This is the most detailed picture of a human cell ever made đź§Ş

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."

Die Regierung redet so gerne von Effizienz in der Verwaltung: knappe Mittel mit möglichst hohem gesellschaftlichen Gewinn einsetzen.
Tipp: Finanzämter prüfen¹ vordringlich die Steuer­erklärungen der Überreichen und großen Unternehmen², von einem Teil der Mehreinnahmen bilden wir mehr Finanzbeamte aus, solang sich das positiv rechnet.
Parallel dazu könnten Medien diejenigen Steuer­vermeidungs­modelle anprangern, die die Regierung sich weigert zu schließen. Mit Gegen­rechnung, wie…

Perpetual motion machines are the primary example high school physics teachers use for something you can know is an obvious hoax no matter what the details are.

I am a Power User, of which this essay speaks.
I will give up only when they take the tools from my cold dead hands.
I _continue_ to remain considerably angrier about it than most people currently are.

According to Justice Department’s own account, 15 arrested by federal government in Minneapolis this week are responsible for denting gov F-150 (by kicking), & tipping tailer (owned by accused). That’s it.
Why hasn’t potus nuked Minneapolis from space? /s
Attack on Americans & 1st Amendment makes me think we’re not free country I thought we were & realize perhaps never were, I was “lucky” not to notice before.
