University of California researchers have discovered a way to convert evanescent (near-field) light waves into "normal" light waves so that they can be detected by standard microscopes. A recently-developed silver-film "superlens" is placed within 35 nanometres of the surface, and corrugations in the film's surface diffract the evanescent waves, converting them into normal light waves that can be captured using a conventional microscope. As a result, the system was able to distinguish two nanowires placed within 70 nanometres of each other, more than three times closer than is possible using conventional methods.Gadgets: Mummy wrap

A new Zealand company has developed a shirt, dubbed MummyWrap, that it promises to protect fetuses from electromagnetic fields, such as those associated with cell phones.Bear in mind that there is no evidence that the EM fields to which we are all typically exposed represents any real risk to a fetus. The shirt contains copper wire embedded in the material. The maker claims, despite evidence to the contrary, that the shirt will protect against EM fields generated by high-voltage power lines.
