CNBC reports that U.S. airlines have "canceled hundreds of flights to airports in Puerto Rico and Aruba, according to flight tallies from FlightAware and carriers' sites." JetBlue, Southwest, and American Airlines were among the multiple airlines showing cancelled flights, which "included close to 300 flights to and from San Juan, Puerto Rico's Luis Muñoz Marín International Airport, more than 40% of the day's schedule, according to FlightAware." Airlines canceled flights throughout the Caribbean on Saturday following U.S. strikes on Venezuela after the Federal Aviation Administration ordered commercial aircraft to avoid airspace in parts of the region.... It wasn't immediately clear how long the disruptions would last, though such broad restrictions are often temporary. Airlines said they would waive change fees and fare differences for customers affected by the airspace closures who could fly later in the month. CNN cites a U.S. official who says more than 150 U.S. aircraft (including helicopters) launched from 20 different bases "on land and sea" during Friday's attack. The U.S. has said the lights were out in Caracas during the attack, presumably because of a targeted strike on their power grid. "Videos filmed by Caracas residents showed parts of the city in the dark," reports the Miami Herald. United Nations secretary-general António Guterres issued a statement via his spokesman saying he was "deeply concerned that the rules of international law have not been respected," (according to a Reuters report cited by the Guardian). The Guardian adds that "a number of nations have called for an emergency meeting of the UN Security Council, in New York, today, as a result of the U.S.'s unilateral action."

86 aircraft were affected by an incident in Denver ,and 256 more in Dallas-Fort Worth, America's Federal Aviation Admistrationtold the Washington Post: The pilots flying into Denver International Airport could tell something was wrong. In urgent calls to air traffic controllers, they reported that the Global Positioning System was going haywire, forcing them to rely on backup navigation systems for more than a day. The Federal Aviation Administration issued a warning to air traffic in the area. Eight months later, in October 2022, it happened again — this time at Dallas-Fort Worth International Airport, which shut down a runway as pilots and air traffic controllers scrambled over two days without GPS to guide them. Federal officials have not said who was responsible for interfering with the systems or why it took so long to get them back online, though they've said the Denver incident was unintentional. But the disruptions stoked fear about the security vulnerabilities of GPS, a satellite network relied on daily by 6 billion people, businesses and governments. Over the past two years, interference with the U.S. Global Positioning System has grown dramatically, threatening a network that is highly vulnerable to attack in a conflict. The danger could be posed by enemy or rogue nation-states — or even just hobbyists with commercially available equipment. Efforts by the Pentagon to upgrade GPS have been delayed by years and have cost billions, as adversaries are developing increasingly sophisticated ways to jam and trick the system with false signals that make it think it is somewhere it isn't. And it's not just civilian airline traffic at risk. The underpinnings of modern life and entire economies could be disrupted by a broad attack on the fragile satellite system — power grids, financial systems, cellphone networks — raising the prospect of catastrophe in an era of increasing electronic warfare... A report last year by the OpsGroup, an organization of international airline operators, found that in January 2024, about 300 flights per day were affected by GPS interference. By late last year, that number had grown to 1,500 flights per day as conflicts in Eastern Europe and the Middle East continued. And in a one-month period, between July and August last year, some 41,000 flights were affected. "While GPS interference is not a new phenomenon, the scale and effects of the current wave of spoofing are unprecedented," the report found... The Pentagon has launched eight of its next-generation GPS III satellites, which broadcast the military-grade signal that is more resistant to jamming and spoofing. Lockheed Martin, the contractor building the satellites, is also developing a next-generation spacecraft, which would have the ability to emit an even stronger "spot beam" directly to areas used by U.S. forces, making it even more difficult to jam.

AI startups now outnumber all publicly traded U.S. companies, according to a year-end note to investors from economists at Vanguard. And yet that report also suggest the jobs most susceptible to replacement by AI "are actually thriving, not dying out," writes Forbes: "The approximately 100 occupations most exposed to AI automation are actually outperforming the rest of the labor market in terms of job growth and real wage increases," the Vanguard report revealed. "This suggests that current AI systems are generally enhancing worker productivity and shifting workers' tasks toward higher-value activities..." The job growth rate of occupations with high AI exposure — including office clerks, HR assistants, and data scientists — increased from 1% in pre-COVID-19 years (2015 through 2019) to 1.7% in 2023 and beyond, according to Vanguard's research. Meanwhile, the growth rate of all other jobs declined from 1.1% to 0.8% over the same period. Workers in AI-prone roles are getting pay bumps, too; the wage growth of jobs with high AI exposure shot up from 0.1% pre-COVID to 3.8% post-pandemic (and post-ChatGPT). For all other jobs, compensation only marginally increased from 0.5% to 0.7%... As technology improves production and reallocates employee time to higher-value tasks, a smaller workforce is needed to deliver services. It's a process that has "distinct labor market implications," Vanguard writes, just like the many tech revolutions that predate AI... "Entry-level employment challenges reflect the disproportionate burden that a labor market with a low hiring rate can have on younger workers," the Vanguard note said. "This dynamic is observed across all occupations, even those largely unaffected by AI..." While many people see these labor disruptions and point their fingers at AI, experts told Fortune these layoffs could stem from a whole host of issues: navigating economic uncertainty, resolving pandemic-era overhiring, and bracing for tariffs. Vanguard isn't convinced that an AI is the reason for Gen Z's career obstacles. "While statistics abound about large language models beating humans in computer programming and other aptitude tests, these models still struggle with real-world scenarios that require nuanced decision-making," the Vanguard report continued. "Significant progress is needed before we see wider and measurable disruption in labor markets."

A small section of the International Space Station that has experienced persistent leaks for years appears to have stopped venting atmosphere into space. ArsTechnica: The leaks were caused by microscopic structural cracks inside the small PrK module on the Russian segment of the space station, which lies between a Progress spacecraft airlock and the Zvezda module. The problem has been a long-running worry for Russian and US operators of the station, especially after the rate of leakage doubled in 2024. This prompted NASA officials to label the leak as a "high likelihood" and "high consequence" risk. However, recently two sources indicated that the leaks have stopped. And NASA has now confirmed this. "Following additional inspections and sealing activities, the pressure in the transfer tunnel attached to the Zvezda Service Module of the International Space Station, known as the PrK, is holding steady in a stable configuration," a space agency spokesman, Josh Finch, told Ars. "NASA and Roscosmos continue to monitor and investigate the previously observed cracks for any future changes that may occur." For the better part of half a decade, Russian cosmonauts have been searching for the small leaks like a proverbial needle in a haystack. They would periodically close the hatch leading to the PrK module and then, upon re-opening it, look for tiny accumulations of dust to indicate the leak sites. Then the Russian cosmonauts would apply a sealant known as Germetall-1 (which has now been patented) to the cracks. They would close the hatch again, monitor the pressure inside the PrK module, and begin the search anew for additional leaks. This process went on for years.

New York City's statewide smartphone ban that went into effect this fall has been largely successful at getting students to focus in class and socialize at lunch, but teachers across the city have discovered an unexpected side effect: many teenagers cannot read analog clocks. "The constant refrain is 'Miss, what time is it?'" said Madi Mornhinweg, a high school English teacher in Manhattan, who eventually started responding by asking students to identify the big hand and little hand themselves. Tiana Millen, an assistant principal at Cardozo High School in Queens, said the ban has helped move foot traffic more swiftly through hallways and gotten more students to class on time -- they just don't know it because they can't read the wall clocks. The city's education department says students learn clock-reading in first and second grade. A 2017 Oklahoma study found only one in five children ages 6-12 could read analog clocks, and England began replacing classroom analog clocks with digital ones in 2018.

A new sweeping meta-analysis has found no reliable link between economic inequality and well-being or mental health, challenging a long-held assumption that has shaped public health policy discussions for decades. The study, led by Nicolas Sommet at the University of Lausanne and Annahita Ehsan at the University of British Columbia, synthesized 168 studies involving more than 11 million participants across most world regions. The researchers screened thousands of scientific papers and contacted hundreds of researchers to compile the dataset, extracting more than 100 study features from each paper and linking them to more than 500 World Bank indicators. They also replicated their findings using Gallup World Poll data spanning 2005 to 2021, which surveyed more than two million respondents from more than 150 countries. People living in more economically unequal places did not, on average, report lower life satisfaction or happiness than those in more equal places. The average effect across studies was not statistically significant and was practically equivalent to zero. Studies that did find links between inequality and poorer mental health turned out to reflect publication bias, where small, noisy studies reporting larger effects were over-represented in the literature. The study adds: Further analyses showed that the near-zero averages conceal more-complex patterns. Greater income inequality was associated with lower well-being in high-inflation contexts and, surprisingly, higher well-being in low-inflation contexts. Greater inequality was also associated with poorer mental health in studies in which the average income was lower. We conclude that inequality is a catalyst that amplifies other determinants of well-being and mental health (such as inflation and poverty) but on its own is not a root cause of negative effects on well-being and mental health.

Dell is planning to bring back its XPS laptop branding, according to a news report, just one year after the company retired the storied name in favor of a simplified naming scheme that organized its consumer and professional lineup into Dell, Dell Pro and Dell Pro Max tiers. VideoCardz reported this week that Dell has presented an updated XPS lineup during prebriefings ahead of CES 2026, though the company has not officially confirmed the badge's return. The reported reversal would come after Dell launched the Dell 14 Premium and Dell 16 Premium in mid-2025 as flagship consumer models meant to carry the XPS legacy forward. Those machines replaced the XPS 14 and XPS 16 in Dell's lineup.
