Living at the limits of our ordinary perception, mosses are a common but largely unnoticed element of the natural world. Gathering Moss is a beautifully written mix of science and personal reflection that invites readers to explore and learn from the elegantly simple lives of mosses.

In this series of linked personal essays, Robin Wall Kimmerer leads general readers and scientists alike to an understanding of how mosses live and how their lives are intertwined with the lives of countless other beings. Kimmerer explains the biology of mosses clearly and artfully, while at the same time reflecting on what these fascinating organisms have to teach us.

Drawing on her diverse experiences as a scientist, mother, teacher, and writer of Native American heritage, Kimmerer explains the stories of mosses in scientific terms as well as in the framework of indigenous ways of knowing. In her book, the natural history and cultural relationships of mosses become a powerful metaphor for ways of living in the world.

In recent decades immunology has been one of the most exciting--and successful--fields of biomedical research. Over the past thirty years immunologists have acquired a detailed understanding of the immune system's unique recognition mechanism and of the cellular and chemical means used to destroy or neutralize invading organisms. This understanding has been formulated in terms of the clonal selection theory, the dominant explanation of immune behavior. That story is the subject of The Generation of Diversity.

A major problem for immunologists had long been to determine how cells of the immune system could produce millions of distinct antibodies--and produce them on demand. The clonal selection theory explains that cells with genetic instructions to produce each antibody exist in the body in small numbers until exposure to the right molecule--the antigen--triggers the selective cloning that will reproduce exactly the cell needed. But how can so many different antibody-producing cells be generated from such limited genetic material? The solution to this question came from new applications of molecular biology, and, as the authors argue, the impact of the new techniques changed both the methods and the concepts of immunology.

The Generation of Diversity is an intellectual history of the major theoretical problem in immunology and its resolution in the post-World War II period. It will provide for immunologists essential background for understanding the conceptual conflicts occurring in the field today.

From simple reflexes to complex choreographies of movement, all animal behavior is governed by a nervous system. But what kind of government is it—a dictatorship or a democracy?

Nervous systems consist of circuits of interconnected nerve cells (neurons) that transmit and receive information via electrical signals. Every moment, each neuron adds up stimulating and inhibiting inputs from many other neurons to determine whether to send an electrical signal to its recipients. Some circuits are dominated by a single “dictator” neuron that gathers information from many sources and then issues commands, such as the Mauthner neuron that triggers escape in fish. In other more “democratic” circuits, such as those mediating eye movements in monkeys, the outcome is determined by a tally of “votes” from a large population of neurons. Rhythmic movements like breathing and locomotion are generated by “government programs” within the central nervous system, but modified by a soup of chemicals and by free market–like feedback from sensory neurons. Nervous systems also use sophisticated surveillance of the surrounding environment and keep track of their own decisions in order to avoid internal conflicts. Nervous systems are not restricted to using one set of procedures at a time. They have evolved over long periods to control behaviors in whichever ways are most effective, and they essentially combine multiple forms of government simultaneously.

Engaging and accessible, Governing Behavior explains the variety of structures and strategies that control behavior, while providing an overview of thought-provoking debates and cutting-edge research in neurobiology.

"Endless forms most beautiful and most wonderful have been, and are being, evolved," Darwin famously concluded The Origin of Species, and for confirmation we look to...the guinea pig? How this curious creature and others as humble (and as fast-breeding) have helped unlock the mystery of inheritance is the unlikely story Jim Endersby tells in this book.

Biology today promises everything from better foods or cures for common diseases to the alarming prospect of redesigning life itself. Looking at the organisms that have made all this possible gives us a new way of understanding how we got here--and perhaps of thinking about where we're going. Instead of a history of which great scientists had which great ideas, this story of passionflowers and hawkweeds, of zebra fish and viruses, offers a bird's (or rodent's) eye view of the work that makes science possible.

Mixing the celebrities of genetics, like the fruit fly, with forgotten players such as the evening primrose, the book follows the unfolding history of biological inheritance from Aristotle's search for the "universal, absolute truth of fishiness" to the apparently absurd speculations of eighteenth-century natural philosophers to the spectacular findings of our day--which may prove to be the absurdities of tomorrow.

The result is a quirky, enlightening, and thoroughly engaging perspective on the history of heredity and genetics, tracing the slow, uncertain path--complete with entertaining diversions and dead ends--that led us from the ancient world's understanding of inheritance to modern genetics.
