Reading this blog will improve your academic skills

Aren’t hat good news being published by Science this week?

Process-specific training can improve performance on untrained tasks, but the magnitude of gain is variable and often there is no transfer at all. We demonstrate transfer to a 3-back test of working memory after 5 weeks of training in updating. The transfer effect was based on a joint training-related activity increase for the criterion (letter memory) and transfer tasks in a striatal region that also was recruited pretraining.

German Science blogging

The German blogosphere is now being mapped but with a few exceptions German science blogging doesn’ play a major role (in contrast to knitting that shows a large cluster Continue reading German Science blogging

Placebo for placebo

or “Do placebo responders exist?” is a remarkable new review by researcher from the Harvard Medical School. I always wondered about the sheer size of the placebo effect (and its perception as nuisance parameter). The authors simply ask the question

… this paper also examines the evidence for the existence of a consistent placebo responder, i.e. a person who responds to placebo in one situation will respond in another condition or using a different type of placebo ritual….

Suggestibility is a human trait, yea, yea.

DNA for DNA

It might be fun to read here on a genetics board about DNA (Direct Note Access) which is a technology implemented in Melodyne that can extract notes from polyphonic music.
So far, it does not use a library of musical instruments according Peter Neubäcker, head of development, in an interview published in c’t 8/2008, p 34. It separates “musical content” defined by periodicity, similar overtones and meaningful musical distance like halftones. Although that’s something bioinformatics is trying for some while for DNA (desoxyribonucleic acid), I wonder if the decomposition concept in DNA would works also for DNA, yea, yea.

Ivan Hajek – there is no better accordion player

This morning when leaving the Munich underground, I could hear Ivan – the best accordion player in the world. There are numerous videos at YouTube, so listen if you like Continue reading Ivan Hajek – there is no better accordion player

Our lives are unrepeatable experiments lacking a control

a prosaic quotation from the recent Nature correspondence section that highlights why genetics has been leading us into nowhere.

Our lives are unrepeatble experiments lacking a control. Myriad external factors interact with genetic and epigenetic factors and with chance to determine whether we are well or ill, smart or dull, successes or failures.

Yea, yea.

If pigs could fly

is a book that I am currently reading. There is also a brief German/English account how this sentence came into life. What 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…

Central limit theorem

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?

Why blog writing is something different from writing a paper

This may be obvious, at least if you have read Daniel Gilbert

In 2002, Jane Ebert and I discovered that people are generally happier with decisions when they can’t undo them. When subjects in our experiments were able to undo their decisions they tended to consider both the positive and negative features of the decisions they had made, but when they couldn’t undo their decisions they tended to concentrate on the good features and ignore the bad.

When reading my own writings a second time, I always discover typing errors, crude sentences, and other poor habits – blogs as snapshots of less happier minds?
