Beans functions of graphs with small beans
The beans function BG(x) of a connected graph G is defined as the maximum number of points on G such that any pair of points have distance at least x > 0.

Telomerase: The Devil Inside
High telomerase activity is detected in nearly all human cancers but most human cells are devoid of telomerase activity. There is well-documented evidence that reactivation of telomerase occurs during cellular transformation. In humans, tumors can rely in reactivation of telomerase or originate in a telomerase positive stem/progenitor cell, or rely in alternative lengthening of telomeres, a tel...
