Science Facts & Billboards

A friend recently brought my attention to this link which contains 25 billboards by a Vancouver organization called Science World and I found the billboards to be insanely creative. So I figured I’d share some of them with you.

 

You can check out the rest of the billboards here.

And to make things a little more interesting, I’m going to explain the last billboard more. When you are scared, your body activates part of your autonomic nervous system called the sympathetic nervous system. This system is responsible for the three Fs (flee, fight and mate – you can substitute that last one with its F equivalent).

So the sympathetic nervous system prepares your body to either flee or fight in the same way. Part of this preparation is to cause pupil dilation in order to take in as much light as possible.

P.S.: you also see better when you’re aroused.

 

Memorial Hermann, a Houston Hospital, Live-Tweeting Brain Surgery

The day has come where Twitter is used effectively as a learning tool in medecine. Memorial Hermann, an institution based in Houston, Texas is currently broadcasting updates and answering questions during a brain surgery that’s going underway right now. You can check out their Twitter account here.

As a sample of what they’ve been talking, I took the following screenshots:

They’ve also tweeted a few pictures live from the operating room, as well as a brief video of the brain while they operated on it.

I think this is great. While I am familiar with some of the terms they’re throwing around, I think this a great educational opportunity for medical students, current MDs, and knowledge enthusiasts. I hope they do this again some other time as well because it sure is interesting.
