News from Science engagement report
@NewsfromScience - 766K followers on X
Measured over 88 original posts from a 30-day window, last computed on September 30, 2026.
Engagement
A typical post picks up 27 interactions against 766K followers, an engagement rate of 0.004%. Measured over 88 original posts, its engagement rate beats 22% of 20,444 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 6.5K times each, and 0.417% of those impressions turn into an interaction. That is about 0.845% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 3 posts a day over the last 30 days, with activity on roughly 53% of days. Most posts go out around 03:00 UTC, and Tuesday is the busiest day of the week. Of the 88 posts sampled, 61% carry an image or video and 100% link out. The account's strongest tracked post pulled 814 interactions, about 30x its own typical post. Recurring topics include #ai, #longreads, #sciencemagarchives.

Compared with accounts its own size
News from Science's engagement rate beats 22% of the tracked X accounts closest to it in follower count (20,444 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 27% 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%, News from Science sits below the 10th percentile of the 205,261 accounts in this comparison. That places it in the bottom 25% band, which runs below 0.024%.

Posting timing
This account posts most often around 03:00 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 | 61% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 100% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 61% 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 409 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.

Same relaxing sounds, different photo. This is what a Jurassic forest may have sounded like. By combining exquisitely preserved fossil wings with experiments on living insects, computer simulations, and machine learning, scientists have re-created what they say is a partial Middle Jurassic soundscape. If the reconstruction is correct, one of the insect calls would be the oldest known evidence of ultrasonic communication in animals—long before echolocating bats appeared.

One of the biggest downsides of upright walking in humans is the so-called obstetrical dilemma. Babies born with big brains—and thus big heads—must fit through a relatively narrow pelvis shaped for bipedal locomotion. These clashing demands, it’s been suggested, have made human births especially grueling compared with other mammals. But recent studies have questioned the simplicity of this explanation—and whether the phenomenon is even unique to humans. Now, researchers add another wrinkle to the obstetrical dilemma: fetal sex. Reviewing birth data for 140 species, a new study argues sons are more difficult to birth than daughters for many mammals, including humans and our ancient ancestors. This added risk may be offset by an evolutionary reward: Bigger male babies grow into bigger male adults, who tend to have more grandbabies, meaning more of that mother’s genes are passed down.

It was the Pompeii of the Cambrian. About 515 million years ago, a volcanic eruption blanketed shallow waters in what are today the High Atlas Mountains in Morocco. The ash entombed the invertebrates living in the soft mud of the ocean floor, and within hours reacted with chemicals in seawater and hardened into a rock that preserved a perfect mold of the creatures. After imaging those molds in 2024, researchers reported the most detailed 3D anatomy yet of trilobites, the multilegged arthropods that dominated Paleozoic seas.

Recent research finds that the ovaries of old mice become infiltrated with immune cells and may secrete immune signals into the body. The consequences of these changes aren’t clear, but a similar transformation in humans could have health implications after menopause. Learn more: https://t.co/N9dWVKeSBO

Carved into a sandstone cliff on the edge of a bygone river in the Arabian Desert, a hunter draws his bow for the kill. He is accompanied by 13 dogs, each with its own coat markings; two animals have lines running from their necks to the man's waist. The engravings likely date back more than 8000 years, making them the earliest depictions of dogs, a 2017 study revealed. And those lines are probably leashes, suggesting that humans mastered the art of training and controlling dogs thousands of years earlier than previously thought.

New research suggests a shingles vaccine may also protect against cardiovascular disease, the leading cause of death in the United States and many other countries. People who received Shingrix were less likely to suffer heart problems, at least in the short term, than people who received an older, less effective vaccine containing the live virus, according to a new study. Although the mechanisms behind the association are unclear, the authors suggest Shingrix’s ingredients could trigger temporary changes to the immune system that protect cardiovascular health.

A typical post picks up 27 interactions against 766K followers, an engagement rate of 0.004%. Measured over 88 original posts, its engagement rate beats 22% of 20,444 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 6.5K times each, and 0.417% of those impressions turn into an interaction. That is about 0.845% of the follower count, which is the gap between an audience on paper and an audience in a timeline.

- What is News from Science's engagement rate on X?
- News from Science (@NewsfromScience) has an engagement rate of 0.004%, based on the median interactions across 88 original posts from the last 30 days against 765,738 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.004%, News from Science sits below the 10th percentile of the 205,261 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 @NewsfromScience have real engagement?
- Its engagement rate beats 22% of the tracked X accounts closest to it in follower count (20,444 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 @NewsfromScience post?
- Most posts go out around 03:00 UTC, and Tuesday is its busiest day, at roughly 2.97 posts per day across the measured window.
