How do local signals regulate the activation of quiescent #StemCells upon injury? Tal Gordon &co shows how the injury response by a stem cell population in the tunicate Ciona robusta differs depending on region-specific signalling cues 🧪 #regeneration buff.ly/M0Ptzpb
In vivo imaging and whole-mount immunofluorescence of Ciona robusta following bisection, showing that only the posterior section regenerated, whereas the anterior section fails to regenerate. Ciliated cells are shown in green (acTubulin) and nuclei in blue (DAPI).

Hello people doing transgenics in any model, i have a question for you : in your experience, would you say that using codon- optimized sequences for your model’s trangenes is - compulsory - recommended - probably useless as long as all tRNAs are present in your model ? Thanks a lot for any hints !

OTD in 1925 John Scopes was found guilty of violating the Butler Act, a Tennessee statute that forbade the teaching of "any theory … that man has descended from a lower order of animals." The trial was as much an effort to bring tourist money into Dayton TN as anything else. 🐋🌱🧠🗃️🧪 #HistSTM #EvoBio
Cartoon with the city of Dayton, Tennessee, where the Scopes trail was held, represented as an organ grinder. The organ is labeled “Scopes trial,” and the grinder’s monkey is collecting dollars labeled “publicity.”

Ok, serious face. Female ejaculation ("squirting") might make it easier to get knocked up. Maybe. It's a hypothesis at this point, but in this paper, the authors outline reasonable rationale and outline some testable experiments. 🧪 Link: www.sciencedirect.com/science/arti...
