The sounds of music -- how they are created and the rules of physics they follow -- will be the subject of the May 30 CU Wizards science show for children to be held at the University of Colorado at Boulder. Physics Professor Jim Faller will use a group of homemade instruments to demonstrate various aspects of "The Physics of Music." The instruments will be constructed from a wide range of materials including bamboo, garden hose, plastic pipe, redwood, funnels and doorknobs.

Theresa Hernandez, an associate professor of psychology at the University of Colorado at Boulder, is one of 16 people in the nation selected to participate in a special two-year national security program. The Defense Science Study Group is designed to inform outstanding scientists in their early careers about technical aspects of national security issues, especially in fields that have not traditionally been associated with critical defense needs. It is run by the Institute for Defense Analyses for the U.S. Department of Defense.

The Child Learning Center in the department of speech, language and hearing sciences at CU-Boulder has completed construction of a new classroom loft donated by the Flatirons Kiwanis Club in Boulder. In 1996 the Flatirons and the Foothills Kiwanis Clubs merged and the Flatirons club donated its remaining funds to build the loft in the Child Leaning Center. The loft is in memory of Everett Luce and Les Grote, two former Flatirons Kiwanians who volunteered much of their time and energy to the children at the center.

The University of Colorado at Boulder has been selected by NASA as one of 11 initial members of the space agency's new Astrobiology Institute that will focus on interdisciplinary research regarding life in the universe. The 11 academic and research institutions were selected from 53 proposals submitted to NASA. CU-Boulder's new Center for Astrobiology, which will be headquartered at the Laboratory for Atmospheric and Space Physics under the direction of LASP Research Associate Bruce Jakosky, will be funded by a five-year, $3 million NASA grant.

Excavations of a Pueblo site in the Four Corners region linked to the Chaco culture that once dominated the Southwest indicate the site was still occupied well after the collapse of the ancient empire about 1125.

* The Bluff Great House excavation is a cooperative project involving CU-Boulder, the Southwest Heritage Foundation and Abajo Archaeology, a private contract firm in Bluff. The foundation was begun in June 1994 when Indianapolis businessman Skip Lange purchased the land from a local Bluff resident specifically to support the great house excavations and preservation of the archaeological site. The foundation is a non-profit corporation and contributions are tax-deductible. The National Geographic Society has provided the primary research funding during the past two summers.

The Center for Environmental Journalism at the University of Colorado at Boulder has selected five journalists as Ted Scripps Fellows in Environmental Journalism. They will embark next fall on a two-semester program, taking classes in environmental science and policy and conducting independent research.

Members of the CU Board of Regents have asked the Boulder campus to delay implementation of the revised Sexual Harassment Policy to allow more discussion and consideration of proposed changes in the policy. Specifically, members of the Board asked for more information about the change in regard to amorous relationships between two people where an evaluative relationship exists, and about the addition of the position title "supervisor" to the list of employees who must report alleged incidents of sexual harassment.
