pharyngula | February 2, 2009The NY Times ran an interesting article on sexology a short while ago, focusing on the differences in arousal between men and women. Like any guy, I read it hoping to discover the magic switch that turns women on, but as expected, the message is that female arousal is very, very complicated. This was not a surprise. One of the curious results, though, was that not only do men and women differ in the specificity of stimuli that induce arousal, but women's brains (measured by self-reporting) and women's bodies (measured by plethysmograph) don't agree — vaginal arousal was measured when subjects…
drorzel | February 2, 2009There's a mini media blitz underway promoting Denis Dutton's new book The Art Instinct. He was on the Colbert Report last week, he's reviewed in the Times, and he's featured in this week's Bloggingheads Science Saturday:
While it's kind of entertaining to listen to John Horgan struggling to get a word in edgewise, I'm kind of skeptical about the book. Dutton's argument is that human aesthetics are, contrary to the claims of the academic art establishment, more universal than socially constructed, and can best be understood through evolution. Or, to be more precise, through evolutionary…

Explaining the evolutionary tree of life is always a tricky proposition, as narratives are inherently linear but evolution spirals outwards in countless messy directions at once. To tell a story from the tangled bank requires picking a single thread and following it, yet it is precisely our tendency to follow single threads that causes so much misunderstanding of how evolution works.
Attenborough grapples with the problem using an animation that permeates the video, showing graphically the complexity of an ever dividing tree in the background as he traverses time from ancient to modern. …
pharyngula | February 2, 2009It's a bit too phenomenological, and definitely too animal-centric, but who cares? David Attenborough's tree of life is very pretty and gets the gist of the story of life on earth across.
pharyngula | February 1, 2009Jonathan Wells recently gave a talk in Albuquerque at something called the "Forum on Science, Origins, and Design", a conference about which I can find absolutely nothing on the web. I wasn't there, of course, and I don't get invited to these goofy events anyway, but I did get a copy of Wells' powerpoint presentation from an attendee. It's titled "DNA Does Not Control Embryo Development" — shall we look at it together? It's really a hoot.
Jonathan Wells has been exposed to a little bit of knowledge, just enough for him to regurgitate a few common phrases that are current in the developmental…
pharyngula | February 1, 2009A few of us wild and crazy evo people, including Richard Dawkins, wrote up pieces for an issue of the BBC Focus magazine. You'll find me arguing with Steve Jones about whether evolution has stopped, Richard Lenski is highlighted, and Carl Zimmer makes an appearance. If you've got a flash player, you can read it online right now. It's pretty good stuff, if I do say so myself.

"One cannot have too many good bird books"
--Ralph Hoffmann, Birds of the Pacific States (1927).
The Birdbooker Report is a special weekly report of a wide variety of science, nature and behavior books that currently are, or soon will be available for purchase. This report is written by one of my Seattle birding pals and book collector, Ian "Birdbooker" Paulsen, and is edited by me and published here for your information and enjoyment. Below the fold is this week's issue of The Birdbooker Report which…
pharyngula | January 31, 2009A few people (actually, a lot of people) have written to me asking me to address Kirk Durston's probability argument that supposedly makes evolution impossible. I'd love to. I actually prepared extensively to deal with it, since it's the argument he almost always trots out to debate for intelligent design, but — and this is a key point — Durston didn't discuss this stuff at all! He brought out a few of the slides very late in the debate when there was no time for me to refute them, but otherwise, he was relying entirely on vague arguments about a first cause, accusations of corruption against…

pontiff | January 30, 2009Like many an arrogant kid before me, when I graduate from high school in my podunk hometown (no, it wasn't marshy, and I say podunk with all the warm feelings of a idyllic childhood), I was filled with confidence that I was one of the smartest people I knew. Oh, I'd never say it, and yes I knew I was good mostly at only one small thing, mathematics, but I'm pretty certain looking back that I was a pretty confident ass. As you can well imagine, then, transitioning from my high school to Caltech, an institution filled with near-perfect-SAT-scoring students, Nobel laureate faculty members, and a…
drorzel | January 30, 2009I'm not sure what the BBVA Foundation is, but they've awarded a Basic Science prize to Ignacio Cirac and Peter Zoller:
The Basic Sciences award in this inaugural edition of the BBVA Foundation Frontiers of Knowledge Awards has been shared by physicists Peter Zoller (Austria, 1952) and Ignacio Cirac (Manresa, 1965), "for their fundamental work on quantum information science", in the words of the jury chaired by Theodor W. Hänsch, Nobel Prize in Physics. Zoller and Cirac's research is opening up vital new avenues for the development of quantum computers, immensely more powerful than those we…

The Pigeon of Passage
The Natural History of Carolina, Florida and the Bahama Islands, 1754
Mark Catesby
Unlike Benjamin Button, he's not up for an Oscar, but he's also a film star - several hundred years late. Mark Catesby (1683-1749), a forerunner of Audubon, was the first European scientist/artist to document the flora and fauna of North America. He depicted live specimens in their natural habitats, and made special study of both migration and extinction. You can view Catesby's masterwork, The Natural History of Carolina, Florida and the Bahama Islands, Vol 1 and Vol 2, at the University…

For Christmas, my friend Vanessa got me this wonderful Equal Measure measuring cup by Fred. One side gives measures in cups and ounces, along with the equivalent quantity of various granular substances (five thousand drops of water, as many grains of flour as people on the planet). The other side gives metric volumes, alongside biological volumes (half a human brain; enough corn oil to fuel a biodiesel car for three miles, amount of table salt in a large human).
If I were still teaching physiology, I'd totally be using this in lab! As it is, I may have to convert a recipe or two into T. rex…
drorzel | January 29, 2009As noted in the previous post, I'm supposed to be moderating a panel at Boskone the weekend after next, with the title:
Global Warming: Facts and Myths, (and all that jazz)
This is not my usual line, but then, I don't have to provide expert commentary, I just need to steer the discussion. Still, it would be good to have some idea where to steer it, so I will throw this out to the larger ScienceBlogs community:
What should I make sure to talk about in a panel on global warming facts and myths?
Of course, there are some additional constraints:
1) I'm looking for general discussion topics, not…

Pheidole moerens, major worker, Louisiana
Pheidole moerens is a small, barely noticeable insect that travels about with human commerce, arriving without announcement and slipping quietly into the leaf litter and potted plants about town.  As introduced ants go, P. moerens is timid and innocuous- it's certainly no fire ant. The species is now present in the southeastern United States, a few places along the west coast, and Hawaii. Conventional wisdom suggests that P. moerens originated in the Greater Antilles, but even though the ant was first described from Puerto Rico a century ago…
drorzel | January 29, 2009Boskone, the Boston-area SF convention that Kate and I go to every year, is the weekend after next. Once again, I'll be doing a few panels and one talk. For those who might be attending, or who care about this for some reason, here's my preliminary schedule:

Geoffrey A. Landis

Ian Tregillis
In 1999 John Cramer wrote a column in Analog describing seven big
unsolved problems in physics (including the nature of dark matter,

razib | January 28, 2009Mars Rover Disoriented Somewhat After Glitch:
More strangely, the Spirit had no memory of what it had done for that part of Sol 1800. The rover did not record actions, as it otherwise always does, to the part of its computer memory that retains information even when power is turned off, the so-called nonvolatile memory. "It's almost as if the rover had a bout of amnesia," said John Callas, the project manager for the rovers.
Another rover system did record that power was being drawn from the batteries for an hour and a half. "Meaning the rover is awake doing something," Dr. Callas said. But…
