Ventilatory ratio (VR) is a simple bedside index reflecting pulmonary dead space and is associated with outcomes in acute respiratory distress syndrome (ARDS). This study developed and validated separate 30-day mortality prediction models for high and low VR subgroups using multicenter critical care databases. Subgroup-specific models demonstrated superior predictive performance compared with cross-applied models, highlighting the importance of VR-based stratification for improving prognostic accuracy and supporting more individualized ARDS management strategies.

By combining observations from powerful telescopes in opposite hemispheres with state-of-the-art spectrographs, a Georgia State University astronomy graduate student has produced a landmark survey of nearby stars, identifying promising targets in the search for planets that could support life. The new research was featured at a press conference during the American Astronomical Society’s annual meeting.

Scientists at the University of Missouri have identified a small group of unusual objects in the early universe. Using NASA’s James Webb Space Telescope (JWST), Haojing Yan and his team at Mizzou’s College of Arts and Science spotted these strange objects, which seem like one galactic thing but have the unmistakable fingerprints of something else entirely.

Advanced quantum detectors designed at Texas A&M University are reinventing the search for dark matter, an unseen force that science has yet to explain.
