Considering oxidation reactions are exothermic, and there’s HCl in the air from Ohio, is anyone asking about the photocycle of HCl in the presence of Ni+? I wonder how much Nickel is in the atmosphere from all the electric vehicle production in Ontario #ONStorm #ScienceIsCool 
Wow! So much fun being a scientist and still learning cool stuff after all these years. What colour is milk? (see thread for some #homeschooling experiments about blue skies and red sunsets with a bottle/glass of milk) 1/9
I was doing some research for a new text book on #EarthObservation (via @SpeckledPress ) by reading my very old (25 years?) “Flying Circus of Physics” (an excellent book, by the way) and it had an experiment that showed Rayleigh scattering using milk. Milk!?...🤔

But milk is an optical/geometric scatterer. No wavelength (λ) dependence. That’s why it’s white — it scatters all incoming light equally, regardless of wavelength.
Surely everyone knows that!?

There are 30 types of blindness caused by cone-rod dystrophies. Scientist have now created light-detecting cells from skin cells and injected them into 🐁 to partially restore their night vision... @nature #scienceiscool 1/3
The work from @UNTHSC is the first to show mitochondrial-to-nuclear signaling via free-radicals (like powerplants emailing the government) is VIP for cellular reprogramming...2/3 @PBTEXAS go.nature.com/3adnDx0
Their 5-chemical🍸induces free-radicals (mROS) in mitochondria, which activate inflammatory protein NF-kB, which turns on reprogramming genes, which convert skin cells into rod cells for injection 👁️💉 -- proving free-radicals aren't all bad! 3/3
