The last natural nuclear fission reactor
Article Abstract:
All the 14 natural fission reactors discovered in the uranium deposit at Oklo, in Gabon's Franceville basis, have now been partially or completely mined. There are no other known natural fission reactors on Earth, and future work in this field will therefore have to be undertaken on the basis of previously collected samples. Many of these are unreliable, making it impossible to analyze the behaviour and migration of fission products and actinides. The only real hope for future work on this subject is a reactor situated in the very small uranium deposit of Bangombe, where mining has not yet taken place.

Idiotype/granulocyte-macrophage colony-stimulating factor fusion protein as a vaccine for B-cell lymphoma
Article Abstract:
A cancer vaccine comprised of malignant B cell-derived idiotype fused to granulocyte-macrophage colony-stimulating factor (GM-CSF) was tested in mice. GM-CSF is known to enhance antigen-presentation in many cells. Linking it to tumor-specific idiotypes could be a means of inducing an immune response against tumors, or conferring immunity against certain types of cancers. The results showed that the idiotype/GM-CSF strongly induced idiotype-specific antibodies even without other carrier proteins or adjuvants. The approach can also be useful in developing vaccines against other types of diseases.
