Planaria and mollusks yield the biggest RNA virus genomes
By Vincent Racaniello
The development of high throughput nucleic acid sequencing tools has rapidly increased the pace of virus discovery in the past 20 years. Yet in that time, while the largest DNA genomes have increased by nearly ten times, the largest known RNA viral genome has only increase in size by a ...
TWiV 508: Bioweapon
By Vincent Racaniello
Jens Kuhn returns to present a brief history of bioweapons, with a focus on the program in the Soviet Union, the largest ever undertaken, and his experience working in the decommissioned Soviet bioweapons laboratory known as Vector. <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: ...
Rhinoviruses have a sweet tooth
By Vincent Racaniello
Glucose metabolism. After transport into cells via glucose transporters (Gluts) and phosphorylation by hexokinase, glucose can enter glycolysis or the pentose phosphate pathway for nucleotide synthesis. Glycolysis produces 2 molecules of pyruvate from 1 of glucose, with a net energy yield of 2 ATP and 2 NADH. Image credit. Viral ...

TWiV 507: The fusion of form and function
By Vincent Racaniello
The TWiV team discuss the biology of Ebola viruses, and how localization of the membrane proteins of vaccinia virus drive function: the fusion machinery sits at the tips of virions, and binding proteins are at the sides. <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; ...
