Who doesn't love a good Rube Goldberg machine? Purdue University has been hosting a contest every year since 1983, and nationally since 1989, to see which collegiate team can build the best Goldberg-style contraption, defined as accomplishing a simple task in no fewer than 20 steps. This year, the task was zipping a zipper, and the home team won — Purdue's Rube Goldberg squad managed to contrive about 75 steps to complete the easiest of objectives.
Kudos to Jimmy Kimmel for having the team bring their Rube Goldberg machine on his show. The dumpster-diving engineers who designed and built it are as delightful as you'd expect, and their machine really is quite impressive — though if I were Guillermo, I'd have been pretty nervous near the end, too. There's probably a reason this is the first entry in more than 30 years to incorporate a human participant. --Peter Weber
Super Bowl 50 started off with a bang, as Lady Gaga sang a beautiful rendition of the National Anthem. In an earlier interview with the NFL Network, the pop star said performing at the Super Bowl was an "honor" and "a total dream come true." Catherine Garcia

The United Nations Security Council condemned North Korea on Sunday for defying international warnings in launching a long-range rocket that many believe is a cover for a test of a ballistic missile that could reach the United States mainland.
All 15 Security Council members approved a statement at an emergency meeting emphasizing that using ballistic missile technology violates four resolutions, The Associated Press reports. The group also vowed to adopt a new resolution soon with "significant" sanctions for North Korea. Julie Kliegman
In a Monmouth University poll released Sunday, Donald Trump leads the Republican field with 30 percent of the support from likely New Hampshire primary voters. Marco Rubio and Jeb Bush are tied for 13 percent, with Ted Cruz notching 12 percent.
On the Democratic side, Bernie Sanders leads Hillary Clinton, 52 percent to 42 percent.
The poll's margin of error is 4.4 percentage points. On Tuesday, New Hampshire will be the second state to vote in the primaries. Julie Kliegman
Bernie Sanders distanced himself Sunday from "Berniebros," a wide-ranging term that some have used to describe sexist supporters of the Vermont senator.
"It's disgusting," he said on CNN's State of the Union. "We don't want that crap. Anybody who is supporting me and doing sexist things, we don't want them. I don't want them. That's not what this campaign is about."
