There is a another GM story (http://www.newscientist.com/article/dn15040-purple-tomatoes-could-ward-off-cancer.html) about UK scientists (at the John Innes Centre) inserting a gene from a Snapdragon flower to create purple tomatos, high in anthocyanin antioxidants. The scientists involved found that mice that were prone to a cancer lived longer when fed with this fruit and hope for similar beneficial anti-cancer effects in our own species. Having said that, the evidence for a protective effect of antioxidants in 'super foods' (like Blueberries), although apparently convincing in theory, is not good. It will be interesting to see how this mixture of Super versus Frankenstein food/Nutritional hope versus Science fact pans out.
This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.
