In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard’s top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization.   In Extraterrestrial, Loeb takes readers inside the thrilling story of the first interstellar visitor to be spotted in our solar system. He outlines his controversial theory and its profound implications: for science, for religion, and for the future of our species and our planet. A mind-bending journey through the furthest reaches of science, space-time, and the human imagination, Extraterrestrial challenges readers to aim for the stars—and to think critically about what’s out there, no matter how strange it seems.

    The DOs chronicles the development of this controversial medical movement from the nineteenth century to the present. Historian Norman Gevitz describes the philosophy and practice of osteopathy, as well as its impact on medical care. From the theories underlying the use of spinal manipulation developed by osteopathy's founder, Andrew Taylor Still, Gevitz traces the movement's early success, despite attacks from the orthodox medical community, and details the internal struggles to broaden osteopathy's scope to include the full range of pharmaceuticals and surgery. He also recounts the efforts of osteopathic colleges to achieve parity with institutions granting M.D. degrees and looks at the continuing effort by osteopathic physicians and surgeons to achieve greater recognition and visibility.In print continuously since 1982, The DOs has now been thoroughly updated and expanded to include two new chapters addressing recent and current challenges and to bring the history of the profession up to the beginning of the new millennium.

    In First Light, he demonstrates his gift for creating an exciting and absorbing narrative around a complex scientific subject--in this case the efforts by astronomers at the Palomar Observatory in the San Gabriel Mountains of California to peer to the farthest edges of space through the Hale Telescope, attempting to solve the riddle of the creation of the universe. Richard Preston's name became a household word with The Hot Zone, which sold nearly 800,000 copies in hardcover, was on The New York Times's bestseller list for 42 weeks, and was the subject of countless magazine and newspaper articles. Preston has become a sought-after commentator on popular science subjects. For this hardcover reprint of what has been called "the best popular account of astronomy in action," (Kirkus Reviews) he has revised the text and written a new introduction.
