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?
Being turned into a zombie is not something most of us worry about. Sure, some of us consider humans metaphorical zombies, controlled by mass media / the government / smartphone addiction / my pet hamster / ________ (fill in your own favourite 21st-century angst here). All I can say after reading Matt Simon’s book is that I am glad that I am not an insect. In turns gruesome and hilarious, Plight of the Living Dead is a carnival of the many grotesque ways that parasites can control their hosts. Something we do not have to worry about… or do we?
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.
As one of several intellectuals who wrote about evolution before Darwin, time has not been kind to the French naturalist Jean-Baptiste Lamarck (1744-1829). Reviled during his lifetime by the influential Cuvier, after his death he became best remembered, and ultimately ridiculed, for the idea that characters acquired during an organism’s lifetime are passed on to its offspring. With the rise of the modern field of epigenetics, some of his ideas are making a comeback, albeit modified and adapted for the 21st Century. Palaeontologist and astrobiologist Peter Ward would even like to go so far as to restore some honour to his name and consider epigenetics a neo-Lamarckian process.
If there is one thing that infuriates me about the way the human body works, it is the fact that our throat is a passage for both food and air. I am sure that anyone who has gone down in a fit of coughing can attest to this. As Nathan Lents shows in his amusing book Human Errors, that is just the tip of the faulty iceberg.
I recently read about the American microbiologist Carl Woese (1928-2012) and his discovery of a completely new group of single-celled organisms, the Archaea, in Quammen’s book The Tangled Tree: A Radical New History of Life. These mysterious microbes thrive under extreme environmental conditions, so I was intrigued and keen to find out more. The French microbiologist Patrick Forterre here describes these microbes, the research that led to their discovery, and the questions and answers this has thrown up. Originally published in French in 2008 as Microbes de l’Enfer, The University of Chicago Press has now made this book available in English to a wider audience.
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.
