The blog Fight Aging! (which I highly recommend), has a nice, comprehensive year-in-review article on the progress made in 2015 towards defeating aging. It focuses a lot on progress made by the SENS Research Foundation projects, but also discusses commercial efforts like Human Longevity Inc and Calico, and the government sponsored longevity trial of metformin, along with research progress on clearing amyloid plaques for Alzheimer's disease, CRISPR technology for gene editing, cryonics, printing new organs, and more!
Well worth a read for anyone interested in lifespan extension.
P.S. Happy New Year!
