Author name: Vincent Racaniello

I'm Professor of Microbiology and Immunology at Columbia University in New York. I run a research lab where we study poliovirus, rhinovirus, and other RNA viruses. I also love teaching about viruses - check out virology.ws, microbe.tv, or iTunes University for some of my offerings. I want to be Earth's virology professor.

Planaria and mollusks yield the biggest RNA virus genomes

2 Comments / Basic virology, Information / By

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 tenth. This situation has now …

Rhinoviruses have a sweet tooth

2 Comments / Uncategorized / By

Viral infections often lead to alterations in the energy-generating and precursor synthesizing pathways of a cell, to provide the building blocks and energy to produce new virus particles. The latest example is rhinovirus: infected cells mobilize glucose from extra- and intracellular pools, which is essential for viral replication.
