This is a neat series of studies that collectively suggest that the stress-susceptibility hypothesis—chronic physiological stressors can be immunocompromising and lead to more and more deadly epidemics—works, but not exactly in the way we’d expected. It is also one of very few examples where all of the links in the logic are spelled out. Congratulations Emily! (Note: Emily is now a Postdoc with Louis Rollins-Smith at Vanderbilt.)
