In Science, scientists at Washington University in St. Louis report on a new technique that allowed them to extract a photosynthetic megacomplex consisting of a light antenna and two reaction centers from the membrane of a cyanobacterium. This is the first time an entire complex has been isolated and studied as a functioning whole.

Political scientist William Lowry has paid close attention to environmental issues for 25 years, marshaling what he learns each year and testing it in front of a class of critical students. He has honed his class “Environmental and Energy Issues” to the point where it is a white-water ride down a river of arguments and counterarguments that puts everything in context and lays out the facts — but skips the lecturing and fearmongering that characterize this debate. There can be no better guide to the perplexed.

Two faculty members from Washington University in St. Louis have been named fellows of the American Association for the Advancement of Science, the world’s largest general scientific society. They are Michael J. Holtzman, MD (left), and Rohit V. Pappu, PhD.

Our sense of smell is often the first response to environmental stimuli. Odors trigger neurons in the brain that alert us to take action. However, there is often more than one odor in the environment, such as in coffee shops or grocery stores. How does our brain process multiple odors received simultaneously? Barani Raman, PhD, of the School of Engineering & Applied Science, is using locusts to help find the answer.

Visiting scientist Stephen Blake has traveled the world trying to protect endangered species, including forest elephants and giant tortoises. Lately he and his wife veterinarian Sharon Deem have put increasing emphasis on trying to restore another endangered species: kids who care about nature. They’ve started the St. Louis Box Turtle Project as a kid-friendly way to re-introduce kids to the woods.

Himadri Pakrasi, PhD, director of the International Center for Advanced Renewable Energy and Sustainability, sat down recently with Peter Raven, PhD, the George Engelmann Professor of Botany Emeritus in Arts & Sciences and president emeritus of the Missouri Botanical Garden, for a conversation about the Washington University Climate Change Initiative.

A temporary seismic array in Marie Byrd Land in West Antarctica recorded two bursts of activity in 2010 and 2011. Careful analysis of the events shows they originate from a subglacial volcano at the leading end of a volcanic mountain chain. The volcano is unlikely to erupt through the kilometer of ice that covers it but it will melt enough ice to change the way the ice in its vicinity flows.

Washington University in St. Louis’ Olin Business School and School of Engineering & Applied Science have announced a partnership with the startup-focused news organization Techli to promote the growing entrepreneurship community in and around St. Louis.

Washington University, recognized for its leadership in the Sustainable Land Lab, a partnership with the City of St. Louis, and for furthering sustainability efforts on campus, was one of six entities to receive a sustainability award from the City of St. Louis Nov. 6 during the Mayor’s Sustainability Summit.

Washington University has received a $1.8 million grant from the National Institutes of Health (NIH) to foster student diversity in its PhD training program in the biomedical sciences. Pictured are inaugural scholars from the program.
