Patternicity: Finding Meaningful Patterns in Meaningless Noise
In a September paper in the Proceedings of the Royal Society B, “The Evolution of Superstitious and Superstition-like Behaviour,” Harvard University biologist Kevin R. Foster and University of Helsinki biologist Hanna Kokko test my theory through evolutionary modeling and demonstrate that whenever the cost of believing a false pattern is real is less than the cost of not believing a real pattern, natural selection will favor patternicity.

Researchers identify a potentially universal mechanism of aging
Has universal ageing mechanism been found?
"We then began wondering what would happen if we put more of the sirtuin back into the mice," says Oberdoerffer. "Our hypothesis was that with more sirtuins, DNA repair would be more efficient, and the mouse would maintain a youthful pattern gene expression into old age." - That's precisely what happened. Using a mouse genetically altered to model lymphoma, Oberdoerffer administered extra copies of the sirtuin gene, or fed them the sirtuin activator resveratrol, which in turn extended their mean lifespan by 24 to 46 percent. -- "According to this specific mechanism, while DNA damage exacerbates aging, the actual cause is not the DNA damage itself but the lack of gene regulation that results," says Oberdoerffer. "Lots of research has shown that this particular process of regulating gene activity, otherwise known as epigenetics, can be reversed—unlike actual mutations in DNA. We see here, through a proof-of-principal demonstration, that elements of aging can be reversed."
