In South Korea, blood cancer cases at Seoul Metro spark workplace safety concerns

Officials on Wednesday said two of the five workers had died from 'acute leukaemia', the Korea Times reported, citing a study by the Korea National Open University.
The affected workers were responsible for maintaining trains on Lines 1 through 8 of the Seoul Metro.
All five had spent years performing core maintenance tasks, including dismantling, cleaning, repairing, welding, grinding and repainting subway trains.
According to the Korea Times, one was diagnosed in 2009 at age 39 and retired three years later. Another was diagnosed in the same year and retired in 2011 at age 51. The remaining three are still employed.

The latest cases follow last year's discovery of eight other workers diagnosed with the same conditions – including three deaths – bringing the total number of affected employees at Seoul Metro to 13.

New Chinese see-through brain technique offers clearest view of its inner workings
Chinese scientists have developed a technology that can make organs such as the brain or the heart transparent, allowing an exceptionally clear view of their inner workings. The new method produced 'highly accurate and vivid' 3D images of organs by preserving the integrity of their biological structures and enhancing the brightness of the fluorescent dyes scientists use to highlight cells and molecules. The Tsinghua University-led team wrote in the journal Cell that this method was capable of unravelling individual human neurons' micro-connectivity in the brain as well as allowing them to study mouse organs '[The method] prepares ionic glassy tissue that is highly transparent while maintaining the original tissue morphology,' they wrote. They added that at low temperatures the tissues formed a glassy solid that maintained its structural integrity and could be stored over the long-term.

Grow senior fitness to solve China's youth unemployment

Submissions should not exceed 400 words, and must include your full name and address, plus a phone number for verification One solution to China's youth unemployment may lie in seniors. Most seniors in China take a reactive approach to health and fitness and tend to address issues only when they arise. While pharmacies, clinics and hospitals are readily available in many Chinese cities, fitness centres and gyms are less common. This break-fix model is detrimental to the healthcare system. This significant gap in the marketplace presents a valuable opportunity to promote proactive health and fitness programmes among seniors. Addressing this need could generate employment opportunities for youth, reduce healthcare costs and increase demand for real estate. In the United States, around 700,000 people are employed in gyms and fitness clubs. This figure includes roles such as personal trainers and support staff. China's population is almost four times that of the United States. Even at similar service levels, we could be looking at almost 3 million employment opportunities.

How mosquito-borne viruses chikungunya, dengue and Zika got their names
Chikungunya is on everybody's radar these days as cases increase significantly worldwide, including across Asia. 'That which bends up' is what the virus's name means in Kimakonde (also known as Makonde), a Bantu language of the Makonde ethnic group from southeast Tanzania and northern Mozambique, deriving from the verb kungunyala 'to assume a contorted position'. The moniker makes reference to one of the hallmark symptoms of the disease: along with abrupt onset of high fever, headache, nausea, fatigue and skin rash, there is the characteristic prolonged debilitating joint pain, lasting months or even years – which leads to infected persons' contorted posture. The name chikungunya has an origin in an African language because this mosquito-borne virus is traditionally maintained in a complex African zoonotic cycle, and was first described during a febrile illness outbreak in the province of Makonde in southern Tanzania in 1952. Workers perform anti-mosquito measures outside Sau Mau Ping Shopping Centre in Hong Kong on August 12, 2025, amid warnings of a heightened risk of possible chikungunya fever transmissions.

However, because symptomatically, chikungunya fever can be difficult to differentiate from dengue fever, the disease was previously considered and known as dengue, another febrile epidemic disease of the tropics.
