The hygiene hypothesis of allergies “argues that exposure to more natural environments such as farms early in life helps train the body to respond appropriately to harmless microbes and pollen”. Could also be called the “let your kids eat dirt hypothesis”. Somewhat related story: my dad had allergies when he was a kid but then got stung by a bunch of bees one day and boom, no more allergies.
President of the Oglala Sioux Tribe on the Pine Ridge Reservation, Cecilia Fire Thunder, says:
I will personally establish a Planned Parenthood clinic on my own land which is within the boundaries of the Pine Ridge Reservation where the State of South Dakota has absolutely no jurisdiction.

Michael Crichton on the sad state of patents in the US, particularly those related to medicine. “Any doctor who reads a patient’s test results and even thinks of vitamin deficiency infringes the [homocysteine/B-12] patent. A federal circuit court held that mere thinking violates the patent.”

So, it’s day five of my cold[1]. Last night, I was down to only two out of my five senses. My sense of taste and smell left the scene sometime on Saturday. On Sunday, I had salad and fruit for lunch because I figured if I can’t taste anything, I might as well eat healthy. Trying to smell or taste strongly aromatic substances like wine or scented shower gel produces a sensation not unlike that of tasting or smelling something, except there’s no smell or taste. It’s the weirdest thing…I don’t even know how to properly describe it. It’s like there’s a ghost of a taste and when I think too hard about trying to really taste it, it’s gone. It’ll be a relief when I finally decongest and can enjoy food again[2].
And then yesterday while driving, we went from sea level up to around 600 ft of elevation, which caused the pressure to build up in my head enough to affect my hearing. By 4pm, everything was kind muffled and I was asking Meg speak up repeatedly. I could just barely hear the hum of the highway under the car. Last night at dinner, I couldn’t taste anything, smell anything, hear anything, and my voice was so gravelly from my cold (and probably way too loud from overcompensating for the hearing loss) that listening to me was probably not very pleasant. My ears finally popped somewhat this morning and I can hear ok again, but smell and taste are still missing. Come back, guys, I miss you!
Update: Here’s an article by Jason Feifer from the Washington Post about his investigation into his poor senses of taste and smell. (thx, mim)
[1] After a bit of research this AM, I’ve determined that what I have is a cold and not the flu.
[2] I remember reading a book or article once that mentioned a person who lost their sense of taste and when it would briefly return, that person would drop whatever they were doing and go eat a great meal. Anyone know where that story is from?
Scientists have found a probable carrier for the ebola virus: fruit bats. According to the WHO, ebola causes death in “50-90% of all clinically ill cases”.
Why is the incidence of cancer in India so much lower than in the US?
In the five years since the sequencing of the human genome, “much of the data have little immediately useful meaning, and the research has produced only a trickle of medicine”. And where medical science has failed, hucksters have filled the gap.
Gelf Magazine says “a new study uses shoddy stats to hold the movie industry responsible for society’s poor health choice”. “But even if we disregard the fact that people don’t necessarily take their public-health cues from films like Scary Movie and Rambo: First Blood Part II, the study has serious flaws that undermine even its tenuous claim on our attention”.
Among laparoscopic surgeons, those who have played video games in the past are significantly faster and less error-prone in a surgical training exercise than those who have never gamed. Even better were those who are current gamers…they realized 30% gains in speed and accuracy over their non-gaming counterparts.
Laurie sends along an account of the week she spent in a psych ward. She says she’s “trying to publicize it in order to remove some of the stigma of mental illness”. Reminds me of Heather’s accounts of her psych ward stay last year.
Making sense of the appendix, the one in your body, not the one in books. “Perhaps the appendix lifted the odds that our ancestors could resist childhood diseases and live to childbearing years.”
The science of Lance Armstrong. Between 1992 and 1999, he increased his muscle efficiency by 8 percent, a gain previously thought to be impossible.
I was somewhat disappointed in the 2003 edition of this collection, especially after enjoying so much the last three editions. Perhaps Oliver Sacks and I disagree on what makes science writing good. The two best articles were 1491 by Charles Mann about what the Americas were like before Columbus landed and the effect of the European arrival:
In North America, Indian torches had their biggest impact on the Midwestern prairie, much or most of which was created and maintained by fire. Millennia of exuberant burning shaped the plains into vast buffalo farms. When Indian societies disintegrated, forest invaded savannah in Wisconsin, Illinois, Kansas, Nebraska, and the Texas Hill Country. Is it possible that the Indians changed the Americas more than the invading Europeans did? “The answer is probably yes for most regions for the next 250 years or so” after Columbus, William Denevan wrote, “and for some regions right up to the present time.”
and Atul Gawande’s The Learning Curve, an article on how doctors need to learn on the job (while potentially making costly mistakes) in order to become more effective overall:
In medicine, there has long been a conflict betwenn the imperative to give patients the best possible care and the need to provide novices with expericne. Residencies attempt to mitigate potential harm through supervision and graduated responsibility. And there is reason to think that patients actually benefit from teaching. But there is no avoiding those first few unsteady times a young physician tries to put in a central line, removes a breast cancer, or sew together two segments of colon. No matter how many protections are in place, on average these cases go less well with the novice than with someone experienced.
