    My worst review said that my paper was technically sound but my entire specialty was a “cottage industry” generating computational models with no real-world relevance and therefore the paper should be rejected. The editor offered the opportunity to rebut but what could I say to something like that?

    (The reviewer still lives, as far as I know.)

    On the plus side, this meant that I was rejected by PNAS but then published in BJ.

    Species with internal fertilization tend to have females care for the young because the male is the one who can leave first. He can maximize his reproductive success by searching for other females while the female is left with the choice between putting a lot more time and energy into caring for the offspring or leaving them to die.

    Species with external fertilization usually have the opposite dynamic. The female lays unfertilized eggs and then leaves. The male is the one stuck caring for them because they would die otherwise. However, the males of some species have evolved to be too clever for this:

    Among the maternal mouthbrooding cichlids, it is quite common … for the male to fertilise the eggs only once they are in the female’s mouth.











  • Those numbers aren’t right.

    First, the total-gun-death numbers are not population-adjusted and therefore useless without additional context. The same article does have the population-adjusted numbers and the USA is, predictably, not in the top ten.

    Second, once the numbers are adjusted for population, there are some very strange results. For example, apparently Iraq actually has slightly fewer gun deaths per capita than the USA. Nigeria, the country where Boko Haram is based, has four times fewer gun deaths per capita than the USA?! Clearly the gun-death numbers correspond more to how well records are kept in a country than they do to the actual numbers of gun deaths.

    Oh, and those gun death numbers include suicides, not just murders. Most gun deaths in the USA are suicides. A suicide is technically a gun death, but not usually the sort that people have in mind when discussing a school shooting.
