Neurons let it slide

During mammalian brain development, many neurons migrate away from the site where they are born to settle in distant locations where they send out dendrites and axons to connect with other neurons. Both neuronal migration and axon/dendrite extension depend on forces generated by microtubule-based motor proteins such as cytoplasmic dynein. The effects of these forces depend, however, on the orga...

Let it snow! Let it snow! Let it snow! Estimating cocaine production using a novel dataset based on reported seizures of laboratories

Background: data on cocaine market appear to be inconsistent, as they tend to show declining prices vis a vis a steady or increasing demand and a declining supply. This paper proposes an explanation by providing evidence of an under-estimation of the supply of cocaine. Methods: we put forwa d a conservative estimate of cocaine production in Colombia for year 2008 by means of reported seizures o...

BACKGROUND Data on the cocaine market appear inconsistent, as they tend to show declining prices vis-a-vis steady or increasing demand and a declining supply. This paper proposes an explanation for this trend by providing evidence of an under-estimation of the supply of cocaine. METHODS We propose a conservative estimate of cocaine production in Colombia for 2008, using data based on all repo...

Let ’ s Call It the “ Ubiquitous Library ”

Framing an argument with the right terminology is critical to making any case effectively. Sometimes such framing is to clarify understanding, while in others it is rhetorical and persuasive. Politics is a particular example of the latter. Since at least 1984 when Duane Webster first developed and wrote “Organizational Projections for Envisioning Research Library Futures,” we have been struggli...
