Secret Universe

The Hidden Life Of the Cell (57:24) There is a battle playing out inside your body right now. It started billions of years ago and it is still being fought in every one of us every minute of every day. It is the story of a viral infection - the battle for the cell. This film reveals the exquisite machinery of the human cell system from within the inner world of the cell itself - from the frenetic membrane surface that acts as a security system for everything passing in and out of the cell, the dynamic highways that transport cargo across the cell and the remarkable turbines that power the whole cellular world to the amazing nucleus housing DNA and the construction of thousands of different proteins all with unique tasks. The virus intends to commandeer this system to one selfish end: to make more viruses. And they will stop at nothing to achieve their goal. Exploring the very latest ideas about the evolution of life on earth and the bio-chemical processes at the heart of every one of us, and revealing a world smaller than it is possible to comprehend, in a story large enough to fill the biggest imaginations.
You may be familiar with molecular movies from my two previous megaposts collecting them, but this extended documentary uses original animation that is collected into a coherent educational narrative and is just so fucking gorgeous. Enjoy.

Humans are less human than we thought.

Icky face-pooping flesh mites are only the tip of the iceberg. You've heard that your gut bacteria are necessary to help you digest, meaning not all germs are bad. Without them, we couldn't digest healthily. But stop and look at how far our interconnectedness with other forms of life goes: 1. Human DNA itself is at least 8.3% ancient viruses; without one of these viruses you could never have been born. 2. Mitochondria in human cells originated when the same type of bacteria that causes typhus disease raided one of our cellular ancestors and instead of hijacking it was pressed into service. (The same origin as chloroplasts in plants from cyanobacteria). 3. Far more of the cells in your body are non-human microorganisms than actual human cells. This relationship is not just interconnectedness. This is integration. [more inside]

It's life, Jim, but not as we know it

Could the three established domains of life - eukaryotes, bacteria and archaea - be joined by a fourth?

Why are evolutionary biologists bringing back extinct deadly viruses?

Darwin's Surprise. "There may be no biological process more complicated than the relationships that viruses have with their hosts. Could it be that their persistence made it possible for humans to thrive?" [Via Disinformation.]
