Viruses are possibly even more maligned than bacteria, spoken of exclusively in terms of disease. Here, virologist Marilyn J. Roossinck ranges far beyond human pathogens to convince you how narrow that picture is. She instead reveals them as enigmatic entities that are intimately entwined with the entirety of Earth’s biosphere, exploiting and enabling it in equal measure. Backed by numerous infographics, the book alternates between chapters on basic principles of virology and brief portraits of noteworthy viruses. The result is an entry-level introduction to virology that fascinated me more than I expected.
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.
In the wake of the COVID-19 pandemic, many publishers have seen an opportunity to reissue previously published books on viruses and pandemics. As a reader, it is always difficult to know whether you are actually getting any updated content beyond the obligatory new preface or afterword, or whether this is just a quick cash-grab. Fortunately, the third edition of Carl Zimmer’s famous virology primer A Planet of Viruses is here to prove those suspicions wrong.
In the already unusual world of viruses, retroviruses stand out for being even more so. Called “retro” because they reverse the flow of genetic information from RNA to DNA, rather than the normal DNA to RNA, they have turned out to be ancient, omnipresent, and incredibly influential. They are also important as they cause diseases such as AIDS. With Discovering Retroviruses, Anna Marie Skalka delivers a book dedicated to this particular group that is as technical as it is fascinating.
Beware the virus. If there is one message physician and evolutionary biologist Frank Ryan is hammering home with this book, it is this. Viruses are absolutely everywhere and more numerous even than microbes. So much so that Ryan speaks of the virosphere rather than the biosphere. But more than harbingers of disease, they are also agents of evolutionary invention. Now why does that sound familiar?
The problem with many history books is that they are written long after the facts, sometimes when the original protagonists are no longer alive. Historians or journalists often have no choice but to puzzle together the pieces of their story from eyewitness testimony or archival sources. Kin: How We Came to Know Our Microbe Relatives is a welcome exception to this rule. Written by emeritus microbiology professor John L. Ingraham, currently 94 years young, this book gives an intellectual history of the discipline of microbiology based on over seven decades of first-hand involvement and observation.
The term “wildlife” tends to evoke images of apex predators, cuddly creatures, or flagship species – usually vertebrate, usually mammalian – living outdoors in the wilderness of jungles, plains, or oceans. But what about closer to home? What about in your home? Ecologist Rob Dunn has written a delightful book showing that we live amidst a veritable zoo.
After I recently finished Carl Zimmer’s new book She Has Her Mother’s Laugh: The Powers, Perversions, and Potential of Heredity, I noticed there was one mechanism of heredity he mentioned only ever so briefly: horizontal gene transfer. Since it does not play a large role in humans, it is understandable he left it aside. And doing it justice would have required almost another book. Luckily, science writer David Quammen is here to give us that book.
If Charles Darwin were to walk into my office today and ask me: “So, what did I miss?” I think I would sit the good man down with a copy of She Has Her Mother’s Laugh, telling him: “Here, this should get you up to speed”. Darwin struggled to explain how traits were being inherited from generation to generation. As New York Times columnist Carl Zimmer shows in this wide-ranging book, the story of heredity has turned out to be both diverse and wonderful, but has also been misappropriated to prop up some horrible ideologies.
When I reviewed Planet of Microbes: The Perils and Potential of Earth’s Essential Life Forms, I remarked that microbes are everywhere. If you are willing to stretch the definition of life a bit further still, there is one entity that is even more numerous and omnipresent: the humble virus. We tend to think of viruses almost exclusively in the context of disease (see for example The Invisible Enemy: A Natural History of Viruses). But, as virologist and pharmaceutical researcher Michael Cordingley shows here, they are so much more than mere pathogens and have a huge influence on evolutionary processes in all organisms. This book paints a remarkable portrait of these unusual life forms.
