On Netflix: Cave of Forgotten Dreams

Urglegurgle. I’m trying to prep a lecture on synapse formation, and just discovered that Herzog’s amazing film about Chauvet cave is available…so I’m trying to scribble up technical notes on molecular biology while getting constantly distracted by 32,000 year old cave paintings. It’s good to live in the 21st century, but I think my brain is getting full.

Mad scientists, start drooling

The future is arriving fast. Here are the instructions for assembling a $500 home molecular biology laboratory — you can do it! And it’s getting cheaper all the time!

The widespread and increasing availability of second-hand professional laboratory equipment or inexpensive new commercial surrogates means that it is now unchallenging to set up a fully functional molecular laboratory for less than $500 in equipment costs. Coupled with the presence of sources for all reagents and supplies needed in formats that are safe for general use, the work presented here demonstrates that capacity to set up functional molecular biology teaching modules is well within the reach of even the smallest educational facilities. When coupled with outsourced PCR product Sanger sequencing available from commercial sources at prices approaching $5/reaction, the capacity of such “home labs” to start undertaking research of real potential scientific value—such as surveys of microbial biota in unusual environments—at negligible costs should not be underestimated. Similarly, the potential for setting up labs of this type for medical applications in emerging countries may be worth considering. While current best methods have moved to real-time and array-based high throughput, contamination resistant methods, the methods demonstrated here were “state of the art” for clinical and research molecular diagnostics in the Western world only some 15 years ago.

Hmmm. The kids have flown, I’ve got more space than we know what to do with…maybe this summer I should tinker with setting up something like this.

Anti-caturday post

I used to keep these lovely little guys as pets — they’re so pretty and active, and have such soulful eyes…and so many of them. Their courtship dance is also cool, and so easily evoked; these spiders are always looking for love.

Unfortunately, the species I’ve been able to find in Minnesota are much smaller than the ones I found in Oregon, and the weather greatly limits their availability. If you’re living in warmer climes and haven’t been watching these adorable beasties you’ve been missing out. Especially if you’re keeping cats, instead.

My turn at Skepticon

Yeah, I gave a talk at Skepticon like several other rascals here at Freethoughtblogs. Now, even if you didn’t make the pilgrimage to Springfield, Missouri, you can watch it too.

It’s a straight science talk with several swipes at creationism, so unfortunately, I don’t think it will make any ice cream salesmen cry.

Hamza Tzortzis on the Intellectual Dishonesty of Professor Myers SHOCKING!

That’s what he titles his latest youtube video, anyway. I laughed, just like I laughed when Eric Hovind called to complain about the misinformation on my website. He also claims I “accept defeat”

Myers accepts defeat see below:

Myers changes his stance from Ireland, In Ireland Myers says the ‘Quran is Wrong’. After reviewing the iERA Research Paper he now believes its the Quran has ‘ very little opportunity for disproof, and they can be made to fit just about any reasonable observation.’

I am surprised to learn that I accepted defeat. Doesn’t he know I’m indomitable? Anyway, here’s the video where Tzortzis crushes me.

I will give him credit — he does link to my article debunking Islamic embryology, which is more than most creationists would do. But still, he’s got it all wrong.

During our encounter in Ireland, I pointed out that their specific claim of a discrete sequence of development in the embryo, from bones to muscles being added to bones, was false. In the article I wrote on Tzortzis’s strained exegesis of two verses from the Quran, I explained that you can’t make concrete claims about embryology from such a vague, cursory, and intentionally poetic source, such as those two verses. These are not incompatible arguments. The second point is not a softening of the views made in the first point.

If anything, Tzortzis has backed down. In Ireland, he and his friends were trying desperately to argue that Mohammed knew things that no man in his position could possibly have known without a divine source of information; my argument was that no, what’s in the Quran is very much in line with the knowledge of his day, derived from Aristotle and Galen. No miracles were required to write those two verses.

Now Tzortzis’s claim is greatly reduced; it is that the Quran does not “negate reality”, or does not make claims that contradict known science. That’s fine; as I said, it’s the most minuscule of verses saying the wobbliest things, and it’s derived from observations of embryos made by Greek and Roman predecessors, so it’s not surprising that it can be retrofitted to fit modern science by playing enough word games.

Tzortzis relies on what he calls “lexical analysis”, but it’s little more than compiling the equivalent of thesaurus entries for words in the verses, and then picking and choosing the ones that fit the point he’s trying to make. That’s not analysis, it’s cherry-picking.

Amusingly, he does the same thing to modern developmental biology. He’s gone rifling through legitimate embryology texts, trying to prove that I don’t know what I’m talking about, and he found one sentence in a textbook — “after the cartilaginous models of the bone have been established, the myogenic cells, which have now become myoblasts, aggregate to form the muscle masses” — that he thinks shows I was wrong and that his interpretation of the Quran phrase — “bones were clothed with flesh” — is correct.

Wrong. See, this is the problem with his “lexical analysis” approach — it means he tries to conform what he reads to what he already thinks he knows. I know what a developing limb looks like; mesodermal masses condense gradually into organized clusters of cells that differentiate in parallel. Centers of what will become bones aggregate and form cartilage (not bone, notice) as centers of what will become muscle (the myogenic cells in that description) aggregate and begin differentiation into myoblasts and myotubes and eventually muscle fibers.

Here’s what we actually see in the developing limb: branching patterns of cell fate decisions by tissue precursors, and parallel differentiation of the cellular components of those tissues.

The simplistic and discrete idea of “bones, then flesh” doesn’t even recognize that “bones” and “flesh” aren’t simple binaries, and the sequence isn’t a simple temporal switch. What you had instead was the early segregation of cells into differing mucopolysaccharide matrices, within which cells began complex sequences of shifting patterns of gene expression and differentiation into mesodermally-derived tissues.

Or more poetically, bones and flesh congealed together out of balls of snot. There are sequences within that pattern, but chondrocytes aren’t bones and myoblasts are not muscles. Tzortzis is trying too hard to fit the Quran to science, because he can’t appreciate that it’s just a book written by men trying to make sense of the world, and also unfortunately trying to add extra weight to their opinions by claiming the authority of a god behind them. A sad state of affairs that I’m afraid their modern descendants continue to perpetrate.

Gals and show mares

This video has been going around — it’s a group of women talking about the importance of evolution to the biological sciences.

I confess to cringing in a few places — there’s too much ready equation of evolution with natural selection — but I certainly wouldn’t question the competence of these accomplished scientists, even if I might argue with them a bit.

But now the clowns at Uncommon Descent have discovered it and given their assessment.

It shows sixteen female academics or science writers, mostly young, whose enthusiasm for evolution is so overwrought that they turn themselves into propagandists.

Eager to show how well they have been trained, they are like show mares who trot around the paddock jumping over each gate in turn. All the while they give the camera a look that says: “Aren’t I good?”

And then the conclusion:

Here, we’d wondered who would be the next Lynn Margulis. Our scouts can now save time by crossing these gals off.

“Gals”? Really? And since when do creationist hacks get to cross “gals” off the rolls of worthy scientists?

That’s right there in the article. There is worse in the comments; I know the site isn’t entirely responsible for what commenters say, but this is from one widely known freakish creationist who agrees with the sentiment in the article, that these women won’t cut it as real scientists. (There are also others that disagree with this guy; no one seems to have noted the patronizing attitude of the article itself.)

There is however a liberal establishment with a agenda to promote women and this means over more deserving men. Affirmative action , openly/secret, is powerful in nOrth america.
They want women to be as smart as men in these perceived smarter things.
They think it should be at least 50/50.
However it ain’t and it never will.
