  • Volunteers needed to keep tabs on wind, rain
    Friday, April 13, 2012

    Wanted: citizens willing to keep a close watch on wild weather.

    "We have all this radar and other technology, but we're looking for eyes on the ground to verify that what we're looking at is actually happening," said Ken Drozd, warning coordination meteorologist with the National Weather Service.

    Volunteer weather spotters, Drozd said, "also can sometimes help us find out about something we might not be able to see very well with radar. They are a very...

  • Tsunami warnings lifted in panicked Indonesia
    Thursday, April 12, 2012

    BANDA ACEH, Indonesia - Cries of panic and fervent prayers rang out Wednesday as Indonesians rushed toward high ground after two strong earthquakes raised fears of a killer tsunami.

    Alerts were raised as far away as Africa and Australia, but this time the big waves didn't come.

    In western Indonesia, distraught women ran into the streets clinging to crying children as back-to-back tsunami warnings revived memories of the 2004 disaster that claimed 230,000 lives in nearly a...

  • Learn about Ironwood monument at all-day event
    Thursday, April 12, 2012

    Lahsha Brown likes to call the Ironwood Forest National Monument one of Arizona's best-kept secrets.

    "Even people who live in the area don't know about it," Brown said of the monument, which encompasses 129,000 acres - nearly 300 square miles - northwest of Saguaro National Park West.

    As executive director of the Friends of Ironwood Forest, Brown hopes to get the secret out this weekend as the nonprofit hosts its inaugural Meet the Monument event Saturday....

  • For UA Astronomy Students, the Sky is Not the Limit
    Thursday, April 12, 2012

    UA astronomy students Kevin Hardegree-Ullman and Jake Turner designed, proposed, conducted and presented research on two recently discovered planets outside of our solar system while they were still undergraduates.

    Deep in the cosmos, alien planets are circling distant stars, waiting to be pierced by the far-reaching gaze of Earth-bound telescopes. Some are Earth-like and have the potential to harbor liquid water and maybe even life. Others are enormous, gassy giants. All of them are...

  • Engineering Professor Wins Teaching, Research Awards
    Thursday, April 12, 2012

    Guzin Bayraksan has been honored with the 2012 Five Star Teaching Award and an NSF Faculty Early Career Development Program award that comes with $400,000 to research the sustainability of water in the Southwest.

    Assistant professor Guzin Bayraksan of the University of Arizona department of systems and industrial engineering has won the 2012 Five Star Teaching Award.

    Bayraksan was teaching...

  • Strong earthquake rattles Sonoran cities
    Thursday, April 12, 2012

    A strong earthquake this morning shook Sonora’s capital city and caused the evacuation of tourists from Kino Bay.

    The U.S. Geological Survey reported a 6.9 magnitude quake hit the Gulf of California waters between the Baja peninsula and Sonora about 12:15 a.m.

    That quake happened only hours after a separate temblor swayed tall buildings in Mexico City, causing evacuations. Authorities said neither quake left major damage nor victims.

    However, Sonoran officials...

  • Southwest in for an above average wildfire season
    Thursday, April 12, 2012

    TUCSON - After a record breaking wildfire season in 2011 it seems the southwest is heading for another active year.

    Every month the Southwest Coordination Center and National Interagency Fire Center issue a fire potential outlook. The forecast is aimed at warning the wildfire fighting community what precautions they need to take and where to allocate certain resources.

    For April a normal fire potential is forecast for the southwest portion of the United States. That includes...

  • H3+: The Molecule that Made the Universe
    Wednesday, April 11, 2012

    In a study that pushed quantum mechanical theory and research capabilities to the limit, UA researchers have found a way to see the molecule that likely made the universe - or at least the hot and fiery bits of it.

    Lurking in the vast, chilly regions between stars, the unassuming molecule known as a triatomic hydrogen ion, or H3+, may hold secrets of the formation of the first stars after the Big Bang.

    At the University of Arizona, then doctoral candidate Michele Pavanello...

  • Study blames ocean CO2 for oyster declines
    Wednesday, April 11, 2012

    Scientists are blaming slightly higher levels of carbon dioxide in Pacific Ocean waters linked to global warming for the failure of oyster larvae to survive in an Oregon hatchery.

    They say higher acidity of the water that comes with more carbon dioxide makes it harder for young oysters to form their shells, dooming them in a matter of days, even if they are moved to more favorable environments.

    "A lot of studies talk about the year 2050 when ocean acidification becomes a...

  • Flood danger following wildfires long-lasting
    Tuesday, April 10, 2012

    The flooding danger from wildfires lasts years and sometimes decades.

    Geologists and hydrologists who gathered at Biosphere 2 last week urged new strategies for anticipating damage from such floods, and better ways of measuring changes in watersheds and preparing strategies for lessening the danger downstream.

    Floods can be especially intense in watersheds fed by the steep slopes of Arizona's mountain ranges, which can often slough off the quick-fixes the post-fire crews...
