1. [China-US] Xie Feng, China's new ambassador to the US: I am here to defend China's interests and to promote exchanges and cooperation between China and the US.

2. [Local] The Nanning Municipal People's Government website issued an announcement that the Nanning Municipal People's Government has decided that Nanning Huipo Parking Service Co., Ltd. will cease operations, suspend business for rectification, and undergo an audit. Nanning Public Transportation Group Co., Ltd. will take over the operation and management of urban road parking spaces.

3. [Enterprise] To combat deepfakes, Microsoft will add watermarks to AI-generated content. It is taking proactive measures to ensure that AI art generated by its programs can be identified, allowing anyone to recognize whether images or video clips generated by Bing Image Creator and Microsoft Designer are AI-generated. Microsoft stated that this technology uses cryptographic methods to mark and sign AI-generated content and attach metadata about its origin. Microsoft said that this feature will apply to the "main image and video formats" supported by its two AI content generation programs, but did not specify which formats are supported.

4. [Industry] Bing's surpassing of Baidu in Chinese market share may be a mistake. In April 2023, Microsoft Bing surpassed Baidu in desktop search market share in China, sparking heated online discussions. In response, Aodhan, CEO of Statcounter, told a reporter from the Science and Technology Innovation Board Daily, "There are anomalies in the statistics of search engine market share in China, and we are investigating."

5. [Taiwan] On May 22, the World Health Assembly again rejected proposals related to Taiwan.

6. [Industry] Xiaoice launched the "GPT Clone Project," initially limiting it to 300 spots. Data collection takes as little as three minutes to create an AI clone based on a person's personality, skills, voice, and appearance. A platform will also be provided for individuals to offer their verified clones to their audience, either paid or unpaid. Xiaoice said that as the project progresses, it will gradually relax restrictions on the number of people and quotas. The plan is to expand the scale of GPT clones to 100,000 by the end of the year.

7. [Ukraine] Head of Ukraine's Main Intelligence Directorate: The counteroffensive will begin soon. The most basic necessary weapons reserves are already in place.

8. [Russia] Russian Deputy Prime Minister: Russia's energy supply to China increased by 40% in 2023.

9. [Russia] Gazprom announced its annual net profit for this fiscal year at 1.23 trillion rubles, a 41% decrease year-on-year. After the board of directors announced its decision not to pay dividends to shareholders in 2022, the stock price fell 4% on the Moscow Exchange.

10. [Scientific Research] A new type of nanosheet can quickly "target" and attack tumor cells. After 5 minutes of low-frequency ultrasound on breast cancer mice, the "armor" covering the tumor site began to activate, forming a powerful built-in electric field, catalyzing the production of active oxygen that clears the tumor in situ. After 2 hours, the tumor cells began to die... This experiment, completed by the Inorganic Functional Materials Application Basic Research Team of the School of Materials Science and Chemical Engineering at Harbin Engineering University, reveals a new mechanism for precise and efficient "piezoelectric catalysis" cancer treatment. Compared with the treatment method using highly toxic chemotherapeutic drugs, this method is highly efficient, specific, and safe, using a more stable redox reaction for dynamic control, providing new ideas for the design of piezoelectric material targeted tumor therapy. The relevant results were published in the journal Advanced Materials.
