Every day last week I attended the American Geophysical Union annual  meeting with a press pass. Along with some 25,000 researchers and others interested in research advances in the geological sciences, I attended short presentations about cutting edge research; poster sessions, where a scientist explains his or her work to individual listeners; and three press conferences or lectures on earth science-related subjects.
I learned as much as I could about three questions: What is underneath Yellowstone and how did it get there? What are microbiologists learning about the microbes that live in hot springs? How have humans been affecting the earth in the last century or so—and what should be done to reduce the damage?
It takes a while to digest all that, but in the next few weeks I will write blog posts and perhaps a new nugget about what I learned.
