Situated in the Caofeidian industrial zone of Tangshan, Hebei province, the facility recently entered its trial production stage, the state-run Science and Technology Daily reported last month.
This technology provides a viable pathway to solving the global challenge of discharging concentrated seawater into the sea, according to the report.
The facility processes waste brine at a three-to-one ratio, yielding 1 tonne of refined concentrated seawater – with a salinity of 120 grams per litre – alongside 2 tonnes of fresh water.

Wu Jianfu, director of the Earthquake Forecasting and Forecasting Center of the Central Meteorological Administration, said that about 9 seconds after the Hualien magnitude 7.2 earthquake occurred on April 3, 2024, the Meteorological Administration issued the first wave of national warnings, using the difference in the transmission speed of P waves and S waves to warn before the arrival of strong shock waves. Although response time can be obtained from seconds to tens of seconds in areas far away from the epicenter, there are still early warning blind spots near the epicenter. The Meteorological Administration has adjusted the conditions for issuing warnings and expanded the coverage of warnings.

A team from the Department of Chemical Engineering at the National Taiwan University of Science and Technology developed an all-solid-state lithium-ion battery. After a puncture and cutting test, there was almost no significant temperature rise. The connected LED bulb continued to glow, significantly reducing the risk of thermal runaway. The team from the Institute of Applied Science and Technology used gas separation membrane technology to improve the efficiency of carbon dioxide capture and hydrogen purification. The two teams won the runner-up in the energy group and the sustainability group respectively in the 2026 Net Zero Tech international competition, with each receiving a prize of NT$600,000.

Academia Sinica has joined hands with National Taiwan University and other institutions to promote the "Taiwan Bridge Project" and invited 31 Nobel Prize winners to visit Taiwan from November last year to April this year. This project not only deepens academic exchanges, but also emphasizes humanistic care, inspires researchers through close interactions, and promotes long-term cooperation with international research institutions such as Taiwan and the UK.

Fields medallist Shing-Tung Yau has launched the Yau Laboratory Alliance for Mathematics and Artificial Intelligence in Beijing, uniting eight institutions to accelerate AI integration in mathematical research and address the gap with the United States.

The Dunhuang Academy recently demonstrated the latest progress in the protection and restoration of the Mogao Grottoes murals and sculptures. Scientific researchers use nano sponges and digital technology to overcome problems such as smoke control. The young generation of restorers are inheriting traditional skills while protecting millennium cultural heritage.
The results released by the third comprehensive scientific survey of Xinjiang show that in the past 30 years, Xinjiang's climate has become warmer and wetter, the amount of water resources has increased, desertified land has shrunk, and the area of oasis has expanded. Scientific research has made important progress in biodiversity, mineral resources and cross-border ecological protection, and the results have benefited countries along the “Belt and Road”.
