Michigan State University scientists have built tiny beating heart organoids that can be driven into atrial fibrillation with inflammation and brought back toward a steady rhythm with drugs. The model finally gives researchers human based tissue to study arrhythmias, speed drug discovery and move toward personalized heart treatments.

A Cedars-Sinai team has found that support cells called astrocytes, located far from a spinal cord injury, release a protein that helps immune cells digest fatty debris and calm inflammation. The discovery, published in Nature, reveals a hidden repair system that could lead to new treatments for spinal cord injury, stroke and multiple sclerosis.

Scientists at Northwestern University have discovered a highly toxic form of amyloid beta that appears early in Alzheimer’s disease and shown that an experimental drug, NU-9, can dramatically reduce its impact in mice. By calming overactive support cells and lowering harmful protein buildup before symptoms begin, the approach hints at a future in which high-risk patients could start treatment long before memory loss appears.
