drorzel | April 19, 2011The New York Times had another article on the environmental impacts of shale gas drilling, which reminded me that I had intended to write something else on the subject after February's post on the fracking panel at AAAS, but never got around to it. The hook for the article is yet another study showing that the environmental questions are more complicated than just the question of how much CO2 is released in burning gas vs oil or coal, with loss and leakage during the drilling process potentially producing a lot of greenhouse gases.
This is, of course, a single study, and includes the…
oracknows | April 19, 2011I'd like to thank Buckeye Surgeon for reminding me of something I had seen and wanted to blog about but totally forgot about. Maybe it was so forgettable that I should just skip it, but as a surgeon I actually don't think so. Basically, it's a story of a surgeon making a fool of himself. I know, I know, that's such an impossibility that it's well nigh inconceivable, but it actually did happen. Perhaps what brought my attention to this sordid tale is that there is a connection to the University of Michigan, where I went to both undergraduate and medical school.
The surgeon in question is Dr.…

View from Shizugawa high school as the tsunami comes in.
Very powerful and disturbing footage.
drorzel | April 18, 2011 It's been a while since I wrote up a ResearchBlogging post, but since a recent paper forced me to update my "What Every Dog Should Know About Quantum Physics" slides with new pictures, I thought I should highlight the work on the blog as well. Not that you could've missed it, if you follow physics-y news-- it's been all over, getting almost as much press as rumors that some people whose funding will run out soon saw something intriguing in their data. So, in the usual Q&A format:
OK, what's this about? Well, the paper title, "Quantum interference of large organic molecules" pretty well…
bioephemera | April 15, 2011How do you get kids to master science, math, and engineering? Ask them to make a video game that teaches it to other kids. Check it out:
One of these kids wrote a video game to teach himself his multiplication tables. Another calls his elementary school cousins his "user test group." I clearly am way, way, older than I ever realized I was. I learned to "program" by writing long strings of BASICLOGO commands for a "turtle" which could. . . drumroll. . . draw lines. Pathetic.

Anatomical engraving from Henry Gray's Anatomy, 1858.
A month or so ago, Abrams books reached out to mention that they were releasing a new title, Human Anatomy: A Visual History from the Renaissance to the Digital Age. I said, "don't I already have this book?" It turns out I did - I had the previous, hardback edition which I picked up for $25 or so on Amazon (a deal, I thought at the time). So I knew this book should really be subtitled "vintage eye candy from Vesalius to Schmiedel," because it's a bundle of rich images from anatomical atlases, interspersed with just enough curation to give…
drorzel | April 15, 2011Regular blogging has been interrupted this week not only because I jetted off to southern MD but because this week was the due date for the manuscript of the book-in-progress. It's now been sent off to my editor, and thus begins my favorite part of the process, the waiting-to-see-what-other-people-think part.
I'm pretty happy with it, though it's a bit longer than it was originally supposed to be. This is no doubt partly due to the fact that I'm too close to the thing at the moment, and can't see the obvious places where I could cut material, but that's why professional editors get the big…
bioephemera | April 14, 2011"Reasoning was not designed to pursue the truth. Reasoning was designed by evolution to help us win arguments."
- Jonathan Haidt, "The New Science of Morality",
invoking the work of H. Mercier and D. Sperber.
(the whole talk is really interesting).
drorzel | April 12, 2011I'm in last-minute-revision mode here, made mroe frantic by the fact that SteelyKid developed a fever yesterday, and had to be kept home from day care. I did want to pop in to note that I will be giving the Natural Science and Mathematics Colloquium at St. Mary's College in Maryland tomorrow, Wednesday the 13th. This will be the "What Every Dog Should Know About Quantum Physics" talk, described for the colloquium announcement as:
Quantum physics, the science of extremely small things like atoms and subatomic particles, is one of the best tested theories in the history of science, and also one…
rootbern | April 11, 2011Most people are at a loss to be able to identify any useful connections between arts and
sciences. This ignorance is appalling. Arts provide innovations through analogies, models, skills,
structures, techniques, methods, and knowledge. Arts don't just prettify science or make technology
more aesthetic; they often make both possible.
That cell phone or PDA you're carrying? It uses a form of encryption called frequency hopping to
ensure your messages can't easily be intercepted. Frequency hopping was invented by the composer
George Antheil in collaboration with the actress Hedy Lamarr. Yeah,…
bioephemera | April 9, 2011Adam Winnik sent me this animation inspired by Carl Sagan's famous "pale blue dot" monologue. It's true to the serious implications of Sagan's words, yet wry and lighthearted (mostly). A lovely example of remix culture revitalizing a classic of biology.
Adam gives some background:
I've been enrolled in illustration at Sheridan College for the the last 4 years and this is my final thesis project. I have always thought of Carl Sagan's writings as "scientific poetry" since they lack the cold touch that science is often cursed for having. I think Sagan's words resonate more than ever, and will…
bioephemera | April 8, 2011While we're on the bioanimation topic, I recently heard from Jess at Nervous System, who sent me links to some animations of their new jewelry line, hyphae, "growing" in virtual space. Check it out:
Hyphae - growth of the Vessel Pendant from Nervous System on Vimeo.
They explain,
Hyphae is a collection of 3D printed artifacts constructed of rhizome-like networks. Inspired by the vein structures that carry fluids through organisms from the leaves of plants to our own circulatory systems, we created a simulation which uses physical growth principles to build sculptural, organic structures.…
bioephemera | April 8, 2011Remember when I said more bio grad students should play with coding and modeling? Here's an example of what I mean. Laurence Frabotta directed me to this animation by phylogeneticist/bioinformatics programmer Liam Revell, an assistant professor at U Mass Boston, who used the statistical package 'R' to write a short code generating all possible bifurcating and multifurcating phylogenetic trees for a set of taxa. Apparently there are 2,752 for seven taxa (I have to take his word for it, my basic math skills have long since escaped me) and this animation runs through all of them. It's not…
drorzel | April 8, 2011It's college admissions season, which means a steady influx of high-school seniors thinking about coming here next year, making campus visits. Most of these students sit in on at least one class, to get an idea of what it's like. Which occasionally leads to odd things, but nothing stranger than what just happened: a prospective student just sat in on my junior/senior level elective class on quantum mechanics in the state-vector formalism. I suspect he didn't get a whole lot out of today's lecture, on changing state vectors and operators from one basis to another. In fact, I suspect this might…
drorzel | April 7, 2011A few weeks ago, I gave a talk based on How to Teach Physics to Your Dog for the University of Toledo's Saturday Morning Science program. At that time, their local PBS affiliate recorded the talk, for use on their very nice streaming video site, Knowledgestream.org. My talk is now up, and the video is hopefully embedded below:
I haven't listened to the entire thing, but I watched the first 10-15 minutes, and it's pretty good. the sound is coming from a microphone on my shirt, so you can't really hear any of the audience reaction (I got some good laughs in appropriate places), and in places…
bioephemera | April 6, 2011Wow - my post about unhappy bio grad students is getting massive traffic. (Hi SlashDotters and StumbleUpon-ers!) Mike the Mad Biologist, my original inspiration, has responded here and here to all the buzz.
I pretty much said everything I wanted to say in the original post, and I don't pretend to have an explanation or cure for this problem. But I see that there's been some snarkiness on the intertubez (shocking!!!) while I was away watching the developments in the Myriad appeal. So I want to clarify two points.
First, let me emphasize that I'm not saying graduate students in other fields don…
pharyngula | April 6, 2011This cartoon. Why? Because the first thing I do in the lab is hammer them on basic statistics, show them how to calculate p values, and struggle to keep them from over-interpreting their results.
bioephemera | April 5, 2011The oral arguments in Monday's Myriad appeal are online here. (Scroll down and look for Association for Molecular [Pathology] v. PTO).
bioephemera | April 3, 2011Tomorrow morning, a three-judge panel of the Court of Appeals for the Federal Circuit will hear arguments in the appeal of Association for Molecular Pathology v. U.S. Patent and Trademark Office - better known as the Myriad gene patent case.* It has the patent and genetic blogospheres in a bit of a tizzy, and the mainstream media is picking up on it too. See, for example, this Atlantic article by Andrew Cohen, this Nature.com editorial by my friend Shobita Parthasarathy, and even a "Spectator's Guide to the Myriad Oral Argument" by Genomics Law Report -- which has a dedicated icon and…
drorzel | April 2, 2011Thursday's post about the troubles of biomedical scientists drew a response from Mad Mike saying that, no, biomedical science Ph.D.'s really don't have any career options outside of academia, and pointing to Jessica Palmer's post on the same subject for corroboration. Jessica writes:
This is something I've tried to explain many times to nonscientists: most of the esoteric techniques I mastered during my thesis aren't useful outside a Drosophila lab. They're not transferable to any other field of biology, let alone any other scientific or nonscientific profession. Those skills I picked up on…
