  • NAI-WARC Highlight: The Biology Behind Banded Iron Formations
    A long-enduring puzzle in the evolution of the early Earth concerns when and to what extent surface oxidation occurred. One important piece of this puzzle is determining when oxygen production began, and how early oxygen was consumed by reduced species, such as iron (Fe(II)), in the oceans. More information can be found here.

  • In Memoriam: Dr. Baruch S. “Barry” Blumberg 1925 – 2011
    Nobel Laureate Baruch S. Blumberg died of an apparent heart attack on April 5, while attending a conference at NASA Ames Research Center. He was 85. Known to friends and colleagues as Barry, Dr. Blumberg served as the first director of the NASA Astrobiology Institute (1999-2002) and an advocate for astrobiology ever since. At the time of his death, he was Distinguished Scientist at the both the NASA Astrobiology Institute and the NASA Lunar Science Institute. More information can be found here.

  • NASA Selects New Science Teams for Astrobiology Institute
    The NASA Astrobiology Institute (NAI) has awarded a new round of five-year grants, averaging $7 million each, to 10 research teams from across the country to study the origins, evolution, distribution, and future of life in the universe. These ten teams, part of the fifth cycle of NAI awards (“CAN-5”) are in addition to four continuing (“CAN-4”) teams that include our Wisconsin-based WARC team, as well as those at MIT, University of Washington, and Montana State, bringing the total number of NAI teams to 14. The 10 new teams are based at NASA’s Ames Research Center, NASA’s Jet Propulsion Lab (2 teams), NASA’s Goddard Space Flight Center, the University of Hawaii, Arizona State University, the Carnegie Institution of Washington, Pennsylvania State University, Georgia Tech, and Rensselaer Polytechnic Institute. Details may be found here.
