    I had recently posted that I wished there were more epidemiological studies that tracked light exposure / time outdoors:

    The Dog Aging Project that aims at Helping Dogs Live Longer
    youtu.be/YwmkGLqi018?si=rmOcMS

    I 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.

    I wonder if thiamine deficiency increases CXCR3 expression?
