Mutations are the raw material of evolution. Scientists have now been able to measure for the first time directly the speed with which new mutations occur in plants. Their findings shed new light on a fundamental evolutionary process. They explain, for example, why resistance to herbicides can appear within just a few years.

Scientists recently discovered a simple gene mutation that decreases the chance people will get a flesh-eating disease called necrotizing fasciitis. Further, they proved that inactivating this section of the gene lessens the devastating disease in humans.

Scientists have determined for the first time that prions, bits of infectious protein devoid of DNA or RNA that can cause fatal neurodegenerative disease, are capable of Darwinian evolution.
