Washington — President Bush announced on Monday the recipients of the 2007 National Medal of Science and the 2007 National Medal of Technology and Innovation, the country’s highest honors for scientific achievement. Nine academics were among the winners.

But the list of laureates did not come with a corresponding list of citations, and officials of the National Science Foundation, which administers the awards, told The Chronicle that it might take the White House “several more weeks” to release them.

The same NSF officers said the winners of the 2008 medals would be selected this year. In 2007 the White House named the winners of the 2005 and 2006 National Medals.

The academics who will receive a National Medal of Science for their scientific achievements, during a ceremony at the White House on September 29, are:

Fay Ajzenberg-Selove, a professor of physics at the University of Pennsylvania.

Mostafa A. El-Sayed, a professor of chemistry and director of the Laser Dynamics Laboratory at the Georgia Institute of Technology.

Leonard Kleinrock, a distinguished professor of computer science at the University of California at Los Angeles.

Robert J. Lefkowitz, a Howard Hughes Medical Institute investigator at the Duke University Medical Center.

Bert O’Malley, the chair of molecular and cellular biology at Baylor College of Medicine.

Charles P. Slichter, a research professor of physics and emeritus professor of physics and chemistry at the University of Illinois at Urbana-Champaign’s Center for Advanced Study.

Andrew J. Viterbi, a benefactor of and engineering chair at the University of Southern California.

Two professors will received the National Medal of Technology and Innovation for their achievements:

Adam Heller, a research professor of chemical engineering at the University of Texas at Austin.

Carlton Grant Willson, a professor at the University of Texas at Austin.
