John Durant is a leader of the growing ancestral health movement. Durant studied evolutionary psychology at Harvard prior to founding Paleo NYC and Barefoot Runners NYC, the largest Paleo and barefoot running groups in the world. In his new book The Paleo Manifesto: Ancient Wisdom for Lifelong Health, Durant argues for an evolutionary – and revolutionary – approach to health. Blending science and culture, anthropology and philosophy, Durant distills the lessons from his adventures and shows how apply them to day-to-day life. He blogs at HunterGatherer.com.

Due to an "administrative error," Health Canada sent letters to 40,000 medical marijuana users whose return address was "Medical Marijuana Access Program." In so doing, they outed tens of thousands of Canadians as medical marijuana users to their postal delivery people, people with whom they share their mailboxes, and others.

Last week, I linked you to a piece pointing out that three New York Times
op-ed pieces linking bacterial exposure (or lack thereof) to autism, celiac disease, and allergies were all written by the same guy
, Moises Velasquez-Manoff. His ideas are interesting, but there's also good reason to be skeptical. If you want to get a better idea of the arguments for and against Velasquez-Manoff's thesis, I'd recommend checking out this post at the Knight Science Journalism Tracker
, which links to several critical stories and to Velasquez-Manoff's response to them.
The ground in a Plaza de Pio XII, a square in Alicante, Spain has been decorated with a dazzle-paint-like pattern of high contrast wiggly white lines. It has caused seizures in some people with photosensitive epilepsy (20,000 people with epilepsy live in the region) and some elderly people have complained of dizziness while traversing the square. The square is centrally located, and some of its detractors argue that they have to cross it several times a day just to get around town. Here's some of the Google Translate text from the Diario Informacion piece by Alberola Pine:

In the past year, The New York Times
Sunday opinion page has run three different columns by Moises Velasquez-Manoff, a writer whose new book argues that the hygiene hypothesis — the idea that over-cleanliness can make you sick — is the one true cause behind everything from autism, to celiac disease, to allergies. While the hygiene hypothesis, itself, is perfectly plausible, Velasquez-Manoff's extension of it to cover a host of hot-button disorders and cures for said disorders is much less plausible ... something that was pointed out in a negative review of his book that ran in, yes, The New York Times

A nursing student named Janelle asked Adventure Time character designer Matt Forsythe to interpret the "Wong-Baker Facial Grimace Scale" -- used to help kids describe how much pain they feel -- using Finn. The result is just great.

Researchers at Finland's Tampere University have identified a set of viruses they believe to be responsible for Type 1 diabetes, and they have formulated a vaccine for it that has had promising results in mice. The enterovirus in question attacks the pancreas, and is similar to the virus that causes polio. They're forming a research syndicate to raise the €700m needed for human trials.

Lil sez, "Some doctors decided that it would help kids describe their poop accurately if they turned the verbal Bristol Stool Scale ('type 1 as 'rabbit droppings', type 2 as 'bunch of grapes', type 3 as 'corn on cob', type 4 as 'sausage', type 5 as 'chicken nuggets', type 6 as 'porridge', and type 7 as 'gravy'.') into 3D models, complete with clear resin 'toilet water'and a porcelain toilet to display them. Because how else would the kids differentiate floaters from sinkers?"

You do, however, have MRSA
. An adorable cartoon at the new blog BuzzHootRoar draws attention to something I'd never heard of before — a lot of the time, when your doctor thinks you've been bitten by a poisonous spider, you've actually been infected with antibiotic resistant bacteria. No spider involved. And the cartoon comes with citations, which is lovely.

As the US government stretches out into its second week, with federal food-safety and disease outbreak personnel sent home and prohibited from returning to work--even if they wanted to without pay!--a major foodborne-illness outbreak has begun. And it involves raw chicken meat.
The Food Safety and Inspection Service of the US Department of Agriculture has announced that hundreds of illnesses in 18 or more states were caused by chicken contaminated with Salmonella Heidelberg, traced to Big Poultry producer Foster Farms.

Congress's private gym -- whose budget is a closely held secret for "security" reasons -- has remained open during the shutdown. It was deemed an essential service. By John Boehner himself. (Possibly because so many Tea Party Congressmen live in their lavish tax-funded/tax-free offices and use the fancy club as their personal showers, rather than renting DC lodgings)
The staffers' gym was closed, however.

Walt Disney World is adding enough hours to its part time workers' rosters to allow them to qualify for Obamacare, helping their workers to get healthcare. They're hardly the only ones; a recent survey of CFOs at large firms shows that they've got a lot of company. But it's important to note because a) it's a good, honorable thing they're doing and b) it runs counter to the scare-stories that emphasize the tiny number of sleazy, greedy companies that are using Obamacare as justification to screw their workers by cutting hours and benefits.

Blizzident is a custom-made, 3D printed, whole-mouth-at-once toothbrush that claims to be able to clean your teeth in six seconds. It uses a mold of your teeth, lined with "a dense field of tailored bristles" that work with an integrated tongue-scraper and floss to conduct what appears to be a thorough scraping, brushing, and flossing of all the significant mouth-surfaces.

This 1863 image from the Wellcome Trust illustrates a distinctly vampiric set of "Syphilitic malformations of the permanent teeth" -- makes you wonder if the visual image of the vampire was inspired by the widespread horrors of untreated syphilis (for an exceptionally visceral window into a society wracked by untreated syphilis, have a look at the Mutter Museum's display of syphilitic skulls).

You're feeling tired and achy. Everything tastes strange, and something deep within warns you not to sample the chip dip in the staff room. You're just not up for much at all, really, and the malaise only grows as the day drags on. Sounds like a case for Dr. Wikipedia! Julie Beck, at The Atlantic, covers an initiative that could supplant the dismal Dr. Google and his psychotic colleague, Dr. Yahoo Answers -- but wonders whether we should be getting health information from the Internet at all.
Through Wikiproject Medicine, some medical professionals (and other health-savvy Wikipedia editors) have taken it upon themselves to improve the quality of medical information available on the site. And, in the same spirit, the University of California, San Francisco will be offering a class this year that gives fourth-year medical students course credit in exchange for editing Wikipedia articles. I spoke with Dr. Amin Azzam, a health sciences associate clinical professor at UCSF, who will be teaching the course, about how it will be run, and the impact that Wikipedia has on public health.
A 41-year-old Chinese man died from a rabies infection
that he picked up in an attempt to save his son from the disease. The boy was bitten by a rabid dog. The father sucked blood out of the wound in hopes it would remove any poison. The family ended up taking the boy in for shots, anyway, but the father turned them down, largely because of the cost.
In a piece on octopus farming, Katherine Harmon mentions a fascinating fact — octopuses don't have an adaptive immune system, the handy-dandy network of different immune-response cells that allow us vertebrates to more easily fight off infections our bodies have encountered before.
That's a problem if you're trying to raise a bunch of invertebrates in close quarters (as per a farm) because you can't immunize them against pathogens that could easily spread from one octopus to another. As a random biological tidbit, though, it's just damned fascinating. Check out this doctoral thesis for more information on how the octopus immune system does work. You should also read this story that looks at the evolution of the adaptive immune system and asks a key question — does having immune "memory" really make us that much better off than the animals that don't have it?

A few years ago, Harriet Hall googled "The One True Cause of all disease", just to see what the Internet would come up with. She counted 67 One True Causes before she got bored (52 of them made it into the handy chart above).
Besides making for an amusing anecdote, this little exercise also helps illustrate why there's a problem with ideologically driven medical treatments — the sort that comes from people who are pushing a lifestyle or a philosophy along with ostensible healthcare. It's both intriguing and convenient to think that, if we just open the right secret door, we can find the thing that's actually causing all our problems. The truth, unfortunately, seems to be that our bodies and the world they inhabit are complicated and messy and that lots of of things can lead to disease (doctors typically learn to divide these things into nine different categories, Hall says). In fact, a disease we think of as a single entity can have its roots in more than one thing. All of this is pretty obvious but it's the kind of obvious that's worth rubbing our noses in on occasion. If somebody tells you that everything from obesity to bipolar disorder to allergies to cancer all stem from the same root and can be treated or prevented with the exact same treatment, there's probably good reason to question what they're telling you.
Researchers from Boston Medical Center (BMC) and Boston University School of Medicine (BUSM) "studied 589 adults who screened positive for drug use at a primary care visit." They found "no differences between daily marijuana users and those using no marijuana in their use of the emergency room, in hospitalizations, medical diagnoses or their health status."

Today, Google announced the launch of Calico, a new company that will "focus on health and well-being, in particular the challenge of aging and associated diseases."
Former Genentech CEO Arthur D. Levinson, who is Chairman of the Board at both Genentech and Apple, is CEO and a founding investor of the new Google spinoff venture.
Noted Google+ user Larry Page posts this morning:
OK … so you’re probably thinking wow! That’s a lot different from what Google does today. And you’re right. But as we explained in our first letter to shareholders, there’s tremendous potential for technology more generally to improve people’s lives. So don’t be surprised if we invest in projects that seem strange or speculative compared with our existing Internet businesses. And please remember that new investments like this are very small by comparison to our core business. Art and I are excited about tackling aging and illness. These issues affect us all—from the decreased mobility and mental agility that comes with age, to life-threatening diseases that exact a terrible physical and emotional toll on individuals and families. And while this is clearly a longer-term bet, we believe we can make good progress within reasonable timescales with the right goals and the right people.
Hey, none of this health and wellness stuff should come as a surprise to internet old-timers who recall when the "web crawler"
was named "BackRub."
Time has an exclusive, in this week's cover story at the magazine. The short version: "the company behind YouTube and Google+ is gearing up to seriously attempt to extend human lifespan."

This article from Garry Tan reminded me of the tremendous work of Bruce K Alexander, a psychology professor who retired from teaching at Simon Fraser University in 2005. I read Alexander's first book, Peaceful Measures: Canada's Way Out of the 'War on Drugs' when it was published in 1990, and it had a profound effect on my outlook and critical thinking about drugs and the way that drug addiction is reported and discussed.
Alexander is well known for his Rat Park experiment, which hypothesized that heroin-addicted lab rats were being driven to drugs by the emisseration of life in a tiny cage, tethered to a heroin-dispensing injection machine. Other experimenters had caged rats with heroin-injecting apparatus and concluded that the rats' compulsive use of the drug proved that their brains had been rewired by addiction ("A rat addicted to heroin is not rebelling against society, is not a victim of socioeconomic circumstances, is not a product of a dysfunctional family, and is not a criminal. The rat's behavior is simply controlled by the action of heroin (actually morphine, to which heroin is converted in the body) on its brain.").
Alexander's Rat Park was a rat's paradise -- spacious, with plenty of intellectual stimulus and other rats to play with. He moved heroin-addicted rats into the park and found that the compulsive behavior abated to the point of disappearance -- in other words, whatever "rewiring" had taken place could be unwired by the improvement of their living conditions.
Alexander's work appears in Drugs Without the Hot Air, one of the best books on drug policy I've ever read, written by former UK drugs czar David Nutt. Both men are scientists who make the case that the our drug policy is more the product of political grandstanding than scientific evidence.

These are the ancient Egyptian hieroglyphs that are thought to refer to acne. They're part of a nifty piece by Hilda Bastian that looks at the history of our understanding about zits — where people thought they came from before we knew about their relationship to hormones and bacteria. And how some of the myths that originated in that pre-scientific understanding still affect our cultural attitudes about acne and the way anti-acne products are marketed to us today.
Here's a great piece by Anahad O'Connor that looks at the dozens of studies that are supposed to link the act of eating breakfast with weight loss
— and the problems that very quickly arise when you look at them closely. The biggest issue: Most of the advice you get telling you to eat breakfast if you want to lose weight is based on observational studies — large collections of information about people's lives and health that scientists then comb through looking for correlations. Like any correlation, those associations should be thought of as jumping-off points for more research, not proof of how you should live your life. With breakfast and weight loss, the truth seems to be that the two things may not be connected at all. For every study that shows them inextricably linked, another found no relationship at all ... or even an inverse
relationship, where skipping breakfast led to weight loss.
At Forbes, Katie Kelly Bell has an interesting look at the extremely subjective measurements happening behind the seemingly objective instruction to drink only "in moderation"

Yesterday, a story about human experimentation
spurred an interesting discussion in the comments about patient rights — can somebody who is dying make the informed decision to accept a treatment that could lead to them dying sooner? At Scientific American today, an HIV doctor has written a moving account of dealing with a very similar question, as one of his patients made the choice to refuse food
, and her family and doctors were faced with the task of deciding whether or not to feed her through a stomach tube.
University of Guelph researcher Emma Allen-Vercoe and her team have devised a method for creating artificial poop for use in fecal transplants, a promising therapy for people whose intestinal flora have been damaged by illness, antibiotics, or other therapies. The recipe involves a combination of indigestible cellulose and a starter culture of fecal bacteria. These are mixed in an airtight chamber and passed through a "robogut" -- a mechanical analog of the human digestive system that produces the finished turd.
