Our new study shows that SARS-CoV-2 spike protein accumulates & persists in the body for years after infection, especially in the skull-meninges-brain axis, potentially driving long COVID. mRNA vaccines help but cannot stop it🔬🧠🦠🧵Your weekend read👇

I am super excited to share our latest work on the native in-cell organization of the mitochondrial respiratory chain 🥳
Using cryo-electron tomography 🔬, we show how the respiratory complexes (and other complexes) are organized inside native mitochondria!

I'm loving the starter packs! But didn't see one for all CNS injury researchers (stroke, TBI, SCI, etc). Can you help me build it?

The Orion Nebula (M42) is a stellar nursery 1,344 light-years away. It glows in vibrant pinks, reds, and purples, where young stars form from swirling gas and dust. This iconic nebula offers a glimpse into the process of star birth in the universe.

The Orion Nebula (M42) radiates in vivid reds, whites and pinks, with glowing clouds of gas and dust surrounding young, bright stars. Its intricate structures reveal the chaos and beauty of star formation.

The Orion Nebula is a diffuse nebula in Orion's Belt in the constellation of Orion. It is 1,344 ± 20 light-years away.

Shot from my backyard a few years ago. I will revisit this object soon.

Good morning #Bluesky community!
How about a little Timelapse of the recent aurora storm to start the day.
This night will forever be a happy moment for me, a night of sheer beauty.
I think I mostly said “WOW”! 😆

A cool discussion w/ some colleagues from the #NeuroSky community has triggered a new #ComplexityThoughts 👀

Regardless if you work w/ 🧠 or 🧬🧫, often we attack inverse problems in 🧪 w/ methods hiding tons of assumptions. I write about the case of #ComplexNetworks 👇
