The key to those sharper pics, it seems, is so-called "dark field microscopy, " a technique that, as NewScientist points out, is normally used by biologists.

Secondly, the relatively small cost will likely lower the barrier to entry for advanced microscopy and make field diagnosis an easier and more viable option in places like Africa.
