Science Is Constantly Evolving

Discover the latest in climate change and evolution education news.

Periodically, people get het up when someone suggests that climate change might be, in some sense, related to changes in extreme weather patterns. Lately, the targets of this outrage were Bill Nye, the Science Guy, and Barack Obama, the President Guy. For all the reasons Chris Mooney discusses in…
People who downplay or deny evolution often forget that evolutionary processes have major, dynamic impacts on the quality and future of their lives. Case in point: microorganisms. I was thinking about evolution and microbes after listening to a recent Science Friday podcast . There was…
Recently delegates from around the world gathered in Bonn, Germany, for a UN conference to discuss how the nations of the world can reach a “new, universal agreement on climate change.” This agreement is meant to outline how nations will work together to reduce greenhouse gases and limit, to the…
In Part 1, I told you about my work with the 1918 influenza virus, and promised to tell you more about why the Highly Pathogenic Avian Influenza H5N2 (HPAIH5) influenza strain that is currently rampaging through chicken farms in the Midwest is unlikely to jump to humans. I ended Part 1 by…
