Grow your own antenna

Dig it: NASA has been using evolutionary algorithms to evolve superior antenna designs. As their web site puts it:

Our approach has been to encode antenna structure into a genome and use a GA to evolve an antenna that best meets the desired antenna performance as defined in a fitness function. Antenna evaluations are performed by first converting a genotype into an antenna structure, and then simulating this antenna using the Numerical Electromagnetic Code (NEC) antenna simulation software.

That tiny, weird-looking antenna above? It uses less power than previous, similar designs, yet allows for a broader array of angles at which it can receive data.

(Thanks to Boing Boing for this one!)
