Hi #ScienceMastodon #Introduction here! I study cell fate determination and growth regulation in #Drosophila for my #PhD. Currently wrapping up at UMass Boston, and moving on to the #postdoc position soon at UMass Chan Medical School to explore new areas in epigenetics. Delighted to be here!
It's probably time for an #introduction after lurking for a while.
I am a recent addition to the Nature Structural & Molecular Biology editorial team. I have very recently handed in my PhD - I used #cryoem and #cryoet to study #structuralbiology of viruses and vesicular trafficking.
Looking forward to engage with the #science community here!
"growth is a non-monotonic function of volume in yeast cells, with maximal values around the critical size. Comparing small to normal, large and outsized cells, the transcriptome undergoes an extensive inversion that correlates with RNA polymerase II occupancy. Accordingly, highly expressed genes impose strong negative effects on growth when their DNA/mass ratio is altered. A similar transcriptomic inversion is displayed by mouse liver cells of different sizes [...] cell size is set to attain a properly balanced transcriptome and, hence, maximize growth during cell proliferation."

Very cool study from the Garcia-Manyes Lab (TheCrick) exploring the previously dark side of the energy landscape of talin’s R3 domain using magnetic tweezers! Tapia-Rojo et al. observe new rare conformational states, beyond being binary, some of them capable of binding vinculin. These states may encode a new layer of mechanosensitivity in talin's R3 domain! #mechanobiology #biophysics

#introduction I'm a computer scientist, former professor now software engineer @ CZI. My interests are around image processing, software, and physical sciences. I am very into artificial life;" the study of life as it could have been."I was at formerly affiliated with Hampshire College, Brandeis University, Harvard Medical, HHMI Janelia Research Campus, UIdaho, DARPA, Max Delbrück Center, and Oak Ridge National Lab.

I've had some fun with tyssue (https://github.com/DamCB/tyssue). It is a 3D epithelium simulator, and I'm curious if folks other than @glyg on here are using it.
Hello #ScienceMastodon ! I just made the Twitodon transition so a bit of #introduction: I'm a PhD Student interested in #DevelopmentalBiology, #Embryology and sometimes #StemCells and #Transcription. Looking forward to less promoted posts and more #AcademicToots.
Don't forget that Janelia's Computation & Theory area is looking for both [Senior] Group Leader candidates (https://www.janelia.org/our-research/our-labs/group-leaders) and Theory Fellows (https://www.janelia.org/our-research/overview/theory-fellows)! Are you working on interesting computational and theoretical approaches to address fundamental biological questions? Talk to us!

I thought I would share this image, which I took a while ago, but that I really like! This is a #pituitary gland where cells expressing a protein called proopiomelanocortin (POMC for short) have been coloured in green. You can see two groups of cells; a very packed band in the middle and some sparse cells on the sides. The first are called melanotrophs, and they are important in determining skin and fur colour. The sparse cells on the sides are called corticotrophs (and that's what I am studying at the moment!) and they are important for the response to #stress . They secrete an #hormone called ACTH which stimulates the production of the stress hormone cortisol from the adrenal gland. At the moment we are trying to understand what happens to this cells after the body is exposed to stress for a prolonged amount of time. #scicomm #biology #science #physiology #microscopy
📢 📢 Exciting chance to come join us on a #rotation-based, 4 year, international #PhDStudentship- include our #TubulinCode project! Closing date: 9th January 2023. #imaging #cytoskeleton #cilia #ciliopathies #GenomeSurgery #RareDisease Message me, if you want to hear more! 📢 📢
We know that #centrosomes are not required for mitotic division, so what are they good for?
New preprint from the lab shows that having two duplicated centrosomes at the beginning of #mitosis facilitates rapid bipolar spindle formation. In the absence of centrosomes there is a checkpoint-mediated delay that is required to give enough time to sort things out and assemble the spindle.

Moving toward a better #resolution: our structured illumination microscope (SIM) allows to get 2 times better detail than classical widefield or #confocal #microscopy. Here's a #cellfie of a monkey cell labeled for the endoplasmic reticulum (yellow), clathrin (blue) and #actin (gray) 🔬
For a few months now I've considered doing a series of posts on women in #RNA #research (mostly PIs, maybe some #postdocs). My idea is to take the latest paper of their group and present it while highlighting previous key work. I already have a list of ~50 researchers (biased for those I know) - enough for a year of a weekly series.
Originally, I thought of doing it on the birdsite, but I just couldn't find time for it.
Moving here might be the kick I need to begin - hopefully this weekend.
As a #colourblind person, I appreciate people checking their figures in greyscale. But it's a lot of work to always convert your figures into greyscale, right? A lesson from digital artists: you don't have to!
There are easier ways for all operating systems! (see replies)
----
Checking your figures in greyscale may not resolve all visual impairment issues, but it really helps! Plus, it allows YOU to appreciate *contrast*. Use contrast to your advantage!
I'm a professional dog sitter doing a postdog at Stanford co-advised by two Samoyeds 😅 I do single-molecule force spectroscopy as a side hustle! I’m enthusiastic about proteins especially kinases in AFM, magnetic tweezer and optical tweezer assays! Follow me for #biophysics #singlemolecule #mechanobio content 🤗
Did you know that you can copy-paste images into the text field, and they get added to your toot as if you had appended them? Very handy to avoid creating intermediate files, by right-click on a PDF, copy image, and paste here; or right-click on an image on a website, and paste here.
Did you know that you can follow hashtags? A convenient way to follow entire domains of knowledge without having to find its members first.
Did you know that the website works perfectly from a mobile web browser? No need for an app; the latter are often better looking, but lack some of the functionality.
Did you know that starring a toot doesn't promote it? It's only like an "I see you" and a bookmark of sorts. (The is also a bookmark button, which is just that, without telling the sender.) If you want to promote a message, boost it.

Biologist currently working at the Curie Institute.
I just finished my PhD on liver development and cell polarity in mice and recently started a post-doc on fly morphogenesis.
I'm mainly interested in microscopy, image analysis, biophysics and developmental biology.
