A rooftop farm in Brooklyn grows vegetables and doubles as a green roof, insulating the warehouse below. Green roofs save money on cooling and heating costs and also retain water, reducing the load on sewer systems. Annie Novak, head farmer and co-founder of Eagle Street Rooftop Farm gives us a tour.

Cilia--the little hairs that propel a paramecium--flap spontaneously, and will synchronize their movements with neighboring cilia. But exactly why they do this has been hard to pinpoint because cilia are complicated structures. So researchers fabricated knockoffs, with fewer components, to see if they could figure out what drives the waving.

Just Bulbs, on New York City's Upper East Side, sells just bulbs. There are 36,000 different kinds of lightbulbs in the store, says owner David Brooks. And although customers regularly rail about how compact fluorescent bulbs are ugly, Brooks argues that they've been unfairly maligned. They come in six color temperatures and a wide variety of shapes and sizes.

Malcolm Beck was farming organically in the 1950s, and that's how he got into compost. What started out as a little manure pile on his farm became a 40-acre compost-processing business five decades later. Beck sold his company, Garden Ville, but still works there and is constantly experimenting with different fertilizer formulas--from bat guano to earthworm tea.

Humpbacks whales blow bubbles around schools of fish to concentrate them for easier capture. Although this hunting technique, called bubble-net feeding, has been documented for decades, just how whales make the nets wasn't well-understood until now, says biologist David Wiley.

Theoretical physicist and futurist Michio Kaku takes us on a tour of his office, where he writes his bestsellers and records his radio shows. The futuristic 1950s TV show Flash Gordon jump-started his interest in science. Watching it as a kid, Kaku realized that it was the problem-solving scientist, not the chiseled crimefighter Flash, who was really the hero.

About ten years ago, two scientists had a little extra time on board NASA's low gravity aircraft and came up with the idea of popping water balloons. Mechanical engineers Seth Lichter, of Northwestern University, and Mark Weislogel, of Portland State University, use the floating water balls to explain some basic principles of physics.
