For many of us, there are few creatures more nefarious and loathsome as leeches. But do these parasites deserve their bad reputation as mindless bloodsuckers? Dr. Mark Siddall a.k.a. "The Leech Guy," exposes our many misconceptions of these carnivorous worms and details his on-going research at the American Museum of Natural History into each species' unique cocktail of anti-clotting blood poisons.

It's crunch time for the 'balloonatics' at Macy's Parade Studio. The balloons themselves, which are designed and fabricated in a warehouse in New Jersey, are getting their final checkup before the Macy's Thanksgiving Day Parade. John Piper and Jim Artle take us around the studio and spill the secrets of inflation, explain how to calculate whether your balloon will float, and explain why the balloons look better after a little time in the sun.

The idea of mining Mars, the moon, or an asteroid for its mineral or water resources isn't far-fetched. NASA, the ESA, and several commercial enterprises already have missions in various stages of planning - all to test technologies and probe off-planet terrain for resource extraction. But before you go and land your finely-tuned space drill on an asteroid and suck out the water and carbon, you need to test it out here on earth. And before you do that, you need something to stand in for the rocks and soil of these interplanetary bodies. Using existing data from previous missions, a pinch of geology and chemistry, and and whole lot of jerry-rigged pressure cookers, researchers at Deep Space Industries are cooking up these simulants by the bucket full.
