Back of the envelope calculations for this post. An old press release for a paper on endocytosis by Tom Kirchhausen contained this fascinating factoid: The equivalent of the entire brain, or a football field of membrane, is turned over every hour If this is true it is absolutely staggering. Let’s check it out. A synaptic vesicle is ~40 nm in diameter.

I noticed something strange about the 2013 Impact Factor data for eLife . Before I get onto the problem. I feel I need to point out that I dislike Impact Factors and think that their influence on science is corrosive. I am a DORA signatory and I try to uphold those principles. I admit that, in the past, I used to check the new Impact Factors when they were released, but no longer.

I thought I’d share a procedure for rotating a 2D set of coordinates about the origin. Why would you want do this? Well, we’ve been looking at cell migration in 2D – tracking nuclear position over time. Cells migrate at random and I previously blogged about ways to visualise these tracks more clearly. Part of this earlier procedure was to set the start of each track at (0,0). This gives a random hairball of tracks moving away from the origin.

This post is about a paper that was recently published. It was the result of a nice collaboration between me and Francisco López-Murcia and Artur Llobet in Barcelona. The paper in a nutshell The availability of clathrin sets a limit for presynaptic function Background Clathrin is a three legged protein that forms a cage around membranes during endoctosis.

We have a new paper out! You can read it here. I thought I would write a post on how this paper came to be and also about our first proper experience with preprinting. Title of the paper: Non-specificity of Pitstop 2 in clathrin-mediated endocytosis. In a nutshell: we show that Pitstop 2, a supposedly selective clathrin inhibitor acts in a non-specific way to inhibit endocytosis.
