Encyclopedia Brown and the Case of the Missing Lake: Scientists are on the hunt for a five-acre lake in the Andes (or not in the Andes, perhaps?) that's gone missing. The lake was last seen in March, but in May scientists only found a 100-foot crater with sheets of ice that originally used to float on the lake's surface. Some think the water from the lake may have leaked through cracks in the bottom of the lake into underground fissures, but they don't know where the fissures would have come from. My theory: David Copperfield. Just a hunch.
Cow Dung alternative energy, reinventing the (intelligent) wheel, and how to walk on walls all after the jump!
More Fun Alternative Energy Sources: While the rest of the world works on generating energy from such drab sources like the sun and wind, some scientists are creating more innovative ways to power our lives. A few examples:
Cow Dung: Scientists are researching how to purify the methane gas present in cow excrement to turn feces into a feasible energy source. The theory simply proves that BS even has uses beyond writing papers.
Fruit: It turns out fuel made from fructose is actually better than fuel from ethanol.
Your Workout Routine: A gym in Hong Kong is placing generators in some of its machines, harnessing the power created when people worked out to power the fluorescent lights. It's only a little bit like being in a hamster wheel.
Eat off the floor!: The 5-second rule, that old standby of nutrition, is off by at least five times, according to student researchers at Connecticut College. They tested a variety of foods to see how long it took for bacteria to infiltrate and found that wet foods took 30 seconds to attract bacteria, with dry foods taking even longer. Skittles are apparently a magical repellent, since it took at least five minutes for bacteria to show a bacterial presence. I'm still not sure this justifies me munching on the stray ones I just found under my bed, though.
Geckos do more than just hawk car insurance: By imitating the nano- and micro-scale structures on gecko's feet, scientists have created an adhesive that's strong enough to allow robots to walk on walls. The "gecko tape", which could also be used to create gloves for astronauts, is reusable because it doesn't use glues. Instead, the microtubes conform to the molecular gaps on a surface. I don't know about the rest of you, but I'm going to hold off for a bite from a radioactive spider for my wall-climbing abilities.
