The Dog Aging Project that aims at Helping Dogs Live Longer
https://youtu.be/YwmkGLqi018?si=rmOcMSpsWsWUCD-HI was really disappointed about the NIH funding cut - this project is important for both dog and human health. As Dr Kaeberlein points out, it's also great in terms of public relations for geoscience and science in general.
~
It's an open science project - the data are available to qualified researchers.
