vlicata | December 21, 2010I've been strangely fascinated by the "arsenic-eating" and maybe "arsenic-utilizing' bacteria report from NASA researchers and the so-called "backlash" ("arsenic-gate") in the blogosphere. Many others have posted on this topic. What I've found most interesting is that there seem to be several parallel and barely intersecting universes: 1) the scientific literature, 2) the traditional media, and 3) the blogosphere.
Universe 1: Wolfe-Simon has published for several years about the potential for unique
arsenic metabolism (among other topics), and this is the next paper in her series of…
oracknows | December 20, 2010During the six years of its existence, one frequent complaint I've had on this blog, it's been about how the press covers various health issues. In particular, it's depressing to see how often dubious and even outright false health claims, such as the claim that vaccines cause autism, that cell phones or powerlines cause cancer, or that various questionable or even quack remedies work for various diseases are reported credulously. Often this takes the form of a journalistic convention that is more appropriate for politics and other issues but not so appropriate for scientific and medical…
bioephemera | December 17, 2010Google Labs just released a new "experiment" - Body Browser. You have to upgrade to Google Chrome beta if you don't already have it, but when you do, you can play with a 3-D, rotatable reconstruction of a (female) human body. Sliders let you fade the circulatory, skeletal, muscular, and nervous systems in and out over the body organs; you can toggle labels on and off, and you can zoom, spin, and rotate in a way that would only be cooler if it were on a touchscreen iPad. (Yeah, that's what I said, Google. Do it!) Check out this screenshot:
Toggle a few sliders and you can wrap the vessels and…
bioephemera | December 17, 2010Euw! Ed Yong has a gross-yet-cool post about parasitic nematodes that infect and kill caterpillars - and bring along luminous bacteria whose red glow is unpalatable to birds. If a bird eats the caterpillar host, the parasitic worms die. But the bacterial warning glow protects the worms' immobilized corpse home until they mature and burst out of the dead caterpillar - as grossly as possible, of course. (See photo on Ed's blog).
Natural, uber-gross bioephemera! Thanks, Ed. :)
oracknows | December 17, 2010NOTE: Orac was actually out rather late last night. It turns out that the more administrative responsibility he somehow seems to find the more he has to go out to dinner as a part of various cancer center-related functions. As a result, he is recycling a bit of recent material from elsewhere that he in his extreme arrogance considers just too good not to post up on this blog too. In any case, it's always interesting to see how a different audience reacts to his stuff, and he did make some alterations to this post.
'Tis the season, it would seem, for questioning science. Not that there's…
bioephemera | December 13, 2010This is un freaking real.
My friend John O at Armed With Science has dug up a classic animated film produced for the National Naval Medical Center in 1973. It starts with an awards ceremony for the "Communicable Disease of the Year," hosted by the Grim Reaper (who turns out to know a lot about medical history.)
The top prize is won by the Dracula-esque Count Spirochete (AKA syphilis), over the vociferous objections of a shortlist of other diseases, including smallpox ("I've scarred and disfigured millions of people!") and gonorrhea (who resembles a lavender Tribble with a pitchfork). The…
oracknows | December 11, 2010Has it really been six years?
Six years ago today, on a dim and dreary Saturday in December, almost on a whim I sat down, went to Blogspot, and started up the first version of Respectful Insolence with an introductory post with the cliched title, Please allow me to introduce myself. Here it is, six years later. On this cold December Saturday, I still find it difficult to his blog is considered one of the "top" medical blogs by one measure, and some actually--shockingly--consider me somewhat of a "famous" skeptic. I know, I know, I still can't wrap my head around the concept myself. At least,…
bioephemera | December 10, 2010Diptheria vaccinations in the 1920s
The town of Leicester was a particular hotbed of anti vaccine activity and the site of many anti-vaccine rallies. The local paper described the details of a rally: "An escort was formed, preceded by a banner, to escort a young mother and two men, all of whom had resolved to give themselves up to the police and undergo imprisonment in preference to having their children vaccinated...The three were attended by a numerous crowd...three hearty cheers were given for them, which were renewed with increased vigor as they entered the doors of the police cells." The…
bioephemera | December 8, 2010This video from the University of Minnesota's Institute on the Environment is like a conservationist's version of the "Right Here, Right Now" video about social media (although the music isn't as good). It has crisp design, good infographics, and makes a very important point: that nature has massive, unappreciated economic value.
I'm not saying that money should be the main reason for environmental protection; I value nature for purely aesthetic and scientific reasons, over and above economics (although aesthetics and science both have economic value - realized through tourism and R&D).…
tfk | December 7, 2010I'm so glad I didn't blog about the arsenic bacterial. The paper's basic methods were probably flawed, and NASA won't defend themselves. In short, we don't know yet whether there's even a story yet, let alone one deserving a press conference.
"We cannot indiscriminately wade into a media forum for debate at this time," senior author Ronald Oremland told Carl Zimmer. Which would be fine if they hadn't kicked this story off with a well-hyped press conference. But they've already waded into that media forum, and done so fairly indiscriminately. Maybe wading discriminately into a discussion…
bioephemera | December 2, 2010Okay, you've probably heard the buzz about the "arsenic organism" supposedly discovered in Mono Lake, and how NASA's 2pm press conference today will reveal more. I'll be honest, I wasn't that excited about it - extremophile bacteria metabolize some freaky stuff, and it seemed pretty clear the announcement wasn't about extraterrestrial life. But Gizmodo is now claiming the critter has arsenic based DNA.
Did April Fools Day relocate to December? I'll believe this story when I hear it from the researcher herself, but that would be SO COOL. I'm getting my wide-eyed-awestruck-biologist hat out of…
oracknows | December 1, 2010No, no, no, no, no!
I hate it when a fellow ScienceBlogger goes astray!
Fortunately, it's been a long time indeed since I felt obligated to administer a dose of Insolence, Respectful or otherwise, to a fellow ScienceBlogger. It's been even longer (as in, I think, never) that I've ever seen one whose resource I use regularly screw up so amazingly. I'm talking about Coby of A Few Things Ill-Considered, whose How To Talk To A Climate Skeptic (also found here) is a resource I turn to again and again and again when faced with denialist arguments about anthropogenic global warming. Indeed, I've…
bioephemera | November 28, 2010Yes, that's what I said - Gunther von Hagens has a gift shop, and he's selling earrings and necklaces made of slices of equine and bovine genitalia. Don't like ostentatious, plastinatious penis jewelry? There's always a bull penis vasculature walking stick.
I had to blog these, but honestly, I didn't really want to know they existed at all.
bioephemera | November 26, 2010
All shopped out? I can pretty much guarantee that difficult person on your gift list does not have a huge, one-of-a-kind mama Emperor scorpion carrying baby scorpions made of fleece, felt and pom-poms.
At $200, this plush scorpion sculpture may sting your pocketbook, but seller weirdbuglady also offers more affordable amoebas, tardigrades, fossils and insects. Check out her etsy shop and her blog.
bioephemera | November 26, 2010Okay, so is this the perfect job for me or what?

The Liberal Arts department provides the general education component of Massachusetts College of Art's BFA degree program. Successful candidates will help build an academic program in collaboration with colleagues from non-…
oracknows | November 22, 2010You may have noticed that there wasn't the usual 3,000 word heapin' helpin' of Insolence this morning. That's because I happened to be away visiting family in Chicago over the weekend and I just didn't have time to come up with anything--and I enjoyed myself too thoroughly to worry overmuch about it. In case you're wondering, the posts that went up over the weekend were either written before I left or so short that they took me five or ten minutes to do.
Sort of like this post.
Unfortunately, this morning I did see something of interest that disappointed me enough that I took a bit of time…
bioephemera | November 19, 2010This year's winner of the BioScapes digital imaging competition, Igor Siwanowicz, triumphed with a somewhat unusual portrait. To most biologists, it should be clear what anatomical structures are shown here - but what species could this be?

bioephemera | November 18, 2010Hannah Waters at Culturing Science has written a lovely little post on the day-to-day benefits of having a scientific worldview:
I grew up immersed in science. Any facts that exist that I couldn't reconcile with experience, I just chalked up to the limitations of my senses or even my brain's ability to conceptualize (the latter usually reserved for when I'm dealing with astrophysics). But if you aren't well-versed in how science works and perhaps the basics, this stuff sounds completely insane!
Read more here. While I'm not quite as optimistic that the power of awesome, or science…

The New York Times decided earlier this week that biological animation warrants its own article. About time! :)
Seriously, for those of you who haven't discovered BioVisions' amazing animations, you should check them out and/or use them in class - with the caveat that they're not "pure" data:
While acknowledging the potential to help refine a hypothesis, for example, some scientists say that visualizations can quickly veer into fiction. "Some animations are clearly more Hollywood than useful display," says Peter Walter, a Howard Hughes Medical Institute investigator at the University of…
bioephemera | November 12, 2010With a poster titled "WE NEED YOUR BODY! For a UNIQUE OPPORTUNITY," microbiologist Steven Park and artist Anne Brodie invited attendees at the British Science Festival to
stand NAKED inside our live bioluminescent photograph booth and have your photograph taken. Enveloped by a living ethereal blue green light, the resulting faint and ghostly image will be used as part of an [art] installation. . .
The eerie results, which look a whole lot like TSA millimeter-wave scans, are appearing in an exhibition at the UK's Royal Institution through December 3. See a slideshow at the Londonist.
