Xenopus has long been used to study developmental and cell biology, and is an increasingly important model for human birth defects and disease, genomics, proteomics and toxicology. Scientists utilize Nieuwkoop and Faber's classic 'Normal Table of Xenopus laevis (Daudin)' and accompanying illustrations to enable experimental reproducibility and reuse the illustrations in new publications and teaching. However, it is no longer possible to obtain permission for these copyrighted illustrations. We present 133 new, high-quality illustrations of X. laevis development from fertilization to metamorphosis, with additional views that were not available in the original collection. All the images are available on Xenbase, the Xenopus knowledgebase (http://www.xenbase.org/entry/zahn.do), for download and reuse under an attributable, non-commercial creative commons license. Additionally, we have compiled a 'Landmarks Table' of key morphological features and marker gene expression that can be used to distinguish stages quickly and reliably (https://www.xenbase.org/entry/landmarks-table.do). This new open-access resource will facilitate Xenopus research and teaching in the decades to come.}, number={14}, journal={DEVELOPMENT}, author={Zahn, Natalya and James-Zorn, Christina and Ponferrada, Virgilio G. and Adams, Dany S. and Grzymkowski, Julia and Buchholz, Daniel R. and Nascone-Yoder, Nanette M. and Horb, Marko and Moody, Sally A. and Vize, Peter D. and et al.}, year={2022}, month={Jul} }

Indeed, anomalous laterality is associated with multiple severe birth defects. Although the events that initially orient the left-right body axis are beginning to be understood, the mechanisms that shape the asymmetries of individual organs remain less clear. Here, we summarize new evidence challenging century-old ideas about the development of stomach and intestine laterality. We compare classical and contemporary models of asymmetric gut morphogenesis and highlight key unanswered questions for future investigation.}, number={19}, journal={DEVELOPMENT}, author={Grzymkowski, Julia and Wyatt, Brent and Nascone-Yoder, Nanette}, year={2020}, month={Oct} }
