on the evolution rate of the semenogelin protein against the level of female promiscuity, we saw a clear correlation whereby species with more promiscuous females showed much higher rates of protein evolution than species with more monogamous females...
A new target for control of obesity

suggested that in humans, the severity of age-related cognitive decline is affected by the genetic background of the individual. This was also the case for the genetically engineered mice. By manipulating the genetic background of the mice, the inves...
Genetically engineered corn poses no immediate threat to Mexican crops
...netically engineered or not. "Reliable unpublished data
suggest that it is extremely likely that some GM corn is already growing in Mexico, whether it was intentional or not," said Snow, who is also an expert on plant-to-plant transmission of GM genes. "What no one knows, however, is how common this has b...
