The Penrose-Hameroff Orch OR model places the essential aspect of consciousness at the level of quantum computation in microtubules within the brain's neurons. "Tubulin" proteins comprising ...

Microtubules are major components of the cytoskeleton. They are found in all eukaryotic cells, and they are involved in mitosis, cell motility, intracellular transport, and maintenance of cell shape.

Microtubules are the largest type of filament, with a diameter of about 25 nanometers (nm), and they are composed of a protein called tubulin. Actin filaments are the smallest type, with a ...

In 2015, researchers examining deep-sea sediments near the underwater volcano Loki discovered gene fragments indicating a new ...
