By way of Matthew Yglesias, we read that,over at National Review Online, Kevin Williamson claims progressives only care about science as a way to wage culture war (yes, coming from movement conservatives, that’s rich): There are lots of good reasons not to wonder what Rick Perry thinks about scientific questions, foremost amongst them that there…

ScienceBlogling Tara Smith has a great summary of the recent paper reporting high frequencies of multi-drug resistant Staphylococcus aureus in uncooked meat products (S. aureus is the “SA” in MRSA–methicillin resistant S. aureus, so I won’t go through the whole paper here (and Maryn McKenna, as usual, had the best early report). But there are…

Since I’m going on vacation, I might not get to it right away, but the NY Times has a good article about two studies that appear to contradict each other about various effects to control hospital-associated MRSA infections. I haven’t given the two article an in-depth reading yet, but it seems to me that the…

Consider this the post wherein I channel my Inner ERV. During the last week, I’ve come across a couple sensationalist article about E. coli and Staphylococcus aureus being found on common surfaces. Here’s one article about shopping carts and E. coli: Researchers from the University of Arizona swabbed shopping cart handles in four states looking…

So Google has released this Ngram thingee that searches for words in all of the archived Google stuff. So I decided to look for the words “MRSA”, “staphylococcus”, and “Staphylococcus.” Here’s what I found:

When biologists refer to the ‘wild type’, we mean that there is a dominant phenotype or trait that most organisms in a species possess. For example, most Drosophila melangaster (the fly commonly used in genetics) have red eyes–red eyes are the wild type, while white eyes are often referred to as the ‘mutant’ phenotype. If…

Two Thoughts About MRSA ST239

Maryn McKenna has a good article about a new strain of methicillin resistant of Staphylococcus aureus, ST239, aka The Brazilian Clone (as far as I know, no bikini wax is involved…). ST239 is troubling since it’s not only resistant to methicillin, but also resistant to other antibiotics, including clindamycin, tetracycline, cotrimoxazole (also known as Bactrim),…

No, MR-CoNS isn’t some kind of crazy new conservative, it stands for methicillin resistant coagulase-negative staphylococci. CoNS are relatives of the bacterium Staphylococcus aureus (the ‘SA’ in MRSA), and are common human commensals–they typically live on us and in us without causing disease. One of the important things, from a health perspective, about CoNS is…

It’s supposed to be rainy, so why not attend? Carl Zimmer will be there. MAS does really cool outreachy things like teacher training so they’re worth supporting, even if you can’t attend. Anyway, this found its way into my email machine: Join the Massachusetts Academy of Sciences as we spend a day at the Museum…

I’m conflicted about Nicholas Kristof’s recent op-ed about antibiotic resistant organisms. On the one hand, Kristof is one of the only national columnists to raise this issue at all. On the other hand, I found his most recent column somewhat confusing–and I’m an expert in this area (I also think he’s jumping to unfounded conclusions,…
