A portal for RNA exit
Virus particles are metastable: they must be highly stable, to protect the nucleic acid while traveling from host to host or cell to cell, and then come apart to liberate the genome into the cell. New insight into this uncoating process comes from beautiful images of feline calicivirus showing formation of a portal on the […] (Source: virology blog)

Science publishing has a Zika problem
Science publishing has a problem. I agree with Nobel Laureate Randy Schekman, who wrote that prestigious science journals like Cell, Nature, and Science – which he calls ‘luxury journals’ – are damaging science.  The succession of articles on Zika virus nicely illustrates this problem. The big three in science publishing – Science, Nature, and Cell – have published many papers on Zika virus since the beginning of 2016. Many of these have had a turnaround time of a week or two – the time between when the papers were submitted, and when they were published online. A rapid turnaround time is...

TWiV 312: She sells B cells
On episode #312 of the science show This Week in Virology, the TWiVbolans discuss the finding that human noroviruses, major causes of gastroenteritis, can for the first time be propagated in B cell cultures, with the help of enteric bacteria. You can find TWiV #312 at www.twiv.tv. (Source: virology blog)
