And some of these result in molecules that are in some excited states and they decay.

And a very small fraction of those emit a little bit of light.

So we can say that this is linked to metabolism, more specifically for those in the no reactive oxygen species.

And so really, it's a matter of measuring how much we metabolize.

And obviously, when we die, we don't metabolize.

So that thing goes away.

But there's also other things that create reactive oxygen species or other similar free radicals, and that could be stress responses.

So, you know, that's another part of the study is to look at, well, in leaves specifically,

Do they respond to stress?

Does this emission respond to stress, for example?

So that's the unsexy.

It's like mixing two chemicals together and seeing light, but something that's linked to the presence of life and metabolism in living beings.

Well, I mean, it depends who you're looking at.

When I look at my partner, I see a very bright light.

So shout out to her for that.

That's very sweet.

You know, it is extremely, extremely faint.

It's below the level that we can perceive with the human eye.

So when we do the experiments, we have a camera, this ultra-sensitive camera.

We put it in a dark tent where no lights are on.
