We identify evidence of off-target probe binding in the 10x Genomics #Xenium v1 Human Breast Gene Expression Panel, compromising the accuracy of resulting #singlecell #spatialtranscriptomics See our preprint for more details: biorxiv.org/content/10.110… #AcademicTwitter 🧵👇 1/n

I use #ggplot #gganimate #Rstats to visualize spatiotemporal trends in public ICE detention data Watch ICE detention increase over time: more detainees (bigger dots), more non-criminals (blue → red), and more jails popping up inland in 2025 Code #gist: gist.github.com/JEFworks/899a1…

I visualize trends in #ICE #immigration arrests and encounters over time and across select US cities using public data from deportationdata.org/data/ice.html Here is the #RStats #ggplot code so you can visualize the #dataviz trends in your own city: gist.github.com/JEFworks/0c76f… #codetutorial

I received some old microscopy slides from 1800s, when at-home microscopes made it possible to look at hidden worlds of diatoms, polycystina + other teeny tiny things. I made this website so people today can take a look too: microspeci.men Enjoy! #scienceisforeveryone

How it started vs. How it's going #Tenured Grateful to all those who've been a part of this journey so far. The fun is just getting started 💪 Curious to find out what this privilege of tenure can enable. Let's put it to the test. Feel free to share ideas 😉 #AcademicTwitter

I received this Victorian (~1850s) #microscope slide of a butterfly as a gift and was inspired to make a little video about it #sciart #microscopy 📽️ youtube.com/shorts/vVKCkiw… Apparently back then, people had microscopes at home as a form of entertainment! #scienceisforeveryone

I got a used Nikon Labophot #microscope to do some fun #scienceathome! Check out this video of bird bath water I was able to take through the microscope with my phone. Still learning to identify protozoan microorganisms though! #scienceisforeveryone 📽️ youtube.com/shorts/0X0ntb5…

Just got my Presidential Early Career Award #PECASE certificate in the mail! 🎉 Grateful for #NSF grants that power our #BiomedicalResearch. Reminder that federally funded research creates valuable public goods that help us reach our full potential. #ScienceMatters #FundResearch

Interested in learning more about #AI in molecular #biology? Students can apply for a scholarship and short talk at our @KeystoneSymp this September: keysym.us/KSAIBio26 #KSAIBio26 Deadline June 3, 2025 Check out our speakers lineup with academic and industry leaders! 🥳🥂

To supplement my students' learning, in this #bioinformatics #dataanalysis #codetutorial, I walk through how to analyze #spatialtranscriptomics data to identify spatially variable genes using the Moran’s I statistic #Rstats Code along: youtube.com/watch?v=aaANPo… #AcademicTwitter

Another semester done 🥳 I reflect on how I chose to accommodate a student who wanted to miss class to attend a political rally, and how I promote the ideologies of freedom of speech and democracy through my teaching of computer science: jean.fan/2025/05/05/i-t… #AcademicTwitter
