Pavlicev & Wagner may be interesting, but is irrelevant IMHO. That tonsils and ossicles have their ultimate origins in gills may be so but tells us nearly nothing about their evolution and what they were selected for. The female orgasm seems to be a singular human trait, so tracing it back to something shared by all animals is no relevant explanation at all for its existence.

Marie Curie, Clara Immerwahr, and Lise Meitner had to fight misogynic prejudice in university and even my own mother still faced it in industry. Of course all the less successful female students still claim the same, but the pendulum has swung and any discrimination left now clearly points in the opposite direction as Breda & Hillion demonstrate in one more current example.

When I looked into it more than thirty years ago, storing 1 kWh of electricity in lead acid batteries cost at least 1 DM (due to the limited number of cycles). According to de Oliveira e Silva & Hendrick it has become slightly cheaper but only at the rate of inflation so the price now is a nominally identical 0.5 €/kWh. Regardless of the price and value of electricity this only makes sense Read the rest of this entry »

There are many studies on signalling and costly signalling is, of course, costly and thus hard to fake. But this one by Jordan et al. has to be one of the first to inquire whether the signaler is indeed more trustworthy. I’m gratified to find this bias confirmed by fact.

I have to endure enough junk as it is and I’d never want to read non peer reviewed publications if I can avoid it. That said Balietti et al. point out one of the downsides of the current review process and add one more voice to the choir looking for improvements.

That perceived time can influence consciously observable effects like tiredness after a several minutes jog or ability to hold one’s breath is unsurprising. Park et al. show it to influence a purely physiological process of which we’re unaware and for which we have no sensation. To me at least this comes as a surprise, even more so as the effect seems to be large and consistent.

The main studies on heritability and inheritance were done before the discovery of DNA and genes and they still stand. They are not invalidated by the search for a genetic base of most traits so far drawing up blanks. So Beauchamp’s non-result of statistical significance born from huge numbers alone does not Read the rest of this entry »

Fashionable hypotheses conforming to the prejudices of New Age psycho-babble have an easy ride into the most prestigious journals. It is a refreshing change to see Gerber et al. putting them to the test for once.

Education leads to brain tumor – what a feast Khanolkar et al. have served up to the yellow press. Of course it’s only an observational study and the relative risk of only 1.2 is generally dismissed by serious science, but who cares. In the primary article, not the yellow press rehashes, higher education also boils down to money and socio-economic status and right at the end we find the true explanation: Read the rest of this entry »
