Creating and curing obesity

Better late than never, I guess. I’ve only just realized that the September issue of Scientific American was entitled Feast and Famine, and juxtaposed the ironic twin killer trends of hunger and obesity. Most of the material is unfortunately behind a paywall, but I have borrowed a hardcopy from a colleague and will be reading through it in the near future. If you’ve already done so and have any comments on what the various high-profile authors involved say about agrobiodiversity, let us know. One commentator has said:

This issue of Scientific American tells us there’s money to be made by creating and then curing obesity. That’s what the science approach to obesity is about and what the prevention-based approach is up against. ((I’ve borrowed my title from this article.))

Do you agree with this take?

DNA barcoding takes off

DNA barcoding is based on a gamble (or maybe a shrewd guess), and perhaps a smidgin of circular thinking: that there is a chunk of genome short enough to sequence quickly and cheaply, and which shows just enough variability for the entire sequence to be the same for all members of a species, but different for different species. Well, the gamble seems to have paid off. A suitable bit of a gene has duly been identified for both animals and plants, data are being ammassed, and there’s talk of a portable gadget being available in a few years which will read off the relevant sequence from a bit of leaf or skin or something and compare it with a database to give you the species name right there in the field.
