In the village of Bellewstown, about 15 miles north of Dublin, Ireland, they still talk about what Barney Curley did back in 1975. It all happened during a horse race on the Hill of Crockafotha. It was just an amateur jockey race on a lazy summer day in a sleepy, remote town; it wasn’t meant to be anything special. The last thing anyone expected was to witness the making of history. The race in question occurred on 26 June 1975. Barney Curley–our protagonist, if you could call him that–owned one of the horses running later that day. But at the racecourse, as preparations were being made, Curley was nowhere to be seen. And not because he wasn’t in attendance–it was because he was taking great pains to stay out of sight. If the trackside bookmakers caught wind that he was at Bellewstown that day, or if they discovered that he was the owner of one of the horses, they would be on full alert, and take precautions with the wagers and odds. Curley had earned a reputation in horse racing circles–he was known to engage in some gambling shenanigans from time to time. But the shenanigan he was planning that day was his most ambitious to date, hands-down. As the spectators placed their wagers and settled in around the edge of the track for a pleasant afternoon of laid back horse racing, Curley was concealed in the thicket of gorse shrubs in the center section of the oval-shaped track. This particular infield wasn’t ideal for human occupation, it was all dust and thorns. Nevertheless he stood in his trademark felt fedora, shrouded by tall shrubbery, far from the other spectators, a pair of binoculars pressed to his eyes. In the distance the loudspeaker announced, “They’re off!” Curley tugged his hat down tight over his bald head as if he could hide inside of it, and peered through his field glasses toward the rumble of horse hooves. In the next five minutes, if everything went according to plan, all of Barney Curley’s considerable money troubles would be over. If the plan went sideways–if his animal was not up to the task, or there was one inopportune stumble–he would be utterly ruined. Continue reading ▶
Edmund Lawall must have felt cursed. He’d brought his family to New York in the late 1800s to carry on his father’s business as a pharmacist, but fate—or perhaps the city itself—seemed determined to drive him back out again. Lawall’s health had been in decline since their arrival, and his wife’s kidney disease had worsened, despite all of the tinctures and patent medicines available to his turn-of-the-century expertise. Not long after that, his business partner had been revealed as a crook, sending Lawall scrambling into bankruptcy court to convince the judge that his pharmacy had nothing to do with shady real estate dealings. Then, in the midst of the bankruptcy proceedings, an anonymous woman had staggered into Lawall’s drug store, collapsed on the floor, and died of unknown causes. Likely no one could have saved her, but it wasn’t exactly a ringing endorsement of the pharmaceutical services available at the corner of Eighth Street and Avenue C. None of that compared, however, to the morning of 27 June 1906, when a disheveled man in a medical coat burst through the narrow glass doors of the pharmacy, begging for protection. He was immediately followed by a young man with a revolver, and an angry crowd screaming in Yiddish. Lawall didn’t speak the language, but there was no mistaking the young man’s intent as he strode purposely forward and raised his gun to the doctor’s head. It was a grim, but recognizable tableau: the young man’s stance and grip were confident, clearly marking him as a budding gangster. The behavior of the crowd, on the other hand, made no sense at all. Innocent bystanders tended to run away from gang violence, yet the pushcart vendors and housewives surrounding the apparent holdup were not frightened, or even appealing for mercy. They were shouting, quite insistently, for the doctor’s execution. And everything seemed to indicate they were going to get what they wanted. In the weeks that followed, blame would be pointed in nearly every direction—because at that moment, unbeknownst to Lawall, similar scenes were playing out all over the neighborhood, with other doctors, teachers, reporters, and even utility workers being assaulted by hordes of people howling at them in Yiddish. By the time it was over, the incident would be measured as one of the largest riots ever in New York City, and the confrontation at Lawall’s Pharmacy would be mentioned only in passing, if at all. Another name, however, would be repeated over and over again: Adeline E. Simpson, the principal of Public School No. 110. Continue reading ▶
Iceland is known to the rest of the world as the land of Vikings and volcanos, an island caught between continents at the extremities of the map. Remote and comparatively inhospitable, it was settled only as long ago as the 9th century, and has seen little additional in-migration since. Even today, more than 90 percent of Iceland’s 390,000 residents can trace their ancestry back to the earliest permanent inhabitants, a Nordic-Celtic mix. The tradition of the Norse sagas lives on in the form of careful record-keeping about ancestry—and a national passion for genealogy. In other words, it is not the place to stumble upon old family mysteries. But growing up in the capital city of Reykjavík in the 1950s, neurologist Dr. Kári Stefánsson heard stories that left him curious. Stefánsson’s father had come from Djúpivogur, an eastern coastal town where everyone still spoke of a Black man who had moved there early in the 19th century. “Hans Jónatan”, they called him—a well-liked shopkeeper who had arrived on a ship, married a spirited woman from a local farm, and became a revered member of the community. The local census did record a man by the name of Hans Jónatan, born in the Caribbean, who was working at the general store in Djúpivogur in the 19th century—but that was all. No images of the man had survived, and his time in Iceland was well before any other humans with African ancestry are known to have visited the island. If tiny, remote Djúpivogur did have a Black man arrive in the 19th century, the circumstances must have been unusual indeed. It was an intriguing puzzle—and solid grounds for a scientific investigation. Given the amount of homogeneity in the baseline Icelandic population, the genetic signature of one relative newcomer with distinct ancestry might still stand out across a large sample of his descendants. Geneticists thus joined locals and history scholars, and they pieced together a story that bridged three continents. Continue reading ▶
It’s been a busy summer, and the large shortfall in donations last month has been demoralizing, so we’re taking a week off to rest and recuperate. The curated links section will be (mostly) silent, and behind the scenes we’ll be taking a brief break from our usual researching, writing, editing, illustrating, narrating, sound designing, coding, et cetera. We plan to return to normalcy on the 11th of September. (The word “normalcy” was not considered an acceptable alternative to “normality” until 14 May 1920, when then-presidential-candidate Warren G. Harding misused the mathematical term in a campaign speech, stating that America needed, “not nostrums, but normalcy.” He then integrated this error into his campaign slogan, “Return to Normalcy.” Also, the G in Warren G. Harding stood for “Gamaliel.”) While we are away, on 06 September 2023, Damn Interesting will be turning 18 years old. To celebrate, here are the first emojis to ever appear in the body of a Damn Interesting post: 🎂🎉🎁 If you become bored while we are away, you might try a little mobile game we’ve been working on called Wordwhile.

A few more interesting tidbits from the concluding half-day of the DOE ECMP PI meeting: Dmitri Basov showed some of the remarkable experiments enabled by layers of MoOCl2, which in the IR is an intrinsically hyperbolic optical material. This material has unusual plasmonic properties considering its high resistivity. These include peculiar cavity effects such as modifying superfluid density of a proximally coupled superconductor. Leonid Butov explained some remarkable evidence for superfluidity of indirect excitons excited in the moire bilayer of MoSe2/WSe2. Low temperature mean free paths of these objects can exceed hundreds of microns (!). Cui-Zu Chang showed evidence that truly stoichiometric FeTe is actually a superconductor with a critical temperature of about 13.5 K, rather than the usual thinking that it is an antiferromagnetic metal. Apparently an extra 2% of interstitial iron is enough to kill superconductivity and induce AFM order. James McIver presented an example of how nonlinear optical effects in an optically driven (Floquet) Weyl semimetal seem to vary linearly with driving field - anomalously strong. Dmytro Bozhko showed a really neat technique, using Brillouin light scattering to map out the dispersion of phonons and magnons in YIG, and to extend this approach with a special hollow-core optical fiber to low temperatures with the motivation of probing magnon superfluidity in a particular antiferromagnetic insulator. Ray Ashoori used his characteristically pretty quantum capacitance measurement technique to examine the density+displacement field+magnetic field phase diagram of 5-layer rhombohedral graphene, revealing some surprising fractional Chern insulator states. Claudia Ojeda-Aristizabal discussed some mesoscopic transport measurements in bilayer graphene, where an adsorbed layer of spin-containing CuPc molecules seems to affect both decoherence and the trigonal warping contribution to it (related to intervalley scattering). Feng Wang and You Zhou both discussed recent measurements looking at Wigner crystals and their properties in 2D TMDs, through a variety of means. Liuyan Zhao showed some very rich physics obtained in studies that moiré stack bilayers of the van der Waals insulating magnet CrI3. Unfortunately I missed the last talk because of the need to head to the airport. Overall, the meeting was very good. Program PI meetings can tend to become less about telling coherent scientific stories and more about trying to show everything someone has done in the last three years. This meeting avoided that, with clear talks that generally focused on one main result, and that made it much more engaging. As good as tools for virtual gatherings have become, there really is no substitute for an in-person event when you can just talk to someone by the coffee about some new idea.
Western wildfires are producing massive plumes of smoke that have, in recent years, clouded eastern skies. But a new study finds that, paradoxically, heat from fires is reshaping weather patterns in ways that are actually improving overall air quality on the East Coast. Read more on E360 →
