I made a "gene info" custom GPT. Paste in a list of human gene symbols. It'll run some python code against a custom knowledge base to provide information about those genes (from RefSeq) https://chatgpt.com/g/g-677277d002608191887af1a9c0a9e832-gene-info 🧵 1/4 🧬🖥️🧪

Great bit of writing on a fascinating topic! My grandma got me a subscription to @sciam.bsky.social as a kid and reading it was one of the reasons I became a scientist. I have to admit I haven’t subscribed in awhile (not sure I can get it here in Finland) but I’m going to look into it again!
It's hard to believe there could be a giant planet in the solar system that we haven't seen. But these are exciting times! We should know within the next two years either way. www.scientificamerican.com/article/if-p...

*Of interest to fellow ancient DNA researchers* 🧪

Working on scRNA-Seq data I got excited when I attended an EMBL symposium on ancient DNA and realized some of the same visualization methods (e.g., UMAP) could be applied to ancient DNA.

Scientists, academics, researchers: We’re excited to share that @altmetric.com is now tracking mentions of your research on Bluesky! 🧪
There are already many articles for which there is more attention on Bluesky than on other comparable micro-blogging sites, meaning the academic community and the general public have clearly adopted Bluesky as one of its core places to disseminate and discuss new research.

A Place of Joy.
