Book review – Catching Stardust: Comets, Asteroids and the Birth of the Solar System

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.

Book review – Quarks to Culture: How We Came to Be

How did we get here? It’s a simple question, but as all parents will affirm, the simplest questions can have the most complicated answers. With Quarks to Culture, Tyler Volk, a professor in biology and environmental studies, looks at our human culture and goes all the way back to the beginning (yes, the very beginning) to ask: “Is there a pattern here?”. What follows is a book that should be taken as a spirited thought experiment.

Book review – Evolutions: Fifteen Myths That Explain Our World

Communicating the complexities and abstractions of scientific findings is not easy. Anyone who has ever slogged through yet another dense paper or muddled presentation will acknowledge this. Our universe, it seems, cares not for the human quest of understanding it. One of the things, then, that makes popular science books such a treat is that they infuse scientific findings and speculation with a certain lyricism and good storytelling. This is why we flock to authors such as Nick Lane, Richard Dawkins, Richard Fortey, and many others besides. This is why Richard Feynman and Carl Sagan remain household names decades after their death. The latter’s Pale Blue Dot segment still gives me goosebumps. With Evolutions: Fifteen Myths That Explain Our World, science historian Oren Harman boldly turns the concept on its head: rather than bringing poetic flair to a pop-science book, he brings scientific flair to an epic poem.

Book review – The Demon in the Machine: How Hidden Webs of Information Are Finally Solving the Mystery of Life

So, quick question for you. What is life?

Sorry, that’s a trick question, for the answer to this is anything but quick. The mind-boggling complexity that is life, even something as “simple” as a bacterium, somehow arises from atoms and molecules. And yet, physics and chemistry as we currently know it seem incapable of answering how life’s complexity emerges from its constituent parts. With The Demon in the Machine, well-known physicist and cosmologist Paul Davies takes a stab at it, saying we are on the verge of a breakthrough.

Book review – Kin: How We Came to Know Our Microbe Relatives

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.

Book review – Lamarck’s Revenge: How Epigenetics Is Revolutionizing Our Understanding of Evolution’s Past and Present

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.

Book review – The Tangled Tree: A Radical New History of Life

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.
