Earthquake of magnitude 5.5 strikes southwest Tibet
A 5.5-magnitude earthquake struck the city of Shigatse in southwestern Tibet on Monday, according to Chinese authorities.
The earthquake occurred at a shallow depth of 10km at 5.11am local time (2111 GMT). China's Earthquake Administration authorities said emergency services were deployed and that no casualties have been reported so far.
Shigatse lies in the southwestern part of Tibet and is the region's second-largest city.
Earlier, on 8 May, an earthquake of magnitude 3.7 jolted the region.
Monday's tremor comes just months after a devastating 6.8-magnitude earthquake hit Tingri county – about 240km (149 miles) from Shigatse – in January, killing more than 120 people and injuring more than 180.
The quake in January was felt across Nepal, Bhutan, and India. It was caused by deep tectonic shifts in the Lhasa block, part of the ongoing collision between the Indian and Eurasian plates.
The United States Geological Survey recorded the earthquake at a magnitude of 7.1, while the China Earthquake Networks Center measured it at 6.8.
Tibet has experienced multiple massive earthquakes over the past few decades, including a devastating 8.6-magnitude quake in 1950.
According to a study published last year, the Indian tectonic plate – which collided with the Eurasian plate – is now gradually tearing apart beneath Tibet. This phenomenon, known as a 'slab tear', occurs when the upper crust of the Indian plate separates from its denser lower layer, generating considerable seismic activity.
While this deep subterranean rift is unlikely to produce visible surface fractures, it has the potential to geologically divide Tibet into two distinct zones.
Scientists are closely monitoring the region, analysing seismic waves, deep-focus quakes, and gas emissions to better understand the risks posed by this evolving tectonic shift.

Cancer treatment turbocharges patients' own blood cells to kill solid tumours for first time
A LIVING cancer drug has been proven to work against solid tumours for the first time. Immune-boosting CAR-T therapy removes a patient's white blood cells and engineers them into highly specialised cancer killers in a lab. 1 They are then injected back into the patient and let loose against the disease. It is currently only used for blood cell cancers like leukaemia but research by Peking University in China has found it can also work against tumours that form as lumps. In a study of 266 people with stomach cancer, patients who received the treatment survived an average of 7.9 months compared to 5.5 months without it. It took 3.3 months for their cancer to worsen, compared to 1.8 months without. Study author Dr Changsong Qi said the results showed a 'significant increase in progression-free survival and clinically meaningful increase in overall survival'. More than 90 per cent of cancers are solid tumours that grow as a physical mass, including the big four of bowel, breast, lung and prostate. The findings raise the hope that tens or even hundreds of thousands more patients will one day benefit from the pioneering approach using their own immune systems instead of harsh drugs. 'Groundbreaking milestone' Dr Carl June, of the University of Pennsylvania, is credited with inventing the therapy and commented: 'This is a groundbreaking milestone for the field of CAR-T therapies against solid tumours.' CAR-T therapy, full name chimeric antigen receptor T-cell therapy, is an advanced type of immunotherapy that turbocharges the body's own defences to fight off cancer. It is intended to be more accurate and cause less collateral damage and side effects by only attacking cancerous cells and not healthy ones. Sun Health Explainer: What is cancer? Young Sunderland fan Bradley Lowery took part in a major clinical trial of it in 2017 before dying from neuroblastoma aged six. It is currently available on the NHS in England for certain types of leukaemia and lymphoma. More than 650 forms of the treatment are now in development for solid cancers. Dr John Haanen, from the Netherlands Cancer Institute, said: 'There is clearly now evidence that this treatment can benefit patients with solid cancers. It is an important development.' The study was published in The Lancet and presented at the conference of the American Society for Clinical Oncology. Dr Catherine Elliott, of Cancer Research UK, said: 'This is an encouraging early sign and further trials will now be needed.'

China paraglider's thundercloud survival claim featured likely AI-faked video
BEIJING/SYDNEY, June 1 (Reuters) - A Chinese paraglider's account of having been unwittingly swept into a thundercloud and dragged 8 km (5 miles) into the sky has come under question after his video of the incident, carried by Chinese state media, turned out to have been likely faked in part. The video, originally posted after the paraglider's May 24 flight by his support team on Douyin, China's TikTok, employed artificial intelligence to fake some of the footage, according to a review by a digital security firm consulted by Reuters. The video's opening showed Peng Yujiang, 55, among the clouds, his face encrusted with ice. The video, which caused a sensation in paragliding circles, was aired in China and distributed internationally by state-run broadcaster CCTV. Other news providers also distributed the video, which was picked up globally. California-based digital security firm GetReal said it was 'fairly confident' the first five seconds of Peng Yujiang's video contained AI-generated images. There are also inconsistencies noted by GetReal and paragliders who pored over the video: Peng's legs are initially dangling without the insulating cocoon shown later. His helmet is first white, then black. Still, five expert paragliders interviewed by Reuters said it was possible Peng had flown to 8,589 metres (28,179 feet) as he claimed and survived. But four of them also challenged his claim that the flight had been an unavoidable accident, which Reuters is reporting for the first time. The current record for a planned flight is held by French pilot Antoine Girard who flew 8,407 metres over a stretch of the Himalayas in 2021. Peng recorded and then deleted his flight log on XContest, a website popular among paragliders, according to Jakub Havel, a Czech paraglider who helps run the forum. Havel said other flights by Peng remained on the site. "Nobody intentionally lets themselves be sucked into a thunderstorm cloud in an attempt to break a record - it's something that any sane paragliding pilot tries to avoid at all costs," said Havel, who said Peng's flight should not be considered a record. Peng could not be reached for comment. CCTV, which distributed the video on a platform owned by Reuters, could not be reached for comment. Like other Chinese media, CCTV faces a pending regulation from Beijing that requires all AI-generated content to be labeled as such from September. Contacted on the weekend, China's State Council, which oversees and coordinates government policy, had no immediate comment. In a statement, Reuters said it had removed the CCTV package on Peng's flight from Reuters Connect, an online marketplace that carries material from more than 100 news organizations. 'This content is clearly labelled as third-party content and is not verified or endorsed by Reuters,' the statement said. 'When we became aware of a piece of content that likely contained AI-generated elements on the Reuters Connect platform, we investigated and took it down because the material does not comply with our partner content policy.' STORM CLOUDS In a report published on Wednesday, the Gansu Aeronautical Sports Association said Peng had broken an altitude record after being swept off the ground by a strong wind while testing second-hand gear he had just bought. 'According to Peng, he didn't plan on taking off,' the report said. The association, a private group that oversees air sports in the province, did not respond to a request for comment. It deleted its report on Peng's flight from its WeChat account and by Thursday the association's website was blocked. The association suspended Peng from flying for six months. A member of his flight team was suspended for six months for releasing the video without authorization. Expert pilots interviewed by Reuters said there were reasons to doubt Peng's flight was a fluke accident, saying he was either trying to make an unauthorized high ascent or should have seen the risk. Storm clouds like the one Peng flew in 'don't just appear above your head and hoover you into space. They build over a period of time,' said Daniel Wainwright, a flight instructor in Australia. 'He shouldn't have been flying.' The specialized heavy mittens shown in the video seem to undercut Peng's claim he had not intended to take off, said Brad Harris, president of the Tasmanian Hang Gliding and Paragliding Association. He said he believed Peng may have made up the accidental take-off to avoid sanction for entering restricted air space. 'These are not things you would normally wear or have ready if you were just ground-handling to test a wing,' Harris said. Godfrey Wenness, a former paragliding distance world record holder, said a veteran paraglider could have managed to reverse the extreme but manageable ascent shown in Peng's flight data. 'He was either inexperienced or he was trying to (keep climbing),' Wenness said. Wenness said, however, he believed Peng hit the altitude he claimed based on flight data posted on XContest and then deleted. That data has to be transferred from a GPS in a "tamper-proof" format, he said. "We conclude and are confident that the actual flight did occur," he said.

Innovative treatment effective in patients with certain tumours, study suggests
An innovative treatment that reprogrammes immune cells to recognise and kill cancer has been shown to be effective on patients with certain tumours in a pioneering trial. CAR T-cell therapy is usually used to treat some types of blood cancer. It involves genetically modifying a patient's T cells – a type of white blood cell – in a lab, before returning them to the bloodstream. A new first of its kind trial explored the use of the treatment in patients with advanced stomach cancer and gastroesophageal junction (GEJ) cancer, which develops at the point where the oesophagus meets the stomach. The phase two study, led by researchers in China, included people diagnosed with advanced stomach or GEJ cancer which had not responded to two previous lines of treatment. Some 104 patients were earmarked for CAR T-cell therapy while 52 were given standard care, which included a selection of drugs chosen by their doctor. Those who had CAR T-cell therapy lived an average for 7.9 months, compared to 5.5 months with standard care. Patients who received the treatment also spent 3.3 months without their cancer progressing compared to 1.8 months in the standard group. Researchers said that the study is the 'first randomised controlled trial of CAR T-cell therapy in solid tumours globally' and shows the treatment 'resulted in a significant improvement in progression-free survival, with a manageable safety profile'. They added that the findings, published in the Lancet and presented at the American Society of Clinical Oncology (ASCO) annual meeting in Chicago, support CAR T-cell therapy 'as a new third-line treatment' for patients with advanced stomach and GEJ cancer.
