Fipronil Affects Craniofacial and Heart Development in Zebrafish Embryos (Danio rerio).

Fipronil is a broad-spectrum insecticide that has off-target effects in developing vertebrate embryos. In this study, we investigate treatment of zebrafish embryos with fipronil over the course of 5 days and examine the effects on body length, the cardiovascular system, and craniofacial morphology. We found the insecticide caused shorter body length and a decrease in eye size. By examining specific heart chamber morphology, as well as jaw angle and length, we quantified defects including enlargement of the heart and increases in jaw length and width. Further studies are needed to assess the mechanisms of fipronil's effect on vertebrate development for both environmental and human health concerns.

Finding Spirits in Spirituality: What are We Measuring in Spirituality and Health Research?

What are we asking when we ask about spirituality? When research subjects check survey boxes for "religiosity" and "spirituality" measures on health surveys, those of us who use them often assume that these responses indicate a relationship with-or reaction against-normative, conventional, Protestant-shaped religious practice and experience. We present a qualitative interview study of 13 low-income mothers with a history of depression, analyzing their descriptions of spiritual and religious coping practices. On the basis of a focused analysis of four mother's narratives, we argue that conventional survey answers may frequently hide more than they reveal about people's cultural, religious, and idiosyncratic experiences with ghosts, spirits, magic, and haunting presences that are relevant, sometimes integral, to illness and healing. We demonstrate that listening to participants' narratives challenges researchers' unconsciously normative assumptions and ought to help us reshape our understanding of the ways spirituality and religion influence health in a hyperdiverse society.
