Who do we love? Who loves us? And why? Is love really a mystery, or can neuroscience offer some answers to these age-old questions?

In her third enthralling book about the brain, Judith Horstman takes us on a lively tour of our most important sex and love organ and the whole smorgasbord of our many kinds of love-from the bonding of parent and child to the passion of erotic love, the affectionate love of companionship, the role of animals in our lives, and the love of God.

Drawing on the latest neuroscience, she explores why and how we are born to love-how we're hardwired to crave the companionship of others, and how very badly things can go without love. Among the findings: parental love makes our brain bigger, sex and orgasm make it healthier, social isolation makes it miserable-and although the craving for romantic love can be described as an addiction, friendship may actually be the most important loving relationship of your life.

Based on recent studies and articles culled from the prestigious "Scientific American" and "Scientific American Mind" magazines, "The" Scientific American "Book of Love, Sex, and the Brain" offers a fascinating look at how the brain controls our loving relationships, most intimate moments, and our deep and basic need for connection.

From the Scopes "Monkey Trial" of 1925 to the court ruling against the Dover Area School Board's proposed intelligent design curriculum in 2005, few scientific topics have engendered as much controversy--or grabbed as many headlines--as evolution. And since the debate shows no signs of abating, there is perhaps no better time to step back and ask: What is evolution? Defined as the gradual process by which something changes into a different and usually more complex and efficient form, evolution explains the formation of the universe, the nature of viruses, and the emergence of humans. A first-rate summary of the actual science of evolution, this "Scientific American" reader is a timely collection that gives readers an opportunity to consider evolution's impact in various settings.
Divided into four sections that consider the evolution of the universe, cells, dinosaurs, and humans, "Evolution" brings together more than thirty articles written by some of the world's most respected evolutionary scientists. As tour guides through the genesis of the universe and complex cells, P. James E. Peebles examines the evidence in support of an expanding cosmos, while Christian de Duve discusses the birth of eukaryotes. In an article that anticipated his book "Full House, "Stephen Jay Gould argues that chance and contingency are as important as natural selection for evolutionary change. And Ian Tatersall makes two fascinating contributions, submitting his view that the schematic of human evolution looks less like a ladder and more like a bush.
With the latest on what's being researched at every level of evolutionary studies, from prospects of life on other planets to the inner working of cells,"Evolution" offers general readers an opportunity to update their knowledge on this hot topic while giving students an introduction to the problems and methodologies of an entire field of inquiry.

The international public health scare that resulted last year when a man infected with multidrug-resistant tuberculosis flew overseas from the United States and back illustrates both the fear and the potential impact of highly infectious diseases in a global age. At a time when scientists warn of the potential for an influenza epidemic to rival the deadly outbreak of 1919 and newspapers feature alarming headlines about incidences of mad cow disease, infectious disease will be a critical area of concern and scientific study in the twenty-first century. "Infectious Disease" collects thirty of the most exciting, innovative, and significant articles on communicable illness published in" "the pages of" Scientific" "American" magazine since 1993. With sections devoted to viral infections, infectious disease, the immune system, and global management and treatment issues, "Infectious Disease" provides general readers and students with an excellent overview of recent research in the field. Roger I. Glass discusses a potential vaccine for the rotavirus--a leading cause of severe childhood diarrhea world wide and frequent killer of young children in developing nations. Jeffery K. Taubenberger and colleagues investigate the virulent strain of influenza that killed up to 40 million people in 1919 to suggest treatments and recommend preventative measures. And Paul R. Epstein looks into whether global warming could be harmful to our health, untangling research that suggests that many diseases will flourish as Earth's atmosphere heats up. The prominence of disease in the ecology and evolution of human society has spurred investment in research and technology development, and, as a consequence, thetopic is much discussed in the general and scientific media. "Infectious Disease" is the essential sourcebook for anyone looking for the solid science and compelling narrative behind the stories that make headlines.
