Here am I, writing a not-so-brief history of the the discovery of viruses, and I miss The Centenary of the Phage! How did THAT happen?! 423 more words

RNA as genetic material
While it had been known since Bawden and Pirie’s work in 1937 that TMV particles contained RNA, followed later by a number of other viruses, it must be remembered that DNA had only really been accepted as the genetic material of cells and viruses after the Hershey-Chase experiment in 1952 and the Watson-Crick… 3,258 more words
The Phage Group and the birth of molecular biology
Some of the more fundamental discoveries in modern biology were facilitated either by the study of viruses, or by use of viruses as tools for exploring host cell mechanisms. 1,618 more words
Scientists at the Institut Pasteur in France who are tracking the Ebola outbreak in Guinea say the virus has mutated.
I would be surprised it there weren’t evidence by now of adaptation to humans: never in any previous outbreak of EHD has the person-person chain of transmission been sustained for so long, meaning never before has there been the opportunity for human-specific adaptations to become established.184 more words
More Surprises in the Development of an HIV Vaccine
In the current issue of Frontiers in Immunology, Jean-Marie Andrieu and collaborators, report results from non-human primate experiments designed to explore a new vaccine concept aimed at inducing tolerance to the simian immunodeficiency virus (SIV) (1).292 more words
Researchers create a phylogenetic tree of insects by comparing the sequences of 1,478 protein-coding genes among species.
Using an unprecedented quantity of genetic sequence information from insects, researchers have assembled a new phylogenetic tree showing when these invertebrates evolved and how they are related to each other.172 more words
Dr Linda Stannard was a virologist and electron micrsocopist of some repute, here at the University of Cape Town, when she retired some years back. She worked on a lot of interesting viruses, thanks to the diagnostic Virology lab at UCT’s Medical School as well as an eclectic mix of colleagues, and managed to create some stunning images of everything from TMV to poxviruses, herpesviruses, poliovirus, rotavirus, hepatitis B and adenoviruses. 75 more words
