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 megapostscollecting them, but this extended documentary uses original animation that is collected into a coherent educational narrative and is just so fucking gorgeous. Enjoy.
Have You Eaten Your Dirt Today, Honey?A New Approach To The Hygiene Hypothesis.The hypothesis argues: The reason why there is so much asthma, eczema, allergies and maybe even childhood diabetes in the modern world is because we — well infants really — live in too clean a universe. What our baby immune systems need is a kickstart by exposure to viruses, bacteria, worms, pollutants and so on. If you don’t get an infant hit from these icons of uncleanliness, the immune system goes haywire and your body over-reacts to all sorts of invasive things that normally could be ignored.Via.

Crocodile Immune System Kills HIV Because crocodiles fight amonst themselves and get seriously wounded from time to time they developed incredibly strong immune systems and natural antibiotics. So strong that they, well, let's hear from one of the scientists....
"The crocodile has an immune system which attaches to bacteria and tears it apart and it explodes. It's like putting a gun to the head of the bacteria and pulling the trigger," said Australian scientist Adam Britton. Sounds like good news to me.
