一 | 北京时间1月16日消息，我们的太阳系有一颗恒星和八颗行星。 (ECNS) -- A medical team in Shanxi Province on Wednesday performed the region's first invasive brain‑computer interface (BCI) implant surgery, opening up new possibilities for restoring mobility in patients with spinal cord injuries. The surgery was performed by a team led by Guo Geng, director of the BCI Clinical Research Center at the First Hospital of Shanxi Medical University. The system enables the patient, who has high-level paralysis for three years, to control external devices through brain signals including computers, smart home equipment. It can also enable the control of a pneumatic glove to perform daily tasks such as drinking and eating, and may eventually help patients regain independent hand movement. Stable collection, transmission, and decoding of neural signals have been observed since a flexible cortical electrode, measuring just 10 micrometers thick, was placed on the target brain area. According to Guo, the system is designed for full internal implantation, which reduces infection risk and allows patients to use it more conveniently in everyday life. Its ultra-flexible electrodes capture brain signals while minimizing damage to surrounding tissue. The system also integrates wireless charging and Bluetooth data transmission, with a response delay as low as 50 milliseconds. The surgery marks a milestone for invasive BCI research in Shanxi and provides new hope for millions of people with spinal cord injuries and paralysis. (By Intern Liu Shuangjing, Zhang Dongfang) 。

二 | 但其他星系可能远不止这些，而且会有两三颗恒星围绕彼此运行。一组天文学家发现了一个由四颗恒星组成的星系，它隐藏在146光年之外。这个星系被命名为HD98800。天文学家利用智利的阿塔卡马大毫米阵列射电望远镜发现了它。射电望远镜是发现这个星系的关键，因为这些恒星被原行星盘所包围。据报道，最初的行星盘是指在行星形成之前出现在早期星系中的尘埃和气体环。最终，尘埃和气体会坍缩成行星，但在此之前，圆盘将阻止大部分光从星系中逃逸。然而，无线电波可以穿透灰尘。

三 | 基于这一原理，科学家们利用射电望远镜在尘埃中发现了四颗独立的恒星。这四颗恒星形成了两对双星，一对在银河系的中心，另一对在数十亿英里外的轨道上。根据天文学家的说法，外对命名为aa和ab，而中心对命名为ba和bb。由四颗恒星组成的星系本身很奇怪，但真正让这个星系奇怪的是原行星盘。在大多数系统中，原始的行星盘与主星对齐。例如，在我们自己的太阳系中，所有的行星和小行星都在与太阳大致相同的平面上运动。

四 | HD98800的情况并非如此，它是一个由尘埃和气体组成的原行星盘，与中央恒星平面成直角。恒星系是人类发现的第一个具有这种垂直圆盘的双星系统，这表明宇宙中有许多未知现象等待发现。此外，最初的行星盘通常最终形成行星，这意味着以各种奇怪的角度围绕二元系运行的行星可能会出现。我们通常不从这些奇怪的角度寻找行星，因此这表明人类可以在未来探索这些行星。
