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.

A Peabody Award–winning NPR science reporter chronicles the life of a turn-of-the-century scientist and how her quest led to significant revelations about the meaning of order, chaos, and her own existence.
Miller began doing research on David Starr Jordan (1851-1931) to understand how he had managed to carry on after the 1906 San Francisco earthquake destroyed his work. A taxonomist who is credited with discovering “a full fifth of fish known to man in his day,” Jordan had amassed an unparalleled collection of ichthyological specimens. Gathering up all the fish he could save, Jordan sewed the nameplates that had been on the destroyed jars directly onto the fish. His perseverance intrigued the author, who also discusses the struggles she underwent after her affair with a woman ended a heterosexual relationship. Born into an upstate New York farm family, Jordan attended Cornell and then became an itinerant scholar and field researcher until he landed at Indiana University, where his first ichthyological collection was destroyed by lightning. In between this catastrophe and others involving family members’ deaths, he reconstructed his collection. Later, he was appointed as the founding president of Stanford, where he evolved into a Machiavellian figure who trampled on colleagues and sang the praises of eugenics. Miller concludes that Jordan displayed the characteristics of someone who relied on “positive illusions” to rebound from disaster and that his stand on eugenics came from a belief in “a divine hierarchy from bacteria to humans that point[ed]…toward better.” Considering recent research that negates biological hierarchies, the author then suggests that Jordan’s beloved taxonomic category—fish—does not exist. Part biography, part science report, and part meditation on how the chaos that caused Miller’s existential misery could also bring self-acceptance and a loving wife, this unique book is an ingenious celebration of diversity and the mysterious order that underlies all existence.

Award-winning scientist Jahren (Geology and Geophysics/Univ. of Hawaii) delivers a personal memoir and a paean to the natural world.
The author’s father was a physics and earth science teacher who encouraged her play in the laboratory, and her mother was a student of English literature who nurtured her love of reading. Both of these early influences engrossingly combine in this adroit story of a dedication to science. Jahren’s journey from struggling student to struggling scientist has the narrative tension of a novel and characters she imbues with real depth. The heroes in this tale are the plants that the author studies, and throughout, she employs her facility with words to engage her readers. We learn much along the way—e.g., how the willow tree clones itself, the courage of a seed’s first root, the symbiotic relationship between trees and fungi, and the airborne signals used by trees in their ongoing war against insects. Trees are of key interest to Jahren, and at times she waxes poetic: “Each beginning is the end of a waiting. We are each given exactly one chance to be. Each of us is both impossible and inevitable. Every replete tree was first a seed that waited.” The author draws many parallels between her subjects and herself. This is her story, after all, and we are engaged beyond expectation as she relates her struggle in building and running laboratory after laboratory at the universities that have employed her. Present throughout is her lab partner, a disaffected genius named Bill, whom she recruited when she was a graduate student at Berkeley and with whom she’s worked ever since. The author’s tenacity, hope, and gratitude are all evident as she and Bill chase the sweetness of discovery in the face of the harsh economic realities of the research scientist.
