Whatever you do, don’t let her answer the red phone.
The Texas Board of Education has named the six people who will be on a committee to review science curriculum standards. Texas, you’ve got trouble. The people are:
David Hillis, professor of integrative biology and director of the Center of Computational Biology and Bioinformatics at the University of Texas at Austin;
Ronald K. Wetherington, professor of anthropology at Southern Methodist University and director of the Center for Teaching Excellence;
Gerald Skoog, professor and dean emeritus of the College of Education at Texas Tech and co-director of the Center for Integration of Science Education and Research;
Stephen Meyer, vice-frakkin’-president of the odious Discovery Institute in Washington state;
Ralph Seelke, a pro-ID creationist and biologist from Wisconsin;
Charles Garner, a chemist from Baylor who is also a pro-ID creationist.
Note that Meyer and Seelke are co-authors of that ghastly new ID textbook, Explore Evolution, and would no doubt love to tweak the curriculum to make their book marketable in Texas. Conflict of interest? Nah.
So, three good guys and three ignorant ideologues, with the overall head of the board of education being Don McLeroy, the creationist dentist. It’s going to get ugly.
My colleague at the Twin Cities branch campus of the University of Minnesota, Randy Moore, has won an award from the Discovery Institute: The Award for Most Dogmatic Indoctrinator in an Evolutionary Biology Course. Congratulations to Randy! He won it for this paragraph:
The evidence supporting evolution is overwhelming and comes from diverse disciplines, such as molecular biology, paleontology, comparative anatomy, ethology, and biochemistry. There is no controversy among biologists about whether evolution occurs, nor are there science-based alternative theories. Evolution is a unifying theme in biology; teaching it as such is the best way to show students what biology is about and how they can use evolution as a tool to understand our world. [Evolution] is as important an idea as there is in science – it is a great gift to give to students.
The Discovery Institute claims there are at least four mistakes in that paragraph. Their summary of the “errors” is hilarious, and shows how delusional those guys are.
The evidence isn’t overwhelming, because their books, Icons of Evolution and Explore Evolution, say so. Those two books are propaganda pieces put out by the Discovery Institute itself, and they are awful: poor scholarship, sloppy reasoning, and and an abysmal ignorance of the science characterize both. If you want some good popular books on the subject, try The Making of the Fittest(amzn/b&n/abe/pwll), Your Inner Fish(amzn/b&n/abe/pwll), Why Evolution is True(amzn/b&n/abe/pwll), and The Ancestor’s Tale(amzn/b&n/abe/pwll), all much better and more informative, and actually representing the evidence accurately.
There is too controversy because they have a list of crackpots dissenters from evolution. Any field will have kooks and crackpots on the fringe; compiling a short list of loons is a relatively trivial and entirely meaningless exercise. Even at that, the DI’s list is very short on people who are actually biologists…and the whole petition is misleadingly worded.
Evolution is a theory in trouble because some scientists discussed alternative modes of evolution at the Altenberg conference this summer. Science is not fixed, but adapts to the evidence, so it is perfectly normal to have conferences that discuss new ideas. The Altenberg meeting did not challenge the fact of evolution or try to displace known evolutionary mechanisms; it discussed some new findings that might add to the theory. It’s absurd that people are still going on and on about how a small meeting of scientists working on extending some parts evolutionary theory is a strike against evolution. To the contrary, it’s what we expect of good science.
There are too science-based alternative theories: Intelligent Design, endosymbiosis, and self-organization. Margulis’s endosymbiotic theory was a natural explanation for eukaryote evolution — it is not an alternative, but a part of evolutionary theory. Similarly, self-organization (as, for example, described by Kauffman) does not oppose evolution at all, but suggests that physical and chemical properties of the universe could facilitate evolution. Like I said above, these are part of the normal process of science, that people propose new explanations and try to back them up with evidence, and they become incorporated into our body of knowledge. Intelligent Design creationism does not qualify. IDists don’t do science, don’t propose testable theories, and don’t have any evidence to back up their claims.
So I hope Randy Moore doesn’t get too cocky here — the award was given by a gang of incompetent judges who don’t know what they are talking about.
OK, this is the kind of thing that just pisses me off: the tendency for some liberals to go off all loopy and credulous. The perfect example is on Salon right now—an article that goes on at ridiculous length about the judgments of a physiognomist, a ditz who derives McCain’s economic policy from the shape of his nostrils, and Obama’s idealism from the breadth of his forehead. This is insane, and irritating, and stupid.
The one thing I dread with a Democratic victory is the ascendancy of navel-gazing crystal-healing New Age loons, without a shred of critical thinking.
I have to give gogreen18 a godless clenched fist salute for this passionate explanation for why atheists need to speak out.

How can I respond to a story about zebrafish, development, and new imaging and visualization techniques? Total incoherent nerdgasm is how.
Keller et al. are using a technique called digital scanned laser light sheet fluorescence microscopy (DSLM) to do fast, high-resolution, 3-D scans through developing embryos over time; using a GFP-histone fusion protein marker, they localize the nucleus of every single cell in the embryo. Some of the geeky specs:
1500×1500 pixel 2-D resolution
12 bits per pixel dynamic range
Imaging speed of 10 million voxels per second
Complete scan of a 1 cubic millimeter volume in 3µm steps in 90 seconds
Efficient excitation (5600 times less energy than a confocal, one million times less than a two-photon scope) to minimize bleaching and photodamage
Trust me, this is great stuff — as someone who was trying to do crude imaging of fluorescently labeled cells in the 1980s using a standard fluorescence scope and storing stills on VHS tape, this is all very Buck Rogers. Just load your embryo into the machine, start up the scanner, and it sits there collecting gigabytes of data for you for hours and hours.
But wait! That’s not all! They’ve also got sophisticated analysis tools that go through the collected images and put together data projections for you. For instance, it will color code cells by how fast they are migrating, or will count cell divisions. Similar tools have been available for C. elegans for a while now, but they have an advantage: they’re tiny animals where you might have to follow a thousand cells to get the full story. In zebrafish, you need to track tens of thousands of cells to capture all the details of a developmental event. This gadget can do it.
Here, for instance, are a couple of images to show what it looks like. The right half is the raw embryo, where each bright spot is a single cell nucleus; the left is one where the pattern of cell movement is color-coded, making it easier to spot exactly what domains of cells are doing.

I grabbed one of their movies and threw it on YouTube for the bandwidth-challenged. It’s not very pretty, but that’s the fault of reducing it and compressing it with YouTube’s standard tools. This is an example with color-coded migration (blue cells are relatively motionless, orange ones are moving fast), and you can at least get the gist of what you can detect. You can see the early scrambling of cells in the blastula, migration during epiboly and blastopore closure, and convergence in the formation of the body axis fairly easily. Well, you can if you’re familiar with fish embryology, anyway.
This crappy little video doesn’t do it justice, however. Take a look at the Zebrafish Digital Embryo movie repository for much higher resolution images that are crisp and sharp and unmarred by compression artifacts. It contains DivX and Quicktime movies that are somewhat large, 10-40M typically, that represent visualizations of databases that are several hundred megabytes in size.
What can you do with it? They describe observations of early symmetry breaking events; patterns of synchrony and symmetry in cell divisions; direct observations of the formation of specific tissues; and comparisons with mutant embryos that reveal differences in cell assortment. It’s fabulous work, and I think I’m going to be wishing for a bank of big computers and lasers and scopes for Christmas—only about $100,000 cheap! Until then, get a fast internet connection and browse through the movies.

Ignorance leads to evil: albinos are being butchered for their body parts in Burundi. Witch doctors are spreading the claim that their body parts are valuable in attracting gold, so stupid and greedy people are killing them and selling off bits and pieces.
Officials have gathered all the albinos in the country into a walled safehouse to protect them, which seems like a short term solution. I say since their number came up in the genetic lottery as cursed in Burundi, offer them asylum and bring them to Minnesota, where their paleness won’t be at all exceptional.
Say…wasn’t an African witch doctor one of Sarah Palin’s heroes? Let’s be sure not to bring them to Alaska, then.
Seed and Scientists and Engineers for America are teaming up to promote a youtube challenge — they are collecting videos of scientists stating who they are voting for in the coming election. The first one up is Marty Chalfie, winner of the Nobel in Chemistry this year. Guess who he thinks should be president?
I suspect that the scientific establishment will be showing a profound liberal bias this year, largely because the scientific establishment tends to be pro-reality.
You don’t have to be a Nobelist — if you’re a scientist, record a youtube video of yourself, tag it with “aVoteForScience”, and you too can contribute.
Wait until the wingnuts get this: Hindus are presenting Obama with a monkey-god idol.
The idol is being presented to Obama as he is reported to be a Lord Hanuman devotee and carries with him a locket of the monkey god along with other good luck charms. An hour-long prayer meeting to sanctify the idol was earlier organised at Sankat Mochan Dham and by Congress leader Brijmohan Bhama, Balmiki Samaj and the temple’s priests. “Obama has deep faith in Lord Hanuman and that is why we are presenting an idol of Hanuman to him,” said Bhama.
And in other news, we have a lovely brass statue of the Buddha at our house, which I guess makes me a Buddhist, and we also have a stuffed cobra, which makes us Satanists. And we have a Bible or two, and a copy of the Koran, and somewhere I have a copy of some very pretty and colorful book the Hare Krishnas handed to me in an airport once. Since I also own a complete set of DVDs for both Buffy and Firefly, I must also be a devout Whedonist. I guess Obama and I have a plurality of gods to go up against the blinkered and benighted monotheists, then.
