Google "Hindawi journal scam". These guys regularly send me spam soliciting publications, and are most likely a thinly veiled paper factory. I wouldn't trust a thing I read in a Hindawi "journal".

That's really interesting.

    The RF shielded group evidenced more vigorous growth,
    producing 74% more total leader length and 60% more leaf 
    area than the mock-shielded group, though the number of 
    leaves produced by both groups was nearly the same.

    Leaves on active leaders in the shielded group were 
    substantially free of leaf tissue lesions (Figure 7), but 
    unshielded and mock-shielded leaves were all affected to 
    some extent by leaf tissue necrosis (Figure 8)

Just like in the electronics-on-airplanes issue, it concerns and wonders me that there isn't more research being done in such basic areas.
