China's 'Artificial Sun' Breaks Record, Sustains Plasma for 1,000 Seconds

CNChina|

China has made significant strides in nuclear fusion energy with its Experimental Advanced Superconducting Tokamak (EAST), known as the 'artificial sun.' The reactor recently set a new record by sustaining plasma for 1,000 seconds, surpassing its previous record of 403 seconds achieved in 2023. This groundbreaking experiment is a vital step towards creating a sustainable and clean energy source.

Scientists have long aimed to harness the power of nuclear fusion, which involves merging atomic nuclei to release vast amounts of energy, similar to the process that fuels the sun. Achieving stable operation at temperatures exceeding 100 million degrees Celsius has presented numerous challenges, making the recent success a noteworthy milestone.

Song Yuntao, director of the Institute of Plasma Physics at the Chinese Academy of Sciences, emphasized that achieving stable operation over extended periods is crucial for the development of practical fusion energy solutions for future power plants. While ignition—the point at which fusion reactions are self-sustaining—has yet to be reached, sustaining plasma for 1,000 seconds demonstrates substantial progress.

China's EAST reactor has been operational since 2006, completing many tests and leading to the construction of new experimental facilities in Anhui Province aimed at advancing fusion research. As nuclear fusion is considered the holy grail of energy due to its potential for clean, near-unlimited power, the international scientific community is hopeful for future collaborations to bring fusion energy into practical use.

China Claims Development of Hypersonic Missiles Capable of Global Strikes in 30 Minutes

Chinese scientists have reportedly developed hypersonic missiles that can strike any location on Earth within 30 minutes, based on a recent publication in the academic journal Acta Aeronautica et Astronautica Sinica. These missiles are equipped with a re-entry glide vehicle (RGV) capable of traveling at speeds up to Mach 20, or approximately 13,000 kilometers per hour, allowing for rapid changes in direction that complicate detection by traditional defense systems. The advancement follows India's successful Operation Sindoor, where the BrahMos missile penetrated Pakistani defense systems, highlighting the evolving dynamics in global defense technology. Major powers, including the United States and Britain, are also advancing in hypersonic technology, with an expected readiness date for their joint project in 2030. India is progressing in this domain as well, having tested its own hypersonic missile technology and actively developing the BrahMos-2 missile. Experts assert that despite having advanced air defense systems, India must bolster its capabilities to address the challenges posed by these emerging hypersonic threats.

Sudden Storm Capsizes Tourist Boats in China, Leaving 10 Dead

A sudden storm caused four tourist boats to capsize in Guizhou province, China, on May 5, resulting in the tragic deaths of ten people, according to state broadcaster CCTV. Over 80 individuals were thrown into the Wu River as strong winds and hail struck the scenic area during a busy national holiday. Initial reports mentioned only two boats capsizing, but officials later confirmed that four were involved, with two containing no passengers. The seven crew members on these boats managed to save themselves. Approximately 70 people were treated for injuries, most of which were minor. Chinese President Xi Jinping has ordered extensive rescue efforts and emphasized the need for improved safety precautions at tourist sites following a series of accidents. Eyewitnesses noted that while some managed to swim to safety, the storm appeared abruptly, shrouding the river in mist. The boats involved had a capacity of around 40 passengers each and were reportedly not overloaded at the time of the incident.

China’s Global Campaign of Dissent Suppression Exposed

A recent investigation reveals China's extensive and systematic efforts to suppress dissent among its diaspora, employing tactics of transnational repression. Interviews conducted by the International Consortium of Investigative Journalists (ICIJ) with over 100 victims across 23 countries highlight the extensive extent of these efforts, which reportedly include surveillance, coercion of relatives, and cyber harassment. Jiang Shengda, a prominent activist based in France, described receiving threats against his family in China aimed at silencing his protests against President Xi Jinping’s government. China’s Ministry of Foreign Affairs denied any allegations of transnational repression, asserting such claims are unfounded “fabrications” meant to slander the nation. Conversely, experts describe these methods, including intimidation, hacking, and economic sanctions, as an extension of the Chinese Communist Party's repressive strategies. The findings point to a greater challenge for democratic nations, which often lack the requisite tools and understanding to combat these sophisticated tactics effectively. As activists like Jiang speak out in the face of threats, the international community grapples with the ramifications of China's expanding influence on global freedoms.
