Literature, music, and the arts can help us cope with loss by expressing our emotions in a way which seems to be universal. This paper investigates the role of co-written centenarians' autobiographies in this context. It focuses specifically on autobiographies by African American centenarians and white co-authors. The article investigates the dialogue between the centenarian and the co-author as a ritual for coming to terms with the co-author's fear of mortality. It argues that for a white readership that defines itself as secular, the black centenarian - deeply religious himself - can serve as a surrogate and a role model. Just as he assures his middle-aged, white co-author that death is not to be feared, his autobiography may offer a secular readership a model for dying.The kidney is a complex organ that performs essential functions such as blood filtration and fluid homeostasis, among others. Recent years have heralded significant advancements in our knowledge of the mechanisms that control kidney formation. Here, we provide an overview of vertebrate renal development with a focus on nephrogenesis, the process of generating the epithelialized functional units of the kidney. These steps begin with intermediate mesoderm specification and proceed all the way to the terminally differentiated nephron cell, with many detailed stages in between. The establishment of nephron architecture with proper cellular barriers is vital throughout these processes. Continuously striving to gain further insights into nephrogenesis can ultimately lead to a better understanding and potential treatments for developmental maladies such as Congenital Anomalies of the Kidney and Urinary Tract (CAKUT).Ma
