PipeMedic: Industrial Surgery for Failing Infrastructure

UANews | September 15, 2011
A UA engineering professor's invention helps fix failing pipes that can lead to ruptures that threaten life and property. PipeMedic uses carbon and glass laminates to repair and replace pipelines.

Astronomers Plan Last Look at Asteroid Before OSIRIS-REx Launch

UANews | September 13, 2011
Every six years, asteroid 1999 RQ 36 nears Earth. Kicking off a global observation campaign, researchers are set to take advantage of the last asteroid fly-by before the launch of OSIRIS-REx, the first U.S.-led mission to bring back a sample of pristine asteroid material.

This Beetle Uses Eggs as Shields Against Wasps

UANews | September 13, 2011
Seed beetles often will stack their eggs, using them as shields to protect the bottom egg from attacks by parasitic wasps, reveals new research by doctoral candidate Joseph Deas in the UA's Graduate Interdisciplinary Program in Entomology and Insect Science.

When Plants Go Polyploid

UANews | September 12, 2011
Multiplying an entire genome – a naturally occurring process common in plants but less so in other organisms – comes with an evolutionary risk, researchers report in Science magazine. Plant lineages with multiple copies of their genetic information face higher extinction rates than their relatives whose genes were not duplicated.

UA Mining Lab Gets Jumbo Gift from Industry Partners

UANews | September 8, 2011
Mining engineers in the UA College of Engineering are the proud new owners of a 40-foot-long monster drilling rig, thanks to industry partners Asarco and Atlas Copco. Students will use the rig to carve out new tunnels at the UA's San Xavier Underground Mining Laboratory, about 23 miles south of Tucson.

Ancient Humans Were Mixing it Up

UANews | September 5, 2011
Anatomically modern humans interbred with more archaic hominin forms even before they migrated out of Africa, a UA-led team of researchers has found. The discovery suggests genetic exchange with their more morphologically diverged neighbors was more widespread than previously thought and all humans today may carry genes from now-extinct Homo varieties.
