There's plenty of scientists doing studies like this. This is a new breakthrough as it allows the body to be brought back to life 20 minutes after death and sometimes up to 40 minutes. The heart stops. The brain will stop about 30 seconds after the heart stops.
Of course these experiments do not support any specific religion. They don't know what's happening. Scientists can still believe in things they don't understand. In fact there's plenty of things scientists believe in but don't understand, from cosmology to quantum mechanics. There're all kinds of particles they predict, no proof or evidence of their existence, but most scientists still accept & believe they exist. If a scientist has some video footage they took that was clearly not produced by any camera anomaly, that scientists may not be able to prove it to the world, but at least they know it's true.
