4 h. ago How Chinese scientists cracked the secret of organ regeneration

Chinese scientists who successfully restored damaged outer ears in mice said their findings proved the existence of a genetic switch for organ regeneration, which meant it might also be present in other organs. While the scientific journey to achieving organ regeneration in humans remains long and challenging, the study, published in the peer-reviewed journal Science, has offered the researchers hope. Last week, co-corresponding authors Wang Wei and Deng Ziqing published their findings that a...

Chinese scientists have, for the first time, cultivated a beating heart structure with human cells in a pig embryo, reporting that the heart continued to beat for 21 days unaided. The study, led by Lai Liangxue’s team from the Guangzhou Institutes of Biomedicine and Health under the Chinese Academy of Sciences, was announced at the International Society for Stem Cell Research’s annual meeting in Hong Kong on June 12. Previously, the team had cultivated human kidneys in pigs for up to 28...

Chinese scientists have developed a new blockchain storage technology that they say can resist attacks from quantum computers. Blockchain technology – which provides a shared, decentralised digital ledger that stores tamper-proof records – has shown revolutionary potential in areas like financial services and supply chain management. Usually, blockchains use specialised encryption algorithms to verify each transaction, ensure the ledger’s security, and provide transparent access to...

In the first high-precision satellite mapping of carbon dioxide emissions from large international coal power plants, Chinese scientists have found that existing databases are underestimating discharges from facilities across the globe. They include China’s Tuoketuo – the largest coal-fired power station in the world – and Alabama’s James H. Miller Jnr facility, the most polluting plant in the United States, according to a paper published on June 9 by the peer-reviewed Journal of Cleaner...

7 d. ago Mammals could regenerate tissue by turning on ‘genetic switch’: Chinese team

Chinese scientists say they have restored the damaged outer ear in mice, a mammal that lacks natural regenerative abilities. The researchers said the pathway they identified could be applied to different tissue types and play a significant role in advancing regeneration in vertebrates. The team found that a mouse’s failure to regenerate stemmed from an inability to produce sufficient retinoic acid, a derivative of vitamin A that regulates what cell type emerges during a cell’s development and...

The Chinese navy’s chief of staff and a top nuclear scientist have been stripped of their membership of the country’s legislature. Vice Admiral Li Hanjun, chief of staff of the People’s Liberation Army Navy, and Liu Shipeng, deputy chief engineer at China National Nuclear Corporation, have been expelled from the National People’s Congress (NPC). Li is the latest of a string of PLA generals and a handful of defence industry executives to have implicated in a sweeping crackdown in the military. In...

Scientists in China have developed the world’s first 3D model of early mouse embryos, revealing how life forms in its initial stages at single-cell resolution. The team said this was a first step towards a deeper understanding of how diseases such as congenital heart defects develop, while providing insights into organ regeneration and cancer treatment. “Early organogenesis is a crucial stage in embryonic development, characterised by extensive cell fate specification to initiate organ formation...

The American economy has outperformed others by relying on a sort of secret, magic “sauce”, but Washington’s tariff and immigration policies are threatening to shift the outlook, according to leading US scholars attending the “Summer Davos” in China. At the gathering, formally known as the World Economic Forum’s 16th Annual Meeting of the New Champions, they collectively took stock of the US economy and debated whether it would be China or the US that most advances the frontier of tech and...

Failing to address the risks posed by deceptive, out-of-control artificial intelligence (AI) could leave humans facing “existential risks”, a leading Chinese computer scientist and AI expert has warned. Andrew Yao Chi-chih, dean of Tsinghua University’s College of AI, told an on-campus forum on Monday that the industry had seen multiple instances of deceptive behaviour by large language models (LLMs). “Once large models become sufficiently intelligent, they will deceive people,” Yao said at the...

Researchers in China said they have found the first evidence that subatomic particles from cosmic rays may be affecting the efficiency of widely used error correction techniques that are an essential element of fault-tolerant quantum computing. The scientists monitored superconducting quantum chips alongside fundamental subatomic particles – called muons – produced by cosmic rays, as well as gamma ray-induced particle disturbances known as quasiparticle bursts. “We directly observed...

Advances in the transplant of cells into the spleen could transform one of the body’s “expendable” organs into a hub for treating diabetes, two Chinese studies have found. Research published last month by scientists at Nanjing University and other institutes found that “shielding” islet cells could improve their survival after being transplanted into the spleen to treat type 1 diabetes. They also found that the spleen – a more promising long-term survival site than the conventionally used liver...
