For all the new followers (thank you!!), I love to post images about our science - team #FluorescenceFriday - as well as DC city stuff, #nativeplants, sunsets, sunrises, paddling and all things Chesapeake!

🚨 🚨 Science alert on a #FluorescenceFriday; check my latest paper published in @genetics-gsa.bsky.social where I integrated comparative tissue-specific transcriptomics and speciation genomics to discover two novel craniofacial genes behind pupfish extreme jaw development! tinyurl.com/craniofacial...

Viral trigger in Alzheimer’s disease is the real scary spooky #FluorescenceFriday.
Amyloid-β🟣 is an antimicrobial peptide that can be produced to trap pathogens in the brain. But it also induces an extensive neuroinflammatory response, as shown here with 🟠astrocytes. #NeuroCovid

15 years in the making, we confirmed that mitochondria - the powerhouse of the cell - have an unusual localization in patients who experience psychosis (including schizophrenia and bipolar disorders). You’ll never guess what kind of patient cells we used to make this discovery… 🧵

mitochondria from bipolar patients are closer to the nucleus in these images; control patients' are spread out further

MIT became the first university to reject the Trump administration’s compact of demands, after its president Sally Kornbluth said the school already “meet or exceed many standards outlined” by the federal government.

Super excited about this ongoing spatial transcriptomics study in locus coeruleus of human 🧠. Expression of norepinephrine neurons - TH🔴, DBH🟢 and SLC6A2🟡 overlaid on post-Xenium H&E stain, allowing correlation of neuromelanin content (brown pigment) w/ gene expression #FluorescenceFriday 🔬🧪

mRNA expression using in situ sequencing (Xenium) on a tissue section at level of human locus coeruleus shows expression of marker genes for norepinephrine-producing neurons (TH in red, DBH in green, and SLC6A2 in yellow. Expression of markers is overlaid on the H&E histology staining, which shows cell bodies (purple) and neuromelanin (brown)

Happy #FluorescenceFriday! This is a maximum intensity projection of depth shaded actin (🌈) in a section from an E9.5 🐭 neural tube (NT). 🔬 by postdoc @christinaadaly.bsky.social 👩‍🔬 🧪 Image shows the floor plate and lumen of the developing NT.

My first time sitting down with a real sample. Phase separated membrane in a yeast lysosomal vacuole. Green is the V-ATPase, in the liquid disordered domain, and magenta is Ivy1, a protein that associates with the liquid ordered domain. This vacuole is about 2 microns in diameter.

Also, re: the glossiness of those berries - yes, it is really striking. I have a Winterberry (Ilex verticillata) right near that plant also with amazing fruit set this year, but with them close together struck me how glossy the Chokeberry was.
