Are trees social beings? In The Hidden Life of Trees, forester and author Peter Wohlleben convincingly makes the case that, yes, the forest is a social network.

He draws on groundbreaking scientific discoveries to describe how trees are like human families: tree parents live together with their children, communicate with them, support them as they grow, share nutrients with those who are sick or struggling, and even warn each other of impending dangers.

Do bacteria have moral understanding? Do fleas have emotions? Such questions are meaningful, especially when, as MacArthur Fellow Sapolsky writes, it is possible to describe some of the actions of E. coli as altruistic.

A distinguished primatologist, the author works broadly in the life and social sciences to examine human behavior, manifestations of which, he writes, belong to the nervous system and to sensory stimuli—and all of which make for a “big sprawling mess of a subject.”

Thus, this fittingly long book, which opens with the problem of defining terms—aggression, sympathy, even love—and proceeds by exploring every nook and cranny. Some of our behavior is purely mechanical, with payoffs in dopamine, that “invidious, rapidly habituating reward.”

Other aspects are located at the intersection of nature and nurture, as with the plummeting U.S. crime rate in the 1990s.

As the narrative progresses, it ascends into headier realms, examining problems both biologically and philosophically. Can there be a science of morality? If so, how is it best addressed?

An exemplary work of popular science, challenging but accessible.

An Immense World by Ed Yong delves readers into a world greater than their own: the world of animals big and small. Yong explores the many different types of senses found in the animal kingdom, and focuses on one category per chapter.

In each chapter, he discusses not only the facts that scientists know, but also how they came to know them as facts, including what observations and experiments led to conclusions. Furthermore, he explores what scientists don’t know, and is transparent in the fact that the field of science exists to explore new ideas and the unknown, not discuss things already known.

Yong has written a wonderful book that is easy and fun to read, allowing students to stay engaged with the book so they can gain the most from the science in it.

Some helpful hints:

Read the instructions! Do exactly what they tell you to do.

Use your straw to hole-punch about 12 leaf discs per experimental setup, then try to pull air from all 12. That way, if one is still floating or gets destroyed, you’ll still be able to load

10 per cup.
