Why we are addicted to science

This is a question that has neither a quick nor a simple answer. Spontaneously, I would not talk about the challenge but the reward system included. Maybe the addiction question ( and it is indeed an addiction for some people ) can be answered by analogy of a much simpler experiment using the “Candy Crush Saga” app that works extensively with audiovisual rewards. Even time.com is now writing about this app and identifies 9 key issues: Continue reading Why we are addicted to science

Science delusion

It is a bit annoying. If you google for science delusion, you are only referred to Sheldrake. But this is not what I wanted, I was more interested in mad scientists.  Not Frankenstein,  not Moreau not Dr. Faustus not any literary character, some more real life figures. Also not Venter. But here comes something interesting

In 1951, entomologist Jay Traver published in the Proceedings of the Entomological Society of Washington [Traver, J. (1951). Unusual scalp dermatitis in humans caused by the mite, dermatophagoides (Acarina, epidermoptidae). Proceedings of the Entomological Society of Washington, 53(1), 1-25.] her personal experiences with a mite infestation of her scalp that resisted all treatment and was undetectable to anyone other than herself. Traver is recognized as having suffered from Delusory Parasitosis: her paper shows her to be a textbook case of the condition. The Traver paper is unique in the scientific literature in that its conclusions may be based on data that was unconsciously fabricated by the author’s mind.

The author ( Matan Shelomi, Mad Scientist: The Unique Case of a Published Delusion Matan Shelomi, Sci Eng Ethics (2013) 19:381-388) believes that a possible retraction of the 1951 paper raises the issue of discrimination against the mentally ill –  others may consider this as delusionary correctness.

Payback for referees

There is a recent letter at Nature saying

I have discovered a negative correlation between the number of papers that a scientist publishes per year and the number of times that that scientist is willing to accept manuscripts for review  … I therefore suggest that journals should ask senior authors to provide evidence of their contribution to peer review as a condition for considering their manuscripts.

While I agree with the overall observation, Continue reading Payback for referees

A Science career should not be like a Mastermind game

You do an experiment or a clinical study and you are the code braker not knowing the peg positions and colors ( set by a code maker ).

The codebreaker tries to guess the pattern, in both order and color, within twelve (or ten, or eight) turns. Each guess is made by placing a row of code pegs on the decoding board. Once placed, the codemaker provides feedback by placing from zero to four key pegs in the small holes of the row with the guess. Continue reading A Science career should not be like a Mastermind game

Value replicability not journal impact

There is an excellent comment on research misconduct at the brand new Pubmed Commons site by Dorothy Bishop:


Instead of valuing papers in top journals, we should be valuing research replicability. This would entail a massive change in our culture, but a start has already been made in my discipline of psychology (see http://www.nature.com). Continue reading Value replicability not journal impact

On risk taking

Here is a recent interview transcript of Bruce Beutler

JCI: Would you advise any of your trainees to have the same drive and motivation you did to go after one singular problem with the same kind of tenacity that you had?
Beutler: I was often told by people, including by my father, that I was putting all of my eggs in one basket. But I must say in retrospect, if we hadn’t been focused and committed to one problem, we probably wouldn’t have got there. It was risky but I would counsel people to undertake high-risk projects and do them serially, rather than to work in parallel with a number of low-risk projects.

Should we boycott top science journals?

Maybe it is easier to answer that question if you are a noble winner. The Guardian is reporting two days ago

Leading academic journals are distorting the scientific process and represent a “tyranny” that must be broken, according to a Nobel prize winner who has declared a boycott on the publications…
Randy Schekman, a US biologist who won the Nobel prize in physiology or medicine this year and receives his prize in Stockholm on Tuesday, said his lab would no longer send research papers to the top-tier journals, Nature, Cell and Science.

With the large distribution factor of the internet, I think there is nothing to loose by sending a paper to PLoS or some of the BMC journals. Quality will survive, yea, yea.

Reference values should be based on reference populations and not on politics

For a long time this has been a general rule. Just take the mean and substract two standard deviations and you get some useful reference values. Or whatever algorithm you like. This changed considerably where commercial or any other personal interests come into play. The cholesterin discussion settled only by studies showing that people with a history of cardiovascular disease may derive benefit from statins irrespective of their cholesterol levels.
I see some analogy in the vitamin D field. There is a German dermatologist who believes that 60% of all Germans are vitamin D deficient (the comments following the interview highlight this as an epiphany “totale Erleuchtung”). And a more recent paper showed that “89.9%” of all healthy newborns being insufficient. Really looks like a mix-up of some basic concepts in clinical medicine, yea, yea.

Negative metrics is not such a bad idea

Nature recently raised an extremely important point

Research metrics are ambiguous — a paper may be cited for positive or negative reasons. Funding agencies and universities focus on positive impact in evaluating research, which increasingly includes alternative metrics. We think that researchers can generate a more complete account of their impact by including seemingly negative indicators — such as confrontations with important people or legal action — as well as those that seem positive.

Yea, yea.

Ich habe doch nichts zu verbergen !???

Wie oft habe ich den Satz in den letzten Wochen schon gehört… und er wird durch die häufige Wiederholung nicht richtiger. Denn natürlich habe ich etwas zu verbergen, wie die meisten Menschen, ich bin sogar vom Staat zum Arztgeheimnis verpflichtet worden.
Hier kommt jedenfalls ein sehr detailliertes Video für alle “die nichts zu verbergen haben”.

Bad news are good news

e! Science News reports a new study in EPJ Data Science by Marcel Salathé showing that anti-vaccination sentiments spread more easily than pro-vaccination sentiments.

We find that the effects of neighborhood size and exposure intensity are qualitatively very different depending on the type of sentiment. Generally, we find that larger numbers of opinionated neighbors inhibit the expression of sentiments. We also find that exposure to negative sentiment is contagious

Read the full paper for the tricky design – at least the results fully underpin daily life experience. It’s certainly much easier to do Twitter than Facebook studies on the other hand these rather short messages are certainly not the main channel of many great “opinionated” people.

The best vitamin D paper in 2012

The turn of the year may not only indicate many new chances but also allow a higher standpoint. IMHO the best paper in the vitamin field was published by Rousseau Gama in the BMJ 2012;345 :e5706.

We measured serum C reactive protein and 25-hydroxyvitamin D concentrations before and two days after elective knee or hip surgery in 30 patients. After surgery the mean serum concentration of C reactive protein increased (5.0 (SD 5.5) v 116.0 (81.2) mg/L; P <0.0001), whereas serum 25-hydroxyvitamin D decreased (56.2 (30.3) v 46.0 (27.6) nmol/L; P <0.0006).

The reasons are not fully clear but the results are consistent with two other studies reporting a fall in serum 25-hydroxyvitamin D concentration during a systemic inflammatory response. So, it looks like 1 simple study will make 1000 other studies useless. That seems to be the beauty of science… although I do not understand how that related to a serum half-life of two weeks?
So far I argued that vitamin D is always a lifestyle proxy e.g. pubmed/22698792) but there maybe also biological reasons.
BTW I would also have a candidate for the worst vitamin D paper, just in case, ….
