The development of a strain of grass pea that is safer to eat in the large quantities consumed by some poorer populations in Africa highlights the point that “research for the long-term relief of hunger in Africa must contemporaneously address issues of toxicology as well as those of plant science and nutrition.” The recently released plan from the National Marine Fisheries Service for saving endangered salmon of the Columbia River is discussed by several of those involved with the issue. And an international collaboration to establish thyroid tumor tissue banks in the three states most directly affected by the Chernobyl nuclear accident is described.
