Health and Science writer Carl Zimmer's new book is Soul Made Flesh: The Discovery of the Brain-and How it Changed the World. It's about Thomas Willis, the scientist whose research on the workings of the brain during the 17th century became the basis of modern neurology. Zimmer's work appears regularly in The New York Times, National Geographic, Newsweek, Discover, Natural History, and Science. He is also a John S. Guggenheim Fellow and received the Pan-American Health Organization Award for Excellence in International Health Reporting.

Artist and photographer Joseph Scheer is a professor of print media and co-director of the Institute of Electronic Art at Alfred University in New York. Over the last few years he's collected more than 20,000 specimen of moths. He then photographed them up close, capturing the varied colors and patterns not visible to the naked eye. He's collected them in the new over-sized book, Night Visions: The Secret Designs of Moths. It includes an introduction by Marc Epstein, a Lepidopterist (moth expert) at the National Museum of Natural History of the Smithsonian Institute.

He is the editorial page editor of The Rutland Herald in Vermont, where he won that paper's first Pulitzer for his series of editorials in support of same-sex unions. He's the author of the new book, Civil Wars: A Battle for Gay Marriage. Vermont became the first state in the country to make civil unions legal for gay and lesbian couples. In 1999, the state Supreme Court ruled that gay couples were due the legal rights of marriage, and told the state legislature to decide how best to do that.
