Cow flatulence is kind of funny, but it's no joke. Bovine belching and farting are pretty significant sources of methane gas, which makes them not insignificant contributors of the greenhouse gases behind global climate change. Methane is also the main ingredient in natural gas, and as anyone who has watched Mad Max Beyond Thunderdome knows, livestock-produced methane can (in theory) be harnessed to produce large amounts of electricity.

Last fall, Argentina turned that theory into practice. The country's National Institute of Agricultural Technology (INTA) came up with a method of capturing cow-produced methane before it enters the atmosphere through the mouth or intestinal tract, then compressing that gas and using it to make biofuel to generate electricity or even power a car. "A cow emits about 300 liters of methane a day," or 80 gallons, explains INTA technician Ricardo Buelo.

Basically, INTA's contraption starts with a tube inserted through a cow's skin and into the rumen, or the largest of a cow's digestive tracts. The other end of the tube is connected to a backpack that collects the gas, which is then condensed down into usable form. INTA insists that the procedure is painless for the cow.

Fast Company's Ben Schiller, who discovered these plans this week and spoke with INTA's press office, reports that the methane-capturing gas packs are more a proof-of-concept idea rather than a full-bore solution to global warming. But INTA spokesman Pablo Sorondo says he believes they could be used to power a farm or, in a collective, provide electricity to an entire town. Hey, it worked in Mad Max's Bartertown. Peter Weber

Jordan Norwood of the Denver Broncos set a record on Sunday for the longest punt return in Super Bowl history.

Norwood caught the ball and sprinted for 61 yards before being ran down by Mario Addison on the Panthers' 14-yard-line, NBC Sports reports. The new record shatters the previous one made by John Taylor, 45 yards, during Super Bowl XXIII. Catherine Garcia

Carolina Panthers quarterback Cam Newton is known to celebrate first downs and touchdowns by "dabbing," but did you know it was actually Betty White who taught him everything he knows about the dance craze? Okay, that might not be entirely true, but White is certainly taking credit for it in a new CBS Sports video. Watch everyone's favorite golden girl show off her moves in the video below.

Before Super Bowl 50 began, the MVPs from previous years were celebrated during a ceremony at Levi's Stadium.

Former football stars Joe Montana, Joe Namath, Jerry Rice, Steve Young, and Ray Lewis were cheered, but one player wasn't shown the same respect — Patriots quarterback Tom Brady, who instead was booed by the crowd. Watch the video below. Catherine Garcia
