Over the past four years Dr Hanano, who works in the commission’s molecular-biology department, and his colleagues have developed a way to use the stones (or pits) of dates, a waste product of the fruit-packing industry, to clean up dioxins, a particularly nasty and persistent type of organic pollutant that can lead to reproductive and developmental problems, damage the immune system, and even cause cancer.
