<jats:title>Converging paradigms in neurodegeneration</jats:title> <jats:p>Parkinson's disease and Alzheimer's disease are progressive neurodegenerative diseases with increasing prevalence in our aging populations. Recent evidence suggests that some of the molecular mechanisms involved in the pathology of these diseases have similarities to those observed in infectious prion diseases such as bovine spongiform encephalopathy (mad cow disease). Goedert reviews how the spread of a variety of pathological protein aggregates is involved in neurodegenerative disease.</jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" related-article-type="in-this-issue" xlink:href="10.1126/science.1255555">10.1126/science.1255555</jats:related-article> </jats:p>

<jats:p>The science of ecology is about relationships—among organisms and habitats, on all scales—and how they provide information that helps us better understand our world. In the past 100 years, the field has moved from observations to experiments to forecasting. Next week, the Ecological Society of America (ESA), the world's largest ecological society, celebrates its centennial in Baltimore, an opportunity to reflect on the field's past and future. The gathering of international scientists, policy-makers, and students will not only explore the knowledge in hand, but consider what else is needed to chart a course over the next century in which humanity sustains and even improves the relationships that underpin life on Earth.</jats:p>
