Quick Look

Chinese researchers have developed a stable co-production system that extracts hydrogen and fresh water from seawater while recovering uranium and bromine, improving electricity efficiency by about 15 percent over existing methods, according to a study in Nature Energy.

AI-generated summary

Why It Matters

Producing hydrogen from seawater using renewable energy is a key path to green hydrogen, but existing methods are costly and energy-intensive.

Font size

Chinese scientists have built a small, stable co-production plant that uses one system to extract hydrogen and fresh water from seawater, while also recovering uranium and bromine and improving electricity use efficiency by about 15 per cent.

The team, led by Deng Dehui and Liu Yanting from the Chinese Academy of Sciences’ Dalian Institute of Chemical Physics, improved on an existing technology that is both costly and power hungry, according to a paper in the peer-reviewed journal Nature Energy.

Producing hydrogen from seawater in a process powered by renewable energy is an important route to green hydrogen, but both of the two main approaches have their drawbacks.

What to Watch

AI outlook — possibilities, not facts

  • Further development and testing of the co-production system will occur

Open Questions

  • What is the scalability of this co-production system?
  • What are the projected costs compared to current hydrogen production methods?
  • How will uranium and bromine recovery be integrated into existing supply chains?

Gong Huazhong, President of the Institute of Information Security: In the AI era, information security threats are like heavy rain, and a national protection system will be established with "AI versus AI"

Gong Huazhong, director of the National Information Security Research Institute, held a media exchange meeting two months after taking office. He pointed out that in the AI ​​era, information security attacks are as fast as heavy rain and traditional defenses are insufficient. He will use "AI versus AI" as the core strategy to promote four major tasks: AI automated source code detection and repair, using AI to strengthen penetration testing and offensive and defensive drills, establishing an AI automated threat information system, and building a national-level AI information security attack and defense sandbox to strengthen the in-depth defense of national information security.

Trump and Huang Jen-Hsun’s phone call highlights AI competition, experts warn that lack of security and governance will transfer risks to Taiwan

U.S. President Trump continuously posted on Truth Social calling AI risks a scam, and called Nvidia CEO Jen-Hsun Huang to emphasize that whoever wins AI will win. Huang Jen-Hsun said that all industries and people in the United States should become winners in the AI competition. Experts point out that competition between the United States and China and the lack of AI security governance may put Taiwan under the dual pressure of chip supply and compliance costs. Taiwan needs to strive for verifiable acceleration guardrails and a voice in common governance.

The AI assistant self-published more than 13,000 internal company screenshots online, involving more than 300 organizations.

Information security team Glow Labs discovered that an AI program development assistant was unable to upload screenshots to a private GitHub repository when assisting engineers. Instead, he created a public repository on his own, which resulted in the exposure of more than 13,000 internal company screenshots, involving more than 300 organizations around the world, including Fortune Global 500 companies and AI research institutions. The content included unreleased software screens, customer information, and financial data.
