  • Water, climate change project gives new life to Biosphere 2
    Monday, December 3, 2012

    The massive greenhouse that once fed researchers who lived in the sealed-off world of Biosphere 2 is getting new life as a grand experiment to unlock the secrets of Earth’s water cycle.

    The University of Arizona last week commissioned the Landscape Evolution Observatory. The $7.5 million project under a half-acre of glass includes three identical “watersheds” sculpted from ground volcanic rock and loaded with thousands of subsurface sensors.

    Its builders...

  • New observatory at Biosphere 2 offers a look at life's 'thin veneer
    Monday, December 3, 2012

    The University of Arizona christened a novel earth-science experiment at Biosphere 2 last week with a gentle rain - a demonstration of how researchers will be able to vary climatic conditions on three massive indoor hillslopes loaded with sensors and samplers.

    On Friday, university researchers met with colleagues from other universities and representatives of federal funding agencies to discuss what to do with its new experimental instrument - and figure out how to sustain it.

    For the first time, overall enrollment at the University of Arizona this year has topped 40,000. Retention and graduation rates are up as well, as is the number of baccalaureate degrees conferred.

    Newly available enrollment statistics show that in 2012-13, 40,223 students enrolled at the UA, up from 39,236 last year. The UA has teetered near the 40,000 mark for the last few years.

    And in 2012, the one-year retention rate increased by 3 percent to 80.2 percent, up from 77.2...

  • Warm Arctic sets record for summer sea ice melt
    Tuesday, August 28, 2012

    Critical ice in the Arctic Ocean melted to record low levels this sweltering summer and that can make weather more extreme far away from the poles, scientists say.

    The National Snow and Ice Data Center reported Monday that the extent of Arctic sea ice shrank to 1.58 million square miles and is likely to melt more in the coming weeks. That breaks the old record of 1.61 million square miles set in 2007.

    The North Pole region is an ocean that mostly is crusted at the top with ice...

  • How The Smokey Bear Effect Led To Raging Wildfires
    Monday, August 27, 2012

    The history of fire in the American Southwest is buried in a catacomb of rooms under the bleachers of the football stadium at the University of Arizona.

    Here rules professor Thomas Swetnam, tree ring expert. You want to read a tree ring? You go to Tom. He's a big, burly guy with a beard and a true love for trees.

    Tree sections are stacked floor to ceiling. They're like rounds chopped from a carrot, the carrot being a tree trunk. They're the size of dinner plates....

  • The UA's Land-Grant Mission: Its Contemporary Relevance
    Monday, August 27, 2012

    The often-evoked land-grant mission represents the foundational basis for the University of Arizona's bond with Arizona communities along with its efforts to expand educational opportunities while helping to address important societal concerns.

    But the mission – a 150-year-old charge enacted with the passage of the Morrill Land-Grant Act of 1862 – was drafted during a time of widely different social contexts, financial and intellectual resources and national priorities...

  • What UA Deans Say About the Land-Grant Mission
    Monday, August 27, 2012

    As part of a week-long package on the history and contemporary relevance of the UA's land-grant mission, University deans were asked to talk about what the mission means to their respective colleges. Here are some of their responses:

    Acknowledging the Mission's Expansive Meaning

    "While land-grant universities certainly originated with the idea of teaching practical agriculture and engineering skills, I think the mission has evolved to mean...
