In related news, this video taught me that the parasite giardia is sometimes called "beaver fever". Why? Because one of its major reservoirs — species that can comfortably host a parasite and pass it on to others — is, yes, the beaver.
Now here's the part you probably don't want to hear. Giardia is transmitted via what's known as the "fecal-oral route".
Now, nobody intentionally goes out and eats beaver shit. (One hopes. But this is the internet.) But beavers do shit in the woods. Near woodland streams. Which means that unwary hikers and backpackers can end up ingesting giardia when they drink from what appears to be crystal-clear waters.
The crab-louse is in apparent decline, a situation that some doctors and entomologists attribute to widespread Brazilian waxing. Though, as Skepchick points out, there's a huge industry that stands to make a lot of money from this claim, and not a lot of evidence to back it up:
“Pubic grooming has led to a severe depletion of crab louse populations,” said Ian F. Burgess, a medical entomologist with Insect Research & Development Ltd. in Cambridge, England. “Add to that other aspects of body hair depilation, and you can see an environmental disaster in the making for this species.”
...“We put the flag out, so to speak, if we see a case of pubic lice nowadays,” [Janet Wilson, a consultant in sexual health and HIV] said in an e-mailed response to questions. “The ‘habitat destruction’ of the pubic lice is increasing and they are becoming an endangered species.”

By popular demand (and the help of intrepid readers Broan and theophrastvs), I present you a video clip of the humanoid robot known as Vomiting Larry.
Larry is used to study the way particles of puke become aerosolized, and how those particles spread and help infect other people. That's important, because it explains one of the ways that viruses spread by vomiting manage to end up in everyday things like, say, frozen raspberries. Aerosolized vomit isn't something you can spot. It doesn't clean up easily. And even just a drop of it can pass on plenty of viruses.
Carl Zimmer had a great piece up yesterday on norovirus, the virus that researchers are studying with the help of Vomiting Larry. His story has more info on how that virus spreads and will give you a better idea of why Vomiting Larry is so important.
Researchers at MIT used network theory to put together a model of how an infectious disease might spread around the world with the help of American airports. The model shows which features—geography, connectivity, levels of use—most impact the spread of disease and use that to predict which airports would be at the heart of an outbreak.
Some are not a shock. ("Oh, you say JFK and LAX could serve as worldwide hubs for disease?") But the model also reveals some surprising spark points. Like, say, Anchorage. It's also interesting to see the order that the model ranks airports in. Would you believe that Honolulu has more disease-spreading power than Atlanta?

At Discover's big-idea blog The Crux, Emily Willingham has a really interesting post about the prevalence of autism—is it actually increasing, or is this really about medical definitions and increased attention?
This is a topic we've talked about here on BoingBoing before, most recently back in March, when Steve Silberman offered some scientific evidence that suggests the ostensible increases in autism prevalence are "caused" by more accurate diagnosis.
But Willingham's piece adds a couple of new, interesting details to that still-emerging story. Being more aware of neurodiversity makes it look like there's more neurodiversity than there was before we were aware of it. And that was true even for the guy who invented the diagnosis of autism.
Leo Kanner first described autism almost 70 years ago, in 1944. Before that, autism didn’t exist as far as clinicians were concerned, and its official prevalence was, therefore, zero. There were, obviously, people with autism, but they were simply considered insane. Kanner himself noted in a 1965 paper that after he identified this entity, “almost overnight, the country seemed to be populated by a multitude of autistic children,” a trend that became noticeable in other countries, too, he said.
...by 1953, one autism expert was warning about the “abuse of the diagnosis of autism” because it “threatens to become a fashion.”
Read the rest of Willingham's piece, which includes a detailed look at several different studies that back up this view of autism with evidence. It looks like the majority of the "increase" in diagnoses can really be attributed to the process of diagnosis itself.
Spoiler is an independently produced 17-minute horror/science fiction movie that illuminates the kinds of cold equations that have to be solved in pandemic outbreaks. In this case, it's the story of the coroners who keep the zombie plague under control after it's been beaten back. It's a good twist on the traditional zombie movie, and hits a sweet spot of sorrow and horror that you get with the best zombie stories.
The zombie apocalypse happened -- and we won.
But though society has recovered, the threat of infection is always there -- and Los Angeles coroner Tommy Rossman is the man they call when things go wrong.
Under the Knife is the first collection of Brandon Seifert and Lukas Ketner's charmingly demented graphic novel Witch Doctor, which concerns th travails of Dr Vincent Morrow, a metaphysical epidemiologist who specializes in tracking down and eradicating transdimensional pestilences, ably assisted by Penny Dreadful (a possessed former art students whose internal demon feeds on pandimensional horrors) and Eric Gast, a paramedic who's learning the metaphysics trade.
Ketner and Seifert's sensibility is perfectly potty, and their titular doctor is a blend of Doctor Who and Spider Jerusalem. The metaphysics they reveal through the gruesome adventures in this volume has a weird internal consistency, but it's so cockeyed and frankly revolting that I can honestly say it never occurred to me before they scarred me with it.
This is a fine debut, and I can't wait for future volumes. Here's a preview of the first issue, and I've also included a few pages after the jump, so you can get a taste.
