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, 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.

ok firstly god daisy your blog is beautiful. I normally surf the web using my laptop and the colours come out very different on there (hence i thought for a long time my blog looked alright!)
But this is gorge!
Secondly… crop dusting great.. i was thinking the same thing. Sounds good huh. Better than the poke the ground with a stick methos methinks! (poor doggies!)

Where you go science follows…pink daisies identify potential land mines?

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

And I agree with Fluffy- your blog is beautiful, amongst other excellent qualities.

They poke dogs into the ground? How cruel!

*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.

Jolly good thing I read your entire article thoroughly what what! Do you go huntin’? Pass the cigars old chap.
I read and re-read twice looking for that info, plus I read the original, and I didn’t find it. Damn my speed-reading!
