Blog of the Week:
Over the years, Better Posters blog has become the “Go To” place to send students when they start preparing posters for their first scientific meetings. Updated weekly, on Thursdays, this blog by Dr. Zen Faulkes (who also blogs at his other two awesome blogs NeuroDojo and Marmorkrebs, as well as on the #SciFund blog) provides ideas, suggestions, underlying theory, and thorough, fair critiques of poster design for scientific conferences. It is a link I (and I am sure many others) send whenever asked what is the best resource for preparing a good poster. Zen Faulkes also has a broader category of posts about presentations in general, both oral and poster, under the Zen of Presentations tag on his other blog.
Phineas Gage’s connectome by Mo Costandi:
Anyone who has studied psychology or neuroscience will be familiar with the incredible case of Phineas Gage, the railroad worker who had a metre-long iron rod propelled straight through his head at high speed in an explosion. Gage famously survived this horrific accident, but underwent dramatic personality changes afterwards. In recent years researchers reconstructed his skull and the passage of the rod through it, to try to understand how these changes were related to his brain damage. Now, neuroscientists from the University of California, Los Angeles have produced Gage’s connectome – a detailed wiring diagram of his brain, showing how its long-range connections were altered by the injury.
Replication studies: Bad copy by Ed Yong:
Positive results in psychology can behave like rumours: easy to release but hard to dispel. They dominate most journals, which strive to present new, exciting research. Meanwhile, attempts to replicate those studies, especially when the findings are negative, go unpublished, languishing in personal file drawers or circulating in conversations around the water cooler. “There are some experiments that everyone knows don’t replicate, but this knowledge doesn’t get into the literature,” says Wagenmakers. The publication barrier can be chilling, he adds. “I’ve seen students spending their entire PhD period trying to replicate a phenomenon, failing, and quitting academia because they had nothing to show for their time.” These problems occur throughout the sciences, but psychology has a number of deeply entrenched cultural norms that exacerbate them. It has become common practice, for example, to tweak experimental designs in ways that practically guarantee positive results. And once positive results are published, few researchers replicate the experiment exactly, instead carrying out ‘conceptual replications’ that test similar hypotheses using different methods. This practice, say critics, builds a house of cards on potentially shaky foundations…
Plan X; or, Planning White’s Small Step by Amy Shira Teitel:
In 1964, the launch schedule for the Gemini program was set and it was tight. Missions with new objectives would launch every eight to ten weeks taking NASA a step closer to the Moon each time. But hardware setbacks and some surprising feats by Soviet cosmonauts took a toll on the schedule. In the first half of 1965, NASA developed a plan that would see Gemini match and begin to overtake the Soviet Union in space. It was done largely in secret and known internally as Plan X….
Against the Infantilization of the Natural History Museum by Justin Erik Halldór Smith (and related: Relics With Much to Tell About Bird Diets May Be Lost to Time by Sarah Fecht):
…The project of exhaustively collecting and describing the basic kinds of large animal, and analyzing and displaying these animals’ bodily parts and systems, is a project that gained momentum in the late Renaissance and that was largely completed by the end of the 19th century. Like, say, realist painting in the Western tradition, it is a project that has a bounded history (indeed the two histories fairly closely overlap one another). This means that an alpaca intestine displayed in formaldehyde is a sample of a part of a South American camelid; but it is also an artefact of a modern European knowledge project. In this respect a proper natural history museum, that is to say an unreconstructed adult natural history museum, is really two museums at once: it is a museum of nature, but also a museum of the history of a very singular attempt to know nature quite literally inside-out….
….To devise a good layout requires some understanding of what museum visitors do, and there’s surprisingly little literature on this topic. Most of the studies of museum-goers that I’ve seen rely on questionnaires. They ask people what they did, what they learned, and what they liked and didn’t like. No doubt there are virtues to this technique, but it assumes that people are aware of what they’re doing. It doesn’t take into account how much looking depends on parts of the brain that are largely instinctive and intuitive and often not easily accessible to our rational consciousness. Was there another mode of investigation and description that would illuminate what was actually taking place?…
Lies You’ve Been Told About the Pacific Garbage Patch by Annalee Newitz:
You’ve probably heard of the “Pacific garbage patch,” also called the “trash vortex.” It’s a region of the North Pacific ocean where the northern jet stream and the southern trade winds, moving opposite directions, create a vast, gently circling region of water called the North Pacific Gyre — and at its center, there are tons of plastic garbage. You may even have seen this picture of the garbage patch, above — right? Wrong….
The (misunderstood) language of DNA by Genegeek:
I love analogies and use them often to get people to think about scientific concepts in new ways. I’ll share some of my favourite ones on the blog but today, I want to talk about Analogies Gone Bad….There is a lovely analogy to help people understand DNA code: DNA can be seen as a language…
Killers that sux by DrRubidium:
You might notice the sting of the injection. Within seconds you’d realize you’re having trouble moving your eyes and fingers, followed by your arms and legs. If you were standing, you’d collapse. In a heap on the floor, you’d realize nearly every muscle in your body was paralyzed. Being fully conscious, your sense of panic would be rising as rapidly as the paralysis was spreading. Swallowing and breathing has become more and more difficult. Slipping into unconsciousness, your last conscious thought may well be “I am going to die.”…
The American Psychiatric Association have just published the latest update of the draft DSM-5 psychiatric diagnosis manual, which is due to be completed in 2013. The changes have provoked much comment, criticism, and heated debate, and many have used the opportunity to attack psychiatric diagnosis and the perceived failure to find “biological tests” to replace descriptions of mental phenomena. But to understand the strengths and weaknesses of psychiatric diagnosis, it’s important to know where the challenges lie….
Do Plants Smell Other Plants? This One Does, Then Strangles What It Smells by Robert Krulwich:
“Plants smell,” says botanist David Chamovitz. Yes, they give off odors, but that’s not what Chamovitz means. He means plants can smell other plants. “Plants know when their fruit is ripe, when their [plant] neighbor has been cut by a gardener’s shears, or when their neighbor is being eaten by a ravenous bug; they smell it,” he writes in his new book, What a Plant Knows. They don’t have noses or a nervous system, but they still have an olfactory sense, and they can differentiate. He says there’s a vine that can smell the difference between a tomato and a stalk of wheat. It will choose one over the other, based on…smell! In a moment I’ll show you how….

Why Aren’t Cities Littered With Dead Pigeons? by John Metcalfe:
Any fair-sized city in the United States is lousy with pigeons, hoovering up bread crumbs from public squares and head-bobbing so much they look like little Jay Zs groovin’ to some fresh beats. The favorite rumpus room of the pigeon, New York City, is thought to contain anywhere between 1 and 7 million of the flapping rats of the sky. So where are all the dead ones?
