A study of South Africans infected with both HIV and tuberculosis (TB) has found that starting antiretroviral (ARV) therapy during TB therapy can improve survival rates. Researchers found that death rates more than doubled when ARV treatment was delayed until the completion of TB treatment.
A new generation of sophisticated Earth models is gearing up for its first major test. But added complexity may lead to greater uncertainty about the future climate.
The disproportionate distribution of environmental risks among the population is known as environmental justice, environmental equity or at some instance environmental racism. All these terms in fact define the status that the poor suffer greater exposure to environmental pollution than other communities.
Hopes for the development of pebble-bed nuclear reactor technology, long held up as a safer alternative to conventional nuclear power, have suffered a blow. The South African government confirmed that it will effectively stop funding a long-term project to develop the technology.

Although fisherman routinely fight bans on fishing, studies indicate that the creation of protected marine reserves in key areas can both raise the profits of fishermen and boost fish populations. Marine reserves could help to make nearby fisheries profitable by acting as nurseries for fish larvae that are later spread by ocean currents, for example.
Climate change is a term that almost every educated person uses today. Hot days, as summer approaches, are quickly interpreted as tangible signs of global warming. Sudden, unanticipated events like torrential downpours
Treating HIV infection aggressively before symptoms appear could help to control the spread of the disease, according to data presented at a retroviral conference. Independent studies in Canada, the United States and Africa support the strategy in both the developed and developing world.
The rapid increase in the science and implementation of marine protected areas (MPAs) around the world in the past 15 years is now being followed by similar increases in the science and application of marine ecosystem-based management (EBM).
