Hey, everyone! The new ScienceBlogs main page has been launched, and the Seed nerd-kings have added a whole new crop of blogs here. Take a browse, you might discover some new favorites.
After the recent struggles trying to keep up with the traffic on this site, you wouldn’t think I’d feel compelled to go trolling for more visitors, but isn’t that the nature of weblogging? The only point to it all is to rack up a bigger score than the next guy, as if we were playing pinball. So what’s a good ploy? As Lauren has cleverly pointed out, sex sells. And while it may be estrogen week, I’m going to buck the trend, since we all know what’s really important for weblog popularity: penises.
The fugu is a famous fish, at least as a Japanese sushi dish containing a potentially lethal neurotoxin that was featured on an episode of The Simpsons. Fugu is a member of the pufferfish group, which have another claim to fame: an extremely small genome, roughly a tenth the size of that of other vertebrates. The genome of several species of pufferfish is being sequenced, and the latest issue of Nature announces the completion of a draft sequence for the green spotted pufferfish, Tetraodon nigroviridis, a small freshwater species.
Creationists are fond of the “it can’t happen” argument: they like to point to things like the complexity of the eye or intricate cell lineages and invent bogus rules like “irreducible complexity” so they can claim evolution is impossible. In particular, it’s easy for them to take any single organism in isolation and go oooh, aaah over its elaborate detail, and then segue into the argument from personal incredulity.
Last night, I had to read this book RPM mentioned. It’s not very long—about 100 pages, counting a preface, an epilogue, and an afterward, and it has lots of pictures—but be warned: it’s very inside baseball.
The book is Won for All: How the Drosophila Genome Was Sequenced(amzn/b&n/abe/pwll) by Michael Ashburner, and its subject is the rush to sequence the Drosophila genome in 1998-1999. It’s a rather strange twist on what I expected, though. While the subtitle says “How the Drosophila Genome Was Sequenced,” there is almost no science at all in the body of the book; instead, it’s all about the people and the politics, with Ashburner flitting about from place to place, yelling at people and eating sushi. It’s phenomenally entertaining.
Let me tell you about this Achilles tendinitis I’ve got.
My first couple of steps in the morning are flaming agony. After working it and gingerly stretching for a while, it subsides to a dull ache, and I’m good for about a half hour of cautious hobbling. After that, though, the pain builds and builds, until it’s like slamming my heel down on a white hot knife.
I’m not saying this because I’m fishing for sympathy. I spent over an hour and a half today limping through the Darwin exhibit at the AMNH. The pain I suffered through tells you a) how stupid I am to overdo it (I’m paying for it now, I tell you) and b) how good that exhibit is.
It follows the development of Darwin’s thought and demonstrates the evidence that led to his conclusions. It is completely uncompromising. It makes a few nods to the modern evidence at the end, and does mention the creationist objections briefly, as the nonsense they are…but it’s amazing how solidly the case can be made for evolution using just the 19th century data.
And then, or course, there are the artifacts. Darwin’s microscope. Annie’s box(amzn/b&n/abe/pwll). Bits of his notebooks. Darwin’s walking stick. It was glorious stuff.
I strongly recommend it. Even if the exhibit is also full of psychopathic badgers with acid-dripping claws ripping at your ankles. It’s really worth it.
Since Evolgen recognizes the importance of evo-devo, I’ll return the favor: bioinformatics is going to be critical to the evo-devo research program, which to date has emphasized the “devo” part with much work on model systems, but is going to put increasing demands on comparative molecular information from genomics and bioinformatics to fulfill the promise of the “evo” part. I’m sitting on a plane flying east, and to pass the time I’ve been reading a very nice review of the concept of modularity in evo-devo by Paula Mabee (also a fish developmental biologist, and also working in a small college in a small town in the midwest…but rather deservedly better known than yours truly). In addition to summarizing the importance of the concept of modularity to evolution and development, the paper also does something I always appreciate: it summarizes the key questions that the modern evo-devo research program is working to answer.
The Art of Science exhibition has many lovely pictures in the galleries, but I think my favorite is this image of Nodal expression in zebrafish.
After writing about the dilution of those “dangerous” kids’ chemistry sets, I find that Nature has just published a news article wondering how dangerous chemistry actually is.
