Science writer Mary Roach is not effortlessly repulsed. Even though researching her newest book, Grunt, Roach learned all about the medicinal use of maggots in World War I. She also purposely sniffed a putrid scent identified as “Who me?” that was created as an experimental weapon during Globe War II.

For Roach, it really is all in the name of research. “I am sort of the bottom-feeder of science writing,” Roach jokes to Fresh Air‘s Terry Gross. “I’m just an individual who is OK with being quite out there with my curiosity.”

Roach’s curiosity compelled her in previous books to dive deep into the science of cadavers, sex and digestion. Now, in Grunt, she examines the science of warfare — especially some of the scientific developments that help stop wounds from becoming infected, and enhance the chances that soldiers will endure the heat of the desert and survive explosions.

On combating the issue of diarrhea in the military

It’s specifically serious among unique operations service members — Army Rangers, Navy SEALs, people who are operating off the primary bases in really remote rural regions in villages where there isn’t a secure water provide. They may be eating meals that is been contaminated by flies, not refrigerated, so they’re obtaining diarrhea at a rate that’s twice what the typical enlisted person is acquiring.


And the typical enlisted particular person — there was a study carried out, I think it was 2003 to [2004] and they asked folks, “How frequently did you come down with diarrhea, and what type?” Seventy-some percent had diarrhea — 40 % negative adequate that they sought health-related remedy, and 32 % had been in a scenario where they couldn’t get to a toilet in time.

You could picture if you have been a specific operations team, like three or 4 men and women going to do some hugely classified crucial mission exactly where you can not truly stop and say, “Hold on, I got to go behind that rock.” …

The researcher that I accompanied at Camp Lemonnier [in Djibouti] is Capt. Mark Riddle, who is with the Navy, and he’s searching at a far better remedy regimen for traveler’s diarrhea, which can really put you out of commission for a even though. He’s hunting at a one particular-dose regimen, rather than 3 or four days it was anything that you could take, and inside the day start off to be feeling much better and be more than it.

On maggots employed to clean and heal wounds throughout WWI

This was a battlefield in Planet War I, and there was a healthcare man, William Baer, with the French expeditionary forces, and he noticed that a couple of his individuals had come in with these wounds on the legs and on the genitals. They had been out in the field for seven days. They’d been lying there, they have been brought in, and the wounds were infested with maggots. …

Initially there was that revulsion of, “Oh my God we’ve got to clean them out.” And they did clean them out, and then what he saw was this lovely pink, new, fresh tissue that had grown in.

The maggots had been impressively successful at debriding the wound — that is, consuming the dead tissue — which is crucial in wound healing. You want to let the fresh tissue have a chance to grow. The dead tissue doesn’t get blood it doesn’t heal. It stands in the way of healing.

The maggots also seemed to prevent infection … so it was this kind of miraculous feat that the maggots had achieved. And William Baer some years later, back in civilian life, he kept pondering about this and he thought, “I’m going to attempt this.” There were some children with bone infections — it was TB infection of the bone — and he attempted the maggots, and it worked.

You can envision that was a pretty brave issue to do, to place maggots in these children’s wounds. But they have been wounds that had not responded to other therapy or surgery, and it in fact worked. There’s perform going on nonetheless today with maggot therapy, as it really is known as. Really, the FDA has authorized maggots as a healthcare device. … I can actually inform you the Medicare reimbursement quantity for maggots.

On the problem of employing maggots in modern hospitals

Not only is there a revulsion issue that you have to overcome with the employees — the nurses are going to have to go in — you are going to have to clean the maggots out after a couple of days. You do not want them to pupate, turn out to be flies, due to the fact you consider, flies flying around a hospital is the last thing you would ever want, simply because a fly can spread illness from landing on material in the bathroom and then landing on a wound. It’s the final point you’d want in a hospital, so you have to be cautious employing maggots. …

They’re not any old maggots. They’re a particular sort of bottle fly. They’re from a business called Healthcare Maggots. They come with a dosage card — it is something like five to eight maggots per such-and-such square centimeters. … They come in a vial, type of like drugs. You never want to just sort of attract any kind of fly to come and lay eggs in a wound. That would be a tiny dicey. … You require a prescription, although!

On the usage of stink bombs for the duration of WWII

I use the term “stink bomb” sort of casually … this was far more specifically a … squirtable spray, or a smearable paste. The idea was to get this very easy, low-cost weapon into the hands of resistance organizations. Individuals in occupied nations — France, China — give it to them, and they would surreptitiously approach officers, German or Japanese officers, and squirt this little 2-inch tube of this quite heavily researched and tested, quite foul-smelling odor, which was nicknamed “Who Me?” as in “Who dealt it.” So it was a sort of surreal and bizarre chapter in the history of Planet War II. …

The thought was to give motivated citizens things that they could very easily and cheaply use to undermine morale, to isolate, humiliate these officers. It’s a quite little gesture it wasn’t going to turn the tide of war. And in truth, “Who Me?” — this smell paste — was by no means deployed. The project went on for two years. And a lot of testing went on, since of a tremendous quantity of difficulty with the delivery method. The tubes tended to leak and dribble, and then the operator, himself or herself, would have this stench on their hand. … It was a bit of a fiasco.

On the ongoing study to find a universal poor smell for stink bombs

There’s nevertheless function that goes on. Monell Chemical Senses Center in Philadelphia has accomplished perform more than the years on malodorants. They designed one particular named “Stench Soup.” …The Joint Non-Lethal Weapons Directorate, back in the ’90s, commissioned them to come up with a universally loathed scent, simply because there are some cultural variations. They really looked into different cultural reactions to the scent of vomit, of burned hair, of dirty feet, all of these different odors to see, “Can we find 1 that is universally loathed?” And then we could use that in any military setting, in any nation, in any culture. It really is very difficult to do. If you don’t know what you are smelling — for example, butyric acid, depending on the context, might smell like smelly feet or it may smell like Parmesan cheese, just completely depends on the context, whether or not you feel it smells very good or negative. …

I truly have, in a box in my closet, a sample of “stench soup.” It’s in a bottle that is double bagged and sealed with paraffin and packed in a box and I haven’t had the courage to open up, since the last time I opened up some thing that came from the Monell Chemical Senses Center, which was an old archival sample of “Who Me?” and I opened it up out on the deck, it was quite some time prior to anybody could go out on the deck. I really gagged. As you can imagine, I’m not very easily repulsed or … disgusted.
