> Two Chinese sites added to World Heritage List
祝賀！中國世界遺產+2

During the ongoing 46th session of UNESCO's World Heritage Committee in New Delhi, China's Badain Jaran Desert: Towers of Sand and Lakes, and the Migratory Bird Sanctuaries along the Coast of the Yellow Sea-Bohai Gulf of China (Phase II) successfully passed the review process on Friday by the World Heritage Committee to be included on the World Heritage List.
當地時間7月26日，在印度首都新德里舉行的聯合國教科文組織第46屆世界遺產大會上，中國的巴丹吉林沙漠—沙山湖泊群、黃（渤）海候鳥棲息地（第二期）成功列入《世界遺產名錄》。

The Badain Jaran Desert, located in the Inner Mongolia autonomous region, is China's third-largest desert.
巴丹吉林沙漠位于內蒙古自治區，是中國第三大沙漠。

Scattered among the towering dunes are numerous lakes, showcasing a typical and ongoing process of aeolian landform development on Earth, while also serving as a rich and diverse habitat for wildlife.
沙漠中的高聳沙丘間散布著眾多湖泊，展示了地球上典型風成地貌長期的形成過程，同時也為野生動物提供了豐富多樣的棲息環境。

Within the Badain Jaran Desert are the world's tallest fixed dunes, the most densely distributed desert lakes and a variety of wind-sculpted landforms.
在巴丹吉林沙漠中，有世界最高的固定沙丘、分布最密集的沙漠湖泊以及多樣的風蝕地貌。

The other nomination, the migratory bird sanctuaries, is a serial extension of the property of the same name that is already listed on the World Heritage List. The newly admitted five sites, namely an estuarine wetland in Chongming, Shanghai; the Yellow River estuary in Dongying, Shandong province; a wetland area in Cangzhou, Hebei province; a national-level nature reserve in Dalian, Liaoning province as well as the Yalu River estuary in Dandong, Liaoning, are part of Phase II.
黃（渤）海候鳥棲息地（第二期）是對已列入世界遺產名錄的同名遺產系列的擴展。新加入的五個棲息地是：上海崇明東灘；山東東營黃河口；河北滄州南大港；遼寧大連蛇島——老鐵山和遼寧丹東鴨綠江口，這些都屬于第二期。

China's heritage sites, including the two newly listed ones, are typical representatives of China's ecological civilization and the construction of a beautiful China, the National Forestry and Grassland Administration said. They also highlight China's strong determination and outstanding contributions to global biodiversity conservation, it added.
國家林草局指出，包括這兩處新入選的遺產地在內，中國的所有遺產地均堪稱生態文明建設和美麗中國實踐的典范，同時彰顯了中國在全球生物多樣性保護領域中的堅定決心與卓越貢獻。

> Oriental Selection stock dips 8% as top livestreaming influencer Dong Yuhui quits
董宇輝離職東方甄選！新東方股價直線跳水

Star livestreamer Dong Yuhui has decided to resign from his position as a senior partner at East Buy, also known as Oriental Selection, a subsidiary of Chinese private tutoring giant New Oriental, the company said in a filing to the Hong Kong Stock Exchange on Thursday. Dong's departure was due to his own career aspirations, commitment to other pursuits, and personal time arrangement, and has taken immediate effect, said the company.

Both sides reached a sales agreement under which Dong agreed to purchase 100 percent of equity interest in Time with Yuhui from Beijing New Oriental Xuncheng Network Technology Co, at a price of 76.58 million yuan.
董宇輝（買方）、北京新東方迅程網絡科技有限公司（賣方）及與輝同行（北京）科技有限公司（目標公司）訂立出售協議，據此，賣方同意出售，而買方同意收購目標公司的100%股權，代價為人民幣7658.55萬元。

New Oriental Education & Technology Group shares slid 8 percent after Dong's resignation, according to yicai.com.
據第一財經報道，有關董宇輝離職的公告發布后，新東方美股盤前直線跳水，一度跌超8%。

> Word of the day丨tiny solar-powered drone
每日一詞丨太陽能動力微型無人機

Chinese scientists have developed a palm-size solar-powered drone, which can fly continuously as long as it receives sunlight, according to a research article published in the journal Nature.
中國科研團隊成功研制出巴掌大小的太陽能動力微型無人機，能夠依靠自然光持續飛行。相關研究成果在國際學術期刊《自然》雜志上發表。

【知識點】
微型飛行器得益于小體積、輕質量、高機動等特點，能夠在狹小空間執行拍照、探測和運輸等特種任務，在國民經濟領域擁有廣泛應用前景。

然而此類飛行器普遍存在飛行時間短的痛點問題，尤其當重量小于10克時，其飛行時間一般不超過10分鐘。

北京航空航天大學研制的靜電飛行器“CoulombFly”（Coulomb意為庫侖，是電荷單位）翼展20cm，重4.21g。該飛行器主要由靜電發動機和超輕質高壓電源組成，具備低功耗（0.568瓦）和高升力（30.7克每瓦）優勢，首次實現了微型飛行器在純自然光供能下的起飛和持續飛行。

在本成果之前，此領域的最高水平成果是哈佛大學2019年在Nature發表的RoboBee飛行器，但仍需采用人工光源（三倍太陽光）才能實現持續飛行，而本成果僅依靠自然光即可實現持續飛行，可極大拓展此類飛行器的使用范圍，在微型飛行器的發展進程中具有里程碑意義。
