An instrument designed and built at the UofA measured the isotopic composition of the Mars atmosphere, suggesting liquid water has interacted with the Martian surface throughout the planet's history.



Findings, published today in the Sept. 10 issue of the journal "Science", suggest a rare but existant lifecycle of liquid water interacted with the surface over time. Furthermore, that water may have existed at temperatures near freezing; implying hydrothermal systems liken to Yellowstone National Park. An instrument designed and built at the UA measured the isotopic composition of the Mars atmosphere, providing providing much anticipated data on how liqid once acted with the Martian surface throughout the planet's history.

Biospere 2 Hosts 2010 Scialog Interation Week

The general public is invited to attend two keynote speeches with leading scientists in addition to the event, both of which will take place in Tucson at the University of Arizona: Eric Mazur; will speak at 5:30 pm on Thursday, October 14 at the University of Arizona. Dr. Mazur is a world-renowned authority on ultrashort laser pulse interactions and novel nonlinear optical devices, and a widely recognized leader in science education. He will speak on "The Make-Believe World of Real-World Physics."

Arun Majumdar will speak on 'Energy Issues Facing the U.S.' at 7:00 pm on Friday, October 15. Dr. Majumdar previously served as Associate Laboratory Director for Energy and Environment at Lawrence Berkeley National Laboratory and Professor of Mechanical Engineering and Materials Science and Engineering at the University of California, Berkeley. His research specialties include the science and engineering of energy conversion, transport, and storage.

Scialog Week is an extraordinary opportunity for interaction around advanced scientific inquiry being hosted by Biosphere 2 in Oracle, Arizona. "Scialog®" - coined by About Research Corporation for Science Advancement OCTOBER 12 TO 15 at Biosphere 2 In Oracle, AZ.

Featured scientists, including the following: Roger Angel, 2010 Kavli Prize-winner in astrophysics and Regents' Professor at the University of Arizona; Nathan Lewis, the George L. Argyros Professor of Chemistry at Caltech, Director of the U.S. Department of Energy's Energy Innovation Hub, and chair of the panel of internationally recognized scientists who selected the initial Scialog grantees; Eric Mazur, Balkanski Professor of Physics and Applied Physics at Harvard University; Arun Majumdar, Director of ARPA-E, the U.S. government agency created to promote and fund research and development of advanced energy technologies; Thomas Moore, Professor of Chemistry at Arizona State University and Director of its Center for Bioenergy & Photosynthesis.
