Book review – Life’s Edge: The Search for What It Means to Be Alive

7-minute read

The word biology derives from the Greek words bíos (βίος in Greek), meaning “life”, and -logía (-λογία in Greek), meaning “branch of study”, and is usually defined as “the study of life”. But what is life? Remarkably, biologists cannot agree on a definition. Everyone can name clear examples of living and non-living things. However, as so often in biology, there is no sharp demarcation between the two. There is a grey area where things are, well, somewhat alive? Lifelike? It is these borderlands between life and non-life that famous science writer and journalist Carl Zimmer explores in Life’s Edge. Instead of providing an answer, this intellectually stimulating and rewarding book will help you understand why it is such a hard question to begin with.

Book review – Fossilization: Understanding the Material Nature of Ancient Plants and Animals

6-minute read

Fossils are our prime source of information about life in the past. As I delve deeper into palaeontology and earth sciences, the process of fossilisation increasingly fascinates me. How does dead biological tissue fossilise? What information is lost, what is added, and what is distorted in the process? And, ultimately, how true or filtered a picture of past life does the fossil record provide? The edited book Fossilization brings together scientists from a range of disciplines working on cutting-edge topics. The result is a well-written if somewhat eclectic collection of chapters that addressed some of my queries and also answered questions I did not even know I had.

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 – Symphony in C: Carbon and the Evolution of (Almost) Everything

Many works of popular science claim to be histories of almost everything or everyone, but earth scientist Robert M. Hazen might actually be in the position to stake that claim. Whether you are talking stellar evolution, the origin of life, organic chemistry, synthetic materials, or hydrocarbon fuels – the multifaceted atom carbon is ubiquitous and pervasive. Symphony in C is a whirlwind tour through geology, biochemistry, and evolutionary biology that is an incredibly absorbing read, although in places it almost comes apart at the seams under the intensity of its enthusiasm.
