Treating the Bends

ResearchBlogging.org
Last week I wrote about the Bends, a medical problem based in an understanding of physics that results in bubbles of (primarily) nitrogen in your blood if you move from one atmospheric pressure to another to quickly, typically surfacing from depth while diving too fast.

Of course I meant to point out that decompression occurs when the external atmospheric pressure drops quickly. Most commonly this occurs in divers but also happens in astronauts. I’d never really thought about that before.

Anyway I got as far as explaining how it occurs last time. This time we are interested in how you fix it.

Physics + Medicine = The Bends

About a fortnight ago I was in the unusual position of teaching human biology to medical physicists and physics to medical students. Interestingly, during this overlapping week a disease came up in both tutes, a physics based medical condition.

Zombies Pt 2 (or how I distracted my students)

ResearchBlogging.orgLast week I mentioned how my students sidetracked me in a tute regarding introductions to the origins of life and in particular the acronym HOMR standing for Homeostasis, Organisation, Metabolism and Replication by initiating a discussion of whether or not zombies technically were alive. Well, the following week they had a test that occupied half the allocated tutorial time so instead of letting them out early I extended the discussion to real world zombies.

Zombies Pt. 1 (or how my students distracted me)

As I mentioned a little while ago I have been made an associate lecturer for first year biology at the University I have been doing my PhD at. Most of my job is taking tutorial classes and the other week during one of these classes I got totally distracted by a very interesting discussion.

Exploding Head Syndrome - No pun required

ResearchBlogging.org
This is an old post from my previous blog. Recently it has been seeing a lot of activity so I thought I'd play around with it a bit and re-post it here. Enjoy :)

Sometimes when searching for disease to write about a wonderful thing happens. The clouds part, cherubs descend, angels play intricate harp-based musical compositions, and a beam of light illuminates the link to a wonderful disease. This happened to me the other day, and now, without further ado, let me introduce you to Exploding Head Syndrome. Best. Disease. Name. Ever.

Jumping Frenchmen of Maine Syndrome

Well I’m back! I’m not going to pretend like you missed me but I hope your glad to see another post out of me. I did a bit of writing during my time off to build up a bit of a backlog so hopefully I can keep posting regularly for a while. Anyway, without any further ado…

Jumping Frenchmen of Maine Syndrome

Best. Disease. Name. Ever.

This disease was first observed in 1878 by the neurologist Dr. George Miller Beard, a guy I will definitely talk about again, in French-Canadians, lumberjacks and presumably some French-Canadian lumberjacks living in northern Maine. So that explains the “Frenchman” and “Maine” parts but lets look at what makes this a “Jumping Syndrome”.
