Researchers have discovered four previously unknown viruses that infect the Earth's most abundant organism, the marine bacterium SAR11. Using data and methods developed by researchers with the UA's Tucson Marine Phage Research Lab, the analysis shows that, like their hosts, the new viruses are the most abundant on record. These tiny players have critical roles in the global cycle of carbon and other nutrients.
The UA and Pima County are entering the global water-energy sustainability arena by establishing the Water and Energy Sustainable Technology Laboratories at Pima County’s new Water Reclamation Campus. WEST Laboratories aspires to be a world-renowned venue for research and development of water treatment technologies, contaminant monitoring tools and energy minimization and production.
Plants can adapt their water use according to how much water is available, a team of scientists including UA rangeland ecologists reports in the journal Nature. However, this resilience has a limit, and in some of the world's more arid areas, including the American Southwest, prolonged drought conditions threaten the survival of these plant communities.
The Landscape Evolution Observatory inside the UA’s Biosphere 2 provides researchers with the first opportunity to study how water, microbes, soil and plants interact in a setting realistic enough to improve global climate models for years to come. The world's largest artificial watershed experienced its first - artificial - rain on Nov. 29 during LEO's formal commissioning.
Edited by UA faculty members, the soon-to-be published "Ground|Water: The Art, Design and Science of a Dry River" explores local water issues in a global context through the lens of the arts and humanities. Contributors include students and faculty members who submitted essays, poems, photographs, drawings and other works of art.
Shane Snyder, an environmental engineering professor, will meet this week with Korea's Minister of the Environment and give a presentation at an international water conference in Busan, Korea. The topic is emerging contaminants in drinking water and the different treatment levels required around the world to deliver safe water.
Southwestern droughts made more severe by warming temperatures are pushing plants up against extremely stressful growing conditions, a new study has found, identifying an increasingly water-thirsty atmosphere as a key force that sucks moisture from plants, drying out the region as temperatures rise in the wake of climate change.
A report by the UA’s Southwest Center outlines the poverty, water scarcity, food insecurity and interdependence found along the U.S. and Mexico border. The report has been released in advance of the Border Food Summit to be held in Rio Rico, Ariz. from Sept. 16-18.
Written by an expert cast of UA affiliates, "Last Water on the Devil's Highway: A Cultural and Natural History of Tinajas Altas" is perfect for desert aficionados and armchair explorers wishing to learn more about southwestern Arizona. The book was just published by the UA Press.
Mexico's Ciénega de Santa Clara has not changed since the 2010-11 pilot run of the Yuma Desalting Plant, according to a new report from a UA-led binational team of researchers. The 15,000-acre ciénega is the largest wetland in the Colorado River Delta.
