- Nothing for WATCH until The Count of Monte Cristo at Aldersgate this fall.
- I’ll be reading scripts for AACT’s NewPlayFest 2020.

“When L died, our teacher said, Every time you think of her, give something away, or, do something kind. And I said, Then I’d be giving things away non-stop. And he said, So?”

Dogs as hosts are presenting an obstacle to eradication of Guinea Worm disease, reports Michaeleen Doucleff. There’s a possibility that dogs are being infected by eating frogs. Your parasitology WOTD is paratenic; the frogs would be paratenic hosts, not obligate for the development of the parasite but serving to maintain the life cycle.
Not yet in commercial production but promising: a tabletop device that can detect gluten proteins in food at the 5 ppm level in 120 seconds.
Cryptococcal meningitis is a debilitating and lethal fungal disease that afflicts persons with compromised immune symptoms. Of the many neglected diseases, tropical and otherwise, it may be the most overlooked.
There is no day named for its awareness, no celebrity ambassador to champion its demise. The World Health Organization (WHO) team tasked with addressing cryptococcal meningitis is a team of one.
That’s also the number of times cryptococcal meningitis is mentioned in the 500-plus pages of the latest UNAIDS report.
Not since 2009 has it been mentioned in The New York Times.
Immuno Mycologics in Norman, Okla. is developing an assay that can detect the disease while it’s still at treatable stages in its progress.
Patrick Adams has the report.
Worldwide cases of Guinea worm have been reduced by 5 orders of magnitude in the span of 30 years: one human generation. And a lot of the credit goes to The Carter Center, established by former President Jimmy Carter and his wife Rosalynn.
Perhaps most astonishingly, the disease is facing eradication due to public health education and dirt-cheap technology: water filters. Chew on that, Big Pharma.
[Trevor] Pinch has made a career of studying how scientists listen. He notes that listening has certain advantages over vision. “The visual field is kind of in front of us — like a kind of screen,” he says, while sound is “all around.”
If seeing is like being in an art gallery, hearing is more like being in a swimming pool — where we’re swimming all the time.
Jimmy Carter talks to Diane Cole about his and Rosalynn’s work to eradicate Guinea worm disease.
Our main commitment at the Carter Center is to fill vacuums in the world. We don’t duplicate what others are doing. If the World Health Organization or the United Nations or the United States government or [other organizations] are doing work, we don’t get involved. We tackle problems that other people aren’t addressing.
To merely report, or to become personally involved, perhaps putting oneself at deathly risk: a classic conundrum of journalism. Jeffrey Gettleman unpacks his own hard choice.
In so many stories I’ve covered about people in need, I struggle with when to step back, when to help out, how to be a so-called impartial observer, as I’m paid to be, but at the same time remain a decent human being. Here I failed.
Catching up on a lot of bookmarks, so this will be a bit of a link dump.
- Reduced-meat or meatless diets (Mediterranean, pescetarian, vegetarian) are both better for your health and more sustainable for the environment, as David Tilman and Michael Clark find in a recent paper, and as Elke Stehfest summarizes.
- I am loving Nature‘s new sharing tools. Susannah Locke explains the journal’s move toward more open access.
- Emily Dreyfuss signed up to give Wikipedia six bucks a month.
…Wikipedia is the best approximation of a complete account of knowledge we’ve ever seen.
It’s also the most robust. The most easily accessed. And the safest. It exists on servers around the world so, unlike the library at Alexandria, it can’t be burned down.
- The Biodiversity Heritage Library has opened an online exhibit dedicated to women in science who began working before 1922. Some of my recent subjects are there, including Florence Merriam Bailey and Mabel Osgood Wright.
Reporting on the recent FDA food labeling standard for gluten-free foods, Allison Aubrey does a great job of unpacking the various consumer constituencies who care about gluten in their diet. The blog post doesn’t dwell on this point, so listen to the audio from the All Things Considered two-way with Audie Cornish. Aubrey identifies three groups:
- people who are on the gluten-free bandwagon and will fall off eventually;
- people who experience gluten sensitivity, who do better avoiding wheat and related grains, but can tolerate a little or a lot;
- people with true-blue celiac disease.
Aubrey identifies the third group as those for whom gluten is a real problem, not just something to be avoided casually. These are the three million people who, in her deft description for radio, suffer from a “chronic auto-immune disorder that can destroy the lining of the small intestine… even a little gluten can make them sick.”
An editorial from Scientific American points out that executions by lethal injection are putting innocent patients at risk. The supply of tranquillizers like propofol (used in routine procedures like colonoscopies), all or in part, comes from Europe, and the E.U. prohibits export of drugs that are to be used to kill people.
Perhaps the root problem is here:
…executions are not medical procedures. Indeed, the idea of testing how to most effectively kill a healthy person runs contrary to the spirit and practice of medicine. Doctors and nurses are taught to first “do no harm”; physicians are banned by professional ethics codes from participating in executions. Scientific protocols for executions cannot be established, because killing animal subjects for no reason other than to see what kills them best would clearly be unethical. Although lethal injections appear to be medical procedures, the similarities are just so much theater.
Jennifer Richler posts a good piece about what to expect from good popular science writing—and what to expect from yourself, the reader.
…when you finish reading a piece of science writing, you [should not] think, “‘Wow, I better make some serious changes to the way I eat/talk to my children/use my credit cards,’ but rather ‘Hmmm, I wonder how likely it is that this advice will turn out to be worth following.’” That curiosity should spur you to seek out good information continually. Over time, if the research appears to converge on a particular conclusion—the overwhelming consensus that there is no link between autism and vaccines, for example—then you should probably take it seriously.
Just when I think that I have run out of indignant, that I am fresh out of appalled, I come across a story like this: In an effort to determine the precise whereabouts of Osama bin Laden (preparatory to the extrajudicial killing, assassination, whatever you want to call it, of this monstrous person), the Central Intelligence Agency put together a fake hepatitis B vaccination clinic and went about collecting DNA in the Abbottabad, Pakistan neighborhood where bin Laden was suspected to be holed up. As the editors of Scientific American put it,
It is hard enough to distribute, for example, polio vaccines to children in desperately poor, politically unstable regions that are rife with 10-year-old rumors that the medicine is a Western plot to sterilize girls—false assertions that have long since been repudiated by the Nigerian religious leaders who first promoted them. Now along come numerous credible reports of a vaccination campaign that is part of a CIA plot—one the U.S. has not denied.
The likely wages of this shameful sin is the stalling of global efforts to eradicate polio, as Donald G. McNeil, Jr.’s reporting for the New York Times suggests. A certain Dr. Shakil Afridi is identified as being in charge of the fake medical exercise. Instead of administering the full three doses of vaccine that are called for in the protocol, the ersatz humanitarians abandoned the setup after giving one dose to everyone in an entire neighborhood, without permission. Bad medicine, reprehensible spycraft, irresponsible policy.
From last summer, Joe Palca’s two-parter (one, two) about Scott O’Neill’s 20-year efforts to find a biological means to control and eventually eliminate dengue fever. I like the focus of Palca’s series: it’s not just about the newest published scientific results, it’s about the process of doing science.
“You know, I was incredibly persistent in not wanting to give this idea up,” O’Neill said. “I thought the idea was a good idea, and I don’t think you get too many ideas in your life, actually. At least I don’t. I’m not smart enough. So I thought this idea was a really good idea.”
