An internationally known archaeologist and celebrated storyteller will share his knowledge of the ancient people and pottery of the southwestern United States and the Philippines during a Jan. 25 free public lecture and slide presentation at the University of Colorado at Â鶹ӰԺ. William Longacre, who was honored by the American Anthropological Association as the Distinguished Archaeologist of 2001, will make his presentation at 4 p.m. in room 270 of the Hale Science Building. He is the 2003 CU-Â鶹ӰԺ Department of Anthropology Distinguished Archaeologist.

University of Colorado at Â鶹ӰԺ astronomers have discovered what they believe to be dozens of potential stellar cocoons within a giant star-forming region that may harbor disks of dust and gas that could one day form planetary systems. "This is the first large population of so-called 'proplyd' objects to be found outside of the Orion Nebula, the closest region to Earth known to be forming massive stars," said CU-Â鶹ӰԺ postdoctoral researcher Nathan Smith of the Center for Astrophysics and Space Astronomy.

Time travel and antimatter are often the subjects of sci-fi fantasy, but the real physics behind these and other concepts will be discussed Jan. 11 when the University of Colorado at Â鶹ӰԺ physics department presents its free Saturday Physics Series lecture. "Time Traveling with Physics," a presentation by Professor Patricia Rankin, will begin at 2 p.m. in room G1B20 of the Duane Physics and Astrophysics building on the CU-Â鶹ӰԺ campus.

When Earth's sun expands into a red giant star in roughly five billion years, long after Earth has become uninhabitable, the hydrogen core will be burned out and the bloated outer shell will be cool and murky.

Carlos García, director of the University Memorial Center at the University of Colorado at Â鶹ӰԺ, has been elected to a two-year term as member-at-large of the Board of Trustees for the Association of College Unions International. The appointment begins in March 2004 at the conclusion of the annual national conference in Washington, D.C.

The connections between work, energy, heat and temperature will be explained during the Saturday, Jan. 18, CU Wizards show on "Heat, Temperature and Absolute Zero." Paul Beale, a physics professor at the University of Colorado at Â鶹ӰԺ, will present the show at 9:30 a.m. in Duane Physics room G1B30. The show, aimed primarily at students in grades five through nine, is free and open to the public.

Habitat loss in the West and what people can do about it will be addressed by CU-Â鶹ӰԺ Assistant Professor Sharon Collinge as part of the Chancellor's Community Lecture Series on Wednesday, Jan. 15. Her talk will be from 7 p.m. to 8:30 p.m. in the Chautauqua Community House at 900 Baseline Road in Â鶹ӰԺ and is free and open to the public. No reservations are required.

University of Colorado at Â鶹ӰԺ researchers have found, ironically, that two pollutants -- carbon dioxide and hydrocarbons emitted from agricultural forest trees -- offset each other somewhat in mitigating air quality problems. Carbon dioxide, believed by scientists to be a major factor in greenhouse warming, has been shown to reduce "agriforest" emissions of hydrocarbons that contribute to ground-based ozone pollution, according to CU-Â鶹ӰԺ doctoral candidate Todd Rosenstiel of the environmental, population and organismic, or EPO, biology department.

Students who pursue careers in advertising at the University of Colorado at Â鶹ӰԺ have the opportunity to learn from Kendra Gale, a new assistant professor with extensive advertising industry experience. Gale teaches advertising research and advertising campaign classes at the school of journalism and mass communication and hopes to add courses in account planning and advertising strategy to the advertising sequence.

Two University of Colorado at Â鶹ӰԺ faculty have been elected Fellows of the prestigious American Association for the Advancement of Science for 2002. Professor Michael Breed of CU-Â鶹ӰԺ's environmental, population and organismic biology department was cited for his pioneering research on nest-mate recognition mechanisms in social insects that have illuminated the understanding of kin selection as a potential force in evolution.
