I do like these summaries at the end of the year

Most worrying for me personally is the effect of being sleep deprived. Spray-on vanta black is the toy I want the most this year. I wonder when it starts showing up on cars.

If this paint absorbs so much light, does that mean that it's surface will heat up more as well?

Hence, if you painted a car with it, the car would get extremely warm inside when left in sunlight?

It has a very high emissivity, which means that it's both a very effective absorber AND emitter of radiation, therefore negligible net temperature rise.

Excellent read, thanks.
Not sure, most of it reads like a science version of the National Enquirer. The lungs being the main source of platelets would have huge implications for Leukaemia. The Siberia permafrost melting due to "climate change (tm)" when Siberia has the edges of the Eurasian Plate, running through it? wiki
I would hesitate before I listed these as "Facts" more like interesting findings if true, more research needed.
