A photograph and line drawing (left side) of the fossil dolphin Astadelphis gastaldii. The crescent-shaped line in the line drawing represents the bite of a large shark, with the red portions representing damage done directly to the bone. From Bianucci et al, 2010.
Shark attacks are events of speed and violence. When they have locked on to a prey item sharks seem to come out of nowhere, and though they can be quite gentle with their jaws (as on occasions when they are unsure about whether something is food or not) their ranks of serrated teeth can inflict a devastating amount of damage.…

Earlier this week I discussed how to find a publisher for your book and how blogs can be useful tools in that process, but what about the effort that goes into completing a manuscript?
As Michael has pointed out in his latest blog-length contribution to our conversation, every writer is different. How Michael approached writing Sand was very different from how I went about composing Written in Stone, so rather than try to lay out a precise set of writing rules I will attempt to summarize my unique writing experience.
By the time I signed with Bellevue Literary Press in the autumn of 2009…

Blogs, as Carl Zimmer astutely noted at this year's ScienceOnline conference, are software. Despite all the hand-wringing over whether science bloggers can or should replace science journalists the fact of the matter is that science blogs are the independent expressions of a variety of writers about subjects which they feel passionate about. There is no single science blog archetype that all blogs must fit, and this flexibility allows science writers the freedom to compose and promote their work in an increasingly fragmented media landscape.
Hindsight being what it is, of course, I can look…

Writing a popular science book has simultaneously been the most challenging and rewarding experience of my writing career so far. It was not so much something that I wanted to do as a task that I needed to do, and without that sense of resolve Written in Stone would probably be a half-finished manuscript left to rot on my hard drive. While hard-headed persistence has been essential to writing my book, though, it was not the only thing I required, and through this blog conversation with David Williams (author of Stories in Stone; blog) and Michael Welland (author of Sand; blog) I hope to…

laelaps | March 13, 2010I love the work that Larry Witmer and his students do at Ohio University. Not only is it cutting-edge anatomical research that helps us better understand prehistoric organisms, but the Witmer lab is constantly sharing parts of their work via the web. They even have their own YouTube feed with lots of 3D renderings of fossil animals, including one of my favorite prehistoric mammals, Archaeotherium. The video below presents a view of its skull and brain cast, as well as a quick look at its jaws in action:

When it comes to aliens, Hollywood really does not have much imagination. Most extraterrestrials that have appeared on the big screen look very much like us, or are at least some kind of four-to-six-limbed vertebrate, and this says more about out own vanity than anything else. It would be far more interesting, I think, to take the weird and wonderful organisms of the Cambrian as inspiration for alien life forms, and two new critters have just been added to the odd Cambrian menagerie.

I couldn't say why, but I have never been very interested in stories about vampires. I have never read Dracula, I have no interest in Buffy the Vampire Slayer or True Blood, and I think Twilight is some of the worst literary and movie cheese to come out in a while, but despite my general apathy for tales of bloodsuckers I was intrigued by Mark Collins Jenkins' new book Vampire Forensics: Uncovering the Origins of an Enduring Legend. From the synopsis is seemed like a mix of history, science, and mythology that I could really sink my teeth into.
As it turned out, Vampire Forensics was not…

Of all the mass extinctions that have occurred during earth's history, among the most hotly debated is the one which wiped out mammoths, saber-toothed cats, giant ground sloths, and the other peculiar members of the Pleistocene megafauna around 12,000 years ago. It was not the most severe mass extinction, not by a long shot, but unlike the end-Cretaceous catastrophe 65 million years ago there is no single "smoking gun" that can account for the pattern of extinction. Instead the Pleistocene mass extinction…

A simplified evolutionary tree of primate relationships showing the placement of Darwinius in relationship to other groups. From Williams et al., 2010.
The study of human origins can be a paradoxical thing. We know that we evolved from ancestral apes (and, in fact, are just one peculiar kind of ape), yet we are obsessed with the features that distinguish us from our close relatives. The "big questions" in evolutionary anthropology, from why we stand upright to how our brains became so large, are all centered around distancing us from a prehistoric ape baseline. Despite our preoccupation…

Long-time readers of this blog know that "Laelaps" is not so much a stand-alone repository of my thoughts and opinions as an active writing lab; from the very beginning I have had bigger things in mind. One of those projects, my book Written in Stone, will be published later this year, and every now and then I have thrown together a few thoughts on what it is like to write a pop-sci book. I am hardly the only science blogger to have gone through this process, though, and starting next week I will be teaming up with two other geoscience writers in an effort to help potential book authors…

During the 1920's, poisons could be found in abundance in almost any New York apartment. Cyanide, arsenic, lead, carbon monoxide, radium, mercury, methyl alcohol and more; these materials were part of everyday life, especially bootlegged alcohol in the "dry" era when the only stiff drinks commonly available had to be distilled from more dangerous liquids. Accidental poisonings were not uncommon, but with the availability of so many lethal substances it was easy for some to use them for their own nefarious purposes. What might seem to be an accident might truly be murder, and, as Deborah Blum…
