This new edition, written with five new authors, has been brought fully up to date, and incorporates insights very recently derived from genome sequencing in a variety of organisms. The book is an authoritative and comprehensive survey of the fundamentals of molecular biology, from basic mechanisms to the elaborate role of gene regulation in embryonic development and evolution. Although updated, the twentyone chapters of the new edition retain the distinctive and celebrated features of the original work, including introductory chapters on the history of genetics and molecular biology and an emphasis throughout on the chemical underpinnings of molecular biology. The new team of authors brings to this edition awardwinning teaching experience and outstanding research achievements. By revealing the intellectual framework and experimental approaches that made new discoveries in the field possible, the new edition highlights the significance of the molecular approach for all of biology.

    And we all have stories.The bite attacks that Pamela Nagami, M.D., has chosen to write about in Bitten take place in big cities, small towns, and remote villages around the world and throughout history, locales as familiar as New York or Hollywood, or exotic as Africa, the Middle East, or Indonesia. They include a six-year-old girl who descended into weeks of extreme lassitude from a tick bite; a diabetic in the West Indies who awoke to find a rat eating two of his toes; a California man who developed "flesh-eating strep" following a penile bite; and more.With reports from medical journals, case histories, colleagues, and her own twenty-five-year career as a practicing physician and infectious diseases specialist, Pamela Nagami offers readers intrigued by infection, disease, and mesmerized by creatures in the wild a compulsively readable narrative that is entertaining, sometimes disturbing, and always engrossing.

    Its job is to protect us from cancer. This gene--known simply as p53--constantly scans our cells to ensure that when they grow and divide as part of the routine maintenance of our bodies, they do so without mishap. If a cell makes a mistake in copying its DNA during the process of division, p53 stops it in its tracks, sending in the repair team before allowing the cell to carry on dividing. If the mistake is irreparable and the rogue cell threatens to grow out of control (as happens in cancer), p53 commands the cell to commit suicide. Cancer cannot develop unless p53 itself is damaged or handicapped by some other fault in the system. Not surprisingly, p53 is the most studied single gene in history. p53: The Gene that Cracked the Cancer Code tells the story of the discovery of the gene and of medical science's mission to unravel its mysteries and get to the heart of what happens in our cells when they turn cancerous. Through the personal accounts of key researchers, the book reveals the excitement of the hunt for new cures--the hype, the enthusiasm, the lost opportunities, the blind alleys and the thrilling breakthroughs. As the long-anticipated revolution in cancer treatment tailored to each individual patient's symptoms starts to take off at last, p53 is at the cutting edge. This is a timely tale of scientific discovery and advances in our understanding of a disease that still affects more than one in three of us at some point in our lives.

     Early studies of the functions of the human brain used a simple method: wait for misfortune to strike-strokes, seizures, infectious diseases, lobotomies, horrendous accidents-and see how the victim coped. In many cases survival was miraculous, and observers could only marvel at the transformations that took place afterward, altering victims' personalities. An injury to one section can leave a person unable to recognize loved ones; some brain trauma can even make you a pathological gambler, pedophile, or liar. But a few scientists realized that these injuries were an opportunity for studying brain function at its extremes. With lucid explanations and incisive wit, Sam Kean explains the brain's secret passageways while recounting forgotten stories of common people whose struggles, resiliency, and deep humanity made modern neuroscience possible.
