摘要：

New and archival observations of the low-metallicity dwarf irregular galaxy WLM show that it contains carbon monoxide, the main tracer for interstellar clouds capable of forming stars, and suggest that in small galaxies both star-forming cores and carbon monoxide become increasingly rare as the metallicity decreases.
