Animal Science

When Jennifer Doudna was a sixth grader in Hilo, Hawaii, she came home from school one afternoon and found a book on her bed. It was The Double Helix, James Watson’s account of how he and Francis Crick had discovered the structure of DNA, the spiral-staircase molecule that carries the genetic instruction code for all forms of life. This book guided Jennifer Doudna to focus her studies not on DNA, but on what seemed to take a backseat in biochemistry: figuring out the structure of RNA, a closely related molecule that enables the genetic instructions coded in DNA to express themselves.

When Emory University neuroscientist Gregory Berns and his wife decided to venture into sustainable farming in rural Georgia, they knew that cows were a key part of a successful operation. But that was where his knowledge of cattle ended. As Berns and his small herd of three miniature zebus acclimated to each other and Berns received a crash course in being a cattleman, he turned his powers of scientific observation and innovation on his new charges. Cowpuppy offers a deeper understanding of these complex creatures and what we humans can learn from them.

The domestic cat—your cat—has, from its evolutionary origins in Africa, been transformed in comparatively little time into one of the most successful and diverse species on the planet. Jonathan Losos, writing as both a scientist and a cat lover, explores how researchers today are unraveling the secrets of the cat, past and present, using all the tools of modern technology, from GPS tracking (you’d be amazed where those backyard cats roam) and genomics (what is your so-called Siamese cat . . . really?) to forensic archaeology.

To flourish, humans need to develop virtues of independent thought and acknowledged social dependence. In this book, a leading moral philosopher presents a comparison of humans to other animals and explores the impact of these virtues.

Insects are the most successful group of animals ever to have lived. They comprise a million species and perhaps 10 quintillion individuals: one in every four animals on the planet is a beetle; one in every ten is a butterfly or moth. Much of life on earth depends on the activities of these busy, teeming arthropods, from pollination to the breaking down of waste matter. In Alien Worlds, Steve Nicholls draws on a lifetime of writing about, photographing and filming the natural world to create an ambitious account of insect evolution and biology

Princess Harriet has absolutely no interest in brushing her hair, singing duets with woodland animals, or any other typical princess activities. So when a fairy tells a very bored Harriet about 12 mice princesses who are cursed to dance all night long, she happily accepts the quest and sets off with a poncho of invisibility and her trusty battle quail. But when she arrives at the Mouse Kingdom, she discovers there's more to the curse than meets the eye, and trying to help is dangerous business...even for a tough princess like Harriet.

A turkey is the centerpiece of countless Thanksgiving and Christmas dinners. Yet most of us know almost nothing about today's specially bred, commercially produced birds. In this brief book, bestselling author Peter Singer tells their story—and, unfortunately, it's not a happy one. Along the way, he also offers a brief history of the turkey and its consumption, ridicules the annual US presidential "pardon" of a Thanksgiving turkey, and introduces us to "a tremendously handsome, outgoing, and intelligent turkey" named Cornelius. Above all, Singer explains how we can improve our holiday tables.

Racehorses with Tourette's syndrome, spinning dogs with epilepsy, cats with obsessive-compulsive disorder, feather-plucking parrots with anxiety, and a diffident bull terrier with autism - these astonishing cases were all helped by One Medicine, which emphasizes the similarities, rather than differences, between animals and humans. Inspiring, sometimes heartbreaking, and utterly fascinating, Pets on the Couch demonstrates how what we share with our animals can only lead us to a greater appreciation for them - and for our mutual bonds.
