Abstract: Apparatus and methods are described for use with feces of a subject that is disposed within a toilet bowl (23), and an output device (32). One or more light sensors (60, 62, 64, 66) receive light from the toilet bowl, while the feces are disposed within the toilet bowl. A computer processor (44) analyzes the received light, and, in response thereto, determines that there is a presence of blood within the feces, and determines a source of the blood from within the subject's gastrointestinal tract. The computer processor (44) generates an output on the output device (32), at least partially in response thereto. Other applications are also described.

Abstract: Application of a new light-molecule interaction in which molecules enable emission of photons with more energy than that of the absorbed photons achieves higher resolution than fluorescence imaging. This emission phenomenon is termed supracence and is applied to obtain more information about the structure and properties of a specimen than currently possible with fluorescence imaging techniques. Because supracence originates from chemical bonds, any structure that contains chemical bonds meets the necessary condition to potentially emit supracence. Super spectral resolution images are achieved by selectively exciting a target molecule to suprace without exciting another fluorophore that has absorption and emission rather close to the target.

Abstract: A system for biomolecule identification by terahertz sensing, an asymmetric triple split-rectangular (ATSR) metamaterial biosensor, and a method for biomolecule identification by terahertz sensing are presented. The asymmetric triple split-rectangular (ATSR) metamaterial biosensor includes three gap areas which highly confine an electric field.
