Guest host Lynda Coughlan reviews how oncolytic viruses, which specifically kill tumor cells, are designed and how they work.

Polio returns to Nigeria after two years – but it turns out it had never gone away.

On this episode of Virus Watch we cover three Zika virus stories: the first human trial of a Zika virus vaccine, the first local transmission of infection in the United States, and whether the virus is a threat to participants in the 2016 Summer Olympic and Paralympic Games.

The first experimental Zika virus vaccine has been published, and in this episode of Virus Watch, I explain how it works – it’s a DNA vaccine – compared with all the other vaccines out there.

In this Virus Watch video, I answer the often-asked question that always leads to an argument: Are Viruses Alive?

In this episode of Virus Watch, I’ll show you how mosquitoes spread viruses. We’ll look at how a mosquito finds a host, how it finds a blood vessel, and how it delivers viruses to a new host. Don’t blame mosquitoes for viral diseases: it’s not their fault!

Three papers have been published showing that Zika virus can cross the placenta in mice, replicate in the fetus, and cause microcephaly. In this episode I summarize these data and their implications.

In this video from Virus Watch you’ll see how the Zika virus particle is built, and how it binds to an antibody that blocks infection. All in gorgeous three dimensional views provided by recent structure studies.

Virus Watch is a new weekly video series that explores the amazing world of viruses. This week: the latest research on Zika virus, including finding virus in Brazilian monkeys, dengue antibodies helping Zika virus infection, and brain organoids to study how Zika virus causes microcephaly.
