  • Smartphones At Age 12 Linked To Worse Health
    by BeauHD on 02/12/2025 at 12:45 am

    A new study from the University of Pennsylvania finds that preteens who own smartphones by age 12 have significantly higher odds of depression, obesity, and poor sleep compared to their peers. Axios reports: Kids who owned a smartphone at age 12 were found to have about 31% higher odds of depression, 40% higher odds of obesity and 62% higher odds of insufficient sleep than their peers who didn't have one. The researchers analyzed data from the National Institutes of Health-supported Adolescent Brain Cognitive Development Study assessments conducted between 2016 and 2022. The study included responses from 10,588 youths. Kids who had smartphones were more likely to be female, Black or Hispanic, and from lower-income households. The study has been published in the journal Pediatrics. Read more of this story at Slashdot.

  • Apple AI Chief Retiring After Siri Failure
    by BeauHD on 02/12/2025 at 12:23 am

    Apple's longtime AI chief John Giannandrea is retiring, with former Microsoft and Google AI leader Amar Subramanya stepping in to take over. MacRumors notes the retirement comes after the company's repeated delays in delivering its revamped Siri and internal turmoil that led to an AI team exodus. From the report: Giannandrea will serve as an advisor between now and 2026, with former Microsoft AI researcher Amar Subramanya set to take over as vice president of AI. Subramanya will report to Apple engineering chief Craig Federighi, and will lead Apple Foundation Models, ML research, and AI Safety and Evaluation. Subramanya was previously corporate vice president of AI at Microsoft, and before that, he spent 16 years at Google. He was head of engineering for Google's Gemini Assistant, and Apple says that he has "deep expertise" in both AI and ML research that will be important to "Apple's ongoing innovation and future Apple Intelligence features." Some of the teams that Giannandrea oversaw will move to Sabih Khan and Eddy Cue, such as AI Infrastructure and Search and Knowledge. Khan is Apple's new Chief Operating Officer who took over for Jeff Williams earlier this year. Cue has long overseen Apple services. [...] Apple said that it is "poised to accelerate its work in delivering intelligent, trusted, and profoundly personal experiences" with the new AI team. "We are thankful for the role John played in building and advancing our AI work, helping Apple continue to innovate and enrich the lives of our users," said Apple CEO Tim Cook in a statement. "AI has long been central to Apple's strategy, and we are pleased to welcome Amar to Craig's leadership team and to bring his extraordinary AI expertise to Apple. In addition to growing his leadership team and AI responsibilities with Amar's joining, Craig has been instrumental in driving our AI efforts, including overseeing our work to bring a more personalized Siri to users next year."

  • Flock Uses Overseas Gig Workers To Build Its Surveillance AI
    by BeauHD on 02/12/2025 at 12:02 am

    An anonymous reader quotes a report from 404 Media: Flock, the automatic license plate reader and AI-powered camera company, uses overseas workers from Upwork to train its machine learning algorithms, with training material telling workers how to review and categorize footage including images people and vehicles in the United States, according to material reviewed by 404 Media that was accidentally exposed by the company. The findings bring up questions about who exactly has access to footage collected by Flock surveillance cameras and where people reviewing the footage may be based. Flock has become a pervasive technology in the US, with its cameras present in thousands of communities that cops use every day to investigate things like carjackings. Local police have also performed numerous lookups for ICE in the system. Companies that use AI or machine learning regularly turn to overseas workers to train their algorithms, often because the labor is cheaper than hiring domestically. But the nature of Flock's business -- creating a surveillance system that constantly monitors US residents' movements -- means that footage might be more sensitive than other AI training jobs. [...] Broadly, Flock uses AI or machine learning to automatically detect license plates, vehicles, and people, including what clothes they are wearing, from camera footage. A Flock patent also mentions cameras detecting "race." It included figures on "annotations completed" and "annotator tasks remaining in queue," with annotations being the notes workers add to reviewed footage to help train AI algorithms. Tasks include categorizing vehicle makes, colors, and types, transcribing license plates, and "audio tasks." Flock recently started advertising a feature that will detect "screaming." The panel showed workers sometimes completed thousands upon thousands of annotations over two day periods. The exposed panel included a list of people tasked with annotating Flock's footage. Taking those names, 404 Media found some were located in the Philippines, according to their LinkedIn and other online profiles. Many of these people were employed through Upwork, according to the exposed material. Upwork is a gig and freelance work platform where companies can hire designers and writers or pay for "AI services," according to Upwork's website. The tipsters also pointed to several publicly available Flock presentations which explained in more detail how workers were to categorize the footage. It is not clear what specific camera footage Flock's AI workers are reviewing. But screenshots included in the worker guides show numerous images from vehicles with US plates, including in New York, Michigan, Florida, New Jersey, and California. Other images include road signs clearly showing the footage is taken from inside the US, and one image contains an advertisement for a specific law firm in Atlanta.

  • Austria's Rebel Nuns Refuse To Give Up Instagram To Stay In Their Convent
    by BeauHD on 01/12/2025 at 11:20 pm

    Three Austrian nuns in their 80s who escaped a care home and reclaimed their old convent are refusing the church's offer to stay because it requires them to quit Instagram, stop speaking to the press, and avoid legal counsel -- conditions they call a gag order. Their standoff with church authorities has now escalated to the Vatican as the nuns continue posting to their 185,000 followers. NPR reports: Before the church authorities moved the nuns into care almost two years ago, the local abbey and Archdiocese of Salzburg acquired the convent. The sisters say they were not aware they were signing away what they understood to be their lifelong right to remain in the cloister. On Friday, their superior, Provost Markus Grasl from Reichersberg Abbey, announced that the sisters can stay. But his offer comes with conditions: The nuns must cease all social media activities, stop talking to the press and forgo seeking legal advice. The nuns have rejected the proposal, and now Grasl has called on the Vatican to intercede. In a statement released Friday, the nuns said the provost's offer is nothing short of a gag order. Speaking via Instagram, Sister Regina said, "We can't agree to this deal. Without the media, we'd have been silenced." Sister Bernadette told Instagram followers: "We need to resolve this but any agreement we reach must be in accordance with God's will and shaped by human reason." [...] The provost's proposed agreement -- which NPR has seen -- also bans laypeople from entering the cloisters, including the sisters' helpers, many of whom they've known for decades and on whom the nuns now depend for help. Speaking to NPR on Monday, the provost's spokesperson, crisis PR manager Harald Schiffl, said that the provost does not understand why the nuns reject his offer and that, in response, he has requested the Vatican authorities responsible for religious orders to step in. The Vatican has not commented on the situation. So while they await news from Rome, the sisters continue to follow the papal Instagram account. Schiffl says the terms relating to the nuns' social media use are reasonable: "The abbey wishes to discontinue the sisters' social media accounts because what they show has very little to do with real religious life."

  • Zipcar To End UK Operations
    by BeauHD on 01/12/2025 at 10:40 pm

    "The car-sharing company, first launched in the U.S. in 2000, has been active in the UK since 2010 and has just under half a million members," writes Slashdot reader guesstral. "'I'm writing to let you know that we are proposing to cease the UK operations of Zipcar,' wrote Zipcar UK's general manager, James Taylor, in an email to members today. He went on to say that Zipcar will temporarily suspend new bookings after December 31, pending the outcome of a consultation with its 71 staff members." From the BBC: In its most recent company accounts for 2024, Zipcar blamed the "cost of living crisis," which was affecting UK customers, for revenues falling to 46 million pounds to 53 million the year before, while its after-tax losses had widened to 11.6 million pounds. According to the same accounts, Zipcar membership fees cover the cost of fuelling or charging the vehicle and, as energy costs continued to rise last year, it has added to financial pressures on the company. The company would also be liable for the incoming congestion charge in London that is expanding to include electric vehicles from 26 December, although this was not referenced in Zipcar's email to membership or company accounts.

  • Korea's Coupang Says Data Breach Exposed Nearly 34 Million Customers' Personal Information
    by BeauHD on 01/12/2025 at 10:00 pm

    An anonymous reader quotes a report from TechCrunch: South Korean e-commerce platform Coupang over the weekend said nearly 34 million Korean customers' personal information had been leaked in a data breach that had been ongoing for more than five months. The company said it first detected the unauthorized exposure of 4,500 user accounts on November 18, but a subsequent investigation revealed that the breach had actually compromised about 33.7 million customer accounts in South Korea. The breach affected customers' names, email addresses, phone numbers, shipping addresses, and certain order histories, per Coupang. More sensitive data like payment information, credit card numbers, and login credentials was not compromised and remains secure, the company said. [...] Police have reportedly identified at least one suspect, a former Chinese Coupang employee now abroad, after launching an investigation following a November 18 complaint.
