Matie student’s photograph among top ten to expose corruptionhttps://www.sun.ac.za/english/Lists/news/DispForm.aspx?ID=2853Matie student’s photograph among top ten to expose corruptionWiida Fourie-Basson<p style="text-align:justify;">A powerful photograph depicting the lack of access to tap water in Katlehong township on the East rand, is one of ten photographs to be exhibited at the International Anti-Corruption Conference in Malaysia in September.</p><p style="text-align:justify;"><img class="ms-rtePosition-1" alt="B_Tony Maake.jpg" src="/english/PublishingImages/Lists/dualnews/My%20Items%20View/B_Tony%20Maake.jpg" style="margin:5px;" />Matie student Tony Maake, who grew up in Katlehong, took the photo in January 2015. His photograph was selected from 1 500 entries in the "Capture Corruption" international photo competition, organised by <a href="http://www.transparency.org/news/feature/capture_corruption_2015_winners">Transparency International</a> in conjunction with the Thomson Reuters Foundation and the International Anti-Corruption Conference.</p><p style="text-align:justify;"> The aim of the competition was to capture the most powerful images of corruption and its devastating impact on lives around the world,</p><p style="text-align:justify;">Tony, a final year BSc student at Stellenbosch University, describes himself as a passionate photographer and story teller: "I want to tell the uncomfortable and hidden stories caused by corruption. I want to educate the world with a camera in my hand, breaking down barriers and eradicating ignorance."</p><p style="text-align:justify;">About the <a href="http://www.transparency.org/news/feature/photo_competition_18_30_age_group_winners">photograph</a> he entered for the competition, he says that, in South Africa, water remains a luxury: "Even 21 years after the transition to democracy, many still lack access to taps and effective sewage systems. There are only a few operational taps in this neighbourhood, making the collection of water a daunting task for the elderly and exposing children to illnesses."</p><p style="text-align:justify;">Over the past few years, there have been frequent media reports about the lack of access to clean water in Katlehong. In certain areas, over 500 households had to share only one tap. </p><p style="text-align:justify;">This gifted student, who does not even own his own camera, says he only started taking photographs in 2012 when he used a friend's digital camera to take pictures of the group while on an exchange programme in Tübingen, Germany.</p><p style="text-align:justify;">However, it was only while helping an exchange student from The Netherlands to shoot pictures at a community project in South Africa in 2013, that he discovered the power of a professional camera and different lenses.</p><p style="text-align:justify;">He is now trying to raise funds to exhibit at a photography school in Munich, Germany, in December. He has also combined forces with the Namibian fashion designer Lourens Loux Gebhardt, better known <a href="http://louxthevintageguru.tumblr.com/">as Loux the Vintage Guru</a>, and <a href="https://www.facebook.com/events/376586089206891/">1042</a>, a platform created for Stellenbosch students to express themselves through fashion.</p><p style="text-align:justify;">Tony has been invited to be the designated photographer to portray Loux's unique African vintage style at <a href="http://www.pittimmagine.com/en/corporate/fairs/uomo.html">Pitti Oumo</a> in Italy, regarded as the world's most important platform for men's clothing and accessory collections.</p><p style="text-align:justify;">In between Tony has also established the <a href="https://www.facebook.com/TonysHouz">Tonys Houz Childrens Foundation</a>, to support children living in extremely poor conditions. On campus, his popular <a href="https://www.youtube.com/watch?v=zvEGn4WAQ7A">BBM dinners</a> (Bigger Better Movement) bring students from different races and cultures together. The only entry requirement is often only a cultural dish and a bottle of wine.</p><p style="text-align:justify;">"I am the first in my family to go to university. When I came to Stellenbosch in 2011, there were many challenges. But it is up to you how you handle it.</p><p style="text-align:justify;">"I want to bring people from different races, cultures and countries together, not separate them further," he concludes.</p><p><strong> </strong></p><p style="text-align:justify;">Links to other exhibitions and photographs:</p><p style="text-align:justify;"><strong>Swedish Interpretation competition (finalists):</strong></p><p style="text-align:justify;"><a href="https://www.facebook.com/SwedeninSA/photos/a.498178783582358.1073741825.465836776816559/901876949879204/?type=1&theater">https://www.facebook.com/SwedeninSA/photos/a.498178783582358.1073741825.465836776816559/901876949879204/?type=1&theater</a></p><p style="text-align:justify;">and</p><p style="text-align:justify;"><a href="https://www.facebook.com/SwedeninSA/photos/a.498178783582358.1073741825.465836776816559/901875743212658/?type=1&theater">https://www.facebook.com/SwedeninSA/photos/a.498178783582358.1073741825.465836776816559/901875743212658/?type=1&theater</a></p><p style="text-align:justify;"><strong>Art and Photography exhibition</strong></p><p style="text-align:justify;"><a href="https://www.youtube.com/watch?v=39vRK9UnnN0">https://www.youtube.com/watch?v=39vRK9UnnN0</a></p><p style="text-align:justify;"><strong>Untold stories exhibition:</strong></p><p style="text-align:justify;"><a href="https://www.youtube.com/watch?v=R5oDeGE7Rk0">https://www.youtube.com/watch?v=R5oDeGE7Rk0</a> </p><p style="text-align:justify;"><strong>BBM Dinner</strong></p><p style="text-align:justify;"><a href="https://www.youtube.com/watch?v=zvEGn4WAQ7A">https://www.youtube.com/watch?v=zvEGn4WAQ7A</a></p><p style="text-align:justify;"><strong>Russel Botmans outing-Mzolis</strong></p><p style="text-align:justify;"><a href="https://www.youtube.com/watch?v=wKaIKxOoDYI">https://www.youtube.com/watch?v=wKaIKxOoDYI</a></p><p style="text-align:justify;"><strong>Past event of Tonys houz & 1042:</strong></p><p style="text-align:justify;"><strong>Tonys Houz 1042 Wine tasting & Vintage Fashion:</strong></p><p style="text-align:justify;"><a href="https://www.facebook.com/media/set/?set=a.322758351204445.1073741909.114059595407656&type=3">https://www.facebook.com/media/set/?set=a.322758351204445.1073741909.114059595407656&type=3</a></p><p style="text-align:justify;"><strong>Tonys houz 1042 Street Fashion-Expo: </strong></p><p style="text-align:justify;"><a href="https://www.facebook.com/media/set/?set=a.364494363697510.1073741913.114059595407656&type=3">https://www.facebook.com/media/set/?set=a.364494363697510.1073741913.114059595407656&type=3</a></p><p style="text-align:justify;"><strong>Social Media</strong></p><p style="text-align:justify;">Facebook: <a href="https://www.facebook.com/TonysHouz">https://www.facebook.com/TonysHouz</a></p><p style="text-align:justify;">Twitter: <a href="https://twitter.com/tonyshouz">https://twitter.com/tonyshouz</a></p><p>Instagram: <a href="https://instagram.com/tonyshouz/">https://instagram.com/tonyshouz/</a></p><p><br></p><p><em>Photo courtesy of Tonys Houz</em></p><p style="text-align:center;"><em class="ms-rteFontSize-1">Media release issued by Wiida Fourie-Basson, media: Faculty of Science, Stellenbosch University, science@sun.ac.za, 021 808 2684</em><br></p>
A major boost for HIV testing in Cape Townhttps://www.sun.ac.za/english/Lists/news/DispForm.aspx?ID=2963A major boost for HIV testing in Cape TownKim Cloete<p>A campaign to encourage more people to test for HIV led to hundreds of commuters and taxi drivers flocking to a mobile clinic, which consisted of eight tents, and was set up on the deck of Cape Town’s central train station.</p><p> Teams of counsellors and nurses offered HIV counselling and testing, screening for TB and diabetes as well as blood pressure checks and advised on family planning. They distributed condoms and asked about possible symptoms of Sexually Transmitted Infections (STIs) during the three-week stint on the busy station deck.</p><p>“The tents were never empty. There were always people getting tested. It was very exciting. We were helping by giving people the power to keep themselves healthy, and if HIV positive, to get medical attention,” said Leandie September, Target 5000 Coordinator for the Desmond Tutu TB Centre (DTTC) in the Faculty of Medicine and Health Sciences at Stellenbosch University.</p><p> The tents were set up as part of the Target 5000 Campaign, funded by the President’s Emergency Plan for AIDS Relief (PEPFAR) through the US-based Centre for Disease Control and Prevention (CDC). The target was to get an extra 5,000 people in Cape Town tested for HIV within three months.</p><p> The DTTC took up the challenge. With the help of the City of Cape Town Health Directorate, they were able to set up a mobile operation, brought in a caravan, eight tents and teams of counsellors, nurses, data clerks as well as mobilisers who spread the word about the service.</p><p> During the day, two people with loudhailers walked up and down the crowded station deck, taxi rank and shops, encouraging people to test, while others handed out pamphlets and directed people to the tents. </p><p> Petronella Njiva, who runs a small hairdressing salon on the station deck, said it was a very convenient service.  </p><p>“I work seven days a week, so this is good for me. I can go and test for free right here and then get back to work. It only takes fifteen minutes to get my results from the HIV test.”</p><p>The response exceeded the expectations of the DTTC. </p><p>“It was fantastic. People were getting tested who wouldn’t typically go to a clinic for an HIV test. Over half of the people who came to get tested were men. Many young people and people who are not aware of any signs or symptoms of disease were popping in. We provided early case detection and linkage to HIV care,” said Sue-Ann Meehan, who heads up the Community HIV Prevention Programme (COMAPP) for the DTTC.</p><p> Taxi driver, Sindiso Busakwa, liked the convenience as well, and said many drivers did not have time to queue at a clinic to get tested for HIV.</p><p>“This is so much easier than going to the clinic, because the service is coming to us. We don't always have a good reputation as taxi drivers. We want to change that. We want to set a good example by testing for HIV and encouraging others to do the same.”</p><p>Despite a drop in new HIV infections in South Africa, many people are still falling through the cracks, and haven’t been tested or been treated for HIV.</p><p>“We need to halt the HIV epidemic in South Africa by increasing access to HIV testing, finding people who are HIV infected and linking them to care at public health clinics so that they can get treated,” said Meehan.</p><p> Findings indicated that about six percent of people who accessed the mobile clinics at the Cape Town station were HIV positive. This is compared to about four percent in the communities where COMAPP usually works.</p><p> In addition to Target 5000, COMAPP sets up its caravans and tents on a smaller scale every day in five communities throughout Cape Town, taking its services to shopping centres, taxi ranks and other busy areas. </p><p> The Target 5000 campaign moved to the busy Bellville and Du Noon taxi ranks, as well as the Wallacedene community near Kraaifontein in late July and August.</p><p> The campaign is also working towards the 90-90-90 targets set by UNAIDS.</p><p> UNAIDS has set targets that 90% of all people living with HIV will know their HIV status by 2020, with 90% of people with diagnosed HIV infections receiving sustained antiretroviral therapy. It’s third goal is for 90% of people who receive antiretroviral treatment to have viral suppression.</p><p>Photo: Vuviseka Pefile and Nosipho Dlangalavu, both counsellors from the Desmond Tutu TB Centre at Stellenbosch University, in the tent where they have been testing and counselling people about HIV.<br></p>

IPB’s winning science team a boost to technical terminologyhttps://www.sun.ac.za/english/Lists/news/DispForm.aspx?ID=5321IPB’s winning science team a boost to technical terminologyB Loedolff<p style="text-align:justify;">Two MSc students from the Institute for Plant Biotechnology (IPB) of the Department of Genetics at Stellenbosch University (SU), Melt Hugo and Janto Pieters (under the guidance of their supervisors, Drs Shaun Peters and Bianke Loedolff), proved this year that science knows no bounds where language is concerned. Messrs Hugo and Pieters attended the annual Student Symposium in Science 2017 at the University of Pretoria (UP), where all the work had to be presented in Afrikaans – no mean feat. Especially for Mr Hugo, a second-language speaker of Afrikaans, who presented his work on exotic sugars (the raffinose family of oligosaccharides) in poster format, following this up with a talk of four minutes on the topic. Mr Hugo triumphantly returned with two prizes: The AfriForum prize for an exceptional contribution by a non-mother-tongue speaker of Afrikaans and the Ctext award for a contribution with merit for his poster. Mr Pieters was selected to talk on his work on metagenomic libraries and the search for biopolymer-forming sugars that can serve as prebiotic substances. Mr Pieters, who could practise his talk (supplemented by an iron, ironing board and TV) only the evening before the conference, walked away equally triumphantly with a science merit prize, the Blue Stallion award (Sigma Plot), for his contribution. As if this were not enough, both participants' presentations are to be published in the South African Journal of Science and Technology in expanded and in a poster summary format.</p><p style="text-align:justify;">Messrs Hugo and Pieters challenged not only their own limits of language in science but also proved that you can represent science on any platform. The two are looking forward to obtaining their MSc degrees in December 2018, after which they plan to tackle the PhD road in science. May we see more of the pioneering work of these two versatile SU students in the future.</p><p style="text-align:center;"> </p><p style="text-align:justify;">Photo: MSc students and their supervisors at the science poster presented by Mr Melt Hugo at the Student Symposium in Science 2017 at UP.

Using local entomopathogens to control the Mediterranean fruit fly https://www.sun.ac.za/english/Lists/news/DispForm.aspx?ID=5372Using local entomopathogens to control the Mediterranean fruit fly Monique James<p>​</p><p style="text-align:justify;">A recent study conducted by Stellenbosch University, aimed to contribute to the knowledge on biological control agents, such as entomopathogenic nematodes (EPNs) and entomopathogenic fungi (EPF), present in South Africa, which could be used against the Mediterranean fruit fly and be incorporated into current management practices.</p><p style="text-align:justify;">The Mediterranean fruit fly, or Medfly, <em>Ceratitis capitata </em>(Wiedemann), is a notorious pest which originates from sub-Saharan Africa, but has also invaded and established throughout many tropical and warm temperate regions of the world. It is a common pest in many parts of South Africa and is the dominant fruit fly species in the Western Cape Province. Medflies utilise fruits as host for their offspring, which feed and develop in the fruit eventually exiting as third instar larvae to pupate in the soil. This life cycle results in the Medfly causing extensive crop damage and loss, requiring expensive controls and post-harvest treatments and has also resulted in restrictions to the export market. Current control methods mainly aim at controlling the adult life stage, but generally involve harmful chemicals which are hazardous to the environment and peoples' health. More environmentally-friendly, sustainable and efficient alternatives are thus required for use against this pest in an Integrated Pest Management (IPM) strategy.</p><p style="text-align:justify;">Entomopathogens are organisms which are pathogenic to insects and EPNs and EPF both make use of suitable insect hosts to feed and breed. The free-living life stages of EPNs are known as infective juveniles, or IJs, and these organisms carry symbiotic bacteria in their gut, which is crucial for killing their host. EPF spores are abundant in the soil, and although non-mobile, are able to penetrate the skin of a suitable host when they come into contact, eventually killing the host. The soil life stages of the Medfly (third instar larvae, pupae and emerging adults) could thus be targeted by EPNs and EPF and utilization of these natural enemies could offer a biological Medfly control method.  </p><p style="text-align:justify;"> </p><p style="text-align:justify;">In order to find local EPN and EPF species, soil was sampled from different fruit orchards in known fruit fly problem areas. Entomopathogens were isolated from the soil by adding highly susceptible wax moth larvae and meal worms, as well as Medfly larvae, to each soil container as bait. Baiting with the target host was done to try and directly isolate Medfly-specific EPNs or EPF that may have been present in the soil. Species were later identified using morphological and molecular tools.</p><p style="text-align:justify;">In order to identify possible control agents, the ability of different entomopathogenic isolates to infect and kill Medfly was tested.  Five different local EPNs (<em>Heterorhabditis zealandica, H. noenieputensis, H. bacteriophora, H. indica, Steinernema yirgalemense</em>) were tested in the laboratory by exposing individual third instar larvae to 50 and 100 IJs in a confined well and assessing infectivity and death after two weeks. Soil collected EPF (<em>Metarhizium robertsii </em>and <em>Beauveria bassiana</em>) and commercial EPF products (EcoBb®, Broadband® and Meta69) were similarly tested by dipping larvae into the fungal suspension (concentration = 1 x 10<sup>7</sup> conidia/ml) and then confining each larva to a well. After two weeks, any dead insects were placed on nutrient agar plates to facilitate fungal growth in order to confirm if the death was caused by a fungal infection (mycosis). Pathogenicity of selected entomopathogens were further tested in a more natural environment by adding third instar larvae to containers containing sterile soil inoculated with the EPNs or EPF.</p><p style="text-align:justify;"> </p><p style="text-align:justify;">All EPN species tested were able to infect and kill the exposed Medfly larvae. In the soil bioassays, the native EPN, <em>H. noenieputensis, </em>caused >92% mortality. Most exposed larvae died as pupae, showing that <em>H. noenieputensis </em>was able to find and infect the final instar larvae soon after they entered the soil, thus preventing them from emerging as adults. Another species, <em>S. yirgalemense, </em>which is currently in the process of being formulated into a commercial product, caused mortality of 34-53%. Its ability to offer some control against Medfly as well as other important pests such as false codling moth and codling moth, is likely to enhance the acceptance and uptake of the commercialised product by growers.</p><p style="text-align:justify;"> </p><p style="text-align:justify;">Both the commercial EPF products and soil isolates were able to infect and kill Medfly. The pathogenicity of the commercially available EPF products against Medfly observed should provide encouragement for the increased use of such alternatives for the control of agricultural pests, including the Medfly. This study found that the local soil-sampled <em>Metarhizium robertsii </em>strain MJ06, which was isolated using a Medfly larva, was able to provide a high level of control of both pupae and adults. When larvae were exposed to sand inoculated with the two non-commercial isolates, high adult mycosis was caused. Mycosis of adults showed that soil treatments can assist in fruit fly control, but also highlights the potential of using these two non-commercial isolates for control of the adults. They could be tested for use in bait sprays, or autoinoculation traps where adults are attracted, infected and killed by the EPF. </p><p style="text-align:justify;"> </p><p style="text-align:justify;">In conclusion, the ability of entomopathogenic nematodes and fungi to naturally infect and kill soil-dwelling stages of Medfly makes them useful natural enemies. The integration of such EPNs and EPF individually, and possibly together, into an IPM system could ultimately provide sustainable and effective control of this target pest and future research efforts should focus on the candidates highlighted in this study. This research has thus provided necessary groundwork and information on potential biological control agents for the control of Mediterranean fruit fly in South Africa. </p><p style="text-align:justify;">The study was presented as an MSc thesis of the student, Monique James, carried out at the Department of Conservation Ecology and Entomology of the Stellenbosch University. The study and was supervised by Prof. Antoinette P. Malan, Dr Pia Addison and Dr Minette Karsten. HortGro and the National Research Foundation provided funding (NRF reference: SFH150706123538).</p>
Young scientists rewardedhttps://www.sun.ac.za/english/Lists/news/DispForm.aspx?ID=1754Young scientists rewardedMedia: Fakulteit Natuurwetenskappe<p>The <a href="http://academic.sun.ac.za/cib">Centre for Invasion Biology</a>'s (C•I•B) book prize for the best junior research project in the environmental sciences this year was awarded to Charl-Henri Schoeman and Henko van Wyk, grade 9 learners from Curro Private School in Langebaan.</p><p>This award was made during the Stellenbosch regionals for the <a href="http://www.exposcience.co.za/index.php/about-us.html">Eskom Expo for Young Scientists</a> which took place on Friday (22 August 2014) in Stellenbosch. The C•I•B is a DST-NRF Centre of Excellence, hosted at Stellenbosch University (SU).</p><p>Charl-Henri and Henko's project, titled "Red is not always nice", also received the award for the best junior research project addressing environmental issues. This award was sponsored by the SU Faculty of Science.</p><p>Ms Dorette du Plessis, programme manager of the Iimbovane Project at the CIB and one of the judges, said the two learners identified a real problem in their immediate environment, namely red ferrous oxide in waste water, and came up with a potential practically solution. They developed a chemical process which causes the ferrous oxice to coagulate after which it can be filtered out of the water. The water can then be reused.</p><p>The Stellenbosch regionals for the Eskom Expo for Young Scientists are organised every year by volunteers from SU's <a href="http://www.suncep.sun.ac.za/">Centre for Pedagogy</a> and the <a href="/english/faculty/science/Pages/default.aspx">Faculty of Science</a>. This year more than 170 learners from 15 different schools entered 129 projects for the regionals. Several of SU's scientists volunteered as judges.</p><p>The Faculty of Science also sponsored ten category prizes of R350 each and provides support of R1000 towards the flight costs of each of the regional winners to enable them to participate in the national Eskom Expo International Science Fair (ISF 2014) taking place in Johannesburg during the October school holidays.</p><p>Mr Parthy Chetty, executive director of the Eskom Expo, says an interest and love for science is not only personally fulfilling, but is fast becoming a prerequisite for survival in the new knowledge economy.</p><p>"The Eskom Expo provides a firm foundation from where learners' passion for science can be developed further. We need young scientists to help our country become technologically more competitive," he wrote in the foreword to the programme.</p><p>Schools and learners who would like to participate in next year's regional expo, should contact Erika Hoffman at 021 808-3482 or <a href="mailto:ehoff@sun.ac.za">ehoff@sun.ac.za</a></p>
