Laser ‘Lightning Rods’ Channel Electricity through Thin Air

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…)

Testing Water for Antibiotic-Resistant Bacteria

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.

In the lab, Victoria Obergh transfers bacterial DNA samples into a tray. A graduate student in the University of Arizona’s Department of Soil, Water and Environmental Science, part of the College of Agriculture and Life Sciences, Obergh works with the samples under a sterile hood sporting an ultraviolet light to kill any unwanted DNA.

Companion planets can increase old worlds’ chance at life

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…)

Galápagos Hawks Hand Down Lice Like Family Heirlooms, Study Finds

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…)

Tiniest Catch: UA Scientists’ Fishing Expedition Reveals Viral Diversity in the Sea

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…)

Fumes Keep Moths from Finding Flowers, Study Discovers

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…)
