as tech landscape turns bleak
- Source Code Capital, which had invested in ByteDance and Meituan, is reportedly closing its early-stage investment programme
- Tightened regulatory scrutiny in China, a potential decoupling with the US, and slowing economic growth has put a damper on investor appetite for risks
- More than 600,000 stations added by China in three months to June, compared with 100,000 for US in 2019-2021
- 3 million mark comes six months early amid Beijing’s push to boost economy, as well as drop in costs and better tech payback, industry officials say
US continues tech crackdown.

The 4-second microgravity test harness built by CAS started trial runs recently. It is the first in Asia that is powered by an electromagnetic catapult. It can do up to 100 pulls each day and takes about 1kWh for each pull.
CAS also plans to build a larger harness of same kind for 20-second microgravity. That electromagnetic catapult will be able to pull test load up to 500kg.
该装置采用电磁抛射的方式在地面构建微重力实验环境，即采用电磁弹射系统将实验舱垂直加速到预定速度后释放，实验舱在上抛和下落阶段为科学载荷提供微重力环境，目前该装置达到了4秒微重力时间、10μg微重力水平、过载加速度不超过5g、实验间隔不大于10min的国际先进水平。与传统单程落塔、抛物线飞机等相比，装置在实验效率、实验载荷强度要求、运行成本等方面具有较大的优势。
在实验效率方面，传统落塔平均每天仅可以做2-3次实验，抛物线飞机每次可以飞行30架次以上，但实验准备周期约2-3个月。本装置可以达到每天近百次实验的频率，准备时间1-2天，极大地提高了科学实验的效率。
在实验载荷强度要求方面，传统落塔在降落回收阶段，试验舱和实验载荷要承受20g左右的冲击，很大程度上限制了常规科学仪器的使用。在本装置中，实验舱所受的电磁驱动力是全程可控的，无论是微重力、月球重力还是火星重力模拟实验，实验舱的回收加速度都可控制在3g左右，因此常规科学仪器都可以用于实验。
在运行成本方面，装置采用储能和电磁驱动技术，装置运行仅消耗电能，单次实验消耗电能仅1度左右，运行成本较低，便于开展大规模的科学实验。
充分有效的地面验证，是空间科学实验的前提和基础。地基研究能够大幅缩短实验周期、降低实验成本、提升空间实验成功率，是天基研究的重要补充手段。电磁弹射微重力实验装置有效解决了探空火箭、失重飞机、落塔等传统地基微重力设施存在的实验成本高、准备时间长、过载较大等缺点。据介绍，中国科学院空间应用工程与技术中心正在规划建设（20秒）电磁弹射微重力实验装置（重大科技基础设施），力争实现微重力时间20s、水平5ug、载荷500kg的国际领先指标，构建国际领先的微/低重力实验中心，为全世界空间科学领域的顶级科学家提供高效便捷的地基微/低重力研究平台，并为载人航天、深空探测等国家重大工程提供地基微/低重力技术验证条件。

电磁弹射微重力实验装置（4秒）启动试运行
近日，中国科学院空间应用工程与技术中心研制建设的电磁弹射微重力实验装置（4秒）启动试运行，这也是亚洲首个电磁弹射微重力实验装置。该装置采用电磁抛射的方式在地面构建微重力实验环境，即采用电磁弹射系统将实验舱垂直加速到预定速度后释放，实验舱在上抛和下落阶段为科学载荷提供微重力环境，目前该装置达到了4秒微重力时间、10μg微重力水平、过载加速度不超过5g、实验间隔不大于10min的国际先进水平。与传统单程落塔、抛物线飞机等相比，装置在实验效率、实验载荷强度要求、运行成本等方面具有较大的优势。

China has the highest proportion of rare disease drugs among all nations

China has devised a system to simplify the rare disease review process via its National Healthcare Security Administration. China’s National Medical Products Administration is usually very adept at negotiating therapy prices with manufacturers to ensure that therapies on China’s National Reimbursement Drug List are heavily discounted. This is in contrast to other markets such as the US.
China’s approval of rare disease drugs has seen an upward trend in recent years. A 2021 report found that 64 out of 74 approved orphan drugs were affordable to rural/urban residents with the National Basic Medical Insurance considered, showing an increase of 14.1% from 2017 to 2020. This comes after China established the Compendium of China’s First List of Rare Diseases (CLRD) in 2018, consisting of 121 rare diseases. Since then, authorities have the National Network to Collaborate on Diagnosis and Treatment of Rare Diseases (NCDTRD) in 2019 and more initiatives have followed. Of the four countries included in this analysis, GlobalData found that China had the highest proportion of rare disease drugs, making up 35% of its approved drugs.

To collect raindrop energy, a device called a triboelectric nanogenerator (TENG), which uses liquid-solid contact electrification, has been shown to successfully harvest the electricity from raindrops. This technology also successfully harvests energy from waves and other forms of liquid-solid triboelectric power generation. However, droplet-based TENG (D-TENGs) have a technical limitation from connecting more than one of these panels together, which reduces overall power output. A recently published paper outlines how modelling D-TENG panels after solar panel arrays makes harvesting raindrop energy more efficient, broadening its application.
The paper was published in iEnergy on June 29.
“Although D-TENGs have ultra-high instantaneous output power, it is still difficult for a single D-TENG to continuously supply power for megawatt-level electrical equipment. Therefore, it is very important to realize the simultaneous utilization of multiple D-TENGs,” said Zong Li, a professor at the Tsinghua Shenzhen International Graduate School at Tsinghua University in Shenzhen, China. “Referring to the design of solar panels in which multiple solar power generation units are connected in parallel to supply the load, we are proposing a simple and effective method for raindrop energy harvesting.”
When multiple D-TENGs are connected, there is unintended coupling capacitance between the panels’ upper electrode and lower electrode. This unintended coupling capacitance reduces the power output of the D-TENG arrays. To reduce the effect of this problem, researchers proposed bridge array generators, which use array lower electrodes to reduce the influence of the capacitance.
This diagram shows what these D-TENG panels might look like. It also illustrates how the bridge structure, when combined with the lower electrodes, can lead to improved energy storage.
Won’t be needed in another decade I reckon.
Quite an interesting . I wonder how it must have changed since 2021.
China expressed a ratio of 4.5, meaning for every 1 respondent that believes AI will ‘mostly harm’, 4.5 said AI would ‘mostly help’.
China's relative secularism and harmony with ethnic minorities has helped here:
Only 32% of those who consider religion important believe AI will help. Conversely, 48% of non-religious people believe AI will ‘mostly help’.
In 16 countries, the percentage of people who say AI will ‘mostly harm’ was higher among those who had experienced discrimination based on their race/nationality, skin color, or sex.
