Can you spot the difference between the cells on the left and right?

Read on for the solution (and a preprint announcement)… 👇

🥳 Happy #DNADay!

🧬 What better way to celebrate than with cycleHCR: one of our newest tools, developed by the Liu Lab, that uses a novel DNA barcode system to track hundreds of RNA & protein molecules in single cells within thick biological samples ➡️ www.janelia.org/news/new-met...

Igor Siwanowicz of @hhmijanelia.bsky.social captured these photos of pollen grains on the sigma of a morning glory flower. This is part of the early stage in creating a seed, it might also be the reason why you can’t stop sneezing!

I was wrong before, *this* was actually tailor-made for me.

Our next curious guest is Jacob Collier! The episode comes out on March 26th at youtube.com/complexly!

If you know Jacob, you already know you're in for an exploration of creative and philosophical ideas with infectious enthusiasm.

Yes, the paper is cool...
BUT if you’re a fan of fly vision and neuroanatomy, the Supplemental Materials are the real treat 🎉
We made a catalog of all the cells and it's ✨beautiful✨

It can feel like we have made no progress in the fight against climate change.

That's not the case.

We read "Large Concept Models" in our reading group. It models language at the sentence resolution - "concepts". We had lots of thoughts about it! You can read them in our new Janelia CVML blog post:

Immagine you could image two cellular structures in the same fluorescent channel and still reliably get them separated afterwards…
What would you do with this?

Now… what would you do if that also worked with 4 structures at once? 👇 #MicroSplit #preview🧵
Schematic overview on how MicroSpit operates. It can split superimposed structures in fluorescent image channels by using a suitably trained AI. Concrete example for how MicroSplit unmixes four superimposed structures.

What's in a QuAC? | Funke Lab

Using QuAC, we can translate a GABA synapse into an ACh synapse by making minimal changes (highlighted). The images are much easier to compare: now we see that the post-synaptic density got darker.

Now that we know what to look for, we can actually see this feature in the examples above!

5/6
A query synapse, of class GABA, is on the left with its classification. It is converted to a counterfactual synapse of class Acetylcholine. The changes are minimal and highlighted with a contour.
adjavon.bsky.social
We developed QuAC specifically for biomedical applications.

Here is our favorite example: it is really difficult to notice any obvious differences between EM images of synapses releasing different neurotransmitters (e.g., GABA vs. ACh). There is just too much going on!

4/6
Two sets of images of synapses in EM. The synapses on the left are GABA, those on the right are Acetylcholine. They are grouped in a 2x2 matrix each
