It's hard to source these claims scientifically, but let me try anyways.
In the following picture, the brain is below the tentacles and the eyes:
In all of the mentioned movies that part is gone.
The brain is gone in all of the videos, so the squid is definitely dead. So why does it move its legs? ...
The short answer is yes, plucking feathers causes a pain to birds.
First, can bird feel pain?
This compendium explains:
It is generally accepted that birds perceive pain
similarly to mammals. Birds have neurologic
components to respond to
painful stimuli and endogenous antinociceptive (antipain)
mechanisms to modulate
pain, and some ...
This scientific article states that a mutation in the MC1R (which is what causes red hair) can also cause some sort of pain reduction, as well as a lesser sensitivity to anaesthetics.
Results: C57BL/6-Mc1re/e mutant mice and human redheads—both with non-functional MC1Rs—display reduced sensitivity to noxious stimuli and increased analgesic ...
This is nothing but trickery. In this particular case, it appears that they have a liquid in there that has a much lower boiling point, is heavier than the oil, has the same appearance as the oil, and it is boiling to give the appearance that the oil is boiling. In this particular case, lemon juice is the common liquid used.

have there been any scientific studies conducted on this subject?
It seems that certain types of headaches can be relieved by certain types of massage
The article Massage Therapy and Frequency of Chronic Tension Headaches says
Objectives. The effect of massage therapy on chronic nonmigraine headache was investigated.

There's a lot of literature on this apparently, and I've only looked at one (55-page) 2018 NBER paper. There is some (correlational) evidence that the "pill mill" crackdown contributed to the switch to heroin, although this paper favors the oxy reformulation as the key event.
We attribute the recent quadrupling of heroin death rates to the August, 2010 ...
Most likely yes, plucking feathers from a live bird causes the bird pain.
There is a problem of existence of 'animal pain', and if we agree that animal pain exists, of whether the action of plucking feathers causes pain.
Does animal pain exist? It is obviously difficult to know first hand what an animal is thinking or feeling -- or even if it does think ...
A study has found that, even when caught on a hook and wriggling, the fish is impervious to pain because it does not have the necessary brain power.
The research, conducted by a team of seven scientists and published in the journal Fish and Fisheries*, concluded that the fish’s reaction to being hooked is in fact just an unconscious reaction, rather ...
If the question is whether CRNA Alice Magaw used hyponosis as the sole anaesthetic as implied in the article linked to by your question, then the answer is, no. She talked to her patients to quieten their fears reassuring them whilst administering chloroform or ether. The paper she wrote describing her method of administering these gases can be read in ...
There is an article (not peer-reviewed though) that I personally like that goes into science behind our current understanding of biopsychosocial model and cites a lot of primary literature (peer-reviewed).
Answering your question will require citing this article or similar work, but to assist in understanding this problem, consider that currently we don't ...
Reflexology is a pseudoscience.
Reflexology is based on an absurd theory and has not been demonstrated to influence the course of any illness. Done gently, reflexology is a form of foot massage that may help people relax temporarily. Whether that is worth $35 to $100 per session or is more ...
According to A Cartesian Introduction to Philosophy (1986):
This shows, by the way, why it's so pointless for you to pinch yourself to see if you're awake. You may dream that you are pinching yourself, and you may dream that you are finding yourself to be awake. Of course, if you are just dreaming that you are doing this, you are mistaken. In light ...
