If you're too young to remember the 1980s, you'll have to take my word for it: We thought we were pretty cool. New Coke, pink Izods, hair metal and The A-Team. We really turned pop culture on its head! (We didn't turn pop culture on its head.)

Of all the trends that seemed fantastically modern back then, few things said "the '80s" more than aerobics and the requisite leg warmers and unitards. The San Francisco band Moon Duo revives this exercise phenomenon — and everything that now seems ludicrous about it — in a new video for its song "Sleepwalker."

An estimated 14.9 percent of U.S. households — 17.9 million in total — "had difficulty" at some point last year getting food because they just didn't have enough money or other resources, the U.S. Department of Agriculture reported this morning.

In 2010, 14.5 percent of households were similarly "food insecure" at some point, USDA says.

Maybe it will help the ratings.

Before we run through the news of the day, let's pause for something spectactular: a new video from NASA's Solar Dynamics Observatory. It shows a "massive filament" eruption on the sun that occurred last Friday. As Britain's The Register says, it is "mind-bogglingly gorgeous."

Just as they did during the Republican National Convention, independent fact checkers spent the first day of the Democratic National Convention listening for claims that don't add up — and found them.

-- FactCheck.org says it heard "a number of dubious or misleading claims" from the Democrats who spoke on stage Tuesday in Charlotte, N.C. Among the problems it found:
