Books to the ceiling,
Books to the sky,
My piles of books are a mile high.
How I love them! How I need them!
I'll have a long beard by the time I read them.
~ Arnold Lobel [1933-1987] author of many popular children's books.
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…
mikethemadbiologist | March 28, 2010While I'm away, here's something from the depths of the Mad Biologist's Archives:
By way of ScienceBlogling Razib, I came across this Reason article by Ronald Bailey summarizing the presidential candidates views' on evolution. Bailey highlights two reasons what lack of support for evolution says about a candidate:
The candidate probably is weak on the separation of church and state.
The candidate is unable to rationally assess evidence.
But I think this misses the point entirely: evolution matters because evolutionary biology matters.
Granted this sounds like something Yogi Berra would…

from a different Daily Dish -- 365 petri dishes, by Klari Reis
House of Wisdom, the splendid new blog on Arabic science from Mohammed Yahia, editor of Nature Middle East describes an effort to map the Red Sea's coral reefs with satellite, aerial, adn ship-based technologies. Nice project and a promising new blog.
Brain and Mind
Ritalin works by boosting dopamine levels, says a story in Technology Review, reporting on a paper in Nature Neuroscience. The effect is to enhance not just attention but the speed of learning.
As several tweeters and bloggers have noted, H-Madness is a new group blog…
oracknows | March 26, 2010I have an MD and a PhD. While many people find that to be impressive, personally I've become so inured of it that I certainly don't take note of it much anymore. Certainly, I rarely point it out. So, you may ask, why am I pointing it out this time, even going so far as to start a post with it? The answer is simple. If there was one thing I always thought about having both an MD and a PhD, it's that it should render one more resistant to pseudoscience and woo. I know, I know, maybe I'm being incredibly arrogant or incredibly naive--possibly both--but it was what I thought for a long time, even…
razib | March 24, 2010The complete mitochondrial DNA genome of an unknown hominin from southern Siberia:
With the exception of Neanderthals, from which DNA sequences of numerous individuals have now been determined...the number and genetic relationships of other hominin lineages are largely unknown. Here we report a complete mitochondrial (mt) DNA sequence retrieved from a bone excavated in 2008 in Denisova Cave in the Altai Mountains in southern Siberia. It represents a hitherto unknown type of hominin mtDNA that shares a common ancestor with anatomically modern human and Neanderthal mtDNAs about 1.0 million…
oracknows | March 24, 2010It has often been written on this blog and elsewhere that the mark of a true crank is hatred of the scientific consensus, be it consensus regarding the theory of evolution, the science that says homeopathy is impossible, anthropogenic global warming; various areas of science-based medicine; or the safety and efficacy of vaccines. Perhaps the most famous expression of distrust of a scientific consensus is the famous speech by Michael Crichton, in which he famously said:
Let's be clear: the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science…
emjohnson | March 23, 2010Harvard Medical School physician and researcher J. Wes Ulm has a fascinating paper in the new edition of Democracy: A Journal of Ideas, the quarterly academic periodical put out by Johns Hopkins University. His paper "The Cachet of the Cutthroat" investigates the legacy of ideas that formed the basis of laissez-faire social Darwinism:
Ultimately, Social Darwinism fails in practice because it never succeeded as a theory. It's not even Darwinist-Herbert Spencer, after all, had sketched out its contours even before Darwin published his own work. And when the great naturalist outlined a…
oracknows | March 22, 2010Every so often, real life intrudes on blogging, preventing the creation of fresh Insolence, at least Insolence of the quality that you've come to expect. This is one of those times. So enjoy this bit of Classic Insolence from back in November 2007 and be assured that I'll be back tomorrow. Remember, if you've been reading less than two and a half years, it's new to you, and, even if you have been reading more than two and a half years, it's fun to see how posts like this have aged.
I wish I had thought of this one, but I didn't. However, I never let a little thing like not having thought of…
razib | March 21, 2010I have a short piece up at Comment is Free at The Guardian, The origins of morality do not matter. Its flavor is a bit different from my typical blog posts because the format enforces more brevity, so I decided to try and leverage some analogies. I conclude:
... Our moral consensus is a river whose course shifts across the plain, constrained by the hills thrust upward by biology. Only history knows where the river will flow next, though evolution can hint at the range of possibilities.
On a note related to this piece, I will be posting a review of The Price of Altruism: George Price and the…

Gail Weiswasser at the Discovery channel emailed a few days ago to tell me about TONIGHT's premiere on the Discovery Channel of BBC's LIFE, the 11-part follow up to PLANET EARTH (the most successful natural history documentary of all time). While PLANET EARTH told the story of the natural world through the framework of our planet's ecosystems and regions, LIFE takes us on a more intimate journey, introducing different animal and plant groups, using…

One night of passion and you're filled with a lifetime full of sperm with no need to ever mate again. As sex lives go, it doesn't sound very appealing, but it's what many ants, bees, wasps and termites experience. The queens of these social insects mate in a single "nuptial flight" that lasts for a few hours or days. They store the sperm from their suitors and use it to slowly fertilise their eggs over the rest of their lives. Males have this one and only shot at joining the Mile High Club and they compete fiercely for their chance to inseminate the queen. But even for the victors, the war…

razib | March 17, 2010At least in this case, Troglomorphism, trichobothriotaxy and typhlochactid phylogeny (Scorpiones, Chactoidea): more evidence that troglobitism is not an evolutionary dead-end:
The scorpion family Typhlochactidae Mitchell, 1971 is endemic to eastern Mexico and exclusively troglomorphic. Six of the nine species in the family are hypogean (troglobitic), morphologically specialized for life in the cave environment, whereas three are endogean (humicolous) and comparably less specialized. The family therefore provides a model for testing the hypotheses that ecological specialists (stenotopes)…

Most students use Wikipedia, avoid telling profs about it When I talk to writing classes, someone will usually ask if I use Wikipedia. I tell them, "It's often my first stop -- never my last."
Carl Zimmer has mashed up the data from his clever online survey and brings to us The Science Reader: A Crowd-Sourced Profile. He found that readers are going digital, but not to ebooks, possibly because they still love paper books, and some other good stuff. While Carl's Mac was crunching the data, he peeked Through the Sexual Looking Glass.

razib | March 17, 2010A few weeks ago I commented on the paper about the origin of the small dog phenotype in the Middle East. Now The New York Times has an article on a newer paper, New Finding Puts Origins Of Dogs in Middle East. Here's the conclusion:
Dog domestication and human settlement occurred at the same time, some 15,000 years ago, raising the possibility that dogs may have had a complex impact on the structure of human society. Dogs could have been the sentries that let hunter gatherers settle without fear of surprise attack. They may also have been the first major item of inherited wealth, preceding…

It's rare that I encounter a bit of nonsense that allows me to deploy two of my favorite rhetorical devices. First, it lets me pull out one of my favorite clips from one of my favorite movies, in which the immortal line, "Help! Help! I'm being repressed!" was first uttered. Second, it lets me repeat once again yet another variation of Inigo Montoya's immortal words. It's a two-fer! Not surprisingly, it's courtesy of the anti-vaccine crank blog we've all come to know and love (well, I love it because it has provided me such a target-rich environment for taking on quackery and woo, although I…
