That's a working hypothesis:

 

lol, nice to see not too far off from what the real researchers are thinking.

Obviously phagocytes exist so perhaps other cells can use the same method to engulf them when needed. Possibly they have some means to 'infect' a cell themselves too.

Yes, but they show than we have free mitochondria are present even in physiological state.

So it must be usefull in another way, no ?

Possibly.

I know if I had my choice I'd use them to help repair/replace other mitochondria that have suffered damage, but I don't know if such a mechanism actually exists. We do know their distant ancestors entered the ancestral cell at some point however.

Reading that it was previously found that platelets release them to promote inflammation. They are descendants of bacteria, so pretty logical that they can still trigger an immune response.

It would be an interesting exercise to work out how much energy you would need to extract to cause, say, an extra leap second to be needed.

It would be. I'm sure it'd take a ton to speed up that process. I've read a few analysis saying we could power our civilization for a thousand years with just a bit of that energy.

...tides are created by gravitational pull of the Moon..

Slowing down the Earth's rotation among other effects. Trading is okay, stealing is not.

Unfortunately you can't steal energy from gravity(buoyancy = weight of displaced fluid). Going to at best break even, but will likely take more energy overall than you get back out.

The cost of the lithium polymer jumper was $79.7...not much different than a new lead-acid battery.

Recycling lead batteries is not not normally a factor in auto manufacturing (secondary smelters are the ones who deal with that), so why would an auto manufacturer care?

Provide the specs or name of the jumper. Not giving enough info to fully compare.

The manufacturers save money buying the cheaper nigh endlessly recycled batteries. Most lithium car batteries are roughly $100 more. Now multiply that per car sold...

Likely has a shorter lifespan or other undesireable characteristics.

Main thing is that lead acid battery is mostly recycled material. You don't have to mine or ship as much material, keeping costs down.

You can desulfinate or recycle lead acid easier.

In labs, researchers typically only modify existing viruses.

The smallest viruses in terms of genome size are single-stranded DNA (ssDNA) viruses. Perhaps the most famous is the bacteriophage Phi-X174 with a genome size of 5386 nucleotides.^[2] However, some ssDNA viruses can be even smaller. For example, Porcine circovirus type 1 has a genome of only 1759 nucleotides^[3] and a capsid diameter of only 17 nm.^[4] As a whole, the viral family geminiviridae is only about 30 nm in length. However, the two capsids making up the virus are fused; divided, the capsids would be 15 nm in length. Other environmentally characterized ssDNA viruses such as CRESS DNA viruses, among others, can have genomes that are considerably less than 2,000 nucleotides.^[5][6]

The smallest RNA viruses in terms of genome size are small retroviruses such as rous sarcoma virus with genomes of 3.5 kilo base pairs (kb) and particle diameters of 80 nanometres (nm). The smallest double-stranded DNA viruses are the hepadnaviruses such as Hepatitis B, at 3.2 kb and 42 nm; parvoviruses have smaller capsids, at 18-26 nm, but larger genomes, at 5 kb. It is important to consider other self-replicating genetic elements, such as satelliviruses, viroids and ribozymes.

This pandemic is understandably putting people on edge. Bad time to ask about how to make one yourself.

Should really look into taking some of the free courses out there or buying a synthetic genetics/molecular biology kit if this is of interest.

Link to a supplier as an example: https://amino.bio/

That has been observed to occur. In one case I read about, they think it was due to a prolonged supernova.

Fusion reactors in the sky.

That is a good point. At least part of the brain activity will be related to muscle activation.

Form the paper:

https://www.nature.com/articles/s41593-020-0608-8.epdf

But as most of the same areas of the brain are activated even when people talk to themselves (without vocalising) it still has interesting possibilities.

But this does mean that it is definitely going to be language specific, rather than "conceptual". Although perhaps other techniques (fMRI perhaps) could be used for that.

Probably nanika/nanka = something/thingummy/whatever

Right. See similar for people paralyzed or missing limbs using interfaces.

Have to caution not to go too far down the rabbit hole as the person has to be Speaking.

It could be easily picking up on what is being sent to the muscles.

There are wakefulness promoters, but nothing like the fanciful Limitless pill.

Incorrect or lack of grounding can result in the chassis to build up a charge along with everything connected to it(including the strings). Button works via running a small current through your skin so touching it is likely completing a circuit for the charge to flow out while the phone is charging.

I'd look at what type of plug the guitar has and possibly check that the wiring for the building is correct. Can be a safety risk. I recommend seeking someone local to ask about it when you are able.

If you search for bald monkeys and apes you'll see plenty of evidence for it being part of normal development.

Not to say you can't want to change it based on cultural beliefs, but the fact that you are fighting your own biology is something to keep in mind.

What is or can be an argument for immortality? 

Why die due to imperfect maintenance?

Still crude but they have found they can erase epigenetic damage.

Mothers can gain cells that turn into  neurons from their children so adding to the brain is doable in theory. No idea how a larger scale version impact the mind however.

Not sure keeping the mind the same is really even feasible in the longterm as new memories keep being added.

We'll probably need to add defect free clone cells while limiting the numbers of defective cells in the body. In theory just need everything to stay the same. Complexity of the task is the daunting part.

I like using a bookmark for 'Unread' myself. Avoid cluttering up your feed that way.

Additional filters are available too if you want.

I've found games gloss over a ton. Lack of mechanical failures are particularly noticeable.

Books like the Bible, which are meant for moral guidance ( not historical account ) usually reflect the morals of the times they were written.
The Old Testament part is much more violent than the New Testament, wherein the only time Jesus gets mad is when he upsets the money-lender's tables in the temple, and, he asks his Father to forgive his crucifiers.
This reflects the change in moral values that had occurred.

I would expect a 'Modern Testament' ( if one were written ) to have much different messages/guidance, especially in relation to the treatment of women, homosexuality, certain 'sins', treatment of the poor, etc.

Just to note, they were Money changers, engaged in the business of currency exchange.

My query was not about "Using vaccines to prep the immune system" . By "vaccines " , I assume you mean  synthetic vaccines (shots!). 

If humans only recently discovered immunization via shots and nasal sprays, then Nature might use similar strategy  . At least via physical contact, body fluid exchange,  snot, etc. See my orig. query.

Look into macrophages.

Immune system may inactivate some via fever and eats any it finds, but you'll still have functional viruses floating around.

Using vaccines to prep the immune system is better really.

Acetic acid, at concentrations high enough to affect the glue will really trash your skin.

True.

Just happened be a quirky side use I heard of while looking into it. Being able to make Cocaine play-doh is another weird one.

I'd recommend gloves either way lol.
