Clay Shirky writes: I remember the moment I knew my approach to student use of artificial intelligence was not working. Early in a meeting at N.Y.U.’s Abu Dhabi campus last fall, a philosophy professor, arms crossed over his chest, told me he’d tried one of the strategies my office had suggested — talking with his students about the ways A.I. could interfere with their learning — and it hadn’t worked. His students had listened politely, then several of them had…
Wired reports: Marine biologist and conservationist David Shiffman was an early power user and evangelist for science engagement on the social media platform formerly known as Twitter. Over the years, he trained more than 2,000 early career scientists on how to best use the platform for professional goals: networking with colleagues, sharing new scientific papers, and communicating with interested members of the public. But when Elon Musk bought Twitter in 2022, renaming it X, changes to both the platform’s algorithm…
Jake Buehler writes: Over the last half-billion years, squid, octopuses and their kin have evolved much like a fireworks display, with long, anticipatory pauses interspersed with intense, explosive changes. The many-armed diversity of cephalopods is the result of the evolutionary rubber hitting the road right after lineages split into new species, and precious little of their evolution has been the slow accumulation of gradual change. They aren’t alone. Sudden accelerations spring from the crooks of branches in evolutionary trees, across…
The Independent reports: The National Guard, called in to deal with a “crime emergency” in DC declared by Donald Trump, have been spotted picking up trash. Troops were seen donning yellow marigolds and orange high-visibility vests over their camouflage gear Tuesday as they picked up litter in Lafayette Park, just outside the White House. According to officials, the military was deployed as part of a “beautification and restoration mission” in Lafayette Square, the National Mall, and the Tidal Basin. At…
The New York Times reports: Federal prosecutors on Tuesday were unable to secure a felony assault indictment against a man who threw a sandwich at a federal agent on the streets of Washington this month, according to two people familiar with the matter. The remarkable failure by the U.S. attorney’s office in Washington was the second time in recent days that it was unable to persuade grand jurors to bring an indictment in a felony assault case against a federal…
Quinnipiac University Poll reports: In the wake of President Donald Trump’s decision to send National Guard troops to Washington D.C. in an effort to reduce crime, voters 56 – 41 percent oppose the move, according to a Quinnipiac (KWIN-uh-pea-ack) University national poll of registered voters released today. There are wide partisan and gender differences. Republicans (86 – 12 percent) support the president’s decision to deploy the National Guard to the nation’s capital to reduce crime, while Democrats (93 – 5…
Victoria Guida writes: The Federal Reserve is not a place that panics. My experience of the central bank and its staff is that they try to think as many steps ahead as possible. Just as Fed policymakers weigh the balance of risks to the economy, and the many potential scenarios that may unfold, they similarly weigh the balance of political risks to their mandate and autonomy. It’s an institution made up of regular people, of course — people who feel…
Anagha Nair writes: Earphones plugged in, a cigarette dangling from his hand, Mohammed al-Mohammed was waiting for a train at a station in Hamburg, Germany, when he was enveloped by screams of horror. Amid the chaos of people fleeing, he glimpsed a flash of metal out of the corner of his eye. Turning, he saw a lady clutching a raised knife, pointed toward him. Mohammed’s reflexes kicked in, and he pushed the lady away. As another man tackled her and…
John Cassidy writes: In a 1987 article in the Times Book Review, Robert Solow, a Nobel-winning economist at M.I.T., commented, “You can see the computer age everywhere but in the productivity statistics.” Despite massive increases in computing power and the rising popularity of personal computers, government figures showed that over-all output per worker, a key determinant of wages and living standards, had stagnated for more than a decade. The “productivity paradox,” as it came to be known, persisted into the…
Science reports: Life today depends on proteins, cellular workhorses that do everything from flex muscles to ferry oxygen. And proteins, in turn, depend on RNA, which carries the recipes for making them and also helps with their assembly. In modern cells, large protein-based enzymes help connect RNA snippets to amino acids, the building blocks of proteins. Then, the RNA- and protein-based cellular machine called the ribosome stitches the amino acids together into a protein chain, reading the correct sequence from…
Politico reports: Europe’s central bankers were cautiously critical Tuesday of U.S. President Donald Trump’s efforts to oust a top Federal Reserve official. They expressed unease at the potential spillover effects from a growing political threat to the independence of the world’s most important central bank. Trump invoked sweeping executive powers to unseat Federal Reserve Governor Lisa Cook in an unprecedented challenge to the legally enshrined independence of the Fed on Monday, after housing chief William Pulte accused her of mortgage…
Fortune reports: After saying that the U.S. is on the precipice of a recession earlier this month, Moody’s Analytics chief economist Mark Zandi continued to add more granularity to his warning. In social media posts on Sunday, he said his assessments of various datasets indicate that states accounting for nearly a third of U.S. GDP are already in a recession or at high risk of slipping into one. Another third is treading water, while the last third is still expanding….
The New York Times reports: The Trump administration is aggressively stoking tensions with Venezuela and its president, Nicolás Maduro, and appears to be creating conditions that could lead to a military confrontation. A major buildup of U.S. naval forces is underway outside Venezuela’s waters as the administration has stepped up belligerent rhetoric about fighting drug cartels and labeled Mr. Maduro a terrorist-cartel leader. All that raises the question of whether the end goal is just to counter drug-smuggling boats, or…
Politico reports: A federal judge has forcefully rejected a highly unusual lawsuit the Trump administration filed against 15 other judges whom the Justice Department accused of hindering the president’s mass deportation agenda. In tossing out the lawsuit, U.S. District Judge Thomas Cullen — an appointee of Donald Trump — lamented what he described as the White House’s months-long “smear” of the federal judiciary. Cullen wrote in a 39-page decision Tuesday that the lawsuit was unprecedented, defective and the wrong way…
