Jul 17 -- There have been numerous accidents in the North Pacific's major shipping lane through Unimak Pass in Alaska's Aleutian Islands, including when the Selendang Ayu ran aground in 2004 during a severe storm and spilled more than 300,000 gallons of heavy fuel oil. A new National Research Council report presents a framework for conducting a comprehensive risk assessment of ship accidents and spills to better manage safe shipping operations in this region.

Jun. 20 -- The Ugandan government recently started spraying insecticides in homes and settlements to combat mosquitoes that spread malaria, the country's leading cause of death. A new report from a committee of the Uganda National Academy of Sciences (UNAS) says that as the spraying continues, the government needs to monitor mosquitoes for resistance to insecticides, and manage the spraying program in ways that minimize resistance. UNAS is a participant in the African Science Academy Development Initiative, a joint effort of several African academies and the U.S. National Academies to advance science-based policy advice in Africa.
