Mfumo wa Gazankulu
Mfumo wa Gazankulu (1971 – 1994) ikhale ka mfumo wa tiko-xikaya e Afrika Dzonga, lowu simekiweke hi mfumo wa xihlawu-hlawu hi xikongomelo xo rhangela tiko xikaya ra vatsonga. Mfumo lowu a wu andlala ndzhawu ya khale ka n'walungu wa Transvaal (leyi namunthla nga xifundzha xa Limpopo) na vuxa bya Transvaal (leyi namunthla kunga xifundzha xa Mpumalanga).
Matimu[Lulamisa | edit source]
Gazankulu yi nyikiwe vutilawuri kusuka eka mfumo wa tiko hi lembe ra 1969, naswona ntsindza wa mfumo awuri e Giyani. Tiko xi kaya ra Gazankulu a ri sungula e xibhedlele xa Elim, e kusuhi na Makhado, kusuka kona ri kongoma e vuxa dyambu ri kongoma nambu wa Levubu, miti ya Valdezia na Bungeni hi yona miti leyi kulu ya matsonga endzhaweni leyi, naswona yina kwalomu ka 50 000 wa va aka tiko, hi kuya hi ntsengo wa nhlayo ya vanhu ya 2015. Tiko xi kaya leri ri thlela ri ndlandlamuka riya fika e ribuweni ra nambu wa Ritavi e kusuhi na Skukuza e Hazyview (Mpumalanga). Ku anama ka tiko xikaya leri, kusuka e Elim kuya e Hazyview, akuri kwalomu ka 317 wa tikhilomitara.[1] Tiko xikaya leri a ri vumbiwa hi Elim, Giyani na Malamulele, kuhlanganisa na swiyenge swinharhu leswikulu swa Bushbuckridge, Tzaneen na Phalaborwa.
Emahlweni ka nawu wa tiko wa lembe ra 1913, Bushbuckridge, Phalaborwa na Tzaneen a ku ngari matiko ya matsonga, matiko lawa ma hlanganisiwe na Elim, Giyani na Malamulele ku tumbuluxa tiko ra vatsonga. Nawu lowu wa lembe ra 1913 wu vangile swiphemu swinharhu swa matiko ya matsonga leswi a swiri handle na le kule ka xiphemu lexikulu. Hi malembe ya va 1960, Nkulukumba H.W.E Ntsanwisi u hluriwile ku sivela mfumo wa tiko ku endla mindzilakano handle ko vulavurisana na va aka tiko. Gazankulu a yi akelane na matiko xikaya man'wana ya vantima, kunga Venda, Lebowa na Kangwane. Matiko xikaya lawa na swona ma xaniseke ngopfu hikwalaho ka ku tekeriwa tiko na ku beriwa mi ndzilakano leyi nga tsisisekiku hi mfumo wa Afrika Dzonga.

Xikalo xa vuxokoxoko na ku ba ka mbilu eka tluka leri xi ta pfuna ku hlamula xivutiso lexi naswona xi ta ku pfuna ku hatlisa u kambela ku ba ka mbilu ya wena na ku pima ku ba ka mbilu ya wena.
I nhlayo ya minkarhi leyi mbilu ya wena yi baka ha yona hi minete loko u nga si nghenela ntirho wihi na wihi ku ringana nkarhi wo karhi. I mpimo wa mbilu ya wena loko u hlaya, u tshame esofeni u hlalela thelevhixini kumbe u dya swakudya.
Ku ba ka mbilu loko u wisa ku hambana ni ku ba ka mbilu ya wena loko u ri karhi u endla ntirho kumbe u endla vutiolori. I swa nkoka leswaku u nga pfilunganyi mimpimo leyimbirhi.
Hi ntolovelo u ta boheka ku hlayela ku ba ka mbilu ya wena ku ringana minete hinkwayo, kumbe ku ringana 30 wa tisekoni ivi u andzisa hi 2, kumbe 15 wa tisekoni ivi u andzisa hi 4, etc. Xibalo xa ku ba ka mbilu eka tluka leri xi ta ku endlela swibalo ivi xi ku nyika ku ba ka mbilu ya wena hi xiringaniso hi tisekoni ti nga ri tingani ntsena.
Pima ku ba ka mbilu ya wena endzhaku ka loko u nga tirhi nkarhi wo leha swinene. 15-30 wa timinete tifanele kuva tiringanerile.
Tindhawu to tala leti rhendzeleke miri laha ku khulukaka ngati ku vonakaka kona ti nga tirha tanihi tindhawu to kambela ku ba ka mbilu ya wena. Hi ntolovelo u nga twa ku ba ka mbilu ka wena hi ku olova hi rintiho ra wena etlhelo ra xikunwana xa voko ra wena. U nga ha tlhela u veka tintiho ta 2 etlhelo ka nhamu ya wena, ekusuhi na windpipe ya wena.
A hi vanhu hinkwavo lava nga ni mbilu leyi fanaka. Ku ba ka mbilu ka hambana hi ku ya hi vanhu. Ku landzelela ku ba ka mbilu ya wena swi nga ku nyika rungula ra nkoka malunghana ni rihanyo ra mbilu ya wena, naswona xa nkoka swinene, ku cinca eka rihanyo ra mbilu ya wena.
Leswi tekiwaka tanihi ku ba ka mbilu loku hanyeke kahle kumbe loku nga riki na rihanyo loko u wisa swi katsa swilo swo hlayanyana, ngopfu-ngopfu, loko u ri wa xinuna kumbe wa xisati, ni malembe ya wena. Xifaniso lexi nga eka tluka leri xi ta ku pfumelela ku hlawula rimbewu ra wena na malembe ya wena ku ku komba spectrum ya swiyenge swa ku ba ka mbilu eka wena.
Hi leswi swilo leswi heleleke swinene leswi nga khumbaka ku ba ka mbilu ya wena:
Ku ba ka mbilu loku "tolovelekeke" ka ku wisa eka vanhu lavakulu ku le xikarhi ka 60 na 100 wa ku ba hi minete (BPM).
Hi ntolovelo, loko mbilu ya wena loko u wisa yi ri ehansi, mbilu ya wena yi tirha kahle naswona i xikombiso xa ku ringanela ka wena.
Hi xikombiso, mutsutsumi wa mpfhuka wo leha a nga ha va ni ku ba ka mbilu loko a wisa kwalomu ka 40 wa ku ba hi minete.
Ku ba ka mbilu loku "tolovelekeke" loko u wisa a hi xikombiso xa nsusumeto wa ngati lowu "tolovelekeke". Nsusumeto wa wena wa ngati wu fanele wu pimiwa hi ku hambana ni hi ku kongoma.
Sayiti leyi yi endleriwe ku pfuna munhu la tolovelekeke loyi a tsakelaka ku ba ka mbilu ya yena hi ku olova. A yi endleriwanga tanihi xitirho xo kambela vuvabyi bya vutshunguri. A hi xitirhisiwa xa vutshunguri lexi kambisisiweke hi tintangha ta xiphurofexinali. A yi endleriwanga ku siva madokodela ya swa vutshunguri kumbe ku burisana na vatirhi lava tiyisisiweke. Loko u ri na swivilelo swa vutshunguri, xiphiqo xa swa vutshunguri, u titwa u vabya, u ri na timhaka tin’wana ta vutshunguri, hi kombela u vulavurisana na mutivi wa swa vutshunguri loyi a nga na layisense.

Vatsonga
Vatsonga i rixaka ra vanhu swivongo swo hambana-hambana lava va kumekaka etikweni ra Afrika. Vatsonga va kumeka ngopfu e Afrika Dzonga, hi laha rixaka ra Vatsonga ri nga hetelela ri tshama hi ku rhula tani hi rixaka leri ri tivekaka ri ri Vatsonga. Vatsonga i vanhu lava va vulavulaka ririmi ra Xitsonga. Mutsonga namuntlha wa swi kota ku langha ku dyondza Xitsonga exikolweni; ririmi ra manana ra yelana hambi kuri exikolweni kumbe mavulavulelo ya le kaya, kambe van'wani va tsakela ku antswisa vutivi hi ndlela ya vudyondzisi bya matimu ya Xitsonga ni ku ti antswisela hi ririmi ro hlantsweka.
Ku Hluka ka Rixaka[Lulamisa | edit source]
Vatsonga lava va nga tala hi xidzi i Vatonga (Thonga), Varhonga (Ronga) na Vatswa (Tswa) lava a va vulavula ririmi leri ri tivekaka tani hi Xitonga, Xirhonga, na Xitswa. Vatsonga vo sungula ku ta tiveka hi vito ra Vatsonga kumbe Vatonga va fikile laha e vuxa bya tiko-nkulu ra Africa e tindzhawini to fana na vo Zambia, Malawi, Zimbabwe, na Mozambique kwalano ka vo 500AD. Ku yela hi vo 1200 Vatonga na Vacopi se a va fume tiko ra le Vudzonga bya Mozambique va hlota tindlopfu va xavisa timhondzo na switirhisiwa swa risinda.[2] Va akile kona e Nyembani na le Xai-Xai, laha va nga tekana na Vatswa, Valozyi, Valambya, na Vashona, kutani va fuma rixaka ra Vatsonga. Eka vantukulu va vona ku fikile laha nga nga ntumbuluka tinxaka to fana na va Nondwani na Mpfumo ku suka hi vo 1350 lava a va tiveka va ri Varhonga tani hi leswi a va tshama e Vudzonga-vuxa (Vurhonga) na kuva va katsa ririmi ra Xitonga na Xikalanga. Vatsonga va hlanganile na maputukezi hi 1554 e Delagoa Bay, endzhaka loko maputukezi va kongomisa xikepe xa vona e tikweni ra Vatsonga.[3] Perestrelo u tsarile hi minkarhi liya leswaku Vatsonga a va ri kona hi 1554 e tikweni ra le Mozambique laha a kuri na mimfumo swivongo swa va Tonga na va Rhonga.
Henri Junod u tsarile swo tala hi minkarhi ya khale ka rixaka ra Vatsonga ku suka kwalano kavo 1600 ku fika 1900. Hi minkarhi ya xikhale, Vatsonga a va tsakela ku ti tiva tani hi "va Tonga", "Vadzonga", kumbe "va Rhonga", kambe hinkwaswo swi vula rixaka rin'we.[4] Hi vutsalwa bya xi Nguni, "Tonga" yi tsariwa yi ri na "h" tani hi leswi eka ririmi ra Vanguni marito yo sungula hi "T" ya landzela hi "h" - hikoho kwalano Vanguni va ri tsala tani hi "Thonga", loko va vula Tonga. Vito leri ra Tonga i ra khale ngopfu, i ra khale ku tlula mintlawa ya swivoga na tinxaka to tala ta laha eAfrika Dzonga.
Mimfumo Swivongo[Lulamisa | edit source]
Vanhu va rixaka ra Vatsonga va tele ngopfu, nkarhi wun'wana swi tsandza na lava va tsarisaka tinhlayo ta vanhu ku hlayela Vatsonga hi ku helela. Minkarhi yo tala tinhlayo leti ti paluxiwaka i ta Vatsonga va le Afrika Dzonga na le Mozambique ntsena. Eka Vatsonga ku na mimfumo swivongo swo tala, vo tala i vantukulu va Vatonga na Varhonga, van'wani i vantukulu va Vatswa, van'wani i vantukulu va Valozyi, van'wani i vantukulu va Vambayi, van'wani i vantukulu va Valambya.
Exikarhi ka Vatsonga ku na lava va nga nghena e Vutsonga hi 1820, va nga vantukulu va ka Ndwandwe, va ka Soshangane, kambe nkarhi wun'wana va ti hlaya va ri Vanguni se hi koho kwalano nkarhi un'wani swi nga tiveki ku va fanela ku hlayiwa eka rixaka ra Vatsonga kumbe eka rixaka ra Vanguni. Hi ku twisisa ka Vatsonga vo tala, vantukulu va Soshangane hi vona ntsena va nga ti vitanaka vaShangane, Machangana kumbe Amashangane. [5]
Vatsonga va kumeka e tindzhawini to hambana-hambana e Afrika Dzonga. Va kumeka hi xitalo e Limpopo, kambe na le Gauteng, Mpumalanga, na Swaziland va kumeka. Mintlawa ya marhavi ya Vatsonga hi kuya hi matirhiselo ya ririmi ra Xitsonga na vuendli bya mintolovelo ya Xitsonga, ku hlayiwa vanhu lava phatlukaka eka swiyenge leswi landzelaka:
- VaBila - VaDzonga - VaHlanganu - VaHlave - VaHlengwe - VaKhosa - VaLambya - VaLozyi - VaN’wanati - VaNdzawu - VaNkomati - VaNkuna - VaRhonga - VaShangane - VaTembe - VaTswa - VaXika - VaXingwedzi
Swiyenge leswi, mavito ya swona ya huma eka vakokwani wa vona kumbe vito ra mfumo xivongo xa rixaka ra vona, kambe hinkwavo va hlanganisiwa hi ririmi ra Xitsonga na ndhavuko wa Xitsonga, swo fana na mambalelo, vunanga, macinelo, tingoma, na swin'wana.

Vukhongeri
Vukhongeri i nxaxamela wa mindzhavuko ya matikhomele, swi endlo, mavonele, matsalwa yo kwetsima, tindzhawu to kwetsima na mafambisele ya vutomi ya vanhu.[1] vukhongeri byo hambana hambana byi nga katsa ku mbe ku pfumala swiyenge leswi hlanganisaka "Vukwembu",[2] "swilo leswi kwetsimaka",[3] "Ripfumelo",[4] "Xivumbiwa kumbe swivumbiwa swa matimba swa moya"[5] kumbe muxaka wokarhi wa "ku nga heli naswona swi tisa matimba eka vutomi."[6]
Swiendlo swa vukhongeri swinga katsa switoloveto, kuchumayela, switsundzuxo na vugandzeri (bya Xikwembu/Swikwembu), maganzelo, minkhuvo, kuthwasa, mintirho ya rifu, mintorho ya micato, kukhongela, vunanga, kuhlanganisa na mindzhavuko ya vanhu. Vukhongeri byi na matimu yo kwetsima na swiviko. leswi hlayisiweke eka matsalwa yo kwetsima, na swifungo, na tindzhawu, leswi swi ringetaka ku nyika xivangelo xa vutomi. Vukhongeri byi nga thlela byi va na switori swa xikombiso, leswi van'wana va malandza va tshembaka leswaku swa ntiyiso, leswi nga na xikongomelo xo hlamusela masungulo ya vutomi, ntumbuluko na swin'wana. Ripfumelo, ehenla ka swivangelo, rivoniwa tani hi xivangelo xa tidyondzo ta Vukhongeri.[7] Ku na kwalomu ka 10,000 wa tinxaka ta vukhongeri emisaveni hinkwayo.[8] kwalomu ka 84% wa va aki va misava va pfumela eka yin'we ya nthlanu wa vukhongeri, kunga Vukreste, Vusurumani, Vuhindu, Vubhudha na vukhongeri bya ndzhavuko.[9]
Kuya emahlweni ka nhluvuko na sayensi, ku vangele leswaku vukhongeri byi soriwa ngopfu e manguveni lawa, hambileswi vanhu van'wana vanga pfuleki eka vukhongeri.[10] Tidyondzo ta vukhongeri ti hlanganisa, Vufundhisi, tidyondzo ta sayensi ni vukhongeri.

FameLab is an international competition designed to engage and entertain by challenging young scientists to communicate their science to a public audience in under 3 minutes. Talks are fun and engaging, making science relevant to everyone, without using jargon or formal presentations. Talks are judged on content, clarity and charisma.
Mopani, in Limpopo, is a tropical region and the province’s agricultural hub. Because it is a tropical region, it has only two seasons - the dry and wet season - making it highly susceptible to climate change. Letago’s research look at the impact of climate change on small holder farmers and agriculture in this region. Climate change means long term variability in weather patterns and is often characterised by increased temperature and changes in precipitation. In the Mopani district, in the wet seasons there are more floods, thunderstorms and hailstorms, while in the dry seasons, there are more veld fires, droughts and dry spells. The impact of climate change can be seen in agriculture, through reduced crop production and general poor crop health, more animal disease and land degradation. How well farmers perceive and understand climate change determines how well they adapt to it. In the Mopani district, farmers use indigenous knowledge passed on from generation to generation to adapt to climate change more than the methods prescribed by the department of agriculture. Letago’s research advocates for the inclusion for the indigenous knowledge systems as viable sources of knowledge for disaster management strategy in climate change policies.

HIV positive people take medication called ARVs (antiretrovirals) to help them live longer and healthier lives. However, the ARVs also change how mitochondria in our cells of the body work. Mitochondria are found inside cells and they work like batteries. They give energy to cells but when they ‘run down’ they affect organs in the body, including the eyes. Eyes are important for our sight, but also, through them, we can get an overall view of someone’s health and lifestyle. This is because the blood vessels in the eyes are directly visible. You can tell if someone is taking their medication or not. Early diagnoses of different diseases can also be made through the eyes. Lungile’s research will track how ARVs and HIV affect the body by taking a picture of the retina, part of the eye that helps us to see, using optical coherence tomography or OCT for short. The OCT allows you to see the different layers in an eye. These layers in HIV positive people and non-infected people have been found to be different. Lungile’s research will study the differences in the pigment layer. It is a non-invasive method and will allow her to track how the disease is affecting the body.

A healthy skin and pore has an outer most layer (or epidermis), the middle layer (or dermis), and hair follicles. Sebaceous glands produce the body’s natural oil called sebum to help moisturise and protect the skin, and only a small amount of sebum is necessary to maintain soft skin. But with acne, sebum is over produced. This causes the top layer of dead skin cells to become very sticky, which creates an environment for bacteria to overgrow, causing redness, swelling and pus. Squeezing a pimple causes the infection to spread to other arears of the skin where more acne can develop. Shivani’s research focuses on studying naturally-derived rosehip carrier oil in combination with essentials oils for the treatment of acne. The combination of the oils help to sooth the redness and swelling of the skin and also stops the growth of bacteria. The oils penetrate deep into the skin so the skin is not left greasy and they can restore balance to the skin.

Even though water may look crystal clear and different to murky, brown water, it may not be safe to drink and may contain pollutants that cannot be seen with the naked eye. Example of pollutants that can contaminate water are antiviral medicines, such as Nevirapine, which is used in the treatment of HIV and Aids. Drugs like this find their way into our water systems through urine, faecal waste and simply by flushing them down the toilet. Drinking contaminated water may lead to drug resistance in the near future, or cause other health problems. Therefore, it is important for us to be able to detect these drugs in the water. The current techniques use big machines, are expensive and time consuming. However, sensors that use ‘quantum dots’, which are tiny nanomaterials smaller than the eye can see, can improve the sensitivity and detection limit of drugs found in low concentrations. With these sensors to help detect pollutants, we hope water can be purified better, so people have cleaner and safer water to consume.

Our body has an army to fight against diseases in our body. Vaccines prepare our armies, in the form of ‘antibodies’, to fight against agents that cause disease, such as pertussis, hepatitis B, measles, tetanus and other diseases. But how long do the antibodies keep gathering, fighting and winning against diseases? How long is the body protected by the vaccines that we receive? In people who have been exposed to HIV, how long are they protected through the vaccines that we receive against other diseases? Research shows that people exposed to HIV have immune systems that function differently from those of healthy individuals, acting like an army that is late to war, or outnumbered, or even having ‘blind’ soldiers. The answers to these questions are very important; as these answers inform our national vaccination guidelines. We need to ensure that every individual that is vaccinated is protected and that the protection is long-lasting.

Imagine having to wait for a taxi not knowing what time it will arrive. Imagine having to wait in taxi for it to fill up before it will leave. Imagine having to get up 2 hours earlier than the average car driver to get to work on time. This is the reality for minibus tax commuters in South Africa. There is a solution to these challenges, through an app. The app gives information about where the closest taxi is, where the taxi ranks are and how many people are in the taxi. It gives information to commuters on the best way get from point A to point B using taxis. It allows commuters to rate the drivers and hold them accountable, encouraging them to be reliable, accessible and safe. The app has been co-created with many mini-bus taxi industry drivers, owners and mini-bus industry users. This is science for social impact.

Water is one of the most precious recourses and we cannot survive without it. With climate change, water pollution and a growing population, the availability of fresh water is a challenge. A solution is to re-use and purify ‘grey’ water. ‘Grey’ water is domestic, untreated waste water from showers, basins, laundry and dishwashing. It may look dirty, but it is useful. For example, the water can be piped out directly into the garden to water the plants. ‘Grey’ water can be locally treated and re-used. Treatment includes filtering and isolating any particles that may be in the water. Chemicals are added to treat the water, and, lastly, water is treated using micro-organisms. The final product, which is called effluent, can be released in the local rivers or it can be further treated for home usage. However, this treatment needs to be designed to be able to work on a small scale without using advanced, expensive technology. Adopting such measures into our daily lives can save water.

Like money needs protection against theft, an mRNA vaccine needs protection against being digested or degraded by enzymes and chemicals within the human body. An mRNA vaccine needs protection, like an armoured truck protects money when transported. The mRNA looks like a coiled string. In order to protect it, we can place it in a nanoparticle, which acts like an armoured truck that protects money during transport. A nanoparticle is a very small particle, a billion times smaller than a tennis ball. Like an armoured truck has a driver and GPS to get it where it needs to go, the nanoparticle allows us to modify its outer structure by adding on different proteins, which enable the nanoparticles to go a specific area within the human body.

Social connection with others is very vital to healthy brain development. During adolescence, the social brain responsible for processing and interpreting social situations is changing the most. The brain is like a rose bush; the weak branches are pruned away while the remaining are branches strengthened. This fine-tuning of the brain tissues depends on the environment we grow up in. Covid-19 has changed the entire world overnight and the internet is no longer a luxury but a life-line. Socialisation in the digital world could replicate social interaction and still give adolescents access to education, their friends and their ability to develop awareness, empathy, creativity and community. On the other hand, socialisation and cyber behaviours are more complex than offline social interactions. Anonymity has given rise to trolling, ghosting, and cyber-bullying, intending to harm others. As cognitive scientists, we have come up with a number of ways of testing the development of the social brain. In the lab, we run computerised games that mimic offline and digital social interactions and we measure performance in these tasks over time as participants go through their early teens. The pandemic has redefined childhood and social life globally. Are we strengthening the digital branches of the brain or are we weakening the offline social ones?

There are two kinds of cannabis that differ in their chemical contents and their uses. The first one is called marijuana and contains a chemical that is responsible for making one ‘high’. That chemical is tetrahydrocannabinol, also known as THC. The other one is called hemp, which is commonly used for fibre and contains little THC and, therefore, cannot make one ‘high’. Hemp and marijuana cannot be told apart by just looking at them. However, with a simple, fast and relaible method that shows their chemical differences, hemp and marijuana can be told apart. ‘Chromatography’ is a process whereby a mixture of chemicals is separated into its individual chemicals and can be shown as marks on a paper. The method can be used to determine how much of each chemical, such as THC, is present in an unknown cannabis sample. In 2018, the private use of cannabis is permitted in South Africa. However, its public use, growth and distribution still remain illegal and it is monitored by permits. This detection method can be adapted so that police officials could also use it to determine on the spot if any cannabis sample that is being transported corresponds to hemp or to marijuana. This method can also be used by the medicines regulatory body, SAHPRA, to ensure that cannabis products meet the global requirements.

Mosquitoes kill almost a million people every year through the mosquito-borne diseases that they transmit, such as Zika virus, yellow fever, malaria and dengue. There are over 400 million cases of dengue every year globally. Symptoms include high fever, rash, as well as muscle and joint pain. In severe cases, there is severe bleeding and shock, which is life threatening. As far as we know, there is no dengue transmission in South Africa. However, we know that the mosquito species that transmit dengue are present and our environmental conditions favour the transmission of dengue. Dengue has been emerging and re-emerging worldwide. Hence, we believe SA is at risk of Dengue emerging. Currently, there is no specific treatment for dengue. Mosquito control is the only way to limit it spreading, but mosquitoes are becoming resistant to insecticides. We can use weapons like mathematical modelling to defend ourselves. Mathematical modelling creates an imaginary world that resembles real-life conditions. This helps us to understand how mosquitos operate, as well as finding out how the population will grow and helps us to assess how dengue will spread. The results can guide us on how to make decisions in real-life. Using mathematical modelling is cheaper and it allows us to try different possible scenarios without worrying about the financial and resource limitations. These methods helps us to better equipped to fight the war against mosquitos.

Numerous animals have been used in research in disease modelling and drug development. Humans and animals have many genetic similarities, and share a lot of the same major genes that affect drug efficacy and safety. However, animals like rabbits are not humans and, therefore, and the data that is generated from animal models can be difficult to translate to humans. We need human-relevant models. Stem cells may provide solutions. Stem cells are the regenerative cells of the body and they can become any type of cells in the whole body, such as brain, lungs, heart or liver cells. People can donate stem cells and, in the lab, we can create tiny ‘micro livers’ to test how drugs potentially could potential interact with human livers. This could revolutionise how we see drug safety and efficacy research. It can assist in generating better data that that will be more human-relevant and it takes animals out of the lab and out of harm’s way.

Cyclodextrin can be used to treat cancer along with other chemotherapy drugs. It acts like a vacuum sucking up the cholesterol that protects cancer cells from being destroyed in the body. Cholesterol is a substance found within cells and protects them from death while allowing them to grow, move and multiply. However cancer has too much cholesterol within their cell membrane that protects them. Once the cholesterol is removed, the cancer cells are weakened and other chemotherapy drugs can come in and fight against the cancer cells. Cyclodextrin can save millions of lives.

HIV (Human Immunodeficiency Virus) has infected about 37.7 million people worldwide, two thirds of whom are in Sub-Saharan Africa. There is still no cure for it. Once the virus is in the body, it instructs cells to make more copies of itself. The copies then infect healthy cells and spread the infection throughout the body. A person that is infected with HIV takes ARVs, which is now only one pill a day. However, in some cases the virus lies asleep in some of the cells and does not produce copies of itself. It cannot be targeted by the ARVs, and this makes finding a cure for HIV difficult. These cells cluster together to form a ‘HIV latent reservoir’, but it is not known how the reservoirs are formed. HIV has a special gene called ‘tat’ that plays an important role in HIV replication. Changes in ‘tat’ can either decrease or increase HIV replication. ‘Tat’ works together with ‘P-TEFb’ to enhance the rate of HIV replication. Zakhithi’s research aims to find how changes in ‘tat’ affect its ability to work with ‘P-TEFb’ and also to know how to wake up the sleepy virus so it can begin to replicate again and thus be targeted by ARVs. This will edge us closer to finding the cure for HIV.

Caitlin fell in love with the prehistoric world and wanted to explore the past. As a palaeobiologist, she is fulfilling her lifelong dream. When we are facing unprecedented challenges of global change and social unrest, why should we care about some long dead bones? By looking at fossils, we can see through to the past. The sun that shines upon us today rises over a very different Africa than it did in prehistory. Some species of the past are now extinct but their resilient relatives forged on to give rise to species we see today. Palaeoscience helps us understand things of the past and better understand modern biodiversity, model long term patterns and help us make informed decisions about our future. When we face challenges of an unpredictable future we need only to look in our past and be reminded that life does indeed find a way.

Blood sugar and insulin level have highs and lows throughout the day. Food scientists use a tool called the glycaemic index (GI) to rate how carbohydrate foods boost blood sugar levels. High GI foods, such as doughnuts and white bead, have a GI from 75-100. Low GI foods have a GI less than 55. This includes all-grain foods, like brown rice and brown bread. A key food component that can be used reduce the carbohydrate load of food is fibre. Fibre is an edible part of a plant, which is not digested in your small intestine but travels to the large intestine where it is broken down by micro-organisms to release a compound called short chain fatty acids and helps to release a steady flow of sugar in the blood throughout the day. The World Health Organisation recommends an adult should consume 29- 40 grams of fibre per day, but South Africans consume only about 10 grams per day. Oluwatyoyin’s research aims to bridge this fibre gap, by introducing fibre from wheat bran and oat bran into a popularly consumed, deep fried dough snack called ‘amagwinya’, which is made from wheat flour, sugar, water and yeast. ‘Amagwinya’ has a high oil and high carbohydrate content. In the lab, ‘amagwinya’ has been enriched with an oat and wheat bran and GI levels measured. The ‘amagwinya’ without bran had 80 GI and while the one with bran had 56 GI, which means adding bran lowers the GI level from a high GI to a medium GI. This could help us reach our target for fibre each day.

About 256 million people worldwide suffer from anxiety and depression. These diseases are often interlinked, with 50 percent of people who suffer from depression also suffering from anxiety. Sufferers take medication for a very long period of time, and they need to find the right medication that works for them and does not cause bad side effects. From 1980 to 2019, 42 percent of new medication or drug leads were developed from natural products. South Africa has 10 percent of global plant diversity and also has rich African tradition knowledge systems and cultures that may hold secrets to help with the mental health pandemic. The plant that Kaylan researches is called Sceletium or ‘kanna’ and ‘kougoed’. It is the most researched medicinal plant for anxiety and depression in South Africa. His research analyses the chemistry of the plant on the computer before going to the lab for testing. By creating the exact replicas of the parts of the brain that control anxiety and depression on the computer, one can analyse which compounds of the plant bind most tightly, which may be toxic and which may have the best effects. By first looking at African traditional medicine, then using a computer to see which compounds may be best to help, the amount of time spent testing compounds in the lab can be reduced. Instead of testing a thousand, we may test only the top five candidates from the results on the computer. Through these methods we will get much needed medications to the frontlines of the global mental health pandemic.

Nelisiwe’s research is working on a solution that helps to detects if a document is fake, through methods that show if there are illegal changes on a document. This is important, for example, for employers who need to verify qualifications. Vital pieces of information on an original document can be selected using coordinates. These coordinates locate text on the document, then a hash function takes in the vital pieces of information and converts these into a single value that cannot be reversed, known as the cryptographic hash. The cryptographic hash is stored in a database to be used later in the verification process to check if the document passes verification or fails. The vital pieces of information are converted into checksum and, along with the coordinates, are stored in the barcode printed on the document. The checksums and the coordinates help to locate exact words that may have been changed in a document and even highlight it.

Lake Malawi is shared by three African countries namely; Mozambique, Tanzania and Malawi, and supports the livelihood of more than 1.6 million people. Lake Malawi has the greatest number of freshwater fish species in the world and people travel from all over the world to see them. However, ten percent of the fish species are at risk of extinction, due to pollution, over-fishing and habitat destruction. We need to protect them. Scientists can help by placing cameras underwater in different parts of the lake to monitor the different groups of fish in the water. This helps them find out where each species spends most of their time in the water and enables them to count the numbers of different populations to see how they are changing overtime. This information will show which species need immediate help, and which areas that are most important to them need protecting to help their population recover. It also helps us to create plans to use the lake sustainably so that the fish can be around for years to come and continue supporting the livelihoods they do.
