I had several people ask about how the IR-SENSE film works with smartphones. This video by @RogerSeheult offers a great summary and a direct link for the discounted @medcram price. youtube.com/watch?v=PLJrvn0u…

Cancer cells have a sneaky way of fooling the immune system:
They hijack the wiring of NF-κB to make it look like there's healing tissue instead of a giant blob of cancer that keeps growing.
This pathway also keeps releasing inflammatory cytokines and calls for immunosuppressive cells that will further help advance its growth.
The interesting thing?
Melatonin looks very promising when it comes to intercepting this pathway. Red/NIR PBM also seems to have an effect here.
To me this looks like another win for sunny day and dark night maxers.

I have a challenge for everyone here.
Let's see who can get Grok to correctly annotate the spectral chart of the sunset. It's a simple task of drawing lines that any child should be able to do.
For some reason, Grok can't seem to do it no matter how many times I try. Maybe it's just my style in how I phrase the request. Here's the best I got.

This looks interesting because EML is what actually matters when you want to eliminate ALAN.

You can also retrofit any LED bulb to produce a full spectrum with continuous NIR fairly inexpensively. Check out this video on how that's done: youtube.com/watch?v=VrxHdK15…
Spectrum of the sunset over the ocean.
When the sun is low on the horizon, sunlight travels through more of the atmosphere, and the blue light is significantly scattered, leaving mostly the longer red and near-infrared (NIR) wavelengths.
The red/NIR absorption (telluric) lines are also stronger because some of the longer wavelengths are further attenuated by more water vapor and oxygen in the Earth's atmosphere.
