Abstract & One-Sentence Summary (sci-abstract)

When to trigger

• Significance, framing, and format are settled (do this late).
• The abstract reads like a method recap with no result.
• There is no one-sentence summary, or it restates the title.
• The abstract exceeds ~125 words or is dense with jargon/acronyms.

Two distinct artifacts Science requires

1. One-sentence summary (≤ ~125 characters)

A single declarative sentence for the table of contents and editors. It is not the title and not the first line of the abstract.

• States the finding and its general point.
• No undefined acronyms; readable by any scientist.
• Active voice. Example shape: "A single mutation rewires metabolism, explaining cold tolerance across insects."
