This week’s roundup includes a bit of the depressing (the U.S. has very little social mobility), a bit of the uplifting (math can lead to love), and the trivial but cool (a chart of our music tastes by decade).

Using numbers to find love: Data nerds are inherently attractive people, but this week came another story of someone taking it up a notch in the online dating world. Mathematician Chris McKinley used math, some truly impressive coding skills, and a willingness to go on lots of first dates to up his chances of finding Ms. Right on OKCupid. The best part? It worked.

What new domain names are going to look like: Chances are that many of the websites you visit end in one of a few ways: .com, .org, .net, and .gov, for example. But come Feb. 4, addresses are going to become much more diverse, as the internet adds 1,000 new website address suffixes, technically known as gTLDs. Many new gTLDs are more descriptive than current choices; the new roster includes .tunes and .baby. Quartz helpfully mapped out the new names this week.

Economic mobility in the U.S. isn't getting worse: A new study from researchers at Harvard University and the University of California-Berkeley explained that mobility isn't getting worse, contrary to popular belief. It would be good news, except for one other key finding: mobility has for decades simply held steady at very low levels. (Bonus finding: the great state of Iowa is the most economically mobile state in the nation.)

Google maps the music universe: Google has been watching what sort of music users have been listening to on its Google Play service, and using that data has charted what we're listening to, in some cases decades after the songs were released. The result isn't so much a map of the music scene over time as a map of what kind of music has phenomenal staying power.

Music that makes you dumb: Today's final link is a throwback to a study you might want to keep in mind while you sort through Google's music. Liking certain artists, it seems, could mean you're kind of dim. At least, that's what one researcher, Virgil Griffith, found when he matched up people's music tastes with their alma maters' average SAT scores, as reported by College Board. No, there's no causation; there is, however, another reason to make fun of Nickelback (And for those who are curious, Griffith did it for books, too.)
