Researchers say infrasound -- low-frequency vibrations from things like pipes, HVAC systems, and traffic that humans can't consciously hear -- may help explain why some old buildings feel unsettling or "haunted." Rodney Schmaltz, senior author and professor at MacEwan, says: "Consider visiting a supposedly haunted building. Your mood shifts, you feel agitated, but you can't see or hear anything unusual. In an old building, there is a good chance that infrasound is present, particularly in basements where aging pipes and ventilation systems produce low-frequency vibrations. If you were told the building was haunted, you might attribute that agitation to something supernatural. In reality, you may simply have been exposed to infrasound." ScienceBlog.com reports: Infrasound sits below roughly 20 Hz, the lower limit of what the human ear can ordinarily detect. It's generated by storms, by volcanic activity, by tectonic rumblings deep in the Earth's crust, and (this is the part that matters) by the mundane mechanical heartbeat of cities: ageing pipes, HVAC systems, traffic, industrial machinery. "Infrasound is pervasive in everyday environments, appearing near ventilation systems, traffic, and industrial machinery," says Schmaltz. Most of the time, we walk through it without a second thought. The question the team wanted to answer was whether walking through it was actually doing something to us, whether the frequency was registered somewhere below consciousness, somewhere we couldn't readily name.

The experimental setup was deliberately ordinary. Thirty-six undergraduate students filed one at a time into isolated testing rooms and sat alone with a piece of music, either a calming instrumental or a horror-themed ambient track designed to provoke discomfort. Hidden subwoofers, including a 12-inch unit positioned in an adjacent hallway and a 16-inch speaker oriented toward the ceiling in a neighboring room, pumped infrasound at approximately 18 Hz into half those spaces. The participants had no idea. That last point turned out to be rather important. When the team ran the numbers, they found that participants couldn't reliably identify whether infrasound had been present. Their guesses were, statistically speaking, no better than chance. And according to Schmaltz, participants' beliefs about whether the infrasound was on had no detectable effect on their cortisol or mood. The physiological response didn't care what the participants thought was happening. It just happened anyway.

What happened, specifically, was this: those exposed to infrasound reported higher irritability, lower interest in the music, and a tendency to rate the music as sadder, irrespective of whether it was the calming or the horror track. Cortisol levels, measured before and about 20 minutes after exposure, were also elevated. Kale Scatterty, the PhD student who led the work, notes that irritability and cortisol do tend to move together under ordinary stress, but adds that "infrasound exposure had effects on both outcomes that went beyond that natural relationship." That distinction matters more than it might seem. Previous theories about infrasound and paranormal experience have often leaned on anxiety as the explanatory mechanism, the idea that low-frequency sound triggers a kind of free-floating dread that the mind then reaches for supernatural explanations to account for. The new data don't really support that picture. Measures of anxiety didn't budge significantly. What went up was irritability and disinterest, a kind of sour, low-grade aversion rather than fear. That's perhaps a more honest description of how a lot of ghost stories actually feel in the telling: not screaming terror, but wrong atmosphere, a sense of unease that never quite crystallizes into something you can point at. The study has been published this week in Frontiers in Behavioral Neuroscience.

OpenAI has launched Prism, a free scientific research app that aims to do for scientific writing what coding agents did for programming. Engadget reports: Prism builds on Crixet, a cloud-based LaTeX platform the company is announcing it acquired today. For the uninitiated, LaTeX is a typesetting system for formatting scientific documents and journals. Nearly the entire scientific community relies on LaTeX, but it can make some tasks, such as drawing diagrams through TikZ commands, time-consuming to do. Beyond that, LaTeX is just one of the software tools a scientist might turn to when preparing to publish their research.

That's where Prism comes into the picture. Like Crixet before it, the app offers robust LaTeX editing and a built-in AI assistant. Where previously it was Crixet's own Chirp agent, now it's GPT-5.2 Thinking. OpenAI's model can help with more than just formatting journals -- in a press demo, an OpenAI employee used it to find and incorporate scientific literature that was relevant to the paper they were working on, with GPT-5.2 automating the process of writing the bibliography. [...] Later in the same demo, the OpenAI employee used Prism to generate a lesson plan for a graduate course on general relativity, as well as a set of problems for students to solve. OpenAI envisions these features helping scientists and professors spend less time on the more tedious tasks in their professions.

According to Bloomberg, several major Chinese AI companies, including Alibaba, ByteDance, and Tencent, have temporarily disabled certain chatbot features during the gaokao college entrance exams to prevent cheating. "Popular AI apps, including Alibaba's Qwen and ByteDance's Doubao, have stopped picture recognition features from responding to questions about test papers, while Tencent's Yuanbao, Moonshot's Kimi have suspended photo-recognition services entirely during exam hours," adds The Verge. From the report: The rigorous multi-day "gaokao" exams are sat by more than 13.3 million Chinese students between June 7-10th, each fighting to secure one of the limited spots at universities across the country. Students are already banned from using devices like phones and laptops during the hours-long tests, so the disabling of AI chatbots serves as an additional safety net to prevent cheating during exam season.

When asked to explain the suspension, Bloomberg reports the Yuanbao and Kimi chatbots responded that functions had been disabled "to ensure the fairness of the college entrance examinations." Similarly, the DeepSeek AI tool that went viral earlier this year is also blocking its service during specific hours "to ensure fairness in the college entrance examination,"according to The Guardian. The Guardian notes that the news is being driven by students on the Chinese social media platform Weibo. "The gaokao entrance exam incites fierce competition as it's the only means to secure a college placement in China, driving concerns that students may try to improve their chances with AI tools," notes The Verge.

An anonymous reader quotes a report from TechCrunch: In a world filled with "vibe coding," Zach Yadegari, teen founder of Cal AI, stands in ironic, old-fashioned contrast. Ironic because Yadegari and his co-founder, Henry Langmack, are both just 18 years old and still in high school. Yet their story, so far, is a classic. Launched in May, Cal AI has generated over 5 million downloads in eight months, Yadegari says. Better still, he tells TechCrunch that the customer retention rate is over 30% and that the app generated over $2 million in revenue last month. [...]

The concept is simple: Take a picture of the food you are about to consume, and let the app log calories and macros for you. It's not a unique idea. For instance, the big dog in calorie counting, MyFitnessPal, has its Meal Scan feature. Then there are apps like SnapCalorie, which was released in 2023 and created by the founder of Google Lens. Cal AI's advantage, perhaps, is that it was built wholly in the age of large image models. It uses models from Anthropic and OpenAI and RAG to improve accuracy and is trained on open source food calorie and image databases from sites like GitHub.

"We have found that different models are better with different foods," Yadegari tells TechCrunch. Along the way, the founders coded through technical problems like recognizing ingredients from food packages or in jumbled bowls. The result is an app that the creators say is 90% accurate, which appears to be good enough for many dieters. The report says Yadegari began mastering Python and C# in middle school and went on to build his first business in ninth grade -- a website called Totally Science that gave students access to unblocked games (cleverly named to evade school filters). He sold the company at age 16 to FreezeNova for $100,000.

Following the sale, Yadegari immersed himself in the startup scene, watching Y Combinator videos and networking on X, where he met co-founder Blake Anderson, known for creating ChatGPT-powered apps like RizzGPT. Together, they launched Cal AI and moved to a hacker house in San Francisco to develop their prototype.

"Students should not have to fear expulsion for expressing themselves on social media after school and off-campus, but that is just what happened to the plaintiff in C1.G v. Siegfried," writes Mukund Rathi via the Electronic Frontier Foundation (DFF). "Last month, the Tenth Circuit Court of Appeals ruled the student's expulsion violated his First Amendment rights. The court's opinion affirms what we argued in an amicus brief last year." From the report: We strongly support the Tenth Circuit's holding that schools cannot regulate how students use social media off campus, even to spread "offensive, controversial speech," unless they target members of the school community with "vulgar or abusive language."

The case arose when the student and his friends visited a thrift shop on a Friday night. There, they posted a picture on Snapchat with an offensive joke about violence against Jews. He deleted the post and shared an apology just a few hours later, but the school suspended and eventually expelled him. [...] The Tenth Circuit held the First Amendment protected the student's speech because "it does not constitute a true threat, fighting words, or obscenity." The "post did not include weapons, specific threats, or speech directed toward the school or its students." While the post spread widely and the school principal received emails about it, the court correctly held that this did not amount to "a reasonable forecast of substantial disruption" that would allow regulation of protected speech.

More adolescents failed to quit smoking in 2020 than in any of the previous 13 years, according to new data published in the Journal of the American Medical Association. 2020 was the first year the research team had data on attempts to quit e-cigarettes, and it showed that around 4 percent of adolescents unsuccessfully attempted to quit e-cigarettes. From a report: E-cigarettes have been pushed to adult smokers as an alternative to traditional, combustible cigarettes -- some evidence shows they might be less dangerous, and there's mixed evidence that they could push adults to quit smoking altogether. But the picture might be different for teens, who started vaping in droves in 2018 and are far less likely to be cigarette smokers first. The new analysis shows that for younger people, the introduction of e-cigarettes made quitting more difficult.

The new study includes data from the Monitoring the Future study, which surveys eighth, 10th, and 12th grade students. It includes a question asking the participants if they had ever tried to stop smoking and found that they could not. In 2020, it added a question asking if they'd ever tried to stop vaping nicotine and found that they could not. From 1997 to 2019, the survey found that the number of students who reported using cigarettes and the percent of adolescents estimated to have tried and failed to quit smoking both dropped.

NGOs looking to provide emergency aid to Afghanistan are turning to cryptocurrency. From a report: When the Taliban took over Afghanistan in August of last year, Fereshteh Forough feared that the group would close her school in Herat, the country's third-largest city. Code to Inspire, an NGO Forough founded, was teaching computer programming to young Afghan women, and the Taliban oppose secondary education for women. Months later, the picture is much different -- and worse -- from what Forough imagined. The school survived, becoming mostly virtual, but has transformed from a coding boot camp into a relief organization. The biggest risk for Forough's students wasn't lack of education, it was hunger. Forough looked for a way to provide emergency checks to the women but was stymied by banks that don't want to risk violating severe U.S. sanctions.

JPMorgan Chase repeatedly blocked her attempts to transfer money, she said, and she grew increasingly alarmed by students who said they couldn't access cash at local Afghan banks -- many of which have closed or imposed strict withdrawal limits. In response, she turned to cryptocurrency to provide monthly emergency payments to help students afford enough food to survive. [...] There are several advantages to using crypto: Afghans fleeing the Taliban can take their assets with them without risk. Humanitarian agencies seeking to bypass banks and discreetly avoid the Taliban can provide cash directly to those in need. Smugglers and intermediaries who may steal or try to resell aid packages can be circumvented if aid is given directly through a digital transaction.

IEEE Spectrum's August issue will include an article titled "The Top Programming Languages."

Calculated using metrics from 11 online sources, it concludes that "One thing remains constant: the dominance of Python." Our default ranking is weighted toward the interests of an IEEE member, and looking at the top entries, we see that Python has held onto its comfortable lead, with Java and C once again coming in second and third place, respectively. Arduino has seen a big jump, rising from 11th place to seventh. (Purists may argue that Arduino is not a language but rather a hardware platform that is programmed using a derivative of Wiring, which itself is derived from C/C++. But we have always taken a very pragmatic approach to our definition of "programming language," and the reality is that when people are looking to use an Arduino-compatible microcontroller, they typically search for "Arduino code" or buy books about "Arduino programming," not "Wiring code" or "C programming.")

One interpretation of Python's high ranking is that its metrics are inflated by its increasing use as a teaching language: Students are simply asking and searching for the answers to the same elementary questions over and over. There's an historical parallel here. In the 1980s, BASIC was very visible... But few professional programmers used it, and when the home computer bubble burst, so did BASIC's, although some advanced descendants like Microsoft Visual Basic are still relatively popular professionally.

There are two counterarguments, though: The first is that students are people, too! If we pay attention only to what professional and expert coders do, we're at risk of missing an important part of the picture. The second is that, unlike BASIC, Python is frequently used professionally and in high-profile realms, such as machine learning, thanks to its enormous collection of high quality, specialized libraries.
C++ came in fourth, followed by JavaScript, R, "Arduino," Go, Swift, and Matlab.

But because different programmers have different needs, they've also created a special interactive version of their rankings online, "allowing you to weight the metrics as you see fit... "

"High school students who took Advanced Placement exams online this week may have to do it again next month because of a technical glitch," writes CNN, sharing some of the students' horror stories. With 45 seconds left in her exam, 11th-grader Maggie McLauchlin of Jacksonville, Florida, took a video of what appears to be a black screen as she tried to upload her exam answers as instructed by The College Board. "I'm trying to take the picture but there's just black and I only have 45 seconds left," Maggie says tearfully. "It's not working..."

Jamye Smith is an AP US History teacher at Fort Zumwalt North High School in O'Fallon, Missouri. She told CNN 27 of her students signed up to take the test. So far she's heard from three students who were unable to submit their exams due to a variety of errors, none of which they caused, she said. Smith said her colleagues teaching other subjects also said their students struggled to do the same.
Because of time zone differences, one American student in Japan had to take his four tests at 3 a.m. and 5 a.m. — only to discover that two of them weren't submitted, CNN reports.

"Unfortunately, there isn't another way to submit," the College Board admitted on Twitter, saying they believed the primary cause was outdated web browsers. They told CNN Friday that "After the first few days of testing, our data show the vast majority of students successfully completed their exams, with less than 1 percent [of 1.64 million students] unable to submit their responses..."

"We share the deep disappointment of students who were unable to complete their exam — whether for technical issues or other reasons."

Corporations love to pretend that 'anonymization' of the data they collect protects consumers. Studies keep showing that's not really true. From a report: Last fall, AdBlock Plus creator Wladimir Palant revealed that Avast was using its popular antivirus software to collect and sell user data. While the effort was eventually shuttered, Avast CEO Ondrej Vlcek first downplayed the scandal, assuring the public the collected data had been "anonymized" -- or stripped of any obvious identifiers like names or phone numbers. "We absolutely do not allow any advertisers or any third party...to get any access through Avast or any data that would allow the third party to target that specific individual," Vlcek said. But analysis from students at Harvard University shows that anonymization isn't the magic bullet companies like to pretend it is.

Dasha Metropolitansky and Kian Attari, two students at the Harvard John A. Paulson School of Engineering and Applied Sciences, recently built a tool that combs through vast troves of consumer datasets exposed from breaches for a class paper they've yet to publish. "The program takes in a list of personally identifiable information, such as a list of emails or usernames, and searches across the leaks for all the credential data it can find for each person," Attari said in a press release. They told Motherboard their tool analyzed thousands of datasets from data scandals ranging from the 2015 hack of Experian, to the hacks and breaches that have plagued services from MyHeritage to porn websites. Despite many of these datasets containing "anonymized" data, the students say that identifying actual users wasn't all that difficult. "An individual leak is like a puzzle piece," Harvard researcher Dasha Metropolitansky told Motherboard. "On its own, it isn't particularly powerful, but when multiple leaks are brought together, they form a surprisingly clear picture of our identities. People may move on from these leaks, but hackers have long memories."

An anonymous reader quotes a report from NPR: In a move that puts California on a collision course with the NCAA, Gov. Gavin Newsom has signed a bill effectively allowing college athletes in the state to earn compensation for the use of their likeness, sign endorsement deals and hire agents to represent them. The governor signed the measure in a segment released Monday by Uninterrupted, a sports programming company co-founded by LeBron James. Newsom proclaimed the move as "the beginning of a national movement -- one that transcends geographic and partisan lines."

California is the first state to pass such a law, which is to take effect on Jan. 1, 2023. That marks a significant shift from the current policies enforced by the NCAA, collegiate sports' national governing body, which generally renders student-athletes ineligible to accept compensation for "the use of his or her name or picture to advertise, recommend or promote directly the sale or use of a commercial product or service of any kind." And the NCAA Board of Governors pushed back hard against the bill at the time of its passage in the Legislature, saying that it would leave the playing field for universities of different sizes radically uneven. "Collegiate student athletes put everything on the line -- their physical health, future career prospects and years of their lives to compete. Colleges reap billions from these student athletes' sacrifices and success but, in the same breath, block them from earning a single dollar," Newsom said in a statement. "That's a bankrupt model -- one that puts institutions ahead of the students they are supposed to serve. It needs to be disrupted."

In response, a 22-member panel composed mostly of university presidents and athletic directors said in a letter: "Right now, nearly half a million student-athletes in all 50 states compete under the same rules. This bill would remove that essential element of fairness and equal treatment that forms the bedrock of college sports."

The College Board is abandoning its plan to assign an adversity score to every student who takes the SAT college admissions test, after facing criticism from educators and parents. Instead, it will try to capture a student's social and economic background in a broad array of data points (Warning: source paywalled, alternative source). The new tactic is called Landscape and doesn't combine the metrics into a single score. The Wall Street Journal reports: The original tool, called the "environmental context dashboard," combined about 15 socio-economic metrics from a student's high school and neighborhood to create something college admission officers called an "adversity score." Landscape is designed to help colleges compare an applicant's test scores to other students in their high school and beyond, the College Board said. It also aims to give a picture of the quality of the school and relative wealth and stability of the neighborhood.

Six "challenge factors" provide the "summary neighborhood challenge indicator" and the "summary high school challenge indicator," according to the College Board. The six factors are college attendance, household structure, median family income, housing stability, education levels and crime. Colleges have long considered students' high schools and neighborhoods when making admissions decisions, but with more applications coming from more places, incorporating consistent information about every high school and neighborhood becomes difficult, according to college admissions officers. Colleges will receive more than 10 million applications form students attending more than 30,000 high schools. Admissions officers who tested Landscape estimate they lack high school information for about 25% of all applications, the College Board said.

A post this week on Microsoft's developer blog explains "what we, the Python team, have done to make Python easier to install on Windows" after the next update.

TLDR: Typing 'python' in Windows' Command Prompt will take you to the Microsoft Store's Python page: Microsoft has been involved with the Python community for over twelve years, and currently employ four of the key contributors to the language and primary runtime. The growth of Python has been incredible, as it finds homes among data scientists, web developers, system administrators, and students, and roughly half of this work is already happening on Windows. And yet, Python developers on Windows find themselves facing more friction than on other platforms. It's been widely known for many years that Windows is the only mainstream operating system that does not include a Python interpreter out of the box... So we made things easier.

First, we helped the community release their distribution of Python to the Microsoft Store. This version of Python is fully maintained by the community, installs easily on Windows 10, and automatically makes common commands such as python, pip and idle available (as well as equivalents with version numbers python3 and python3.7, for all the commands, just like on Linux). Finally, with the May 2019 Windows Update, we are completing the picture. While Python continues to remain completely independent from the operating system, every install of Windows will include python and python3 commands that take you directly to the Python store page. We believe that the Microsoft Store package is perfect for users starting out with Python, and given our experience with and participation in the Python community we are pleased to endorse it as the default choice.
And while this fix is only for Python, the Microsoft post adds that "Over time, we plan to extend similar integration to other developer tools and reduce the getting started friction."

New advances are taking automation to the highest end of human endeavors, offering scientists a shot at some of the most intractable problems that have confounded them -- and along the way tipping a global balance to give upstarts like China a more level playing field in the lab. From a report: A combination of artificial intelligence and nimble robots are allowing scientists to do more, and be faster, than they ever could with mere human hands and brains. "We're in the middle of a paradigm shift, a time when the choice of experiments and the execution of experiments are not really things that people do," says Bob Murphy, the head of the computational biology department at Carnegie Mellon University.

Automated science is "moving the role of the scientist higher and higher up the food chain," says Murphy. Researchers are focusing their efforts on big-picture problem-solving rather than the nitty-gritty of running experiments. He says it will also allow scientists to take on more problems at once -- and solve big, lingering ones that are too complex to tackle right now. Starting next year, Murphy's department will offer students a master's degree in automated science, the university announced last week.

When someone visits the buildings of Shawsheen Valley Technical High School in Billerica, as they walk through the secure foyer, they have to get their driver's license or another state-issued ID scanned. But the secure foyer does kind of a high-level national background check, too, explains Superintendent Tim Broadrick. From a report: The "LobbyGuard" scanner is the size of a computer tablet. It scans a driver's license, takes a picture of the school visitor and if all is OK with the person's background check, almost instantly clears the person to enter the school. An employee behind a window then pushes a button and unlocks the door to the school hallway. Amid nationwide concern about school shootings, there's talk at Shawsheen Tech of covering the wall of glass in the lobby with a special film to make it harder for a bullet to pierce. There's also a police officer -- known as a school resource officer -- stationed at the school. He has an office in the lobby. And the school has adopted another security measure to try to protect students from attacks -- one you can't see. It's a computer program designed to detect threats against the school in social media posts. And it runs 24/7.

"It's receiving and filtering and then gives us alerts when certain kinds of public communication are detected," Broadrick explains. Shawsheen Tech buys the social media scanning service from a Vermont-based company called Social Sentinel. It's one of many technology firms doing some form of social media scanning or monitoring. Social Sentinel claims it's the only one with expertise in protecting schools. Shawsheen Tech has about 1,300 students. It pays Social Sentinel approximately $10,000 per year, according to Broadrick.

An anonymous reader writes: An upcoming report by the Higher Education Commission, a UK group of MPs, business and academic professionals, will paint a picture of a higher education system that, thanks to the increasing use of data, may undergo radical change, sometimes with painful ethical considerations. Among their visions: an Amazon-style recommendation service on courses and work experience based on individuals' backgrounds, and similar profiles. Or a system in which students at risk of failure can be identified from their first day so that they receive instant feedback and performance measuring. It is envisioned that the system will include knowing whether they are in lectures, at the gym or in the bar, and in an effort to boost their results, students may also want to share data on their fitness, sleeping patterns, and their academic and semi-academic interactions online.

theodp writes: Microsoft has $92 billion in cash parked offshore, so it's kind of surprising to see a $722K National Science Foundation award is going towards validating the efficacy of Microsoft TEALS, the pet program of CEO Satya Nadella that sends volunteer software engineers with no teaching experience into high schools to teach kids and their teachers computer science. Among its Program Changes for 2015, TEALS said it "explicitly commits to provide a core set of curriculum materials that are complete, organized, and adaptable," which should help improve the outcome of the Developing Computer Science Pedagogical Content Knowledge through On-the-Job Learning NSF study schools are being asked to participate in. Meanwhile, CSTUY, a volunteer organization led by experienced CS teachers (including Slashdot user zamansky), finds itself turning to Kickstarter for $25K to fund Saturday Hacking Sessions. So, as Microsoft-backed Code.org — which has also attracted NSF award money to validate its CS program — is fond of saying: What's wrong with this picture? (To be fair to TEALS: it may have Microsoft backing, but it's not strictly a Microsoft effort, and also started out as a pure volunteer effort, as founder Kevin Wang explained earlier this year.)

Bruce66423 writes: A large scale European study shows that students who were unable to buy cannabis legally were 5% more likely to pass their University courses. Below-average students with no legal access to pot were 7.6% more likely to pass their courses, and the effect was five times more pronounced when dealing with courses involving math. One of the study's authors said, "We think this newfound effect on productivity from a change in legal access to cannabis is not negligible and should be, at least in the short run, politically relevant for any societal drug legalization and prohibition decision-making. In the bigger picture, our findings also indicate that soft drug consumption behavior is affected by their legal accessibility, which has not been causally demonstrated before. ... Considering the massive impact on cognitive performance high levels of THC have, I think it is reasonable to at least inform young users much more on consequences of consuming such products as compared with that of having a beer or pure vodka."

Bennett Haselton writes: They would never admit it, but your high school admins would probably breathe a sigh of relief if all of their sexting-mad students would go ahead and install Snapchat so that evidence of (sometimes) illegal sexting would disappear into the ether. They can't recommend that you do this, because it would sound like an implicit endorsement, just like they can't recommend designated drivers for teen drinking parties -- but it's a good bet they would be grateful. Read on for the rest.

Contributor Bennett Haselton writes with a interesting take on the recent release of racy celebrity photos: "Lawyers for Olympic gymnast McKayla Maroney succeeded in getting porn sites to take down her stolen nude photos, on the grounds that she was under 18 in the pictures, which meant they constituted child pornography. If true, that means that under current laws, Maroney could in theory be prosecuted for taking the original pictures. Maybe the laws should be changed?" Read on for the rest.
