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 Feed (SF) - Nick Clark Windo ****

Ever since The War of the Worlds, the post-apocalyptic disaster novel has been a firm fixture in the Science Fiction universe. What's more, such books are often among the few SF titles that are shown any interest by the literati, probably because many future disaster novels feature very little science. With a few exceptions, though (I'm thinking, for instance, The Chrysalids) they can make for pretty miserable reading unless you enjoy a diet of page after page of literary agonising.

The Feed is a real mixture. Large chunks of it are exactly that - page after page of self-examining misery with an occasional bit of action thrown in. But, there are parts where the writing really comes alive and shows its quality. This happens when we get the references back to pre-disaster, when we discover the Feed, which takes The Circle's premise to a whole new level with a mega-connected society where all human interaction is through directly-wired connections… until the whole thing fails …

Everything You Know About Space Is Wrong - Matt Brown ****

What we have here is a feast of assertions some people make about space that are satisfyingly incorrect, with pithy, entertaining explanations of what the true picture is. Matt Brown admits in his introduction that a lot of these incorrect facts are nitpicking - more on that in a moment - but it doesn't stop them being delightful. I particularly enjoyed the ones about animals in space and about the Moon.

Along the way, we take in space exploration, the Earth's place in space, the Moon, the solar system, the universe and a collection of random oddities, such as the fact that Mozart didn't write Twinkle, Twinkle Little Star. Sometimes the wrongness comes from a frequent misunderstanding. So, for example, Brown corrects the idea that Copernicus was the first to say that the Earth moves around the Sun. Sometimes there's some very careful wording. This is used when Brown challenges the idea that the Russian dog Laika was the first animal in space. What we discover is that, i…

Dark Matter and the Dinosaurs - Lisa Randall ****

I did my PhD in galactic dynamics - which is an awkward subject when people want to know what its relevance to the 'real world' is. So I was excited when Clube and Napier's book The Cosmic Serpent came out, around the same time, because it provided me with a ready-made answer. It argued that the comets which occasionally crash into Earth with disastrous results - such as the extinction of the dinosaurs - are perturbed from their normal orbits by interactions with the large-scale structure of the galaxy.

I was reminded of this idea a few years ago when there was a flurry of media interest in Lisa Randall's "dark matter and the dinosaurs" conjecture. I was sufficiently enthusiastic about it to write an article on the subject for Fortean Times - though my enthusiasm didn't quite extend to purchasing her hardback book at the time. However, now that it's out in paperback I've remedied the situation - and I'm glad I did.

Dark matter is believed to exi…
