46 percent

A study of 18- to 24-year-olds in the U.K. found that 46 percent reported losing sleep over finances. And they don’t even have to deal with the student debt and health care and pharmaceutical costs that we do! [The Guardian]


78 percent

Probability that Donald Trump will win the Feb. 20 South Carolina GOP primary, according to our polls-plus forecast, up from 56 percent a week ago. Our polls-only forecast gives Trump an 87 percent chance. [FiveThirtyEight]


85 percent

Recycling mobile phones is a big business, and Apple has found a way to extract even more resources from recycled handheld devices.

85 points

Marco Rubio secured the endorsement of South Carolina Gov. Nikki Haley, and with it an additional 10 points in our endorsement tracker.

310 emails per year

The service Unroll.me essentially serves as a bouncer for inboxes, allowing people to have some control over what kinds of email they receive. This gives them a front-row seat to the email habits of many of America’s spammers and subscription services. For instance, Groupon sent users about 388 emails on average last year, the highest of any sender Unroll.me tracked. Even Facebook was in on the email game: On average users got 310 emails from Facebook. [Unroll.me]


$864

857 delegates

Gaming out this election a little further, if Bernie Sanders wants to win the Democratic nomination, he has to do well in the contests on March 8 (when Michigan and Mississippi vote) and March 15 (when Missouri, North Carolina, Florida, Ohio and Illinois do). Over those two days, 20 percent of the total number of pledge delegates are allocated, 857 to be exact. [FiveThirtyEight]
