  • Social Media Sites Got Information from Ad Trackers on US State Health Insurance Sites
    by EditorDavid on 09/05/2026 at 5:34 pm

    All 20 of America's state-run healthcare marketplace sites "include advertising trackers that share information with Big Tech companies," reports Gizmodo, citing a report from Bloomberg: Per the report, seven million Americans bought their health insurance through state exchanges in 2026, and many of them may have had personal information shared with companies, including Meta, TikTok, Snap, Google, Nextdoor, and LinkedIn, among others. Some of the data collected and shared with those companies included ZIP codes, a person's sex and citizenship status, and race. In addition to potentially sensitive biographical details about a person, the trackers also may reveal additional details about their life based on the sites they visit. For instance, Bloomberg found trackers on Medicaid-related web pages in Rhode Island, which could reveal information about a person's financial status and need for assistance. In Maryland, a Spanish-language page titled "Good News for Noncitizen Pregnant Marylanders" and a page designed to help DACA recipients navigate their healthcare options were found to be transmitting data to Big Tech firms... Per Bloomberg, several states have already removed some trackers from their exchange websites following the report. Thanks to Slashdot reader JoeyRox for sharing the news.

  • 10 People Called Police to Report Bigfoot Sighting in Ohio
    by EditorDavid on 09/05/2026 at 4:34 pm

    CNN reports on a "sudden surge of claimed sightings" of "unidentified figures averaging 8 feet tall in wooded areas" along Ohio's Mahoning River. "And it stopped just as quickly as it started," says Jeremiah Byron, host of the Bigfoot Society Podcast, which collected and mapped the reports .... Byron doesn't take every report at face value, making sure he talks to people directly before publicizing their claims. Once word got out about the reports in Ohio, so did the obvious fakes. "I started to get a lot of AI-generated reports in my email. It got up to the point where I was probably getting about 1,000 emails a day," he says. But when Byron spoke by phone with people who made the initial reports, they convinced him they weren't making anything up. "It was obvious they weren't just wanting to get their name out there," says Byron. "They were just freaked out by what they experienced, and they didn't want anything else to do with it." [...] Local law enforcement in Ohio also seem to be enjoying the publicity. Portage County Sheriff Bruce D. Zuchowski made a series of gag posts purporting to show the arrest of Bigfoot and his detention by Immigration and Customs Enforcement, only for the creature to escape from custody at the Canadian border... Despite the levity, the sheriff's office really did get some calls from concerned residents, Zuchowski says. "Ten individual people were like, 'Yeah I was walking my dog at 4 a.m. and I saw this hairy figure and I smelled this musty odor and there was this big thing and all of a sudden it ran,'" the sheriff told CNN affiliate WOIO in March.

  • Newspaper Chain's Reporters Withhold Their Bylines to Protest 'AI-Assisted' Articles
    by EditorDavid on 09/05/2026 at 3:34 pm

    A chain of 30 U.S. newspapers including the Sacramento Bee, the Miami Herald and the Idaho Statesman "has started to use a new AI tool that can summarize traditional articles and spit out different versions for different audiences," reports the New York Times. And the chain's reporters "are not happy about it." Journalists in many of the company's newsrooms are now withholding their bylines from articles created by the new tool, meaning that those articles will run with a generic credit rather than a reporter's name, as is customary. They are also labeled AI-assisted. "We don't want to put our bylines on stories we did not actually write even if they're based on our work," said Ariane Lange, an investigative reporter at the Sacramento Bee and the vice chair of the Sacramento Bee News Guild. "That in itself feels like a lie." The reporters' byline strike is one of the sharpest conflicts yet between journalists and their companies over the use of AI. Related debates are playing out in newsrooms across the country, as publishers experiment with new AI tools to streamline work that used to take hours, and some even use it to write full articles... [E]xecutives have promoted the tool internally as a way to increase the number of articles published and ultimately gain new subscribers... [Eric Nelson, the vice president of local news] said using reporters' bylines on the AI-generated articles was a way to show "authority" on Google so the search engine would rank the articles higher in the results. He also said the company was experimenting with feeding in reporters' notes to create articles. "Journalists who embrace and experiment with this tool are going to win," Nelson said in the meeting. "Journalists who are defiant will fall behind".... McClatchy's public AI policy states that the company uses AI tools to summarize articles to "help readers quickly understand the main points of a single story or catch up on multiple stories about a larger topic," and that editors review the output before publication.

  • Why Some US Schools Are Cutting Back On the Technology They Spent Billions On
    by EditorDavid on 09/05/2026 at 2:34 pm

    America's school districts "spent billions on technology during the pandemic," reports the Washington Post. "But now some states are limiting in-school screen time because of concerns about its impact on children." Nationwide [U.S.] schools invested at least $15 billion and possibly as much as $35 billion from federal pandemic relief funds on laptops, learning software and other technology between 2020 and 2024, according to an estimate by the Edunomics Lab, an education think tank. By last school year, 88% of public schools reported in a federal survey they had given every child a laptop, tablet or similar device. Now, some states and school districts are walking back their technology use following pressure from parents who claim too much in-school screen time has zapped children's attention spans and left them worse off academically. At least a dozen states introduced or adopted policies this year that attempt to regulate screen time in schools — from prescribing limits to allowing families to opt out of virtual instruction... In Missouri, a bill would require every school district in that state to come up with a screen time policy is making its way through the state legislature. "Ed tech is just big tech in a sweater vest," said Missouri state Rep. Tricia Byrnes (R), who introduced the legislation and blames what she described as the overuse of technology for middling test scores... Complicating the issue is research that shows students do not see any academic gains when provided with laptops. A meta-analysis of studies on reading comprehension suggests paper-based texts are better than digital-based reading... A body of research has established that excessive or unstructured screen time can have detrimental effects on children, including harming language development, weakening social skills and triggering anxiety and depression. But the effects of school-issued devices and in-school usage on children's development are less understood, said Tiffany Munzer, a developmental behavioral pediatrician and digital media researcher at the University of Michigan. Some studies report that high-quality digital tools can support students' learning goals, Munzer said. But "a lot of the apps that are marketed as educational ... are not actually educational and contain a lot of commercialized content." Read more of this story at Slashdot.

  • Humanoid Robot Becomes Buddhist Monk In South Korea
    by BeauHD on 09/05/2026 at 11:00 am

    A four-foot humanoid robot named Gabi has become a monk at a Buddhist temple in Seoul, participating in a modified initiation ceremony where it pledged to respect life, obey humans, act peacefully toward other robots and objects. "Robots are destined to collaborate with humans in every field in the future," Hong Min-suk, a manager at the Jogye Order, the largest sect of Buddhism in South Korea, tells the New York Times. "It will only be natural for them to be part of our festival." Smithsonian Magazine reports: For the temple, this marks the first time a robot has participated in the sugye initiation ceremony, when followers pledge their devotion to the Buddha and his teachings. Gabi -- a Buddhist name that refers to mercy, Yonhap News Agency reports -- was made by Unitree Robotics, a Chinese civilian robotics company. The model, G1, retails starting at $13,500. During the ceremony, Gabi agreed to five vows usually recited by human monks and slightly altered for the humanoid. The robot pledged to respect life, act with peace toward other robots and objects, listen to humans, refrain from acting or speaking in a deceptive manner and save energy. Gabi participated in a modified yeonbi purification ritual. While a human monk normally receives a small incense burn on the arm, instead Gabi received a lotus lantern festival sticker and a prayer bead necklace. The landmark event aligns with the promise made during a New Year's address by the Venerable Jinwoo, president of the Jogye Order of Korean Buddhism, to incorporate artificial intelligence into the Buddhist tradition. "We aim to fearlessly lead the A.I. era and redirect its achievements toward the path of attaining peace of mind and enlightenment," he said, per a statement. Read more of this story at Slashdot.

  • Fiber Optic Cables Can Eavesdrop On Nearby Conversations
    by BeauHD on 09/05/2026 at 7:00 am

    sciencehabit shares a report from Science Magazine: Cold War spies planted bugs in walls, lamps, and telephones. Now, scientists warn, the cables themselves could listen in. A fiber optic technique used to detect earthquakes can also pick up the faint vibrations of nearby speech, researchers reported this week here at the general assembly of the European Geosciences Union. Freely available artificial intelligence (AI) software turned the fiber optic data into intelligible, real-time transcripts. "Not many people realize that [fiber optic cables] can detect acoustic waves," says Jack Lee Smith, a geophysicist at the University of Edinburgh who presented the result. "We show that in almost every case where you use these fibers, this could be a privacy concern." Fiber optics can pick up on sound through a technique called distributed acoustic sensing (DAS). Using a machine called an interrogator, researchers fire laser pulses down a cable and record the pattern of reflections coming back from tiny glass defects along the length of the fiber optic. When an earthquake's seismic wave crosses a section of the fiber, it stretches and squeezes the defects, leading to shifts in the reflected light that researchers can use to build a picture of an earthquake. DAS essentially turns a fiber cable into a long chain of seismometers that can detect not only earthquakes, but also the rumblings of volcanoes, cars, and college marching bands. And although scientists set up dedicated fiber lines specifically for research, DAS can also be performed on "dark fiber" -- unused strands in the web of fiber optics that runs through cities and across oceans, carrying the world's internet traffic. DAS can also be used to eavesdrop, the work of Smith and his colleagues shows. They conducted a field test using an existing DAS setup used to study coastal erosion. They set a speaker next to the cable and played pure tones, music, and speech. Human speech contains frequencies ranging from a few hundred to several thousand hertz. The low end of the range could be pulled out of the data "even without any preprocessing," Smith says. "You can easily see acoustic waves." Getting higher frequency speech took a bit of postprocessing, but it was possible. Dumping the data directly into Whisper, a free AI transcription tool, provided accurate real-time transcription. However, this technique worked only for coiled cables, exposed at the surface, at distances of up to 5 meters from the speaker. Burying the cable under just 20 centimeters of dirt was enough to muddy the speech. And straight cables -- even exposed ones right next to the speaker -- did not record speech well.
