50 percent larger than the Earth and with temperatures that would allow water to exist in a liquid state.


"We have estimated that the mean temperature lies between 0 and 40 degrees Celsius, and water would thus be liquid," explains Stéphane Udry, from the Geneva Observatory. "Moreover, its radius should be only 1.5 times the Earth's radius, and models predict that the planet should be either rocky - like our Earth - or covered with oceans."


The new planet's host star, Gliese 581, is among the 100 closest stars to us, located only 20.5 light-years away in the constellation Libra. It is only one third the mass of our sun and is much cooler. Thanks to being just 7 million miles away, the planet completes a full orbit of the star in just 13 days.


Reporting their discovery in Astronomy and Astrophysics, the astronomers said that red dwarfs were ideal targets for the search for low-mass planets where water could be liquid. "Because such dwarfs emit less light, the habitable zone is much closer to them than it is around the Sun," noted Xavier Bonfils, from Lisbon University. "Planets lying in this zone are more easily detected with the radial-velocity method, the most successful technique devised for detecting exoplanets."


French astronomer Xavier Delfosse added that the importance of liquid water could not be underestimated in the search for extraterrestrial life. "Because of its temperature and relative proximity, this planet will most probably be a very important target of the future space missions dedicated to the search for extra-terrestrial life. On the treasure map of the Universe, one would be tempted to mark this planet with an X."
