Mutate Or Die: New Polymerase Gives Desperate Yeast An Option
...ds at staying alive, but it does so bydramatically boosting the type of mutations that, in humans and other animals, sometimes become the genetic seeds fromwhich cancers grow. The research by the University of Rochester team, done bycreating in yeast the type of damage that sunlight does to our own DNA, is ...Cornell Scientists Find Way To Boost Rice Crop Yield -- They'll Walk On The Wild Side
... to boost yield -- it's plateaued. So, instead of boosting land mass -- which we can't do -- we're manipulating the plant's genetics." In the case of rice, there has not been a significant yield increase in two decades. Yet the world's agriculturists are using only 25 percent of the genetic diversity availa......test cultures. The research also showed that both boosting the ratioof EGSs to target mRNAs and increasing the number of different target sites onthe mRNA enhanced the method's efficiency in restoring drug sensitivity, andalso prevented a return to drug resistance.
