Arizona State University geophysicists detect a molten rock layer deep below the American Southwest

06-20-2007 · EurekAlert!

A sheet of molten rock roughly 10 miles thick spreads underneath much of the American Southwest, some 250 miles below Tucson, Ariz. From the surface, you can't see it, smell it or feel it. But Arizona geophysicists Daniel Toffelmier and James Tyburczy detected the molten layer with a comparatively new and overlooked technique for exploring the deep Earth that uses magnetic eruptions on the sun.

  1. Researchers detect hint of oxygen 50 to 100 million years earlier than first believed
    09-27-2007 · EurekAlert!
    Two multinational teams of scientists, including researchers from Arizona State University, are reporting that traces of oxygen appeared in Earth's atmosphere 50 to 100 million years before the "Great Oxidation Event." Analyzing layers of sedimentary rock in a core sample from the Hamersley Basin in Western Australia, the researchers report finding evidence that a small but significant amount of oxygen -- a whiff -- was present in the oceans and possibly Earth's atmosphere 2.5 billion years ago.

  2. New Analytical Tool Developed For Liquid Explosives Detection
    10-13-2006 · ScienceDaily
    The thwarted 2006 London airline bomb plot not only heightened summer travel fears and created new passenger screening inconveniences, but also greatly underscored the urgent need for improved national security measures. Now, professor Joe Wang, director of the Center for Biosensors and Bioelectronics at the Biodesign Institute at Arizona State University, has developed a highly sensitive technology to rapidly detect liquid peroxide explosives in as little as 15 seconds.

  3. Dig deeper to find Martian life
    01-30-2007 · EurekAlert!
    Probes designed to find life on Mars do not drill deep enough to find the living cells that scientists believe may exist well below the surface of Mars, according to research led by UCL (University College London). Although current drills may find essential tell-tale signs that life once existed on Mars, cellular life could not survive the radiation levels for long enough any closer to the surface of Mars than a few metres deep -- beyond the reach of even state-of-the-art drills.

  5. Computer program bridges gap between scientists, water policy makers
    02-17-2007 · EurekAlert!
    A computer visualization tool developed by Arizona State University researchers can simulate the effects environmental and policy factors have on the future of water availability in the Phoenix metropolitan area. The program, called WaterSim, will be demonstrated on February 17 by ASU geography professor Patricia Gober at the annual meeting of the American Association for the Advancement of Science in San Francisco.

  6. Nanotech's health, environmental impacts worry scientists and the public
    02-15-2008 · EurekAlert!
    Nanotechnology, which is making its way into products ranging from food storage containers to computers, is seen differently among scientists than the general public, with scientists appearing to be more concerned in some areas. This is among the findings of a recent survey that will be presented by Elizabeth Corley, an Arizona State University assistant professor, on Feb. 15 at the American Association for the Advancement of Science annual meeting.

  7. Helium isotopes point to new sources of geothermal energy
    11-29-2007 · EurekAlert!
    By measuring helium isotope ratios in fluids at the surface, geochemists Mack Kennedy of the Department of Energy's Lawrence Berkeley National Laboratory and Matthijs van Soest of Arizona State University have discovered a new tool for identifying potential geothermal energy resources. The potential resources arise not from volcanism but from the flow of surface fluids through deep fractures that penetrate the earth's lower crust, in regions far from current or recent volcanic activity.

  8. ASU researcher finds belief about neighbor's conservation is stealthily influential
    02-18-2007 · EurekAlert!
    If everyone jumped off a bridge, would you? Probably not, but according to a study by Arizona State University researchers, peer influence plays a greater role in people's behavior than is generally acknowledged. The study, which is being presented by ASU Regents' Professor of Psychology Robert Cialdini on Feb. 18 at the annual meeting of the American Association for the Advancement of Science, suggests that peer influence is an under-recognized factor in energy conservation.

  9. ASU researchers use NASA satellites to improve pollution modeling
    12-17-2007 · EurekAlert!
    Detecting pollution, like catching criminals, requires evidence and witnesses; but on the scale of countries, continents and oceans, having enough detectors is easier said than done. A team of air quality modelers, climatologists and air policy specialists at Arizona State University may soon change that. Under a grant from the Environmental Protection Agency, they have developed a new way to close the gaps in the global pollution dragnet by using NASA satellite data to detect precursors to ozone pollution.

  10. Hunting martian fossils best bet for locating Mars life, says ASU researcher
    02-16-2007 · EurekAlert!
    Hunting for traces of life on Mars calls for two radically different strategies, says Arizona State University professor Jack Farmer. Of the two, he says, with today's exploration technology we can most easily look for evidence for past life, preserved as fossil "biosignatures" in old rocks.Farmer is reporting on his work today (February 16) at the annual meeting of the American Association for the Advancement of Science in San Francisco.
