    Common Weedkiller Turns Male Frogs Into Females
    by Maggie Fox

    WASHINGTON - Atrazine, one of the most commonly used and controversial weedkillers, can turn male frogs into females, researchers reported on Monday.

    File photo shows a frog at the Besancon Natural History Museum. One of the most common weed-killers in the world, atrazine, causes chemical castration in frogs and could be killing off amphibian populations worldwide, a study published showed.
    (AFP/File/Jeff Pachoud) The experiment is the first to show such complete effects of atrazine, which had been known to disrupt hormones and which is one of the chief suspects in the decline of amphibians such as frogs around the world.

    "Atrazine-exposed males were both demasculinized (chemically castrated) and completely feminized as adults," Tyrone Hayes of the University of California Berkeley and colleagues wrote in the Proceedings of the National Academy of Sciences.

    The chemical had been shown to disrupt development and make frogs develop both male and female features -- termed hermaphroditism. This study of 40 male frogs shows the process can go even further, Hayes said.

    "Before, we knew we got fewer males than we should have, and we got hermaphrodites. Now, we have clearly shown that many of these animals are sex-reversed males," Hayes said in a statement.

    "Atrazine has caused a hormonal imbalance that has made them develop into the wrong sex, in terms of their genetic constitution."

    Brother Ankhur ... you are including a link with the article, that is good, but even with that, you can't include the entire article ... please review rule # 2.

    I've deleted the majority of it this time, and know i've already warned you about this before, so be careful.

    This may be your last warning about this rule, before being permanently banned ... and know ... others won't even get this.

    This is some special stuff ... just for you ... :love:

    Love You!

    :heart:
