Chemical in broccoli blocks growth of prostate cancer cells

Those seeking yet another reason to eat their veggies, take note. Researchers at the University of California, Berkeley, have found that a chemical produced when digesting such greens as broccoli and kale can stifle the growth of human prostate cancer cells. The findings show that 3,3′-diindolylmethane (DIM), which is obtained by eating cruciferous vegetables in the Brassica genus, acts as a powerful anti-androgen that inhibits the proliferation of human prostate cancer cells in culture tests.

Genetically modified cotton crops produced greater yields, reduced pesticide use

Cotton crops in India that were genetically modified to resist insects produced dramatically increased yields and significantly reduced pesticide use compared with non-bioengineered crops, according to the results of farm trials reported by researchers in California and Germany. The study, published Friday, Feb. 7, in the journal Science, holds particular promise for small-scale, low-income farmers in developing nations, said the researchers. These farmers, especially those in tropical regions, regularly risk large, pest-related crop losses because they cannot afford to use the pesticides available to larger farms.
