Stillbirths occur at a higher rate in the U.S. than previously reported, according to a new study led by researchers at Harvard T.H. Chan School of Public Health and Mass General Brigham. The researchers also found that, while most stillbirths had at least one identified clinical risk factor, a substantial share had none, particularly those occurring at 40+ weeks gestation.
Study challenges long-held assumptions, finding late-surviving dinosaurs lived in vibrant, regionally distinct communities
In the White Mountains of New Hampshire, the streams are telling us a story about forest recovery following acid rain and logging. According to a new study in the Proceedings of the National Academy of Sciences, long-term watershed chemistry reveals that recovering forests are mining rocks for nutrients. While this leads to improved pH in nearby streams, it further depletes soils, leaving forests less resilient to future pollution. The study team analyzed more than 60 years of data from the Hubbard Brook Experimental Forest, established by the US Forest Service in the 1950s for ecological and hydrologic research.
A first-of-its-kind study explored whether more accessible technologies – foot-mounted wearable sensors and a 3D depth camera – could accurately measure how people walk, offering a practical alternative to traditional gait analysis tools. Gait, or walking pattern, is a key health indicator used to detect fall risk, monitor rehabilitation and identify early signs of conditions like Parkinson’s and Alzheimer’s. Traditional systems like the Zeno™ Walkway, the gold standard for gait analysis, are accurate but expensive, bulky and not easily used outside of lab settings.
