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 – The Cheating Cell: How Evolution Helps Us Understand and Treat Cancer

7 -minute read

Fifty years ago, US President Richard Nixon declared a “war on cancer” when he signed the National Cancer Act. Despite fantastic progress on some fronts, overall it is clear that we are not winning this battle. Cancer remains one of the leading causes of human mortality. But what if the tired war-metaphor is getting it all wrong? Brimming with thought-provoking questions, The Cheating Cell looks at cancer through an evolutionary lens and forces the reader to radically reconsider cancer; not as a bug, but as a feature of life.

Book review – On the Origin of Evolution: Tracing ‘Darwin’s Dangerous Idea’ from Aristotle to DNA

8-minute read

History will forever associate Charles Darwin with the theory of evolution, but the idea was in the air. Had not Darwin published his famous book, someone else would have likely snatched the prize. Husband-and-wife duo John and Mary Gribbin here examine the wider milieu in which Darwin operated and the many thinkers who preceded him. Given their previous collaborations, the first two parts of On the Origin of Evolution read like a well-oiled machine, but the book falters when they turn their eyes to the legacy of Darwin’s ideas.

Book review – Life Changing: How Humans Are Altering Life on Earth

7-minute read

Ever since humans appeared on the scene, we have been altering life on Earth. Where once our actions could be considered part of nature’s fabric, our influence has become outsized and our options to exercise it have multiplied. Though the subtitle of Life Changing does not make it explicit, science writer Helen Pilcher focuses on our impact on the genetics and evolution of life around us. A book that stands out for its balanced tone, it managed to surprise me more than once, despite my familiarity with the topics considered.

Book review – The Story of Evolution in 25 Discoveries: The Evidence and the People Who Found It

6-minute read

After three previous books in this format on fossils, rocks, and dinosaurs, geologist and palaeontologist Donald R. Prothero here tackles the story of evolution in 25 notable discoveries. More so than the previous trio, this book tries to be a servant to two masters, resulting in a mixed bag.

Book review – The Genesis Quest: The Geniuses and Eccentrics on a Journey to Uncover the Origin of Life on Earth

8-minute read

The Genesis Quest is one of those books that quickly makes a good case for its own existence. It takes the reader through the century-long research endeavour on the origin of life, providing a big-picture overview of who’s who and how their ideas have waxed and waned. Such an overview requires an outsider’s perspective on the whole show, which is exactly what science writer Michael Marshall achieves in my opinion. A superb starting point if you want to read more on this subject, this is the book I wish I had read earlier.

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 – What Is Health? Allostasis and the Evolution of Human Design

10-minute read

Advances in medical research mean we have come to grips with numerous diseases and health conditions over the decades. But, like a game of whack-a-mole, you solve one set of problems to only have other, often more complex problems take their place. There is valid criticism to be had of medicine and its reductionist approach and What Is Health? sees neurobiologist Peter Sterling offer a critique grounded in physiology.

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 – Vampirology: The Science of Horror’s Most Famous Fiend

6-minute read

You would think that science and monsters are strange bedfellows. And yet, there are plenty of science geeks, myself included, who get a good giggle out of pondering the science behind mythical beings and worlds. Clearly, somebody at the Royal Society of Chemistry has a similar sense of humour, for they have just published Vampirology. Here, chemist and science communicator Kathryn Harkup trains a scientific lens on the fanged fiend – not so much to ask whether vampires do or do not exist, but whether they could exist given our scientific understanding today.
