Absolutely insane how this is actual reality. That millions of people have died from such a small object that seems to have more creativity and complexity than I’ve ever seen.

You might enjoy: Influenza A (H1N1) – How many bits does it take to kill a human? https://www.bunniestudios.com/blog/?p=353

Also, video: https://www.youtube.com/watch?v=NPr-i-IbA7s

This one is about Influenza: https://www.youtube.com/watch?v=7Omi0IPkNpY (not H1N1, but quality is better)

I learned a lot today (At least that's what I felt) LOL

+reproduction +selection

I haven't yet seen a good explanation as to why this focus on randomness is so prevalent, but chance really is almost irrelevant when it comes to evolution. The main mechanisms of reproduction and selection that you point out have almost no randomness at a population level. Selection of individuals has some randomness associated with it, as death can come unexpectedly to anyone, but at population levels it is the gen…

ENTROPY BABY.

A better animation is the winner of the AutoPACK challenge few years back: https://vimeo.com/62635232 Those guys did an awesome job because: a) use of brownian motion b) sick af music.

That's a poor visual of Brownian motion. Things don't giggle they randomly fly around at ~250 miles an hour.

It's still a great video just IMO misleading in its own way.

As a technologist, I have mixed feelings when I see the fascinating details of life. On one hand, mastering this molecular machine would give us literally God-like powers: we could fabricate, grow or heal anything. We could solve all current problems, we could terraform planets using a few milligrams of DNA and literally redefine what it means to be human. On the other, I see the human body as a completely unsecured…

Interestingly the Gene Regulatory Network (GRN) - the interaction of genes and proteins that control the prosess inside the cell is computationally very similar to recurrent neural network. Gene expression levels is controlled by proteins that are produced by active genes. https://en.wikipedia.org/wiki/Gene_regulatory_network

Harnessing this mechanism directly for neural computation would be grand project.

You can't really design a perfect virus that will wipe out the human race, because anything you do to affect its properties will also affect its ability to spread. I'd be way more concerned about the destructive power of nuclear weapons, still numerous enough to destroy a very large part of humanity and our vital infrastructures.

Hard to believe that no one has programmed this. Evolution is insane.

Seems that you are not a programmer. Even with Intelligence people can write code (much much simpler and buggy) how can chaos build such a complex thing? Can you answer what was first? information (RNA/DNA) or the first cell?

I Googled it for you: https://www.ted.com/talks/janet_iwasa_why_it_s_so_hard_to_cu... https://www.seeker.com/will-we-ever-cure-hiv-1792546668.html https://en.wikipedia.org/wiki/Management_of_HIV/AIDS Also you may interested: https://en.wikipedia.org/wiki/The_Berlin_Patient

>in the U.S. HIV kills 10,000 people per year I remember an early passage from Buckminster Fuller's Grunch of Giants where he tells the reader to visualize fully packed stadium and explains that's what 10,000 people looks like.

I'm not sure 10,000 packs a stadium in the US. Maybe the bleachers of a high school football stadium.

My favourite cell documentary is this. Has more information about the various transport mechanisms in the cell itself. Simply awesome - have watched several times to understand better. See https://www.youtube.com/watch?v=FzcTgrxMzZk
