Two “science” links in one week?

Blame Karan for this one.

Within a few years we could be using genetically engineered plants to warn of landmines:

The genetically modified weed has been coded to change color when its roots come in contact with nitrogen-dioxide (NO2) evaporating from explosives buried in soil.

Within three to six weeks from being sowed over land mine infested areas the small plant, order a Thale Cress, will turn a warning red whenever close to a land mine.

According to data compiled by Aresa, more than 100 million land mines have been spread out in 45 countries, hidden killers that often remain for years after a conflict is over.

Oestergaard said the problem of sowing the seeds in a potential land mine could be overcome by clearing strips through a field by conventional methods or by using crop planes.

Currently land mines are mostly removed by putting a stick into the ground to locate the mine, then removing it and detonating it. Dogs and metal detectors are also often used.

    That is a fantastic innovation! And utterly environmentally friendly. How do they propose sowing the seed?

    *blush* thanks guys.

    As for sowing the seeds, the chap from Aresa Biodetection said:
    “…clearing strips through a field by conventional methods or by using crop planes.”

    Not sure about the conventional methods, sounds dangerous. I’m with crop planes.
