Near-term applications could include remote detonation of land mines.
By zapping the air with a pair of powerful laser bursts, researchers at the University of Arizona have created highly focused pathways that can channel electricity through the atmosphere. (more…)
Antibiotic-resistant bacteria are an important concern for disease prevention in the future. UA doctoral candidate Victoria Obergh is testing Tucson-area wastewater systems to find out where these bacteria can be found.
Having a companion in old age is good for people — and, it turns out, might extend the chance for life on certain Earth-sized planets in the cosmos as well.
Planets cool as they age. Over time their molten cores solidify and inner heat-generating activity dwindles, becoming less able to keep the world habitable by regulating carbon dioxide to prevent runaway heating or cooling. (more…)
A UA-led study provides some of the first evidence for the hypothesis of co-divergence between parasites and hosts acting as a major driver of biodiversity.
Say what you will about the parasitic lifestyle, but in the game of evolution, it’s a winner. (more…)
UA researchers are working to ensure that firefighters and first responders breathe safely while cleaning up after fires.
Every year fires rage throughout the Southwestern U.S., placing firefighters and first responders at risk as they battle flames and smoke. University of Arizonaresearchersare working to make their jobs a bit safer by improving the breathing equipment they rely on to stay alive. (more…)
UA journalism student Amer Taleb has already had a stellar undergraduate career, working in newsrooms across the nation.
Amer Taleb‘s journalistic talent took him to Japan this summer, where he and other winners of the Roy W. Howard National Collegiate Reporting Competition toured multiple cities on a nine-day study trip. While in Hiroshima, he bought a silver keychain in the shape of a coin that was inscribed with a charge to work toward a more peaceful world. (more…)
Using bacteria as bait, UA scientists caught wild ocean viruses and found that the genetic lines between virus types in nature are less blurred than previously thought.
A fishing expedition of microscopic proportions led by University of Arizona ecologists revealed that the lines between virus types in nature are less blurred than previously thought. (more…)
New research by the University of Washington and the UA shows that background odors can interfere with pollinators’ ability to find flowers.
Car and truck exhaust fumes that foul the air for humans also cause problems for pollinators.
In new research on how pollinators find flowers when background odors are strong, University of Washington and University of Arizona researchers have found that both natural plant odors and human sources of pollution can conceal the scent of sought-after flowers. (more…)
