...mental "natural selection," separating winners and losers as theorized by Darwin. "We are not contending that natural selection does not exist, but that in this instance it is a chemical process within human chromosomes that explains why humans have an explosive expansion of DNA repeats, and primates do no...'Male-targeting' bacterium's genome is deciphered
... their host to help ensure their own survival. The losers in that manipulation are always the males of the host organism. Depending on the specific pair of Wolbachia and host species involved, the host males are either killed, converted into females, or prevented from successfully fertilizing the eggs of un...UC Riverside to convene conference on genetically modified organisms, Oct. 14-17, 2003
... not have access to this technology. There will be losers as well as winners in this global competition." Chase-Dunn pointed out that social scientists have always studied the causes and consequences of new technologies. "We want to understand the circumstances under which innovation occurs and the socia...Laboratory 'theme park' re-creates RNA world for study
...tube and tested again for the same ability. Again, losers are removed, and winners multiplied. As this cycle repeats, slight mutations often appear in the RNAs, some of which create molecules superior to the parent molecule. Says Bartel, "Really, we end up selecting for the survival of the best molecules, a...Ancient pollen yields insight into forest biodiversity
... similar it just takes a long time for winners and losers to be sorted out by competition," said Clark. "But eventually the better competitor would drive the other to extinction." Direct observations to distinguish which model is correct would take centuries, said Clark, "So in this study we came up with a...Virginia Tech leads global effort to sort out social, economic impacts of agricultural biotechnology
...iotechnology is also likely to produce winners and losers as a result of social and economic impacts, says George Norton. The professor of agricultural and applied economics at Virginia Tech says sorting out these social and economic effects may be critical to public acceptance of biotechnology. Without tha...
