Hi, #ScienceMastodon! It's time for an #introduction. 👋

I'm a PhD candidate in the Tolić lab where I study cell division & aneuploidy using STED, LLS & confocal #microscopy. 🧬🔬

Here's a video of the cell with marked chromosomes and tubulin going through mitosis. Chromosomes are colored for depth.

Arrived at Buxted Park for "Genotype to Phenotype: Bridging Comparative Genomics and Cell Biology" workshop
organised by Gautam Dey & Eelco Tromer
run by the Company of Biologists

Bringing #TinyFish content to Mastodon. I'm a marine scientist who studies the biodiversity and functioning of reefs. My lab at UT Austin works mostly on tiny, bottom-dwelling fishes – these little guys are gorgeous but few of them grow larger than a couple of inches... 🤏 🐠 #Ecology #Biodiversity #TeamFish #Fish

Let's start with the #FluorescenceFriday @ mstdn.science !!

Here you have "the explosion of life" during #cell division.

“Maybe you know me from Twitter?”

This looks interesting. https://www.biorxiv.org/content/10.1101/2022.10.21.513099v1

First toot! Who's here? You may know me from the bird app as the one who is obsessed with #cilia and #protists. Here is a YouTube vid (several years old) of some psychedelic #Chlamydomonas #cilia to prove it.

I mentioned this in a private message to someone recently about why a small handful of servers block qoto. I wanted to reiterate it here for the new comers on QOTO who dont know the history:

So there are some servers out there that demand every server int he network block every instance they do, and if a server doesnt block an instance they block then they block you in rettatliation.

Their reason for this is quite flawed but it goes like this.. If we federate with a bad actor instance and we boost one of their posts then their users will see it and defeat the purpose of the block. The problem is, this isnt how it actually works. If they block a server and we boost it, they wont see the boost, thats how blocks work.

The issue becomes even more complicated when you consider the fact that these servers, by virtue of their policy, have huge block lists where they block tons of major servers. So in order to satisfy them we too would have to block a huge number of servers.

This means you have a choice, you either join a server that isnt blocked, but has a huge block list themselves, or, you join a server that doesnt block and be blocked by a small handful of servers. Obviously that means on QOTO you will have bigger view of the world than you would on any of these others servers. In fact QOTO has onne of the largest federation footprints of any server in the network.

I want to also explain why we choose the decision we did. Years ago when this controversy started and servers across the fediverse started blocking there was a divide of people taking sides. WOTO was one of the few servers that didnt take sides and allowed people read content from any server (but with strict hate speech rules). This caused a huge influx of people,s pecifically from the LGBTQ community, onto our server. It turns out many people relied on us not-blocking for their physical safety. There were big name biggots (like milo yanappolus) who were on the network. They used their accounts here to watch his account for doxing so they could warn themselves and their community and protect themselves accordingly. In fact we added a feature just for them called subscriptions which allowed them to monitor accounts without following them so they could do so anonymously.

In tthe end for the safety of the LGBTQ community here we refused to engage in mass server blocking and instead encouraged our users to block servers on an individual basis and provided access to block lists for them to do so. But some really misguided servers blocked us anyway.

Thankfully the servers blocking us are few and far between and are limited to only the most excessive and aggressive block lists. As I said, QOTO has one of the largest federation footprints on the fediverse,

The machinery that make #mitochondria the POWERHOUSE OF THE CELL™️ is found on the inner mito membrane. These membranes are folded up into structures called #cristae that increase the surface area of the membrane (to make more ATP).

Where did cristae come from? How common are they in #bacteria?

Here is a beautiful new paper from Victoria Orphan et al. showing that alphas are not the only bacteria that can make cristae. Check out these cristae in #Desulfovibrio (!)

Because I'm on a German server my trending topics are #keinVergessen and #niemalsVergessen. This is because 9 November is the anniversary of Kristallnacht.

These brass plates in the pavements memorialise Jewish people at what were their addresses. I saw this one in Berlin in the spring. #NeverForget

If you have a toot problem you should see a mastodontist.

I feel like Mastodon doesn't have enough cells doing weird things. #cellbiology

These are neutrophil-like WAVE-null HL60s doing "serpentine blebbing" when confined under an agar pillar.

Wild that cells with such a messed #cytoskeleton can still move so well. They're moving ~10um/minute here.

People who think a meeting could have been an email haven't seen my inbox

I’m missing a couple hashtags from my #introduction post, which is a big deal without an algorithm!

I’m interested in #cellmigration #cellvolume #membranepotential #ionchannels #cytoskeleton #cellfatedecisions. And too many others things 😅

#introduction

Cell biologist, student of the #cytoskeleton, professor and dean at The Rockefeller University in #NYC.

Interested in #centrosomes, #cilia, and science #education, #outreach and #policy.

My #introduction to #ScienceMastodon:
I am a #Cell #Biologist and research group leader at IRB Barcelona, Spain.
In my lab we observe the #microtubule #cytoskeleton and try to make sense of what we see, what an awesome job!
We also like hashtags that start with C:
#cell #cytoskeleton #centrosome #centrioles #cilia

@AnhHLe2702 Ironically, it appears we’re slow at migrating!

Where are my #cytoskeleton, #cellmigration, #actin folks on Mastodon? 😭 So far I only see the bioinformatics and neuroscience folks on here.
