Yuichi Hirose has a dream—a dream that someday everyone will have access to a machine capable of knitting furniture.

This machine wouldn’t just knit the furniture’s exterior fabric, but would use knitting to fashion solid three-dimensional chairs, tables and other objects. Tired of that love seat? Just unravel it and reuse the yarn to knit yourself an ottoman. This new fabrication technique—first envisioned by Hirose, a robotics Ph.D. student in Carnegie Mellon University’s School of Computer Science—is called solid knitting. The idea captured his imagination more than a decade ago. And now, working with a research team headed by James McCann, an associate professor in the Robotics Institute, he’s made it a reality.

“My dream is to have these solid knitting machines everywhere in the world,” Hirose said.

While he was still building the machine, Hirose saw a report on the internet about a software project by McCann that made it easier to reprogram commercial knitting machines. This method provided a practical way to use the machines to make customized 3D knitted pieces. These were hollow shapes, such as bunny rabbits that could be stuffed, not solid knitted pieces, but Hirose and McCann began talking about a possible collaboration.

Simply put, downtowns matter less and less. In Austin and elsewhere, we are witnessing an epochal shift away from the highly concentrated urban center first described by Jean Gottmann in 1983 as the “transactional city.” Gottman spoke of a future dominated by massive high-rise office buildings filled with professionals who commuted largely from the periphery. Yet in reality, jobs have been dispersing throughout metro areas since the 1950s. Bumsoo Lee and Peter Gordon showed that downtowns for cities with the largest populations had dropped to 7 percent of metropolitan employment by 2000, while 78 percent of jobs were located in dispersed areas. Office occupancy and construction of new space have both seen a net decline since the turn of the century. The same goes for businesses, as investment in corporate real estate moves away from dense urban areas.

Remote work, rising before the pandemic but greatly expanded since, allows professionals to work ever further away from their place of employment. According to a 2023 paper at Stanford, work-from-home constituted about 7 percent of workdays before the pandemic and over 60 percent at its peak.

Phil Christman in The Hedgehog Review:

Every so often someone writes an essay with a title like “Against Travel,” “The Case for Staying on One’s Couch,” or “Germans in Sweatpants: Why Going Places Was a Mistake.” Such pieces usually go viral, since they appeal to the two itches few readers seem able to resist scratching—the itch to be agreed with and the itch to be mad at a stranger. I always root for the writers of these pieces. I want them to win the impossible fight they’ve picked.

Why should I feel this way about travel? What has it ever done to me? Travel is one of those things one generally doesn’t attack in polite company, the world of letters excepted. Its wholesomeness is assumed. It broadens the mind. It makes us empathetic and, by rewarding our curiosity, encourages it to develop further. It teaches people the just-right amount of relativism —the amount that makes them easygoing in company, perhaps usefully pliable in exigencies, but not nihilistic. Only a fool or a misanthrope would criticize travel.

Raiany Romanni in Bioethics Today:

If there’s one phrase the June 2024 U.S. presidential debate may entirely eliminate from the English vocabulary it’s that age is a meaningless number. Often attributed to boxer Muhammad Ali, who grudgingly retired at age 39, this centuries-old idea has had far-reaching consequences in global politics, as life expectancy more than doubled since the start of the 20th century, and presidents’ ages shifted upwards. We say “age is what we make of it” to ourselves and to policymakers, and think it’s a harmless way to dignify the aged. But how true is it? And if it isn’t true, why would we lie?

For centuries, we have confused our narrative of what aging should be with what its ruthless biology is. Yet pretending that biological age does not matter is at best myopic, and at worst, it’s a dangerous story to our governments, families, and economies. In just 11 years — between 2018 and 2029 — U.S. spending on Social Security and Medicare will more than double, from $1.3 trillion to $2.7 trillion per year. As we age, our odds of getting sick and dying by basically anything go up exponentially.

In 2016, a historically unprecedented incident took place. And yet, barely anyone even noticed. Even years later, we’ve failed to acknowledge it or to have begun the process of understanding it. Because we still can’t even see it.

And that’s because this incident involved a woman. And she was asking for it.

The woman was Hillary Clinton. What she was asking for was votes. And what she got was the single biggest outpouring of misogyny in human history.

We can now say that. Although no one ever does. But this was an unprecedented previously unimaginable event. Because 2016 was when the world’s first global instant mass communication technology – social media – crashed up against the most ancient of prejudices – misogyny.

And the result was an earthquake: Donald Trump.

When Tintin is captured by an ancient Inca tribe in his fourteenth adventure, Prisoners of the Sun, he finds an article on his cell floor that forecasts a coming solar eclipse. This will prove to be significant since he, Captain Haddock, and Professor Calculus are to be burned at the stake. Tintin manages to see to it that the execution is staged at the right moment. When the Inca Prince of the Sun orders the pyre to be lit, Tintin invokes the Sun God: “O God of the Sun, sublime Pachacamac, display thy power, I implore thee! … If this sacrifice is not thy will, hide thy shining face from us!” In this patronizing Occidental fable of mathematical calculation triumphing over traditional belief, the weather god gives way to the scientist, whose knowledge gives Tintin the power to produce an apparent miracle.

The scientist who made such exact prognostications possible was the German astronomer Johannes Kepler. In 1600, he was hired as an assistant by the Danish astronomer Tycho Brahe and was given the painstaking task of analyzing observations of Mars made by Tycho and compiling them into a new set of astronomical tables.

From Edge:

JOHN TOOBY (July 26, 1952-November 9, 2023) was the founder of the field of Evolutionary Psychology, co-director (with his wife, Leda Cosmides) of the Center for Evolutionary Psychology, and professor of anthropology at UC Santa Barbara. He received his PhD in biological anthropology from Harvard University in 1989 and was professor of anthropology at the University of California, Santa Barbara. Tooby and Cosmides also co-founded and co-directed the UCSB Center for Evolutionary Psychology and jointly received the 2020 Jean Nicod Prize.

Tooby was known for his work with his collaborators to integrate cognitive science, cultural anthropology, evolutionary biology, paleoanthropology, cognitive neuroscience, and hunter-gatherer studies to create the new field of evolutionary psychology, toward the goal of the progressive mapping of the universal evolved cognitive and neural architecture that constitutes human nature and provides the basis of the learning mechanisms responsible for culture. This involves using knowledge of specific adaptive problems our hunter-gatherer ancestors encountered to experimentally map the design of the cognitive and emotional mechanisms that evolved among our hominid ancestors to solve them.

Kamal Nahas in The Scientist:

Cancers typically arise when cells accumulate mutations in their DNA that prevent them from keeping cell division in check.¹ However, for some tumor types, researchers have struggled to find mutations, leading scientists to question their causes.² Now, in a study published in Nature, researchers found that short-lived epigenetic changes can permanently alter gene expression and trigger cancer.³ While most cancers develop following mutations, their findings suggest that a few tumor types might deviate from this rule. For years, Giacomo Cavalli, a geneticist at the French National Centre for Scientific Research, and his colleagues have studied the role that epigenetic factors called Polycomb proteins play in cancer.⁴ These proteins form complexes that wind up chromatin and switch off genes that promote cell division. The team previously found that mutations in Polycomb factors cause chromatin unraveling, which cascades into cell proliferation and cancer initation.⁵ They wondered whether they could achieve the same effect by temporarily switching Polycomb genes off.

To test their hypothesis, they turned to the fruit fly, Drosophila melanogaster; the species has only one copy of each gene involved in the Polycomb machinery, making it easier to disrupt the system. Polycomb proteins play key roles during development by influencing the timing of cell differentiation. Cavalli and his team studied the impact of losing this epigenetic control on early, larval structures called imaginal discs. Using a temperature-sensitive RNA interference system, they exposed the discs to warmer temperatures for 24 hours, which temporarily turned off the Polycomb genes for two days.  “They very nicely showed that with this transitory system they could switch off this development gene briefly, switch it back on, and that was enough to trigger tumorigenesis,” said Douglas Hanahan, a cancer biologist at the Swiss Federal Institute of Technology Lausanne who was not involved with the work.

A mountain of historical studies testifies to enduring interest in the American Civil War, a conflict still politically relevant in a nation riven over how to remember it. Those doubting that there is anything fresh to say about the bloodiest event in the republic’s history should read Pulitzer Prize winner Alan Taylor’s brilliant, panoramic account of the conflict. Applying a wide continental lens, he explores this crux of United States history and how it shook neighbouring Mexico and Canada. In all three settings, liberals and social and political conservatives were involved in parallel struggles to build a modern nation. After a French invasion, the creation of a short-lived monarchy and a devastating civil war, the Liberal Party leader Benito Juárez returned to power in Mexico. Fearing the growing power and rapacity of the United States, meanwhile, Canadians navigated internal divisions to create a continental confederation. And in the United States, the pulsing heart and geographical centre of events, Abraham Lincoln’s Union forces subdued the reactionary and rebel slave power to achieve emancipation and the constitutional basis for a more liberal and democratic nation.

Taylor’s lively account of the conflict in the United States follows mostly familiar lines. Insisting that enslavement was a positive good for the people of African origin and that slavery had to grow to survive, Southerners demanded the right to settle the vast western territories beyond the Mississippi.

The day I met Daniel Kahneman, he had asked me to join him for lunch at the Bowery Road restaurant in Lower Manhattan. Danny proposed this venue because it has comfortable booths and ‘is mostly deserted’. I arrived 15 minutes early, palms sweaty with the anticipation of meeting the world’s most famous psychologist. He had agreed to discuss making a film of his life’s work. I’d been preparing my pitch all week, and had brought a stack of notes with me to the restaurant. Half an hour passed, and he hadn’t arrived. I sent his secretary an email. Another 45 minutes ticked by before I abandoned hope. I headed back uptown, expectations shot.

As I walked through the apartment door, my phone buzzed. Danny’s name shone on the caller ID. ‘I’m terribly sorry,’ he said as soon as I answered. ‘Please tell me where to find you.’ I told him I could head back downtown in a few minutes. Before hanging up, he apologised once more: ‘I’m very sorry. This doesn’t usually happen. But I sometimes make mistakes.’

The IMO is considered the world’s most prestigious competition for young mathematicians. Correctly answering its test questions requires mathematical ability that AI systems typically lack.

In January, Google DeepMind demonstrated AlphaGeometry, an AI system that could answer some IMO geometry questions as well as humans. However, this was not from a live competition, and it couldn’t answer questions from other mathematical disciplines, such as number theory, algebra and combinatorics, which is necessary to win an IMO medal.

Google DeepMind has now released a new AI, called AlphaProof, which can solve a wider range of mathematical problems, and an improved version of AlphaGeometry, which can solve more geometry questions.

Francis Fukuyama at Persuasion:

In his acceptance speech for the vice presidency at the Republican National Convention, JD Vance stated that “one of the things that you hear people say sometimes is that America is an idea.” But, Vance asserted, the country was not just a “set of principles … but a homeland.” He went on to illustrate this by referring to his family’s cemetery where he hoped seven generations would be buried in a plot in eastern Kentucky. He said the country welcomed newcomers like his wife’s family from India, but “when we allow newcomers into our American family, we allow them on our terms.”

Taken at face value, this should not be particularly controversial. American identity has always been based on ideas like liberty and equality, making it what is sometimes labeled a “creedal nation.” But it also is a nation of shared memory and experience. And it is doubtless true that immigrants to the United States need to accept certain basic conditions for being an American, as required by their taking the oath of naturalization during the citizenship ceremony.

The real question is what Vance means by the phrase “on our terms” as a condition for Americanness.

Computer chips are a hot commodity. Nvidia is now one of the most valuable companies in the world, and the Taiwanese manufacturer of Nvidia’s chips, TSMC, has been called a geopolitical force. It should come as no surprise, then, that a growing number of hardware startups and established companies are looking to take a jewel or two from the crown.

Of these, Cerebras is one of the weirdest. The company makes computer chips the size of tortillas bristling with just under a million processors, each linked to its own local memory. The processors are small but lightning quick as they don’t shuttle information to and from shared memory located far away. And the connections between processors—which in most supercomputers require linking separate chips across room-sized machines—are quick too.

This means the chips are stellar for specific tasks. Recent preprint studies in two of these—one simulating molecules and the other training and running large language models—show the wafer-scale advantage can be formidable. The chips outperformed Frontier, the world’s top supercomputer, in the former. They also showed a stripped down AI model could use a third of the usual energy without sacrificing performance.

Like many creative ventures in cities that are in thrall to the real estate industry, the Poetry Project was itself a miracle, a space emerging out of the chaos and communal energy of a small circle. In 1966, a set of poets who had been gathering at Le Metro and Les Deux Mégots (pun and homage intentional) went through some internecine squabbles and found themselves in need of a new spot for readings. St. Mark’s Church in-the-Bowery, on East 10th Street, was that place. Consecrated in 1799, it’s the second-oldest church building in Manhattan, located on New York’s oldest site of “continuous religious practice.” By the 1960s, it was home to something else, too: Theater Genesis had taken root there, jazz performances were happening during the summer, and poetry readings were common. The church’s reverend, Michael Allen, was active in protests against the war in Vietnam and was generally open to rogue events that might bring locals together.

As reported in Daniel Kane’s All Poets Welcome, the Poetry Project obtained its initial financial support in the form of an unlikely grant. A man named Israel Garver, a federal employee in the Department of Health, Education, and Welfare’s Office of Juvenile Delinquency and Development, was in charge of allocating funds that needed to be disbursed by the end of the fiscal year.
