Cooking a whole hog over a pit takes a long time — about 12 hours, give or take – and it is strenuous work.

James Beard Award winner Rodney Scott, 49, should know. He's been barbecuing whole hogs for decades. Over the years, he's learned how to keep himself going through the marathon working hours.

"While I'm cooking I would be listening to tunes, and that kind of helped me get through the long, 12-hour cooks."

The reason it's so hard to kill a mosquito is that they move really well.

Scientists are trying to build a robot with that kind of agility. And these tiny but mighty flying robots could be used in life-and-death situations, such as finding people in a collapsed building.

Kevin Chen says he spends "a lot of time looking at the flapping-wing physics, that is understanding how an insect can flap their wings and generate lift and drag forces."
