39岁楚女士(化姓)是该系统首位受试者。楚女士因脑胶质瘤导致右侧肢体偏瘫,右侧手脚无力、右手几乎丧失功能。在传统康复效果不佳情况下,她于今年8月参与该系统临床应用研究,经过近2个月训练,已能完成右手指屈伸、按键等动作。
记者12日在脑机接口评估训练室看到,楚女士头戴电极帽,在脑控功能性电刺激辅助下,变换手指点按琴键,连贯弹奏出歌曲《小星星》。她还介绍,此前其右手大、小拇指无法贴合,如今已能轻松实现。
华中科技大学同济医学院附属协和医院神经外科教授姜晓兵表示,目前,国内脑机接口临床研究与应用多以腕部伸展、整手抓握等动作为主,此项系统的研发与应用将为患者精细运动功能重建带来新希望。
“单指屈伸、多指协调等精细动作,对解码及电刺激装置要求更高。”姜晓兵介绍,对此,团队通过高密度硬膜外电极植入、精细动作运动想象训练等手段,获得精细运动与大脑活动映射关系,完成非侵入式精细运动数据解码,并研发柔性矩阵式多通道功能电刺激电极,实现脑控精细运动。
目前,姜晓兵团队还在攻关精细运动解码算法,拟将相关成果拓展应用于下肢乃至全身运动的精细控制。
华中科技大学同济医学院附属协和医院是湖北首个省级脑机接口临床医学研究中心。如今,湖北脑机接口产业已初步形成“电极器件-设备研发-临床应用”的完整产业链。

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 facility in Caofeidian, Tangshan, Hebei province has entered trial production, processing waste brine at a three-to-one ratio to yield one tonne of concentrated seawater (120g/L salinity) and two tonnes of fresh water, offering a solution to global seawater discharge challenges, according to Science and Technology Daily.

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.
