In the early 1970’s, Io, the innermost large moon of Jupiter, was somewhat of an enigma. Unlike Europa and Ganymede, it did not exhibit water ice adsorption bands it its IR spectra. Its density suggested that it was a rock and metal planet, but the surface reflectance was unlike anything known to science. This problem was addressed brilliantly in a Science paper by Fanale, Johnson, and Matson,... Read more »
Many scientists think that free-will is an illusion. That is, intentions, choices, and decisions are made by subconscious mind, which only lets the conscious mind know what was willed after the fact. This argument was promoted long ago by scholars like Darwin, Huxley, and Einstein. Many modern scientists also hold that position and have even [...]... Read more »

The diversity of life is a puzzle for ecologists and evolutionary biologists. The principle of competitive exclusion suggests that if two species are competing for the same resource, one of them should eventually win and the other should become extinct. So if you have n different food sources, you should end up with (at most) [...]... Read more »

When I was in college I would sometimes have late night conversations with the guys in my dorm, and the discussion would random-walk in very strange directions. During one of these quasi-salons a friend whose parents were from Korea expressed some surprise and disgust at the idea of wet earwax. It turns out he had [...]... Read more »

Supply Chain Risk Management is one way to look at risks within a company (and beyond). But there are broader and more narrow disciplines as well, with Business Continuity on the one end and Supply Chain Crisis Management on the other.
I wanted to get an overview of current research on Supply Chain Crisis Management first, so today I explore "Managing supply chains in times of crisis: a review of literature and insights" by Natarajarathinam, Capar and Narayanan. The article is focussed on ........ Read more »

Similar to JAMA, which publishes an annual publication focusing on Medical Education, the Academic Emergency Medicine (AEM) journal just published a AEM-CORD supplement focusing on EM education. I was fortunate to be involved with one of the papers published in this supplement.This paper, written on behalf of the Clerkship Directors in EM (CDEM) and the Association of Academic Chairs of EM (AACEM), reviews the past, present, and future of EM in the U.S. medical school curriculum.EM faculty membe........

As you stretch for yet another delicious cup cake, the abstemious little voice in your head pleads 'Don't do it!'. Does this self talk really have any effect on your impulse control or is it merely providing a private commentary on your mental life? A new study using a laboratory test of self-control suggests that the inner voice really does help.
Alexa Tullett and Michael Inzlicht had 37 undergrads perform the Go/No Go task. Briefly, this involved one on-screen symbol indicating that a button ........ Read more »

Brains are what mathematicians call "information sources". At least this is one of the results of a set of elaborate experiments together with sophisticated analyses and computations reported in the current issue of Nature Neuroscience (subscription required). The article, entitled "Intrinsic biophysical diversity decorrelates neuronal firing while increasing information content", studies a set of neurons in the brain's main olfactory center, the olfactory bulb. These ne........ Read more »

Are average composite faces the most attractive faces or are highly attractive faces markedly different from average faces? Rhee & Lee (2010) agrees with Perrett & Yoshikawa (1994) that the most attractive face is actually the average of attractive faces and that an average face; while attractive, is not the most attractive.They also argue that previous concepts of beauty such as the divine proportion (golden ratio) are not a good measure of beauty across different races and should not b........

Medical researchers believe that the best way to protect eye from glaucoma is to protect the optic nerve from a sudden increase in intraocular pressure since ocular hypertension is the most important risk factor for glaucoma. Accordingly, for the past few years, huge research efforts have been made to develop a powerful biotechnical approach to protect the optic nerve. As a result, scientists discovered that Heat Shock Proteins (HSPs) can be a new powerful modality for the protection of optic ne........ Read more »

A lot his been written on this blog about medical professionalism and online social networks such as Facebook. There’s a lack of policies on Internet use for many med schools. In short, on social networking sites patients may learn information about their doctors or medical students that compromises the professional relationship. Threats to patient confidentiality [...]

Social psychology is a fascinating area of psychological research.One of the many famous pieces of research to come out in the history of social psychology is the Bobo Doll Experiment, conducted by Albert Bandura. Essentially, Philips (2007) states that Bandura showed children images of either an actor attacking a clown, or not. After watching the film, the children were then allowed to play in a room full of toys. Philips (2007) states that those children who had watched the film would go on to........ Read more »

Previosly, I calculated a bunch of ad-hoc power curves from GISTEMP data. Power is essentially a reframing of the p-value, to see the significance of the trend lines in the global temps. However, power calculations are inherently very noisy, hence, my ad-hoc way of aggregating the data. Another method is to bootstrap through the responses [...]... Read more »
You guys, there is SO much science out there. SO MUCH. Grrl and I agree, so much to blog, so little time. Anyway, I found this great paper in the latest Table of Contents for Nature, and went “ooooh, must blog!” And then SciAm beat me to it. No fair, I bet they had it [...]... Read more »

I’ve previously discussed water control technologies at Chaco, where they were particularly important given the extreme aridity of that area even by Southwestern standards. There is abundant evidence, however, that water control was a widespread activity throughout the ancient Southwest, even in areas with more reliable water sources. The best-studied water control systems have been [...]... Read more »

One of the authors of this article is the Walter Graham, Executive Director of UNOS, the agency that manages OPTN. He is neither a physician, mental health professional, living donor nor transplant recipient. He is but a simple bureacrat. From the cited article, comes this little gem: OPTN members also have the responsibility of helping protect potential recipients from hazards that can arise from public appeals.This hit me on a good day, meaning that I laughed hysterically rather than plot the ........

Do you ever get the feeling that one reason a lot of people can't stomach the theory of natural selection is that they hate the idea that everything we see around us is the result of blind chance. Hostility to the notion of chance is certainly a recurrent theme in creationist objections.
Of course, evolution by natural selection is not really evolution by chance, as the creationists claim. But even so chance does play a role. Stephen Gould, in many of his essays, repeatedly drove home the impor........ Read more »

This week, the NFL has modified the rules of tackling. Now, players can only tackle within the torso region and the intensity of hits will be monitored. This has all occurred because of the numerous concussions players have suffered this year alone and from continuing emerging science showing the long-term neurobehavioral consequences of playing football. Brain damage, psychiatric disorders, drug abuse, even suicide. ... Read more »
Whole-genome sequencing is a game-changer for human genetics. It is now possible to deduce every base of an individual’s genome (all 6 billion of them – two copies of 3 billion each) for a couple of thousand euros, and dropping. (Yes, euros). Even Ozzy Osbourne just got his genome sequenced! For researchers searching for the causes of genetic disease (or resistance to vast quantities of drugs and alcohol), this means they no longer have to infer where a mutation is by tracking a sampling........

When I was a kid, a popular ghost story that we would all tell around this time of year was the story of "Bloody Mary". The story is actually very widespread here in the U.S., to the point that it has a Wikipedia page, a post on the mythbusting/fact-checking site Snopes.com, a plethora of YouTube videos devoted to the subject, and numerous mentions in movies and television shows. If, somehow, you have never heard this story, it goes like this:In Colonial times, there was a beau........ Read more »
