Young Innovators: Detecting Land Mines

Landmine

This afternoon, NPR spoke with Marian Bechtel, the 17-year-old inventor of a device that can detect land mines using sound waves. Earlier this year, Bechtel was awarded a fellowship from the Davidson Institute for Talent Development. Her science fair project -"A Stand-off Seismo-Acoustic Method for Humanitarian Demining" – has won her recognition for her innovation from science contests and from the US Army.

Listen to the interview as Marian describes how she discovered this innovative capability to help detect landmines.

Just geeky

The Crow Vending Machine

American Crow

I’m a big fan of crows, they’re all around me in the Pacific Northwest, they’re intelligent and I love seeing them solve puzzles. Most geeks are probably already aware that crows are pretty unique in the animal kingdom known to create tools and use them (if you’re not aware of this, you can see a short snippet of this tool creation in the following video).

Hacker and writer Joshua Klein is fascinated by crows. (Notice the gleam of intelligence in their little black eyes?) After a long amateur study of corvid behavior, he’s come up with an elegant machine that may form a new bond between animal and human.

After watching the video, check out these links if you want more on this vending machine:
-Gizmodo did a review of the device
-A paper written about the concept
-Josh is also seeking support to make this device more readily available, he needs electrical and mechanical engineers to join him and needs a little funding to support it.

2011: The Year in Pee and Poop

Treehugger gives us a recap of the year in innovative solutions to the sanitation issues facing us here on Earth and in space. The slideshow covers systems purifying human pee so astronauts can stay hydrated, to mushrooms that decompose diapers to the DIY rainwater-flushing toilet.

There’s some cool stuff in that presentation, check it out.
