Now award-winning writer Carl Zimmer takes us on a fantastic voyage into the secret parasite universe we actually live in but haven't recognized. He reveals not only that parasites are the most successful life-forms on Earth, but that they triggered the development of sex, shape ecosystems, and have driven the engine of evolution. In mapping the parasite universe, Zimmer makes the astonishing observation that most species are parasites, and that almost every animal, including humans, will at one time or another become the home of a parasite. Zimmer shows how highly evolved parasites are and describes the frightening and amazing ingenuity these commando invaders use to devour their hosts from the inside and control their behavior. The sinister Sacculina carcini makes its home in an unlucky crab and proceeds to eat everything but what the crab needs to put food in its mouth, which Sacculina then consumes. When Sacculina finally reproduces, it places its young precisely where the crab would nurture its own progeny, and then has the crab nurture the foster family members. Single-celled Toxoplasma gondi has an even more insidious role, for it can invade the human brain. There it makes men distrustful and less willing to submit to social mores. Women become more outgoing and warm-hearted. Why would a parasite cause these particular personality changes? It seems Toxoplasma wants its host to be less afraid, to be more prone to danger and a violent end -- so that, in the carnage, it will be able to move on to another host. From the steamy jungles of Costa Rica to the fetid parasite heaven of rebel-held southern Sudan, Zimmer tracks the genius of parasitic life and its impact on humanity. We hosts have developed remarkable defenses against the indomitable parasite: our mighty immune system, our culturally enforced habit of keeping clean, and, perhaps most intriguingly, sex. But this is not merely a book about the evil power of parasitism and how we must defend against it. On the contrary, Zimmer concludes that humankind itself is a new kind of parasite, one that preys on the entire Earth. If we are to achieve the sophistication of the parasites on display here in vivid detail, if we are to promote the flourishing of life in all its diversity as they do, we must learn the ways nature lives with itself, the laws of Parasite Rex.

    What's the mystery? The pattern crops up in the most unexpected places. You'll find it in the disk of a sunflower, the skin of a pineapple, and the spiral of a nautilus shell. No one knows how nature came up with the sequence. Sarah C. and Richard P. Campbell introduce the Fibonacci sequence through a series of stunning photographs. Young readers will soon be seeing nature through new eyes, looking for Fibonacci numbers in daisies, pinecones, leaf patterns, seashells, and more.

    Montgomery sees a rattlesnake flattened on the side of the road, her first instinct is to pick it up and dissect it--she's always wanted to see how a snake's fangs retract when they close their mouths, and it's not exactly safe to poke around in a live reptile's mouth. A wildlife researcher with a special penchant for the animals that litter the roadways, Heather isn't satisfied with dissecting just one snake. Her fascination with roadkill sets her off on a journey from her own backyard and the roadways of the American South to scientists and kids in labs and homes across the globe. From biologists who use the corpses of Tasmanian devils to investigate cures for a contagious cancer, to a scientist who discovered a whole new species of bird from a single wing left behind, to a boy rebuilding animal bodies from the bones up, to a restaurant that serves up animal remnants, Heather discovers that death is just the beginning for these creatures. This engaging narrative nonfiction is an eye-opening and irreverent look at the dead and dying animals that we pass by without a second thought--as well as a fascinating insight to the scientific research process.
