Sea otters don’t eat algae. And yet, their diet influences the abundance of seaweed. How? Indirectly. Sea otters eating sea urchins (spiky animals in the same class as sea stars) eating kelp has become a textbook example of a trophic cascade, and Serendipity is a first-hand account by ecologist James A. Estes of how this happened. A trophic cascade refers to the indirect effects that ripple through a food web as a result of, for example, a predator consuming its prey. Simultaneously, the book is a searingly open account of how science is done, how ideas change, and how fortuitous events can suddenly send your research programme off in a whole new direction.
Underground spaces exert a strong pull on the imagination of most people, although for some this morphs into a fascination bordering on the obsessive. American author Will Hunt is one such person, part of a worldwide community of urban explorers who infiltrate into “the city’s obscure layers”. Though this encompasses more than underground spaces, they are a big part of it, and this book is Hunt’s story of how he fell in love with them. It is one of two big books published only five months apart on the subterranean realm, and I previously reviewed Robert Macfarlane’s Underland: A Deep Time Journey. Here I will turn my attention to Underground.
Shelter. Yield. Dispose.
These three tasks, so says nature writer Robert Macfarlane, signify our relationship with the world beneath our feet, both across time and across cultures. Underland is his lyrical exploration of underground spaces where people have sought shelter from warfare or hidden valuable treasures, are extracting minerals in mines or knowledge in research facilities, or are looking to dispose of waste. It is one of two big books published only five months apart on the subterranean realm, the other being Will Hunt’s Underground: A Human History of the Worlds Beneath Our Feet which I will be reviewing next. But first, Underland.
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?
Since being released on the world in 2012, the biotechnological tool CRISPR has been making headlines. Biologists used to rely on the relatively blunt tools of genetic modification, but this new tool is so precise and versatile that they now speak of gene editing instead. For people in a hurry, Nessa Carey here provides a primer on the powers and pitfalls of gene editing. Hacking the Code of Life is accessible to readers without much background in genetics, focusing more on the applications and the questions it raises than the nitty-gritty details of the tool itself.
“Why, of all the species that have ever existed, have only us humans reached this unparalleled level of social organisation?” Sounds familiar? I indeed opened my review of E.O. Wilson’s recent book Genesis: On the Deep Origin of Societies with almost these exact words. Where that book (quite literally) fell a bit short of the intended mark, biologist Mark W. Moffett here delivers a sprawling big history book that considers almost the same question. Perhaps this should not come as a surprise, for Wilson has been Moffett’s mentor.
Given that I consider overpopulation to be the mother of all problems and, unfortunately, the elephant in the room that few wish to address, this book immediately drew my attention. Empty planet? Global population decline? Those are not words you often hear when the subject turns to future demographic trends. And yet, these two Canadian authors, Darrell Bricker the CEO of social and opinion research firm Ipsos Public Affairs and John Ibbitson a journalist for Globe and Mail, contend exactly this.
Asteroids and comets have a bad reputation. Looking back over the books I have reviewed, they usually come up in the context of impact and destruction. But there are other important reasons to study them and geologist and cosmochemist Natalie Starkey here steps up as their enthusiastic spokeswoman. Whether as frozen time capsules, possible vehicles dispersing the basic chemicals required for life, or even future mining quarries, Catching Stardust champions the importance of scientific research on these celestial objects.
Why, of all the species that have ever existed, have only us humans reached this unparalleled level of intelligence and social organisation? When a senior scientist such as Edward O. Wilson trains his mind on such a question, you hope to be in for a treat.
Long-term readers of this blog will be aware that the proliferation of pseudoscience and anti-scientific sentiments disturb me deeply. As someone with a scientific training, my concerns are foremost academic. But as the contributors to this edited collection wish to show, these anti-intellectual trends also impact democracy. This is perhaps nowhere more pronounced than in the USA and Anti-Science and the Assault on Democracy is therefore appropriately US-centric. It is also rather academic and scholarly in tone, more so than other works aimed at a general audience.
