THIS IS WHAT WE STUDY: A SAMPLING OF PROJECTS AND OUTREACH IN THE DEPARTMENT OF GEOLOGICAL SCIENCES
December 17, 2015 From the Toronto Star: Possibility of widespread ’deep-Earth life’ jolts scientists.
What if Earth hosts another ’biosphere’ of tiny microbial organisms deep below the surface?
"In a study published Wednesday in the journal Nature, research led by University of Toronto geoscientist Barbara Sherwood Lollar demonstrates that the environment that could host "deep-Earth life" is far vaster than previously imagined. And the possibility that we could find the same thing on other planets received an electric jolt Tuesday with the announcement that NASA’s Mars Curiosity rover had detected a plume of methane on the red planet that spiked and then dissipated – a potential signal of microbial life.
"It’s a critical reminder that the oceans and rivers and lakes on Earth give us a skewed view of the places where life could exist and evolve in another setting or another planet," said Lisa Pratt, a geochemist at Indiana University who was not involved in either paper. Pratt chairs the Mars Exploration Program Analysis Group, a community of scientists that advises NASA" .GO TO THE ARTICLE

Research links soil mineral surfaces to key atmospheric processes
From the IU Newsroom: Research by Indiana University scientists finds that soil may be a significant and underappreciated source of nitrous acid, a chemical that plays a pivotal role in atmospheric processes such as the formation of smog and determining the lifetime of greenhouse gases. The article, “Soil surface acidity plays a determining role in the atmospheric-terrestrial exchange of nitrous acid,” is being published this week by the journal Proceedings of the National Academy of Sciences and is available online. Melissa A. Donaldson, a Ph.D. student in the School of Public and Environmental Affairs, is the lead author. Co-authors are Raff and David L. Bish, the Haydn Murray Chair of Applied Clay Mineralogy in the Department of Geological Sciences.more
