Many dentists still prescribe opioid painkillers to patients, study says

Though most U.S. dentists say non-opioid painkillers effectively manage dental pain, nearly half still prescribe potentially addictive opioid painkillers, a new survey reveals.

In all, 84% of the 269 respondents said NSAID-acetaminophen combos are as effective as opioids or even more so, but 43% also said they regularly prescribe opioid medications.

The findings were published Thursday in the Journal of the American Dental Association.

"These results suggest that dentists are familiar with the evidence about the effectiveness of NSAID-acetaminophen medications, but their self-reported prescribing patterns demonstrate a disconnect," first author Matthew Heron said in a Georgetown news release.

Heron conducted the study as an undergraduate at Georgetown University's School of Nursing and Health Studies in Washington, D.C.

Previous studies have found that dentists represent 8.6% of opioid prescribers in the United States, and are the biggest prescribers of opioids to patients 18 and younger.

"We know that the first exposure to opioids for many people occurs in their teens and early 20s following common dental procedures like third molar extractions," said study co-author Nkechi Nwokorie, who also conducted the work as a Georgetown undergrad.

"This is a particularly vulnerable population for misuse," Nwokorie said.

Dr. Adriane Fugh-Berman is director of PharmedOut, a Georgetown project that was involved in the study.

"This underscores the need for more education about the harms of opioids and the need for national guidelines to align clinical practice with current evidence," she said. Fugh-Berman is also a professor in the departments of pharmacology, physiology and family medicine at Georgetown University Medical Center.

Dinosaurs may have lived in 'social' herds 193 million years ago, study finds

THE IDEA OF DINOSAUR INDIVIDUALISM WAS THE RESULT OF SPENCERIAN BOURGEOIS SCIENCE
OF THE 19TH & 20TH CENTURIES

Oct. 21 (UPI) -- Prehistoric creatures lived in social herds 193 million years ago, about 40 million years earlier than previously thought, an analysis published Thursday by Scientific Reports found.

The results, based on dating of sediments found among a discovery of fossils, suggest the dinosaur herd dates back to the early Jurassic period, the earliest evidence of social herding among dinosaurs, the researchers said.

Living in herds may have given this particular species of dinosaur, the Mussaurus patagonicus, an evolutionary advantage, according to the researchers.

Early dinosaurs originated in the late Triassic period, shortly before an extinction event wiped out many other animals, but the Mussaurus patagonicus survived and eventually dominated the terrestrial ecosystem in the early Jurassic period.

"We've now observed and documented this earliest social behavior in dinosaurs," co-author Jahandar Ramezani said in a press release.

"This raises the question now of whether living in a herd may have had a major role in dinosaurs' early evolutionary success and gives us some clues to how dinosaurs evolved," said Ramezani, a research scientist at the Massachusetts Institute of Technology in Cambridge.

The findings are based on an analysis of 100 exceptionally well-preserved early dinosaur eggs and partial skeletons of 80 juvenile and adult dinosaurs from a rich fossil bed in southern Patagonia, the researchers said.

Using X-ray imaging, they were able to examine the eggs' contents without breaking them apart.

Using the preserved embryos within the eggs, the researchers were able to confirm that the fossils were all members of Mussaurus patagonicus, a plant-eating dinosaur that lived in the early Jurassic period.

The Mussaurus patagonicus is classified as a sauropodomorph, a predecessor of the massive, long-necked sauropods that later roamed the Earth.

The researchers observed that the fossils were grouped by age, with dinosaur eggs and hatchlings found in one area and skeletons of juveniles in a nearby location, they said.

Meanwhile, remains of adult dinosaurs were found alone or in pairs throughout the field site.

This "age segregation" is a sign of a complex, herd-like social structure, suggesting the dinosaurs worked as a community, laying their eggs in a common nesting ground, while juveniles congregated in "schools," and adults roamed and foraged for the herd, the researchers said.

"This may mean that the young were not following their parents in a small family structure," Ramezani said.

"There's a larger community structure, where adults shared and took part in raising the whole community," he said.

The fossils identified so far were found in three sedimentary layers spaced close together, suggesting that the region may have been a common breeding ground where the dinosaurs returned regularly, perhaps to take advantage of favorable seasonal conditions.

Among the fossils they uncovered, the team discovered a group of 11 articulated juvenile skeletons, intertwined and overlapping each other, as if they had been thrown together.

However, given the remarkably preserved nature of the entire collection, it appears this particular herd of Mussaurus died at roughly the same time, perhaps in a flash flood, according to the researchers.

The sediments among the fossils included volcanic ash, which may contain zircon as well as uranium and lead, they said.

Based on uranium's half-life, or the time it takes for half of the element to decay into lead, the researchers were able to calculate the age of the zircon and the ash in which it was found.

They successfully identified zircons in two ash samples, all of which were dated to around 193 million years ago.

Taken together, the team's results show that Mussaurus and possibly other dinosaurs evolved to live in complex social herds as early as 193 million years ago, around the dawn of the Jurassic period.

Scientists suspect that two other types of early dinosaurs, Massospondylus from South Africa and Lufengosaurus from China, also lived in herds around the same time, although the dating for these dinosaurs has been less precise, according to Ramezani and his colleagues.

If multiple separate lines of dinosaurs lived in herds, the social behavior may have evolved earlier, perhaps as far back as their common ancestor, in the late Triassic period, the researchers said.

"Now we know herding was going on 193 million years ago," Ramezani said.

"This is the earliest confirmed evidence of gregarious behavior in dinosaurs. But paleontological understanding says, if you find social behavior in this type of dinosaur at this time, it must have originated earlier," he said.

Curators squeezed out by high dino bones price tag
'Big John' was discovered in South Dakota in 2014

With an estimated price tag of up to 1.5 million euros ($1.7 million), Duranthon, who directs the Toulouse Museum of Natural History, told AFP the skeleton would cost 20 to 25 years of his acquisitions budget.

"We can't compete," he said.

The triceratops is among the most distinctive of dinosaurs due to the three horns on its head -- one at the nose and two on the forehead -- that give the dinosaur its Latin name.

"Big John" is the largest known surviving example, 66 million years old and with a skeleton some eight metres long.

It was discovered in South Dakota in 2014 and flown to Italy where it was assembled by specialists.

It is only the latest dinosaur to be sold by the Drouot auction house which, according to its website, handled an allosaurus and a diplodocus each worth 1.4 million euros in 2018.

Last year, they sold a second allosaurus for three million.

That these and other skeletons could adorn the private mansions of the ultra-wealthy rather than museum halls is a common source of frustration.

For Steve Brusatte, a consultant on the forthcoming "Jurassic World" movie, "dinosaur fossils belong in museums".


The author of "The Rise and Fall of the Dinosaurs" remembers being a teenager and seeing the fossil that would inspire him to go into palaeontology.

"The T. rex skeleton Sue was put on display at the Field Museum in Chicago," Brusatte told AFP.

"It awed me and, standing under it, it gave me a new perspective on the ancient world."
Lost to history?

If very rare artefacts go directly into private collections, there could be a loss for the scientific community, said Annelise Folie, curator of palaeontology collections at Belgium's Royal Institute of Natural Sciences.

"If it's a new species... we may never even be aware that it existed on Earth," she told AFP.

It is also impossible to say without investigation "whether a skeleton contains new information or not," said palaeontologist Nour-Eddine Jalil, of Paris' Museum of Natural History.

Although, the lure of selling fossils could motivate new archaeological expeditions.

In the case of Big John, the sale is "not a big deal because we already have plenty of triceratops," palaeontologist Pascal Godefroit of the Belgian Royal Institute of Natural Sciences told AFP.

Scientists had also been able to analyse the bones before the auction.

He said that while scientists can't force buyers to let them analyse specimens, the two sides are sometimes able to "work together intelligently".

But he said there are problems with many of the specimens put up for sale.

"It happens too often that you have interesting pieces but they're poorly identified," he said.

"Or have been made useless by efforts to make them more complete like filling them in with plastic."

Back in 1997, Sue the T. rex that sparked the imagination of the young Brusatte was also put up for auction.

Chicago's Field Museum was able to raise over $8 million to purchase it.

"But it could easily have gone the other way," said Brusatte.

"A single wealthy person could have bought it, brought it home and it would never have been put on display for the public, to inspire me and countless other children."

The 67-million-year-old "Sue" was discovered in 1990 on an Indian reservation in South Dakota by American palaeontologist Sue Hendrickson and was named after its finder.

The sale of "Big John" comes amid continued enthusiasm for dinosaur skeletons, with a 67-million-year-old T. rex skeleton smashing records when it was sold in New York for $31.8 million just over a year ago.

The triceratops has an export licence, and Alexandre Giquello of the Giquello auction house said in September that there were a dozen possible buyers.

Dinosaur sales can be unpredictable however: in 2020, several specimens offered in Paris did not find takers after minimum prices were not reached.

'Big John,' world's largest triceratops, sells for $7.7M

By Daniel Uria & Clyde Hughes

Oct. 21 (UPI) -- "Big John," the world's largest Triceratops fossil ever found, sold for $7.7 million Thursday at the Hotel Drouot auction house in Paris, setting a new European record.

The 66-million-year-old skeleton was first discovered in South Dakota by geologist Walter W. Stein Bill in 2014.

The name of the buyer, believed to be a U.S. collector, was not revealed.

The skeleton, which is about 60% complete, measures 26 feet long and had been expected to sell for between $1.4 million and $1.8 million, according to the Hotel Drouot.

Big John's skull alone, which is 75% complete, measures 6.6 feet wide, and his two largest horns each are nearly 4 feet long and 1 foot wide at the base.

The auction house says that a laceration on Big John's collarbone is evidence of a fight with a smaller triceratops.

"These violent combats took place during the lifetime of these animals, probably for reasons of territorial defense or courtship of a mate," Hotel Drouot said in a statement.

The triceratopses, which means "three-horned face," were herbivorous chasmosaurine ceratopsid dinosaurs that emerged during the late Maastrichtian stage of the Late Cretaceous period, close to 70 million years ago in what's now North America.

"Big John lived in Laramidia, an island continent stretching from present-day Alaska to Mexico. He died in an ancient flood plain -- the current Hell Creek geological formation [in South Dakota] -- allowing the conservation of his skeleton in mud, a sediment devoid of any biological activity."

In 2020, the bones were reassembled at the Zoic workshop in Italy under the supervision of paleontologist Iacopo Briano, who said the skeleton was 5% to 10% larger than that of any other triceratops previously discovered.

"It's a masterpiece," Briano said, according to The Guardian. "There are quite a few triceratops skulls around the world, but very few of them [are] almost complete."

A year ago, a 67 million-year-old Tyrannosaurus rex skeleton sold at auction for a record-breaking $31.8 million to become the most expensive fossil of all time.

Auctioneer Alexandre Giquello said Big John's immense skeleton would likely only pique the interest of about a dozen collectors throughout the world.

"There are ... people who are passionate about science and paleontology," Giquello said, according to The Guardian. "They are often quite young, coming from new technologies; they are in fact the Jurassic Park generation: they have seen the movies and have been immersed in this Hollywood mythology."

A crusade to end grading in high schools


Thomas Toch and Alina Tugend, 
Special To The Washington Post
Wed, October 20, 2021, 

Scott Looney, the head of the Hawken School near Cleveland and a leader in private education, had become disenchanted. The majority of American high schools, even the best money could buy, he believed, were delivering a misguided education. They treated students as passive receptacles and downplayed the importance of attributes such as collaboration and the many types of learning taking place outside classrooms. They reduced the high school experience of students with college aspirations to a formulaic pursuit of success in a narrow set of advanced courses that blocked many from exploring their passions.

Looney wanted to create a new secondary-school model, not just at Hawken and other privileged private schools, but also for the public school system that educated the vast majority of the nation's students. "The industrial production model of putting kids on an assembly line when they're 4 and moving them through at the same pace, asking them to do functionally the same work, is toxic," he told us at his Hawken office in May.

He envisioned schools where students learned math, history and science not as isolated subjects in classroom-bound courses but while working together to address real-world issues like soil conservation, homelessness and illegal immigration. Such learning would make schooling more meaningful for students and thus more engaging, Looney believed. It would let students demonstrate more talents to colleges, holding out the prospect of a wider, more diverse range of students entering higher education's top ranks.

The existing high school transcript, however, with its simple summary of courses and grades, wouldn't do justice to the interdisciplinary, project-based learning he wanted. It wouldn't capture students' creativity, persistence and other qualities. Looney needed a radically different way to portray students' high school experiences, one that replaced grades with a richer picture. But he didn't know what it was.

Neil Mehta changed that. Mehta was a Hawken parent and faculty member at the Cleveland Clinic Lerner College of Medicine in 2013 when he attended one of Looney's early presentations on his frustrations with high school education. Looney included grades among schooling's "sacred cows" that should be abandoned, proposing instead that students be awarded credits for achieving a school's standards on a range of knowledge, skills and learning traits.

After the presentation, Mehta mentioned to Looney that the Lerner medical school didn't give grades and measured its students' grasp of patient care, health-care systems and other topics by evaluating essays and supporting evidence gathered in electronic portfolios. "We're already doing what you're talking about," he told Looney. Looney met with Mehta, studied the Lerner model, visited its campus and was convinced he could track on a single digital platform the knowledge and skills students acquired during high school, without grades - what he would go on to call a mastery transcript. "I thought, hell, if they could do it at a medical school, I should be able to do it in high schools, where no one dies if you get it wrong."

Today, 275 private high schools and 125 public schools are part of the nonprofit Mastery Transcript Consortium (MTC). They are in various stages of designing and launching the transcript - and working to make Looney's radical vision a reality. Started in 2017, the organization is expanding rapidly.

The head of the Cleveland public school system recently joined the consortium's board of directors, and the consortium is in discussions with state and education officials in North Dakota, Vermont, Utah and elsewhere to bring the transcript to hundreds more public high schools. And after a pilot year, the consortium officially introduced the new transcript last fall, with 250 students in 14 of the member schools applying to more than 200 colleges and universities with the transcript - and earning admission to 170 schools as different as Middlebury College, MIT and the University of Oklahoma.

And yet, despite its early victories, Looney's crusade for a fundamentally different way of capturing students' high school experience has also drawn skeptics. They say that the mastery transcript is a bridge too far for already overburdened schools and college admission offices, and that abandoning grades would hurt disadvantaged students' college prospects.

Indeed, the trajectory thus far of the mastery transcript illuminates how hard it is both to change entrenched educational practices and to level the educational playing field for students from communities with fewer resources. It remains possible that the concept will turn out to be merely an idealistic and flawed pursuit from a passionate educator. Then again, maybe the mastery transcript is, in fact, the harbinger Looney wants it to be - the start of an evolution that expands what learning is, where it happens and how it's measured.

Looney, 57, was an unlikely revolutionary. He grew up in a working-class Chicago suburb, the son of a police officer and a customer service rep for a manufacturing company; he was born when his parents were teenagers. He went to desultory public schools, worked as a drugstore stock clerk at night, and was the first in his family to finish college, DePauw University in Indiana, where he showed up in a black Rush T-shirt. He graduated with a degree in psychology and went to work for schools that were a world apart from those he encountered growing up.

Looney parlayed a DePauw connection into a low-level admissions job at the private Phillips Academy in Andover, Mass., a quintessential New England boarding school serving the wealthy and well-connected since 1778. Next, as an admissions director at Lake Forest Academy, he catered to Chicago elites. During a decade in admissions and administration at Cranbrook Schools in Bloomfield Hills, Mich., he educated auto-industry scions.



Then, in 2006, he was named head of Hawken, a school founded in 1915, when Cleveland was a leading industrial center. Before long, Looney ascended to the executive committee of the National Association of Independent Schools, the professional organization of the private school world. For years, he ran a respected three-day summer retreat for private-school admissions officers in Kennebunkport, Maine.

But if many private school leaders hewed to the status quo, Looney was different. In 2011 he brought Doris Korda, a Bell Laboratories engineer and software entrepreneur turned high school math teacher, to Hawken to revamp the school's instruction. Later, she would help Looney launch a new Hawken high school to serve as a laboratory for his education ideas. It would be a school based entirely on "real world" learning, without traditional teaching and grades.

Looney and Korda built the mastery transcript together, combining the concept of "micro-credentials" emerging in higher education with a version of the digital portfolio - featuring students' work samples - that Looney had discovered at the Lerner medical school. The transcript would reflect students' mastery of competencies in half a dozen curriculum areas selected by their schools, many of them reaching beyond the borders of conventional high school subjects and classrooms. Students might earn mastery credits for "understanding cultural differences" in a school's "global perspectives" curriculum category, for example, by studying non-Western history or by working on immigration issues at a local nonprofit.

In a sharp break with tradition, mastery credits would be based on a school's standards rather than teacher judgment - in the same way that Advanced Placement tests are scored against national AP standards. Students would submit work to teams of teachers and outside experts, earning credit if they met school benchmarks. If not, they'd improve their work and resubmit it, a process stressing student growth. "Grades are teacher-level credits, not institutional credits, and given the arbitrariness of teacher grading, class rankings are absurd," Looney told us.

An early sketch of the transcript looked like a page full of Boy Scout badges. With the help of a Seattle consulting company, Looney settled on a landing page with students' contact information and personal statements, a school profile and a graphic akin to a theater-in-the-round seating chart showing the number of credits students earned in each of their schools' focus areas. It also included summaries of the work students submitted to earn mastery credits - writing, presentations, performances, charts, graphs and photographs, all of which could be uploaded into the transcript and were clickable - as well as a statement of the school's standards, a description of how many advanced credits students at the school typically earn, and teacher comments. There would be no grades.


Looney and Korda knew that if they couldn't get leading colleges and universities to support the mastery model, the transcript and the educational insurgency it represented would be a non-starter. But convincing higher-ed officials wouldn't be easy, given that the traditional transcript, introduced a century ago, was the single most influential component of college admissions.

It meant adding features to the transcript that addressed higher education's concerns, including distinguishing between "foundational credits" that represented graduation requirements and "advanced credits." It also meant that a summary page had to be readable in three minutes, the amount of time admissions officers said they could give the transcript during a first read. The transcripts would live on the MTC website, reached through a student ID number, and they would be printable as PDFs to put in admissions folders - another nod to colleges. (Ultimately, Looney patented the transcript and gave the patent to the MTC.)

But winning over higher education's elites also meant persuading other leading private schools to join his crusade. Private schools educate some 7 percent of the nation's high school students but a third or more of many top colleges' enrollees. And so, Looney reasoned, leveraging their influence could get the Harvards and Stanfords of the world on board while sending a powerful signal to the rest of higher education.

"Higher education takes its signals from the elites, so we had to convince them to take us seriously," he says. Similarly, if he could enlist more brand-name private schools, many other high schools, public and private, would follow, he sensed, in the same way Advanced Placement courses had started in elite private schools and spread throughout public education. "I want to use both the independence that I have as an independent school head and the privilege I have by being proximate to powerful people to put as big a dent in the traditional school model as I can," he told us.

So Looney worked his many private school connections, getting leaders of more than two dozen prominent schools to come to Cleveland in 2016 to hear his transcript pitch. Even he was surprised when nearly every school endorsed his heresy, becoming founding members of his Mastery Transcript Consortium. A second event later that year drew another three dozen top schools.

To convince his Hawken faculty of the value of a transcript that showed a wider range of student talents, Looney blacked out the names on the traditional transcripts of 10 graduating seniors and asked his teachers to identify the students. They couldn't because the students' transcripts were nearly identical. When Looney revealed the students' names and asked the teachers to describe them, they talked at length. "They took the same classes, sat there for the same amount of time, got the same grades, but they were radically different human beings," Looney says.

The Hawken board of trustees didn't need convincing to follow Looney's lead. His enterprising approach had already turned an under-enrolled school with a dispirited faculty into a shining star, with sparkling new buildings, an expanding student body that was more than 30 percent people of color, and Korda's innovative educational experiences. They weren't about to say no to his latest idea.

Saida Brema and Sophia D'Attilio were among the first high school students to use the mastery transcript in college admissions. They were seniors last year at Pathways High, not an elite private school but a racially diverse public charter school housed in a decommissioned Lutheran church on Milwaukee's west side. The mastery transcript was perfect for the ungraded, project-based high school, where students studied election law by drafting voting legislation and learned coding, physics and data analytics by building drones.

D'Attilio, a soft-spoken former gymnast and self-described perfectionist, had met Pathways' minimum of 26 foundational credits across the school's six concentration areas - credits such as historical connections, scientific process and oral fluency. She had also earned nine advanced credits, in topics such as advanced design concepts. She set about constructing her transcript early in her senior year, with the help of a private college counselor provided by her parents, saying in her personal statement that she wanted to "activate the voices of others" - and presenting as samples of her work a podcast she and classmates had produced in a seminar on "Native American Stereotypes in Media and Mascots," background research defending the late-18th-century revolt of enslaved Haitians for a mock trial, and her reflections on producing and directing a school play her junior year.

Despite working as a nanny and teaching gymnastics while attending school, she had everything entered into the MTC portal by November of last year and sent a link to the transcript, along with applications, to a dozen colleges. In December, she was accepted at New York University, one of 4,593 of 17,451 early-decision applicants admitted. She had been anxious about using the gradeless mastery transcript but went ahead with it because, she told us on a Zoom call last winter, "it actually shows you who I am as a person."

NYU agreed. While her transcript required more time to read, the absence of a grade-point average wasn't a problem, says Jonathan Williams, the university's assistant vice president for undergraduate admissions. "The rigor behind a 4.0 grade-point average varies greatly from city to city, school to school, district to district," he says. By offering detailed descriptions of what D'Attilio learned in high school and concrete examples of her work, the mastery transcript provided "a deeper understanding of what kind of learner" she was. "She presented an academic profile that shows that she's smart and thoughtful and committed to learning," he says, "but also a personal profile that's really compelling."



Brema's experience with the mastery transcript was very different. She was born to Sudanese parents in a Kenyan refugee camp and arrived in the States as a 7-year-old speaking Swahili and a bit of English. Her father had been a doctor in Sudan, her mother a health worker, but in Milwaukee her father worked in school transport because his medical credentials weren't recognized. Both parents were busy with six children; Brema had discovered Pathways at a Milwaukee high school fair, and was largely on her own when it came to navigating the college process.

Trying to complete her courses and college applications while working 20 hours a week at a pizzeria and taking care of her 8-year-old brother, she put off organizing her mastery transcript until the last minute. Having to do everything via Zoom during the pandemic didn't help. Nor did the fact that the mastery transcript was new and complicated for Pathways and its seniors to compile in a relatively short time. Pathways' dean of culture spent hours on video conferences with Brema helping her work through it.

She was thinking about applying to nearby Marquette University but didn't get her mastery transcript completed in time; in the end, she applied solely to the University of Wisconsin-Milwaukee, and only after barely meeting the school's deadline. It was, says Brema, who has a sly sense of humor and a wide smile, "a really stressful experience."

But she was happy to be among the 12,584 (out of 14,599 applicants) accepted to the school in the spring. With the university's high admission rate, the question was primarily whether the school would accept Brema's gradeless transcript. It did - and Kathleen Breuer, the admissions coordinator who read Brema's application, told us that the transcript proved helpful, especially after Milwaukee and the dozen other University of Wisconsin schools paused their SAT and ACT testing requirements during the pandemic. While it's easier to judge students with grades, she said, the mastery transcript gave her a clear sense of Brema's writing ability. Plus, Brema's projects coding a computer game and redesigning a classroom "jumped out" at her, demonstrating actual high school work that would have been harder to capture in traditional college applications.

While Pathways' experience with the MTC has had bright spots, it also points to the significant barriers to the transcript's expansion. Even before the school launched the transcript last year, teachers and administrators spent more than a year settling on mastery categories and credits, and ensuring their choices aligned with state education standards - a formidable task for a charter school with ample autonomy, much less a big public school district with many powerful voices. Chicago Public Schools, the nation's third largest district, recently left the mastery transcript out of a school reform project after weighing the work needed to put it in place - and the radical rethinking that would be required of administrators, teachers, parents and students - according to the project's manager, Damarr Smith. "It's a lot harder at a district with over 300,000 students," he says. "How do you bring all the stakeholders together in an equitable way?"

There's also the challenge of training teachers to judge students' work against school mastery standards. Plus, giving students a stake in their transcripts by having them assemble work samples is another heavy lift. Small schools like Pathways and pricey private schools may have the staff to help students, and some students like D'Attilio may have the resources for private counselors. In many public high schools, though, students are on their own, and there aren't enough guidance counselors to go around. "The solution is building advisory systems," says Pathways director Kim Taylor, "with each teacher helping a dozen or so students with their transcripts, starting in the ninth grade." Still, the prospect of large, under-resourced schools managing a thousand or more students' work on mastery transcripts is daunting.

Another hurdle: state regulations tying education funding to school-based learning and mandating substantial numbers of courses in traditional academic subjects. Washington state education authorities, for example, initially wouldn't fully fund an MTC school for the time students spent off-campus learning at a Boeing jet engine plant. Yet increasing numbers of states are granting high schools greater flexibility in how they award graduation credits, and the shuttering of schools during the pandemic is likely to intensify the trend by forcing policymakers to think more flexibly about how and where students learn. What's more, the MTC says there's no reason the mastery transcript can't be used in high schools with conventional courses - as long as schools replace grades with mastery credits.

Perhaps the bigger challenge, research by the Carnegie Foundation for the Advancement of Teaching suggests, is a persistent adherence to traditional education practices. Vermont's largest public high school, in Champlain Valley, abandoned a mastery transcript pilot program last year in the face of the pandemic, but also because school leaders sensed the affluent community wasn't yet ready to do anything that might alter students' college prospects.




The higher education side of the equation isn't any easier. Persuading colleges and universities to embrace the mastery transcript isn't just about admissions, but also scholarships and sports eligibility.

The National Collegiate Athletic Association requires courses, grade-point averages and SAT or ACT scores (suspended during the pandemic) of high-schoolers hoping to play Division I or II sports, as do many state-sponsored scholarship programs. The prestigious, 280,000-student University of California system bases admissions decisions on courses, grades, class rank and, until recently, test scores. Several of the system's campuses admitted MTC students to this fall's first-year class, but through a narrow "admission by exception" policy. And some state universities receiving vast numbers of applications simply won't read those lacking GPAs. "The minute you move away from a formula, it becomes a lot harder and more expensive for institutions," says Angel Pérez, the chief executive of the National Association for College Admission Counseling.

The MTC is working hard to address these challenges. The organization holds weekly open houses via Zoom for admissions officers and reaches out to introduce the mastery transcript to the top five college choices of every MTC student.

And there has been progress. Beyond the 170 colleges and universities admitting students with mastery transcripts last year, the NCAA told us that its eligibility staff would work with schools sending mastery transcripts to translate them into course and grade equivalencies. And many states are willing to provide flexibility in their scholarship programs; lawmakers in Utah, North Dakota and West Virginia have directed their public higher education systems to put alternative transcripts on equal footing with regular transcripts in awarding scholarships.

All this points to a growing sentiment in higher education that Looney is right in arguing that current admissions metrics don't do justice to students' unique talents. "Young people are much more complicated than the model of 'grades plus test score equals success' suggests," says Pérez. While some commentators warn that the gradeless mastery transcript could hurt students with top GPAs in lesser-known high schools, Pérez, who sits on the MTC's higher education advisory board, believes the mastery transcript may help get more underrepresented students into the college pipeline. "Many disadvantaged students may not shine in a rigid testing environment but may shine in other ways," he says.

The decision by many colleges and universities to temporarily abandon SAT and ACT admissions testing during the pandemic has fueled that prospect. "The mastery transcript provides a lot more space for students to articulate different ways that they've learned," Kay Eilers, the University of Wisconsin-Milwaukee's associate vice chancellor of enrollment management, told us. "From an equity lens, there's so much value in students being able to describe their skills and abilities in a variety of ways." And Looney argues the transcript isn't just a better tool for high school students heading to college. "It helps identify themes and threads for career development or trade development," he says, qualities like teamwork and resilience that are important to employers.

Looney isn't naive about the challenges he faces in competing with a deep-rooted element of the education landscape. In his first pitch to private school leaders at the Cleveland Botanical Garden, he suggested they build project-based programs alongside their existing schools because it could take years to transition to high-quality mastery models. But he's undeterred. He launched his project-based school - the Mastery School at Hawken - last fall with three dozen ninth- and 10th-graders near Cleveland's arts district, surrounded by scores of nonprofit organizations offering a wide range of learning opportunities. He envisions the school becoming a 180-student test site for educators around the country to learn from.

When we visited in the spring, teams of students had been studying why caffeinated water wasn't selling in local convenience stores and how to reduce vandalism in abandoned homes in a nearby neighborhood. We attended a session that introduced students to mastery credits and the mastery transcript, giving them the building blocks of this model early in their high school careers - a key to the transcript's success, Looney believes.

It's too early to know how MTC students are doing in college, much less how widely the mastery transcript will travel. The prominent private schools that lent their names to Looney's campaign early on have trailed public charter schools and upstarts in the private sector in launching the mastery transcript, MTC officials say. Elite schools are eager to endorse the work and engage with the consortium's new ideas but have been slowed by old definitions of educational excellence among faculty, boards of trustees and parents. Regardless, Looney's not taking his big bet on the mastery transcript off the table.

"We need another way to see kids," he says, "one that reflects who they really are and what they really learn."

CASCADE, Mont. (AP) — For the first time in 30 years, the Census has awarded Montana a second seat in Congress. On paper, that leaves the state's redistricting commission with the easiest task of all its counterparts across the country: Divide the expansive state in half.

If only.

Nothing is ever that simple in redistricting battles, as political parties jostle for control over maps that will give their candidates an advantage and the simple act of drawing a line becomes a fraught battle over the identity of the state.


In Montana, Republicans are pushing to separate the two booming college towns of Bozeman and Missoula in the western half of the state. Putting the two Democratic-leaning communities in different districts would make it hard for Democrats to win either seat. Democrats want to consolidate their strongholds in one district that would give them a fighting chance to win a House seat. They argue the towns — filled with craft brew drinkers, liberal academics, remote workers and California transplants — share more in common with each other than the vast expanse of rural ranches and farms between them.

The bipartisan commission is set to select the district boundaries on Thursday. With little common ground between the commission’s two Republican and two Democratic members, much of the decision may fall on the nonpartisan chairperson, Maylinn Smith, who was appointed to the commission by the state's Supreme Court.

She has a history of giving small donations to Democratic political candidates in the state, but has said her experience working as a judge in several tribal court systems has given her the ability to act impartially.

To Republicans, there's a simple solution — a neat line splitting the state into eastern and western districts that puts Bozeman in the eastern one and Missoula in the western one. They contrast that with the more tortured route Democrats propose to lump the two cities together.

“When you have a shape that isn’t even a shape, it’s looks like the C from the Cookie Monster, that is not a reasonable district,” said Jennifer Carlson, a Republican state lawmaker from a town 20 minutes outside Bozeman, during a meeting of the commission on Tuesday.

Earlier in the meeting fellow Republican lawmaker Derek Skees held up a pumpkin carved with one of the maps proposed by Democrats, jeering at its unusual borders.

But Democrats say it's not that simple. Terry Cunningham, deputy mayor of Bozeman, notes that his city along with Missoula and the state capital of Helena are the only three in the state that have voted for carbon reduction goals while much of the rest of the state depends on the fossil fuel industry.

“I believe it is immoral to add new fossil fuel burning resources to the mix,” Cunningham said. “Other communities in Montana would vehemently object (to our goals) because fossil fuel extraction is part of their lifeblood. So those make us incompatible politically with what could be described as the number one issue facing the entire planet.”



Part of the reason Montana gets a second congressional district is the population growth fueled by Bozeman, a city of 50,000 that has become a hotbed for startups and pandemic-era remote workers. Home to Montana State University, Bozeman grew a whopping 33% in the last decade, growth that dwarfs that seen anywhere else in the state.

Its downtown is packed with pedestrians wearing the latest moisture-repelling microfibers, boutique bakeries and upscale restaurants. Housing prices have skyrocketed, as has homelessness. Missoula, home to the University of Montana, has similar headaches.

Democrats in the two cities argue that their common situation cries out for them being in the same district, which would likely lean only slightly Republican and therefore be competitive in a state where the beet-red hue of its rural swathes has tilted it solidly toward the GOP.

“In order for democracy to function well in the United States, you need to have a political system that is responsive to the electorate’s desires,” said Jeremy Johnson, a political scientist at Carroll College in Helena. In safe districts, “there is less incentive for legislators to listen to constituents.”

Republicans argue that the way they slice up the state would still preserve competition. Still, both seats would lean GOP, in part because of the changes since the last time Montana had two congressional seats.


In the 1990 census, Montana's population growth slowed so much that it lost its second seat and began electing a single representative for the entire state. That seat has been held by Republicans for the past 24 years as rural areas that once voted Democratic became more conservative, leaving the blue islands of Bozeman and Missoula surrounded by vast expanses of red.

“You don’t have to go far from city lines when you’re really in ruby red Republican territory across most of the state,” Johnson said.

But not all towns fit neatly into the redistricting arguments laid out by Republicans and Democrats. The town of Cascade 115 miles north of Bozeman falls alternatingly in eastern and western districts proposed by both Democrats and Republicans. Home to around 700 people, Cascade is sandwiched between an interstate highway on one side and the Missouri River on the other and surrounded by farms and ranches.

In contrast to Bozeman, its sparse main street holds only a handful of businesses, including a couple restaurants, a market, a gas station, a fly fishing shop and a bank. Incorporated 110 years ago, Cascade has changed little since then -- aside from a recent upgrade of the town’s water and sewage pipes.

The contrast with Bozeman is obvious to the town's residents.

“There are two Montanas -- socially, economically, culturally -- we are two states,” said Ken Speidel, who owns a horse boarding business with his wife, Kelly, in the rural town and works as a river guide in the summer and a hockey referee in the winter.

Like many in Cascade, Speidel favors the Republican proposals. But he acknowledges the power of counterarguments.

“There is no solution that is going to make everybody happy,” he said.

A meteor that incinerated the residents of an ancient city inspired the biblical story of Sodom, research suggests

In the biblical story of Sodom, God destroys the city and its inhabitants due to their wickedness.


A study suggests the tale was inspired by a meteor that wrecked the ancient city of Tall el-Hammam.


A 165-foot meteor exploded in the sky there 3,600 years ago, incinerating people and homes.

About 3,600 years ago, residents of the city of Tall el-Hammam started their days like any other. A guard likely sat on the parapet atop the local palace.

Then, to the southwest, an object fell through the sky.

"All of a sudden, this thing explodes in a sudden burst of light," researcher Malcolm LeCompte told Insider. "The guard's instantly blinded. He's done."


The heat from the explosion melted the bricks beneath the guard. A shockwave followed, which sheared off the top 40 feet of the palace roof and, presumably, liquefied his insides.

That explosion, according to a study LeCompte co-authored last month, was a 165-foot-wide meteor that blew up before hitting the ground, annihilating the city. The blast killed at least 8,000 people and animals.

"It was essentially a mini-sun," LeCompte said. "And if the heat didn't kill you, the shockwave would've be sufficient to basically tear you apart and turn you into nothing but a bag of bones or goo."

He and his colleagues think the saga of Tall el-Hammam could have inspired the biblical tale of Sodom. The disaster bears an uncanny resemblance to Moses' account in the book of Genesis, in which he warns against acts of wickedness by describing a city and its sinful people that God destroyed in a firestorm.

Archaeologists already knew that Tall el-Hammam, located in a valley in present-day Jordan, was suddenly abandoned millennia ago and remained uninhabited for centuries. Yet the reason for its demise remained up for debate - some historians suggested a natural disaster or violent war. But the new research, a culmination of 15 years of excavation, reveals that the city and its residents were subject to extreme temperatures and pressures.

LeCompte, who researches meteors and their impacts at Elizabeth City State University, said the only thing that can explain it is an extraterrestrial impact.

"An earthquake couldn't do that," he said.
A layer of melted pottery and glass tells a tale of destruction

Excavations at Tall el-Hammam began in 2005. Archaeologists first uncovered pottery, buildings, and bodies.

But then they started finding evidence that things had gotten really hot, really fast - like a rock that had melted to black on all sides, remnants of melted pottery and metal, and glass that had liquefied and splattered onto fragments of human bones.

Glass melts starting at 2,500 degrees Fahrenheit. Iron and pottery's melting points are even higher.

"The technology didn't exist at that time, in the Middle Bronze Age, for people to be able to generate fires of that kind of temperature," Sid Mitra, a geologist from East Carolina University who coauthored the study, said in a press release.

Thinking a space rock could be the explanation, excavators called in LeCompte and other members of his international Comet Research Group in 2014.

Malcolm LeCompte

Over the next seven years, LeCompte visited the site three times to collect samples. Multiple findings by his team confirmed that a cosmic airburst had happened near the city.

In a layer of sediment dating back 3,600 years, the group found fractured sand grains - known as shocked quartz - which only form at very high pressures. Those pressures had also converted wood and plants in the city into microscopic diamonoids that are almost indestructible.

Additionally, the group found dust-like particles called spherules composed of vaporized iron and sand. Spherules form at about 2,900 degrees Fahrenheit.

The sediment layer also contained platinum, iridium, and osmium - some of the rarest elements on Earth, which often come from meteorites.
People in the area were blinded, deafened, or smushed

Yet another indication that a meteor was responsible is that city buildings, including the palace, all fell toward the northeast.

"It appears things were destroyed directionally," LeCompte said.

This suggests the space rock exploded to the southeast of the city, and the resulting shockwave traveled north.

Meteors that explode in the atmosphere before striking Earth's surface are called bolides. Their cosmic airbursts can be more powerful than a nuclear bomb. The explosion above Tall el-Hammam, LeCompte said, had a yield between 5 and 30 megatons - at least 330 times more powerful than the atomic bomb that destroyed Hiroshima.

The air temperature rose to 3,600 degrees Fahrenheit (2,000 degrees Celsius). Those who looked at the incoming meteor lost their sight.

"More than likely, everything that was burnable would've caught fire, like wood and clothes," LeCompte said. "If you were on a hillside looking down into the valley, the sound of the explosion might've broken your ear drums."

Then came the shockwave, which would have felt like an intense wind barreling in at 740 miles per hour.

"The shock that would pass through your body would make mush out of your insides," LeCompte said.

He added that the pressure from the wind would have been 100,000 times what we normally feel.

Indeed, in Tall el-Hammam archaeologists unearthed bodies that were missing legs and skulls. Some victims had been blown against the walls of rooms and buried under rubble. Many of the people likely died without knowing what had happened, LeCompte said, incinerated by the blast.

The study suggests that the explosion was similar to that of a bolide over Russia more than a century ago. That event resulted in minimal human casualties due to its remote location in Sibera, but destroyed 800 square-miles of forest, knocking down 80 million trees.
The impact may have splashed salt from the Dead Sea into the soil

In the Sodom story, God leaves nothing alive - wiping out even "that which grew upon the ground."

The researchers' findings also offer an explanation for that line: They observed a high concentration of salt in the sediment layer, which would have been toxic to crops.

If the meteor exploded southwest of Tall el-Hammam, it may have vaporized or splashed water from the nearby Dead Sea into the surrounding soil.

Historical records show that this area of the Middle East was abandoned for up to 600 years following the disaster - which would have been the only option if salty soil had made agriculture impossible.

S Korea test launches 1st domestically made space rocket ICBM

SEOUL, South Korea (AP) — South Korea test launched its first domestically produced space rocket on Thursday in what officials describe as an important step in the country’s pursuit of a satellite launch program.

It wasn’t immediately clear whether the three-stage Nuri rocket succeeded in delivering a dummy payload – a 1.5-ton block of stainless steel and aluminum – into orbit 600 to 800 kilometers (372 to 497 miles) above Earth.

Live footage showed the 47-meter (154 foot) rocket soaring into the air with bright yellow flames shooting out of its engines following blastoff at Naro Space Center, the country’s lone spaceport, on a small island off its southern coast.

The launch, which was observed by South Korean President Moon Jae-in, was delayed by an hour because engineers needed more time to examine the rocket’s valves. There had also been concerns that strong winds and other conditions would pose challenges for a successful launch.

Officials at the Korea Aerospace Research Institute, the country’s space agency, said it would take about 30 minutes to determine whether the rocket successfully delivered the payload into orbit.

Nuri’s largest first stage, the core booster stage, was expected to land in waters southwest of Japan after separation, and its second stage was expected to fall in remote Pacific waters east of the Philippines, about 2,800 kilometers (1,740 miles) away from the launch site. The smallest third stage carries the payload and is designed to place it into orbit.

After relying on other countries to launch its satellites since the early 1990s, South Korea is now trying to become the 10th nation to send a satellite into space with its own technology.

Officials say such an ability would be crucial for the country’s space ambitions, which include plans for sending more advanced communications satellites and acquiring its own military intelligence satellites. The country is also hoping to send a probe to the moon by 2030.

Nuri is the country’s first space launch vehicle built entirely with domestic technology. The three-stage rocket is powered by five 75-ton class rocket engines placed in its first and second stages.

Scientists and engineers at KARI plan to test Nuri several more times, including conducting another launch with a dummy device in May 2022, before trying with a real satellite.

South Korea had previously launched a space launch vehicle from the Naro spaceport in 2013, which was a two-stage rocket built mainly with Russian technology. That launch came after years of delays and consecutive failures. The rocket, named Naro, reached the desired altitude during its first test in 2009 but failed to eject a satellite into orbit, and then exploded shortly after takeoff during its second test in 2010.

It wasn’t clear how North Korea, which had been accused of using its space launch attempts in past years as a disguise for developing long-range missile technology, would react to Thursday’s launch.

While pushing to expand its nuclear and missile program, the North had shown sensitivity about South Korea’s increasing defense spending and efforts to build more powerful conventionally armed missiles.

In a speech to Pyongyang’s rubber-stamp parliament last month, North Korean leader Kim Jong Un accused the U.S. and South Korea of “destroying the stability and balance” in the region with their allied military activities and a U.S.-led “excessive arms buildup” in the South.

While Nuri is powered by liquid propellants that need to be fueled shortly before launch, the South Koreans plan to develop a solid-fuel space launch rocket by 2024, which possibly could be prepared for launch more quickly and also be more cost effective.

South Korea space rocket test prompts fear of arms race with North

Tensions between Seoul and Pyongyang have grown in recent months. South Korea's failed test of its first-ever homegrown rocket has prompted worries of a new arms race

Shortly after 5 p.m. local time (0800 UTC) on Thursday, South Korea launched its first domestically produced rocket from the Naro Space Center in the northeastern county of Goheung.

All three stages of the liquid-fueled Nuri rocket, which cost around 2 trillion won ($1.7 billion, €1.46 billion), worked but the rocket reportedly failed to complete the mission of delivering a test satellite into orbit.

South Korean President Moon Jae-in said the rocket reached an altitude of 700 kilometers (435 miles), and that the 1.5 ton payload separated successfully.

However, Moon said that "putting a dummy satellite into orbit remains an unfinished mission."

Despite the test being unable to fulfill its task of putting a satellite into orbit, the launch comes as South Korea is locked into a growing rivalry with North Korea over technological advances in weaponry.

South Korean President Moon Jae-in called the test an "excellent accomplishment,'' taking South Korea a step further toward a space launch program.

North Korea submarine missile test was planned, experts think

South Korea's launch of the Nuri rocket has long been planned. Analysts said it was no coincidence that North Korea on Tuesday carried out what it claims was the first launch of a ballistic missile from a submerged submarine (SLBM).

The test launch was conducted off the naval base on the west coast of the peninsula. It was the eighth time that the North has carried out a missile launch this year.

It also coincided with the five-day Seoul International Aerospace and Defense Exhibition, where South Korean President Moon Jae-in was pictured in a flight suit and in the cockpit of a domestically produced FA-50 fighter jet.

Speaking to reporters, Moon said it is imperative for South Korea to build up its defenses: "A strong defense capability is always aimed at ensuring peace."

"The Republic of Korea seeks to build a smart and strong armed forces based on state-of-the-art technology," he added.
North justifies military buildup

Exactly one week earlier, North Korean leader Kim Jong-un attended a defense development exhibition in the North's capital Pyongyang to mark the 76th anniversary of the founding of the Workers' Party, issuing a similar justification for his own military buildup.

"We must be powerful for our coming generations as well," the state-run Korea Central News Agency (KCNA) quoted Kim as saying. "That is our first and foremost task."

"The military danger facing our state daily to the military tension prevailing around the Korean peninsula is different from 10 or five, even three years ago," he said.

Kim blamed "the unstable situation in the region" on the United States.


North Korea confirmed it had tested a new type of submarine-launched ballistic missile

In late September, the North tested what it claimed was an advanced new hypersonic missile.

US defense analysis suggests that Pyongyang may resume underground nuclear tests or fire a long-range ballistic missile within the next year.

Both would be violations of United Nations Security Council resolutions. But Pyongyang insists that its military developments are purely defensive and necessary as its enemies — primarily the US, South Korea and Japan — remain committed to overthrow of the Kim regime.

Those countries deny that they are planning a regime change in North Korea. But they all point out that they cannot sit by as a nuclear-armed and deeply unpredictable neighbor continues to build out its military capabilities.

South Korea tested its own submarine-launched ballistic missile recently, and is investing heavily in improved equipment on land, sea and air.

Significantly, the Korean navy is pushing ahead with plans to build the nation's first aircraft carrier. Meanwhile, discussions are also underway about the possibility of developing a nuclear-powered submarine.
North Korea 'careful not to cross red lines'

"The North just tested its first hypersonic missile and has now launched an SLBM, so it seems that they are showing the South and the rest of the world just what they can do," said June Park, a political economist with Princeton University.

"South Korea cannot just sit by and let that happen, so the Seoul defense show is a chance to demonstrate, 'we also have the ability to defend ourselves,'" she told DW.

Robert Dujarric, co-director of the Institute of Contemporary Asian Studies at the Tokyo campus of Temple University, says there has been an uptick in saber-rattling after a period of relative restraint on the Korean Peninsula. But he said Pyongyang is very aware where the "red line" lies.

"Ever since the armistice at the end of the Korean War in 1953, we have seen these periodic bouts of development of new weapons in the North — such as nuclear tests and then intercontinental ballistic missile launches — but the North has been very careful to not go too far, to not cross any red lines," he said.

"They have caused small-scale border incidents and been provocative and made a nuisance of themselves — but they have never gone too far as they know that crossing that red line would bring down a massive US retaliation," he said.

Just a phase?

"I think we are in that cycle again, and it must be remembered that it is one thing to parade a new missile through Pyongyang or to carry out a test launch, but it's an entirely different thing to fire one of these things in an operational situation," Park explained.

Unfortunately, says Park, the North's development of nuclear weapons gives the South little leeway in where to advance its own military capabilities in the years to come.

South Korean people are split almost half-and-half on the question of whether or not to develop a domestic nuclear deterrent, she said.

Should that happen, however, the reverberations would be felt far beyond North Korea and could arguably destabilize the entire northeast Asian region, where Russia, China and Japan are also major powers, Park explained.

Vienna museums resort to OnlyFans for cultural naked truth

Vienna's Albertina museum is one of several to have social media sites judge some pieces, including in current exhibition of Italian artist Amadeo Modigliani, too "explicit" JOE KLAMAR AFP


Vienna (AFP)

An inspired publicity coup on the part of Vienna's tourist board, the OnlyFans account has won several hundred subscribers since its launch last month.

But the office's director Norbert Kettner says the move is mostly meant to "start a debate about censorship in the arts and the role of algorithms and social networks in the arts".

Kettner says the idea was born of museums' frustrations at the "difficulties when they are promoting exhibitions" due to the strict criteria some social media platforms use when deciding what counts as pornographic.

A notorious example was Facebook's censoring in 2018 of the prehistoric "Venus of Willendorf" figurine on display in Vienna's Natural History Museum, considered a masterpiece of the paleolithic era.

Kettner brands the decision "bizarre" and Facebook itself later apologised for the "error".

'Provocative character'

"It seems almost strange or even ridiculous" that the nude body is still a subject of controversy, says Klaus Pokorny, spokesman for the city's Leopold Museum.

"It should be very natural but it is not at all," he adds.

The museum boasts a key collection of work by early 20th-Century painter Egon Schiele, whose paintings frequently fall foul of social media censorship.

One of Vienna's other star art attractions, the Albertina, has had pieces in its current exhibition dedicated to Italian artist Amadeo Modigliani likewise judged too "explicit" by some sites.

Pokorny says such incidents have "forced" museums to explore alternatives.

"We did not want to open an account on OnlyFans... but it happened because the most well known international platforms like TikTok, Facebook or Instagram did not accept our works," he says.

Kettner says it's almost as if when it comes to taboos around the human body "we are pretty much the same as 100 years ago".

Social media censorship has also hit work by Austrian painter Egon Schiele, whose "L'Etreinte" is pictured here AFP

Art historian and director of France's Hartung-Bergman Foundation Thomas Schlesser describes the OnlyFans account as a "shrewd" move.

It means "the work regains the provocative or even pornographic character that they could have had when they were first produced," he told AFP.
'Self-censorship'

The issue goes far beyond the high art canon, according to Kettner.

"Many young artists depend on their online channels and many of them are already thinking: what is it possible to post there?" he points out, warning this can lead to a "sort of unconscious self censorship".

Several social media sites have said their rules on explicit content have evolved and now make exceptions for works of art.

However, Olivier Ertzscheid, specialist in information technologies at Nantes University, says despite these ostensible efforts "the reality is that when it comes to the representation of the body (especially female bodies) nothing has really changed, whether or not it's in an artistic form".

For Ertzscheid, sites' policies on nudity are part of a sort of "marketing of prudishness" in order to present the sites as safe and suitable for all.

Facebook did not respond to a request for comment from AFP on the Viennese initiative.

As for whether the museums could make headway in changing platforms' policies, Kettner says he hopes for direct discussions with them but has not yet been approached.

OnlyFans has become a popular platform for creators of erotic content but recently itself had to back down on a planned ban on sexually explicit content after an outcry from performers 
Lionel BONAVENTURE AFP

He has no qualms about being linked to OnlyFans, a site which has become known in recent years as a popular platform for creators of erotic content.

In August, OnlyFans itself had to back down on a planned ban on sexually explicit content after an outcry from performers.

For Pokorny, the move onto the platform is "not a question of our success on social media but a question of principles".

He describes it as "a war by other means", a "fight for our rights, for freedom, for love, for understanding and not for restrictions and people who want to influence our lives".

Paris pushes vision of '100-percent bikeable' city

Issued on: 21/10/2021 - 

Paris city hall wants more of this - AFP


Paris (AFP)

Socialist mayor Anne Hidalgo, who runs Paris with support from the Green party, placed a push for more bike-friendly policies at the centre of her platform that got her re-elected by a wide margin in June of last year.

She is now also the Socialist party's candidate in next year's presidential election, hoping to unseat President Emmanuel Macron, but her campaign has got off to a woeful start with single-digit ratings.

Her policies have found wide support among the capital's urban elites with short commutes, but they are seen as a much harder sell in the rest of the country.

"Our target is to make our city 100 percent bikeable," David Belliard, deputy mayor in charge of urban transformation and Green party member, told AFP.

Some 180 million euros of new spending is earmarked for infrastructure, including plans for major bike routes across the city and into surrounding suburbs, and additional measures to make crossings and key entry points into inner Paris safer for cyclists, Belliard said.

Some flashpoints will get dedicated paths for cyclists and pedestrians completely separate from any car traffic, he added.

The city already spent 150 million euros on an initial biking plan, calling this the start of a "revolution" for the capital.

An added sense of urgency came with the Covid-19 pandemic that sparked a rapid extension of the city's cycling path network, dubbed "corona-pistes", as commuters shunned public transport for fear of infection.

As part of the new plan, those lanes, often hastily built to meet sudden demand, are to be made permanent and secure.

By 2026 the Parisian network of safe cycling paths is to total 180 kilometres (112 miles). Cyclists will be allowed to use one-way streets against oncoming car traffic on another 390 kilometres of streets.
Bike-friendly Paris?

The mayor's bike-friendly policies have sparked anger from motorists, with decisions such as turning stretches of urban motorways along the river Seine over to bikes and pedestrians.

Paris now often makes it into the top leagues of the world's most bike-friendly cities, ahead of any other mega-city, although still well behind European cycling models Copenhagen and Amsterdam.

The city also plans to help prevent bike theft, which Belliard said was "one of the obstacles to bicycle use".

By 2026, he said, Paris would have 100,000 new dedicated parking spots for bikes, of which 40,000, notably near train and metro stations, would be guarded.

Paris will also curb inner-car traffic further, aiming to end cross-city car transit completely, and cutting car traffic by half in a designated city centre zone.

Schools in the capital are to boost bike training to ensure that "all young Parisians know how to ride a bike when they leave primary school", Belliard said.

Hidalgo, who will also face Green candidate Yannick Jadot in the election, is now looking to kickstart her flagging presidential campaign with a rally in the city of Lille on Sunday.

Sudan protest: Rival camps take to the streets as tensions rise in central Khartoum

Issued on: 21/10/2021 - 



Tens of thousands of supporters of Sudan's transition to a civilian-led democracy took to the streets Thursday, as rival demonstrators kept up a sit-in demanding a return to military rule. Both sides appealed to their supporters to keep apart and refrain from any violence, but there was a heavy police and troop presence around potential flashpoints.
