    Contents: Astronomy for Africa - The International Year of Astronomy 2009 is important to Africa, celebrating the continent's long history of astronomy and our world-class research facilities: The history of the Universe: cosmology up to 1995 - Cosmology is the grandest study of all, asking the really big questions, such as how the Universe began, which we have only begun to unravel in the last 90 years: Dark energy: cosmology since 1995 - The Universe is not only expanding, but it is accelerating as it does so, under the influence of a dominant energy form that no-one has yet seen: Is there somebody out there? Are we alone in the Universe or is there life elsewhere? - Since the early 1990s we have had the technology to search beyond our own Solar System for extra-solar planets: Black holes in our Galaxy and beyond - Black holes are no longer the stuff of science fiction stories or even just theoretical constructs, but objects that are present in the Universe in some numbers, even in the centre of our own Galaxy: The Milky Way and other galaxies - We sit inside the Milky Way, just one of many galaxies in the Universe; some spiral and some elliptical, but all fascinating: The life and death of stars - The Sun is our nearest star and without it the Earth would be a very different place, but there are countless numbers of other stars. which have been forming and dying over the ages: Big eyes on the stars - Humankind has been looking at the stars for centuries, but in the past few decades the technology to do so has become more and more complex, providing us with more and more information: When a crocodile eats the Sun - Indigenous astronomy - Africa has a long history of astronomy, shown by rock engravings by the San people and the rich heritage of the Timbuktu manuscripts: MeerKAT coming on track during IYA2009 - South Africa has put in a bid to host the Square Kilometer Array, an array of telescopes that will help to answer the big questions about the Universe and the MeerKAT, the Karoo Array Telescope may form its core: The physics behind astrophysics - Physics is not just a dry, academic subject, but the backbone of the exciting world of astronomy and astrophysics: When the light goes out: Pluto and Charon - Astronomers have developed techniques that allow us to characterise distant objects in the Universe that cannot be observed directly: Astronomy at the Cape - As with many other things, the Cape has a long history of astronomy, initially developed through the necessity to find ways to successfully navigate past it:The Department of Science and Innovation: Academy of Science of South Afric

[Online] Available at: DOI http://dx.doi.org/10.17159/assaf/0016This Forum on Local Economic Development in Small Towns, Housing Delivery and Impact on the Environment is the second in a series that are being convened by the ASSAf Forum Committee on Science for Poverty Alleviation. Noting that poverty is a major issue of concern in South Africa; it is a very broad topic that can be addressed as a combination of selected elements. Local economic development in small towns, several cases on this important topic has been tried. The purpose of this workshop was therefore to bring all these cases together and critically address them as a whole. The plenary decided to structure the workshop to consider the following issues that would guide the national strategy: The population in small towns; Creating entrepreneurship culture amongst the youth; Infrastructure and resource development, e.g. railway lines, artisan schools, etc; and look at economic versus physical model approach. The outcome of the workshop is therefore not necessarily a strategy but rather a methodology of how ‘local economic development in small towns’ can be achieved.United States National Academies Academy of Science of South Afric

This publication was prepared for the Fifth Annual Meeting of the African Science Academy Development Initiative (ASADI), hosted by the Ghana Academy of Arts and Sciences on 10-11 November 2009 as part of its 50th anniversary celebration. ASADI is a project funded by The Bill & Melinda Gates Foundation through the United States National Academies to strengthen African academies of sciences in advising their national governments on matters of science and technology. This report includes data for all of sub-Saharan Africa but focuses specifically on the seven countries participating in ASADI.Bill & Melinda Gates Foundation through the United States National Academies to strengthen African academies of sciences

    Revitalising Clinical Research in South Africa

[Online] Available at: DOI http://dx.doi.org/10.17159/assaf/0036Clinical research in a developing country like South Africa contributes to health care at all levels by identifying the causes of problems, facilitating diagnosis, improving the efficiency and effectiveness of care, and promoting good policy-making. It also supports the training of competent health professionals of all kinds, and contributes to global knowledge about locally, as well as generally, prevalent diseases in terms of prevention and treatment. The key narrative of clinical research in South Africa over the last two decades has been that of a largely unplanned, but cumulative, disinvestment in publicly funded programmes, resulting from the withdrawal of the health departments of provincial governments from this sector (academic hospitals are now funded for service functions only), the absence of discounts for research tests from the business model of the National Health Laboratory Service (NHLS), chronic underfunding of the Medical Research Council (MRC) despite its obviously important mandate for maintaining and developing medical/ clinical research capacity in the country, and the lack of funding streams to universities that might in principle have been applied to meet the overall shortfall in support. These intersecting developments are a kind of ’elephant in the room’, well known to all participants, but very poorly documented. Tertiary service units struggle to remain active in research, and to translate their expertise into improved health service. As a result, many clinical researchers have been left with no option but to turn to the pharmaceutical industry for the funding of those clinical trials in which the companies concerned have an interest, or to international donors who conduct large-scale, short-to medium-term, projects in South Africa, with local researchers drawn into international teams, often led by outsiders. The pharmaceutical investment is directed predominantly at the profitable areas of chronic diseases of lifestyle, mental illness and allergy, while most of the external donor funding is directed at the serious local HIV and TB pandemics. Local and international clinical conference activity has accordingly begun to reflect the agendas of donors and industry. There is little likelihood that continuation of the present situation is compatible with rebuilding and sustaining solid research capacity in the clinical domain, nor can the ideal of well-coordinated state support for a health system, built on the ‘intelligence’ of good clinical research, ever be realised. The serious decline in clinical research activity and capacity has prompted this study by ASSAf (http://www.assaf.org.za) in order to make recommendations on the overall revitalisation of clinical research in the country within the broad paradigm of essential national health research. An additional stimulus is the emphasis of government in its ten-year science and technology plan on the development of new medicines and other biologically useful agents (‘farmer to pharma’).1.

TWAS is the largest and most significant individual-based, multinational science academy in the world. The visit to South Africa of some of the world’s most eminent scientists from the developing world provides an opportunity to profile science in our country. Through the publication of this book we hope to reflect on the state of science in South Africa; to consider the historical context and the key features that have shaped scientific research in the country and are determining its current trajectories; to highlight some of the future challenges and opportunities; and to celebrate some of the achievements of South African scientists.Academy of Science of South Afric
