US firm brings prostate cancer therapy to Hong Kong, cutting surgery risks
An American medical technology firm has introduced a novel treatment in Hong Kong that uses electric pulses to kill prostate cancer cells while minimising the risks of incontinence and sexual dysfunction.
AngioDynamics, of Latham, New York, said its NanoKnife system delivers 'high-voltage, low-energy' electrical pulses to create irreversible electroporation (IRE), a form of damage that kills targeted cells. It was approved for marketing by the US Food and Drug Administration (FDA) in December.
'This allows a physician to destroy the targeted cells but preserve the underlying structure of the tissue,' said Jake Brumbaugh, the vice-president of oncology global marketing at the Nasdaq-listed firm.
'This unique mechanism of action means the NanoKnife system is extremely versatile, able to be used in any segment of an organ, even providing ablations across critical structures including nerves, the urethra and blood vessels.'
The voltage, typically in the range of 1,500 to 3,000 volts per centimetre between electrodes, varies depending on the tissue type and treatment plan, he said. The technology offers an alternative for patients whose cancer has yet to spread outside the prostate. Prostate cancer is the fourth most common cancer worldwide and the second most common among men, with 1.47 million new cases in 2022, according to the UK-based charity World Cancer Research Fund International. Nations that reported the most cases were the US, which accounted for 15.7 per cent of the total, followed by China at 9.1 per cent.

Keep fit and trim in midlife to age well – how diet that avoids weight gain pays dividends
Curbing or preventing middle-aged spread – the tendency to gain weight in midlife – could be key to avoiding serious medical problems in later life, doctors say. Advertisement The type and quality of carbohydrates a person consumes in their forties and fifties is likely to be a determining factor in how healthily they age, research shows. 'Sustained weight loss from overweight to healthy weight in midlife was associated with decreased risk of chronic diseases,' according to a team of doctors and scientists at the University of Helsinki and the University of Turku in Finland, and University College London in the United Kingdom. Achieving this weight loss without having surgery or taking drugs means 'long-term health benefits beyond its associations with decreased diabetes risk ', said the researchers, whose study covering around 23,100 people was published by the American Medical Association (AMA). Keeping trim in your forties and fifties, including by eating well, reduces the risk of developing chronic conditions such as diabetes, according to doctors and scientists from Finland and the UK. Photo: Shutterstock The AMA also recently published a study of around 47,000 women carried out by a team from Tufts University and Harvard University, both in the US state of Massachusetts, in which the researchers say fibre and carbohydrates are 'favourably linked to healthy ageing and other positive health outcomes in older women.'

Rethink measures against e-cigarettes for a smoke-free Hong Kong
Feel strongly about these letters, or any other aspects of the news? Share your views by emailing us your Letter to the Editor at letters@ or filling in this Google form . Submissions should not exceed 400 words, and must include your full name and address, plus a phone number for verification I refer to '70% of Hongkongers under 25 have tried e-cigarettes: university poll' ( May 23 ). While some support a complete ban on alternative smoking products (ASPs), their widespread use is crystal clear evidence that the current ban on selling ASPs is not working. This ban was imposed in 2022 and the tax on tobacco was increased twice, in 2023 and 2024. But between 2021 and 2023, the number of smokers only dropped by 9,200, a decline similar to previous years. With nearly 600,000 smokers remaining, is banning ASPs truly the best way to accelerate the drop in the smoking population and achieve a smoke-free Hong Kong? Around the world, there are more countries that regulate ASPs (more than 80) than ban them. The United Kingdom's 'swap to stop' programme and the United States Food and Drug Administration's authorisation to sell some products as 'modified risk tobacco products' are important examples of a global shift towards pragmatic, science-based solutions.

US Trojan horse alarms pushing China's robots to Europe
Chinese robot makers are expanding their presence in Europe amid the growing risk of having their products banned by Washington if the US-China technology war escalates. Distributors of Unitree Robotics and several others backed by Chinese technology giants such as Baidu, Alibaba and Tencent (a tech trio known as BAT), said at a recent event in London that Chinese firms are actively seeking European customers and partners. Aska Liu, founder and chief executive at EnduX, a United Kingdom-based distributor for Chinese robot makers, told Asia Times that many Chinese robotic firms are still collaborating with their US counterparts despite rising Sino-China political tensions. Aska Liu, founder and chief executive at EnduX, says Europe and China should collaborate in robotic technologies. Photo: Asia Times/Jeff Pao For example, she said that Physical Intelligence (Pi), a California-based AI firm founded in 2024, used AgiBot's hardware to develop their robotic brains. She said Chinese and US firms, which are good at hardware and brains, respectively, should collaborate and utilize each other's strengths. However, she noted that some Chinese players are now seeking to diversify their markets. 'We have seen a shift in focus of some Chinese players to Europe,' she said. 'They are saying: The US has so much instability and uncertainty. We don't want to put all eggs in one basket.' She suggested Europe could benefit from the changing political situation between the US and China, as Chinese robot makers want to build stronger relationships with the bloc. Liu said Europe is the best place in the world for Chinese firms to deploy robotic technologies because: Europe has labor shortage challenges; Europe has intense industrial and agricultural scenes for the deployment of robots; Europe is a global leader in regulations and a good gatekeeper for ethics, safety and standards; China has a complete electronic supply chain for companies to finish proof-of-concept (POC) and mass-produce their robots. She said Chinese robot makers should target markets related to research and education, inspection and patrolling, hospitality and services, material handling and so-called 'teleoperation', which allows workers in low-wage countries to control robots remotely and work in shops and factories in high-cost countries. At the same time, Chinese robots are under assault in America. On May 9, the US Congress' Select Committee on the Chinese Communist Party (CCP) said its members signed a bipartisan letter warning of a growing national security threat posed by Unitree's 'dual-use' robots. The committee called for an investigation into Unitree's connection to the People's Liberation Army (PLA) and whether the company's products contain built-in backdoors that transmit data back to China. It said China might use the robots' remote-access features to spy, gather intelligence or cause Trojan horse-like disruption inside the US. 'The fact that PLA-connected robots are operating in US prisons and even within Army operations should be a wake-up call,' said committee chairman John Moolenaar. 'These machines are not just tools—they are potential surveillance devices backed by the CCP.' In November 2022, the Federal Communications Commission banned the import of communications equipment made by China's Huawei Technologies and ZTE because they were 'deemed to pose an unacceptable risk to national security.' In early 2024, the Biden administration warned of potential national security risks associated with Chinese electric vehicle imports. Autodiscovery, a UK-based distributor for China's Unitree and AgileX, said on its website that it can disable all networking features if a customer wishes to use the robot in a secure environment. According to official footage, Unitree G1 and US robot maker Boston Dynamics' Atlas can move swiftly, but the latter can perform more complex tasks, such as precisely moving objects. Aron Kisdi, managing director at Autodiscovery, says Chinese robot makers aim to enhance their robots' ability to move objects. Photo: Asia Times/Jeff Pao 'In the recent demonstrations from Boston Dynamics, we have seen much more capability from the robot. It can pick up heavy objects and move them around in a facility. That is certainly a skill many of our clients are looking for,' said Aron Kisdi, managing director at Autodiscovery. 'The ability to do simple tasks like moving strange-shaped or heavy objects from one location to another in the factory is useful for our clients,' he said. 'Unitree platforms don't have the software capability out of the box, and we need to implement this specifically for the client whenever we find a new deployment. Boston Dynamics is ahead of this.' Kisdi said his company not only sells Chinese robots but also helps Chinese manufacturers understand the needs of European customers, enabling them to improve their research and development (R&D). 'We are increasingly talking to end users who don't have a robotics lab but want a functional robot in their facility doing useful things,' he said. 'By the end of 2026 or the beginning of 2027, we will have Unitree-based platforms with improved software that can go straight to clients.' Atlas is not yet available for sale. Its production cost is estimated to be between US$500,000 and $1 million. Unitree's G1 robot, which made global headlines in the world's first robotic kickboxing match in Hangzhou last month, is priced at only $16,000. 'I wouldn't categorize Chinese and US robots as low-end or high-end, but they are in different parts of the value chain,' Liu said. 'China is leading the hardware, manufacturing and design. We see all sorts of robots manufactured and designed in China, which are second to none. You won't be able to find this level of variety, quality, value for money or cost anywhere.' 'In a humanoid robot, 40 to 60% of its parts can be sourced from the supply chain of electric vehicles. China is very well developed in electric vehicles, and it's having an advantage,' she added. Founded by Liu in March 2023, EnduX sells robots for LimX Dynamics (backed by Alibaba Group and NIO Capital), AgiBot (backed by Tencent, BYD and Baidu), Deep Robotics and Kepler Exploration Robotics.

At the Humanoids Summit, held in London on May 29-30, Unitree displayed an H1 robot without turning it on, while Kingston University used a Unitree G1 robot to demonstrate some simple movements. EnduX demonstrated LimX's TRON1, a biped robot that can maintain balance on rough terrains. Booster Robotics, a Beijing-based company established in 2023, stole the show with its T1 robot playing football and performing with a human dancer. The T1 humanoid robot stands 1.2 meters and weighs 30 kilograms, compared with Unitree G1's 1.3 meters and 35 kilograms. A Booster T1 robot performs with a human dancer.

'As a startup, we have to differentiate our products. We want to make something robust to ensure our products don't break that much.' Li said Booster also invested in software development, with many of its team members having worked in companies like Microsoft. He said his company would build better hands for its robots to do sophisticated tasks. Read: China stages first-ever humanoid robot kickboxing match
