Science in Seconds - Bomb Sensing Plants

Science in Seconds Know Everything RUMOURS - Bomb Sensing Plants Torah Kachur: It is estimated that there are up to 25,000 casualties every year from land mines. 90 percent of those casualties are civilians who lose life and limb to the necessary weapons of war. Croatia, Afghanistan, Angola, Rwanda. Countries torn apart by fierce wars in the past decade are still losing lives to the conflict. There are an estimated 100 million active land mines all across the globe. But science to the rescue. As usual. New technologies in land mine detection are decreasing the time and money it takes to remove these hidden terrors. Anti-personnel mines are the most difficult to find, as they're often small and made of plastic, so they can't be detected with simple metal detectors. Several researchers are working towards plants, like tobacco, that can detect explosive chemicals, like TNT or RDX, and start to fluoresce green so that we can scan for them by air or ground. A new plant, called Red Detect from the Danish company Aresa Biodetection, changes color when unexploded ordinances are detected. The plant, Arabidopsis thaliana, or thale cress, has been genetically engineered to turn red when it detects nitrogen dioxide that evaporates from buried explosives. All it takes for detection is to seed these genetically engineered crops across a field that has land mines, and in five to six weeks the plants will have grown enough for the red color to be clearly visible by bomb removal squads. It's efficient, effective and, most of all, brilliant. Humanitarian science at its best. Which is great. Except, of course, countries like the US, China and Russia refuse to sign a land mine treaty. So science can save the day and remove them, but science can't stop the superpowers of the world who are just putting them right back.
