An anonymous reader quotes a report from Wired: Arkady Volozh, the billionaire cofounder of Russia's biggest internet company, was removed from the EU sanctions list today, clearing the way for his return to the world of international tech. On Tuesday a spokesperson for the European Council confirmed to WIRED that the Yandex cofounder was among three people whose sanctions were lifted this week. Volozh, 60, was initially included on the EU sanctions list in June 2023, following Russia's full-scale invasion of Ukraine in February 2022. "Volozh is a leading businessperson involved in economic sectors providing a substantial source of revenue to the Government of the Russian Federation," the blocsaidlast year to justify its decision. "As founder and CEO of Yandex, he is supporting, materially or financially, the Government of the Russian Federation." In response, Volozh stepped down from his position as Yandex CEO, calling the sanctions "misguided." [...]

The removal of sanctions affecting one of Russian tech's most prominent figures will be especially significant if Volozh goes on to build Yandex 2.0 inside Europe. The billionaire maintains strong ties to exiled Russian tech talent, with thousands of Yandex staff leaving the country after the start of the war. "These people are now out, and in a position to start something new, continuing to drive technological innovation," Volozh said in the same 2023 statement. "They will be a tremendous asset to the countries in which they land." Yandex is widely known as "Russia's Google" because it monopolizes the Russian search market and offers many other services, including Yandex Music for streaming, Yandex Navigator for maps, and Yandex Go for hailing a ride. "Over the past 18 months, [Dutch-based Yandex NV] has been involved in complex negotiations with the Kremlin, in an attempt to sell its Russian operations while carving out four Europe-based units, which include businesses focused on self-driving cars, cloud computing, data labeling, and education tech," reports Wired.

Last month, Yandex NV reached a "binding agreement" to sell its operations in the country for $5.2 billion -- a price that reflects a 50% discount that Moscow imposes on companies from "unfriendly" countries like the Netherlands as a condition of exiting business in Russia.

The University of Texas at Austin said Monday that it would again require standardized tests for admissions (non-paywalled source), becoming the latest selective university to reinstate requirements for SAT or ACT scores that were abandoned during the pandemic. From a report: A few years ago, about 2,000 colleges across the country began to move away from requiring test scores, at least temporarily, amid concerns they helped fuel inequality. But a growing number of those schools have reversed those policies, including Brown, Yale, Dartmouth, M.I.T., Georgetown and Purdue, with several announcing the changes in recent months.

U.T. Austin, which admits a cross-section of high-achieving Texas students under a plan designed to increase opportunity in the state, cited a slightly different reason than the other schools in returning to test requirements. Without requiring test scores, officials said, they were hampered in placing the admitted students in programs they would be most suited for and in determining which ones needed extra help. After making test scores optional the past few years, the university will now require applicants to submit either SAT or ACT scores beginning Aug. 1, with applications for fall 2025 admissions.

In an interview, Jay Hartzell, the U.T. president, said that the decision followed an analysis of students who did not submit scores. "We looked at our students and found that, in many ways, they weren't faring as well," Dr. Hartzell said. Those against testing requirements have long said that standardized tests are unfair because many students from affluent families use tutors and coaches to bolster their scores. But recent data has raised questions about the contention. In reinstating test requirements, some universities have said that making scores optional had the unintended effect of harming prospective students from low-income families.

Roughly $138 billion in U.S. student loan debt has now been cancelled, reports CNN. "That's about one-third of the $430 billion that would've been canceled under the president's one-time forgiveness plan, which was struck down by the Supreme Court last year."

It's 9% of all outstanding federal student loan debt, according to the article, "wiping out debts for about 3.9 million borrowers — by using a number of existing programs that aim to offer debt relief for certain groups of struggling borrowers..." What President Biden has been doing — before and after the Supreme Court ruling — is using existing student loan forgiveness programs to deliver relief to certain groups of borrowers, like public-sector workers (through the Public Service Loan Forgiveness program) and borrowers who were defrauded by their college (through the borrower defense to repayment program). His administration also made discharges for borrowers who are totally and permanently disabled. None of these programs expire, meaning they will help qualifying borrowers now and in the future. In some cases, Biden's administration has expanded the reach of these programs, making more borrowers eligible.

And in other cases, it has made an effort to correct past administrative errors made to borrowers' student loan accounts by conducting a one-time recount of borrowers' past payments. This effort helps make sure people receive the loan forgiveness they may already qualify for by having made at least 20 years of payments in an income-driven plan, which calculates monthly payment amounts based on a borrower's income and family size, rather than the amount owed. The recount is expected to be completed by July...

Last year, the administration created a new income-driven repayment plan. Known as SAVE, the new plan offers the most generous terms for low-income borrowers. Those who originally borrowed $12,000 or less will see their remaining debt canceled after making payments for at least 10 years... [The administration] is working on implementing another path toward a broad student loan forgiveness program, this time relying on a different legal authority in hopes that this attempt holds up in court. This proposal is currently making its way through a lengthy rulemaking process and has yet to be finalized.

Schools are widely adopting a new tool called Writable that uses ChatGPT to help grade student writing assignments. Axios reports: Writable, which is billed as a time-saving tool for teachers, was purchased last month by education giant Houghton Mifflin Harcourt, whose materials are used in 90% of K-12 schools. Teachers use it to run students' essays through ChatGPT, then evaluate the AI-generated feedback and return it to the students.

A teacher gives the class a writing assignment -- say, "What I did over my summer vacation" -- and the students send in their work electronically. The teacher submits the essays to Writable, which in turn runs them through ChatGPT. ChatGPT offers comments and observations to the teacher, who is supposed to review and tweak them before sending the feedback to the students. Writable "tokenizes" students' information so that no personally identifying details are submitted to the AI program.

An anonymous reader quotes a report from The Guardian: The average toddler is missing out on hearing more than 1,000 words spoken by an adult each day due to screen time, setting back their language skills, a first-of-its kind study has found. The research, published on Tuesday in the Journal of the American Medical Association (Jama) Pediatrics, tracked 220 Australian families over two years to measure the relationship between family screen use and children's language environment. Families recorded all the audio around their child using advanced speech recognition technology over a 16-hour period on an average day at home. They repeated this process every six months between the ages of 12 and 36 months. The lead researcher, Dr Mary Brushe from the Telethon Kids Institute, said: "The technology we use is essentially like a Fitbit, but instead of counting the number of steps, this device counts the number of words spoken by, to and around the child." The device also picked up electronic noise, which the researchers analyzed to calculate screen time.

The researchers found young children's exposure to screens including TVs and phones was interfering with their language opportunities, with the association most pronounced at three years of age. For every extra minute of screen time, the three-year-olds in the study were hearing seven fewer words, speaking five fewer words themselves and engaging in one less conversation. The study found the average three-year-old in the study was exposed to two hours and 52 minutes of screen time a day. Researchers estimated this led to those children being exposed to 1,139 fewer adult words, 843 fewer child words and 194 fewer conversations. Because the study couldn't capture parents' silent phone use, including reading emails, texting or quietly scrolling through websites or social media, Brushe said they might have underestimated how much screen usage is affecting children.

A language-rich home environment was critical in supporting infants and toddlers' language development, Brushe said. While some educational children's shows were designed to help children's language skills, very young kids in the age group of the study could struggle to translate television shows into their own life, she said. This study did not differentiate between whether children were watching high- or low-quality screen content.

The SAT, a college admissions exam that for nearly a century was completed using paper and pencil, is now officially all-digital. From a report: This week, students in the U.S. will begin taking the new SAT on their own devices -- including a tablet or a laptop -- or on school devices. The test is also one hour shorter (down from three hours), has shorter reading passages and uses digital tools, like a highlighter, a graphing calculator and a bookmark to go back to skipped questions. The revamped test, which ditches the paper and pencil, aims to make cheating harder and grading easier.

Students will still take the exam at a test center or at a high school. "Today's students, they do a lot of their living digitally, they do a lot of their learning digitally and they do a lot of their test taking digitally," says Priscilla Rodriguez, who oversees the SAT for the College Board, the organization behind the test. Throughout March and April, the College Board expects more than 1 million students to take the new digital SAT. Students can take the exam on Saturday test dates or during SAT School Days, where participating high schools offer the test to upperclassmen free of charge during the school day.

Long-time Slashdot reader theodp writes: CACM [Communications of the ACM] Is Now Open Access," proclaims the Association for Computing Machinery (ACM) in its tear-down-this-CACM-paywall announcement. "More than six decades of CACM's renowned research articles, seminal papers, technical reports, commentaries, real-world practice, and news articles are now open to everyone, regardless of whether they are members of ACM or subscribe to the ACM Digital Library."

Ironically, clicking on Google search results for older CACM articles on Aaron Swartz currently returns page-not-found error messages and the CACM's own search can't find Aaron Swarz either, so perhaps there's some work that remains to be done with the transition to CACM's new website. ACM plans to open its entire archive of over 600,000 articles when its five-year transition to full Open Access is complete (January 2026 target date).
"They are right..." the site's editor-in-chief told Slashdot. "We need to get Google to reindex the new site ASAP."

According to a new study, almost half of America's new college graduates are winding up in jobs they didn't need to go to college to get. CBS News reports: If a graduate's first job is in a low-paying field or out-of-line with a worker's interests, it could pigeonhole them into an undesirable role or industry that's hard to escape, according to a new study (PDF) from The Burning Glass Institute and the Strada Institute for the Future of Work. Another study from the HEA Group found that a decade after enrolling in college, attendees of 1 in 4 higher education programs are earning less than $32,000 -- the median annual income for high school graduates. A college degree, in itself, is not a ticket to a higher-paying job, the study shows.

"Getting a college degree is viewed as the ticket to the American dream," said [Burning Glass CEO Matt Sigelman], "and it turns out that it's a bust for half of students." The single greatest determinant of post-graduation employment prospects, according to the study, is a college student's major, or primary focus of study. It can be even more important than the type of institution one attends. Choosing a career-oriented major like nursing, as opposed to criminal justice, gives graduates a better shot at actually using, and getting compensated for the skills they acquire. Just 23% of nursing students are underemployed, versus 68% of criminal justice majors. However, focusing on science, technology, engineering and mathematics (STEM) subjects is not a guarantee of college-level employment and high wages, the study found. [...]

Many college graduates remain underemployed even 10 years after college, the study found. That may be because employers seeking college-level skills also tend to focus on job candidates' recent work experience, placing more emphasis on the latest jobs held by candidates who have spent years in the workforce, versus a degree that was earned a decade prior. "If you come out of school and work for a couple of years as waiter in a restaurant and apply for a college-level job, the employer will look at that work experience and not see relevance," Sigelman said.

Dr. Ruth Gottesman, a longtime professor at the Albert Einstein College of Medicine, is making free tuition available to all students going forward. From a report: The 93-year-old widow of a Wall Street financier has donated $1 billion to a Bronx medical school, the Albert Einstein College of Medicine, with instructions that the gift be used to cover tuition for all students going forward. The donor, Dr. Ruth Gottesman, is a former professor at Einstein, where she studied learning disabilities, developed a screening test and ran literacy programs. It is one of the largest charitable donations to an educational institution in the United States and most likely the largest to a medical school.

The fortune came from her late husband, David Gottesman, known as Sandy, who was a protege of Warren Buffett and had made an early investment in Berkshire Hathaway, the conglomerate Mr. Buffett built. The donation is notable not only for its staggering size, but also because it is going to a medical institution in the Bronx, the city's poorest borough. The Bronx has a high rate of premature deaths and ranks as the unhealthiest county in New York. Over the past generation, a number of billionaires have given hundreds of millions of dollars to better-known medical schools and hospitals in Manhattan, the city's wealthiest borough.

While her husband ran an investment firm, First Manhattan, Dr. Gottesman had a long career at Einstein, a well-regarded medical school, starting in 1968, when she took a job as director of psychoeducational services. She has long been on Einstein's board of trustees and is currently the chair. In recent years, she has become close friends with Dr. Philip Ozuah, the pediatrician who oversees the medical college and its affiliated hospital, Montefiore Medical Center, as the chief executive officer of the health system. That friendship and trust loomed large as she contemplated what to do with the money her husband had left her.

theodp writes: Asked at the recent World Government Summit in Dubai what people should focus on when it comes to education, what should they learn, and how they should educate their kids and their societies, Nvidia CEO Jensen Huang made a counterintuitive break from tech CEOs advising youngsters to learn how to code. Huang argued that, even at this early stage of the AI revolution, programming is no longer a vital skill. With coding taken care of by AI, Huang suggested humans can instead focus on more valuable expertise like biology, education, manufacturing, or farming

From the video: "You probably recall over the course of the last 10 years, 15 years, almost everybody who sits on a stage like this would tell you it is vital that your children learn computer science, everybody should learn how to program, and in fact it's almost exactly the opposite. It is our job to create computing technology such that nobody has to program and that the programming language, it's human, everybody in the world is now a programmer. This is the miracle, this is the miracle of artificial intelligence. For the very first time, we have closed the gap, the technology divide has been completely closed and it's the reason why so many people can engage artificial intelligence. It is the reason why every single government, every single industrial conference, every single company is talking about artificial intelligence today. Because for the very first time you can imagine everybody in your company being a technologist.

"And so, this is a tremendous time for all of you to realize that the technology divide has been closed. Or another way to say it, the technology leadership of other countries has now been reset. The countries, the people that understand how to solve a domain problem in digital biology, or in education of young people, or in manufacturing or in farming, those people who understand domain expertise now can utilize technology that is readily available to you. You now have a computer that will do what you tell it to do to help automate your work, to amplify your productivity, to make you more efficient. And so, I think that this is just a tremendous time. The impact of course is great and your imperative to activate and take advantage of the technology is absolutely immediate. And also to realize that to engage AI is a lot easier now than at any time in the history of computing. It is vital that we upskill everyone and the upskilling process, I believe, will be delightful, surprising, to realize that this computer can perform all these things that you're instructing it to do and doing it so easily."

Huang's words come as tech-backed nonprofit Code.org-- which is lobbying to make CS a high school graduation requirement in all 50 states -- hedges its bets by also including AI usage as part of its mission through its new TeachAI initiative (trademark pending). Interestingly, conspicuous by its absence from the Who's Who of tech giants on the advisory committee for the Code.org staffed-and-operated TeachAI is Nvidia (Nvidia is also missing from the list of Code.org donors). So, is it time to revisit the question of Is AI an Excuse for Not Learning To Code?

Since 2010, billionaire tech investor Peter Thiel has offered to pay about 20 students $100,000 to drop out of school each year "to start companies or nonprofits," reports the Wall Street Journal. His program has now backed 271 people, and this year the applicant pool "is bigger than ever."

So how's it going? Some big successes include Vitalik Buterin, co-founder of Ethereum, the blockchain network; Laura Deming, a key figure in venture investing in aging and longevity; Austin Russell, who runs self-driving technologies company Luminar Technologies; and Paul Gu, co-founder of consumer lending company Upstart...

Thiel and executives of the fellowship acknowledge they have learned painful lessons along the way. Some applicants pursued ambitious ideas that turned out to be unrealistic, for example. "Asteroid mining is great for press releases but maybe we should have pushed back early on," he says. Others were better at applying to be Thiel fellows than they were starting businesses, it turned out... They've also learned that lone geniuses with brilliant ideas aren't usually the kinds of people who can build organizations. "It's a team sport to get something going and build on it, you can't just be a mad genius, you have to have some social skills and emotional intelligence," says Michael Gibson, an early leader of the organization who is co-founder of a venture fund that invests primarily in those who don't have a college degree...

Thiel hasn't attempted to build a better education system, which program officials acknowledge has made it harder to develop talent in the program... Thiel fellows say they don't receive much more than funding from the program and have limited contact with Thiel, though access to a network of former Thiel fellows can be useful. "Meeting some of the other members inspires you to think bigger," says Boyan Slat, a 2016 Thiel fellow who is chief executive of The Ocean Cleanup, a Netherlands-based nonprofit developing technologies to remove plastic from oceans. Slat says he has spoken to Thiel "three or four times."

As a result, Thiel and other staffers have concluded they can't grow beyond the 20 or so young people chosen as fellows each year. "If you scale the program," Thiel says, "you will have a lot more people who aren't quite ready, you would then have to be super-confident you can develop them" — which Thiel and his colleagues say they aren't skilled at doing... About a quarter of the Thiel fellows eventually returned to college to finish their degrees, suggesting that even the dropouts see enduring value in higher education.

Thiel says they "got way more out of it by going back" after launching their businesses.

"The other 75% didn't need a college degree," he says.

Long-time Slashdot reader theodp writes: In 2012, Microsoft President Brad Smith unveiled Microsoft's National Talent Strategy, which called for K-12 Computer Science education for U.S. schoolchildren to address a "talent crisis [that] endangers long-term growth and prosperity". The following year, tech-backed nonprofit Code.org burst onto the scene to deliver that education to schoolchildren, with Smith and execs from tech giants Google and Amazon on its Board of Directors (and Code.org donors Bill Gates and Mark Zuckerberg as lead K-12 CS instructors).

Using a mix of paid individuals, universities and other organizations that it helped to fund, along with online self-paced courses, Code.org boasts it quickly "prepared more than 106,000 new teachers to teach CS across grades K-12" through its professional learning programs. "No computer science experience required," Code.org teases prospective K-12 teachers (as does Code.org partner Amazon Future Engineer). Code.org organized K-12 CS teacher workforce expansion workshops.

However, at least one state is taking steps to put an end to the practice of rebranding individuals as K-12 CS teachers in as little as a day, albeit with a generous 10-year loophole for currently uncertified K-12 CS teachers. "At the start of the 2024-2025 academic year," reports GovTech, "the New York State Education Department (NYSED) is honing its credential requirements for computer science teachers, though the state has yet to join the growing list of those mandating computer science instruction for high school graduation. According to the department's website, as of Sept. 1, 2024, educators who teach computer science will need either a Computer Science Certificate issued by the state Board of Regents or a Computer Science Statement of Continued Eligibility (SOCE), which may be given to instructors who don't have the specific certificate but have nonetheless taught computer science since Sept. 1, 2017....

"The NYSED website says the SOCE is a temporary measure that will be phased out after 10 years, at which point all computer science instructors will need a Computer Science Certificate."

JSTOR: At the end of 2023, JSTOR -- a vast digital library of secondary and primary sources to support teaching and learning -- reached a once unimaginable goal: providing JSTOR access in 1,000 prisons. Spread across four continents, the JSTOR Access in Prison initiative now supports the education and growth of more than 550,000 incarcerated people.

Incarcerated learners have been left behind for decades. Limited access to the internet and scarce funding and support for higher education in prisons made access to digital libraries like JSTOR all but impossible. In October 2021, with funding from the Mellon Foundation, JSTOR set an ambitious goal to change that. The aspiration? For every incarcerated college student in the United States to have access to JSTOR, along with the research skills to use it and other digital resources.

Prior to 2021, JSTOR developed an offline index of its digital library. At the time, less than twenty prisons had access to it. Since then, developers have created an online version that meets the unique needs of carceral settings, most recently delivering online access on tablets. These changes -- and the leadership of Stacy Burnett, a graduate of the Bard Prison Initiative who was hired to lead the JSTOR Access in Prison initiative -- have enabled 1,000 prisons and more than 500,000 people to gain access to the digital equivalent of a college library.

Stephanie Saul reports via the New York Times: Yale University will require standardized test scores for admission for students applying to enter for the class entering in the fall of 2025, becoming the second Ivy League university to abandon test-optional policies that had been widely embraced during the Covid pandemic. Yale officials said in an announcement on Thursday that the shift to test-optional policies might have unwittingly harmed students from lower-income families whose test scores could have helped their chances. While it will require standardized tests, Yale said its policy would be "test flexible," permitting students to submit scores from subject-based Advanced Placement or International Baccalaureate tests in lieu of SAT or ACT scores. The decision follows a similar decision in February from Dartmouth College. MIT also announced that it had reinstated its testing requirement in 2022.

Academics have found that the U.S. mortality declines during recessions, with "reductions in air pollution... a quantitatively important mechanism." Abstract of a paper on National Bureau of Economic Research: We leverage spatial variation in the severity of the Great Recession across the United States to examine its impact on mortality and to explore implications for the welfare consequences of recessions. We estimate that an increase in the unemployment rate of the magnitude of the Great Recession reduces the average, annual age-adjusted mortality rate by 2.3 percent, with effects persisting for at least 10 years. Mortality reductions appear across causes of death and are concentrated in the half of the population with a high school degree or less. We estimate similar percentage reductions in mortality at all ages, with declines in elderly mortality thus responsible for about three-quarters of the total mortality reduction. Recession-induced mortality declines are driven primarily by external effects of reduced aggregate economic activity on mortality, and recession-induced reductions in air pollution appear to be a quantitatively important mechanism. Incorporating our estimates of pro-cyclical mortality into a standard macroeconomics framework substantially reduces the welfare costs of recessions, particularly for people with less education, and at older ages where they may even be welfare-improving.

"We're currently witnessing a rapid expansion in the abuse of these new AI tools by bad actors," writes Microsoft VP Brad Smith, "including through deepfakes based on AI-generated video, audio, and images.

"This trend poses new threats for elections, financial fraud, harassment through nonconsensual pornography, and the next generation of cyber bullying." Microsoft found its own tools being used in a recently-publicized episode, and the VP writes that "We need to act with urgency to combat all these problems."

Microsoft's blog post says they're "committed as a company to a robust and comprehensive approach," citing six different areas of focus:

• A strong safety architecture. This includes "ongoing red team analysis, preemptive classifiers, the blocking of abusive prompts, automated testing, and rapid bans of users who abuse the system... based on strong and broad-based data analysis."

• Durable media provenance and watermarking. ("Last year at our Build 2023 conference, we announced media provenance capabilities that use cryptographic methods to mark and sign AI-generated content with metadata about its source and history.")

• Safeguarding our services from abusive content and conduct. ("We are committed to identifying and removing deceptive and abusive content" hosted on services including LinkedIn and Microsoft's Gaming network.)

• Robust collaboration across industry and with governments and civil society. This includes "others in the tech sector" and "proactive efforts" with both civil society groups and "appropriate collaboration with governments."

• Modernized legislation to protect people from the abuse of technology. "We look forward to contributing ideas and supporting new initiatives by governments around the world."

• Public awareness and education. "We need to help people learn how to spot the differences between legitimate and fake content, including with watermarking. This will require new public education tools and programs, including in close collaboration with civil society and leaders across society."

After a 6-1 vote by the district board, San Francisco middle schools will teach Algebra I again this fall. Axios reports: Roughly a third of SFUSD middle schools this fall will begin offering the course to eighth graders at about a third of its 13 middle schools as well as six of its K-8 schools, the San Francisco Chronicle reports. Students at other campuses will have access to the course via online classes or summer school while their schools take three years to make the transition. Those eighth graders will otherwise have to wait until high school to take the course.

District officials plan to evaluate the best way to enroll students throughout the district in a pilot at the first schools this fall. The first approach would be to enroll all eighth graders. The second would prioritize students' interest or readiness. The third would give students the option of taking Algebra I on top of current eighth-grade math curricula.

The 6-1 vote by the San Francisco Unified School District board Tuesday followed a decadelong battle over eighth graders' access to higher-level math courses and a larger debate over academic opportunity and equity in math performance. SFUSD previously taught eighth-grade algebra. But in 2014, the board voted to wait until high school to try to address racial gaps that had emerged as some students moved quicker to advanced math classes. Studies have shown that inequities including socioeconomic status, language differences and implicit bias often impede Black and Latino students' educational pursuits and result in lower rates of enrollment in higher-level classes. Yes, but: Stanford researchers found last year that large racial and ethnic gaps in advanced math enrollment persisted even after the policy change.

New York City's public schools chancellor said the city did not pass Tuesday's remote learning "test" due to technical issues. From a report: "As I said, this was a test. I don't think that we passed this test," David Banks said during a news briefing, adding that he felt "disappointed, frustrated and angry" as a result of the technical issues. NYC Public Schools did a lot of work to prepare for the remote learning day, Banks said, but shortly before 8 a.m. they were notified that parents and students were having difficulty signing onto remote learning.

This is the first time NYC Public Schools has implemented remote learning on a snow day since introducing the no snow day policy in 2022. The district serves 1.1 million students in more than 1,800 schools. Banks blamed the technical issues on IBM, which helps facilitate the city's remote learning program. "IBM was not ready for primetime," Banks said, adding that the company was overwhelmed with the surge of people signing on for school. IBM has since expanded their capacity and a total of 850,000 students and teachers are currently online, Banks said. "We'll work harder to do better next time," he said, adding that there will be a deeper analysis into what went wrong.

Researchers have made significant progress toward developing a blood test that can predict the risk of dementia up to 15 years before clinical diagnosis. The Guardian reports: Hopes for the test were raised after scientists discovered biological markers for the condition in blood samples collected from more than 50,000 healthy volunteers enrolled in the UK Biobank project. Analysis of the blood identified patterns of four proteins that predicted the onset of dementia in general, and Alzheimer's disease and vascular dementia specifically, in older age. When combined with more conventional risk factors such as age, sex, education and genetic susceptibility, the protein profiles allowed researchers to predict dementia with an estimated 90% accuracy nearly 15 years before people received clinical confirmation of the disease.

For the latest study, blood samples from 52,645 UK adults without dementia were collected and frozen between 2006 and 2010 and analyzed 10 to 15 years later. More than 1,400 participants went on to develop dementia. Using artificial intelligence, the researchers looked for connections between nearly 1,500 blood proteins and developing dementia years later. Writing in Nature Aging, they describe how four proteins, Gfap, Nefl, Gdf15 and Ltbp2, were present in unusual levels among those who developed all-cause dementia, Alzheimer's disease or vascular dementia. Higher levels of the proteins were warning signs of disease. Inflammation in the brain can trigger cells called astrocytes to over-produce Gfap, a known biomarker for Alzheimer's. People with raised Gfap were more than twice as likely to develop dementia than those with lower levels.

Another blood protein, Nefl, is linked to nerve fibre damage, while higher than normal Gdf15 can occur after damage to the brain's blood vessels. Rising levels of Gfap and Ltbp2 was highly specific for dementia rather than other brain diseases, the scientists found, with changes occurring at least 10 years before people received a dementia diagnosis. The researchers are speaking to companies to develop the test but said the cost, currently at several hundred pounds, would need to come down to make it viable.

Abstract of a paper [PDF] the on pre-print server Arxiv: Citations are widely considered in scientists' evaluation. As such, scientists may be incentivized to inflate their citation counts. While previous literature has examined self-citations and citation cartels, it remains unclear whether scientists can purchase citations. Here, we compile a dataset of about 1.6 million profiles on Google Scholar to examine instances of citation fraud on the platform. We survey faculty at highly-ranked universities, and confirm that Google Scholar is widely used when evaluating scientists. Intrigued by a citationboosting service that we unravelled during our investigation, we contacted the service while undercover as a fictional author, and managed to purchase 50 citations. These findings provide conclusive evidence that citations can be bought in bulk, and highlight the need to look beyond citation counts.
