#29 Genetic evolution and mutation.
What you see in four steps is the cell division created with a metaball algorithm. You should know that my two favorites in generative art are metaballs and noise. And they are both similar because the results look like organic fluid or very soft materials.
Also, I thought to try these 4 quadrants instead of an animation because often you do not have time to watch a whole animation. But both have their existence.

Meet Gabrielle Schick, a master's student in the Department of Biology conducting research in Dr. Alisa Piekny’s lab. The lab studies how cells divide using tools like CRISPR and molecular cloning. Her research focuses on understanding how specific proteins are regulated during cell division, a process that is essential for growth, development, and tissue maintenance.

About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it activates other proteins involved in this process. Plk1 is also overexpressed in many types of cancer. This makes it a promising target for cancer therapies. However, drugs that inhibit Plk1 have often proven ineffective.

Holding Steady
Before a mammalian cell divides, the spindle — a protein structure — divides the cell’s genetic material in two. As it does, the cytoplasm inside the cell forms a toroidal flow (below, left). Researchers wondered how the spindle manages to stay in place with this flow; the spindle sits just where the flow diverges, a spot that seems ripe for unstable shifts in position. But, contrary to expectations, their analysis showed that — although a smaller spindle would be unstable in that spot — the protein spindle is large enough that its size distorts the cell’s flow and creates a pressure that moves it back into place if it shifts.

Scientists have captured the most detailed images of cell division ever using a new microscopy technique. The technique, called lattice light-sheet microscopy, allows them to observe the movements and interactions of molecules inside living cells in 3D and real-time. It could reveal new insights into the mechanisms and regulation of cell division and the causes and consequences of errors that lead to diseases such as cancer.
