A very much overhyped - but still interesting - piece of science appears in the New Zealand Herald. Many lower forms of life have the ability to extend their lives in a sort of low-activity state, but this particular parasite is impressive: "The genes allow worms in the possum's small intestine to live for up to a year - while the same worms live outside in the soil for only a matter of days if they do not 'switch on' the longevity genes." Similar genes occur in humans, but that certainly doesn't mean the work has any relevance to our health and longevity. From the researcher in charge: "If you are putting money into this, from a commercial angle a lotto ticket would be a better idea." Still, a grant has been provided for further study.
