Wanna see DNA transcription, translation, ParM filaments assembling and travel through the basement membrane of follicle cells?
Check out the reel I prepared with animations for academia.

Thank you!
I'm not sure the structure holds exactly like this as long tubes. They can stack multiple turns as I saw in some publication. But not sure how it looks in the actual organism.

I created this image for the PDB molecule of the month visualization challenge and February's topic is "Histones Across the Tree of Life" and you can find other examples at: pdb101.rcsb.org/motm/314
If the PCR method was a revolution what could give us the ability to stabilize DNA at high temperatures as archaea do?
However, none of this happens to archaea Methanothermus fervidus which thrives at 83ยฐC in sulfur pools in Iceland. This organism compacts its DNA with the aid of heat resistant histones (shown in green in the image), and other proteins such as Alba, Cren7 and Sul7d (omitted in the image).
It is a disaster our bodies avoid by giving us the painful burning sensation.
At 83ยฐC, the eukaryotic nucleus falls apart as scaffolding proteins collapse. Histones and other binding proteins detach from the DNA resulting in loose DNA. These unwrapped DNA strands then melt at multiple points separating into single strands that no longer keep together.
The image shows DNA nucleosomes arranged from histones in archaea. DNA is portrayed as an incandescent metal in a heated environment.
February's PDB Molecule of the Month is for "Histones Across the Tree of Life".
I wanted to focus on the histones of archaea Methanothermus fervidus which thrives at 83ยฐC in sulfur pools in Iceland.
I call the image: "Compacting DNA at nearly boiling water."
Who knew that Blender could help us study the stars? ๐ In this new User Story, Ph.D student @jamshidi3d.bsky.social explains how he used Geometry Nodes for his research in cosmology.

Cutaway and close-up views of a Martini coarse-grained whole-cell model of JCVI-syn3A, showing the densely packed cytoplasm with proteins, RNA, metabolites, and chromosome inside a lipid membrane with embedded membrane proteins
Our paper on [Bentopy](doi.org/10.1002/pro....) is out in Protein Science! We developed Bentopy to make assembling large-scale MD models more accessible, building on what we learned from trying to simulate whole-cell models. Here's our updated Martini JCVI-syn3A cell model๐

As we get ready to watch Ilia Malinin skate, please read this fascinating piece by my colleague @parshallison.bsky.social about how the self-appointed Quad God is able to do what he does. And how figure skaters have been able to land progressively more difficult jumps. โธ๏ธ ๐งช
Amazing ๐คฉ!
So interesting that the GTP cap is not spatially regulated!
Thanks to everyone who participated and I have a blog post here with lots of resources that can help with scientific figure design, posters, grant figures, and data visualization!

Read the case study from my last image were we reimagined nanotechnology artistic illustrations ^_^

Thank you so much Tenjimbayashi-san and the team of MANA for trusting me for this artistic, yet scientific image ^_^.
The researchers wanted a new look to nanotechnology.
In their experiments, the "Micro liquid droplets" succeed in many "challenges" that neither solid marbles nor water could.
We wanted to represent the different properties and also their tiny size, while giving it a sweet gentle artistic touch.
What if we could have nanodroplets to deliver drugs or perform chemical reactions, but that they don't stick to surfaces, yet they can merge on demand?
Tenjimbayashi-san and coworkers from the Research Center for Materials Nanoarchitectonics in Japan made it! ๐

Super cool! I guess the organism's size and temperature matter, is that so?

The image shows nanocages made of RNA in white with abstract colorful crystals inside.
RNA-only Nanocages - a white canvas for biotechnology?
What could they store inside?
Could they be used for drug delivery?
I made this image for The Molecule of the Month Challenge from Blender Science Discord.

New paper out!
We show how mechanosensitive adherens junction proteins link actomyosin contractility to actin assembly using in vitro reconstitution.
Huge congrats to Aurรฉlie Favarin, Rayan Said, & all authors!
In Science Advances: www.science.org/doi/10.1126/...
#actin #myosin #mechanobiology
What an elegant assay and great discovery! I would love to see the effect of other proteins that promote contractility in the future.

Simply delighted to end the year with the acceptance of Yanโs paper www.nature.com/articles/s41.... It was a heroic effort on her part, and many thanks to all our collaborators for their help!
