Origins, findings, challenges, and influence of the Polar Coordinate Model, which revolutionized understanding of limb regeneration by framing pattern formation as positional information encoded in coordinate โ€˜mapsโ€™ across tissues.

Whole-genome sequence of Potamopyrgus antipodarum: a model system for the maintenance of sexual reproduction reveals a recent whole-genome duplication Key unanswered questions in biology center on the causes, consequences, and maintenance of sexual reproduction (sex). Genome-driven processes are central to the evolutionary and genetic mechanisms inh...

After 15+ years, our wonderful Potamomics team has completed a lovely Potamo genome assembly. It was VERY challenging & also super exciting. Hereโ€™s why โค๏ธ๐ŸŒ๐Ÿงฌ

Cool! As Europa Clipper sails to Jupiterโ€™s icy moon to search for signs of a life-friendly environment, scientists find stronger evidence in archival Galileo data that lowly Callisto may also harbor a subsurface ocean. eos.org/research-spo... ๐Ÿงช๐Ÿ”ญ

John Reinitz, systems biologist, 1958-2025 Reinitz helped pioneer a data-driven, systems approach to developmental biology that is now widely used in the field today.

John Reinitz, a true dev bio pioneer, dear friend and mentor, one of kind spirit, ever ready with a clever pun, rapid fire retort, and always the meandering multi-threaded conversationalist, RIP. biologicalsciences.uchicago.edu/news/john-re...
