Experts on aging ID a new disease that resembles Alzheimer's; Malt1 pathway poses serious risks; Stem cell research supports tissue repair R&D;

> Peter Nelson of the University of Kentucky's Sanders-Brown Center on Aging and John Crary at Mount Sinai Hospital have defined a new neurological disease that resembles Alzheimer's--a disease that continues to stump a host of drug developers. Release

> Testing the theory that blocking the Malt1 protein could be an effective pathway in fighting cancer, scientists at Technische Universität München have shown in a mouse model that such a blockade can cause serious side effects. Release

> Investigators at Harvard and MIT have demonstrated that an adult cell reprogrammed into another cell type can be durable, offering some backup to investigators working on tissue repair and diabetes. Release

> Scientists at NYU Langone Medical Center are pointing to new animal studies that back the notion that calorie restriction can arrest gene expression levels, probably slowing the steady physical erosion due to aging. Release
