[semi OT, FH] Mine detecting plants

G'day,

Just found this in my "Nature" journal articles this morning. The
question is who would volunteer to do the watering?!

	
Plants to uncover landmines
Genetically engineered plants turn red when growing over a mine.

A genetically engineered plant that detects landmines in soil by
changing colour could prevent thousands of deaths and injuries by
signalling where explosives are concealed....
