Spider Silk Lets Scientists See Like Never Before

Scientists who use conventional light microscopes--like the one you probably peered through in high school science class--face a limit on the size of objects they can view. Basic properties of light prevent them from focusing on anything smaller than the tiniest known bacteria.There is a work-around in so-called superlenses that perform clever optical tricks to shrink the size minimum by half, and sometimes even more. But superlenses are difficult and expensive to manufacture.Now, though, resear...
