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."

Here is the transcript of the meat of Carney’s proposal for a deeper Canada and EU partnership in text. Full text of the speech at the second link. The 2 minute video clip got a chuckle (“better manners”).
“So let me say plainly what Canada proposes.
Canada and Europe should secure our strategic autonomy through deep cooperation in the full range of strategic capabilities, including critical minerals, defence industrial capacity, AI and compute, energy security, space, and payments.
We should move toward seamless, digital trade in non-agricultural goods and a wide range of services.
We should deepen our people-to-people ties, allowing our youth to live, work and study where they want on either side of the Atlantic.
Canadian membership of Erasmus can give your students, and ours, more opportunity to learn at some of the world’s top universities, to broaden their horizons, and to build lasting ties that will sustain our alliance for the future.
Canadian membership of the next generation of Horizon would allow us to pool resources, cooperate on frontier technologies, and leverage our world-class research institutes and universities.
Yesterday, President von der Leyen announced a “new European Corporation on Critical Raw Materials” to obtain and stockpile the material needed for electric cars, chips and batteries, clean technology, and defence. Canada has deposits of over 34 critical minerals, and we are among the top producers of the 10 most essential for the world’s energy transition. Our alliance can help fill Europe’s need for reliable supply, Canada’s need for advanced processing capabilities, and our common objective to build complete value chains.
Canada can contribute LNG and hydrogen at large scale to support Europe’s energy security including by developing and leveraging new port infrastructure in the High North and on our East Coast. We, in turn, can benefit from your leadership in many clean energy technologies.
We can pool new sovereign compute capacity and build more secure broadband connections between Europe and Asia via our common geography.
Canada and Europe can join forces to develop AI safety protocols, coordinate common standards, and strengthen transparency, all while developing applications so our governments and companies can serve our citizens better.
Canada and Europe should also consider exploring an integrated market for financial services to broaden choice and reduce costs for our citizens, improve access to capital for our companies while maintaining our world-leading financial resilience.”
