The acquisition of a capsid is thought to be a key event in the evolution of viruses from the self-replicating genetic elements that existed during the pre-cellular stage on Earth. The origin of viral capsids has been obscure because their components are not similar to cellular proteins. The discovery that a viral capsid protein evolved from …

On episode #366 of the science show This Week in Virology, Vincent visits Melbourne, Australia, where he speaks with four PhD students about their research projects and what it’s like to get a doctorate down under. You can find TWiV #366 at www.microbe.tv/twiv. Or you can watch the video below.
Johns Hopkins Neurovirologist Richard T. Johnson has died, and his obituary at Hub provides a good summary of his career. He had an important influence on my work early in my career. The first edition of Dr. Johnson’s book, Viral Infections of the Nervous System, was published in 1982 – the year I began my laboratory …
On episode #365 of the science show This Week in Virology, Vincent, Alan, and Kathy trace the feud over genome editing, a new virus discovered in human blood, and the origins of hepatitis A virus. You can find TWiV #365 at www.microbe.tv/twiv.
On episode #364 of the science show This Week in Virology, Vincent, Rich, and Kathy speak with Ralph Baric and Vineet Menachery about their research on the potential of SARS-like bat coronaviruses to infect human cells and cause disease in mice. You can find TWiV #364 at www.microbe.tv/twiv.
A study on the potential of SARS-virus-like bat coronaviruses to cause human disease has reawakened the debate on the risks and benefits of engineering viruses. Let’s go over the science and then see if any of the criticisms have merit. The SARS epidemic of 2003 was caused by a novel coronavirus (CoV) that originated in …
