A scientific researcher manipulates drops of embryonic stem cells in a laboratory, at 'Hospital do Coracao' heart institute, in Sao Paulo, Brazil, on 5 March, 2008. Brazil's Federal Supreme Court will decide today on the continuity of the stem cells research, after Roman Catholich church officials and anti-abortion groups urged to ban it, given that the stem cells extraction entails the destruction of the embryo.
