Scientific projects:

In recent years, significant progress has been made in forensic science through research led by young scientists in the fields of genetic and biochemical analysis. A noteworthy area of exploration is the study of costal cartilage, which has emerged as a valuable niche in forensic investigations. One ongoing project (2023) investigates the potential of costal cartilage as a new niche of human remains in the field of forensic acarology. This builds on previous studies, such as a 2022 project focused on correlating CT imaging results with the age of individuals in the Upper Silesian population. The investigation continues with the aim of enhancing forensic identification techniques using non-invasive imaging methods.

In 2021, a series of research tasks further highlighted the forensic potential of costal cartilage. One study examined the presence of psychoactive substances in postmortem cartilage, while another investigated the genetic and biochemical markers in human semen, even after laundering evidence. These projects have demonstrated how cartilage’s unique properties can aid in the detection of biological materials, preserving DNA integrity, and facilitating forensic identification, as documented in a National Science Foundation-supported study. Additionally, research from 2020 and 2019 expanded on the understanding of how decomposition affects psychoactive substance concentrations in cartilage, as well as its applications in age estimation of deceased individuals, making costal cartilage a vital area of focus in forensic science.
