A hitchhiker's guide to survival finally makes CENs

Most strains of the yeast Saccharomyces cerevisiae contain many copies of a 2-microm plasmid, a selfish autonomously replicating DNA that relies on two different mechanisms to ensure its survival. One of these mechanisms involves the high fidelity segregation of the plasmids to daughter cells during cell division, a property that is starkly reminiscent of centromeres. A new study reported in th...

The Hitchhikers' Guide to Google

The web is big. Really big. This is good because the Web now encompasses the entire history, culture, science, and achievements of the human race, not to mention JPEGs of every romantically eligible member of that race under the age of 35. This is bad because it is now too big to find anything. The ‘Hitch-Hikers Guide to Google’ is a collection of patterns that will be your guide through the In...

A Survival Guide to Fission

The fission of a person involves what common sense describes as a single person surviving as two distinct people. Thus, say most metaphysicians, this paradox shows us that common sense is inconsistent with the transitivity of identity. Lewis’s theory of overlapping persons, buttressed with tensed identity, gives us one way to reconcile the common sense claims. Lewis’s account, however, implausi...

A survival guide to Landsat preprocessing.

Landsat data are increasingly used for ecological monitoring and research. These data often require preprocessing prior to analysis to account for sensor, solar, atmospheric, and topographic effects. However, ecologists using these data are faced with a literature containing inconsistent terminology, outdated methods, and a vast number of approaches with contradictory recommendations. These iss...
