biosights: November 25, 2013 - Caspases work as branch managers

submitted by: JCB
When a growing axon nears its target, it arborizes, or branches, to form numerous synaptic connections. Campbell and Okamoto reveal that localized caspase activation downstream of Slit-Robo signaling promotes arbor dynamics and restricts arbor growth. This biosights episode presents the paper by Campbell and Okamoto from the November 25, 2013, issue of The Journal of Cell Biology and includes an interview with lead author Douglas Campbell (formerly at the RIKEN Brain Science Institute,...

History of Medicine. Plague and Vampirism in the Middle Ages.

submitted by: camdic
The Nachzehrer would be a special kind of vampire who lives in a constant state of numbness in his grave, without understanding what is happening around and just like a child, chewing spasmodically his dress. Martin Böhm wrote in 1601: "We have seen in times of the plague how dead people especially women - who have died of the plague make smacking noises in their graves, like a pig that is eating, and that while this smacking is going on the plague becomes much worse, usually in the...

MWV #81 - Sheldon Campbell - The Singing Microbiologist

submitted by: MicrobeWorld
Sheldon Campbell sings about microbiology. Dr. Campbell teaches microbiology at Yale School of Medicine and he uses music to enhance his lectures. He has one song for every block of lectures he gives on a major topic. Songs he's written include a song about fungi, tick borne disease, tuberculosis and one that reviews all of microbiology in eight minutes. Dr. Campbell hasn't done any testing to see his songs are more effective at getting his message across but he does get the occasional...

biosights: October 28, 2013 - A framework for understanding muscle microtubules

submitted by: JCB
The microtubules of skeletal muscle fibers are arranged into an orthogonal grid, but how this network is formed is unknown. Oddoux et al. reveal that the network is built by dynamic microtubules nucleated from Golgi elements. This biosights episode presents the paper by Oddoux et al. from the October 28, 2013, issue of The Journal of Cell Biology and includes an interview with senior author Evelyn Ralston (NIH, Bethesda, MD). Produced by Caitlin Sedwick and Ben Short. See the associated...
