China Science engagement report
@ChinaScience - 2.0M followers on X
Measured over 136 original posts from a 30-day window, last computed on October 8, 2026.
Engagement
A typical post picks up 67 interactions against 2.0M followers, an engagement rate of 0.003%. Measured over 136 original posts, its engagement rate beats 23% of 15,519 tracked accounts of a similar size. That is a reason to look at how the audience behaves - reply depth, saves, whether the followers are recent - rather than a conclusion about it on its own. Posts are seen about 5.4K times each, and 1.23% of those impressions turn into an interaction. That is about 0.273% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 4.6 posts a day over the last 30 days, with activity on roughly 57% of days. Most posts go out around 08:00 UTC, and Tuesday is the busiest day of the week. Of the 136 posts sampled, 100% carry an image or video. The account's strongest tracked post pulled 1.7K interactions, about 25x its own typical post.

Compared with accounts its own size
China Science's engagement rate beats 23% of the tracked X accounts closest to it in follower count (15,519 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 0.003%, China Science sits above the 10th percentile of the 156,148 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.022%.

Posting timing
This account posts most often around 08:00 UTC, and Tuesday 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.

Formats this account uses
Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 100% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 4% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 100% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
- 4% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts.
- Its average post runs 578 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 15% above the same accounts' other posts.
These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

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.

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.

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.

China achieves first two-way high-speed laser communication link between Earth and Moon After more than a year of in-orbit testing, China has achieved a major breakthrough in its laser communication test between Earth and the Moon. Researchers have successfully established a two-way laser link across the roughly 400,000-kilometer distance between Earth and the Moon, marking the first time such high-speed laser communication has been conducted between the two celestial bodies. The breakthrough marks a significant step forward for China's space laser communications, extending their application from near-Earth orbit into cislunar space. Space laser communication transmits information using laser beams. Compared with conventional microwave communication, it offers several advantages, including greater bandwidth, higher data rates, improved pointing accuracy, and enhanced security. The equipment is also more compact and lighter, supporting high-speed two-way communication with flexible transmission and reception. However, longer transmission distances introduce considerable technical difficulties. https://t.co/AUsrkGpWzu

Reading these numbers
A typical post picks up 67 interactions against 2.0M followers, an engagement rate of 0.003%. Measured over 136 original posts, its engagement rate beats 23% of 15,519 tracked accounts of a similar size. That is a reason to look at how the audience behaves - reply depth, saves, whether the followers are recent - rather than a conclusion about it on its own. Posts are seen about 5.4K times each, and 1.23% of those impressions turn into an interaction. That is about 0.273% of the follower count, which is the gap between an audience on paper and an audience in a timeline.

Of the 136 posts sampled, 100% carry an image or video. The account's strongest tracked post pulled 1.7K interactions, about 25x its own typical post.
- What is China Science's engagement rate on X?
- China Science (@ChinaScience) has an engagement rate of 0.003%, based on the median interactions across 136 original posts from the last 30 days against 1,985,531 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.003%, China Science sits above the 10th percentile of the 156,148 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 23% of the tracked X accounts closest to it in follower count (15,519 accounts), which puts it in the bottom quarter for its size 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 08:00 UTC, and Tuesday is its busiest day, at roughly 4.6 posts per day across the measured window.
