tetrapodzoology | July 6, 2009I'm really suffering from lack of time, so here's another book review (first published in 2005, so with a few updates added here and there)...
Lacking the Mesozoic dinosaur record of Britain, France, Germany, Portugal or Spain, our Italian colleagues have long had to make do with Triassic marine reptiles, Cretaceous squamates, and assorted Neogene mammals... not that there's anything wrong with that of course. Three interesting new dinosaur taxa, and a host of footprint discoveries, have changed all that however, and today Italy clearly has something quite important to say about the…

One of Buckminster Fuller's most interesting conceits was his dislike of specialization, which he likened to a kind of intellectual prison, restraining "bright" people from truly understanding the complex, and general, systems of which they were a part. After all, he argued, what causes extinction in the animal kingdom? Overspecialization. Of course, it's logical, and it's s problem we see over and over again in human history, from the Industrial Revolution displacing specialized factory workers to the often daunting gap of comprehension between the social and "hard" sciences. As soon as we…
clock | July 5, 2009As we mentioned just the other day, studying animal behavior is tough as "animals do whatever they darned please". Thus, making sure that everything is controlled for in an experimental setup is of paramount importance. Furthermore, for the studies to be replicable in other labs, it is always a good idea for experimental setups to be standardized. Even that is often not enough. I do not have access to Science but you may all recall a paper from several years ago in which two labs tried to simultaneously perform exactly the same experiment in mice, using all the standard equipment, exactly…
edyong | July 5, 2009Rising temperatures and high carbon dioxide emissions are the means through which humans are inadvertently causing the decline of several species. But one animal actively uses both heat and carbon dioxide as murderous weapons - the unassuming honeybee.
With their stings and numbers, bees already seem to be well-defended but they are completely outgunned by giant hornets (right). These two-inch long monsters are three times longer than several times heavier than tiny honeybees and raiding parties can decimate entire hives. European bees mount little in the way of an effective defence, but…
clock | July 4, 2009Thursday morning was the Biofluorescence morning, with lectures by the three most recent Nobelists who received their prize for the discovery and first uses of the Green Fluorescent Protein (GFP) and its derivatives that glow in other colors. It's hard to think of an animal that is as non-model in the lab as jellyfish and a discovery as important and useful for modern biological research.
Unlike PZ who was a diligent liveblogger in the conference hall, I watched all three lectures from the press room, livestreamed on my laptop, while multitasking and generally enjoying the perks of being "…
neurophilosophy | July 3, 2009THE human brain is a true marvel of nature. This jelly-like 1.5kg mass inside our skulls, containing hundreds of billions of cells which between them form something like a quadrillion connections, is responsible for our every action, emotion and thought.
How did this remarkable and extraordinarily complex structure evolve? This question poses a huge challenge to researchers; brain evolution surely involved thousands of discrete, incremental steps, which occurred in the mists of deep time across hundreds of millions of years, and which we are unlikely to ever fully understand.
Nevertheless,…
tetrapodzoology | July 3, 2009The recent discovery that some Asian microhylid frogs frequent the dung piles of elephants has gotten these obscure little anurans into the news, possibly for the first time ever. Microhylids - or narrow-mouthed frogs - are not exactly the superstars of the frog world: they're only really familiar to specialists, despite the fact that (as of June 2009) they contain over 450 species distributed across Africa, Madagascar, the Americas, and Asia. However, some more recent research on the group shows that, like so many animals, they're really quite interesting once you get to know them...
You…

Giant Dinosaurs of the Jurassic is a children's book for kids in third to fifth grade or, in my opinion, a little younger. Certainly this is an excellent choice, because of the cool illustrations, of a book to read aloud to the pre-literate little ones.
Author Gregory Wenzel does a good job in few words explaining life in the Jurassic, how bones get to become fossils, and something about how they are found. Most of the riveting several hundred words in this 32 page book are about the real stars of the show, the dinosaurs themselves.
Not every single dinosaur in this…
pontiff | July 1, 2009Over at my old blog one thread which keeps on giving is my missive about Dr. Wayne Dyer which now has over 2000 comments. I can always tell when it's PBS pledge drive time by the bump in traffic on my old website and the increase in comments on this post. Today I got a spam comment on the post. Now usually spam comments aren't to exciting (bad Viagra joke deleted), but this one is...well...different.

pharyngula | June 30, 2009The old fossil is Pat Buchanan, who has published a freakishly antiquated diatribe against Darwin. It's extremely old school — he uses arguments straight out of 1960s era "scientific creationism", trying to tar Darwin with guilt by association with Karl Marx and Adolf Hitler. He is apparently inspired by a "splendid little book," The End of Darwinism: And How a Flawed and Disastrous Theory Was Stolen and Sold, by a creationist crank named Eugene G. Windchy. You can get an idea of Windchy's level of scholarship by this quote:
That Darwinism has proven "disastrous theory" is indisputable.

clock | June 30, 2009Just because I am galivanting in Lindau does not mean I could not take a look at the brand new papers published in PLoS ONE, PLoS Biology, PLoS Medicine and PLoS Neglected Tropical Diseases last night. A few titles caught my eye - take a look. As always, you should rate the articles, post notes and comments and send trackbacks when you blog about the papers. You can now also easily place articles on various social services (CiteULike, Mendeley, Connotea, Stumbleupon, Facebook and Digg) with just one click. Here are my own picks for the week - you go and look for your own favourites:…

Since the early 20th century, at least, young earth creationists have attempted to blame Charles Darwin for genocide, world wars, and whatever political movements seemed most threatening at one time or another (i.e. communism). What Darwin is faulted with changes with the times, but most recently young earth creationists have focused on hot topics from Darwin's own era: racism and slavery. From the Answers in Genesis tract Darwin's Plantation to the upcoming (and unethically produced) documentary The Voyage That Shook the World,…

Birds in Science
One of the fifteen Frisian 'transmitter godwits', which was still in Friesland on one week ago on Saturday, arrived in Senegal in West Africa on Tuesday morning. The bird, nicknamed Heidenskip, appears to have flown from Friesland via Spain and over the Sahara in one go. The distance, over…

... is certainly still in the future. But we have seen a step in that direction in a new paper, coming out this week in Science. This research applies intensive and extensive genomic analysis to the avian phylogenetic tree. The results are interesting.
This paper is summarized in a number of locations, most notably here on Living the Scientific Life. Here, I will summarize it only very briefly. However, there are two observations I would like to make about this paper and its apparent meaning. One has to do with the nature of science, and the other has to do with…
pharyngula | June 25, 2009Last week, I received an ominous email from Stuart Pivar.
Dear PZ,
The work of my lab has been subject to questions and harsh criticisms, some reasonable, some not. The scientific ones are dealt with in a new book On The Origin Of Form, Evolution by Self-Organization, an alternative to the natural selection paradigm, This is a substantially expanded presentation of the self-organization model previously published.
I welcome your assessment. If you are convinced now of its plausibility, as are many others, I solicit your participation in the dissemination of the idea for further…

pharyngula | June 24, 2009He seems a bit peevish. He now has a blog post up complaining about me and my "inaccuracies". His complaints are amusingly petty.
I object to the lies at the very heart of his "museum", and he thinks he is rebutting me by whining over petty details.
For instance, he quotes me as regarding the idea of "Noah's ark being built to carry off members of every species on earth", and then he primly informs his readers that that isn't true: it only carried every kind of "land-dwelling, air-breathing animal". Oh, well, that fixes the logistical problems of the ark right up, doesn't it? Here we have a…

Beating The Bullies: Changing Real-world Behavior Through Virtual Experience:
Social problems like bullying and stereotyping involve thoughts, feelings and reactions that resist change. New research shows that when students play active roles in virtual dramas their attitudes and behaviour can change.
How Big A Role Does Chance Play In The History Of Life?:
If the broad evolutionary diversification of a group of organisms were repeated by a few species in a single genus tens of millions of years after the group's initial diversification, what would that say about the roles of contingency,…

The photo of the Northern ground hornbill Bucorvus abyssinicus featured here yesterday was posted entirely on a whim. And I figured that I didn't need to say much about the species, nor about ground hornbills in general, given that they've been discussed at length on Tet Zoo before. But then I realised that the only in-depth treatment of ground hornbills at Tet Zoo comes from ver 1, and thus dates to 2006. That's three years ago. Given that so much has changed in terms of Tet Zoo's readership, it's clearly time to re-post this old, classic article. If you remember it from the first time…
