Shares in South Korean chipmaker SK Hynix tumble on US tariffs
SEOUL (Reuters) -Shares in South Korean chipmaker SK Hynix fell 3.1% in early Thursday trade, after President Donald Trump said the U.S. will impose a tariff of about 100% on chips. SK Hynix supplies Nvidia with chips called high-bandwidth memory used in artificial intelligence chipsets. Trump said on Wednesday the United States will impose a tariff of about 100% on semiconductors imported from countries not producing in the U.S. or planning to do so. But it would not apply to companies that had made a commitment to manufacture in the U.S. or were in the process of doing so. South Korea's trade envoy said on Thursday that SK Hynix and rival Samsung Electronics would not be subject to a 100% U.S. tariff on chips.

Chevy Just Set An Insane EV Range Record—In A Big Truck
Chevy Just Set An Insane EV Range Record—In A Big Truck originally appeared on Autoblog. No hardware or software changes were required to set a new record It's been a record-breaking month for Chevrolet. Already, the company set a new record for American cars at the Nürburgring with the Corvette ZR1 and ZR1X. Its latest record won't be as exciting for gearheads, as it involves the longest range on a full charge for an EV, but it's another stellar technical achievement. 300 miles is generally accepted as the psychological mark of a useful EV range, but Lucid far surpassed this by hitting 749 miles in the Air sedan last month—a record at the time. Chevy has now crushed that figure, and even more impressively, it pulled off the feat with a heavy, full-size pickup, not an aerodynamic 1,000 Miles On A Full Charge The record-breaking achievement came behind the wheel of a 2026 Chevrolet Silverado EV Max Range Work Truck, which went 1,059.2 miles on a full charge, breaking Lucid's 749-mile record. This truck is rated by the EPA for a 493 mile range, so how was it able to more than double that figure? GM says the record attempt began with a casual conversation between GM engineers late last year. They started guessing what sort of range they could achieve if the pickup could be optimized for range and efficiency. 'Getting this kind of range on a full charge doesn't happen by accident,' said Kurt Kelty, VP, battery, propulsion, and sustainability. 'It takes deep integration across battery chemistry, drive unit efficiency, software and vehicle engineering—and that's exactly what the team delivered. This achievement is a great example of how far our EV technology has come, and the kind of innovation we're building on every day at GM.'Real-World Test Sees Staggering Results The GM team performed the record-breaking test on public roads in southeastern Michigan, close to GM's Milford Proving Ground. The team optimized every feasible aspect of the truck, but left the hardware and software as is. While it's technically possible for owners of the truck to put some of these optimizing measures in place, combining them all will be just about impossible in normal driving. These were the measures taken by the team: When conditions allowed, drivers averaged 20 to 25 mph, and hard braking was minimized No passengers were in the truck for most of the test Windshield wiper arms were set to the lowest possible position, reducing drag The highest acceptable tire pressure was used, resulting in lower rolling resistance The wheel alignment was optimized and the spare tire was removed The climate control wasn't used at all For smoother airflow, an accessory tonneau cover was added The test occurred in warmer summer conditions None of these measures are particularly groundbreaking, but the cumulative effect clearly made all the difference. The various engineers who drove the truck did so in one-hour shifts, allowing them to incorporate the project into their normal work schedules. 'If we drove it downhill the whole time, sure, we'd get insane mileage,' said Jon Doremus, propulsion calibration engineering manager. 'But that's not what this was about. We wanted this to be real, on public roads.' The test suggests that by incorporating just a few of these measures, owners of this Chevy pickup should easily be able to squeeze over 500 miles of range from it, a commendable effort. The EPA rating of the Chevy is already better than all other rivals, including the Rivian R1T, Tesla Cybertruck, and Ford F-150 Just Set An Insane EV Range Record—In A Big Truck first appeared on Autoblog on Aug 6, 2025 This story was originally reported by Autoblog on Aug 6, 2025, where it first appeared.

Major work from home ‘turning point' as employees return the office: ‘Worst behind us'
Australia has reached a 'turning point' as more workers return to the office and vacancy rates begin to stabilise across the country's CBD offices. The shift comes as employers and employees continue to wrestle over work-from-home rights. Australia's CBD office markets are showing signs of recovery, with some major cities recording positive rates for the first time in years as workers head back to the office. The latest Property Council of Australia data found the CBD office vacancy rate had crept up from 13.7 to 14.3 per cent over the first six months of the year, but this was largely due to a wave of new office spaces hitting the market. Despite this, Ray White head of research Vanessa Rader said the data suggested 'the worst of the office market correction may be behind us'. RELATED Work from home rights could cost 1.8 million Australians their penalty rates Little-known Centrelink perk offers Australian students free flights Hidden way Aussies are cutting $20,000 from their tax bill every year The Sydney CBD vacancy rate increased from 12.8 to 13.7 per cent, due to high levels of supply outstripping demand. However, it recorded 56,532 square metres of annual net absorption of space, which was the highest on record since 2016. 'This positive absorption represents a dramatic shift from the negative trends that characterised the market through much of the post-pandemic period and suggests that return-to-office initiatives are gaining genuine traction among Sydney businesses,' Rader said. Melbourne CBD continues to face the most significant challenges with vacancy and saw rates drop from 18 to 17.9 per cent. The market saw a positive absorption of 1,446 square metres, which Rader noted was a 'meaningful shift' for the negative absorption recorded over the past three CBD markets recorded a combined net absorption of 63,738 square metres, which was some of the strongest performance in several years. Property Council chief executive Mike Zorbas said the group had now seen a year and a half of positive demand for office space and there were 'more businesses taking up office space than leaving behind'. Rader said the recovery appeared to be driven by several factors, including businesses implementing return-to-office policies. There's also demand for more premium CBD buildings. 'While the recovery trajectory remains gradual, the consistent positive absorption across multiple CBD markets suggests a genuine turning point,' Rader said. 'The challenge now will be maintaining this momentum through continued focus on workplace experience and flexible arrangements that meet evolving occupier needs.' The overall office vacancy rate across CBDs and suburban markets increased from 14.7 to 15.2 per cent, which is still its highest in three decades. Fears WFH plan will drive workers out of CBD It comes as the Victorian government pushes to make work from home a legal right. Under the Australian-first proposal, workers who could reasonably do their job from home would have a right to do so for at least two days a week. This would be for both the public and private sector. "Working from home saves working people and families time and money, and it makes good workers more productive," Premier Jacinta Allan said. Property Council Victorian executive director Cath Evans said the work-from-home mandate risked 'undermining confidence' in the office sector and came as it was showing 'green shoots'. 'Flexibility is and will remain core to many workplaces. But decisions about working arrangements should remain a matter between employers and their teams – not mandated by government,' she said. 'The reality is that investment to drive jobs, upgrade our office assets and keep our city vibrant will be deterred from Melbourne if this latest policy comes into effect.' Recent data from CBRE found 63 per cent of Melbourne residents attended the office in the first quarter of 2025, compared to the national average of 74.7 per cent. Sydney's office attendance was 82 per cent, while Brisbane's was 79 per cent.
