This is the most detailed picture of a human cell ever made 🧪

Sam Bousaba on Instagram: "This is a single human cell. The white filament-like structures are microtubules, and the small colored particles are ribosomes. Your body contains on the order of ~37 trillion cells. Each cell functions like a highly organized, self-regulating factory operating continuously. There is no central “supervisor”—yet thousands of processes run in parallel with remarkable coordination. Every ribosome is constantly building proteins by linking amino acids together. In eukaryotic (human) cells, a ribosome typically adds about 5–10 amino acids per second (not ~20). Since a single cell can contain millions of ribosomes, protein production is massive—resulting in millions to tens of millions of peptide bonds formed per second per cell. The microtubules act as an internal transport network. Motor proteins such as kinesin move along these tracks, carrying cellular cargo. They “walk” step by step using ATP, at speeds of roughly 500–1000 nanometers per second. Each cell contains a dense network of these filaments, with many motor proteins moving simultaneously. Just beneath the cell membrane lies the actin cortex, a dynamic meshwork that helps maintain cell shape and resist mechanical stress. This structure is continuously remodeled—assembled and disassembled—allowing the cell to adapt to its environment. Now scale this up. Across ~37 trillion cells, each containing millions of ribosomes and hundreds to thousands of mitochondria, your body is constantly producing energy in the form of ATP. Total ATP turnover is enormous—roughly equivalent to your body weight in ATP recycled every day. The DNA in a single human cell, if stretched out, measures about 2 meters. Across all your cells, this would span distances comparable to traveling from Earth to the Sun and back many times (the exact multiple depends on assumptions about cell count and DNA packing). None of these processes are under conscious control. They began when you were a single cell and have continued uninterrupted ever since."

Netflix: Generative KI steckt in rund 300 Filmen und Serien
Generative KI kam bei rund 300 Netflix-Titeln zum Einsatz, vor allem in der Postproduktion. Großartige Künstler brauche es trotzdem, sagt Ted Sarandos.

In the beginning was Chaos.
So...what's new? Longer legs?
Magnum Chaos design, as shown in a 16th-century design in the church of Santa Maria Maggiore in Bergamo, Italy
#Religion #Chaos #Philosophy

Magnum Chaos design from a late Medieval church decoration. The design shows a violently flaming golden sun, with concentric circles within--behind an imaginary creature with an eye in its center, forearms and hands spread wide, and ankles and feet. The creature appears to emanate from the sun and concentric circles.

After 17 years of construction (the plan was 4.5 years), 2 years of commissioning, and a few months of operation, France's new #nuclear power plant Flamanville 3 is now getting ready for the replacement of its reactor head. It will be out of operation for a year.
