How wild house mice use their vocalizations, however, remains largely unresearched.

A study by Stephen Abolins, Mark Viney and colleagues of the immune ecology of wild house mice — the same species as the lab mouse — shows that their immune state is promoted by individuals» body condition and constrained by their age.

Barbara Rehermann and Stephan Rosshart first collected 800 wild house mice (Mus musculus domesticus) in the Washington, D.C., metro area, and compared their DNA and gut bacteria both with a lab mouse strain and with wild mice from all over the world.

Led by Thomas Cucchi of National Center for Scientific Research in Paris, France, and Lior Weissbrod of the University of Haifa in Israel, the study set out to explain large swings in the ratio of house mice to wild mice populations found during excavations of different prehistoric periods at an ancient Natufian hunter - gatherer site in the Jordan Valley of Israel.

Greater running distance in the 2 - to 3 - month - old mice may partially explain these data, but the solo - housed wild - type mice used to test solo - versus group - housing (Fig. 5) ran similar distances as the young mice, yet did not show any increase in brain progranulin levels.

We tested this hypothesis by housing 2 - month - old wild - type mice with or without running wheels for 3 — 4 weeks.

We housed wild - type and progranulin - insufficient mice in standard cages or cages with exercise wheels for 4 or 7.5 weeks, and then measured brain and plasma progranulin levels.

Normally, across species, larger mammals live longer than their smaller counterparts; for instance, elephants can get up to 70 years old in the wild, while house mice reach only 4 years.
