In this month's episode of the science show This Week in Evolution, Nels and I discuss the evolution of butterfly wing patterns. In this study of Amazonian butterflies, the authors show that distinct patterns are a consequence of enhancer shuffling. Enhancers are DNA sequences that control trans... Read More
What kinds of microbes do you associate with hot springs? Maybe microbial mats? Thermus aquaticus and the discovery of Taq polymerase? Archaea, previously (and erroneously) thought to be strict extremophiles? Viruses may not be the first microbial subtype that springs to mind (pun intended) but ... Read More
Because of its safety, efficacy, and affordability, chloroquine remains the treatment of choice for all Plasmodium species, except in regions with chloroquine-resistant P. falciparum. Chloroquine-resistant protists are treated with combination therapy, which includes artemisinin-derived molecule... Read More
