Submission + - Fruit Flies are Better Than You at Calculus

DudeTheMath writes: Cornell University scientists studied how fruit flies respond to flight disturbances (instead of wind gusts, they used carefully controlled magnetic pulses) and found that the flies recover in as little as three wing beats (at 250 per second) by doing some kind of calculus in a little "integrated circuit" of neurons that control the wings directly. The pitch and yaw results are already published, and the roll study is forthcoming. (NYT, partial paywall, autoplay of fly that starts with a car ad.)

Submission + - Home testing for solar roof coverage?

DudeTheMath writes: Here in the Sunshine State (FL), solar should be a no-brainer. However, large oaks that require permits to trim partially shade my roof. I'd like to (inexpensively) "pre-qualify" my roof for effective panel area. Googling for "home solar testing" gets me equipment for checking the efficiency of an existing PV installation.

Do any makers know what I can do on my own in terms of placing a few individual cells and, over a year, measuring and recording their output, so I can get an idea whether solar would be cost-effective for me?
