UFSAfricaWeek Make this Africa Day a day of reflection - Dr Stephanie Cawood

On 25 May 2018, we celebrate the 55th Africa Day since the Organisation of African Unity (OAU) was formed on this day in 1963. The conception of Africa Day, however, goes back to 1958 to the First Conference of Independent African States held in Accra, Ghana, hosted by Kwame Nkrumah. It was at that conference where Africa Freedom Day was first proclaimed and celebrated on 15 April to commemorate the progress of the African liberation movement as more and more African states gained independence. When more than 30 heads of state of independent African countries met in Addis Ababa, Ethiopia, to form the OAU (now the African Union) on 25 May 1963, African Freedom Day was dubbed African Liberation Day and moved to May. Today, known as Africa Day, it is commemorated across the African continent and the diaspora. 

What is the significance of Africa Day more than 50 years after its inception? African countries may have been liberated, but freedom is often qualified and limited by poverty persistent conflict, poor governance, neopatrimonialism, intolerance and other social injustices? Seen through a gender lens, one may well ask whether we have anything to celebrate when African women and sexual minorities carry such a heavy burden in daily struggles for survival and bear the brunt of persistent conflict. 

On this Africa Day, let’s rejoice in all the progress made since that very first commemoration. Let’s revel in all the vibrant cultural diversity in Africa and its diaspora, but let’s make this Africa Day a day of remembrance and reflection. As a day of remembrance, Africa Day should remind us of the liberation struggles that came before and it should prompt us to reflect on the struggles that remain in areas like gender equality and LGBTQI rights, poverty and sustainable livelihoods, social and environmental injustice, economic dependency, and conflict and what we can do to help effect change for the better. To quote an African proverb, “Use your tongue to count your teeth” for it is only through deep reflection that one will realise what needs to be done and how one should do it.

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.
