The simple chemical that lets queen naked mole-rats 'rule'

TL;DR — This is a Nature news article about the chemical mechanism behind naked mole-rats' unusual social hierarchy (how queens dominate colonies); it is a biology/animal-behavior story with no connection to AI or machine learning.

• Content is thin (title plus a one-line summary), so this is inferred from the metadata: it reports on a chemical signal that explains queen dominance in naked mole-rat eusocial colonies.
• Frames the finding as resolving a long-standing puzzle about these mammals' extreme social structure.
• None of the available AI topics (LLMs, Agents, Multimodal, Efficiency, Theory) apply, so it is assigned to "Other."
