Doing Science
tsmith | May 31, 2017A claim that scientists need to quit making:
I've written about these types of claims before. The first one--a claim that antimicrobial peptides were essentially "resistance proof," was proven to be embarrassingly wrong in a laboratory test. Resistance not only evolved, but it evolved independently in almost every instance they tested (using E. coli and Pseudomonas species), taking only 600-700 generations--a relative blip in microbial time. Oops.
A very similar claim made the rounds in 2014, and the newest one is out today--a report of a "super vancomycin" that, as noted above, could be…

I'm happy to welcome Dr. Heather Lander to the blogosphere and Twitterverse. She's a virologist who has done work with some of the world's deadliest pathogens in a high-security biosafety level 4 laboratory. This is the type of lab where one must wear "space suits" to work with organisms. You've probably seen in dramatized in various movies and TV shows (such as The Walking Dead). Heather describes what it's really like to work in one--even while pregnant.

tsmith | February 26, 2014This week at #scio14, Danielle Lee is leading a discussion on privilege in science. I'd started this post and abandoned it a few weeks back, but I think it speaks to a similar phenomenon as she describes in her post. Low-income students are being lost not only to science, but often to the college experience in general. This is amplified at elite institutions, but even at the public institutions I've worked at, lower income students are at a significant disadvantage when it comes to preparing for any kind of graduate or professional post-bac training.
My first introduction to one of my…
tsmith | December 10, 2013While I loved Jeanne Garbarino's recent post, "Want to promote women in STEM? Leave home life out of the discussion", and agree with probably 90% of it, I think it unfortunately goes from one extreme to another with some of her recommendations.
Garbarino notes several reasons why she thinks it's counter-productive to discuss home life issues when trying to promote women in STEM careers: 1) it is rare that home life situations for men in STEM are discussed; 2) not everyone shares the same home life experiences or goals; 3) it doesn’t move the conversation forward. Very true for 1 and 2 (though…
tsmith | June 23, 2011I have written and deleted this post. Twice. But damn it, it needs to be said.
I'm here in charming Montreal for the North American Congress of Epidemiology. It's a good-sized meeting, as far as epi meetings go. The site notes that it's a joint effort between four major Epi organizations: The American College of Epidemiology (ACE); The Society for Epidemiologic Research; the Epi section of the American Public Health Association, and The Canadian Society for Epidemiology and Biostatistics. Collectively, those associations represent a lot of epidemiologists.
The conference started off well.…
tsmith | June 13, 2011Ah, classes are finally over. The last two summers I've taught a short, intense course in Applied Infectious Disease Epidemiology, condensing a semester's worth of work into a week. It's a fun course to teach, but exhausting--after teaching, I head back home or to the office to finish last-minute preparation for the next day's talks and assignments, and by the time that's done, the nightly student homework is rolling into my email inbox for me to grade and comment on for the next morning. By Friday, I feel like a zombie who hasn't seen my family in a week.
But, it's now wrapped up for…
tsmith | May 31, 2011I wasn't going to raise this comment en blogge, but with Dr. Isis' new post, it becomes more relevant. From Rick Fletcher on the "you're too pretty" post:
It's a major issue if your department won't hire your or promote you because you are a woman. It's no surprise that a retail clerk at a small shop in a downtown area is not the smoothest operator.
25 years ago it was a common response when I was introduced as a PhD chemist: "You don't seem like a scientist." Now it's a common response when introduced, "Why are you single?" People say some dumb things. Not exactly the news.
But again, it's…
tsmith | May 24, 2011This wasn't the post I wanted to write about the ASM conference. There's been lots of great science discussed (I've tried to tweet some of it, but the wifi in both the conference center and my hotel have been spotty, so I've not had a chance to write anything comprehensive). Instead, I'm ticked off and venting via dashed-off blog rant.
[Me, trying to make a purchase]: Do you have any of these in a box that doesn't say "from someone in New Orleans who loves you"? I was going to get them for my lab and that might be kind of creepy.
[Retail salesguy]: Your lab? I'm not sure those are good for…
tsmith | May 10, 2011Maryn McKenna was awesome enough to take some time out of her vacation to blog about our recent ST398 paper, finding "livestock-associated" S. aureus in a daycare worker. She raised one question I didn't really address previously, regarding our participation by kids and workers at the facility (eight kids out of 168, and 24 out of 60 staff members).
(Staph screening is very non-invasive, by the way; it effectively involves twirling a long-handled Q-tip inside the front of your nostrils. Kinda makes you wonder why families would not have wanted to participate. On the other hand, since Iowa is…
tsmith | November 18, 2010The second edition of the Rock Stars of Science is now out online, and in the November 23rd ("Men of the Year") edition of GQ magazine. As Chris Mooney notes, this is a campaign funded by the Geoffery Beene Foundation, working to raise recognition of scientists' work (and scientists, period, since roughly half of the American population can't name a single living scientist). Part of the campaign is to make science noticeable and "cool;" I'll quote from the press release:
ROCK S.O.S⢠aims to bridge a serious recognition gap for science, observes journalist Chris Mooney, co-author of the…
tsmith | September 30, 2010The Dog Zombie has an interesting post discussing women in vet med--and why there are so many. She notes that her school is only 12% male, versus more of an even distribution in med schools, and the recent discussion of gender imbalance in science blogging. This is interesting to me, as my personal vet is male, as are almost all of the vets we collaborate with for our research. Of course, the gender distribution of veterinarians in academia may well be more gender-balanced (or even male-skewed) than those currently in vet school or recently graduated.
DZ posits some possible reasons for this…
tsmith | September 16, 2010Interesting discussion over at The Spandrel Shop and Cackle of Rad on doing field work in the sciences--and the potential dangers that might be encountered. Now, Prof-like Substance and Cackle of Rad are discussing field work along the lines of biological sample collection, sometimes in the middle of nowhere, which isn't something I've ever done. However, we have our own issues when carrying out our epidemiological field sampling; more after the jump.
For new readers, my lab works on emerging infectious diseases, and zoonotic diseases (which can pass between animals and humans) in particular…

Update: 13 Aug. I've added a new post that I think provides a clearer explanation for the reason that this sort of behavior is such an irritant when it comes from a company like Elsevier.
Like most bloggers, I have an ego. I'm not mentioning that by way of apology, but as an explanation for why I was browsing through my sitemeter statistics last Friday. Every now and then, I head over to sitemeter, call up the view that lets me see what websites referred people to my page. If I see a link that's coming from a source I don't recognize, I browse over and look to see what people are saying…

Timo Hannay just responded, over at one of Nature's blogs, to the hordes of bloggers who were somewhat displeased with the tone and content of Declan Butler's recent Nature article. Now that someone from Nature has returned fire, and other bloggers have fired back, it's likely that this whole thing is going to turn into one of those multi-day, multi-article kerfuffles that do so much to maintain blogging's reputation as the WWE of the scientific world. Which is cool, as far as I'm concerned. It's been a while since I've grabbed a folding chair and climbed into the Cage of Death. I'm ready to…

Last Tuesday, I posted another one of my picture quizzes, asking what a particular device is, and what it's used for. Jonathan was the first to get the correct answer - it's a Niskin bottle. A Niskin bottle is used to collect a sample of water at a particular depth. It's put into the water with both ends open, so that water flows through it freely as it descends. When it reaches the desired depth, the two ends are sealed and water trapped inside. As Dave S. notes, the bottle in the picture is a small one, and it's being used in a low-tech setup.
The picture was taken during a field trip…

Earlier today, I raised the goal for my DonorsChoose challenge from $1588 to $2000. More of you donated, and within just a couple of hours we pulled to within $0.35 of the $2K mark. I've upped the goal by another $500. Since two of the proposals that I added earlier today are now fully funded, I'm adding one more. I was going to wait, but this one's a true heartbreaker - well beyond depressing. This proposal comes from P.S. 62 in the Bronx:
We have been instructed to cover up all of our blackboards which are old and ruined. As a result, I have to teach all of my lessons on chart paper that…
