The large quantities of viral macromolecules and virus particles that are produced in an infected cell impose heavy demands on the host. Synthesis of the building blocks of a virus particle – nucleotides, amino acids, and sometimes fatty acids – requires energy, typically in the form of ATP. Synthesis of viral proteins and genomes, and …
Nels joins the TWiV team to talk about his work on genomic accordions in vaccinia virus, hepatitis B virus in a 439 year old mummy, and viral induction of energy synthesis by a long noncoding RNA. <span data-mce-type=”bookmark” style=”display: inline-block; width: 0px; overflow: hidden; line-height: 0;” class=”mce_SELRES_start”></span><span data-mce-type=”bookmark” style=”display: inline-block; width: 0px; overflow: hidden; line-height: …
A study done in 1985 on a 16th century Italian mummy suggested that the two year old child had smallpox. Recent sequence analysis of tissues from the mummy now reveal the presence of hepatitis B virus, not smallpox virus. The sequence of the viral genome suggests that HBV entered the human population well before 1500.

The discovery of Mimivirus in a French cooling tower amazed virologists and changed our view of the biology and evolution of giant viruses. Since then, many other giant viruses have been identified, and with three exceptions, they all appear to infect species of Acanthamoeba. Now a new member of the Mimivirus family has been discovered …
