Life Fast, Die Young: The Evolution of Aging

Originally posted on the LIFE Apps science blog... By Jordan Pennells To take care of your health is to delay the inevitable biological deterioration of your body, to fight against the unyielding aging process. But there’s another way to view the process of aging, if we expand the time frame from an individual’s lifetime to evolutionary time. … Continue reading Life Fast, Die Young: The Evolution of Aging

Agricultural Challenges (1)

Gene X Environment Interaction: As discussed in a previous post, agricultural biotechnologies developed in the 1990s resulted in increased yields, but these techniques were targeted towards traits controlled by a relatively simple pathway consisting of only a handful of genes (i.e. insect and herbicide protection). However, this was not possible for complex traits such as drought resistance, which … Continue reading Agricultural Challenges (1)

Agricultural Biotechnology

As genetic fingerprinting began to develop in the 1990s, molecular breeding (using DNA markers in combination with phenotypic measures to drive the development of new crop varieties) resulted in increased yields despite the drought-inducing action of climate change. These techniques primarily involved transgenes, foreign DNA from other species that could be incorporated into the crop genome … Continue reading Agricultural Biotechnology
