Understanding primate evolution could aid HIV research (3/3/2008)

Evolution moves in fits and starts, shaping species through random genetic mutations that can help them survive or even hasten their death. But although the mutations occur by chance, the process can create surprisingly similar results. Now, in a startling twist, new research has provided an example in which evolution didn't just result in similar outcomes - it actually repeated itself, occurring the same way twice. Scientists at Rockefeller University and the Aaron Diamond AIDS Research Center have shown that nearly the exact same mutation occurred twice, in two monkey species that live on opposite sides of the world from each other. And while the change evolved independently in each case, in both species it plays a distinct role in how the animals fend off disease. ...> Full Article

Scientists explore factors contributing to DNA mutations (1/31/2008)

A team of Penn State researchers is the first to conduct a genome-wide study to compare the relative importance of factors that contribute to DNA mutations, which are implicated in cancer and more than 40 neurological disorders. Led by assistant professor of biology Kateryna Makova, the group investigated the simultaneous effects of numerous factors that are thought to increase the susceptibility to mutations of microsatellites -- variable-length sequences of recurring DNA subunits. Microsatellites are common throughout the genomes of plants and animals. The work is described in the January issue of the journal Genome Research. ...> Full Article

Genome-wide Study Shed Lights On Factors That Contribute To DNA Mutations (1/29/2008)

A team of Penn State University researchers is the first to conduct a genome-wide study to compare the relative importance of factors that contribute to DNA mutations, which are implicated in cancer and over 40 neurological disorders. Led by assistant professor of biology Kateryna Makova, the group investigated the simultaneous effects of numerous factors that are thought to increase the susceptibility to mutations of microsatellites -- variable-length sequences of recurring DNA subunits.
