Breaking the brain-blood barrier
Article Abstract:
Johansson and colleagues have shown that cells in the ependymal lining of adult brain ventricles could be multipotent, generating new neurons and glia. They proposed that the ependymal stem cell asymmetrically divides resulting in one daughter cell, and another cell that moves into the subventricular layer giving rise to a progenitor cell pool, providing the source for neuronal and glial precursors. Bjornson and colleagues have also described similar cells regenerating blood tissues following transplantation into an irradiated mouse.

France's blood scandal draws blood
Article Abstract:
Four former French government officials have been convicted of fraud for failing to use heat-shock treatment to eliminate the HIV virus from transfusion blood in 1985. This failure caused hundreds of people, many of them hemophiliacs, to develop AIDS after receiving some of the tainted blood. Although the French public is justifiably outraged by this criminal behavior, the government should not let the demand for punishment deter it from investigating the bureaucratic machinery that allowed the tragedy to happen.

Justice unevenly spread in Paris
Article Abstract:
Michel Garretta and Jean-Paul Allain were certainly guilty of not stopping the distribution of HIV-contaminated blood in 1984 and 1985, but Parisian courts did not raise the question of what people or institution pressured the two to keep silent. The trials confirmed the duty of knowledgeable people to blow the whistle when they see wrongdoing, but ignored the consequences to those individuals. Government influence was a large part of the conspiracy of silence.
