AFRICAN VERY LONG BASELINE
Nine African partner countries are members of the SKA AVN, including Botswana, Ghana, Kenya, Madagascar. An important part of the effort to build SKA on the African continent over the next decade is to develop the skills, regulations and institutional capacity needed in SKA partner countries to optimize African participation in the SKA,' says the South African Minister of Science and Technology. , Mrs. Naledi Pandor.
INTERFEROMETER (VLBI) NETWORK (AVN)
METHANOL MASER DETECTION
The station was commissioned on August 12, 1981 and operated by the Ghana Telecommunications Corporation until July 3, 2008, when Ghana Vodafone took over as major shareholder, with a 70% share in the station. The SKA SA/HartRAO team assessed the suitability of the 32 meter Beam Waveguide antenna and the Kutunse control station for radio astronomy during two consecutive working visits in March and May 2011.
PULSAR
Growing technological skills Building on the success of the Leverhulme-Royal Society programme, a joint UK-South Africa Newton Fund intervention (Development in Africa with Radio Astronomy (DARA)) has since been launched in other partner countries to develop high-tech skills which can lead to a broader economic development in Africa. Ghana's radio telescope The Ghana Intelsat Satellite Earth Station at Kutunse is located at an altitude of 70 meters above sea level.
OBSERVATIONS
Future developments may include expanding the capacity of the newly refurbished radio telescope to cover more VLBI bands. Radio continuum flux measurements are measurements of the broadband radiation emitted by celestial objects in the radio part of the spectrum.
HOW TO CONVERT A SATELLITE DISH INTO
For the VLBI component, the station must be able to map interstellar masers in star-forming regions in the Milky Way and determine the distances to star-forming regions in the Milky Way using methanol. JIVE ERIC scientists in the Netherlands and the wider European network have added tremendous value through Dr. Jay Blanchard, Supporting Scientist for the JUMPING JIVE project.
PROTECTING WOMEN AGAINST HIV
EDUCATION AND EARLY LIFE
Legends
South African
Quarraisha Abdool Karim
At the time, HIV studies were limited and limited to research on the migrant mining population in South Africa. This highlighted the potential problem of the rapid spread of HIV in South Africa's poor communities.
STEERING SA’S AIDS RESPONSE
She established the MRC AIDS program in KwaZulu-Natal in 1989 and conducted one of the first community-based epidemiological studies of HIV infection in South Africa in 1990. Quarraisha Abdool Karim's data also showed that infection rates were much higher among women than men and that worryingly, young women became infected in their teens, while men tended to become infected in their late 20s. She realized that this indicated that HIV was spreading between older men and younger women, clearly identifying teenage girls as a particularly vulnerable group at risk for HIV.
THE HUNT FOR A MICROBICIDE
Nevertheless, the CAPRISA 004 trial has breathed new life into the field of microbicide research and HIV prevention in general. Abdool Karim is also leading studies to see if social incentives can help reduce HIV infection rates, particularly among teenagers in KwaZulu-Natal. Another of her studies examined whether voluntary male circumcision programs, which have been shown to reduce HIV infection rates, can be implemented in schools and define the provision of sexual reproductive health services to school-age adolescents and young women.
BREATHING LIFE INTO THE BONES OF
New female-controlled prevention methods are being tested in CAPRISA's clinics, including a vaginal ring containing the antiretroviral dapivirine and an injection of a new class of ARV drug called integrase inhibitors. These may be more user-friendly methods of prevention for some women, as they can provide protection for a month or longer.
Anusuya Chinsamy-Turan
BONE PI
This is one of the many discoveries of new species in which she participated. As soon as I looked at the bone parts under the microscope, I knew that our findings were important - a breakthrough, the journal Nature," she remembers the impression made by the special organizational structure of the bone. Chinsamy-Turan worked on dinosaurs and other fossils from various places in South Africa, Africa and other parts of the world.
TELLING SCIENCE AS IT IS
The actual growth dynamics of the fossilized animal are recorded within the microscopic structure of the fossilized bones – similar, but not exactly, to those of tree rings. It was at the end of her first postdoctoral year at the University of Pennsylvania in the US, and by then she was already one of the few people with expertise in the microstructure of fossil bones. She began collaborating with Luis Chiappe, then of the American Museum of Natural History, to examine three early bird specimens from Argentina.
SUCCESS IS THE ONLY OPTION
The first has its roots in the two-year leave of absence she took in 2001 and 2002 to work as Director of the natural history collection division at the Iziko Museums in Cape Town. This former Vice-President of ASSAf and President of South African Women in Science and Engineering (SAWISE) was also at the helm when the Department of Biological Sciences at UCT was formed through the merger of the two departments. Being a board member of the Jurassic Foundation and Chair of the prestigious Romer-Simpson Award of the US-based Society of Vertebrate Paleontology are among her current commitments.
Tebello Nyokong
Ultimately, it is her mission and its various aspects that drive her forward: to breathe life into an extinct animal and find enough detail to make its life story as true as possible. Master's degree from McMaster University in Ontario, followed by a PhD in Chemistry from the University of Western Ontario in 1987. In 1990, she also received a Fulbright scholarship to conduct postdoctoral research at the Radiation Laboratory of the University of Notre Dame in the USA.

The Faculty phased in the Master of Engineering (M Eng) and Doctor of Engineering (D Eng) qualifications in 2017. The research shows that the rock art of the region is much older than previously thought. The success of this project is based on very careful chemical characterization of the composition of the paint and contaminants on the rock.
A new study from Australia National University (ANU)
Urbanization and the electrification of homes does not reduce the amount we sleep, finds a new study in the journal Scientific Reports. In this study, researchers from the University of Surrey, in collaboration with groups in South Africa, Brazil, Colombia and the USA, investigated the sleeping patterns of people from two neighboring communities in Mozambique – the small electrified urban town of Milange and the non-electrified rural community of Tengua. During the study of a number of aardvarks by researchers from the brain function research group at the University of the Witwatersrand, all but one of the study animals - as well as other aardvarks in the area - died due to a severe drought, with air temperatures. much higher than normal and very dry ground in the area.

Tracking an octopus
Having spent years with the master trackers of the desert, the Kalahari San, he was well prepared. He spent a lot of time in nature, but it was while staying with the San and hunting that he realized that his access to the ecosystem, to the biology, was actually quite restricted compared to theirs. From the octopus (Foster named her Super Star) he learned how to move so he wouldn't give off shock waves.

By cannibalizing the eggs, larvae and pupae of native ladybirds, the harlequin ladybird has become the leading cause of native ladybird decline in Britain. They only exist in the damp seepage waters on the mountains of the Cape Peninsula – nowhere else in the world can you hear their cheerful chirping. Very little is known about their ecology and their functional role in the specific environment in which they occur.
THE SOLUTION?
Providence can come in many forms, and on one memorable day it came in the form of two bars of grain buried under the heavy field gear in my 70 L hiking bag. That day on the mountain, cold as it was and hungry as we were, it was another great field day spent in the fynbos recording the calls of the small Cape Peninsula moss frog, Arthroleptella lightfooti. Changes in their population may indicate a change in the condition of the fynbos and may draw our attention to the management practices that should be implemented to preserve this unique biome.
