T-ray breakthrough could make detecting disease far easier

... found that although ordinary metal wire would not guide T-rays very well, if a series of tiny grooves was cut into the wire, it would do so much more effectively. If such a corrugated metal wire is then tapered to a point it becomes possible to very efficiently transport radiation to a point as small as a...

Biologists call for better choice of model organisms in 'evo-devo'
