Marshall has obvious implications for the continual attempts to sever even one- and two-year-olds from their mothers and offload them to state run institutions for most of the day.
The more we come to know about mother’s milk, as in Gura, the more valuable it gets and less easy to substitute.

Perry et al. offer another proof, that the characteristic physiognomy of African pygmies is adaptive and highly selected for. One question I don’t know the answer to and haven’t seen discussed so far, is how much the climate and environment on the island of Flores is similar to Africa’s tropical rain forest and induces the same selection pressure.

Although the reaction itself is exothermic, ammonia synthesis through the Haber-Bosch-process consumes huge amounts of energy worldwide and the generation of its hydrogen feedstock even more so. Licht et al. have found a way to combine the two and use the enthalpy of the synthesis to partially offset that of splitting water. Contrary to steam reformation the process itself does not generate carbon dioxide (more…)

Loads of tabloid stuff this fortnight but little of substance. Yang et al. finally solve the riddle, why slim and fat women always go to the loo together. Shame the model breaks down for old men.
Being sensitised to current carbon-dioxide scams I was skeptical about Graciani et al.’s catalytic methanol production. (more…)

Sovacool’s stance is not surprising once you realize that he touts his own commercial interest here. His solution of solving technical problems by massive, state sponsored, and mandatory reeducation has been tried for over forty years. Not only was it voted down by overwhelming public opposition, (more…)

According to Ochiai et al. ignoring all health warnings and spurning all Government mandated precautions may not be conducive to perfect health in the aftermath of a nuclear accident. Bet you knew that already. The more relevant part seems to be the generally good state of health in observed fauna in spite of their less than perfect blood values.

Teaching how to read used to be the job of primary and high schools and undergraduates were expected to pick up the subtleties of primary research reporting through learning on the job. Formal niceties used to be remarked on by the lecturer while discussing the content of papers. Looking at the current batch of first years, van Lacum et al. may well have a point. What they fail to say is that, given limited time and already full schedules, (more…)

From Bohannon I finally learn what being a perpetual student is really worth. Bus fares and reduced entry are peanuts when my library shells out $ 2.00 for every article I read online, that’s $ 50.– for a typical blog entry every week. Does the taxpayer get any value back for his money? (more…)
Apologies for tardiness and skipping a week.

For Gillespie et al.’s hypothesis to make sense, menopause would have to be an exceedingly young phenomenon, only appearing after the establishment of sedentism and agriculture. This means we’d have to expect at least some residual hunter-gatherer societies not to possess it. (more…)

Although the Solutréen hypothesis is unanimously condemned by the archaeological mainstream, John J. Shea is not someone whose opinion can be easily dismissed out of hand. As Stanford & Bradley point out in their reply to O’Brien et al., what counts is not the average state of ice over thousands of years, but a stable shelf for less than a century suffices (more…)
