gregladen | April 10, 2008Things are happening exactly as I predicted...(Expelled! The Movie To Be Pulled From Theaters Following Myers/Dawkins-Gate Screwup)
The movie "Expelled!" with Ben Stein (you may have heard of it) includes a segment consisting of the animation of the inside workings of a cell. It is said to look a lot like a production that came out of Harvard and a private animation firm last year or so:
People who saw the clip used in Expelled! were beginning to think that the video Expelled! used was not the Harvard video because there were some differences. However, this remains unclear. My thinking on…
sporte | April 9, 2008You can find out. Blaine Bettinger, the Genetic Genealogist has a fun little quiz.
evolgen | April 9, 2008PLoS Biology's press releases have taken another step toward being dismissed as "crap" by people who know jack shit about evolution, thanks to a new press release published last week.
It starts off like so:
Evolution has taken another step away from being dismissed as "a theory" in the classroom, thanks to a new paper published this week in the online open-access journal PLoS Biology.
And goes on like this:
As all students of Darwin know, evolution occurs when there is variation in a population; where some variants confer a survival or reproductive advantage to the individual, and where the…
sporte | April 8, 2008I love using molecular structures as teaching tools. They're beautiful, they're easy to obtain, and working with them is fun.
But working with molecular structures as an educators can present some challenges. The biggest problem is that many of the articles describing the structures are not accessible, particularly those published by the ACS (American Chemical Society). I'm hoping that the new NIH Open Access policy will include legacy publications and increase access to lots of publications about structures.
It would also be great if other funding agencies, like the National Science…
gregladen | April 8, 2008Tim Pawlenty has demonstrated, in many ways and on many occasions, that he is the worst governor the State of Minnesota has ever had. The most recent proof was his line item veto of funding for the Bell Museum of Natural History, and his line item veto of the funding necessary to further develop public transit in the Twin Cities. Neither surprises me. This is the governor who gave us a creationist education director, and this is the governor who let the bridge fall down. Education and transportation are not his bailiwicks. But one has to ask, if he can't understand these two important…
gregladen | April 8, 2008Florida Senate Bill S2692 is up for discussion and a decision to pass to the floor by the Senate Judiciary Committee.
BELOW YOU WILL FIND LINKS TO EMAIL EACH MEMBER OF THE COMMITTEE (except one, for whom I provide a phone number).
I'd say you don't need to be a Florida resident to let them know what you think. In fact, let them know that the whole world is watching!
I've got to say that this is one of the scariest bills I've seen in a while. Have a look:
The Teaching of Chemical and Biological Evolution [SPCC]; Cites act as the "Evolution Academic Freedom Act." Provides public school…

gregladen | April 7, 2008Louisiana now has an Academic Freedom Act in the works. Academic Freedom Acts are right wing ploys to force specific issues ... or more commonly, specific politically or religiously motivated version of issues ... into the classroom at various levels. Academic Freedom Acts also typically are designed to silence faculty who teach things that conservatives, evangelicals, global warming deniers, and so on do not want to hear.
From a commentary in The Daily Advertiser:
Gov. Bobby Jindal's first regular-session legislative plan is designed to help Louisiana schools train a better work-force. So…
gregladen | April 5, 2008There is an updated version of this post here: "Is Blood Ever Blue, Science Teachers Want To Know!"
According to one of the leading experts on the human circulatory system, blood flowing through veins is blue.
I'm not going to mention any names. All I'll say is this: A person I know visited a major research center last year and saw a demonstration of organ removal and some other experimental stuff. A person also visiting asked the famous high-level researcher doing this work if blood was ever blue. What he said was not recorded in detail, but it was very much like this statement I found…
sporte | April 4, 2008This morning I had a banana genome, an orange genome, two chicken genomes (haploid, of course), and some fried pig genome, on the side. Later today, I will consume genomes from different kinds of green plants and perhaps even a cow or fish genome. I probably drank a bit of coffee DNA too, but didn't consume a complete coffee genome since my grinder isn't that powerful and much of the DNA would be trapped inside the ground up beans.
Of course, microbes have genomes, too. But I do my best to cook those first.
So, what is a genome? Is it a chromosome? Is it one of those DNA fragments or…
sporte | April 3, 2008Goodbye desktop, we're off to see the web.
Both my students and I have been challenged this semester by the diversity of computer platforms, software versions, and unexpected bugs. Naturally, I turned to the world and my readers for help and suggestions. Some readers have suggested we could solve everything by using Linux. Others have convincingly demonstrated that Open Office is a reasonable alternative.
But, now there's something new and cool on the web.
Okay, it's still in the beta stages, and apparently it can only be used by a limited number of people at a time, but it's certainly…
terrasig | March 30, 2008In attempting to re-engage my academic brain stem, I've been doing a little continuing education the last couple of weeks at various forums hosted by the University-That-Tobacco-Built. Last week I had the pleasure of attending a forum of the Duke student organization, Women in Science and Engineering (WiSE), that featured four academic leaders (who were women) and Bora Zivkovic discussing non-bench science careers.
One of the panelists was an old colleague, Dr Rochelle (Shelly) Schwartz-Bloom, an award-winning neuropharmacologist and educator in the Duke Department of Pharmacology &…
sporte | March 29, 2008Our new Scibling, Jane, is a real life computer scientist. If you've ever wondered what computer scientists really do during the day, Jane will set you straight (I guess they're not playing Nintendo. Darn! Another illusion shattered, just like that.)
Jane has also promised to explain why computer science is a science and not engineering.
That part hasn't happened yet, but I work with software engineers and I have written a bit about the mysterious things that they do. Databases need to vacuumed? Who knew?
I'm looking forward to hearing Jane describe answer the question from the…
gregladen | March 27, 2008Accepting his 2008 TED Prize, physicist Neil Turok speaks out for talented young Africans starved of opportunity: by unlocking and nurturing the continent's creative potential, we can create a change in Africa's future. Turok asks the TED community to help him expand the African Institute for Mathematical Sciences by opening 15 new centers across Africa in five years. By adding resources for entrepreneurship to this proven model, he says, we can create a network for progress across the continent -- and perhaps discover an African Einstein.
sporte | March 27, 2008I made this video (below the fold) to illustrate the steps involved in making a phylogenetic tree. The basic steps are to:
Build a data set
Align the sequences
Make a tree
In the class that I'm teaching, we're making these trees in order to compare sequences from our metagenomics experiment with the multiple copies of 16S ribosomal RNA (rRNA) genes that we can find in single bacterial genomes. Bacteria contain between 2 to 13 copies of 16S rRNA genes and we're interested in knowing how much they differ from each other. Later, we'll compare the 16S ribosomal RNA genes from multiple species…
jlynch | March 23, 2008Apparently Nisbet thinks we should desist from pointing out what a fiasco this whole affair has been for the supporters of Expelled. Apparently he thinks this is helping the enemy. He also thinks Dawkins and Myers should return to their seat at the back of the bus. Perhaps that might be true about "new atheism" (and I have stated my views on that before), but this isn’t about atheism. It is about a dumb move that was made by Mark Mathis and the supporters of Expelled. It is about how they are spinning their stupidity through lies and mistruths. It is about how their dumb little movie twists…
clock | March 22, 2008The new edition (first online edition) of Scope, the MIT Grad Program in Science Writing's student webzine, is out (hat-tip to Tom) with several great articles. Check out, for instance, Words (Just Might) Hurt Me: The Trouble with 'Theory'.
sporte | March 19, 2008Have you ever wondered how to view and annotate molecular structures? At least digital versions?
It's surprisingly easy and lots of fun.
Here's a movie I made that demonstrates how you can use Cn3D, a free structure-viewing program from the NCBI. Luckily, Cn3D behaves almost the same way on both Windows and Mac OS X.

sporte | March 19, 2008The University of Virginia does.
They survey students every year to find out what they're up to tech-wise. Apparently 99% of their first year students own computers.
And, a large majority of those computers are laptops (3058/3113 or 98%).
And, what's on those laptops? Let's have a drum roll:
60% have Windows VISTA
26% have Mac OS X
12% have Windows XP
and, 2% or less have something else - like Linux.
This is why I really, really, want good web-based applications.
Just for the record, I don't care what operating systems students use. My concern how to help them use those computers to…
sporte | March 17, 2008Bio-Link is accepting applications for this year's National Summer Fellows forum, June 2-6th, in Berkeley, CA.
You can get an application at www.bio-link.org
I'll be there, doing some kind of bioinformatics workshop. I'll probably be talking about either metagenomics or comparing protein structures and drug resistance, but if you have topic requests, feel free to submit them in the comments.
