Scientifically, what exactly constitutes „death“?

When a living system(or its essential element(s)) can no longer longer function to interpret information and as a system loses its orientation towards homeostasis, and energy is freed.
The crucial part here is dysfunction, phenomenal life is dependent on biosemiotics to function, orientation towards homeostasis(the biophysical product of biosemiotics) is only lost after the system is already dysfunctional(dead)

When the soul leaves the body.

My best guess I meant to add before this, it's sort of hypothetical. Though its easy to reason that the loss of the logical elements of life are what causes it to dysfunction and thus lose its identity.

I guess loss of higher order functions. Death on a cellular level doesn't happen until a few hours after death as we know it. You can culture cell samples from a dead organism after death.

It's more "legal" than metaphysical. You have to draw a line somewhere. Sometimes a lot of money is at stake depending on whether A died before B or B died before A.

Definition has changed over time, Used to be "not breathing", then "no pulse", most recently "brain flatlined".
With the technology you mentioned, "death" may still be what we consider it to be today but they may add a footnote saying "temporary".

Personally, I consider irrevocable loss of memories and personality (say, due to destruction of neurons) to be
"death". Might be plenty of life left in the organism but that's not a "person" on the table.

im not trying to put you down or anything but im genuinely curious about why you think about life the way you do. It seems alien to me. How can you be so anthropocentric? The vast majority of life isn't human. Have you grown up surrounded by nothing but concrete and other people. laws arent even real life, they are completely abstract and are based on convention and authority, not nature. Money? what does any of that have to do with life and death, do you think there is a difference between a human dying, and a different form of organism, per se a tree dying?
Its mind boggling how so many humans are completely unaware of their actual place in this world, we are going to go extinct of loneliness in the future.

When will science prove that the soul exists?

Report, sage, hide the thread and move on.

As far as I've been taught, at least on a cellular level, its very hard to define death. Clearly one can distinguish a dead cell from a living cell, and one can see a cell is stressed/dying - but I don't think there's a clear answer as to at which point along that path from healthy > dying > dead, that death occurs.

For animals and such its a little more obvious, as other people said, its probably just where cognitive function and homeostasis ends

i am rather ignorant of microblogy but i assume cell death occurs when a cell no longer preforms its essential functions, such as interpreting genetic code as well as other more particular things, then this causes higher order processes to discard the cell in multi-cellular organisms.
i suspect my thoughts here to describe life in general,.

The definition of death has been hazy medically because it used to be when the heart stopped beating but obviously that's not really a good metric as we now know. Before that it was the lack of signs of life. Currently it's when you're brain dead, brain death isn't something anyone has come back from without significant damage. No one has come back from full brain death.

Cells rarely just die, often when they begin to reach a state of insufficient function they will, through either internal or external pathways, signal a process that results in their "death". For example cells undergoing oxidative stress will trigger their own death through "apoptosis".

Obviously causing a cell to lyse completely destroys it and skips this, but in general cells will kill themselves before they die.

It's because of this I said that its hard to pin point exactly where death occurs in a cell - the end result is clear - but at what threshold does the cell "decide" (for lack of a better word) that it is dead?

When someone posts on Veeky Forums they are biologically dead since they chances of procreating drop to zero.

some dude told me it's when you become a closed system

Ain't it the truth.

define "constitutes", then we'll talk, brainlet.

In a scientific format I guess, death would be when the outflow of the small electric currents created by the brain and the heart are ceased. Consciousness is only created when the brains synapses are sending electrical charges. A heart other than the brain is the only organ that can create its own electric pulses the time your heart beats causing it to contract pumping the blood in essence death is only when the brain is no longer pushing out a registered amount of electricity which can be measured with an EEG and heart is no longer putting out a static charge which can be measured with an EKG.

Not having qt creepyfu gf.

This tbqh.
More generally, not having a GF.

The medical definition is that all brain and brainstem activity has ceased. This means the individual can no longer think, plan, or willfully execute action. It also means the body cannot regulate the cells to the coordinated action that sustains the cells in all the tissues of the body.

In a more condensed sense it's when you can't do anything anymore, a lack of power.
