Government Office for Science engagement report
@uksciencechief - 165K followers on X
Measured over 1 original post from a 30-day window, last computed on October 23, 2026.
Engagement
Early reading. We have captured 1 original post for this account, below the 8 we require before treating a median as settled. The numbers above describe what we have seen so far, not a finished profile of the account.
A typical post picks up 5 interactions against 165K followers, an engagement rate of 0.003%. Posts are seen about 3.0K times each, and 0.167% of those impressions turn into an interaction. That is about 1.82% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.03 posts a day over the last 30 days, though only 3% of days saw any activity at all. Most posts go out around 10:00 UTC, and Wednesday is the busiest day of the week. Of the 1 posts sampled, 100% carry an image or video and 100% link out. The account's strongest tracked post pulled 6.4K interactions, about 1281x its own typical post. Only 1 original post have been captured so far, fewer than the 8 posts we want behind a median before treating it as settled. Read the figures above as an early measurement of this account, not as a finished profile of it.

Posting timing
This account posts most often around 10:00 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.

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 | 100% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | no effect | -2% to -1% | 42K |
- 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.
- 100% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts, so a large share of this account's output sits in the weakest bucket we measure.
- Its average post runs 223 characters, which falls in the 180 - 280 characters band. Across the catalog, posts of 180 to 280 characters match the same accounts' other posts almost exactly.
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.

Susumu Kitagawa, Richard Robson and Omar M. Yaghi have been awarded the 2025 #NobelPrize in Chemistry for the development of a new type of molecular architecture. In 1989, chemistry laureate Richard Robson tested utilising the inherent properties of atoms in a new way. He combined positively charged copper ions with a four-armed molecule; this had a chemical group that was attracted to copper ions at the end of each arm. When they were combined, they bonded to form a well-ordered, spacious crystal. It was like a diamond filled with innumerable cavities.

“I can’t imagine accepting the prize without them.” In this interview shortly after the prize announcement, new physics laureate John Clarke is still stunned by the news. He praises his co-laureates John Martinis and Michel Devoret, who he worked together with at a lab in Berkeley, California, some 40 years ago. Clarke recollects the many discussions and extensive work that eventually led to their Nobel Prize-awarded discoveries. “It took us a long time to get all of this worked out. None of this work would have happened without the two of them.” Listen to the interview here. #NobelPrize

We’re excited to introduce our new CEO: Kathleen Fisher. ARIA is at an inflection point. We’re moving from launching ambitious research to driving it forward. Kathleen is the ideal leader to scale our work. She led DARPA’s HACMS programme – successfully defending a helicopter from elite hackers mid-flight. It was later named DARPA’s most influential of the past decade. This new chapter is only possible thanks to our founding CEO, @ilangur, who turned ARIA from a concept into a reality. We’re deeply grateful for his stewardship. He remains as CEO until Kathleen joins in February 2026. Read more: https://t.co/sVfkA8TNwU

- What is Government Office for Science's engagement rate on X?
- Government Office for Science (@uksciencechief) has an engagement rate of 0.003%, based on the median interactions across 1 original posts from the last 30 days against 164,586 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
