Insects develop resistance to engineered crops

...velop resistance to all the insect-killing plants, report Cornell University researchers. A soil bacterium called Bacillus thuringiensis (Bt), whose genes are inserted into crop plants, such as maize and cotton, creates these toxins that are deadly to insects but harmless to humans. Bt crops were first co...

Pinpointing a culprit molecule in Alzheimer's disease

... Todd Golde of the Mayo Clinic College of Medicine report in the July 21, 2005, issue of Neuron definitive proof that Ab42 is, indeed, the culprit molecule. In their experiments, they created transgenic mice that overproduced either Ab40 or Ab42 in the absence of overproduction of APP. Thus, they could prec...
