Peristaltic writes: Scientists at the U.S. Department of Agriculture are trying to determine if an unexpected mutation in a popular GM grass, Tifton 85, is responsible for the sudden deaths of a small herd of cattle in Elgin, Texas three weeks ago. The grass has been used for grazing since 1992 without incident, however after a severe drought last year in Texas, the grass started producing cyanide in sufficient quantities to kill a small herd of cattle in Elgin, Texas. Testing has found the cyanide-producing grass in nearby fields as well.

This latest incident once again highlights the debate regarding the benefits vs. the risks of using gmo in agriculture

Submission + - Methods of learning to build electronic circuitry?

Peristaltic writes: I've seen some cool articles in Instructables detailing how to create various electronic gadgets. A couple of these as well as the odd DIY kit have come to life on my kitchen table. While it's satisfying to see the things work after time spent soldering, I would love to be able to take the next step beyond the basics of component functionality, i.e. a resistor does this; a capacitor does that. Forest Mimm's books have been helpful towards this end...but it's time to move forward. Every month or so, I read here on Slashdot a plea for help getting started with, or expanding someone's knowledge of programming. O.k., I'd like to make that plea for help with electronics theory & circuit building. I've found plenty of references on the web, Amazon, etc., but can someone who's already taken this trip outline what has and hasn't worked for them?
