Bt cotton in China fails to reap profit after seven years

... cotton - found that by year three, farmers in the survey who had planted Bt cotton cut pesticide use by more than 70 percent and had earnings 36 percent higher than farmers planting conventional cotton. By 2004, however, they had to spray just as much as conventional farmers, which resulted in a net averag...

Stanford snake venom study shows that certain cells may eliminate poison

...li. Galli and Metz are embarking on a systematic survey of animal venoms. As more is learned about the natural defenses the mammalian immune system has against venom, it may someday even lead to better antivenins, though it will first have to be shown that human mast cells respond in the same way mouse ma...
