Looking for an alternative, University of Arizona researchers in the College of Agriculture and Life Sciences began collecting native saltgrass plants from open areas in Colorado in 1995, and have been testing them for possible turf cultivation in Arizona.
An ancient drainage basin and aquifer system lies hidden and deformed in one of the most geologically dynamic landscapes on Mars, a UA-led team of scientists reports. Parts of the basin -- about the size of the United States -- may harbor near-surface water and possibly life.
UA scientists have made an ultra lightweight demonstration space mirror that could be developed for satellites in geosynchronous orbit and for giant space telescopes.
The search for extraterrestrial intelligence is taking some new turns. SETI Director Jill Tarter will talk Oct. 11 on "SETI: Science Fact, Not Fiction." Her lecture is free and open to the public.
Just as industry tests products for reliability and safety, cells, too, have evolved their own means of quality control. These mechanisms ensure that cells grow and divide properly so organisms function normally. In the Oct. 4 issue of Nature, University of Arizona scientists Pat Hilleren and Roy Parker reveal a unique mechanism of quality control in gene expression.
Jupiter's moon Io has pulled a surprise on NASA's Galileo spacecraft, hurling up the tallest volcanic plume ever seen, which arose from a previously unknown volcano.
A pilot study by LTRR research specialists David Meko and Christopher Baisan on Arizona's San Pedro watershed indicates tree ring analysis can successfully pinpoint years when the monsoon failed to bring its summer rains to the Southwest.
Students become environmental detectives to discover why fish are dying. The Gray Area site is fictitious - but the research experience is real, relevant and a great way to teach science, teachers say.
Italgas, a leading supplier of natural gas in Italy and Europe, has awarded a University of Arizona chemist a 2001 Italgas Prize for Research and Technological Innovation. Jean-Luc Br
University of Arizona researchers have received a $900,000 National Science Foundation grant to set up a web-based library of articles relating to civil engineering technologies. Users will be able to customize the database for different audiences, such as K-12, college students, engineers, and news reporters.
