Global genealogy explored at UFS guest lecture
Karen Ehlers, lecturer in Department of Genetics; Prof Eugenia D’Amato, guest lecturer and Associate Professor: Department of Biotechnology at the UWC, and Prof Paul Grobler Head of Department: Genetics at the UFS.

Prof Eugenia D’Amato held a lecture at the University of the Free State (UFS) Department of Genetics about the research activities she has conducted in her unit at the University of the Western Cape (UWC), in the Forensic DNA lab of the Faculty of Natural Sciences.
 
The lecture focused on research topics she has piloted, including the use of forensic markers in South Africa. Prof D’Amato also spoke on food forensics, the identification of anti-apartheid activists, understanding human genetic variation, and the implementation of novel/refined methods, with a strong emphasis on the forensic use of Y chromosome-based information.

She concluded her PhD studies at the University of Buenos Aires in Argentina, at the forensic lab. Currently, Prof D’Amato participates in numerous genotyping international forensic collaborations.

 “A survey of existing genetic diversity,
the distribution of diversity, the forensic
parameters and applications are a few of
the subject matters which are important
components of the GlobalFiler project.”
Prof Eugenia D’Amato

She also belongs to the working committee of the “Innocence Project South Africa”.

Her training and subsequent experience in population genetics facilitated the design of a Y chromosome “kit”, as well as the analysis and successful identification of various individuals from highly degraded DNA. Her lecture revealed interesting statistics about how poorly represented African diversity is in the existing world population databases. She explained that mechanisms that drive differentiation include random “genetic drift” and historic demographic processes.
 
Prof D’Amato indicated that her “Database Projection” project for 2018/2019 aims at profiling the population groups of South Africa, Lesotho, and Zimbabwe. She further explained that a powerful tool for forensic application has been developed, and that there is potential for other applications including haplogroup prediction and the study of demographic history, that will aid her projects in the future.

Little ‘Devil’s Worm’ on Top 10 New Species list

A minuscule little worm found and researched with the assistance of researchers at the university has made it onto the list of Top 10 New Species of the world. The list was published by the International Institute for Species Exploration (IISE) at Arizona State University and a committee of scientists from around the world. It lists the top ten new species described in 2011.

An article on the new worm species appeared in the authoritative journal Nature in June 2011.
 
Prof. Esta van Heerden, leader of the university’s research team, says, “In our wildest dreams, we could not have imagined that we would get so much reaction from the worm’s discovery. We had to do so many checks and balances to convince Nature that the worm could survive in the old and warm water. We were very excited when the article was accepted but the media reaction was unbelievable.”
 
The tiny nematode, Halicephalobus mephisto (Devil’s Worm) of about 0,5 mm in length, is the deepest-living terrestrial multi-cellular organism on earth. It was discovered in the Beatrix gold mine near Welkom at a depth of 1,3 km.
 
The IISE says in a statement the species is remarkable for surviving immense underground pressure as well as high temperatures. The borehole water where this species lives has not been in contact with the earth’s atmosphere for the last 4 000 to 6 000 years.  
 
This top-10 list includes a sneezing monkey; a beautiful, but venomous jellyfish; a fungus named after a popular TV cartoon character; a night-blooming orchid; an ancient walking cactus creature; and a tiny wasp. A vibrant poppy, a giant millipede and a blue tarantula also made it onto the list.
 
The international selection committee made its choice from more than 200 nominations. They looked for species that captured the attention because they were unusual or because they had bizarre traits. Some of the new species have interesting names.
 
Prof. Van Heerden says, “We are very thankful for the exposure that the university gets as a result of the inclusion on the list and we enjoy the international cooperation immensely.”
