Human Perfect Cell and Red Ribbon Army lore but it’s covered with thirst traps because I just learned a new way on how to draw muscled bodies. I just love the manhwa art style wahhhh!

Yes im still alive. I’m trying to draw as much as I can in all the midst of irl work busyness because I just simply love to draw! This year is pretty slow but it’s still better than nothing! :D

Edit: a funi I made on Insta story

Microscopic Droplets Reveal DNA’s Secret Architecture

New ultra-detailed imaging exposes the hidden structure and behavior of chromatin condensates — and hints at how their failures may drive di

"Six feet of human DNA crammed into a tiny nucleus relies on an elegant system of nucleosomes, fibers, and highly organized phase-separated condensates.

Scientists have now captured the most detailed images yet of how chromatin fibers and nucleosomes arrange themselves inside these droplet-like structures, revealing how molecular architecture determines condensate behavior."

"Inside every human cell, biology manages an extraordinary challenge: packing roughly six feet of DNA into a nucleus that is only about one-tenth the width of a human hair, all while keeping the genetic material fully functional.

To achieve this level of compression, DNA coils around proteins to form nucleosomes. These nucleosomes connect like beads on a string, creating long strands that fold into chromatin fibers. The fibers then compact even further to fit inside the nucleus.

For years, scientists did not know exactly how this final stage of compaction occurred. That changed in 2019, when HHMI Investigator Michael Rosen and his colleagues at UT Southwestern Medical Center showed that lab-made nucleosomes can gather into membrane-less droplets called condensates. They discovered that this occurs through phase separation – a process similar to oil droplets forming in water – which may mirror how chromatin becomes densely packed within living cells."

"Looking inside chromatin condensates"

"These chromatin condensates, made up of hundreds of thousands of rapidly moving molecules, have emergent properties—behaviors that aren't present in the individual molecules but appear only when they work together as one. These properties dictate how the droplets form and maintain their physical characteristics.

To better understand these qualities, which could help researchers learn how chromatin compacts inside cells, scientists need to peer deep inside the droplets to examine individual chromatin fibers and nucleosomes.

Now, Rosen and his team, along with researchers led by HHMI Investigator Elizabeth Villa at the University of California, San Diego; Rosana Collepardo-Guevara at the University of Cambridge; and Zhiheng Yu at HHMI's Janelia Research Campus; have figured out how to do just that." (video)

Understanding the Human Cell its 4 parts, how important

The Human Cells are the basic building blocks of living things and they provide structure for the body, take in nutrients from food, and convert those nutrients into energy, Cells can make copies of themselves and they contain the body’s hereditary material, Cells group together to form tissues; tissues group together to form organs like the kidney and brain; organs group together to form systems…

If there was a live action DBZ iteration, Jon Hamm would be the perfect Perfect Cell

His facial structure aligns with Cell's so freaking well. He can pull off that snarky smirk and smug charisma.

If Cell were human, he'd look like Jon Hamm.

You can't tell me I'm wrong.
