Well, a LOT of work and many studies have taken place since 1999,
many by careful researchers who studied specific aspects.
The melatonin/darkness connection is one that began being strongly
suspected in -- oh, gosh, it must be the late 80s or early 90s at the
latest. One of the first to suggest it was Dr. Judi Bell but sadly the
review boards for grants and she herself were at the time unaware
of the epidemiology work into melatonin (most at that time in
Scandinavia) or perhaps the study she proposed would have been
funded. (There is actually a marvelous compilation work from
Science News called something like "The Dark Side of Light"
which talks about the early work. The abstracts of numerous later
studies and descriptions of work can be found in the FHL
Archives. I well recall being called an idiot for suggesting the
importance of darkness until people saw references to the studies
in that compilation. There is more in the FML Archives.)
See:

but I am either not properly recalling the name of the article
or it simply is too early for the archives there
The body produces its own natural melatonin in response to enough
darkness. Dimness or fewer hours reduced that production. Blue
light is the most disruptive, followed by green. Amber is the least
disruptive.
High circulating levels of melatonin inhibit the body's production of
LH. High LH levels which can't be turned off by non-reproductive
sources (like the adrenals) of estrogens and androgens can cause
tumors to begin in the adrenals.
There are multiple other effects of melatonin, but it may well be that
that the one source which works best is the body's own, and certainly
implants seem to work better than oral sources often.
Multiple aspects of adrenal disease research beyond those mentioned
here can be found in Dr. Williams' article in the current issue of
Ferrets Magazine, and that is a recommended read...
