drorzel | March 29, 2008Over at Evolving Thoughts, John Wilkins pokes string theorists:
Ernst Rutherford, the "father" of nuclear physics, once airily declared "In science there is only physics. All the rest is stamp collecting". By this he meant that the theory of physics is the only significant thing in science. Such mundane activities as taxonomy in biology were just sampling contingent examples of physics.
So it is with some amusement that I note that in order to make sense of string theory, a group of physicists have been trying to do taxonomy over string theories.
I'm never sure who reads what blogs, but I…
jrosenhouse | March 28, 2008The big Monty Hall book is rapidly coming together. I may even have the first draft done in the next few weeks. It's certainly been a lot more work than I expected when I began. Originally I envisioned a straight math book, where each chapter would present a different variation of the problem followed by a discussion of the sorts of mathematics needed to solve it. To a large extent it is still that, but I was a bit taken aback by the sheer quantity of academic literature that has been produced on the subject. My bibliography is likely to contain more than a hundred items. A discussion…
jrosenhouse | March 28, 2008If you are not already familiar with Oxford's series of Very Short Introductions, I recommend having a look. I've read about two dozen of them to this point and have found them to be consistently excellent.
I've just finished reading the volume on Quantum Theory, written by John Polkinghorne. I especially liked his concluding two paragraphs, where in the space of a few sentences he says all that is important in dealing with the woo-meisters who use the subject for their own New Agey ends:
It seems appropriate to close this chapter with an intellectual health warning. Quantum theory is…
grrlscientist | March 28, 2008tags: LBJ Journal, avian life: literary arts, nature, poetry, birds, birding
I have no connection whatsoever to this new journal, but my friend, professor of poetry at KSU, Elizabeth Dodd, told me about it last night, and I am very very excited about it.
There is a new biannual journal that is dedicated to birds and creative writing, The LBJ: Avian Life, Literary Arts. Those of you who are birders will recognize the title of this new journal, LBJ, as the birders' acronym for "little brown job" -- a name applied to that group of small brown birds that move quickly and are difficult to…

Rhipicera femorata
Victoria, AustraliaÂ
Here's an insect with exceptional reception: Rhipicera, an Australian Dascilloid beetle. Little is known about the biology of this species, but its North American cousins in the genus Sandalus are Cicada parasites- and there are certainly plenty of Cicadas down under.

esiegel | March 26, 2008WARNING: Sensationalism ahead! Are you kidding me, Newsweek? They really titled their article Will Physicists Find God? Presumably, the title is named because physicists are searching for the Higgs Particle, and the title is taken after Leon Lederman's (mediocre, IMO) book, The God Particle. Leon's a pretty humorous guy, and was told by his Editor (according to him, anyway) that he couldn't name his book, "The Goddamned Particle," which is what he called the Higgs, so he shortened it.
For better or worse, the article is an interview with Steven Weinberg, one of the most illustrous living…

The famous Cambrian Explosion- a rapid diversification of animal groups about 550 million years ago- assumes a rather diminished significance when mapped to the full Tree of Life.
update: yes, I made the diagram myself, by modifying this.

from Darwin's Natural Heir
Directed by David Dugan; produced by Neil Patterson
I am a specialized advocate: an advocate for the rest of life. I hope that doesn't sound pompous, but all of us should be advocates for the rest of life. -E.O. Wilson
Last Tuesday I visited the National Geographic Society for the premiere of "Darwin's Natural Heir," a documentary by Neil Patterson about the career and life of naturalist Edward O. Wilson. It's a nice little film, with some effective graphics and visual metaphors, and a good dose of humor. But I wasn't there to see the film. I was there to meet E.…

Mycocepurus smithi, in the fungus garden
An exciting week for ant aficionados! A new study by ant phylogenetics gurus Ted Schultz and Seán Brady provides the first detailed picture of attine evolution. These New World ants have long attracted the attention of biologists because they, like our own species, practice a well-developed form of agriculture. Instead of plants, these ants grow fungi, and their relationship is so specialized that the ants can consume nothing else. Schultz and Brady use data from four nuclear genes, the fossil record, and the biology of extant ants to infer an…
pharyngula | March 25, 2008What an honor: Jeff Medkeff, an astronomer and discoverer of asteroids, has been generous to name a recently discovered set of distant rocks after Michael Stackpole, Rebecca Watson, Phil Plait, and me. That's right, there is now a few billion tons of rock and metal spinning overhead with my name on it, asteroid 153298 Paulmyers. You can find a picture of its orbit and location, just in case you want to visit.
Now I don't know much about astronomy — I know this rock doesn't have any squid on it, unfortunately, and that it's small, cold, and remote (hey, just like where I am now! Only more so…
drorzel | March 25, 2008EurekAlert provides the latest dispatch from the class war, the the form of a release headlined " Family wealth may explain differences in test scores in school-age children":
The researchers found a marked disparity in family wealth between Black and White families with young children, with White families owning more than 10 times as many assets as Black families. The study found that family wealth had a stronger association with cognitive achievement of school-aged children than that of preschoolers, and a stronger association with school-aged children's math than with their reading scores…

Tribolium castaneum - Red Flour Beetle
The genome of the red flour beetle Tribolium castaneum was published today in Nature. This latest insect genome is interesting not for what it says about beetles but for what it says about another model species, the venerable fruit fly. The more we learn about other insect genomes- the honeybee, the mosquito, and now the flour beetle- the more we see that the famed Drosophila fruit fly is an odd little beast. The bee and now the beetle, it turns out, are both rather normal. They share a lot of proteins with mammals, and fish, and other animals we…
oracknows | March 24, 2008I really didn't want to get involved with the whole "framing" debate again. For whatever reason (and they are reasons that I've failed to understand), the very mention of the word seems to set certain members of the ScienceBlogs collective into rabid fits of vicious invective that leave rational discourse behind. And, yes, I know that by saying that I risk setting myself up as a target of said invective, but I don't care. It must be the natural cantankerousness that my low level death crud is inducing in me or maybe it's a lack of judgment brought on by large doses decongestants and…
oracknows | March 23, 2008...because Boston skeptics get to have all the fun with a meeting of Skeptics in the Pub on Monday, March 24 at The Asgard (great name for a pub!) in Cambridge at 7 PM. Keynote speaker for the night is our very own Mike the Mad Biologist. We've done a little blog tag-teaming in the past of some idiotic arguments by creationists claiming that evolution is unnecessary to understand the development of antibiotic resistance in bacteria; so it's a shame I don't live in Boston.
Oh, well. One of these days I need to find out if there's a skeptics' group in my neck of the woods.
pontiff | March 22, 2008I always thought that I was special because I have, in my short life, been kicked into a night club. But now, comes word of an even more spectacular event: scienceblogs' own PZ Myers was expelled from seeing the creationist propoganda film "Expelled!" Adding to the irony, noted biologist/athiest Richard Dawkins, who is famous enough to appear as a character on "Southpark" and who was PZ's guest, was allowed to view the movie! Holy craptacular convergence of ironies, batman!
For those who haven't been following the story, "Expelled!" is a creationist propoganda film narrated by Ben Stein.…
catdynamics | March 20, 2008NOAA provides a River Watch web site - it includes tentative estimates for future precipitation forecast in its estimates, so the long range forecast is uncertain
Right now, because of rains and melting snow, the Ohio and Missouri have bad localized flooding - as this water moves south, the lower Mississippi will rise, but the wave of water also disperses and buffers.
Right now, the lower Mississippi is looking at hitting flood stage, but if rain stays at the level forecast, New Orleans, for example, will not flood. This is in part because the upper Mississippi is not flooding - too cold up…
pontiff | March 20, 2008A New York Times article has appeared about a study on the effects of excessive beer drinking on scientific productivity. The study, (Tomas Grim, "A possible role of social activity to explain differences in publication output among ecologists." Oikos 117 (4), 484-487) done by the aptly named ecologist, Dr. Thomas Grim, claimed that scientific productivity among Czech avian ecologists and behavioral ecologists (as measured by number of publications, citation rate per paper, etc.) dropped according to how many beers the ecologists drank.
Now first of all, I find it kind of annoying that the…

The Harvard multimedia team that put together that pretty video of the Inner Life of the Cell has a whole collection of videos online (including Inner Life with a good narration.) Go watch the one titled F1-F0 ATPase; it's a beautiful example of a highly efficient molecular motor, and it's the kind of thing the creationists go ga-ga over. It's complex, and it does the same rotary motion that the bacterial flagellum does; it has a little turbine in the membrane, a stream of protons drives rotation of an axle, and the movement of that axle drives conformation changes in the surrounding protein…
drorzel | March 20, 2008The coolest-sounding science news of the moment is undoubtedly "Hubble Finds First Organic Molecule on an Exoplanet""
NASA's Hubble Space Telescope (HST) has made the first detection ever of an organic molecule in the atmosphere of a Jupiter-sized planet orbiting another star. This breakthrough is an important step in eventually identifying signs of life on a planet outside our solar system.
Of course, that sounds a little more dramatic and impressive than the reality: they used absorption spectroscopy of the plent's atmosphere to detect the presence of methane in its atmosphere. Now,…
