  • Airbus Issues Major A320 Recall, Threatening Global Flight Disruption
    by msmash on 29/11/2025 at 5:15 am

    Europe's Airbus said on Friday it was ordering immediate repairs to 6,000 of its widely used A320 family of jets in a sweeping recall affecting more than half the global fleet, threatening upheaval during the busiest travel weekend of the year in the United States and disruption worldwide. From a report: The setback appears to be among the largest recalls affecting Airbus in its 55-year history and comes weeks after the A320 overtook the Boeing 737 as the most-delivered model. At the time Airbus issued its bulletin to the plane's more than 350 operators, some 3,000 A320-family jets were in the air. The fix mainly involves reverting to earlier software and is relatively simple, but must be carried out before the planes can fly again, other than repositioning to repair centres, according to the bulletin to airlines seen by Reuters. Airlines from the United States to South America, Europe, India and New Zealand warned the repairs could potentially cause flight delays or cancellations. Read more of this story at Slashdot.

  • EU To Examine If Apple Ads and Maps Subject To Tough Rules, Apple Says No
    by msmash on 29/11/2025 at 5:01 am

    EU antitrust regulators will examine whether Apple's Apple Ads and Apple Maps should be subject to the onerous requirements of the bloc's digital rules after both services hit key criteria, with the U.S. tech giant saying they should be exempted. From a report: Apple's App Store, iOS operating system and Safari web browser were designated core platform services under the Digital Markets Act two years ago aimed at reining in the power of Big Tech and opening up the field to rivals so consumers can have more choice. The European Commission said that Apple has notified it that Apple Ads and Apple Maps met the Act's two thresholds to be considered "gatekeepers." The DMA designates companies with services with more than 45 million monthly active users and $79 billion in market capitalisation as gatekeepers subject to a list of dos and don'ts.

  • Scientists Think They've Solved Why One of History's Most Advanced Civilizations Vanished
    by msmash on 29/11/2025 at 2:02 am

    A new study published in Communications Earth & Environment has reconstructed the climate conditions of the ancient Indus River Valley civilization between 3000 and 1000 B.C., finding that four intense droughts -- each lasting more than 85 years -- likely drove the gradual decline of one of the world's earliest advanced societies. The research team, led by Hiren Solanki at the Indian Institute of Technology, Gandhinagar, combined paleoclimate data from cave formations and lake records with computer models to determine that the region shifted from wetter-than-present monsoon conditions to prolonged dry spells as the tropical Pacific Ocean warmed. The third drought, peaking around 1733 B.C., proved the most severe: it lasted 164 years, reduced annual rainfall by 13%, and affected nearly the entire region. Overall temperatures rose by 0.5 degrees Celsius and rainfall dropped between 10 and 20%. These changes shrank lakes and rivers, dried soils, and made agriculture increasingly difficult in areas away from major waterways. Harappan settlements progressively relocated eastward toward the Indus River over roughly 2,000 years. The civilization's long survival under repeated climate stress -- through crop switching, trade diversification, and settlement relocation -- offers lessons for modern communities facing environmental pressures, the researchers said.

  • China-Netherlands Chip Fight Turns Into Corporate Civil War
    by msmash on 28/11/2025 at 11:35 pm

    The bitter standoff between Dutch chipmaker Nexperia -- which supplies basic chips crucial to 49% of European automakers, over 85% of medical device companies, and the entire defense industry -- and its Chinese parent company Wingtech escalated on Friday when both Wingtech and Nexperia's Chinese unit accused the Dutch business of secretly building a supply chain that would cut China out entirely. The accusations came one day after Nexperia's Dutch headquarters published an open letter claiming it had repeatedly tried and failed to contact its Chinese unit. Nexperia China demanded the Dutch side halt its overseas expansion plans, specifically a $300 million investment in a Malaysian plant, and alleged an internal company target to source 90% of production outside China by mid-2026. The Chinese unit also accused its European counterparts of deleting employee email accounts and cutting off access to IT systems. The dispute traces back to September when the Dutch government invoked a Cold War-era law to seize control of Nexperia on economic security grounds. An Amsterdam court subsequently stripped Wingtech of its ownership rights. Beijing retaliated by halting exports of finished Nexperia chips on October 4, triggering warnings of production shutdowns from automakers including Nissan and Bosch. Export curbs were relaxed in early November, and the Dutch government suspended its intervention last week following talks, but the court ruling remains in force. Wingtech warned that supply disruptions could return if the control issue remains unresolved. Read more of this story at Slashdot.

  • Australia Risks 2035 Climate Goal Without Bigger Emissions Cuts
    by msmash on 28/11/2025 at 9:31 pm

    Australia warned it's in danger of missing its 2035 climate targets without deeper pollution cuts, which in turn threatens the nation's ambitions to reach net zero by mid-century. From a report: Emissions are set to fall 48% by 2035 from 2005 levels based on current projections [non-paywalled source], the government said in a report on Thursday. That's short of an official pledge to cut greenhouse gases between 62% and 70%. The forecast doesn't take into account new action planned under the nation's Net Zero Plan. Still, the targets remain achievable and officials plan to take additional measures to meet them, Minister for Climate Change and Energy Chris Bowen said in a speech to parliament.

  • Singapore Takes Top Spot in Global Talent Index
    by msmash on 28/11/2025 at 8:02 pm

    Singapore has claimed the top spot in the 2025 Global Talent Competitiveness Index for the first time, displacing Switzerland from a position the European nation had held since the ranking's inception in 2013. The index, produced by business school INSEAD and the Portulans Institute, measured 135 economies across 77 indicators spanning soft skills, AI talent concentration, and formal education systems. The city-state ranked first globally in formal education and what the report calls "Generalist Adaptive Skills," a category covering soft skills, digital literacy, and innovation-oriented thinking. A key factor in Singapore's rise was a seven-place jump in talent retention, moving from 38th to 31st. The United States fell from third place in 2023 to ninth this year, its weakest showing in 12 years, due to declines in openness and lifelong learning metrics. High-income European countries continue to dominate the top ten, holding seven positions. Read more of this story at Slashdot.
