Dr Ehlers was appointed to serve on the National Forensic Oversight and Ethics Board of 10 members for a second term, based on her knowledge in the field of forensic sciences.

Dr Karen Ehlers from the Department of Genetics at the University of the Free State (UFS) was elected as a member of the National Forensic Oversight and Ethics Board (NFOEB) for a second term.

Dr Ehlers has been appointed to the board of 10 members based on her knowledge in the field of forensic sciences. She is currently conducting research focusing on the forensic application of Y-STR markers, the statistical analysis of DNA profiles, and touch DNA.

Making valuable contributions
Her expertise in the field of forensic genetics assists the board – which also handles complaints about alleged violations relating to the abuse of DNA samples and forensic DNA profiles – to oversee the operations of the Forensic Science Laboratory and the National Forensic DNA Database (NFDD). 

“The knowledge I gained from my current research at the UFS has enabled me to make valuable contributions to the board and its recommendations to the Minister of Police,” says Dr Ehlers. 

In her first term as member of the Board – following regular tracking and analysis of reports, the Board noted an increase in the number of outstanding forensic investigative leads – (hits on the National Forensic DNA Database) that were not followed up.

“After we made enquiries, it was determined that the provincial task teams that were to follow up on the leads, were ad hoc structures that lacked the necessary resources. The Board addressed this shortfall by engaging with various stakeholders and helping to establish permanent structures, called Forensic Investigative Units, with dedicated resources – both human and material – to effectively follow up on all forensic DNA investigative leads. The finalised Regulations were published for comment in the Government Gazette on 27 March 2020,” says Dr Ehlers.

Lowering SA crime rate
While serving on this board, she is ensuring that South Africa has a functioning DNA database that contributes to lowering the crime rate in the country. “As a member of the board, I hope to add value to its functioning. I feel that in the future, science will play an even bigger role in crime prevention, detection, and the solving of crimes,” she states.

Dr Ehlers is Programme Director of the Forensic Sciences Programme in the Department of Genetics. She teaches the Crime Scene Management module to second-year students and supervises seven honours, five MSc, and three PhD students. 

Besides her appointment as member of the NFOEB, she values the work she is doing with her students. “The highlight of my career was when my first group of BScHons students in Forensic Genetics graduated and were shortly thereafter appointed by the Forensic Sciences Laboratory as DNA analysts,” she says.

Extending new discoveries in the deep subsurface – UFS paper published in Nature Communications
2015-11-30



Scanning electron microscopy of some of the Eukarya recovered from two different mines. (a) Dochmiotrema sp. (Plathyelminthes), (b) A. hemprichi (Annelida), (c) Mylonchulus brachyurus (Nematoda), (d) Amphiascoides (Arthropoda). Scale bar, 50 µm (a,b), 100 µm (c), 20 µm (d).

Following the discovery of the first Eukarya in the deep subsurface (Nature, 2010) by a research group from the Department of Microbial, Biochemical, and Food Biotechnology at the University of the Free State (UFS) and their international collaborators, intense interest has developed in understanding the diversity of more complex organisms living in these extreme environments.

Prof Gaetan Borgonie from Extreme Life Isyensya, together with a group of UFS researchers, took this research further, resulting in a paper on this research released in Nature Communications – impact factor 11.47.  This paper is an extension of the first reports of more complex life at great depths, and their abilities to survive these harsh conditions.

Ten authors from the UFS contributed with the array of expertise needed to define this discovery. The group was supported by staff from the different mining groups, long-term leading collaborators from the USA and Canada, and the idea specialist driver of the paper, Prof Borganie.

“After a sampling campaign that lasted more than two years, we identified that Platyhelminthes, Rotifera, Annelida and Arthropoda are thriving at 1.4 km depths in fissure water up to 12,000-years old in the South African mines of Driefontein and Kopanang,” said Prof Borgonie, who was appointed as associated researcher in the Department of Microbial, Biochemical, and Food Biotechnology.

This paper really opens a “can of worms” so to speak. According to Prof Esta van Heerden from the Department of Microbial, Biochemical and Food Biotechnology at the UFS they extended to define protozoa and fungi. “However, they are present in low numbers,” she said.

Characterisation of the different species reveals that many are opportunistic organisms. In house-adapted video equipment was used to film inside the fissure for the home of the organisms.

This is the first-known study to demonstrate the in situ distribution of biofilms on fissure rock faces using video documentation. Calculations suggest that food, not dissolved oxygen, is the limiting factor for population growth. The discovery of a group of complex multicellular organisms in the underground has important implications for the search for life on other planets in our solar system.
