sa smith | May 1, 2008This is a repost from the old ERV. A retrotransposed ERV :P I dont trust them staying up at Blogger, and the SEED overlords are letting me have 4 reposts a week, so Im gonna take advantage of that!
I am going to try to add more comments to these posts for the old readers-- Think of these as 'directors cut' posts ;)
Last summer, when Behe released his tome-of-TARD 'Edge of Evolution', I had absolutely no intention of reading it. If Dude had anything to say, he would publish it. But I kept hearing from friends that he was saying some crazy stuff about HIV.
He was.
I corrected him.
There is…
sb admin | April 29, 2008This is a reprint from my old blog that will provide necessary backgroud for an upcoming story. Thanks for your indulgence.
I am often asked my opinion of chiropractic care. My usual answer (based on evidence) is that it can be somewhat helpful in the treatment of low back pain. That's it. Any further claims are complete and utter bullshit. Many chiropractors practice ethically, and recognize the correct scope of their abilities...many do not.

Chiropractic is the theory and practice of correction of "vertebral subluxation processes" to treat and cure disease. It…
clock | April 29, 2008Why We Sleep: The Temporal Organization of Recovery:
"If sleep does not serve an absolutely vital function, then it is the biggest mistake the evolutionary process has ever made," Allan Rechtschaffen said. Studies of sleep and sleep deprivation suggest that the functions of sleep include recovery at the cellular, network, and endocrine system levels, energy conservation and ecological adaptations, and a role in learning and synaptic plasticity.

oracknows | April 28, 2008Over the weekend there was a very good article in the Concord Monitor about Kathleen Seidel and her legal battle with Clifford Shoemaker, whose intrusive "fishing expedition" subpoena recently drew condemnation even from prominent antivaccination activists such as David Kirby and Dan Olmsted and was ultimately quashed with the possibility of sanctions. What this article does a good job for those new to the debate is to put things in some perspective in a relatively brief treatment; I encourage you to read the whole thing, and I will focus mostly on a couple of interesting tidbits in the…

Welcome to the sixth edition of the Cabinet of Curiosities carnival. Whether your taste runs to Wunderkammern or Curiosities, blogs are treasure rooms for modern collectors of the strange and marvelous. Let's start with this perfect miniature cabinet of crochet motifs by JPolka at the oh-so-aptly named…
clock | April 25, 2008I was kicking myself all day yesterday because I forgot to take my camera with me for most of the day. First, my mother and I went to the bank to do some business which, of course, made us hungry so we stopped by a bakery and got fresh djevrek (no, although it looks like a sesame bagel, it is not - it is much lighter and crispier). Mmmmmm....
Then we went to the main building of the Natural History Museum and made some contacts there. The Director was at a meeting, but the secretary is smart, hip and on-the-ball and will be a great contact for the future as they try to design a new website…

There's a new woo in town. Unfortunately, it's the same as the old woo.
I first noticed it around Christmas. Inexplicably, I started getting a greatly increased amount of traffic to an old Your Friday Dose of Woo post of mine. The post to which I'm referring is one that I did a year and a half ago about some fabulously silly woo that claimed to remove toxins through the soles of your feet through a special foot pad, which inspired me to entitle the post These boots were made for detoxifyin'. This product in question was called "Miracle Patches" and, it was claimed, can remove all manner of…
cortex | April 23, 2008Over at the wonderful World's Fair, Ben Cohen has an interview with Kelly Joyce, author of the forthcoming Magnetic Appeal: MRI and the Myth of Transparency. Here is how Joyce summarizes the main argument of her book:
In the United States, MRI is socially constructed as a sacred technology--one that represents progress, certainty, and good health care. The technique's sacred status is achieved in part because cultural ideas link anatomical pictures and mechanical reproduction to transparency and truth. But, it is also achieved because information about contexts and actors is often missing…
sb admin | April 22, 2008The post hoc ergo propter hoc fallacy is one of the great weapons in the arsenal of denialists. The reason it works so well is it makes sense. As my readers know, my daughter is dealing with a nasty respiratory virus. One of the doctors told my wife, who is not a medical professional, that kids with this virus go on to develop asthma. My wife was not pleased to hear this. What the doc didn't tell my wife was whether or not there is a causal relationship between the infection and asthma. It is also true that kids who get RSV end up going to school.
Asthma is a common illness. RSV is more…
oracknows | April 22, 2008Yesterday I came across a blog exchange between Dr. Jekyll & Mrs. Hydeand fellow SBer Physioprof about principal investigators (PIs) who still do experiments in the lab. For those not in the science business, a "principal investigator" is in general the faculty member who runs the lab and whose grants fund the salaries of the postdocs, graduate students, and technicians working in the lab. J&H pointed out (correctly) that few PIs who have been faculty more than five years do any actual lab work anymore and described the case of a PI who persists in doing experiments himself,…
sb admin | April 21, 2008One of the hot topics around here lately is authority and anonymity. It's a terribly difficult philosophical question----how can you ever trust a source of information that is second hand? And yet ultimately we all are forced to do it most of the time.
A potent weapon in the denialist arsenal is the fake expert. The profusion of these charlatans makes identifying trustworthy sources even more important. We have many ways of doing this. We often use our intuition, a powerful but notoriously dicey skill. Sometimes we go by word-of-mouth. Sometimes, we go to established sources of…
razib | April 20, 2008If you don't like the word "racial," just substitute "population." In any case, Many African-Americans Have A Gene That Prolongs Life After Heart Failure:
About 40 percent of African-Americans have a genetic variant that can protect them after heart failure and prolong their lives, according to research conducted at Washington University School of Medicine in St. Louis and collaborating institutions.
...
"By mimicking the effect of beta blockers, the genetic variant makes it appear as if beta blockers aren't effective in these patients," he explains. "But although beta blockers have no…
revere | April 18, 2008If you want to know how far we've come since the early days of discussing community preparations for a possible influenza pandemic, take a look at a story at CIDRAP News about a new guidance document prepared by the Association of State and Territorial Health Officials (ASTHO) and its partners. This is described as the first federal document of its kind prepared outside the federal government (although with a grant from CDC). It's about how to provide necessary resources and services to those who will need it most but who are also the hardest to reach. The 105 page document is aimed at state…
terrasig | April 17, 2008Dr Kimball Atwood IV at Science-Based Medicine and my long-time blogging colleague Orac have spilled oceans of e-ink on the institutionalization of alternative or integrative medicine in North America's top academic medical centers. Complementary and alternative medicine (CAM) is now often called "integrative medicine" to intellectually justify the incorporation of evidence-free, anecdotal practices into the business of academic medicine. Of course, integrative medicine does co-opt a few areas of conventional medicine, like nutritional and psychological counseling, supported by an evidence…

On this day in 1943, Albert Hofmann (right), a chemist working for the Swiss pharmaceutical company Sandoz, discovered the psychedelic properties of LSD. Hofmann had actually first synthesized the drug 5 years earlier, as part of a research program in which the therapeutic effects of derivatives of ergot alkaloids - chemicals produced by a fungus - were being investigated.
In his autobiography, LSD: My Problem Child, Hofmann explains how he accidentally ingested the drug while synthesizing it in the laboratory:
It seemed to have resulted from some external toxic influence; I surmised a…

By Ousmane Diallo
Last week in class we tackled an interesting topic, the role of Mycobacterium Avium Paratuberculosis (MAP) in the genesis of Crohn's disease (CD) and ulcerative colitis (UC). The authors Saleh E. Naser (oops the name means in Arabic 'The virtuous helper') and colleagues detected using Polymerase Chain Reaction (PCR) techniques in a lab based case controls study "viable MAP in peripheral blood in higher proportion of individuals with Crohn than controls". Not surprising after all since the pathology of…
sb admin | April 13, 2008Think about your own experiences---you're at a party or a restaurant, and someone you're with says something obviously racist. You cringe, but given the setting, you can't decide how to react; after a pause, you probably decide to say something. Now imagine you're at meeting for work, and a senior partner says something racist. You want to say something, and you even know that under some circumstances there are laws behind you, but you don't want to get branded a trouble maker and risk subtle (or not-so-subtle) discrimination.
Now imagine you are sitting in the doctors' lounge, and a…

A concise but fascinating medical detective story appears in the letters of this week's (10 Apr 2008) issue of the New England Journal of Medicine (free full text at the time of this posting.).
An astute group of physicians at Leipzig Hospital in Germany noted a local surge of young people presenting with classic symptoms of…
oracknows | April 11, 2008It's that time of year again. Actually, it's well over a month past that time of year.
Long-timers may remember that, near the very beginning of my old Blogger blog over three years ago, I did a post entitled What is an altie? It was basically a Jeff Foxworthy-like listing of "You just might be an altie if..." statements that, I think, had a good point. For those of you not familiar with the term "altie," it was coined on the Usenet newsgroup misc.health.alternative to describe a certain hardcore variety of alternative medicine aficianado who is utterly immune to evidence or reason. The…
sb admin | April 10, 2008In order to bring you your daily dose of science, the Great Seed Overlords must pay the bills. Like any other medium, one of the ways this is done is by selling ad space. Internet ad engines generally have some sort of algorithm that choses ads based on the page content, thereby targeting readers' interests. If you doubt the sophistication of these methods, check your amazon.com suggestions, or your google search page.
For a skeptical blogger, this can make for some interesting ads. One of mine is for a book called Water: For Health, For Healing, For Life, by F. Batmanghelidj, M.D. I've…
