During the replication of retroviruses, a double-stranded DNA copy of the viral RNA genome is synthesized by reverse transcription and integrated into the genomes of the infected cell. When retroviral DNA is integrated into the DNA of germ line cells, it is passed on to future generations in Mendelian fashion as an endogenous provirus. Until …
Influenza researcher Peter Palese visited yesterday and spoke about “Pandemic influenza: Past and Future”. A key part of his talk was a review of his efforts to produce a universal influenza vaccine which protects against all strains. He used the following graph to make the point that when influenza pandemic strains emerge, there is insufficient …

A salt-loving (halophilic) bacterium which can grow in medium containing arsenic instead of phosphorus has been selected from the microbial community of Mono Lake in California. Arsenic (As) is a chemical analog of phosphorus and is usually toxic because it can enter metabolic pathways in the place of phosphorus. It appears to be incorporated into macromolecules of …
