China Science engagement report
@ChinaScience - 2.0M followers on X
Measured over 107 original posts from a 30-day window, last computed on August 30, 2026.
Engagement
A typical post picks up 81 interactions against 2.0M followers, an engagement rate of 0.004%. Measured over 107 original posts, its engagement rate beats 33% of 3,739 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 8.4K times each, and 0.964% of those impressions turn into an interaction. That is about 0.423% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 3.7 posts a day over the last 30 days, with activity on roughly 47% of days. Most posts go out around 05:00 UTC, and Wednesday is the busiest day of the week. Of the 107 posts sampled, 100% carry an image or video and 8% link out. The account's strongest tracked post pulled 1.7K interactions, about 21x its own typical post.

Compared with accounts its own size
China Science's engagement rate beats 33% of the tracked X accounts closest to it in follower count (3,739 accounts, accounts of similar size (decile 10 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.
On engagement per impression rather than per follower it beats 55% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.
Where this sits in the catalog
At 0.004%, China Science sits above the 10th percentile of the 36,378 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.012%.

Posting timing
This account posts most often around 05:00 UTC, and Wednesday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

China has, for the first time, established a two-way laser link over a distance of more than 400,000 kilometers between Earth and the moon, achieving an uplink rate of 1.25 Mbps and a downlink rate of 100 Mbps during the experiment, which means it would take only about 12 seconds to send an 8K high-definition lunar surface image back to Earth, compared to 4 to 5 minutes via a traditional 5 Mbps microwave link. The breakthrough is expected to facilitate China's crewed lunar landings, the construction of lunar research stations, and deep-space exploration.

China has unveiled the world's first standing-position manned flying vehicle, featuring a flat, flower-shaped platform roughly 3.5 meters across, an enclosed-propeller propulsion system, and a central standing area that can accommodate pilots weighing up to 90 kg. Equipped with a dual-redundant flight control architecture and triple-redundant inertial measurement units, the eVTOL aircraft offers a flight time of up to 11 minutes with a 70-kg pilot on board.

A Chinese-led research team has developed a new type of vision chip that directly converts light into tokens, bypassing the multiple processing steps that typically consume power and slow down performance. Unlike conventional sensors, which capture light and then digitize, buffer, and transfer data before token generation, the new device serves as a "physical tokenizer," performing light-to-token conversion directly at the sensor level for vision transformers (ViTs). In tests, a system using the chip achieved 87.3% accuracy in image recognition, close to conventional software baselines, while improving energy efficiency by more than 10 times during the tokenization stage. Published in the journal Nature Sensors, the technology could provide a highly efficient, near-zero-latency vision foundation for embodied intelligence, drones and smart security, accelerating the large-scale deployment of physical AI.

China’s large unmanned aerial vehicle (UAV) Wing Loong, deployed to support rescue efforts in the mudslide-hit area of southwest China’s Xizang Autonomous Region, has logged more than 130 cumulative flight hours and facilitated over 3,900 phone calls. The UAV is equipped with mobile base stations from the country’s three major telecommunications operators, as well as a satellite communication system, providing vital emergency communications support for rescue operations.

Chinese scientists have discovered an exceptionally well-preserved pregnant specimen of a 244-million-year-old ichthyosaur Mixosaurus, containing at least 11 fetuses, in southwest China's Guizhou Province. The discovery sets a new record for the most embryos found in a Triassic ichthyosaur and reveals that high reproductive capacity in ichthyosaurs evolved earlier than previously believed.

The China-developed Thunder-RS engine recently completed a 100-second static-fire test, reaching 1,297.5 kilonewtons of thrust, or about 132.3 tonnes, during the long-duration test firing. The 130-tonne-class liquid-oxygen kerosene engine is designed for the country's large reusable commercial rocket Nebula-2.

Two Philippine surgeons performed the country's first telesurgery on Tuesday in Shanghai, China, by operating a surgical robot on a 53-year-old Filipino patient in Quezon City, the Philippines. The surgery marked a new step in China-Philippines medical cooperation, following previous collaborations in liver transplants, physician training, and cloud-based medical platforms. (file pic)

A giant 'solar power bank' hidden in Gobi Desert, NW China's Xinjiang Can a solar power plant still generate electricity after the sun goes down? In Hami, northwest China's Xinjiang Uygur Autonomous Region, rows of linear Fresnel reflectors track the sun, concentrating sunlight into thermal energy and storing it using molten salt. When night falls, this stored heat can be released to continue generating electricity, functioning just like a giant power bank for sunlight. The integrated project, combining concentrated solar power (CSP) and photovoltaic (PV) technology, has a total capacity of 1 million kilowatts (kW). It consists of a 900,000-kW PV power station and a 100,000-kW linear Fresnel molten salt CSP plant, whose solar field covers approximately 800,000 square meters. From tracking sunlight and storing heat to generating power, solar energy is transcending the boundaries of day and night in the Gobi Desert.

- What is China Science's engagement rate on X?
- China Science (@ChinaScience) has an engagement rate of 0.004%, based on the median interactions across 107 original posts from the last 30 days against 1,986,229 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.004%, China Science sits above the 10th percentile of the 36,378 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
- Does @ChinaScience have real engagement?
- Its engagement rate beats 33% of the tracked X accounts closest to it in follower count (3,739 accounts), which puts it in the middle of its size range group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
- When does @ChinaScience post?
- Most posts go out around 05:00 UTC, and Wednesday is its busiest day, at roughly 3.7 posts per day across the measured window.
