How does space affect the mind? China sends ‘mini-brain' to Tiangong to find out
Tiangong space station to find out how space messes with the mind.

Researchers aboard the International Space Station have previously used brain cell cultures and early-stage brain organoids to study ageing and disorders such as Alzheimer's.
But China's experiment appears to be the first time a highly integrated brain chip featuring blood-brain barrier functions has been sent into
space
Launched on the
Tianzhou-9 cargo spacecraft on Tuesday, the experiment aims to probe the effects of microgravity on the brain and eventually help astronauts prevent dizziness, sleep problems and changes in cognitive function during long missions, according to lead scientist Qin Jianhua of the Dalian Institute of Chemical Physics.

The brain model – grown from living tissue including nerve and immune cells, capillary-like vessels and a barrier that mimics the brain's natural defences – offers more human-like data than traditional cell cultures or animal experiments, Qin told the state-run China News Service on Tuesday.

She said its three-dimensional, dynamic design also allowed real-time observation of how brain tissues behaved in orbit, making it a powerful tool for space medicine, neuroscience research and drug development.

China unveils next-gen high-speed rail tech as US puts brakes on bullet train funding
China has pulled the wraps off its next-generation high-speed rail technology as the United States revokes federal funding for California's high-speed rail project. Advertisement China's latest bullet train, the CR450 , is undergoing final performance tests to prepare it for commercial operation trials at 400km/h (250mph), the official Science and Technology Daily reported on Monday. The team surpassed the previous upper speed of 350km/h, at which high aerodynamic resistance and energy consumption levels had for decades been a technological barrier. 01:13 China unveils maglev marvel, redefining the future of high-speed rail transport China unveils maglev marvel, redefining the future of high-speed rail transport An increase in speed of 50km/h would lead to a 30 per cent rise in resistance, and greater energy consumption, a researcher at the China Academy of Railway Sciences, Shao Jun, told the newspaper. High-speed trains face 95 per cent of their resistance from air. To boost speed and save energy, the scientists adjusted the head shape of the train to reduce drag, drawing inspiration from nature to create a design based on fast-flying birds and cutting resistance by about 2.6 per cent. They then looked at the train's undercarriage, a previously overlooked area that had potential to reduce drag. Advertisement A team member had proposed an idea for a cover structure to shield the exposed areas of the bogie, creating a more complete aerodynamic shape to lower resistance, Shao said. After repeated optimisation of the cladding structure, resistance was reduced by 22 per cent. This means that even with a 50km/h increase in speed, the energy consumption of the new train remains comparable to that of the CR400 Fuxing trains operating at 350km/h.

China girl nearly dies after eating greens, laxatives for 2 weeks to fit in birthday dress
A teenage girl almost died after she ate just small portions of vegetables and laxatives for two weeks in a dangerous attempt to fit into a new birthday dress. Mei, a 16-year-old from central China's Hunan province, had to go through an emergency 12-hour medical procedure after she lapsed into a critical condition as a result of her extreme diet. For two weeks, Mei ate nothing but a small amount of vegetables and laxatives, according to the mainland news outlet Xiaoxiang Morning Herald. Mei was sent to hospital, lapsed into a critical condition, and had to endure a 12-hour emergency procedure as a result of her diet. Photo: She was sent to hospital after she suddenly lost strength in her limbs and developed shortness of breath. Examinations showed that her blood potassium levels had plunged to well below normal. This resulted in a condition called serious hypokalaemia, which is often caused by an unhealthy diet. A doctor at another hospital in Hunan, surnamed Li, said an unbalanced diet and dehydration can lower levels of potassium in the body.

Chinese kindergarten lead poisoning scandal raises fresh questions over local governance
China's worst food safety scandal in almost two decades, in which hundreds of children suffered lead poisoning , has prompted fresh questions about the quality of local governance. On Sunday, the authorities in the northwestern province of Gansu said 10 local officials were under investigation over the incident in the city of Tianshui. One political scientist, speaking on condition of anonymity, said the slow response to the incident showed how local officials 'try to avoid taking responsibility'. He added that a 'passive feedback mechanism' made it hard for the public to obtain accurate information. The investigation found that a local hospital and the provincial centre for disease control and prevention (CDC) had falsified test results. On Monday, the media outlet Caixin published a commentary questioning whether the data falsification was 'motivated by pressure or profit'.
