Turning a Cell Phone Into a Microscope 50

stupendou writes with this excerpt from the New York Times: "Microscopes are invaluable tools to identify blood and other cells when screening for diseases like anemia, tuberculosis and malaria. But they are also bulky and expensive. Now an engineer, using software that he developed and about $10 worth of off-the-shelf hardware, has adapted cellphones to substitute for microscopes." But not based on optical magnification: the article explains that Aydogan Ozcan, a UCLA assistant professor of electrical engineering, has combined the wireless transmission abilities and imaging sensors now typical in wireless phones to make the phones capable of detecting cell abnormalities and more by capturing wave interference patterns from body fluids — like blood — and sending them on for analysis.

Update 20091108 15:03 GMT by timothy: Dave Bullock mentions this gallery he shot last year for Wired showing how a phone is hacked to add microscope abilities. "The new version looks a bit more polished, to say the least," he writes.

Can anyone expect a national patent system not to favor patents of domestic origin over those of foreign origin? Even if in the end, the foreign party wins, there is plenty of red tape that can be thrown in the way. At the very least, isn't this be considered a act of loyalty to the tax paying domestic patent holders?

It's another myth that aluminum cases are lighter - that may be true by a half pound or so...

Actually, metallic iron has a density of about 7 g/cc, and aluminum is 2.6 g/cc -- an aluminum case will weigh less than half an iron one made of the same thickness of material.

I can vouch for the lightness of my aluminum case. This isn't 40.0 vs 39.5 lbs, it's more like 40 vs 20.

Marty: Put it up to eleven.
Nigel: Eleven. Exactly. One louder.
Marty: Why don't you just make ten louder and make ten be the top number and make that a little louder?
[pause] Nigel: These go to eleven.
