Resveratrol May Not Extend Life | The Scientist

Resveratrol May Not Extend Life | The Scientist.

Hector et al. recently published a meta-analysis of the overall effects of resveratrol (link below).� Overall, resveratrol it seems to decrease risk of death, but the strength of the effects are highly variable depending upon species. It seems to extend lifespan reliably in yeast and worms, but not so reliably in other critters. Too bad! We all love our red wine… we’ll have to await the results of human trials… Who’s with me??

Goodmorning, sunburn… the earth says hello?

Researchers from North Carolina have shown a link between the time of day of sun exposure and the probability of getting skin cancer… It turns out that our own circadian clock affects how well we can repair UV damage to DNA and other cellular components, and the morning is when our structural repair capacity is at its best. Read a summary written up for F1000, or get the primary research article from the Proceedings of the National Academy of Sciences.
