East Texas Health Organization Sees Increase In HIV Cases
Officials at an East Texas health care organization, Health Horizons, which provides HIV testing and other services to people in 12 counties, "has seen more East Texans test positive for [HIV] so far this year than it did for all of 2008," the Lufkin Daily News reports. Executive Director Wilbert Brown said, "We"ve had eight people out of more than 800 test positive for HIV in the first seven months of this year. Most of those have been African-American men. Last year we had a total of six out of more than 1,000. I expect us to see two or three more positives before the year is out. The state average for testing positive is one in 100, and we"re getting close to that number." According to the article, "Brown said he attributes the increase to Health Horizon"s aggressive outreach program targeting high-risk groups and to people realizing the importance of getting tested." The Daily News article also profiles a client of Health Horizons (Cooley, 8/2)

Isotopes, The Atomic Clues Used To Solve Crimes, Date Ancient Artifacts And Identify Chemicals
Whether it"s the summer grass that tickles your feet or the red Bordeaux smacking on your palette, nearly every part of the world around you carries special chemical markers. These markers, called isotopes, can tell scientists where the molecules that compose a substance are from, where they traveled, and what happened to them along the way. But doing these analyses has been complex and costly. Now, Stanford chemists have developed a new method to make isotopic analysis easier and less expensive.

Fighting The Challenges Of Poverty

It is estimated that 1.4 billion people live in extreme poverty, on less than $2 a day. In 2000, 189 nations declared that they would "free all men, women, and children from the abject and dehumanizing conditions of extreme poverty". These nations signed up to Millennium Development Goals (MDGs) to combat poverty by 2015. To help meet these complex challenges and "make poverty history" more knowledge and evidence is needed. A launch event Wednesday 22nd July 2009 at the Department for International Development (DFID) marks a new phase of research collaboration between the Economic and Social Research Council (ESRC) and DFID which will provide more robust social science research to address poverty alleviation amongst the poorest countries and peoples of the world. Focusing on the key theme of "Social Science Research for Development: Why it Matters", the launch event will provide an opportunity to hear the role of social science research in development from key speakers followed by an opportunity for questions and open discussion. The debate will then be followed by a networking drinks reception providing an opportunity to meet representatives from DFID and the ESRC, scheme award holders and commissioning panel members, members of learned societies and NGOs from the international development community. The scheme, initially launched in 2005, has already funded ÷£13.5million of world-class research on economic development and quality of life in less developed countries which is being used to inform policy and practice for poverty reduction. This phase of funding has a total budget of ÷£23 million for research on international development. Under an overall theme of "poverty alleviation" three thematic areas have been highlighted which are of particular interest. These highlight areas cover: * Security, Conflict and Development; research and analysis to better understand how violent conflict and insecurity constitute a fundamental challenge to development. * Economic Crisis, Poverty and Growth: the Implications for Development Theory and Practice; the current economic crisis is predicted to force a further 90 million people into poverty. Research is needed to revisit existing economic theory to identity interventions and policy options which will help to ensure progress towards the MDGs. * Cities and Development Half of the world"s population already lives in cities, a third of these live in slum conditions. The UN estimates that by 2030 the number of city inhabitants will be over five billion. New thinking and innovative research is urgently required to respond to the challenges and opportunities of these social changes. The scheme as it is open to applications from researchers based anywhere in the world. ESRC welcomes applications from developing countries as both lead and partners in bids for research funding. As well as research excellence, all applicants will have to demonstrate that their research outputs have the potential to inform strategies to reduce poverty.
