Evolution in Action

Scientists from Harvard Medical School and Technion-Israel Institute of Technology have ingeniously visualized the Escherichia coli evolution through ever increasing amounts of antibiotics. Inspired by a Hollywood movie billboard, the team constructed the so called Microbial Evolution and Growth Arena i.e. MEGA plate to be able to monitor bacteria’s movement, survival and resistance.

Breaking the Rules of Natural Selection with Gene Drives

There is a new era rising in molecular biology and it began with CRISPR technology (Clustered Regularly Interspaced Short Palindromic Repeats), which is a genetic modification tool based on bacterial immune system. Gene drives is another interesting mechanism to use for altering genes but in contrast with CRISPR/Cas system it can only function in sexually reproducing species, leaving viruses and bacteria out of the picture.
