Two films that address the social, health and environmental effects of energy production on the Navajo and Hopi lands will be shown at the UA on Feb. 23, followed by panel discussions with Navajo and Hopi environmental leaders and Arizona energy experts.

The NemaSym Research Coordination Network is an opportunity for scientists to collaborate on nematode research. Understanding the relationship between roundworms and their internal bacteria offers insights on an array of problems, including pest management in agriculture.

UA researchers collaborating with those at Washington State University have found that Google’s PageRank algorithm not only has important applications for webpages, but also water molecules. The team's investigation, recently published in the Journal of Computational Chemistry, found important implications for toxic chemicals.

Two main mirrors of the Large Synoptic Survey Telescope are being built at the UA's Steward Observatory Mirror Lab. Once operational in Chile, the telescope will survey every part of the night sky and detect light from stars becoming supernovas.

Juan M. Restrepo, a UA professor in the departments of mathematics, physics and atmospheric sciences, argues that determining how a population of voters behaves cannot be understood only by studying how individuals vote. He and his colleagues have derived a mathematical model for analyzing the behavior of populations of voters.

An investigation found that refrigerator filters work the best, and some pitcher-style filters work to some degree to remove contaminants. Results of the study are scheduled for publication in the March issue of Good Housekeeping magazine.

A Rube Goldberg competition, a food drive, a talent show, a career fair, plus numerous community outreach events characterize the flavor of this year's E-Week at the UA, Feb. 16-25.

Astronomers are watching the astronomical equivalent of streaming live video of a spectacular outburst from the unstable, behemoth double-star system Eta Carinae, which initially was seen on Earth nearly 170 years ago.

Dengue fever is caused by a virus that is transmitted from person to person by mosquitoes. The UA's Michael Riehle is studying the lifespans of mosquitoes, trying to determine why cases of dengue occur in some geographic areas and not in others.

Involving artists, engineers, foreign language instructors, filmmakers, environmental scholars and new media studies specialists, the Arizona Centennial Project team is developing a new way to see the UA in the history of Arizona’s statehood.

Trying to carve out salt because of the adverse health effects from having too much? Studies by the University of Arizona College of Medicine found that curcumin, the active ingredient in turmeric, helps prevent joint inflammation.
