Scientific breakthroughs in brain mapping and kidney disease research

An international scientific consortium has developed the largest cellular map of a human brain region to date. By analyzing over 6.3 million cell nuclei from 1,494 individuals—ranging from young people to 108-year-olds—researchers can now observe gene activity and cellular changes with unprecedented detail. The study includes samples from healthy individuals and patients with Alzheimer's, Parkinson's, schizophrenia, bipolar disorder, and various forms of dementia.

In a separate medical investigation, researchers are studying non-traditional chronic kidney disease (CKDnt) in the Guanacaste region of Costa Rica. This variant frequently affects young, economically active individuals without histories of diabetes or hypertension, often linked to physical labor in high temperatures and dehydration. The multi-year study, funded by U.S. institutes including the NIDDK, involves participants across Costa Rica, Panama, Nicaragua, El Salvador, Guatemala, and India to identify the causes and progression of the disease.
