Pew report finds GM insects may offer benefits, but clear regulatory oversight is lacking

the major concern regarding regulation is the absence of a clear articulation of how transgenic insects will be regulated. While a number of laws could potentially apply to GM insects, federal regulators have not indicated if they would regulate GM i...

that collisions with interplanetary dust will quickly erode the ejected boulders to much smaller fragments and that these tiny, life-bearing fragments may be driven out of the solar system by the pressure of sunlight in a few years. The solar system ...
