Hold on a minute...

He called it a toot in his toot. Referring to his own toot, he said post or toot.

That's what he said in his toot. Or post, as I won't call it.

"Post-embryonic remodeling of the C. elegans motor circuit" by Ben Mulcahy et al. 2022 (Mei Zhen's lab https://zhenlab.com/)

... in which the authors show, using #vEM and #connectomics, that while the nematode #celegans nervous system grows from ~200 neurons in the hatchling to ~300 in the adult, the addition of new neurons doesn't disrupt existing motor function, but new circuits are formed that endow the animal with new behaviors such as bending.

Interestingly, in the course of larval maturation one neuron type inverts its polarity: what was the dendrite becomes the axon, and viceversa. And this is accomplished not with retraction and regrowth of the arbor, but rather, by flipping the synapses in situ.

In my course MCB111 "mathematics in biology", we just learned about Hopfield networks and the Hebbian learning. Can anyone give a critical reading of this paper for us?

@freemo @Waldemar I'm talking about following hashtags, here:

I really like the feature on my instance (#qoto) where I can make a list that shows posts with any of a set of hashtags. I've got one list that shows me all posts tagged #drawing or #sketching, and another that shows me anything tagged #oregon, #portland, #pdx, #orpol, or #pdxpol.

Hello. This is my first post. Or Toot as I won't be calling IT. My interests are...

Hello, all. I’ve been around for a few days but haven’t yet made an #introduction post. So here we go.

I’m a #bioinformatics consultant with The Bioinformatics CRO working on a variety of small and large projects ranging from fundamental genomics to clinical decision support. Before that, for several years I was a postdoc and ORISE fellow specializing in high-altitude medicine and physiology at the University of Colorado Altitude Research Center. My academic background is a nearly even mix of #biostatistics, machine learning, and biology.

The ARC* has been sadly moribund for a few years, but thanks to collaborations with other groups, we’re starting to get more active again. Hopefully I will have more to say about that in the future. Meanwhile, feel free to ask me anything about #altitude medicine—I think I still remember most of it.

Years before that, I was an Air Force #medic (after a brief stint as an Army infantryman) followed by a couple of years as a civilian EMT. My time in patient care informs my approach to science: the numbers I crunch represent human lives.

Otherwise, I’m an armchair #paleontologist hoping to be able to call myself an amateur paleontologist again one of these days—by which I mean actually spending some time in the field and/or the prep lab—a too-occasional science fiction writer, and chronically sleep deprived. Also, my life is the internet: it’s cats all the way down.

*Fellow #Primeval fans may recognize the jacket in the picture. My wonderful fiancée found it for me when I was hired at the ARC, for exactly the reason you think.

I've been thinking about how we can use what we learned about remote work & virtual meetings from the pandemic. It would be great if we didn't have to release lots of carbon to meet, and could live wherever we wanted. But, there are downsides to virtual everything, particularly with our current tech & practices.

Should we really be trying to go back to how things were? Can we learn from our pandemic experience? What are the best practices & tech for setting up virtual and hybrid meetings? Do we really need VR and avatars for virtual/hybrid to work? Are there advantages, for certain kinds of people, of virtual platforms?

This is likely a personal preference: I think virtual works as well as in-person when communication is mostly one-directional, e.g. prepared talks and, to some extent, poster sessions. If conferences are mainly talks and posters, I think they should be virtual.

I am hoping that n-way virtual communication could be better with better organization and technology. Places like CERN have been doing hybrid & virtual meetings for a long time. Can we learn from them? https://qz.com/1832018/how-physicists-solved-your-zoom-video-conferencing-problems

Now to be a bit cynical -- I think those in charge are those that did/do well in our old/current system, but that system is not great for everyone. Again, this is personal, but I'm better at expressing myself in writing. I'm more likely to ask a question at a conference if I can enter a virtual queue. God I dread mixing at conferences. This one time there was "science speed dating" at a conference. It was torture. Maybe for some people sometimes virtual can be better?

Anyways, I thought I'd use this virtual platform to bring up these ideas! I know many disagree on this and are happy to get back to conferences. I'd also like to mention that for people who continue to be concerned about COVID, going back to normal is not yet possible (will it ever be??). For me, this article rings true: "For those still trying to duck covid, the isolation is worse than ever" https://www.washingtonpost.com/lifestyle/2022/10/26/covid-pandemic-still-isolating/
