In this edition: Bad medicine, imperfect sound forever, know when to fold ’em, brainiacs, and a call of the wild.

Showcasing stories from Andrew Fedorov, Shayla Love, Malcolm Johnston, Erin Somers, and Chris Stanton.

Carleton Gajdusek won the Nobel Prize for his work on a disease in Papua New Guinea. But his biggest experiment was on the children he took from the field to the US—many of whom he sexually molested, with the knowledge and, in some cases, approval of his professional peers and colleagues:

In his journals and in letters to colleagues, Gajdusek was self-righteous, arguing that what he’d done was “no more serious than lying on the grass or picking a dandelion,” and he cited the Anga initiation rites as justification. These ceremonies had brought boys into their communities, as part of a shared passage into manhood, but Gajdusek treated them as a timeless license for the acts that he’d committed privately, one boy at a time. George Klein, a professor at the Karolinska Institute, in Stockholm, who was part of the Nobel Assembly for thirty-six years, validated Gajdusek’s opinions, telling him that he wondered if “the Western world can ‘catch up with you.’” He wrote, “I share your indignation about the typically Jewish-Christian-Moslem hypocrisy on sexual matters.” Gajdusek was troubled, though, by how many colleagues wrote letters saying that they knew the charges must be untrue. “I thought better of my friends,” he said. “They are dissimulating and lying.”

For The New Yorker, Shayla Love writes about how GPS—a military technology turned daily necessity, and the subject of Katherine Dunn’s new book, Little Blue Dot: How GPS Shaped the Modern World—has changed the way we move through the world. To test her own skills, Love navigates from North Brooklyn to a park in Queens with a paper map, then sets off on an orienteering course without the trusty little blue dot, where she discovers how rusty her sense of direction really is.

Surprisingly, I still felt an urge to pull out my phone and look at my dot, to confirm what my surroundings were showing me. I started to feel that the true value of orienteering was more akin to that of reading a long book, or baking from scratch, or attending a long classical-music concert. I wasn’t necessarily tapping into my inner homing pigeon. I was practicing more general skills that get rusty when I over-rely on technology: paying attention, being patient, accepting uncertainty. We made our way to No. 7, on a “prominent tree, east side.” We didn’t find No. 6—a small blow to the ego—but my confidence soared when we found five, four, and three. The desire to check my dot faded to a low simmer.

Stormy Morse lost two partners to gun suicide. She didn’t know that the second one, Lewis Tabler, had made the National Rifle Association the beneficiary of his retirement savings through its planned-giving program. In this feature, co-published with The New Yorker, Mike Spies describes what happens when the NRA, which has long denied a connection between access to guns and suicide rates, comes to collect:

Fisher, the NRA’s planned-giving director … e-mailed Applied Industrial, pointing out that Tabler had been dead for two months, and that “accounts with properly designated beneficiaries” are “generally available for distribution within 7–10 business days.” He went on, “We want to do whatever is needed to make this a smooth process.”

Meanwhile, multiple debt collectors had filed claims against Tabler’s estate, and the register of wills informed Stormy that she also owed an inheritance tax, since she was now the sole owner of the home.

As a favor, a neighbor of Stormy’s who was a lawyer spoke to the NRA’s assistant general counsel, Sarah Gervase, on her behalf. The neighbor raised the possibility that the organization might give up some of the money, according to Gervase, who recounted the exchange in an e-mail with Applied Industrial in early June. Gervase wrote that she “informed” Stormy’s neighbor that the “NRA is not willing to settle this.” Tabler’s cause of death did not seem to have any bearing on the organization’s position.

War stories, new colors, and the joy in getting hands on in art and gardening.

Ready to test your knowledge of hue, value, and saturation? Rivka Galchen’s latest for The New Yorker is a trove of fascinating details about our understanding of color. Galchen opens with the buzziest tidbit: an experiment conducted by a vision scientist who used a laser to stimulate a selection of his own cone cells and glimpse a color unknown outside of his laboratory. From there, she roams—through philosophy and art history, from studios to pigment shops—complicating our understanding of perception with each new turn of her titular question.

In the children’s novel “The Midnight Fox,” by Betsy Byars, the main character daydreams about digging in his back yard and coming across a “brand-new color.” A friend of mine remembers being captivated by this scene, and trying to picture the color. “I felt like I could conceive of it, but I couldn’t see it,” she said. The eighteenth-century Scottish philosopher David Hume considered at length whether a person who had seen every shade of blue except for one would be able to picture that one un-experienced shade; he concluded that the answer was yes. In my youth, I spent an afternoon wondering if I would have been able to imagine the fluorescent yellow of highlighter markers if I’d never seen it.

In this edition: in a pickle; gut feeling; king of pain; life (or something like it); for those about to rock.

What moves the star of Jackass to risk his life for our entertainment? This “very serious investigation” involves interviews with friends and family, a surf trip to Malibu, a gag with a fake raccoon, and a stop at In-N-Out:

He nosed the car into the drive-through line, drawing stares as he nosed—some for the vehicle, some for the driver. Mostly male stares. A teen-age boy stepped up to the passenger window and leaned in to take his order.

“One hamburger with tomato, lettuce, and mustard,” Knoxville said. “Fries, please. And a cup of water.”

“Onion?”

“No, sir.”

The teen-ager squinted. “You look familiar. Are you famous, by any chance?”

“Actually, completely by chance!” Knoxville improvised.
