We discuss some conjectural inequalities involving the sums sig_n(s) := 1^s + 2^s + ... + n^s. Two of our Conjectures assert that both a(s):=sig_(n+1)(s)/sig_n(s) and a(s)*sig_(n+1)(s)/sig_(n+2)(s) are strictly log-convex in s on all of the real axis. We will also present a common generalization of these two Conjectures. Various applications are described, to existing theorems as well as to some other unproven conjectures
