AbstractPleural effusion is a common clinical finding with heterogeneous causes, including infection, malignancy, heart failure, tuberculosis, pulmonary embolism and systemic disease. Because patients often encounter pleural effusion as an imaging finding rather than as a diagnosis, short-video platforms may shape early understanding, anxiety and care-seeking behaviour. Evidence on the quality of this content is lacking. We conducted a cross-sectional content analysis of publicly available pleural effusion–related short videos on Douyin and Bilibili. The Mandarin search term “胸腔积液” (pleural effusion) was entered on 15 May 2026 and the first 150 results returned under each platform’s default ranking were screened.

Colorful outflows from young protostars in Orion the Hunter plunge into the thick dust of a molecular cloud in this new infrared image. A small slice of the molecular cloud known as OMC-2 in Orion explodes to life in this new JWST image. Young protostars and their powerful outflows highlight a region chock full of cold gas and dust.

College Station, TX — A recent study of construction worker use of lower-back exoskeletons found that in addition to experiencing less fatigue, workers also exhibited improved hazard recognition. Researchers at Texas A&M University asked 16 workers at a construction site in Louisiana to complete two three-hour sessions performing their normal work with and without the exoskeleton so their fatigue could be measured. The workers were also shown images of construction hazards before and after each session and asked to identify the hazards and assess the associated risks.
