Blog of the Week:
Do you believe in dog? is a brand new blog. It is written by two dog researchers, one in New York City, the other in Yarra Valley just outside of Melbourne, Australia. Julie Hecht you may already know from her wonderful blog Dog Spies, her writing in The Bark, or her research which we covered here at SciAm. She studies (and teaches about) dog cognition. Mia Cobb, the Australian, did her research in animal behavior on birds and ants, but now works on issues of dog shelters, welfare and performance science of working dogs. What is the coolest thing about the blog is that the two of them write for each other, addressing each other in each post, thus teaching and learning from each other in a dialogue to which we are all invited to participate in and contribute.

Tales from the OR by Summer Ash:
WARNING: This post contains my blood and guts, literally. If you re squeamish, I recommend skipping this one. What follows is my journey through the operating room at Columbia-Presbyterian on July 18, 2012. Apologies, but I couldn t help starting off with yet another pop culture reference (this time from Wes Anderson s Rushmore)?.
An example of why it is important to distinguish evolution as fact, theory, and path. by T. Ryan Gregory:
I, and others, have pointed out that there are three aspects of evolution: evolution as fact, evolution as theory, and evolution as path. Evolution as fact refers to the historical reality that species are related through common ancestry. This is supported by a massive amount of evidence from a wide array of independent sources. Evolution as theory refers to the proposed explanations for how descent with modification occurs mutation, natural selection, genetic drift, etc. Evolution as path refers to the actual patterns that have occurred during the history of life, such as when certain events (e.g., branching points, extinctions, etc.) took place, how lineages are related, when and how many times certain traits evolved, and such. The important point is that these three components are largely independent?
The Childhood Aquatic by John Romano:
There is a structurally integral part of my psyche that is the keystone to my existence. I am not sure how it was placed in such a vital position, but it seems this part of me is embedded in my DNA. Something that I can never remember being without. The absolute and total fascination with the natural world?.
Abraham Lincoln and The Embalmer by Romeo Vitelli:
The assassination of Abraham Lincoln on April 15, 1865 shocked a nation still recovering from four years of bloody civil war. Along with the hunt for his killers and the uncovering of the assassination plot against the President and several other members of his administration, there was also the logistic nightmare of his funeral and the need to transport the President?s body by train from Washington D.C. to his final resting place in Springfield, Illinois. Since the funeral train would retrace the route that Lincoln had traveled to Washington following his election, the body would be viewed by millions of mourners along the way during the numerous planned stops. All of which raised the question of how to keep the body preserved long enough to reach its destination. Considering the fact that funeral embalming was a relatively new development at that time, some very special arrangements needed to be made?
Inspiration from bassist Victor Wooten shows me a new way to deal with my child-as-scientist frustrations by Marie-Claire Shanahan:
I have a confession to make: I cringe a little every time I see a school science or science outreach program justified by saying something like, Young children are natural scientists, truly curious about the world (That particular quote is from the Delaware Museum of Natural History). I feel like a curmudgeon about it because it often comes with really good intentions to get students actively involved in doing science (something I definitely support)?.
How a Tick Bite Made Me Allergic to Meat by Helen Chappell:
The last time I ate a hamburger, I spent the night in the emergency room. There wasn t anything wrong with the hamburger itself aside from being a bit overdone but it sent me into anaphylactic shock. It wasn t always this way?
Are wolves really all that? by DeLene Beeland:
Have conservation scientists become carried away, touting the ecological benefits of wolves where there are perhaps dare I say it? not as many as we believe there to be? Perhaps some people in the media, and even some in science, have gotten carried away with the ecological changes that wolves are actually capable of mediating, says globally-renowned wolf biologist L. David Mech in his most recent paper Is science in danger of sanctifying the wolf? ?
Losing One s Head: A Frustrating Search for the Truth about Decapitation by Lindsey Fitzharris:
If you ever find yourself in a pub with me, chances are that at some point, the conversation will turn to death. Not just death, but the terrifying and horrible ways people have succumbed to it in the past. I have often heard a story retold about a man who attended the execution of his friend during the French Revolution. Seconds after the guillotine fell, the man retrieved the severed head and asked it a series of questions in order to determine whether or not it was possible to retain consciousness after decapitation. Through a system of blinking, the victim allegedly communicated his message back to his friend. The ending to this story changes according to the whims of the narrator or perhaps the number of drinks he or she has consumed by that time. I wondered: was this the 18th-century equivalent to an urban legend? Or could there, in fact, be a degree of truth in this ghastly tale??.
A Dirty, Deadly Bite by Brian Switek:
Dragons aren t real. At least, the fire-breathing wyverns and coiling wyrms of medieval lore aren t. Those reptilian menaces were products of superstition and pre-scientific ideas about prehistoric creatures. They were ugly amalgamations inspired by our fears and actual fossil remains of long-extinct mammals and dinosaurs. But in the early 20th century, reporters excitedly relayed the discovery of what quickly became known as the Komodo dragon ten foot long lizards that had coexisted with humans on South Pacific islands for thousands of years, but had only just been recognized by western science?.
The Itsy Bitsy Drummer by Helen Shen:
Rrrr RRR Thack! Thack! Thrusting his front legs skyward, the male jumping spider shakes his rear end to send thumps, scrapes, and buzzes through the ground. He s playing for a female s attention, dazzling her eight eyes with semaphore while drumming out seductive seismic signals. A few missteps could turn the spider s performance into a dinner show with the star as the main dish. The ferocious female demands precise choreography, set to a groovy beat that UC Berkeley behavioral ecologist Damian Elias is working to decipher?.
