Herding Hemingway's Cats - Kat Arney ****

It's a book about cats, then? No, it isn't - but the author Ernest Hemingway gets a mention because at Key West he had a penchant for cats with a genetic variation that gave them an extra toe. (Apparently this is a myth, as Hemingway didn't have cats in Key West, but it's a good story.) Ah, I've got it - the title is a pun. The author's called Kat and the title says Cats. It's a joke. Nope. Okay, it's an attempt to duplicate the success of the rather similarly titled "In Search of Schrödinger's Cat"? That certainly might be the reasoning behind the title, but it's actually about the bizarre complexity of molecular biology, the weird and wonderful mechanisms that make use of DNA and RNA to develop living organisms and to keep them healthy.

 That 'bizarre complexity' part is no exaggeration. The real fascination of this book - and it truly is fascinating - lies in the Byzantine convolutions employed by living systems at the sub-cellular level. Kat Arney beautifully documents what is surely the ultimate counter to any suggestion that living organisms were designed, as they never seem to take a single, simple step to achieve something where seven complex back and forth interactions could achieve the same result. As a non-biologist I had previously been amazed by the sophistication of the molecular machinery in complex cells, but I had no idea just how messy and disorganised the whole interaction between DNA and RNA to produce proteins, switch genes on and off, splice bits of molecule here and there and generally get something remarkable out of apparent chaos is. Heath Robinson had nothing on biology - it's amazing that anything living survives.

 Arney presents the information in an extremely chatty and informal style. It works well that much of the book is based around a series of interviews with leading scientists in the field, as it gives a chance for personalities to emerge in what is inevitably a description-heavy topic. In fact, if anything, the writing style was just a touch too informal for me - I suspect many will really enjoy Arney's pithy asides, but sometimes, comments like 'you may wish to ponder this tale the next time you're in close proximity to a penis. I know I will.' struck me as trying just a little bit too hard.

 The biggest problem here, which is not entirely helped by the format, is that in the end, amazing and fascinating though the mechanisms involved in manipulating DNA and RNA are, in the end we get page after page of descriptions of how molecules behave, and even the core fascination of the complexity, and the interesting people, can't always stop this feeling distinctly repetitive. The way the presentation is based on various interviews doesn't help here, because it means what is already a random and confusing story is not presented in a logical order based on the science, so the chance of getting blinded by the science is increased. I'd also pick up Arney on her own comment 'It's just as true in science as it is elsewhere in life that a picture is worth a thousand words' - so why aren't there any? There is not a single illustration in the book, and some of the things she describes cry out for a good diagram. If you aren't a biologist, it's easy to struggle to visualise what is being described.

 Nonetheless, this a great addition to the rapidly growing field of books giving us an insight into just how complex biology is at the molecular level, and I feel privileged to have indirectly met these interesting people via Arney's interviews. While the material itself can get a touch samey, that goes with the territory - and otherwise it's a great piece of popular science.

The Genetic Book of the Dead: Richard Dawkins ****

When someone came up with the title for this book they were probably thinking deep cultural echoes - I suspect I'm not the only Robert Rankin fan in whom it raised a smile instead, thinking of The Suburban Book of the Dead . That aside, this is a glossy and engaging book showing how physical makeup (phenotype), behaviour and more tell us about the past, with the messenger being (inevitably, this being Richard Dawkins) the genes. Worthy of comment straight away are the illustrations - this is one of the best illustrated science books I've ever come across. Generally illustrations are either an afterthought, or the book is heavily illustrated and the text is really just an accompaniment to the pictures. Here the full colour images tie in directly to the text. They are not asides, but are 'read' with the text by placing them strategically so the picture is directly with the text that refers to it. Many are photographs, though some are effective paintings by Jana Lenzová. T

Everything is Predictable - Tom Chivers *****

There's a stereotype of computer users: Mac users are creative and cool, while PC users are businesslike and unimaginative. Less well-known is that the world of statistics has an equivalent division. Bayesians are the Mac users of the stats world, where frequentists are the PC people. This book sets out to show why Bayesians are not just cool, but also mostly right. Tom Chivers does an excellent job of giving us some historical background, then dives into two key aspects of the use of statistics. These are in science, where the standard approach is frequentist and Bayes only creeps into a few specific applications, such as the accuracy of medical tests, and in decision theory where Bayes is dominant. If this all sounds very dry and unexciting, it's quite the reverse. I admit, I love probability and statistics, and I am something of a closet Bayesian*), but Chivers' light and entertaining style means that what could have been the mathematical equivalent of debating angels on

David Spiegelhalter Five Way interview

Professor Sir David Spiegelhalter FRS OBE is Emeritus Professor of Statistics in the Centre for Mathematical Sciences at the University of Cambridge. He was previously Chair of the Winton Centre for Risk and Evidence Communication and has presented the BBC4 documentaries Tails you Win: the Science of Chance, the award-winning Climate Change by Numbers. His bestselling book, The Art of Statistics , was published in March 2019. He was knighted in 2014 for services to medical statistics, was President of the Royal Statistical Society (2017-2018), and became a Non-Executive Director of the UK Statistics Authority in 2020. His latest book is The Art of Uncertainty . Why probability? because I have been fascinated by the idea of probability, and what it might be, for over 50 years. Why is the ‘P’ word missing from the title? That's a good question.  Partly so as not to make it sound like a technical book, but also because I did not want to give the impression that it was yet another book
