Ripeness Sticker Coming to Supermarket Fruit

Adam Weiss writes "A biosystems engineering professor has just announced a "ripeness sticker" for fruit. According to this AP article, grocers throw out thousands of bushels of fruit a year because it ripens too fast (1 bushel is about 9 U.S. gallons). Mark Riley's RediRipe stickers turn from white to blue as fruit ripens. The stickers react with ethylene gas, a chemical which is released as fruit or vegetables ripen. However the article says "there are still bugs to be worked out: The stickers do not change color to reflect an overripe or rotten piece of fruit. Also, not all fruit produces enough ethylene to be detected by the sticker.""

    Haven't researched it, but I very much doubt that the German "liter" was derived from the French "litre" via American spelling.

    The point was that just because someone writes it liter, one cannot assume (as the AC did) that the writer is American.

    Ah, but the Slashdot editors reside in Michigan, no? And... correct me if I'm wrong... but that's in the US? ;-)

    Besides, news for nerds, we all ought to be capable of doing that conversion... I can tell you how many liters per gallon, why can't you tell me how many gallons per liter?

    "Rightwing" might be a bit of a misnomer though. It's not like they are way, way right. Also, given that this is a fairly US centric site it could probably be seen as a center/left paper.

    I wouldn't call running across the field with a inflated device that is does not even resemble a spherical shape football. It seems neither feet (except for the running of course) nor balls are involved.

    You are missing Aussie Rules Football and Gaelic Football as well. Heck we could go on for ever.
    I always have a problem when they compare things to football fields in documentaries. Then again, it's better then some other examples :
