The Moral Molecule – Paul J. Zak *****

You wait years for a book on empathy and two come out within days. But the contrast with Simon Baron-Cohen’s book could not be greater. The Moral Molecule is popular science as rumbustious personal story telling – it is a highly enjoyable exploration of Paul Zak’s journey from economist to neurobiologist and of his almost obsessive interest in the molecule oxytocin and its influence on trust and empathy – in effect on human goodness.
Although oxytocin is the star, this is a tale of two molecules, with testosterone in the black hat to oxytocin’s white. Testosterone it seems doesn’t just counter oxytocin’s beneficial effects, it encourages us towards behaviour that could be considered evil – though to be fair to Zak things are nowhere near so black and white in reality: we need both for different reasons. But Zak makes a wonderful fist of selling the benefits of the trust and empathy that arise from an oxytocin high (even though I’m not sure I’m sold on Zak’s enthusiasm for hugs).
The final part of the book is a bit of a let down. Up to then it has been a romp of a story with lots of experiments and their outcomes. For the final section it settles down to Zak’s analysis of the likes of religion and business with an ‘oxytocin rules’ hat on. Still interesting, but much less engaging.
I really thought for the first few pages this would be one of those wince-making books where a scientist features himself as star, but actually it’s one of the best popular science books I’ve read this year. Recommended.

The God Game (SF) - Danny Tobey *****

Wow. I'm not sure I've ever read a book that was quite such an adrenaline rush - certainly it has been a long time since I've read a science fiction title which has kept me wanting to get back to it and read more so fiercely. 

In some ways, what we have here is a cyber-SF equivalent of Stephen King's It. A bunch of misfit American high school students face a remarkably powerful evil adversary - though in this case, at the beginning, their foe appears to be able to transform their worlds for the better.

Rather than a supernatural evil, the students take on a rogue AI computer game that thinks it is a god - and has the powers to back its belief. Playing the game is a mix of a virtual reality adventure like Pokemon Go and a real world treasure hunt. Players can get rewards for carrying out tasks - delivering a parcel, for example, which can be used to buy favours, abilities in the game and real objects. But once you are in the game, it doesn't want to let you go and is …

Uncertainty - Kostas Kampourakis and Kevin McCain ***

This is intended as a follow-on to Stuart Firestein's two books, the excellent Ignorance and its sequel, Failure, which cut through some of the myths about the nature of science and how it's not so much about facts as about what we don't know and how we search for explanations. The authors of Uncertainty do pretty much what they set out to do in explaining the significance of uncertainty and why it can make it difficult to present scientific findings to the public, who expect black-and-white facts, not grey probabilities, which can seem to some like dithering.

However, I didn't get on awfully well with the book. A minor issue was the size - it was just too physically small to hold comfortably, which was irritating. More significantly, it felt like a magazine article that was inflated to make a book. There really was only one essential point made over and over again, with a handful of repeated examples. I want something more from a book - more context and depth - that …

Where are the chemistry popular science books?

by Brian Clegg
There has never been more emphasis on the importance of public engagement. We need both to encourage a deeper interest in science and to counter anti-scientific views that seem to go hand-in-hand with some types of politics. Getting the public interested in science both helps recruit new scientists of the future and spreads an understanding of why an area of scientific research deserves funding. Yet it is possible that chemistry lags behind the other sciences in outreach. As a science writer, and editor of this website, I believe that chemistry is under-represented in popular science. I'd like to establish if this is the case, if so why it is happening - and what can be done to change things. 


An easy straw poll is provided by the topic tags on the site. At the time of writing, there are 22 books under 'chemistry' as opposed to 97 maths, 126 biology and 182 physics. The distribution is inevitably influenced by editorial bias - but as the editor, I can confirm …
