This research study examines how a second pregnancy uniquely reshapes the human brain compared to a woman's first experience with motherhood. Through multimodal MRI data, scientists discovered that while both pregnancies cause significant reductions in gray matter volume, a second pregnancy specifically targets networks involved in external attention and motor control. In contrast, the first pregn...

Through this closed-loop process, the researchers identi...

This research explores the immunological environment of childhood brain tumors, which typically originate during embryonic development and often resist standard immunotherapies. By utilizing mouse models and human tissue samples, scientists identified a state of local immunosuppression where the brain appears to tolerate these tumors as "self" rather than attacking them. The study highlights how c...

Genetic mutations can alter protein behavior in various ways, including gaining new functions (neomorphs), increasing existing activity (hypermorphs), or decreasing physiological effects (hypomorphs). These researchers introduced PHNToM, a computational framework designed to classify variants of unknown functional significance (VUFS) by comparing their regulatory signatures to established mutation...
