  • Are genetically-modified organisms now safer? Scanning electron micrograph of Escherichia coli, grown in culture and adhered to a cover slip. Credit: Rocky Mountain Laboratories, NIAID, NIHGenetically modified organisms (GMOs) have amazing potential for improving lives, from providing nutrients to undernourished populations to cleaning up pollutants to synthesizing drugs on large scales. Yet escape of GMOs into the environment could upset nature‚Äôs balance, just as invasive species can cause extinctions of native species. Recently, researchers have effectively encoded safety locks into…

  • The Physics of Evolution: Equations shed new light on nature’s mysteries physics-of-evolutionPresented by Jeong-Mo Choi, Bryan Weinstein, and Amy Gilson Did you know that principles and equations from physics can be used to study evolution? We'll describe how physics-based models can be used to predict evolution, on the level of individual molecules and whole populations. First, Jeong-Mo will describe how scientists began to use quantitative models…
