A new wonder drug to replace sunlight?
I suppose that might be very useful in space or in some of the rainzones.

Find what wave lengths trigger the chemical reaction producing vitamin D and you might be able to synthesize something or for sure make UV lights more efficient at replacing sunlight.

I suppose some test animals in special cages which each blocked out certain wavelengths, while passing others could come in handy for this type of research.

I suppose if one could find out what other chemicals are produced in the vitamin D reaction - when taken they might trigger a "conditioned" response that produces a certain amount of vitamin D.

Are you there in the group picture at UCR?

Your cryptic posting style is always fun...
