Interesting: ‘One of the biggest mysteries of HIV is why the virus spreads so readily via heterosexual sex in Africa, but not elsewhere. A study in monkeys suggests parasitic worms may be to blame.’
fabulous stuff: ‘The American Museum of Natural History has made available historical photographs of its exhibits… Perhaps most interesting are those showing the museum staff preparing these exhibits.’
Full title: Microcosm: E. Coli and the New Science of Life. The bacteria Escherichia coli is best known for occasionally causing food poisoning outbreaks, but most strains of it are harmless and indeed a normal part of our gut flora. It’s also one of the most-studied life forms on earth because, like fruit flies and white mice, they are used as a standard laboratory research subject. So Zimmer has been able to use E. coli as a way of looking at a whole range of related topics: evolution, cell biology, genetic engineering and so forth.
As I would expect from him, he writes clearly and well, and the book is certainly interesting, but I wasn’t as excited by it as I expected. The material was broadly familiar: I wouldn’t claim to know the subject well — I only know the bits and pieces I’ve picked up in other popular science books and New Scientist — but there weren’t that many wow moments when I learnt something surprising and new. Or perhaps it’s just that I’m not too excited by bacteria.
I do tend to find microbiology rather hard going. It’s not that it’s too conceptually difficult, I think, at least at the level it’s being presented here; it just doesn’t seem to stick in my head. I think it’s partially that I can’t visualise the action, and partially that there are all these long names for enzymes and proteins and I can’t keep track of them.
This book is pretty good, but if you haven’t read anything by Zimmer, I’d suggest you read Parasite Rex first, because that’s one of my favourite science books ever.
