Background Barriers to cervical cancer screening are significantly higher among US rural populations. To understand these barriers and explore potential remedies, we compare perceptions of screening exam techniques, pelvic exam vs. self-sampling, and how perceptions vary by participants’ beliefs, physician characteristics, and known barriers among under-screened rural people in Michigan, United States. Methods Our mixed-method...

Large population sizes and high dispersal potential should lead to temporal genetic stability in marine species; however, the magnitude of allele frequency shifts through time have varied greatly in prior studies. We investigated temporal variation in the genetic composition of populations of two planktonic copepod species at an open ocean time series site in the North Pacific Subtropical Gyre (Station ALOHA, 22.45°N, 158°W)....
