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
Surgery has been the standard treatment for appendicitis for more than a century. Millions of appendectomies are performed annually in the world, more than 300,000 in the US alone. Studies have been carried out over the years to determine whether non-perforated appendicitis could be treated with... Read More
Treatment and prevention of life-threatening infections could be improved by research that reveals how bacteria are kept in check.
Researchers have discovered how the immune system stops bacteria in our gut from leaking into the blood stream and causing body-wide inflammation, such as sepsis.... 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
BOULDER - Key factors that can combine to produce a Zika virus outbreak are expected to be present in a number of U.S. cities during peak summer months, new research shows. Read More
A clinical trial in which volunteers were infected with dengue virus six months after receiving either an experimental dengue vaccine developed by scientists from the National Institutes of Health (NIH) or a placebo injection yielded starkly contrasting results. All 21 volunteers who received th... Read More
A number of BZ anthelmintics used in veterinary medicine have been considered for transition to human use, including oxibendazole and oxfendazole (OXF). In addition, flubendazole, already approved for use as an intestinal anthelmintic, is also being developed as a treatment against adult filaria... Read More
Jean-Paul Latgé originally wanted to know if he could test the breath of patients with Aspergillus infections for volatile compounds produced by the fungus. His group at the Pasteur Institute in Paris thought this might be a new way of diagnosing fungal culprits like Aspergillus fumigatus that o... Read More

Evidence is mounting that Zika virus is neurotropic (able to infect cells of the nervous system) and neurovirulent (causes disease of the nervous system) in humans. Read More
I was asked to write a commentary for the Proceedings of the National Academy of Sciences to accompany an article entitled SARS-like WIV1-CoV poised for human emergence. I’d like to explain why I wrote it and why I spent the last five paragraphs railing against regulating gain-of-function experi... Read More

Droplets due to respiration or possible antibiotic production seen in the center of a mold colony. Mold grew pink in the center with green spore formation around the edges and a white non spore forming "apron" This is a fairly common environmental contaminant seen in our lab , presumably airbo...
