The University of Colorado at Boulder's 2005 Homecoming begins Friday, Oct. 7, at 5 p.m. with a Homecoming Parade on University Hill. The parade will feature about 35 floats from CU-Boulder residence halls, student groups, Greeks and the community at large. It will be led by Interim CU-Boulder Chancellor Phil DiStefano and Honorary Grand Marshall Jeremy Bloom. A CU pep rally will follow the parade at Norlin Quad at about 6 p.m. Members of the CU football team will be present for the pep rally.

A University of Colorado at Boulder team has developed the first computer-generated model of a tiny, waterwheel-like molecular rotor that has been harnessed to rotate in one direction at different speeds in response to changes in the strength of an electrical field applied from the outside.

Stein Sture, associate dean for research at the University of Colorado at Boulder's engineering college, has been appointed interim dean of CU-Boulder's Graduate School and vice chancellor for research. Sture's appointment fills positions vacated by Susan Avery, formerly CU-Boulder's top research official. Avery recently was appointed CU-Boulder's interim provost and executive vice chancellor for academic affairs by Interim Chancellor Phil DiStefano.

A new version of the Faculty Course Questionnaire will be distributed to University of Colorado at Boulder students to provide ratings and feedback on classes and instructors beginning with the fall 2006 semester. Highlights of the revised form and evaluation procedure include slightly different questions and a numerical rating scale instead of letter grades.

The Colorado Ethics and Compliance Exchange will examine the implications of new federal laws and guidelines for corporations at its fall meeting on Friday, Oct. 21, at 7 a.m. at the Brown Palace Hotel in Denver.

University of Colorado President Hank Brown: "I congratulate John Hall for receiving the Nobel Prize for his extraordinary contributions. The importance of a laboratory like JILA and a partnership with NIST can not be underestimated. The longstanding partnership between NIST and CU has over the years elevated the university's status as a premiere teaching and research university. What many people do not know, is that this important relationship allows CU students to work directly with Nobel laureates, of which CU now has four."

John L. Hall, a fellow and senior research associate at JILA, a joint institute of the University of Colorado at Boulder and the National Institute of Standards and Technology, has been awarded the 2005 Nobel Prize in Physics. Hall, 71, shared the Nobel with Theodor W. Hänsch of the Max Planck Institute for Quantum Optics and a professor of physics at Ludwig Maximilians University in Munich, Germany, and Roy J. Glauber, a professor of physics at Harvard University.

Neal Lane, White House science adviser to former President Bill Clinton from 1998 to 2001, will speak at the University of Colorado at Boulder on Wednesday, Oct. 5, at 7 p.m. in room 1B50 of the Eaton Humanities Building. The free, public event is part of a yearlong lecture series titled "Policy, Politics and Science in the White House: Conversations with Presidential Science Advisers," sponsored by CU-Boulder's Center for Science and Technology Policy Research.
