Robert Lanza has been exploring the frontiers of science for more than four decades, and is considered one of the leading scientists in the world. He is Chief Scientific Officer at Advanced Cell Technology, and Adjunct Professor at Wake Forest University School of Medicine. He has several hundred publications and inventions, and 20 scientific books, among them, Principles of Tissue Engineering , which is recognized as the definitive reference in the field. Others include One World: The Health & Survival of the Human Species in the 21st Century (with a foreword by President Jimmy Carter), and the Handbook of Stem Cells and Essentials of Stem Cell Biology , which are considered the definitive references in stem cell research. Dr. Lanza received his B.A. and M.

D. degrees from the University of Pennsylvania, where he was both a University Scholar and Benjamin Franklin Scholar. He was also a Fulbright Scholar, and was part of the team that cloned the world's first human embryo, as well as the first to clone an endangered species, to demonstrate that nuclear transfer could reverse the aging process, and to generate stem cells using a method that does not require the destruction of human embryos. Dr. Lanza was awarded the 2005 Rave Award for Medicine by Wired magazine, and received the 2006 "All Star" Award for Biotechnology by Mass High Tech. Dr. Lanza and his research have been featured in almost every media outlet in the world, including all the major television networks, CNN, Time, Newsweek, People magazine, as well as the front pages of the New York Times, Wall Street Journal, Washington Post, Los Angeles Times, and USA Today , among others. Lanza has worked with some of the greatest thinkers of our time, including Nobel Laureates Gerald Edelman and Rodney Porter.

Lanza worked closely with B.F. Skinner at Harvard University. Lanza and Skinner (the "Father of Modern Behaviorism") published a number of scientific papers together. He has also worked with Jonas Salk (discoverer of the polio vaccine) and heart transplant pioneer Christiaan Barnard. Bob Berman is the world's most widely read astronomer. He has authored more than a thousand published articles in national magazines, written seven popular books for major publishers, and been a guest on such TV shows as TODAY , and Late Night with David Letterman . For the past decade he has been the chief astronomer for SLOOH, the community observatory.

Since 1989, Bob has been a popular monthly columnist in first Discover magazine (1989-2006), and then Astronomy magazine (1994 to present) where he's also the contributing editor. He is also the longtime astronomy editor of the Old Farmers Almanac . Listeners in seven states hear his Skywindow program on Northeast Public Radio stations during NPR's Weekend Edition. During the 1980s, Berman ran the summer astronomy program at Yellowstone Park for the National Park Service and Yellowstone Institute. Berman founded the Catskill Astronomical Society in 1976, the Storm King Observatory at Cornwall, New York, and Overlook Observatory, near Woodstock, New York. He was adjunct professor of astronomy and physics at Marymount College from 1995-2000. As a lecturer who leads large expeditions three times each year to celestial events such as auroras and total eclipses, as well as a SLOOH live commentator, Bob has spent five years overseas from the Arctic to the Antarctic, and has lectured for innumerable universities and federal entities, such as the National Institute for Standards and Technology.
