Hidden away within living tissues, parasites are all around us—and inside us. Yet, despite their unsavory characteristics, as we find in this compulsively readable book, parasites have played an enormous role in civilizations through time and around the globe. Parasites: Tales of Humanity’s Most Unwelcome Guests puts amoebae, roundworms, tapeworms, mites, and others at the center of the action as human cultures have evolved and declined. It shows their role in exploration, war, and even terrorist plots, often through an unpredictable ripple effect. It reveals them as invisible threats in our food, water, and luggage; as invaders that have shaped behaviors and taboos; and as unexpected partners in such venues as crime scene investigations. Parasites also describes their evolution and life histories and considers their significant benefits. Deftly blending the sociological with the scientific, this natural and social history of parasites looks closely at a fascinating, often disgusting group of organisms and discovers that they are in fact an integral thread in the web of life.
When the cattle-borne sickness known as Mad Cow Disease first appeared in America in 2003, authorities were quick to assure the nation that the outbreak was isolated, quarantined, and posed absolutely no danger to the general public. What we were not told was that the origins of the sickness may already have been here and suspected for a quarter of a century. This illuminating exposé of the threat to our nation's health reveals for the first time how Mad Cow Disease (a.k.a. Bovine Spongiform Encephalopathy) has jumped species, infecting humans in the form of Creutzfeldt-Jakob Disease (CJD), and may be hidden in the enormous increase in the number of Alzheimer's cases since 1979. Detailing the history and biology of Mad Cow Disease, Brain Trust discloses how an investigation into the mysterious deaths in a group of cannibals in a remote part of the world evolved into a research program in the United States that may have had unforeseen and frightening consequences. The shocking questions examined include: • Have millions of Americans already been exposed to the prions known to cause Mad Cow Disease through years of eating tainted beef? • Does the epidemic of prion disease spreading like wildfire through the nation's deer and elk pose a threat to hunters and venison eaters? • Are the cattle mutilations discovered in the last 30 years part of a covert, illegal sampling program designed to learn how far the deadly prions have spread throughout the nation's livestock and beef products? Exposing the devastating truth about Mad Cow Disease and a new theory of the possible consequences of a little-known government research program and the potential national health catastrophe that may be the result, Brain Trust inoculates Americans with an effective cure: the truth.
