The negative curve conjecture states that there is lower bound depending on a given complex projective surface
for the self intersection of an effective curve
on
. In this talk I will survey some recent work on this conjecture. By the end of the talk I will describe some work with M. Stover which shows that there is a universal constant t with the following property. The number of

and arithmetic genus less than
