The two 'Nobel Prize-potential' theoretical topics discussed in this article by the author, a practicing lawyer who deals with forensic science, but does not do any research. Clearly, the person(s) making the discoveries discussed in this article are not forensic experts but biologists, bio-chemists, physicists, etc., that is, persons dealing with basic science. 1) To make a step forward in the method of scent identification, a transparent, checkable examination method and accountable individuals who are also responsible for the results are necessary. This basic research tool is not at our disposal at present, but it could be the basis of prestigious international acclaim: and this is the description of human scent. The modeling of the molecular structure of scent would be worthy of the Nobel Prize. 2) The polygraph is a useful device in verifying different investigative versions, which some people call a lie-detector (or 'honesty-meter'). The problem is: the method of examination does not provide an answer to or explanation of the reason of this conclusion. Consequently, the result may get distorted, as the person replying might not be honest for a thousand of reasons independent of a criminal act (e.g. earlier personal good or bad experience, or to cover up for another person or another act). If one examines not the physiological phenomena of the person undergoing the procedure but the real thoughts and memories appearing in their brain. That is, it is not a body-polygraph we need, but a reader/scanner concentrating only (mono) on the brain (monoscanner). (Published Abstract)
