Art class today. The theme was underwater, so I couldnt resist painting my model organism #Xenopus laevis (African clawed frog). This is done in encaustics, which is a mixture of beeswax and resin 🐸 #Art #SciArt 🧪

1) By using a D-amino acid oxidase (DAAO), iAPEX omits the requirement of external H2O2 addition and therefore reduces toxicity and allows in vivo applications, which our fantastic collaborators @kerstinfeistel.bsky.social and @walenteklab.bsky.social could show in developing #Xenopus embryos.

We are looking for: PhD Student (starting as Research Assistant) and Postdoctoral Researcher in Stem Cell Biology and Mechanobiology. Please RT💕 🔗 About our lab: renew.science/principal_in... 🎓 PhD position: jobportal.ku.dk/phd/?show=15... 🧪 Postdoc position: jobportal.ku.dk/videnskabeli...

Ran et al. generated a retinal regeneration model and a tumor model using targeted integration in X. tropicalis (PNAS). Kagawa et al. provide a step-by-step protocol for knock-in targeted integration in X. laevis (DGD). www.xenbase.org/xenbase/doNe... #science #devbio #xenopus #frogs

NIH needs to hear from us about why in vivo work with animal models is essential for the advancement of biomedical research! Add your comments at the link below (scroll down to comment box): www.fda.gov/news-events/...

Last chance to tell the NIH if you think animal models are important for biomedical research! 👇👇👇👇

40 years ago today -They WERE the Champions and they totally Rocked us. www.openculture.com/2025/07/watc...

The NIH is asking scientists and the public to comment on plans to drastically limit animal model research. If you think animal models remain important tools for basic and clinical research tell them! Click the link below and scroll down to send your comments! www.fda.gov/news-events/...

Birth defects kill twice as many children as cancer. Animal model are crucial; no stem-cell or computer models can yet recapitulate the embryo's complexity. If you support birth defects research tell NIH that animal models are important! Click & scroll below to comment. tinyurl.com/mr3he6bx

Issue 5 is all yours to explore! On the cover: Henrike Berns et al. show a two-headed Xenopus laevis embryo stained for a subset of hindbrain spinal-cord projecting neurons (green), filamentous actin (pink) and nuclei (blue). bit.ly/4lktg1z

Xenopus frog study examines gene variant found in a child with mirror-image organ placement & other developmental defects, reveals role of Wnt11 📷 Henrike Berns et al, M. Schmidts & @walenteklab.bsky.social Uni of Freiburg in & on cover of @dmmjournal.bsky.social ➡️ bpod.org.uk/archive/2025...

Congrats to Henrike! Not only she has published her WNT11 study in DMM, but she also got the cover and now was selected for the Biomedical picture of the day! bpod.org.uk 👏👏👏 the image was taken at the 2024 @cshlxeno course btw. #xenopus 👊
