by William R. Clark ‧ RELEASE DATE: April 1, 1999
A virtual textbook on what the growing knowledge of biochemistry, genetics, and molecular biology is revealing about the basic mechanisms of aging. Clark, professor emeritus of immunology at Univ. of Calif., Los Angeles, whose previous work, The New Healers: Molecular Medicine in the Twenty-First Century (1997), seriously challenged readers not trained in these sciences, has returned to the classroom for yet another dense lecture, complete with graphs, tables, and diagrams. With technical expertise, he describes in detail how the process of aging, or senescence, takes place at the level of individual cells and what is known about the internal regulation of that process by our genes. He relates how research into various genetic disorders that mimic the human aging process, such as Hutchinson-Gilford progeria and Werner’s syndrome, is providing clues to the involvement of genes in the aging process; and he dismisses claims that rejuvenation or immortality can be achieved through the manipulation of telomeres, those segments of DNA at the tip ends of chromosomes that have been called the cell’s internal timekeepers. The effects of caloric restriction on lifespan are considered, as is the role of antioxidants in reducing the risk of deadly cancers and cardiovascular disease. What is clear from Clark’s text is that more is known about how and why we age than has ever been known before, and that with the coming completion of the Human Genome Project, knowledge of the genes involved in aging will greatly expand. In his final chapter, which is the book’s least technical and most thought-provoking, Clark considers briefly what the impact on society will be as that knowledge is applied and leads to a longer, healthier average human lifespan. A scientist’s careful, unsensational account of the current status of research into aging that requires from the reader a level of commitment well beyond mere curiosity.

Italian theoretical physicist Rovelli (General Relativity: The Most Beautiful of Theories, 2015, etc.) shares his thoughts on the broader scientific and philosophical implications of the great revolution that has taken place over the past century.
These seven lessons, which first appeared as articles in the Sunday supplement of the Italian newspaper Sole 24 Ore, are addressed to readers with little knowledge of physics. In less than 100 pages, the author, who teaches physics in both France and the United States, cogently covers the great accomplishments of the past and the open questions still baffling physicists today. In the first lesson, he focuses on Einstein's theory of general relativity. He describes Einstein's recognition that gravity "is not diffused through space [but] is that space itself" as "a stroke of pure genius." In the second lesson, Rovelli deals with the puzzling features of quantum physics that challenge our picture of reality. In the remaining sections, the author introduces the constant fluctuations of atoms, the granular nature of space, and more. "It is hardly surprising that there are more things in heaven and earth, dear reader, than have been dreamed of in our philosophy—or in our physics,” he writes. Rovelli also discusses the issues raised in loop quantum gravity, a theory that he co-developed. These issues lead to his extraordinary claim that the passage of time is not fundamental but rather derived from the granular nature of space. The author suggests that there have been two separate pathways throughout human history: mythology and the accumulation of knowledge through observation. He believes that scientists today share the same curiosity about nature exhibited by early man.
An intriguing meditation on the nature of the universe and our attempts to understand it that should appeal to both scientists and general readers.Pub Date: March 1, 2016

by Richard Rhodes ‧ RELEASE DATE: Feb. 1, 1986
A magnificent account of a central reality of our times, incorporating deep scientific expertise, broad political and social knowledge, and ethical insight, and Idled with beautifully written biographical sketches of the men and women who created nuclear physics. Rhodes describes in detail the great scientific achievements that led up to the invention of the atomic bomb. Everything of importance is examined, from the discovery of the atomic nucleus and of nuclear fission to the emergence of quantum physics, the invention of the mass-spectroscope and of the cyclotron, the creation of such man-made elements as plutonium and tritium, and implementation of the nuclear chain reaction in uranium. Even more important, Rhodes shows how these achievements were thrust into the arms of the state, which culminated in the unfolding of the nuclear arms race. Often brilliantly, he records the rise of fascism and of anti-Semitism, and the intensification of nationalist ambitions. He traces the outbreak of WW II, which provoked a hysterical rivalry among nations to devise the bomb. This book contains a grim description of Japanese resistance, and of the horrible psychological numbing that caused an unparalleled tolerance for human suffering and destruction. Rhodes depicts the Faustian scale of the Manhattan Project. His account of the dropping of the bomb itself, and of the awful firebombing that prepared its way, is unforgettable. Although Rhodes' gallery of names and events is sometimes dizzying, his scientific discussions often daunting, he has written a book of great drama and sweep. A superb accomplishment.
