Dorian Gray mice

Article Abstract:

Tithonin is responsible for the carp's capacity for perpetual growth. The gene coding for tithonin (tith) has been isolated, and genetically modified to overcome senescence in transgenic mice. The most successful demonstration of this was achieved by using the tith gene from Japanese Koi carp living in thermal springs on Mount Asama. As a result of these findings, there is now the possibility of producing senescence-resistant transgenic cattle, as well as a possible cure for Zachary's progeria. However, the moral implications of these findings has raised alarm on the possible dire consequences of pursuing this line of research.

From Pan to pandemic: Further evidence that HIV-1 originally came from chimpanzees bears on a variety of issues - the evolution of AIDS viruses, disease transmission from animals to humans, and chimpanzee conservation and welfare

Article Abstract:

Gao and colleagues have provided evidence that HIV-1 was transmitted to humans from the chimpanzee, Pan troglodytes harboring the related simian immunodeficiency virus, SIVcpz. The three SIVcpz strains most closely linked to HIV-1 may well have come from the single subspecies, Pan troglodytes troglodytes. Chimpanzee numbers are falling due to habitat loss and hunting. Fieldwork with free living apes provided the information for Gao's work and further fieldwork linking demographic data and biomedical monitoring could also be productive.
