Clustering is difficult only when it does not matter

Numerous papers ask how difficult it is to cluster data. We suggest that the more relevant and interesting question is how difficult it is to cluster data sets that can be clustered well. More generally, despite the ubiquity and the great importance of clustering, we still do not have a satisfactory mathematical theory of clustering. In order to properly understand clustering, it is clearly nec...

It is not only the cat that did it: how to prevent and treat congenital toxoplasmosis.

The apicomplexan parasite Toxoplasma gondii was discovered a little over one hundred years ago and was soon recognized as a pathogen responsible for congenital infection. But detailed understanding of its epidemiology emerged only after 1970 with the discovery of its life cycle. In the last ten years, high resolution molecular tools have allowed the characterization of various strain types with...

Like it or not, politics is the solution.

Over the 20-year life of the Society for Conservation Biology (SCB) huge strides in biological understanding have been made. Michael Soulé, one of SCB’s founders, recently noted that prior to the mid-1980s “there was virtually no awareness of edge effects, fragmentation effects, ecological sinks, extinction vortices, inbreeding effects in natural populations, habitat destruction in the seas, en...
