They did the telepathy with chess guy. There are two guys with neuralink installed now.
Now they're moving towards curing blindness. They just got approved for testing on humans. Patient registry is open.

I attempted to ask my neuroscience professor a few questions earlier, although I'm still not sure I fully understand. I'm hoping you guys can help.
1. How does an action potential work? I understand it as being the difference between the extracellular and intracellular voltages. In other words, the resting potential of -70 m/v describes the intracellular space as being 70 m/v less than the extracellular space.
But in order to reach the -55 m/v threshold to initiate an action potential, one would need to decrease the difference between the two (depolarize); in order for that to occur, one would either need to increase the intracellular voltage, or decrease the extracellular voltage. Only the latter (to my knowledge) is possible prior to the initiation of the action potential/the opening of voltage-gated ion channels, and I understand this process (of decreasing the extracellular voltage) as occurring due to an accumulation of Na+ ions.
However, these seem contradictory: How can one be decreasing the extracellular voltage when an accumulation of positive Na+ ions would, ostensibly, be doing the opposite (increasing the voltage)?
2. How do postsynaptic potentials (PSPs) — in the process of attempting to initiate or discourage an action potential — travel from a neuron's dendrites to its axon? Does it simply travel across the cytoplasm of the soma (although, if so, would the flood of ions traveling through affect the neuron's organelles)? Or are the traveling ions released into the extracellular space (and, if so, through what mechanism)?
3. In heterozygote individuals (one dominant allele; one recessive allele), are both genes on each chromosome pair expressed, that is, made into proteins? Or does expression only apply to the dominant gene?
If they're both expressed, manufacturing proteins which aren't used seems like a waste of energy — and, seemingly, would go against nature's tendency to prioritize efficiency.
Thank you!

Everyone is just a machine, operating on basic evolutionary psychological impulses to propagate their genes and remove competition. Just cogs and wheels of nitrocarbon protein nanomachines and mitochondrial batteries whizzing away, slowly falling apart. Most people don't even mean what they say and only promote morals or beliefs in order to conform to all the other machines. The minority of people who are actually conscious of their own humanity and who have risen above the baseline of instinctual conformity to fully embrace higher ethics are in actual fact, defective in the context of evolution - our gears aren't aligned properly, we empaths, we autists, we philosophers. From the perspective of evolution, the greatest values known to man are mere hindrances to selection. Good natured prosocial protein sacks in the form of Christian Missionaries try to help the poor in Haiti and are killed and raped by more aggressively configured protein sacks with African names. And those protein sacks replicate, not the sacks with self awareness and humanity and empathy for ones fellow man. Those are all snuffed out in order for the human race to fit more snugly into the cynical factory process of environmental adaptation and natural selection, with humanity tortured into shape like a bonsai tree to bear that which conscious life would otherwise rightly perceive as unbearable. It makes me so angry I want to vomit. I think if we want any chance of escaping this horrid darwinian existence, we need a means of destroying evolution, natural selection and nature itself - likely through gene editing. I don't see that happening in an ideal way if there isn't an extremely moral and humanity minded population with their hands on the technology, which the evolutionary competition adapted psychopath banker crooks most certainly aren't. I take pride in the strangulation of the process of natural selection, and the bastardisation of nature. Because nature and humanity are inherently enemies.

Is there a single real world situation where PEMDAS makes sense?
Usually the logistics of a complicated business operation has its own intrinsic bottlenecks that things need to calculated around making PEMDAS sort order irrelevant.

How would i be able to figure out the .75 decimal on measuring tape when i measure 15 3/4? I used a website to figure out 15 3/4 is 15.75. I just dont know how to count the .75 on a measuring tape.

Here's a typical pager battery. It can supply 3.8 volts and has a capacity of 2800 milliampere-hours, so the energy contained in the battery is 38.3 kJ. That's equivalent to roughly 22.5 grams of RDX, which has an energy density of 1.7 kJ/gram.
Short-circuiting the pager battery for a prolonged period of time can cause it to heat and swell up, building up potential energy until it explodes. This can release enough energy to account for the explosions we saw today.
The pagers could have been detonated remotely without any physical tampering.

Why are philosophy shills so weak mentally and inferior to scientists ? Has philosophy never recovered from a book published in 1687 ?

I'm from Kenya and I've never enrolled in education after the 4th grade, What's the proof that 1+1=2? if we assume that there is always some smaller building block than a molecule, an atom, and a subatomic particle if we could go forever and the smallest things are different from one another then there is not 1 thing equal to another 1 thing then there can't be any 1+1=2!

The thread we had yesterday on wearing aristocratic 18th century clothing in high crime/violence ghettos was POWERFUL, you usually can't find stuff of that quality on /sci/.
When I heard those gunshots go off in that Screwly G video I just imagined myself in that environment sipping tea with queen Victoria the first, with a rather smug and jubilant facial expression FOR SPRITUAL POWER. God is good for this.
For anyone who does not believe in God I can change your mind in just 5 minutes.
Step 1: Open this video: https://www.youtube.com/watch?v=kQn
Step 2: Picture yourself as the white boy posted in the OP image
Step 3: Imagine yourself in that environment in the Screwly G video gunshots blazing, an erratic and chaotic moment, however you're in pure bliss because you know you've come into this space wearing a SPENDID BLAZER and cravat from one of the most PRESTIGIOUS clothing stores from 18th century BRITAN you sip tea and socialize in your LARGE powdered wig and tell Screwly and his gang "Well, this is RATHER BODACIOUS I MIGHT ADD" while giving a CHEERFUL CHUCKLE and doing a mini breakdance move. Screwly and his gang then approach you and stare at you in a hostile manner. Visualize all of this together for a good 20 minutes.
VISUALIZE ALL OF THIS AND TELL ME GOD DOES NOT EXIST. DON'T JUST ASSUME I'M WRONG, TRY IT. YOU WILL BELIEVE IN GOD.

He currently has the most connections in the AI field and heads OpenAI. He delves into always being transparent and open to decisions made if he isn't a good CEO. When the board kicked him out for withholding important information on making literally the most powerful technology ever. He came back and got rid of the board members. In a Bloomberg podcast, puts his character into question. He always wants to be in charge. Lets his sister live in poverty and prostitution. Power hungry and very manipulative. I don't like him in charge of creating AI and being so hidden. No one seems to care either. He's very good at playing the game. What does /Sci/ think?
