A man with diabetes is making his own insulin after cell transplant. A 42-year-old man with type 1 diabetes has become the first patient in the world to naturally produce insulin again after receiving gene-edited pancreatic cells. Using CRISPR-Cas12b technology, scientists reprogrammed donor islet cells to evade immune system attacks that normally destroy transplanted tissue in diabetics. This breakthrough eliminates the need for lifelong immunosuppressive drugs, which often carry severe side effects. The patient received nearly 80 million of these “hypoimmune” cells, which survived and thrived in his body. Four months later, doctors confirmed the cells were producing insulin by detecting C-peptide spikes after meals. While still in early trials, this marks a potential revolution in diabetes care, showing that the disease could one day be managed without daily insulin injections. If scaled, it could transform the lives of millions living with type 1 diabetes worldwide.

12 patients with metastatic cancer. Melanoma, breast, kidney. Doctors injected a re-engineered antibody (CD40 agonist) into a single tumor. Not IV. Not systemic. One local shot. The result: tumors shrank across the entire body, including at sites that were never touched. 2 of 12 patients hit complete remission. The injected tumors didn’t just shrink. They were replaced by organized immune tissue, tertiary lymphoid structures, essentially training camps for cancer-killing T cells. Zero severe side effects. The concept: instead of flooding the body with immunotherapy and hoping it finds the cancer, turn one tumor into a vaccine against itself. Train the immune system locally. Let it hunt globally. Nearly 200 patients now in expanded trials across bladder, prostate, and brain cancers. Published in @Cancer_Cell by Jeffrey Ravetch’s lab at @RockefellerUniv and @MSKCancerCenter

La universidad medieval evaluaba con exámenes orales. Evaluar es exigir que el conocimiento se interiorice. Si la IA reduce el esfuerzo, la universidad debe reintroducirlo de otra forma. La IA está forzando otro cambio: menos tareas en casa, más interacción directa, más conversación socrática. The New York Times: Si la escritura “aceptable” se automatiza, la educación superior debe centrarse en pensamiento crítico, identidad intelectual y evaluación relacional. nytimes.com/es/2025/08/27/…
