Biofuel bonanza under the microscope

While I prepare to toss part two of my own humble contribution onto the biofuel bonfire, pop on over to Biopact for a long analysis of Grist magazine’s recent series on biofuels. Biopact does a decent job of expanding Grist’s debate beyond North America. The whole “debate” seems to be doing a better job of generating hot air than biofuels at the moment, but out of this, I hope, only good can eventually emerge. Biofuel from biomass is not a panacea, but if sensibly embraced the idea could bring multiple benefits.

An apple a day

Anthocyanins make apples red, and make people healthy, through their antioxidant action. Now we know where the gene which controls anthocyanin production in apples is located, because scientists at CSIRO in Australia measured how much different genes were expressed as differently coloured fruits ripened. This opens the way for marker-assisted selection, as colour can now be predicted even in seedlings. It seems that apple sales have been pretty flat lately, but that launching a new variety can sometimes give them a boost. That could now be easier. Now if only the same sort of intensity of effort could be directed at the marula, say.

Farming tigers

Not agricultural biodiversity, but here’s a somewhat radical (in its context) take on conservation through use. Of course, this strategy is fairly well established for wild plants.
