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
In some individuals, an influenza A virus infection can cause asymptomatic Staphylococcus aureus (S. aureus) to travel to the lungs where it can trigger severe, sometimes deadly, secondary pneumonia. S. aureus is one of the most common causes of secondary bacterial pneumonia in cases of seasonal... Read More
Microbial communities are essential drivers of soil functional processes such as nitrification and heterotrophic respiration. Although there is initial evidence revealing the importance of soil type in shaping microbial communities, there has been no in-depth, comprehensive survey to robustly es... Read More

Exposure to reactive oxygen species, exposure to ionizing radiation, exposure to UV light – all of these are dangerous because of their potential to alter DNA sequences. Changes in DNA can affect a protein coding sequence, potentially influencing its function, but changes in regulatory regions c... Read More
Many components of our oral hygiene regimens are meant to keep cariogenic bacteria at bay: sodium fluoride in ACT interferes with electron transport and ATP synthesis, the essential oils in Listerine have antiseptic effects, and abrasives – small, insoluble particles in toothpaste – help remove ...

Single-celled organisms called bacterioplankton spend their lives drifting in open ocean, visible to the naked eye only en masse. But don't be fooled by their slight size: These minuscule critters play a hefty role in the carbon cycle. Heterotrophic microbes, by some estimates, process half of t... Read More
Imitation may be the sincerest form of flattery, but it can also be the easiest way to make a buck. That’s the primary motivation for camouflaging within an already-established brand: Sunbucks, McDowell’s, and Mountain Lightening all rely on brand recognition – of a brand that isn’t their own. W...

In the year 2000, Kathleen Alexander, DVM, PhD, now a professor, at the Department of Fish and Wildlife Conservation, Virginia Tech, Blacksburg, Virginia, was working as a government veterinarian in Botswana, when a sickly banded mongoose wandered onto the grounds where she worked. When the mamm... Read More
There’s no way to avoid the news of a growing concern for drug-resistant infections. In both life-threatening and relatively superficial infections, the ability to successfully treat microbial infections with antimicrobials is decreasing. Our only recourse is to use the drugs we have carefully w... Read More
At St. Jude Children’s Research Hospital in Memphis, Tenn., scientist Stacey Schultz-Cherry has been studying the impact of obesity on influenza severity.
“We saw during the 2009 flu pandemic that there’s an epidemiological link between people getting severe flu and being obese,” says Schultz... Read More
The TWiP troika solve the case of the Female from the Bronx, and reveal how feeding on different plants affects mosquito capacity to transmit malaria.
Microbiome research has revealed that there are good guy and bad guy bacteria living together in complex communities on our skin, in our mouths, throughout our guts and pretty much everywhere in between. But what do you call a good guy bacterium that is aiding and abetting a disease culprit?

Some of the most popular segments at conferences, such as Microbe 2016 coming up in in Jun, are those that give continuing medical education (CME) credit to participants. These CME credits are an important part of being an active medical professional: they keep participants current on best pract... Read More
A common denizen of the undergraduate microbiology laboratory, Serratia marcescens is well known for the production of a bright red pigment, prodigiosin. Prodigiosin has been investigated over many years for its possible antimicrobial, antifungal, and even antitumor effects. Still, the relevan... Read More
The latest Zika virus news from the ConTWiVstadors, including a case of female to male transmission, risk of infection at the 2016 summer Olympics, a DNA vaccine, antibody-dependent enhancement by dengue antibodies, and sites of replication in the placenta.
So another Earth Day has come and gone. How did you spend yours? If you spent the entire day asleep, you used about half a kilogram of oxygen. Since I assume that you are alive and kicking, you probably consumed more oxygen than that. If you went about your normal business during the day, you pr... Read More
The discovery of antibiotics (also referred to as antimicrobials) is perhaps the most revolutionary outcome in the medical sciences during the twentieth century, and has allowed medical practitioners to treat a wide range of bacterial infections; and therefore, antimicrobials are the most common...
