Xuehu Wei, who is a doctoral student in the research team around Alfred Anwander and Angela Friederici, compared the brain scans of 94 native speakers of two very different languages and showed that the language we grow up with modulates the wiring in the brain. Two groups of native speakers of German and Arabic respectively were scanned in a magnetic resonance imaging (MRI) machine. The high-resolution images not only show the anatomy of the brain, but also allow us to derive the connectivity between the brain areas using a technique called diffusion-weighted imaging. The data showed that the axonal white matter connections of the language network adapt to the processing demands and difficulties of the mother tongue. “Arabic native speakers showed a stronger connectivity between the left and right hemispheres than German native speakers,” explained Alfred Anwander, last author of the study.

Scientists discover RNA component buried in the dust of an asteroid

A sample extracted from an asteroid far from Earth has confirmed that RNA nucleobases can be found in space rocks. Analysis of dust ferried home from asteroid Ryugu has been found to contain uracil – one of the four nucleobases that make up RNA – in addition to niacin, a form of the vitamin B3, which plays an important role in metabolism. This adds to a growing body of evidence that the building blocks for life form in space, and may have been at least partially delivered to Earth by asteroid bombardment early in our planet’s history. “Scientists have previously found nucleobases and vitamins in certain carbon-rich meteorites, but there was always the question of contamination by exposure to the Earth’s environment,” says astrochemist Yasuhiro Oba of Hokkaido University in Japan. “Since the Hayabusa2 spacecraft collected two samples directly from asteroid Ryugu and delivered them to Earth in sealed capsules, contamination can be ruled out.”

In the 1800s, counterfeiting became extremely common, and the one person acknowledged as America’s greatest counterfeiter was Benjamin Boyd. Boyd used to work for a Chicago syndicate run by James “Big Jim” Kinealy. However, Abraham Lincoln’s legislation to arrest counterfeiters resulted in Boyd being sentenced to prison in 1876. With Big Jim’s top man gone, his business was in a wrecked state. He had to do something to get Boyd freed from prison. Out of the blue, a bizarre plan arose: steal Abraham Lincoln’s body, bury it in the Indiana dunes, and then ask for $200,000 for ransom along with the pardon and freedom of Benjamin Boyd. To execute this plan, Kinealy hired a bartender, Terrence Mullen, and a counterfeiter, Jack Hughes. The two decided to pull off the heist on election night when no one was in town. There was also very minimal security at Lincoln’s grave, which meant the chances for the plan to go wrong were significantly less.

Why did the US government amass a billion pounds of cheese?

The year was 1981, and President Ronald Reagan had a cheese problem. Specifically, the federal government had 560 million pounds of cheese, most of it stored in vast subterranean storage facilities. Decades of propping up the dairy industry—by buying up surplus milk and turning it into processed commodity cheese—had backfired, hard. The Washington Post reported that the interest and storage costs for all that dairy was costing around $1 million a day. “We’ve looked and looked at ways to deal with this, but the distribution problems are incredible,” a USDA official was quoted as saying. “Probably the cheapest and most practical thing would be to dump it in the ocean.” Instead, they decided to jettison 30 million pounds of it into welfare programs and school lunches through the Temporary Emergency Food Assistance Program. But the surplus was growing so fast that 30 million pounds barely made a dent. By 1984, the U.S. storage facilities contained 1.2 billion pounds, or roughly five pounds of cheese for every American.

About two weeks after his 18th birthday, Dallas Seavey became the youngest competitor to ever finish the Iditarod; at 25, he became the youngest to win it. But his fifth victory, in 2021, carried an asterisk: He triumphed on a truncated 848-mile course, shortened to prevent the potential spread of Covid. To the sport’s critics, however, no amount of victories can erase their perception of Dallas’s wrongdoings. As he and his father came to dominate the Iditarod, they also became ensnared in a long-running debate about the very nature of dog sledding. Are huskies at their happiest running hundreds of miles a week, as mushers maintain? Or, as animal rights activists insist, are they victims of callous human ambition, sometimes required to endure unfathomable hardship? The conflict has embroiled both the Iditarod and the Seaveys in a fight that could change the sport forever—and, if some have their way, maybe even lead to its demise.

Traveling with the King of Caterpillars

David Wagner specializes in caterpillars, or, it might be more accurate to say, is consumed by them. (They are, he suggested to me, the reason he is no longer married.) Probably he knows more about the caterpillars of the U.S. than anyone else in the country, and possibly he knows more about caterpillars in general than anyone else on the planet. Wagner’s “Caterpillars of Eastern North America,” published in 2005, runs to nearly five hundred pages. It relates the life histories of roughly that many species and is considered the definitive field guide on the subject. There are roughly sixty-five hundred species of mammals, nine thousand species of amphibians, and eleven thousand species of birds. But the planet’s real diversity lies mostly beneath our regard. The largest family of beetles, the Curculionidae, contains some sixty thousand described species; another beetle family comprises twenty thousand species. It is estimated that in one family of parasitic wasps, the Ichneumonidae, there are nearly a hundred thousand species, which is more than there are of vertebrates of all kinds.

An engineer in Wisconsin claims to have improved grief’s design. Aerodynamic, he says, showing off his sketches, barely grief at all! Applying physics like salve to a wound, he remembers what Torricelli said about vacuums, what Carnot said about absolute terror. He grabs a pencil and revises one more time. There’s money to be made in this, his father would assure, chopping chicken-necks through the afternoon. Flightless birds! The engineer pores over schematics, grimaces at draft after draft. His last sketch: confused. Joints unlabeled. A room inside a room inside a room.

J. Estanislao Lopez (2022)

In March 2020, the Internet Archive, a nonprofit created by the entrepreneur Brewster Kahle, launched a new feature called the National Emergency Library. Restrictions linked to the spread of COVID-19 had made it difficult or impossible for people to buy books or visit libraries in person, and so the Archive removed limits on the digital borrowing of the books in its database—of which there were more than three million, most of them in turn borrowed from physical libraries and scanned—and made them all publicly available, for free. The project was supported by a number of universities, researchers, and librarians. But some of the authors and publishers who owned the copyright to these books saw it not as a public service, but as theft.

In June 2020, Four publishers—Hachette, HarperCollins, John Wiley & Sons, and Penguin Random House—filed a lawsuit. The Internet Archive shut down the project, and went back to its previous policy of “Controlled Digital Lending,” which only allowed one person to borrow a free digital copy of a book at any given time. But this didn’t stop the lawsuit—because the publishers argued that any digital lending by the Archive constituted illegal infringement of the publishers’ copyright.

Last week, Judge John G. Koeltl, of the Southern District of New York, came down in favor of the publishers and dismissed every aspect of the Archive’s defense, including the claim that its lending program is protected by the “fair use” exception in copyright law. Koeltl wrote that the concept of fair use protects transformative versions of copyrighted works—a copy of a famous photo used in an artistic collage, for example—and that the Archive’s copies of books don’t qualify; the Archive made the case that its lending program  is transformative because the practice “facilitates new and expanding interactions between library books and the web,” the judge noted, but he ruled that just because the Archive might be “making an invaluable contribution to the progress of science and cultivation of the arts” did not make the use transformative.

On finalizing his acquisition of Twitter last October, one of the first things that Elon Musk did was announce that users would need to pay twenty dollars a month if they wanted to access premium “Twitter Blue” features. Twitter Blue launched in 2021, under Twitter’s previous management, at a price of five dollars per month; it offered subscribers the ability to edit tweets for thirty seconds after sending them, among other features including a bookmarking function and a tool for reading long Twitter threads. Musk suggested that his price hike would be worth it because Twitter Blue would also now give users a coveted blue checkmark showing that they had been verified. Musk said that those who already had blue checks would have ninety days to start paying for Twitter Blue before they lost their verified status. Some verified celebrities were not amused by this plan and said so, including on Twitter. “$20 a month to keep my blue check?” the author Stephen King tweeted. “If that gets instituted, I’m gone like Enron.”

A few days later, Musk lowered the cost of verification to the low low price of eight dollars a month. He argued that Twitter’s original verification system was elitist, since only some members of the media and celebrities had blue checks. “Twitter’s current lords & peasants system for who has or doesn’t have a blue checkmark is bullshit,” he wrote on November 1. “Power to the people! Blue for $8/month.” But, as with so much else Musk has touched, the rollout of the new feature quickly turned into a train wreck. Some users who were already verified showed their contempt for the new plan by changing their account details and pretending to be someone else. The comedian Sarah Silverman pretended to be Musk by copying his profile picture and display name, then tweeted satirical comments. (“I am a freedom of speech absolutist and I eat doody for breakfast every day.”) The actress Valerie Bertinelli also changed her profile name to Musk’s, then tweeted support for Democratic candidates in the 2022 midterms. (Musk had called on “independent-minded voters” to back Republicans.)

Musk responded on Twitter that any account engaging in impersonation without specifying that it was a parody would be permanently suspended, and that changing an account name would result in the “temporary loss” of the user’s checkmark. The train wreck wasn’t over, however. Twitter’s own official account announced that in order to prevent impersonation, it would offer a separate “official” badge that would be added to “government accounts, commercial companies, business partners, major media outlets, publishers and some public figures.” A few minutes later, Musk announced that he had killed the feature, although the new, white checkmarks that came with it remained attached to some accounts. Meanwhile, over the next few days, the impersonations continued: as Engadget noted, an account posing as Nintendo posted a picture of Mario with his middle finger raised, while an account claiming to be LeBron James said that he was looking to get traded. Most infamous, perhaps, was the time that a verified account claiming to belong to the pharmaceutical company Eli Lilly tweeted: “Insulin is free now.” The account of the real Eli Lilly apologized; its insulin was not in fact free now. The fake tweet and ensuing chaos erased around fifteen billion dollars from the company’s market cap.

Barnum Brown was marked for greatness from a young age. Born on a Kansas farm on February 12, 1873, the third child of Clara and William Brown went weeks without a name. Nearby Topeka was plastered with advertisements for P.T. Barnum’s traveling circus at this time, as were cities throughout the Midwest. The colorful posters still loomed large in 6-year-old Frank Brown’s mind when his baby brother arrived. As his parents argued about what to name their new son, Frank offered a suggestion: “Let’s call him Barnum.” Young Barnum’s life bore no resemblance to that of the enterprising circus showman, but he would live up to his name. He showed little interest in farming the family’s property and preferred combing the grounds around his home for fossils. His father ran a modest strip-mining operation on their coal-rich property, and the plows and scrapers unearthed ancient treasures. Corals and seashells littered the landscape. Barnum collected enough fossils to stuff every drawer in the house.

The true story of the president who couldn’t hear music

When Ulysses S. Grant was inaugurated for his first presidential term in 1869, thousands of people showed up to celebrate. It was one of the grandest and swankiest parties held in generations, and naturally included lots of music, mostly parade-marching tunes that set the tone of the event. Yet one person who did not enjoy the sound of the beat was the incoming president himself. There’s a famous line attributed to the acclaimed Civil War general: “I know of only two tunes: one of them is Yankee Doodle Dandy, and the other isn’t.” Underneath the joke was a real neurological condition that Grant had, although he never knew it. This disorder also would also afflict at least two other future presidents, Theodore Roosevelt and William H. Taft. It is known as “congenital amusia,” or an inability to hear music and understand it as — well — music. To those with the condition, music typically sounds cacophonous, like noise.

In 1832, Europe was in the throes of a cholera epidemic. A Scottish doctor named Thomas Latta knew cholera patients’ blood lacked water and salt, so he’d tried pumping a briny solution directly into the veins of an elderly patient. At first there was no response, but then the woman started to grow stronger. Nearly 140 years after Latta’s experiments, work on the disease would lead to one of the 20th century’s most consequential medical discoveries: oral rehydration solution (ORS). This cheap, simple solution of sugar, salts, and water mixed in the right proportions and delivered orally has saved the lives of more than 70 million, mostly children, since its introduction in the 1970s. It has helped slash the number of children under five dying of diarrhoeal diseases from around 4.8 million in 1980 to about 500,000 today. All of this from a drink that in its most basic form can be made by anyone with access to kitchen salt, sugar, and water.

Last time a president was arrested it was for going too fast in his horse-drawn buggy

The last time a US President was arrested, it involved a speeding horse and buggy, the thunder of hooves near the White House and a repeat offender who happened to be the president of the United States. Ulysses S. Grant, who had an eye for spirited horses and an apparent yen to test their mettle, was arrested in 1872 for speeding on a street in Washington, where he had been driving a two-horse carriage. It was the second time in two days that the policeman had stopped the president; the first time, the officer had issued him a warning. The Grant episode apparently wasn’t reported in the press at the time, but it came to light in 1908 when The Sunday Star newspaper in Washington published an interview with the then-retired officer who pulled the 18th president of the United States over.

It was March 1827 and Ludwig van Beethoven was dying. As he lay in bed, wracked with abdominal pain and jaundiced, grieving friends and acquaintances came to visit. And some asked a favor: Could they clip a lock of his hair for remembrance? The parade of mourners continued after Beethoven’s death at age 56, even after doctors performed a gruesome craniotomy, looking at the folds in Beethoven’s brain and removing his ear bones in a vain attempt to understand why the revered composer lost his hearing. Within three days of Beethoven’s death, not a single strand of hair was left on his head. Ever since, a cottage industry has aimed to understand Beethoven’s illnesses and the cause of his death. Now, an analysis of strands of his hair has upended long held beliefs about his health. The report provides an explanation for his debilitating ailments and even his death, while raising new questions about his origins and hinting at a dark family secret.

What were Neanderthals really like—and why did they go extinct?

When limestone quarry workers in Germany’s Neander Valley discoveredfossilized bones in 1856, they thought they’d uncovered the remains of a bear. In fact, they’d stumbled upon something that would change history: evidence of an extinct species of ancient human predecessors who walked the Earth between at least 400,000 and 40,000 years ago. Researchers soon realized that they had already encountered these human relatives in earlier fossils that had been found, and misidentified, throughout the early 19th century. The discovery galvanized scientists eager to explore new theories of evolution, sparking a worldwide fossil hunt and tantalizing the public with the possibility of a mysterious sister species that once dominated Europe. Now known as Neanderthals—so named by geologist William King—Homo neanderthalensis are humans’ closest known relatives.

In 1747, the young poet Johann Wilhelm Ludwig Gleim was sitting in his study in the small German town of Halberstadt, surrounded by stacks of letters from his friends and associates, and had an epiphany. He realized that despite having corresponded with so many people, he had never actually met most of them in person. And this got him thinking: what if there was a way to visualize all the people he had formed relationships with through letter writing? And thus, the poet’s Temple of Friendship was born. Gleim set out to collect painted portraits of all his friends and relatives, creating an extensive personal portrait gallery that soon filled all the walls of his apartment. He referred to this portrait gallery as his Tempel der Freundschaft (“Temple of Friendship”). He carefully thought about the arrangement of his portrait gallery: his own portrait was always at the center of the gallery, while other portraits were positioned around it.

Jean Denis and the “Transfusion Affair”

Beginning in the spring of 1667, public opinion in Paris was rocked by a remarkable affair involving domesticated animals: the first practical experiments to transfuse animal blood into humans for therapeutic purposes. The experiments that came to be known as the “Transfusion Affair” were shrouded in the competing claims of a highly public controversy in which consensus and truth, alongside the animal subjects themselves, were the first victims. “There was never anything that divided opinion as much as we presently witness with the transfusions”, wrote the Parisian lawyer at Parlement, Louis de Basril, late in the affair, in February 1668. “It is a topic of the salons, an amusement at the court, the subject of philosophical dissertations; and doctors talk incessantly about it in all their consultations.” At the center of the controversy was the young Montpellier physician and “most able Cartesian philosopher” Jean Denis, who experimented with animal blood to cure sickness, especially madness, and to prolong life.
