#GuessThatISH returns for 2026! This full nonsense game is sure to get you smiling 😜 Can you guess what this unknown ISH probe stains (in purple) on this #zebrafish embryo? WRONG ANSWERS ONLY! Bragging rights for the winner 😎 Bonus points if you can guess the gene. Happy guessing! #ThisseThursday 🧪

The first full year of tracking research on @bsky.app
Hi, we are Altmetric, and we track how research is communicated across the web.
We now have one full calendar year of Bluesky research data and thought we'd have a looksie.

Yesterday we started #kakapo artificial insemination for the season. We do this to help maintain genetic diversity, with a potential additional benefit of improving fertility. We inseminated Esperance, who mated naturally a few nights ago. #conservation #parrots #birds

Excited to share Alison's @alisonkickuth.bsky.social paper from the lab out in @nature.com this week! We uncovered how a mechanical ratchet mechanism drives cytokinesis in early #zebrafish embryos. Read more in this thread 🧵 and at www.nature.com/articles/s41... 🤩

50 runaway sheep ram-paged through a German supermarket in rural Baa-varia, causing shear mania on Monday morning.
After breaking away from their 500-strong herd, the brazen sheep spent 20 minutes milling around in the Penny supermarket before ewe-turning and seeing themselves out.

Finally out! We studied the retinas of the longest-living vertebrate, the Greenland shark, and found that the retinas remain remarkably healthy in animals around 150 years old. What is the mechanism? It may be a highly efficient DNA repair system. Enjoy!

Not the submission process, not reviewer #2, not the editor. Writing the abstract of the paper is often a far greater challenge. And there’s one simple reason for that: most people have a hard time figuring out what’s important for the reader. I ‘ll be sharing tips in next posts - stay tuned!
