Bloom - Ruth Kassinger ***

There is much fascinating material in this chunky book by Ruth Kassinger. It may be my total ignorance of biology and everyone else knows these things, but I learnt so much - for example that seaweed is algae and not a plant, about algae's role in the development of land plants, about the algae in lichen and its contribution to coral reefs.

The book is divided into four broad sections: on the origins and development of algae, on algae (and particularly seaweed) as food, on making use of algae, for example, for biofuel, and on algae and climate change, particularly the bleaching of coral and algal blooms. This is all done in a very approachable writing style, mixing descriptive material that is never over-technical with narrative often featuring visits to different locations and to talk to a range of experts from those who study to algae to those who cook them.

There are two problems though. Firstly, the book is too long at 380 pages. Each section could do with a trim, but this was particularly obvious on the section on eating seaweed. Although I'm not a fan of the stuff, I can see the dietary appeal of seaweed, and eating algae and the processes of growing it could easily have sustained 20 pages - but instead we get 76 (with passing mentions elsewhere).

The other issue was one of timing. I happened to read this book soon after Mike Berners-Lee's There is No Planet B and Seth Wyne's SOS. Given that Kassinger makes a big (and sensible) point on the need to take action on climate change, I'm just not comfortable any more with popular science titles where the author jets from location to location just to talk to do research and have an experience. The reality is that a single long haul return flight has the same carbon footprint as around one third of a UK citizen's footprint for a whole year. We can't lecture people on climate change and continue to fly like this.

Berners-Lee also makes the point that biofuels are a ludicrously inefficient way to harness the Sun's energy. An electric car could get 200 times the range out of the solar energy from a field as a petrol car could from the fuel produced from it. The figures may differ a little for algae - but not that much. Kassinger makes the point that we will still need fuel for ships and planes, but hydrogen is likely to be a far better alternative than carbon fuels where using these is necessary.

Despite these concerns, there's a lot to like in this book and I'm glad I read it.

The Decline and Fall of the Human Empire - Henry Gee ****

In his last book, Henry Gee impressed with his A (Very) Short History of Life on Earth - this time he zooms in on one very specific aspect of life on Earth - humans - and gives us not just a history, but a prediction of the future - our extinction. The book starts with an entertaining prologue, to an extent bemoaning our obsession with dinosaurs, a story that leads, inexorably towards extinction. This is a fate, Gee points out, that will occur for every species, including our own. We then cover three potential stages of the rise and fall of humanity (the book's title is purposely modelled on Gibbon) - Rise, Fall and Escape. Gee's speciality is palaeontology and in the first section he takes us back to explore as much as we can know from the extremely patchy fossil record of the origins of the human family, the genus Homo and the eventual dominance of Homo sapiens , pushing out any remaining members of other closely related species. As we move onto the Fall section, Gee gives ...

The Autobiography – Charles Darwin ****

I have to confess to putting off reading this book until the last moment, as I expected it to be a typical piece of Victorian sentimental unreadable stodge. I was wrong. Darwin’s little book (only 150 small pages with appendices) was originally written for his own children, and displays a very personal style of writing – though, as son Francis comments, his style was always more populist than was common then: “In writing he sometimes showed the same strong tendency to strong expressions that he did in conversation. Thus in the Origin, p440, there is a description of a larvel [sic] cirripede ‘with six pairs of beautifully constructed natatory legs, a pair of magnificent compound eyes and extremely complex antennae’. We used to laugh at him for this sentence, which we compared to an advertisement.” The main book is delightful because it demonstrates Darwin’s self-depreciating modesty, and the fascinating path he took from enthusiastic shooter of game, to amateur geologist (still his...

The Premonitions Bureau - Sam Knight ****

Not everyone would class this as popular science, but it concerns an attempt to take a scientific approach to paranormal abilities - notably premonitions (aka clairvoyance) and as such, it fits the category. Writing in the typical dramatic storytelling style of a US magazine, Sam Knight brings to life the remarkable tale of the work of two British figures from the 1960s. The central one is psychiatrist John Barker, with a supporting role given to newspaper and TV science reporter Peter Fairley. Barker had a long interest in extra sensory phenomena - the story takes off when he was inspired by a number of people claiming to have foreseen the Aberfan disaster (which terrible tragedy Knight covers movingly). As a result of the Aberfan premonitions, the pair were responsible for London's Evening Standard newspaper setting up a long-running experiment in the form of 'The Premonitions Bureau.' Aware that the Aberfan predictions were only reported after the event, and hence flawe...
