Book review – Alien Oceans: The Search for Life in the Depths of Space

8-minute read

This is the second of a two-part dive into the story of oceans on Earth and elsewhere, following my review of Ocean Worlds. That book gave a deep history of how our oceans shaped Earth and life on it and briefly dipped its toes into the topic of oceans beyond Earth. Alien Oceans is the logical follow-up. How did we figure out that there are oceans elsewhere? And would such worlds be hospitable to life? Those are the two big questions at the heart of this book. If there is one person fit to answer them, it is Kevin Peter Hand, a scientist at NASA’s Jet Propulsion Laboratory and their deputy chief for solar system exploration.

Book review – The Zoologist’s Guide to the Galaxy: What Animals on Earth Reveal about Aliens – and Ourselves

6-minute read

Can we predict what aliens will look like? On some level, no, which has given science fiction writers the liberty to let their imagination run wild. On another level, yes, writes zoologist Arik Kershenbaum. But we need to stop focusing on form and start focusing on function. There are universal laws of biology that help us understand why life is the way it is, and they are the subject of this book. If you are concerned that consideration of life’s most fundamental properties will make for a dense read, don’t panic, The Zoologist’s Guide to the Galaxy is a spine-tingling dive into astrobiology that I could not put down.

Book review – Other Minds: The Octopus and the Evolution of Intelligent Life

6-minute read

Peter Godfrey-Smith is popularly known as the scuba-diving philosopher and has just published his new book Metazoa, in which he plumbs the evolutionary origins of minds. In preparation for reviewing that book, I am (finally) turning my attention to his initial 2016 bestseller Other Minds. Here he beholds the octopus, only to find that, behind those eight tentacles, an intelligence quite unlike ours beholds him in turn.

Book review – Why Good People Do Bad Environmental Things

If so many people are concerned about the environment, why do we still behave in ways that harm it? Many environmentalists will quickly argue that people just do not care or need more information. Professor of Environmental Studies Elizabeth R. DeSombre here argues that these answers are often wrong or incomplete. By considering research from a range of disciplines she is looking for a fuller explanation of why we behave the way we do. Only then can we hope to change how people achieve their goals in less destructive ways. And that, she daringly concludes, does not even require people to care about the environment.
