Populations drifting apart

Plasmid partition: sisters drifting apart.

Remarkably little is known about how bacterial chromosomes and their plasmids are partitioned to daughter cells prior to cell division, despite extensive experimentation and bioinformatic analysis. An in vitro study described in the current issue of The EMBO Journal recapitulates many features of plasmid partition in vivo and provides insight into how protein patterning on the nucleoid, determi...

Drifting Apart? European Journalists and Their Audiences

Drifting together or falling apart? The empirics of regional economic growth in post-unification Germany

The objective of this article is to address the question of convergence across German districts in the first decade after German unification by drawing out and emphasizing some stylized facts of regional per capita income dynamics. We achieve this by employing nonparametric techniques which focus on the evolution of the entire cross-sectional income distribution. In particular, we follow a dist...

Moving Closer or Drifting Apart? Assessing the State of Public Opinion on the U.S.-Canada Relationship

"Living together apart": the hidden genetic diversity of sponge populations.

Intraorganism genetic stability is assumed in most organisms. However, here we show for the first time intraorganism genetic heterogeneity in natural populations of marine sponges. A total of 36 different multilocus genotypes (MLGs) were detected in 13 individuals of Scopalina lophyropoda sampled at 4 distant points within each sponge. All genotypes (showing a mosaic distribution), were transmi...
