Washington, DC—Human industry and ingenuity has done more to diversify and distribute minerals on Earth than any development since the rise of oxygen over 2.2 billion years ago, experts say in a paper published today. The work bolsters the scientific argument to officially designate a new geological time interval distinguished by the pervasive impact of human activities: the Anthropocene Epoch.

Bob Hazen, staff scientsist at the Geophysical Laboratory, continues our Neighborhood Lecture Series with the second of four lectures. The distribution of minerals on Earth, Mars, and other worlds mimics social networks, as commonly applied to such varied topics as Facebook interactions, the spread of disease, and terrorism networks.
The Geophysical Laboratory's weekly seminar series continues with Eli Moore from the Department of Marine and Coastal Sciences at Rutgers. He will present, "Global Redox Influence on Metal Availability, the Evolution of Archean Metabolisms, and the Search for Ancient Proteins."

Zhixue Du joins the Geophysical Laboratory as a Carnegie Fellow from Yale University, where he just received his Ph.D. in Geophysics. He is working with Yingwei Fei and the rest of the staff on various projects and is very interested in mineral physics.
Washington, DC— A team of scientists including Carnegie’s Dina Bower and Andrew Steele weigh in on whether microstructures found in 3.46 billion-year-old samples of a silica-rich rock called chert found in Western Australia are the planet’s oldest fossils.
