Traditional forensic methods to identify the time of death was based on changes in body temperature or the rate of decomposition of body tissues but these values could be easily miscalculated as what was happening before the individual's death cannot be immediately confirmed. However, finger-like projections in the nasal cavity lining the walls will continue waving even after death. Reportedly, since these cilia will continue but gradually slowing in their movements, the time of death could be pinpointed more accurately. More after the break.Nasal cilia are tiny projections originating from the olfactory bulb, and part of their major purpose is to sweep foreign substances which are beneficial to our respiratory off the nose and down the throat. Biagio Solarino of the University of Bari in Italy and his team speculated that cilia continue to wave even after its master's death. They took a scraping of the lining of the nose from 100 cadavers to examine the cilia and found the motility continues 20 hours after death, as observed. They hope to use cilia examinations to predict the time of death primarily due to the fact that the beating pattern slows gradually and besides being generally immune to environmental factors.
