Study: ‘6G’ Radiation Boosts Brain Cell Growth in Mice_我的网站
A | The same technology that may power the next generation of mobile networks has been shown to increase the growth of brain cells in mice, according to a new study from Xian Jiaotong University in Beijing.,Radio waves in the terahertz frequency can transmit data at speeds up to 1 terabit (or 125 gigabytes) per second, it is a prime candidate for the next generation of mobile cell phone networks if it can be proven safe. By contrast, current 5G networks use millimeter waves that top out at 20 gigabits (2.5 gigabytes) per second.,But there may be another use for terahertz radio waves: treatment of neurological disorders like Alzheimer’s disease, autism, and Parkinson’s disease.,Science & Tech'Vicious Cycle' Between Alzheimer's Dementia and Daytime Napping Found by Scientists17 March, 19:05 GMT,The researchers exposed mice neurons in a petri dish to 100-microwatt pulse radiation, ranging from 0.3 terahertz to 3 terahertz. The result was that the exposed neurons grew at a rate of 150% compared to the control group. The length of connections also doubled in three days. Despite the accelerated growth, the brain cells appeared healthy.,The accelerated brain growth was not permanent; it slowed two days after exposure.,However, a 2009 study by the Russian Academy of Sciences showed that prolonged exposure to strong terahertz radiation had an adverse effect, increasing the temperature of brain cells, disturbing their development and causing dehydration of the cells which reduces their size and causes other damage.,But Li Xiaoli, the lead scientist of the new Beijing study, thinks that the negative effects of terahertz radiation could be avoided by limiting the strength and duration of exposure.,“The safety of terahertz radiation protocol is a top concern,” Li said. And while the health concerns of terahertz radiation remain, it could, Li believes, be used to treat neurological disorders.,“Abnormal neuron development and the resulting abnormal neural network structure can lead to the occurrence of various psychiatric and neurological diseases, such as Alzheimer’s disease, autism and Parkinson’s disease,” the study’s authors said.,The authors believe that a lower dose of terahertz radiation could increase the production and the activity of certain proteins responsible for brain cell growth, namely GluA1, GluN1, and SY-38. The researchers theorize that is because they contain hydrogen bonds that constantly vibrate at a frequency that falls in the terahertz range. The radio waves combine with the proteins and cause them to resonate in a “non-linear manner,” according to Li, which could “affect the shape of the proteins, and therefore the structure and function of neurons.”However, because proteins vary significantly from each other, only certain proteins are affected by the terahertz radiation at low frequencies. Li says more investigation is needed to learn how proteins react to different exposure intensities.,The study backs up another done at the Institute of Brain Science at Xian Jiaotong University that was published in June. That study found that terahertz exposure could make young mice more intelligent. There, scientists exposed mice to 90-milliwatt terahertz radiation for 20 minutes a day for three weeks. They observed that the exposed mice had more brain cells and were quicker at escaping mazes. However, for reasons that remain unclear, the same effect was not observed in older mice.。
B | 【TechWeb】7月21日消息，据彭博社报道，中国人工智能独角兽月之暗面（Moonshot AI）正加快推进香港上市计划，最快可能在未来6个月内完成首次公开募股（IPO）。 该图片疑似使用了AI生成技术，请谨慎甄别 报道称，月之暗面已正式向投资者分发股东决议文件，寻求支持其在港上市。启动通知程序表明，IPO已进入实质性筹备阶段。与此同时，公司正在完成新一轮融资，该轮融资可能使其估值超过300亿美元。 彭博社报道指出，月之暗面认为上市时机已经成熟，其年度经常性收入（ARR）在2026年6月已达到3亿美元。
C | 这一营收规模标志着公司在商业化方面取得了显著进展，为其登陆资本市场提供了业绩支撑。 在筹备上市的同时，月之暗面已开始拆除“红筹”架构，为境外上市铺平道路。红筹架构拆除通常意味着公司正在将境内权益重组至境外上市主体，是境外IPO的关键前置步骤之一。 月之暗面是中国生成式人工智能领域的头部企业之一，旗下拥有自研大语言模型kimi系列及相关产品。
D | 月之暗面7月16日上线推出的Kimi K3模型拥有 2.8 万亿参数，在 Frontend Code Arena 全球AI大模型榜单中，Kimi K3以1679分超越Claude Fable 5，位居第一。若此次IPO顺利推进，月之暗面将成为继智谱、MiniMax之后，又一家登陆港交所的中国AI大模型企业。
E | 以超过300亿美元的估值计算，其上市规模或将跻身近年来香港科技股IPO前列。 截至发稿，月之暗面方面尚未对上市传闻作出正式回应。
