A "skillful and literate" ( New York Times Book Review ) biography of the persecuted genius who helped create the modern computer. To solve one of the great mathematical problems of his day, Alan Turing proposed an imaginary computer. Then, attempting to break a Nazi code during World War II, he successfully designed and built one, thus ensuring the Allied victory. Turing became a champion of artificial intelligence, but his work was cut short. As an openly gay man at a time when homosexuality was illegal in England, he was convicted and forced to undergo a humiliating "treatment" that may have led to his suicide. With a novelist's sensitivity, David Leavitt portrays Turing in all his humanity?his eccentricities, his brilliance, his fatal candor?and elegantly explains his work and its implications.

In Menachem's Seed , Carl Djerassi , world-renowned scientist and inventor of the birth-control pill, brings us a new novel that explores the human--and passionate--side of science. Melanie Laidlaw and Menachem Dvir meet at a series of international conferences where jet-setting scientists come together to discuss the global implications of their discoveries. Melanie runs a foundation that awards grants for innovations in reproductive technology; Menachem is an infertile nuclear engineer and a married man. Naturally, they fall in love. What follows is a story of sexual steam, stolen seed, and religious conversion--a very modern romance that hinges on a cutting-edge scientific breakthrough. As Melanie and Menachem discover, what science makes possible, only two hearts can make right.

A new fertility drug is developed in Israel with the help of the heroine, Renu Krishnan, a postgraduate student from India. She personally assists the inventor in his erection tests and becomes involved in the marketing of the drug. A look at the way new drugs are developed.

What are the conditions that foster true novelty and allow visionaries to set their eyes on unknown horizons? What have been the challenges that have spawned new innovations, and how have they shaped modern biology? In Dreamers, Visionaries, and Revolutionaries in the Life Sciences , editors Oren Harman and Michael R. Dietrich explore these questions through the lives of eighteen exemplary biologists who had grand and often radical ideas that went far beyond the run-of-the-mill science of their peers. From the Frenchman Jean-Baptiste Lamarck, who coined the word “biology” in the early nineteenth century, to the American James Lovelock, for whom the Earth is a living, breathing organism, these dreamers innovated in ways that forced their contemporaries to reexamine comfortable truths. With this collection readers will follow Jane Goodall into the hidden world of apes in African jungles and Francis Crick as he attacks the problem of consciousness. Join Mary Lasker on her campaign to conquer cancer and follow geneticist George Church as he dreams of bringing back woolly mammoths and Neanderthals. In these lives and the many others featured in these pages, we discover visions that were sometimes fantastical, quixotic, and even threatening and destabilizing, but always a challenge to the status quo.

"When it comes to the phenomenon that is consciousness, there is one point on which scientists, philosophers, and artists all agree: that it feels like something to be us. Yet the fact we have subjective experience of the world remains one of nature's greatest mysteries. How is it that our mental operations are accompanied by feelings, thoughts, and a sense of self? What would a scientific investigation of our inner life look like, considering we have as little distance and perspective on it as fish do of the sea? In A World Appears, Michael Pollan traces the unmapped continent that is consciousness, bringing radically different perspectives-scientific, philosophical, literary, spiritual and psychedelic-to see what each can teach us about this central fact of life. When neuroscientists began studying consciousness in the early 1990s, they sought to explain how and why three pounds of spongy grey matter could generate a subjective point of view-assuming that the brain is the source of our felt reality. Pollan takes us to the cutting edge of the field, where scientists are entertaining more radical (and less materialist) theories of consciousness. He introduces us to "plant neurobiologists" searching for the first flicker of consciousness in plants; scientists striving to engineer feelings into AI, and psychologists and novelists seeking to capture the felt experience of our slippery stream of consciousness. In Pollan's dazzling exploration of consciousness, he discovers a world far deeper and stranger than our everyday reality. Eye-opening and mind-expanding, A World Appears takes us into the laboratories of our own minds, ultimately showing us how we might make better use of the gift of awareness to more meaningfully connect with our deepest selves"-- Provided by publisher.

This novel, like Jurassic Park , hinges on the real-world technology incorporated in the polymerase chain reaction (PCR), one of the most important breakthroughs in biomedical science. The 1993 Nobel Prize in chemistry recognized the immense significance of PCR, which is a process for quickly generating and then infinitely replicating fragments of genetic material. An impostor takes all of the credit in Carl Djerassi's fictionalized account of PCR's discovery and development. As the scientific community eventually discovers, Professor Diana Skordylis is not really one of their own, she is four of their own--three men and a woman--who publish their collaborative work under the Skordylis pseudonym. Two of them American, one Japanese, and one Austrian, they average around sixty-five years of age. Their archetype is a famous group of French mathematicians who actually have been publishing collectively for several decades under the nom de plume of Nicolas Bourbaki. Revenge is the Skordylis group's initial motivation. Victims of subtle age discrimination, they have all seen their research budgets and faculty privileges curtailed; two have been forcibly retired. Each Skordylis project they complete, each paper they publish under her name, is a satisfying poke at a scientific community that marginalized its senior members. But PCR is different. It is not only their best work, it is among the best work done by any scientist in recent memory. Professional jealousy soon threatens Diana Skordylis's life, as some group members struggle with the urge to claim their share of the fame and separately seek out PCR's most innovative applications. Djerassi writes engagingly--and from experience--about the collaborative nature at the heart of the scientific enterprise and the desire for personal recognition in the hearts of most scientists; about the graying of Western science; and about the human frailties and humanistic concerns of its practitioners.
