Why do women suffer more migraines than men?

"Boys experience more migraine than girls before puberty, then the equation changes, with girls and women bearing the brunt of migraine until after menopause. The disorder then eases for most women.

For this reason, most experts believe that women’s fluctuating hormones are a major influence, especially when estrogen falls around the time a women has her menstrual period. Most attacks occur several days before or after menstruation.

Green thinks estrogen withdrawal is a major trigger."...

While we bite fingernails... A fairly important puzzle mathematicians have been studying for at least 25 years is closer to being solved, thanks in part to Australian science fiction writer Greg Egan. Egan has provided an upper-bound solution to the super-permutation problem, to match the lower-bound posted anonymously online by someone even more mysterious than Greg! One thing that this solves – or refutes - at once is the hypothesis about Greg Egan (author of “Permutation City)… that I set up a postal box when I was in Perth in 1985 and… well, now it is clear that the lower bound of people who could possibly imitate or concoct Greg Egan is at least two, since – while I do understand this fascinating article – I’m not plausible to have actually done the original math!

For a recent SF novel with some interesting overlaps with this reality, see Matt Ginsberg’s “The Factor Man.”

Physicists implement a version of Maxwell's famous thought experiment for reducing entropy - Reduced entropy in a three-dimensional lattice of super-cooled, laser-trapped atoms could help speed progress toward creating quantum computers. A team of researchers at Penn State can rearrange a randomly distributed array of atoms into neatly organized blocks, thus performing the function of a "Maxwell's demon"—a thought experiment from the 1870s that challenged the second law of thermodynamics.
