New strain of bacteria found on China's Tiangong space station
Chinese scientists have discovered a new microbe that developed on board the county's Tiangong space station, according to a new study.
The strain, officially named niallia tiangongensis, is a new variant of a previously known terrestrial bacteria and was found on a cabin in the space station.
The discovery was announced by researchers from the Shenzhou Space Biotechnology Group and the Beijing Institute of Spacecraft System Engineering in the peer-reviewed International Journal of Systematic and Evolutionary Microbiology.
The paper said it was 'essential' to understand the characteristics of microbes during long-term space missions to safeguard the health of astronauts and maintain the functionality of spacecraft.
The authors added that this new strain had ingenious mechanisms for adapting to the extreme space environment – a discovery that could have many real-life implications.
For instance, the strain had a better ability to combat oxidative stress – a condition that leads to cell and tissue damage due to an imbalance in the body – and reverse radiation-induced damage, according to the study.
Decoding its survival mechanism could help scientists design precise and targeted control strategies for microbes – and this could then be used in a number of sectors, including space technology, agriculture and medicine.

AI content detector: why does China dismiss it as ‘superstition tech'?
With the graduation season approaching, many Chinese universities have introduced regulations setting clear requirements for the proportion of artificial intelligence -generated content – or the 'AI rate', as it is called – in theses. Advertisement Some universities have used the AI rate as a deciding factor in whether a thesis is approved. The rule is intended to prevent academic misconduct, as educators have become increasingly concerned about the unregulated use of AI in producing scholarly literature, including data falsification and content fabrication, since the public debut of generative AI models such as ChatGPT However, an official publication of the Ministry of Science and Technology has warned that using AI content detectors to identify AI writing is essentially a form of 'technological superstition' that could cause many unintended side effects. AI detection tools could produce false results, the Science and Technology Daily said in an editorial last Tuesday, adding that some graduates had complained that content clearly written by them was labelled as AI-generated. Advertisement Even a very famous Chinese essay written 100 years ago was evaluated as more than 60 per cent AI-generated, when analysed by these tools, the article said.

Beijing academy unveils open-source ‘RoboBrain' AI model for China's humanoid robots
The Beijing Academy of Artificial Intelligence (BAAI), a non-profit research laboratory in China, launched on Friday a series of new open-source artificial intelligence (AI) models designed to be the 'brain' of robots, as the country rushes to build smarter machines. Advertisement The use of powerful AI models in China's booming robotics industry could accelerate the development and adoption of humanoids, as the sector addresses challenges such as limited model capabilities and a lack of training data, according to BAAI head Wang Zhongyuan during the institute's annual conference in Beijing. Wang described BAAI's RoboBrain 2.0 as the world's most powerful open-source AI model designed to improve various types of robots, including humanoids. The launch of this general-purpose AI model coincides with the Chinese robotics industry's rapid growth, positioning BAAI as a potential major player in the local sector. Beijing Academy of Artificial Intelligence director Wang Zhongyuan speaks at the institute's annual conference on Friday.
