Peptide YY and appetite
Just about three months ago we came, briefly, across the peptide called PYY (peptide YY), which has been known, for a few years, to suppress appetite. It has also been known that obese people secrete less PYY than non-obese people. On the other hand,...

Rings and ideals
It's time to do some more algebraic number theory again. For a refresher on what's gone on so far, check here.In the last installment, way back in June, I introduced rings of algebraic integers, which are the main object of study in algebraic number...

Digital storage technology
In 1983 personal computers (there were no laptop computers in those days) usually did not come with hard disks as standard equipment, but the disks could be bought as an add-on. I bought a 10 MB (megabyte) disk for about $200 back then. In 1994 hard...
