The mysterious extinction of the dire wolf
00:45 Dire wolf DNA
Dire wolves were huge predators that commonly roamed across North America before disappearing around 13,000 years ago. Despite the existence of a large number of dire wolf fossils, questions remain about why this species went extinct and how they relate to other wolf species. Now, using DNA and protein analysis, researchers are getting a better understanding of what happened to these extinct predators.

13:31 Post-Brexit science
In December, a last minute trade-deal between the UK and EU clarified what the future relationship between the two regions would look like, after Brexit. We discuss the implications of this trade-deal for science funding, the movement of researchers, and data sharing.

01:16 The rise of RNA vaccines
In less than a year, two RNA vaccines against COVID-19 were designed, tested and rolled out across the world. We discuss these vaccines’ pros and cons, how RNA technology lends itself to rapid vaccine development, and what this means for the fight against other diseases.

09:20 The hurdles for trialling new COVID-19 vaccines
Multiple candidates for new COVID-19 vaccines are still being developed, which may offer advantages over the vaccines currently available. However, running placebo-controlled trials of these candidates is becoming increasingly difficult, so researchers are looking for different ways to evaluate them.

14:45 How long will COVID vaccines be effective?
There is much concern around the world about two faster-spreading variants of SARS-CoV-2. We get an update on whether these variants could render vaccines ineffective.
