So by day, the immune system is primed to fight potential invaders, which it does by causing inflammation and And at night, it goes anti-inflammatory to recover.

This is immunologist Jennifer Hurley at Rensselaer Polytechnic Institute. She's talking about a special immune cell called a neutrophil that's really important at fighting off infections. And she says scientists hadn't really studied circadian rhythms in neutrophils because they die so fast.

Yeah, so Chris says they're interested in seeing if they can freeze neutrophils in the daytime state. In the case, for example, you have a really bad infection and need all hands on deck.

Kind of, but with some big caveats. So right now, these prototype lenses aren't very sensitive. They can only pick up infrared light sources in the lab, so not out in the real world from a person or a car engine. But the lenses do have some advantages. They're less bulky than night vision goggles, and they can be worn in the daytime.

And the big difference is that the contacts convert infrared into color vision instead of the mainly green or gray that night vision goggles do.

but the images they saw were blurry. And that's because the direction the infrared light was originally traveling gets lost when the contact lenses convert it to visible light. So that means making out the shape of the object also gets lost.

So the researchers coupled the contact lenses with eyeglasses, and the eyeglasses were able to focus the infrared light in a way that participants can make out letters and shapes. And they described all this in the journal Cell.
