Scientists making progress with techniques that allow for seeing through opaque materials

(Phys.org)--It has been a desire, if not a dream for many throughout human history, to create a device that allows for seeing through walls (ala Superman), inside the human body or through a shield so that the enemy can be seen without risk. Surprisingly, over the past several years, scientists have begun to find ways to do such things--this week author/journalist Zeeya Merali offers a News Feature in the journal Nature outlining research in this area and where she feels it might be heading.
