is a book that I am currently reading. There is also a brief German/English account how this sentence came into life. What the hell did you expect when reading the title??

Something like “winners don’t punish”? A smart letter in this week’s Nature with the 3 options of Cooperation(C) – Defection (D) and Punishment (P)?

"nice people"
player 1: C C C C
player 2: C C C C top payoff!
"punish and perish"
player 1: C P P P P
player 2: C D D D D extremely bad!
"turning the other cheek"
player 1: C C C C C
player 2: D D C C C payoff still positive!

we should have known this earlier…

As filaggrin – one of our best atopy genes – is vitamin D dependent, I tried to find out more about epidermal differentiation. The plot here summarizes an earlier review:

There seems to be a clear calcium gradient with the expression of differentiation specific marker in the single strata. So there is some good chance that filaggrin effects may be modified by external vitamin D supply.

For everybody who wants to follow up the most recent discussion about allergy promoting effects of vitamin D here is a short summary. The Harvard group basically wrote three articles that were immediately contradicted. The comment on the first article in JACI was by a NIH researcher (Show me more…)

The central limit theorem states that a sum of independent identically distributed random variables (lets say allele counts in genomewide association scans) of finite variance will be approximately normally distributed. Unfortunately the maximum of the distribution will not reflect the true value … or did I get it wrong?

I am currently playing with MACH and SNPMStat to impute marker based on public datasets. I do not have any opinion about the usefulness of this approach – largely due to the fact that ~10% of my allele coding is different to the public hapmap data. (Show me more…)

The appendix of Frey includes a list of errors based on evolutionary psychology (EP) – some acquired during development of our species, some acquired during individual ontogenesis. It is certainly the best what I have read since the famous study biases (Show me more…)
