110306 The bestselling landmark account of the first emergence of the Ebola virus. A highly infectious, deadly virus from the central African rain forest suddenly appears in the suburbs of Washington, D.C. There is no cure. In a few days 90 percent of its victims are dead. A secret military SWAT team of soldiers and scientists is mobilized to stop the outbreak of this exotic "hot" virus. The Hot Zone tells this dramatic story, giving a hair-raising account of the appearance of rare and lethal viruses and their "crashes" into the human race. Shocking, frightening, and impossible to ignore, The Hot Zone proves that truth really is scarier than fiction.

110306 Inheriting the mantle of revolutionary biologist from Darwin, Watson, and Crick, Richard Dawkins forced an enormous change in the way we see ourselves and the world with the publication of The Selfish Gene. Suppose, instead of thinking about organisms using genes to reproduce themselves, as we had since Mendel's work was rediscovered, we turn it around and imagine that "our" genes build and maintain us in order to make more genes. That simple reversal seems to answer many puzzlers which had stumped scientists for years, and we haven't thought of evolution in the same way since.
Why are there miles and miles of "unused" DNA within each of our bodies? Why should a bee give up its own chance to reproduce to help raise her sisters and brothers? With a prophet's clarity, Dawkins told us the answers from the perspective of molecules competing for limited space and resources to produce more of their own kind. Drawing fascinating examples from every field of biology, he paved the way for a serious re-evaluation of evolution. He also introduced the concept of self-reproducing ideas, or memes, which (seemingly) use humans exclusively for their propagation. If we are puppets, he says, at least we can try to understand our strings. --Rob Lightner

110306 WHO DECIDES WHICH FACTS ARE TRUE?

In 1998 Andrew Wakefield, a British gastroenterologist with a history of self-promotion, published a paper with a shocking allegation: the measles-mumps-rubella vaccine might cause autism. The media seized hold of the story and, in the process, helped to launch one of the most devastating health scares ever. In the years to come Wakefield would be revealed as a profiteer in league with class-action lawyers, and he would eventually lose his medical license. Meanwhile one study after another failed to find any link between childhood vaccines and autism.

Yet the myth that vaccines somehow cause developmental disorders lives on. Despite the lack of corroborating evidence, it has been popularized by media personalities such as Oprah Winfrey and Jenny McCarthy and legitimized by journalists who claim that they are just being fair to “both sides” of an issue about which there is little debate. Meanwhile millions of dollars have been diverted from potential breakthroughs in autism research, families have spent their savings on ineffective “miracle cures,” and declining vaccination rates have led to outbreaks of deadly illnesses like Hib, measles, and whooping cough. Most tragic of all is the increasing number of children dying from vaccine-preventable diseases.

In The Panic Virus Seth Mnookin draws on interviews with parents, public-health advocates, scientists, and anti-vaccine activists to tackle a fundamental question: How do we decide what the truth is? The fascinating answer helps explain everything from the persistence of conspiracy theories about 9/11 to the appeal of talk-show hosts who demand that President Obama “prove” he was born in America.

The Panic Virus is a riveting and sometimes heart-breaking medical detective story that explores the limits of rational thought. It is the ultimate cautionary tale for our time.
110306 Henrietta Lacks, as HeLa, is known to present-day scientists for her cells from cervical cancer. She was a poor Southern tobacco farmer who worked the same land as her slave ancestors, yet her cells were taken without her knowledge and still live decades after her death. Cells descended from her may weigh more than 50M metric tons.

HeLa cells were vital for developing the polio vaccine; uncovered secrets of cancer, viruses, and the atom bomb’s effects; helped lead to important advances like in vitro fertilization, cloning, and gene mapping; and have been bought and sold by the billions. Yet Henrietta Lacks was buried in an unmarked grave.

The journey starts in the “colored” ward of Johns Hopkins Hospital in the 1950s, her small, dying hometown of Clover, Virginia — wooden slave quarters, faith healings, and voodoo. Today are stark white laboratories with freezers full of HeLa cells, East Baltimore children and grandchildren live in obscurity, see no profits, and feel violated. The dark history of experimentation on African Americans helped lead to the birth of bioethics, and legal battles over whether we control the stuff we are made of.

110306 The Nazis discovered it. The Allies won the war with it. It conquered diseases, changed laws, and single-handedly launched the era of antibiotics. This incredible discovery was sulfa, the first antibiotic. In The Demon Under the Microscope, Thomas Hager chronicles the dramatic history of the drug that shaped modern medicine.

Sulfa saved millions of lives—among them those of Winston Churchill and Franklin Delano Roosevelt Jr.—but its real effects are even more far reaching. Sulfa changed the way new drugs were developed, approved, and sold; transformed the way doctors treated patients; and ushered in the era of modern medicine. The very concept that chemicals created in a lab could cure disease revolutionized medicine, taking it from the treatment of symptoms and discomfort to the eradication of the root cause of illness.

A strange and colorful story, The Demon Under the Microscope illuminates the vivid characters, corporate strategy, individual idealism, careful planning, lucky breaks, cynicism, heroism, greed, hard work, and the central (though mistaken) idea that brought sulfa to the world. This is a fascinating scientific tale with all the excitement and intrigue of a great suspense novel.

For thousands of years, humans had sought medicines with which they could defeat contagion, and they had slowly, painstakingly, won a few battles: some vaccines to ward off disease, a handful of antitoxins. A drug or two was available that could stop parasitic diseases once they hit, tropical maladies like malaria and sleeping sickness. But the great killers of Europe, North America, and most of Asia—pneumonia, plague, tuberculosis, diphtheria, cholera, meningitis—were caused not by parasites but by bacteria, much smaller, far different microorganisms. By 1931, nothing on earth could stop a bacterial infection once it started. . . .

But all that was about to change. . . . —from The Demon Under the Microscope

110306 Dark Banquet Blood and the Curious Lives of Blood-Feeding Creatures by Bill Schutt Dark Banquet: Blood and the Curious Lives of Blood-Feeding Creatures

For centuries, blood feeders have inhabited our nightmares and horror stories, as well as the shadowy realms of scientific knowledge. In Dark Banquet, zoologist Bill Schutt takes readers on an entertaining voyage into the world of some of nature’s strangest creatures—the sanguivores. Using a sharp eye and mordant wit, Schutt makes a remarkably persuasive case that vampire bats, leeches, ticks, bed bugs, and other vampires are as deserving of our curiosity as warmer and fuzzier species are—and that many of them are even ­worthy of conservation.
Schutt takes us from rural Trinidad to the jungles of Brazil to learn about some of the most reviled, misunderstood, and marvelously evolved animals on our planet: vampire bats. Only recently has fact begun to disentangle itself from fiction concerning these remarkable animals, and Schutt delves into the myths and misconceptions surrounding them.

Examining the substance that sustains nature’s vampires, Schutt reveals just how little we actually knew about blood until well into the twentieth century. We revisit George Washington on his deathbed to learn how ideas about blood and the supposedly therapeutic value of bloodletting, first devised by the ancient Egyptians and Greeks, survived into relatively modern times. Schutt also tracks the history of medicinal leech use. Once employed by the tens of millions to drain perceived excesses of blood, today the market for these ancient creatures is booming once again—but for very different reasons.

Among the other blood feeders we meet in these pages are bed bugs, or “ninja insects,” which are making a creepy resurgence in posh hotels and well-kept homes near you. In addition, Dark Banquet details our dangerous and sometimes deadly encounters with ticks, chiggers, and mites (the ­latter implicated in Colony Collapse Disorder—currently devastating honey bees worldwide). Then there are the truly weird—vampire finches. And if you thought piranha were scary, some people believe that the candiru (or willy fish) is the best reason to avoid swimming in the Amazon.

Enlightening, alarming, and appealing to our delight in the bizarre, Dark Banquet peers into a part of the natural world to which we are, through our blood, inextricably linked.

110306 At the beginning of this century enormous progress had been made in genetics. The Human Genome Project finished sequencing human DNA. It seemed it was only a matter of time until we had all the answers to the secrets of life on this planet. The cutting-edge of biology, however, is telling us that we still don't even know all of the questions. How is it that, despite each cell in your body carrying exactly the same DNA, you don't have teeth growing out of your eyeballs or toenails on your liver? How is it that identical twins share exactly the same DNA and yet can exhibit dramatic differences in the way that they live and grow? It turns out that cells read the genetic code in DNA more like a script to be interpreted than a mould that replicates the same result each time. This is epigenetics and it's the fastest-moving field in biology today. The Epigenetics Revolution traces the thrilling path this discipline has taken over the last twenty years. Biologist Nessa Carey deftly explains such diverse phenomena as how queen bees and ants control their colonies, why tortoiseshell cats are always female, why some plants need a period of cold before they can flower, why we age, develop disease and become addicted to drugs, and much more. Most excitingly, Carey reveals the amazing possibilities for humankind that epigenetics offers for us all - and in the surprisingly near future.

110306 A Silent Spring for our era, this eloquent, urgent, fascinating book reveals how just 50 years of swift and dangerous oceanic change threatens the very existence of life on Earth. Legendary marine scientist Sylvia Earle portrays a planet teetering on the brink of irreversible environmental crisis.

In recent decades we’ve learned more about the ocean than in all previous human history combined. But, even as our knowledge has exploded, so too has our power to upset the delicate balance of this complex organism. Modern overexploitation has driven many species to the verge of extinction, from tiny but indispensable biota to magnificent creatures like tuna, swordfish, and great whales. Since the mid-20th century about half our coral reefs have died or suffered sharp decline; hundreds of oxygen-deprived "dead zones" blight our coastal waters; and toxic pollutants afflict every level of the food chain.

Fortunately, there is reason for hope, but what we do—or fail to do—in the next ten years may well resonate for the next ten thousand. The ultimate goal, Earle argues passionately and persuasively, is to find responsible, renewable strategies that safeguard the natural systems that sustain us. The first step is to understand and act upon the wise message of this accessible, insightful, and compelling book.

110306 In this book a master scientist tells the story of how life on earth evolved. Edward O. Wilson eloquently describes how the species of the world became diverse and why that diversity is threatened today as never before. A great spasm of extinction — the disappearance of whole species — is occurring now, caused this time entirely by humans. Unlike the deterioration of the physical environment, which can be halted, the loss of biodiversity is a far more complex problem — and it is irreversible. Defining a new environmental ethic, Wilson explains why we must rescue whole ecosystems, not only individual species. He calls for an end to conservation versus development arguments, and he outlines the massive shift in priorities needed to address this challenge. No writer, no scientist, is more qualified than Edward O. Wilson to describe, as he does here, the grandeur of evolution and what is at stake. "Engaging and nontechnical prose. . . . Prodigious erudition. . . . Original and fascinating insights." — John Terborgh, New York Review of Books, front page review "Eloquent. . . . A profound and enduring contribution." — Alan Burdick, Audubon

110306 DNA The Secret of Life by James D. Watson DNA: The Secret of Life

Fifty years ago, James D. Watson, then just twentyfour, helped launch the greatest ongoing scientific quest of our time. Now, with unique authority and sweeping vision, he gives us the first full account of the genetic revolution—from Mendel’s garden to the double helix to the sequencing of the human genome and beyond.
Watson’s lively, panoramic narrative begins with the fanciful speculations of the ancients as to why “like begets like” before skipping ahead to 1866, when an Austrian monk named Gregor Mendel first deduced the basic laws of inheritance. But genetics as we recognize it today—with its capacity, both thrilling and sobering, to manipulate the very essence of living things—came into being only with the rise of molecular investigations culminating in the breakthrough discovery of the structure of DNA, for which Watson shared a Nobel prize in 1962. In the DNA molecule’s graceful curves was the key to a whole new science.

Having shown that the secret of life is chemical, modern genetics has set mankind off on a journey unimaginable just a few decades ago. Watson provides the general reader with clear explanations of molecular processes and emerging technologies. He shows us how DNA continues to alter our understanding of human origins, and of our identities as groups and as individuals. And with the insight of one who has remained close to every advance in research since the double helix, he reveals how genetics has unleashed a wealth of possibilities to alter the human condition—from genetically modified foods to genetically modified babies—and transformed itself from a domain of pure research into one of big business as well. It is a sometimes topsy-turvy world full of great minds and great egos, driven by ambitions to improve the human condition as well as to improve investment portfolios, a world vividly captured in these pages.

Facing a future of choices and social and ethical implications of which we dare not remain uninformed, we could have no better guide than James Watson, who leads us with the same bravura storytelling that made The Double Helix one of the most successful books on science ever published. Infused with a scientist’s awe at nature’s marvels and a humanist’s profound sympathies, DNA is destined to become the classic telling of the defining scientific saga of our age.

110306 Between habitat loss, white-nose syndrome or wind turbines, it's tough to be a bat nowadays. Despite their creepy reputation, bats are an extremely diverse group and are ecologically very beneficial for pest insect control, pollination, and guano fertilization worldwide. (As well as providing endless fascination for bat biologists like myself).

So, in honor of bat appreciation month, I thought I'd share this article about bat "librarians" in Portugal that keep the bookworm population in check: http://www.boston.com/bostonglobe/ide...

110306 Video From "The Chemist's War" (Slate Magazine), by Deborah Blum Pulitzer Prize-winning science writer Deborah Blum follows New York City's first forensic scientists to discover a fascinating Jazz Age story of chemistry and detection, poison and murder.

Deborah Blum, writing with the high style and skill for suspense that is characteristic of the very best mystery fiction, shares the untold story of how poison rocked Jazz Age New York City. In The Poisoner's Handbook Blum draws from highly original research to track the fascinating, perilous days when a pair of forensic scientists began their trailblazing chemical detective work, fighting to end an era when untraceable poisons offered an easy path to the perfect crime.

Drama unfolds case by case as the heroes of The Poisoner's Handbook—chief medical examiner Charles Norris and toxicologist Alexander Gettler—investigate a family mysteriously stricken bald, Barnum and Bailey's Famous Blue Man, factory workers with crumbling bones, a diner serving poisoned pies, and many others. Each case presents a deadly new puzzle and Norris and Gettler work with a creativity that rivals that of the most imaginative murderer, creating revolutionary experiments to tease out even the wiliest compounds from human tissue. Yet in the tricky game of toxins, even science can't always be trusted, as proven when one of Gettler's experiments erroneously sets free a suburban housewife later nicknamed "America's Lucretia Borgia" to continue her nefarious work.

From the vantage of Norris and Gettler's laboratory in the infamous Bellevue Hospital it becomes clear that killers aren't the only toxic threat to New Yorkers. Modern life has created a kind of poison playground, and danger lurks around every corner. Automobiles choke the city streets with carbon monoxide; potent compounds, such as morphine, can be found on store shelves in products ranging from pesticides to cosmetics. Prohibition incites a chemist's war between bootleggers and government chemists while in Gotham's crowded speakeasies each round of cocktails becomes a game of Russian roulette. Norris and Gettler triumph over seemingly unbeatable odds to become the pioneers of forensic chemistry and the gatekeepers of justice during a remarkably deadly time. A beguiling concoction that is equal parts true crime, twentieth-century history, and science thriller, The Poisoner's Handbook is a page-turning account of a forgotten New York.

110306 The emergence of strange new diseases is a frightening problem that seems to be getting worse. In this age of speedy travel, it threatens a worldwide pandemic. We hear news reports of Ebola, SARS, AIDS, and something called Hendra killing horses and people in Australia but those reports miss the big truth that such phenomena are part of a single pattern. The bugs that transmit these diseases share one thing: they originate in wild animals and pass to humans by a process called spillover. David Quammen tracks this subject around the world. He recounts adventures in the field netting bats in China, trapping monkeys in Bangladesh, stalking gorillas in the Congo with the world s leading disease scientists. In Spillover Quammen takes the reader along on this astonishing quest to learn how, where from, and why these diseases emerge, and he asks the terrifying question: What might the next big one be?
