When you're dreaming, the experience feels real to you. But you wake up and it turns out that it was just random neuronal activity creating a seemingly real experience for you. But what does that imply about our awake state? Are we just passengers along for the ride?

>> No.12420066

Dreams have less neuron activity than being awake does. That is why you are more "awake" and "aware" when you are awake. If your prefrontal cortex is having low activity in your sleep, your dreams will not be self-aware that much and you will simply watch the ride rather than be lucid. If more of your brain is active during a particular night then you will be lucid in the dream.

As far as I know, there is no known explanation for where the images and audio of dreams comes from actually. Memories are activated during dreams but strangely the part of the brain that is used for "imagination" and imagining imagery in your head is turned off during sleep, so people still have no idea where the images in dreams come from. Maybe it is just a byproduct of memories being activated? Nobody is sure.

People have "claims" about what dreams are for, but there is no concrete evidence for any theory of dreams right now, it is still just a mystery. The most credible theory is that it is just a byproduct of the brain being active during sleep and because it does not cause harm to the species there was no reason to remove dreaming evolutionarily speaking.

>> No.12420148

On a small scale like pipetting things yeah as long as you're not a dumbass you won't contaminate your media etc. but when you're pumping a large volume the chances of contamination go up exponentially, and once you've got some yeast or whatever in your media that's it you have to start over.

I'd say the time savings from using a cheaper/quicker pump that is more prone to introducing contamination is significantly less than the time youd have to invest starting over after you find bacteria goop in your precious bioreactor

>> No.12420208

There's basically no reason not to use a peristaltic pump for bioreactors. You have greater chance of avoiding biological and chemical contaminants (pump oil from mechanical pump will always leak for instance even if you don't get fungus or bacterial outbreaks). Considering you have the time to shitpost I doubt you are on such a strict time schedule that you can't use a proper pump.

No, your brain generally does plateau at 25 for males, but you remain at that peak until your mid 30s at least, and then only slowly decline until about 50ish. So you most likely will feel the smartest you've ever been around your mid 20s to your mid 30s.

Hear me out, bros.

I don’t mean that niggers will build doomsday machine or grey goo. They are obviously incapable of that, although they could steal or purchase the technology.

More likely though, on any planet with an intelligent species, a faster breeding but less intelligent subspecies takes over and eventually crowds them out. I think with all this Fermi Paradox stuff we take for granted that any human-like intelligence should evolve to be space faring. But I don’t think that’s the case. Although niggers are human-like, I could see them running the planet for tens of thousands of years of stagnation before decline, all the while never leaving earths gravity.

tl;dr: the world's population might go into decline from now until 2100. Can't tell if that's a good or bad thing, though.
Understanding potential patterns in future population levels is crucial for anticipating and planning for changing age structures, resource and health-care needs, and environmental and economic landscapes. Future fertility patterns are a key input to estimation of future population size, but they are surrounded by substantial uncertainty and diverging methodologies of estimation and forecasting, leading to important differences in global population projections. Changing population size and age structure might have profound economic, social, and geopolitical impacts in many countries. In this study, we developed novel methods for forecasting mortality, fertility, migration, and population. We also assessed potential economic and geopolitical effects of future demographic shifts.

Can't tell if this is a good or bad, though.

Why does drinking and sleep deprivation kind of make me feel better and almost like a different person, freer and truer, despite it also feeling awful? I'm a much more original thinker when I haven't slept while also being irritable as hell.

Am I too anxious? Am I depressed? Does this break through it? I often feel I'm in a permanent state of alertness and fear, it cloys my mind and stops me from doing much but distracting myself, escapism, and 'waiting' endlessly.
