A research paper by scientists from Beihang University proposed a machine learning (ML)-driven cerebral blood flow (CBF) prediction model, featuring multimodal imaging data integration and an interactive web application to address the challenge of quantitative CBF assessment during long-duration spaceflight.

Immune cells called B cells make antibodies that fight off invading bacteria, viruses and other foreign substances. During their preparation for this battle, B cells transiently revert to a more flexible, or plastic, stem-cell-like state in the lymph nodes, according to a new preclinical study from Weill Cornell Medicine investigators. The results could help explain how many lymphomas develop from mature B cells rather than from stem cells, as many other cancers do, and guide researchers in developing better treatments.
