Recently, βIII spectrins have been recognized as ataxia disease genes, with the identification by Ikeda and co‐workers of pathogenic mutations in the SPTBN2 gene in three large (and mapped) SCA5 families of American and European origin.(1) With their discovery, the large “Lincoln” family has been traced back to the underlying genetic defect for the slowly progressive cerebellar ataxia. In addition, the involvement of this component of the cytoskeleton directs attention towards the possible role of organelle stability during neurodegeneration. The findings (...) suggest that the mechanical properties of neurons and their dynamics may be as important as altered Ca2+ homeostasis, transcriptional dysregulation, and impaired protein degradation in neurodegeneration conditions.

Third World debt, seen as distant from the realm of international affairs and ethics, is often subject to abstract economic analysis. Bauer argues that the way in which debt is addressed by debtors and lenders is heavily politicized and should be subjected to ethical scrutiny.
