In science news around the world this week, attorneys sought to prevent 9000-year-old bones from being handed over to American Indians; a senior U.S. health official disputed charges that the government tried to prearrange an advisory panel's recommendation to publish two studies that describe how to make the H5N1 avian influenza virus transmissible in mammals; the Philippines National Academy of Science and Technology blasted Greenpeace for trying to stop field trials of a genetically modified eggplant; a pilot project will share abandoned drugs with academic researchers so that they can look for new uses; a new study of the links between atmospheric chemistry and climate change kicked off; the British government has enlisted the help of Wikipedia founder Jimmy Wales to figure out how to make research information more easily accessible; and a tobacco research project nominated for a prestigious Chinese science prize has been withdrawn from further consideration.
