Are we alone in the universe? For the moment, this question remains unanswered, though there are many ways to tackle it. Just how many was something I did not appreciate until I sunk my teeth into Harvard University Press’s new flagship astronomy title Life in the Cosmos. Written by astrobiologist Manasvi Lingam and theoretical physicist Abraham “Avi” Loeb, this is a book of truly colossal proportions, clocking in at over 1000 pages. It boldly goes where few academic books have gone before by seriously and open-mindedly considering the possibility of extraterrestrial technological intelligence on par with, or far beyond humans. I found myself gravitating towards this book on account of more than just its size.
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.
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.
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.
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.
DNA has lodged itself in the public imagination as the “blueprint” of life and as other, often slightly deceiving, metaphors. But what happens next? How do organisms actually get anything done with the information coded in DNA? For biologists, this is standard textbook fare: DNA is copied into single-stranded RNA which is then translated, three letters at a time, into amino acids that, when strung together, make up the workhorses of the cell: proteins. The cell organ, or organelle, that does the latter part is the ribosome, which Venki Ramakrishnan introduces here in Gene Machine. He has written a riveting first-hand account of the academic race to describe its structure, and how, in the process, he bagged a shared Nobel Prize in Chemistry in 2009.
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.
