An entertaining overview of the science of physical attraction.
A pop-science analysis of the complex brain chemicals behind lust and love.
Why do we drunk-dial our exes? Why do strippers make more money when they are ovulating? Why do fools fall in love? These are some of the questions explored by Young (Psychiatry/Emory Univ.) and journalist Alexander (America Unzipped: In Search of Sex and Satisfaction, 2008). The authors argue that the causes are related to the potent, sometimes irresistible, chemical cocktails our bodies produce. In interviews with scientists of all stripes (psychiatrists, neuroscientists, researchers), Young and Alexander examine their ideas and how they pertain to us, often illuminating their explanations with funny, and sometimes raunchy, anecdotes. One researcher studying leeches described the male leech as “the icky guy in the bar hitting on every female,” while a neuroscientist studying the links between smell and sex in rats joked that a female rat became “the major party girl” during an experiment. Some animal lovers may be disturbed by the occasionally flippant tone describing some gruesome lab experiments—e.g., “it turned out shooting electricity into cat brains just gets you angry cats.” The authors’ analysis of the differences between male and female brains suffers from this glib attitude as well, but the book is sure to hook even casual science readers with its subject, because, as Young and Alexander point out, “the combination of erotic desire and the love it leads to may be the most powerful force on earth.”

An informal, first-person account of the discovery of a genetic link to male homosexuality by a scientist who has given thought to the ramifications of his findings. With the help of Scripps-Howard journalist Copeland, Hamer, a molecular geneticist who heads the National Cancer Institute's section on gene structure and regulation, describes in just the right amount of detail how he put together his research project on homosexuality. He relates how he obtained approval, funding, a research team, and a place to work; how he found the volunteers he needed (gay brothers willing to give blood samples and answer a lot of very personal questions); and what he learned from them and their family trees. Genetics being a statistical science, there's a fair amount of discussion of statistical techniques, but happily this is mostly presented with the general reader in mind. Hamer's account offers a glimpse into both the collegiality and the politics of science, and there's a delightful chapter on a confrontation he had at Harvard with critics of his research. The final portion of his book presents theories about how genes may influence sexual behavior and other human attributes and speculation about the implication of his research. In July 1993, in the midst of intense public debate over gays in the military, the journal Science published Hamer's paper, ``A Linkage Between DNA Markers on the X Chromosome and Male Sexual Orientation.'' Tabloids and TV talk shows took it from there. Hamer does not dwell on his time in the spotlight, but the experience evidently sharpened his awareness of public concerns and misconceptions. After noting the possible misuses of genetic research, Hamer concludes that the real danger lies in not studying sex at all. Appendixes include the Science article (not seen) and the interview questionnaire used with research participants. Nothing to titillate, but plenty to think about.

Leading neuroscientist Montague takes a biomechanical approach to explain the mental processes that occur in decision-making.
Like computers, the human brain processes data and produces a result—but with a twist, declares the author. The gray area of computational neuroscience lies in the value judgments that occur in biological systems. Nature, Montague posits in his debut, has equipped the biological machine with the added ability to determine the significance of a computation. Moreover, by storing these valuations as a byproduct of computation, the mind adapts and becomes increasingly more efficient. Repeated exposure to a typical risk-reward scenario, for example, causes the mind to anticipate outcomes. Montague revisits many of the old “right-brain” scenarios with a “left-brain” approach. With a graduate student, he replicated the famous “Pepsi Challenge” and found no relationship between the drink selected in the test and the drinks that subjects actually purchased in the stores. Though Montague’s research is thorough, his explanations vary from wry to impenetrably abstract, and the definition of value remains elusive. Value may be a burst of dopamine, a goal created from a pattern of inputs from the environment, an abstract emotion such as trust, or anything in-between. The essence of Montague’s work is that biological machines assign a value “tag” to each piece of data that they process. Whether tiny bacteria or human being, this is what differentiates us from the machines we create. The “soul” of the human machine may be the sum of these value tags. The answer to the titular question is itself a value judgment based on individual experience.
