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!

Ours flower much later into winter!

In the eastern deciduous forest, keep your eyes open in the next few weeks for the dramatic flowering of witch-hazel, Hamamelis virginiana. It is the only native tree that flowers in late fall or early winter. Read about it at Our Trees, and go look for it in your woods in a couple of weeks.

One of our most charming small trees is witch-hazel, Hamamelis virginiana. It is founnd in rich forest understories, especially near bottoms. You may know witch-hazel for the medicinal use of a distil...

This is profoundly sad. We lost a true pioneer in the field of psychiatry

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.

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)

This is a section of postmortem tissue from an adult human brain donor. The area we are studying (locus coeruleus) is in the brainstem, and those neurons that accumulate the pigment (neuromelanin) are the first to accumulate Alzheimer's disease pathology and are highly susceptible to degeneration

🚨 🚨 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...

🐟 Talk about jaw-dropping evolution! 😮 Bahamian pupfishes show huge craniofacial diversity with tiny genetic tweaks. 🎏 Here’s C. desquamator, where 🟠 atp8a1 Is expressed just the jaw muscles (🩷tpm3b)🔬image from @fishfena.bsky.social

For #FluorescenceFriday, α-spectrin (red) and lipid droplets (green) are shown in adipocytes 🔬 #Microscopy #CellBiology

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.

Watch to the end! Immune cells in the retina remain flat until damage is detected. Cells change their shape and dive deep in response to damage (pink cell)
