Aerospace consultant Nick Cook, author of the new book, The Hunt for Zero Point: Inside the Classified World of Antigravity Technology. (Broadway Books/ Random House) In the book, Cook tracks down the secret history of anti-gravity research. It*s technology that defies the laws of physics. Cook discovered that during WWII, the Nazis claimed to have been close to antigravity technology. The U.S. government allegedly conducted antigravity research in the 1950s and 60s. Cook is former Aviation Editor for the military affairs journal, Jane's Defense Weekly.

Brazilian physicist Marcelo Gleiser is the author of the new book, The Prophet and the Astronomer: A Scientific Journey to the End of Time (WW Norton). In it he explores our relationship to the sky and how it has influenced religion and then in turn - science. He writes, 'one of my goals. . is to humanize science, to argue that our scientific ideas are very much a product of the cultural and emotional environment where they originate'. Gleiser is Professor of Natural Philosophy and professor of physics and astronomy at Dartmouth College.

Journalist Jon Cohen writes for Science Magazine. He just got back from the 14th International AIDS conference where he reported on the AIDS vaccine and anti-HIV drug therapies. His article "Designer Bugs" in the July/August edition of The Atlantic Monthly is about how scientists have the ability to create synthetic viruses in the lab, like mousepox and polio, and the controversies and dangers this presents.

Columnist Robert Wolke writes Food 101 for The Washington Post, a syndicated column that won the James Beard Foundation Award for best newspaper column. He's the author of the new book What Einstein Told His Cook: Kitchen Science Explained. Wolke is also professor emeritus of chemistry at the University of Pittsburgh.

We remember paleontologist and evolutionary biologist Stephen Jay Gould. He died Monday at the age of 60. Gould was a professor of geology at Harvard and curator of the university's Museum of Comparative Zoology. He wrote columns for Natural History Magazine and Discover Magazine, and had written several books, including the award-winning The Mismeasure of Man. Gould used his writing and teaching to demystify the scientific method and to provide a historical perspective on science for the layman.

Science and natural history writer Hannah Holmes. Her new book is The Secret Life of Dust: From the Cosmos to the Kitchen Counter, the Big Consequences of Little Things. (John Wiley & Sons) Among the interesting facts youl find in the book is this: within a juice glass sitting in the sun, you would find 25,000 microscopic pieces of dust, at a minimum.

Volcanologist and resident geologist for the U.S. Geological Survey Dan Miller. He also heads the Survey’s Volcano Disaster Assistance program which helps developing countries in the event of volcanic eruption. Miller was part of the team of geologists who studied Mt. St. Helens and predicted a blast before the turn of this last century. Mt. St. Helens blew May 18th, 1980. His team studied the frequency and past characteristics of eruption in Mt. St. Helens and put together hazard assessments for local officials.

Doctor Mel Greaves, author of Cancer: The Evolutionary Legacy (Oxford University Press. Greaves is professor of cell biology and director of the Leukemia Research Fund Centre for Cell and Molecular Biology at the Institute of Cancer Research in London. Greaves places cancer in its evolutionary context, using examples from the 15th century to the most contemporary research. Greaves talks about the importance of looking at cancer through a Darwinian lens. He says there may be implications for research, prevention, and treatment.
