More on the ongoing debate of whether heredity or environment is in charge of who we are, from the assertive but knowledgeable English science writer Ridley.
Rather than just another exercise in stating the mutual dependence/interaction of genetic and environmental factors, the author provides examples of new-found genes that may turn on or off, may be more or less active, may or may not trigger a cascade of other gene actions, depending on circumstances. Nor is “the gene” always well-defined, he states. It can often be spliced in multiple ways, using alternative forms of component parts (the exons) with variable effects in various tissues. So, on the gene side, much variety, and on the nurture side, contexts galore, creating circles of complexity and feedback that render cause-effect statements (à la determinism) moot. Ridley’s examples and inferences include genes and their mutations in the course of evolution that influence brain size and neuronal connections, personality, sexuality, language, culture, aggression, and nurturance, but still operate as cogs in the wheel of experience. Ultimately, he declares in favor of free will. He avers that we must replace linear with circular causality, “in which an effect influences its own cause”—sounding just like a physicist talking about quantum mechanics. Before reaching that point, Ridley cites a dozen graybeards over the century who have kept the N/N debate alive, with some kind remarks for Boas and Durkheim, even Lorenz and Tinbergen, but excoriation for Freud, Skinner, and Watson. Trouble is, for all Ridley’s celebration of mutuality, some of the evidence he cites, such as twin studies, comes down strongly in terms of genes determining personality; while other data suggest that prenatal and infant experience (albeit via environmental influences on genes) are irrevocable.

A media-savvy scientist cleans out his desk.
Tyson (Astrophysics for People in a Hurry, 2017, etc.) receives a great deal of mail, and this slim volume collects his responses and other scraps of writing.
The prolific science commentator and bestselling author, an astrophysicist at the American Museum of Natural History, delivers few surprises and much admirable commentary. Readers may suspect that most of these letters date from the author’s earlier years when, a newly minted celebrity, he still thrilled that many of his audience were pouring out their hearts. Consequently, unlike more hardened colleagues, he sought to address their concerns. As years passed, suspecting that many had no interest in tapping his expertise or entering into an intelligent give and take, he undoubtedly made greater use of the waste basket. Tyson eschews pure fan letters, but many of these selections are full of compliments as a prelude to asking advice, pointing out mistakes, proclaiming opposing beliefs, or denouncing him. Readers will also encounter some earnest op-ed pieces and his eyewitness account of 9/11. “I consider myself emotionally strong,” he writes. “What I bore witness to, however, was especially upsetting, with indelible images of horror that will not soon leave my mind.” To crackpots, he gently repeats facts that almost everyone except crackpots accept. Those who have seen ghosts, dead relatives, and Bigfoot learn that eyewitness accounts are often unreliable. Tyson points out that extraordinary claims require extraordinary evidence, so confirmation that a light in the sky represents an alien spacecraft requires more than a photograph. Again and again he defends “science,” and his criteria—observation, repeatable experiments, honest discourse, peer review—are not controversial but will remain easy for zealots to dismiss. Among the instances of “hate mail” and “science deniers,” the author also discusses philosophy, parenting, and schooling.

Jahren transcends both memoir and science writing in this literary fusion of both genres.
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.
