From Undark: “Nuclear weapons laboratories don’t often help solve serial-killer cases. But in the investigation of Efren Saldivar, data from such a lab provided the clinching evidence that led to his conviction on six counts of murder. As a respiratory therapist at Glendale Adventist Medical Center in California, Saldivar helped care for terminally ill patients. The hospital got a tip that someone had “helped a patient die fast,” and Saldivar was questioned. He confessed to dozens of murders, stating that he poisoned patients with overdoses of the paralyzing chemicals pancuronium bromide, also known as Pavulon, and succinylcholine chloride. He was arrested immediately. But there was little physical evidence to back up his self-incriminating claims.”

The difficulty markings for ski hill runs were designed by Walt Disney

From Inside The Magic: “If you have ever visited a ski resort in the United States or Canada, a significant part of your experience is thanks to work done by Walt Disney and his team. And you probably had no idea. All ski resorts in North America grade their slopes and trails with either a green circle (easy), a blue square (intermediate), a black diamond (advanced), or a double black diamond (experts only). It was Walt Disney’s team that came up with that grading system. Before he passed away in 1966, Disney set out to build or buy his own ski resort. One of the proposed locations was in California’s Sequoia National Park, but environmentalists reportedly blocked it. But before the plan was shut down, Disney already established its proposed trail signage.”

From Sky News: “Dr Cara Love, an evolutionary biologist and ecotoxicologist at Princeton University, has been studying how the Chernobyl wolves survive despite generations of exposure to radioactive particles. Dr Love and a team of researchers visited the CEZ in 2014 and put radio collars on the wolves so that their movements could be monitored. They also took blood samples to understand how the wolves’ bodies respond to cancer-causing radiation. The researchers discovered that Chernobyl wolves are exposed to upwards of 11.28 millirem of radiation every day for their entire lives – which is more than six times the legal safety limit for a human.”

A Liverpool man who inherited $125,000 let 12 strangers decide what to do with it

From The Guardian: “A man who has been sitting on a £100,000 inheritance from his mother for more than 10 years has given the large sum to four charities in Liverpool, and that decision was down to 12 strangers. David Clarke, 34, said he wanted to tackle inequality as he felt he had enough money to live on. He wanted to give power to his neighbours and residents to decide what to do with his lump sum of money. So he sent letters randomly to 600 addresses in the L8 postcode, and then picked 12 to take part in the project. “During the first session, everyone thought it was a scam,” Clarke said, “but when the facilitator and I explained the cause and backstory, it was fine.” The only condition he gave to the group was not to spend the money on themselves.”

Last July, Meta launched Threads, a new social network it hoped would compete with X (formerly Twitter), and within twenty-four hours the new app had hit thirty million sign-ups; a few months later it would have almost a hundred million monthly users, according to Mark Zuckerberg, Meta’s CEO. Not long after it launched, however, Adam Mosseri—the man in charge of both Threads and Instagram—sparked some controversy by describing how Threads would handle news, including political topics. In a nutshell, he said that while users were free to post and discuss news and politics, Threads was “not going to do anything to encourage” that kind of content. In other words, news and politics would not be recommended by the Threads content algorithm.

The controversy Mosseri triggered with these remarks resurfaced this week, when he posted an update on Threads’ approach to political news and user accounts. If a user followed political accounts on either Threads or Instagram, he said, Meta would do its best to “avoid getting between you and their content”—but at the same time, Mosseri said, the company remained focused on how to avoid recommending such content in various places across the app. The result, he added, is that political news topics and accounts will not show up as recommendations in any of the app’s features, including Explore, Reels, and Suggested Users. (Mosseri noted that if users wanted to see political recommendations, there would be a way to opt in.)

Mosseri and other Meta spokespeople described these moves as consistent with the company’s existing approach to political content, as described in a Meta blog post. “People have told us they want to see less political content,” the post states, and so the company has spent “the last few years” reducing the amount of such content that users see in their feeds or in recommendations. Meta does this, it said, because its policy is not to recommend certain types of content “to those who don’t wish to see it.” The company told Axios that anyone who discovers that their account is blocked from being recommended can request a review of this decision or “stop posting this kind of content for a period of time” in order to be eligible to be recommended again.

From Atlas Obscura: “She’s been called the greatest female explorer of all time, and the best-traveled woman of the Middle Ages. Just after the year 1000 AD, she gave birth to the first European baby in North America. And she concluded her global odyssey with a pilgrimage on foot to Rome. Yet few today can name this extraordinary Viking lady, even if they have heard of Erik the Red and Leif Erikson, her father- and brother-in-law. Her full name, in modern Icelandic, is Guðríður Þorbjarnardóttir—Gudrid the Far-Traveled, daughter of Thorbjorn. She was born around 985 AD on the Snæfellsnes peninsula in western Iceland and died around 1050 AD at Glaumbær in northern Iceland.”

This unassuming suburban couple had a $160 million painting in their bedroom

From the Smithsonian: “She was a retired speech pathologist, and he was a retired music teacher. For all intents and purposes, Rita and Jerry Alter were a totally normal couple living in the New Mexico suburbs—except for one thing. They had a stolen Willem de Kooning painting worth $160 million hanging behind their bedroom door. The couple has never been officially linked to the artwork’s theft from the University of Arizona. According to the university, a man and a woman entered the museum around 9 a.m. on November 29, 1985. While the woman spoke with a security guard, the man went up to the second floor, where he cut the painting from its frame, rolled it up and hid it under a garment.”

From the Financial Times: “Last year, Norway’s $1.5tn sovereign wealth fund revealed that it had lost NKr980mn, roughly $92mn, on an error relating to how it calculated its mandated benchmark, which led to a marginal overweight in US fixed income relative to global fixed income. In a recent report, the fund revealed the source of the mistake: a staffer named Simon entered the date December 1st instead of November 1st when calculating the fund’s benchmark, which threw off the calculations. The mistake wasn’t found until months later by the Norwegian Ministry of Finance, which audits the fund’s performance. Could this be the most consequential Excel spreadsheet error ever?”

The long and surprising legacy of the Hopkinsville Goblins

From Atlas Obscura: “In August 22, 1955, a Kentucky newspaper reported strange goings-on north of Hopkinsville. Two cars arrived at the local police station, filled with at least five adults and several children, all of whom were highly agitated. They unfurled a strange story: a circular-shaped object came to rest in a nearby gully, and a strange, goblin-like thing with glowing eyes appeared and moved toward him. Steven Spielberg was told about the case by J. Allen Hynek, an astronomer turned UFO researcher whose work gave Close Encounters of the Third Kind its title, and the story not only helped inspire what became the movie E.T., but also the movie Gremlins, and the film Poltergeist.”

From the MIT Press: “One of the most unusual chapters in psychiatry behind the Iron Curtain concerns the use of LSD psychotherapy in 1960s Czechoslovakia. Until recently, this period was known mainly through the work of Stanislav Grof, who practiced at Prague’s Psychiatric Research Institute, moved to the U.S. in 1967, and is today celebrated as one of the founders of transpersonal psychology. But dozens of other Czech psychiatrists also used LSD in psychotherapy, and the most dedicated and outspoken of them was Hausner, who supervised more than 3,000 LSD sessions, published research in more than 100 articles and books, and yet remains largely unknown, even in his homeland.”

Archeologists have found a vast network of cities hidden under the Amazon jungle

From the BBC: “Using airborne laser-scanning technology, Rostain and his colleagues discovered a long-lost network of cities extending across 300 sq km in the Amazon, complete with plazas, ceremonial sites, drainage canals and roads that were built 2,500 years ago and remained hidden for thousands of years. They also identified more than 6,000 rectangular earthen platforms believed to be homes and communal buildings in 15 urban centres surrounded by agricultural fields. Most of what we think we know about the Amazon is wrong, says Rostain. “This forces us to rethink the entire human past of the Amazon.”

From The Atlantic: “Plenty of everyday objects, from ceramics and glass to metals and bananas, are radioactive, to varying degrees. Should the particles from their decay hit the detectors of particle-physics experiments, they could give scientists false positives and dig potholes on the road to scientific discovery. Even the experiments themselves, built from all kinds of metals, have lightly radioactive components. Just a few inches of lead can shield detectors from all kinds of rogue radiation, and one of the best ways to block sneaky, unwanted particles is to surround them with lead that itself is barely radioactive. The best source of such lead just so happens to be sunken ships, some of which have been corpses near coastal waters for as long as two millennia.”

She’s 116 years old and her entire town has become her family

From the New York Times: “When Edith Ceccarelli was born in February 1908, Theodore Roosevelt was president, Oklahoma had just become the nation’s 46th state and women did not yet have the right to vote. At 116, Ms. Ceccarelli is the oldest known person in the United States and the second oldest on Earth. She has lived through two World Wars, the advent of the Ford Model T — and the two deadliest pandemics in American history. For most of that time, she has lived in one place: Willits, a village tucked in California’s redwood forests that was once known for logging but now may be better known for Ms. Ceccarelli. At Willits City Hall, where 100-foot redwoods tower overhead, a gold-framed photograph of Ms. Ceccarelli sits in a display case.”

From Mary Spicuzza for the Milwaukee Journal: “Florence Grady and Augie Palmisano reached the elevator doors at the same time. Both were tenants at Juneau Village Garden Apartments in downtown Milwaukee. And shortly before 9 a.m. that Friday — June 30, 1978 — both were heading to the basement of the apartment complex. They chatted about the weather and Summerfest. When they reached the basement, he walked to his car, a 1977 Mercury Marquis. Less than a minute later, there was a massive explosion. The blast shook the city. Paintings fell from walls and books tumbled off shelves. Tenants ran from the building as firefighters and police rushed to the scene. Augie Palmisano was my cousin. His murder has never been solved.”

The Black female engineer who played a pivotal role in developing GPS

From Tanasia Kenney for the Atlanta Black Star: “From cell phones to cars and even social media, most folks in this day and age are familiar with the Geographical Positioning System, or GPS. Little known is the fact that an African–American woman mathematician was a part of the original team of engineers tasked with developing the highly useful system. West, 87, enjoyed a 42-year career as a mathematician at the Naval Support Facility in Virginia where she, and fellow engineers saw the early beginnings of the popular tracking system. She was just one of four Black Americans employed at the base when she first started in 1956, her calculations eventually leading to GPS satellites.”

Last week, executives from some of the world’s largest social platforms—Meta, which owns Facebook and Instagram, as well as TikTok, Snap, Discord, and X, formerly known as Twitter—testified at a Senate hearing about children’s safety online. The session featured the sort of grandstanding by senators that often occurs in such hearings, including a bizarre detour into whether Shou Zi Chew, the CEO of TikTok (which is based in China), is a member of the Chinese Communist Party (even though he is from Singapore). One particularly striking moment came after Josh Hawley, the Republican senator from Missouri, asked Mark Zuckerberg, the CEO of Meta, to apologize to some of the families present at the hearing, including Maurine Molak, whose son David died by suicide at sixteen after he was cyberbullied, and Todd and Mia Minor, whose son Matthew died at twelve after he took part in an online “blackout challenge.” Zuckerberg complied. “No one should have to go through the things that your families have suffered,” he said.

Parents in the viewers’ gallery, including Molak and the Minors, weren’t just there for an apology from Zuckerberg or the other executives, but to pressure legislators to pass the Kids Online Safety Act, a law that, according to its supporters, could help prevent the kinds of dangers that their children were exposed to. Molak told NBC News that she and other parents are up against a “billion-dollar lobby campaign” funded by the tech platforms and aimed at blocking the legislation. She added that she and the other parents in attendance are “sick and tired of [tech platforms] deploying all of these people to crush the work that we’re doing.”

KOSA was first proposed in 2022 by Richard Blumenthal, the Democratic senator from Connecticut, and Marsha Blackburn, the Republican senator from Tennessee. Blumenthal has said that he was inspired to craft the legislation after Frances Haugen—a former Facebook staffer turned whistleblower, whose disclosures from inside the company were widely covered by numerous major news outlets in 2021—appeared before Congress that year. As part of her testimony, Haugen submitted internal documents that appeared to show that bosses at Meta knew that Facebook and Instagram were harming teenagers, by encouraging emotionally or physically harmful behavior, but had taken little or no action to prevent by way of mitigation. Blumenthal said that KOSA was necessary because Haugen had showed that Facebook knowingly “exploited teens using powerful algorithms that amplified their insecurities.”
