Foldscope paper microscope can diagnose malaria, costs 50 cents – Technology & Science – CBC News

I am always amazed at how imaginative people can be.  The TED.com blog is full of stories and videos of interesting people with amazing things to say; and so are universities.  You will find a number of entries on my blog site that are based on something amazing that has been developed for the third world by the folks at MIT.  This entry is about an idea originating at Stanford University.  I came across it in an article by CBC.CA (Foldscope paper microscope can diagnose malaria, costs 50 cents – Technology & Science – CBC News)  that explains how Professor Manu Prakash came to create a microscope made almost entirely out of cardboard that can be used to diagnose a multitude of diseases like sleeping sickness, malaria and schistosomiasis in the developing world where access to laboratory equipment is extremely limited.

Imagine if everyone that contracts one of these debilitating illnesses could be quickly diagnosed and treated!  This is the type of story that I love to see because it opens up the mind to all sorts of opportunities.

The original CBC story describes the microscope better than I can, so I won’t go into the details here, but I do also want to post the direct link to Dr. Prakash’s TED talk so that you can see him and his invention. Hope you enjoy it as much as I did.

Exercise – not only does it save energy, but it saves you too!

You may think it a bit of a stretch to link exercise to the environment, but I think it is pretty appropriate.  What got me thinking about it was an article on CBC.ca that pointed to the following YouTube video.  I hope that after watching the video you agree with me.

The video is by Toronto’s Dr. Mike Evans and as CBC’s article pointed out, it has gone viral on YouTube (it has now had over 1.6M hits).  Both the video and the article about it on CBC.ca refer to the health benefits of exercise for all of what ails you (hence the name “magic pill”).  The video is reminiscent of the videos on the “Story of Stuff” channel on YouTube.  While doctor Evans makes his very compelling argument in favour of exercising at least 30 minutes a day (and he notes that more is better to a limit) he draws images on a whiteboard that capture your attention and make you want to listen to the message.  I am not certain if he is any way associated with the Story of Stuff people, but the style of drawing and the humourous and interesting facts he injects into the discussion sure remind me of their excellent environmental pieces.

What interested me most was the fact that even the most moderate exercise (only 11 minutes per day) provided a huge benefit to many of the body’s critical systems.  The first 30 minutes of exercise seems to get you the biggest bang for your sweat buck.  After 30 minutes the benefits accrue in decreasing amounts, but they still accrue. 

Want to find out what sorts of problems you can alleviate with the magic pill of exercise?  Take 6 minutes and watch the video.  You won’t regret the investment in time… I sure didn’t.  You will instantly see why it went viral.  Send a link to the video on to your loved ones. 

Oh, what was the tie in to the environment you ask?  Well, if you are walking, running or cycling everywhere, you aren’t burning fossil fuels, and I think we can all agree that lowering your carbon footprint benefits the environment.

As a final postscript, remember to keep checking back to the “Story of Stuff” channel to see if they have added anything new.  Their environmental stuff is fantastic and it is great for all ages.

And thanks again to CBC.ca for providing me with another excellent learning experience.
