- David discusses cool research that shows telomere shortening activates p53 which suppresses PGC-1alpha and PGC-1beta, linking telomere shortening (with ageing) and mitochondrial dysfunction Evolving Health: Fusing aging theories: Telomere shortening causes mitochondrial dysfunction I have to wonder if this has something to do with these results in the study I discussed here (Ageing per se increases susceptibility to FFA induced insulin resistance in rodents)

- One quote in particular from this article made me angry:
“Government needs to stay out of the way of free enterprise,”Arizona lawmaker Jim Weiers told the East Vally Tribune last month. “Every business has the right to do something as long as it [is] not actually hurting anyone else.”
He suggested parents are the ones ultimately responsible for childhood obesity.
Fast food targeting kids with toys does hurt them, and to say parents per se are responsible for childhood obesity is just absurd. Mr. Weiers needs to start talking to some obesity researchers to fix his narrow minded perspectives: Ban backlash: U.S. politicians to prohibit bans on Happy Meal toys – The Globe and Mail
