Yeah, many immune cells have a built-in circadian clock, like a lot of cells in our body. But there's some immune cells that don't even live a full day. Scientists wanted to know if they could tell time.

Well, a different group of researchers used baby zebrafish, which are transparent, to watch how fluorescent bacteria interacted with fluorescent neutrophils. And they found that neutrophils can indeed tell whether it's day or night. We talked to immunologist Chris Hall, who was part of that research team.

Or scientists could look at how to do the opposite. So like how to modify these clock immune genes to lower inflammation.

Yeah, they embedded tiny microscopic particles in contact lenses that convert certain wavelengths of infrared light to specific wavelengths of visible light. So using a few versions of these particles, they could convert a range of infrared light into different colors.

And Ari, one really cool thing, it kind of blew my mind about these contact lenses, is that participants could see infrared light when their eyes were closed. And this is because the longer wavelength can actually go through eyelids.

Well, as we mentioned before, these won't pick up infrared in like the environment just yet. So scientists need to work on their efficiency, like turning infrared to visible light. But if they could do that, one advantage of wearing them would be able to see when it's foggy or if there's low light.

For example, if you're like driving across a bridge when it's foggy, infrared light can travel farther like without scattering on fog particles.
