Analysis of polio vaccine could end dispute over how AIDS originated
Article Abstract:
Clayton Black, director of the Wistar Institute in Philadelphia, PA, will open a locked fridge containing some of the last remaining samples of an oral polio vaccine given to many Africans in the 1950s. These samples will be sent to three laboratories to establish whether they contain any trace of infection with a precursor of HIV. A leading mitochondrial DNA analysis laboratory will also attempt to identify the primate species used to prepare the samples. It is hoped that this will produce more information about whether HIV-1 passed to humans from contaminated polio vaccines distributed in central Africa during the 1950s.

Dispute over 'threshold' explosions could disrupt test ban negotiations
Article Abstract:
The Comprehensive Test-Ban Treaty (CTBT) has fixed a minimum threshold below which nuclear explosions by the nuclear weapon states will be exempted from the indefinitely extended Nuclear Non-Proliferation Treaty (NPT). The CTBT has raised serious concerns among the non-nuclear weapon countries that have signed the NPT as it prevents them from developing nuclear capabilities but allows the nuclear weapon countries to use some of their potentially dangerous nuclear arsenal.

AIDS vaccine 'needs focused effort' as drug firms back off research
Article Abstract:
Scientists worldwide believe that governments should pursue research on the development of a vaccine that would avert the onset of AIDS or its spread because private pharmaceutical companies seem unwilling to invest their time and resources to the undertaking. Current research on the matter is sorely lacking in focus. More attention should be given to the development of therapeutic vaccines.
