Tales from the ArXiv: A Population with Two Genders

The English language has reared its ugly head again.

In the paper Constrained evolution algebras and dynamical systems of a bisexual population, the authors actually mean a population with two genders (as one can see from the abstract). This is one of those cases where the direct translation of their desired word into English happens to have a very different meaning.

Three Fascinating Articles

I just read three fascinating articles on CNN.com.

The first one discusses tweeting directly using one's brain to form the letters.

The second discusses differences between men and women with respect to sexual orientation being continuous versus discrete. (There are other things in the article too, but this is what I found most interesting.) Apparently, a bunch of studies are suggesting that it seems to be much more of a continuum in women than in men (and also perhaps that it is more common for a woman to experience a change in location over time).

The third discusses the new Star Trek film. (If you haven't gotten the allusion yet, let's just say that this article is fascinating in a somewhat different manner than the other two.)
