Replacement work on water pipe that gave Hongkongers scare to begin this year
Hong Kong will begin replacing a 400-metre (437 yards) section of water pipe lined with bitumen this year before carrying out citywide work, as it is believed to be the source of black particles dirtying the water at two public housing estates.

Secretary for Development Bernadette Linn Hon-ho said on Saturday that the government would prioritise the stretch of pipe between Queens Hill Estate and Shan Lai Court in Fanling, the only one lined with bitumen that connects the two sites.
She said the city had about 700km (435 miles) of pipes lined with the substance and her bureau had told the Water Supplies Department to submit a plan to replace old ones across the city.
'To allay public concerns, particularly because of the emergence of sediment at this site, we plan to start the replacement project within this year,' Linn said.
'We have asked the Water Supplies Department to submit a plan to replace old water pipes to the Development Bureau.'

The substance has been banned from use in water pipes in the city since 2005, but authorities have stressed that the water remains safe to consume after residents voiced worries over the presence of the black particles.
Linn said that bitumen-lined pipes were used internationally and posed no harm, with authorities also installing more than 1,000 filters in the water supply system.

Who created AI app MediSafe? Hong Kong student and US software firm stake claims
Two Hong Kong government departments have launched an investigation into an award-winning medication prescription app invented by a student that had already been in use by a clinic three years earlier, the Post has learned. Advertisement The Digital Policy Office and Education Bureau said they were studying the mobile app that a student surnamed Poon, from St Paul's Co-educational College in Mid-Levels, submitted in competitions as her invention. Poon declined to respond to online accusations calling her 'a fake inventor', but told the Post she was going through the verification process with competition organisers. Her father, Ronnie Poon Tung-ping, is one of two doctors at a specialist clinic in Central that commissioned a US-based artificial intelligence (AI) software development agency to create the app in 2022, which was subsequently deployed. The investigations were launched after the incident came to light on June 13, prompted by City University student Hailey Cheng, who raised concerns on social media platform Threads about the research and development culture in secondary schools' STEM education and competitions, as well as the privacy of patients using the MediSafe app. Advertisement MediSafe, a medication management system designed to prevent prescription errors through AI-driven verification of patient information, has won at least six awards since August last year. The honours include a silver medal in the 50th International Exhibition of Inventions, Geneva, in 2025, a prestigious globally recognised accolade.

Chinese swimmers had to have eaten 5kg of food to fail 2021 drug tests, Usada chief says
The head of the United States Anti-Doping Agency told senators that Chinese swimmers would have had to eat around 11 pounds (5kg) of food to test for the amounts of the performance enhancer that resulted in the much-debated positive drug tests from 2021 that were later disregarded. Advertisement 'It's unbelievable to think that Tinkerbell just showed up and sprinkled it all over the kitchen,' Travis Tygart said in a Senate hearing on Tuesday focused on the World Anti-Doping Agency's response to the doping case. A key part of that case was Wada's acceptance of the explanation from Chinese authorities that the swimmers had been contaminated by traces of the drug trimetazidine (TMZ) in a hotel kitchen. Usada scientists analysed data from a report commissioned by Wada to come up with the amount of food (5kg) or liquid (4.9 litres) the athletes would have had to have consumed to test positive at the levels they did. Wada officials declined to participate in the hearing, which spokesperson James Fitzgerald called 'another political effort led by Travis Tygart … to leverage the Senate and the media in a desperate effort to relitigate the Chinese swimming cases and misinform athletes and other stakeholders'. Advertisement Also testifying was former US drug tsar Rahul Gupta, whose decision at the start of this year to withhold US$3.6 million in funding – the biggest single chunk that Wada receives on an annual basis – furthered a long-running feud between US and Wada authorities.

Hong Kong to launch database for high-risk elderly carers this year
Hong Kong will launch a database this year to identify high-risk carers looking after the elderly, with the city recording more than 470 suicides among older residents annually, accounting for over 40 per cent of all cases. Secretary for Labour and Welfare Chris Sun Yuk-han said on Wednesday that the government was in discussions with the personal data privacy authorities to design data-sharing solutions that complied with the city's legal requirements. But he added that the government hoped to launch the new database as soon as possible this year. '[Authorities] and the Privacy Commissioner have roughly resolved how to connect and compare databases in accordance with the Personal Data (Privacy) Ordinance, but we will launch a pilot scheme first,' Sun told lawmakers at a Legislative Council meeting. 'We hope to launch the pilot scheme as soon as possible this year.' Statistics from the Coroner's Court showed that there were 472 suicides involving people aged 60 and above last year, on a par with the 473 and 477 recorded in 2023 and 2022, respectively. The database will include information on carers looking after older residents and those from low-income households.
