Nepal uses drones to clean up Mount Everest's trash-covered slopes
Sherpas working on Mount Everest carry all that and more – 20 kilograms (44 pounds) per person – navigating a four-hour hike that traverses crumbling glacial ice and treacherous crevasses to bring trash back to base camp.
During the most recent climbing season, they had new help from two giant SZ DJI Technology Co. drones, which can complete the same journey in six minutes, sharing the task of clearing an expanding volume of refuse piling up on the world's highest peak.
Drones have been deployed to haul garbage from Everest's Camp 1, which sits at 6,065 metres (19,898 feet) above sea level, down to base camp, about 700 metres below. After a DJI FlyCart 30 delivers supplies like ropes and ladders up the peak, Sherpas hook on a debris-filled garbage bag for the drone's return journey as it buzzes down the mountain, sounding like an oversized mosquito.
Between mid-April and mid-May, the drones operated by Nepal-based firm Airlift Technology handled more than 280 kilograms of refuse, according to the Sagarmatha Pollution Control Committee, a local non-profit that manages trash collection on Everest.
The drones are part of a growing effort to clean the slopes of the mountain, which has become so trash-strewn it's been referred to as the 'world's highest garbage dump.' Enlisting robots can help not only speed up the process but also reduce the danger for the Sherpas carrying decades-worth of garbage down the treacherous peak.

Hong Kong stocks on course for nearly 4-year high on Tencent earnings beat
A stellar run on Hong Kong stocks gained traction on Thursday, with the benchmark heading for a level not seen in almost four years after better-than-expected earnings by Tencent Holdings added to signs that China's economic activity is picking up. The Hang Seng Index rose 0.2 per cent to 25,674.25 as of 10.56am local time, on track for its highest close since November 16, 2021. The Hang Seng Tech Index gained 0.1 per cent. On the mainland, the CSI 300 Index climbed 0.7 per cent and the Shanghai Composite Index added 0.3 per cent. Tencent, the second-biggest weighting on the Hang Seng Index, gained 1 per cent to HK$592. Semiconductor Manufacturing International advanced 3.8 per cent to HK$54.05 and Anta Sports Products added 2.9 per cent to HK$92.60. Second-quarter net income for Tencent rose 16 per cent from a year ago to 55.6 billion yuan (US$7.8 billion) based on the global accounting standard, the social-media giant said on Wednesday after the market closed. That beat the consensus estimate of 50.8 billion yuan in a Bloomberg survey of analysts. Sales increased for the 11th quarter, with a 15 per cent increase. 'Hong Kong stocks still have upside room,' said Yan Zhaojun, an analyst at Zhongtai Securities. 'Expectations for corporate earnings are stable. Earnings for the upstream industries will be revised upward because of China's move to cut excessive capacities in the anti-involution campaign.'

India's EV market shifts into high gear with Tesla debut – taking on Tata, JSW MG
Tesla opened its first showroom in India last month with little of its usual pomp, but the entry of Elon Musk's electric vehicle company still made a splash – and is further driving expectations for the South Asian nation's EV market. Indians have been quietly buying EVs. While still a niche segment in the world's third-largest car market, EVs are belatedly gaining ground, with a fierce battle emerging between new players and the once dominant Tata Motors. JSW MG Motor India – a joint venture between the country's JSW group and China's SAIC Motor – is leading the charge, growing its market share from under 1 per cent in February 2020 to 30 per cent by June this year. This was largely driven by the success of the Windsor EV it launched late last year, according to the Financial Express daily. JSW MG Motor India launched the Windsor EV in September last year. Photo: Handout That has come at a cost to Tata Motors, whose once dominant share of India's electric vehicle car market nearly halved to 38 per cent in July – despite recording its highest monthly sales.

US secretly embeds trackers in AI chip shipments to catch smuggling to China, sources say
US authorities have secretly placed location tracking devices in targeted shipments of advanced chips they see as being at high risk of illegal diversion to China, according to two people with direct knowledge of the previously unreported law enforcement tactic. The measures aimed to detect artificial intelligence chips being diverted to destinations that were under US export restrictions, and applied only to select shipments under investigation, the people said. They show the lengths to which the US has gone to enforce its chip export restrictions on China, even as the Trump administration has sought to relax some curbs on Chinese access to advanced American semiconductors. The trackers could help build cases against people and companies who profit from violating US export controls, said the people who declined to be named because of the sensitivity of the issue. Location trackers are a decades-old investigative tool used by US law enforcement agencies to track products subject to export restrictions, such as aeroplane parts. They had been used to combat the illegal diversion of semiconductors in recent years, one source said. US trackers have been found in shipments of Nvidia chips, sources say. /TNS
