2021 the year of variants

In our first programme of the year, we gathered a group of scientific experts directly involved in analysing the structure and impact of the SARS- Cov-2 coronavirus. There were concerns over the emergence of two new variants, Alfa and Beta, especially whether these variants might spread more quickly or outmanoeuvre the suite of new vaccines that were about to be rolled out. And now with Omicron, the same questions are being asked about this variant’s ability to spread and overcome our defences. We’ve invited the same scientists back to give us their assessment of our journey with Covid 19 over the past year and discuss their findings on Omicron.Featuring: Ravi Gupta Professor of Clinical Microbiology at the University of Cambridge Tulio De Oliveria Professor on Bioinformatics, Stellenbosch University, South Africa Dr. Allie Greaney From the Medical Scientist Training Program at the University of Washington School of Medicine And Professor Jeremy Luban from the Broad Institute of MIT and Harvard Should you wash your eggs? Well, believe it or not, there is quite an international debate about this question from CrowdScience listener Susan. In Canada, where Susan grew up, commercially sold eggs are washed before they reach stores, whereas in the UK where she is now living they are not. So what is best to avoid contamination?It’s one of a number of egg-themed questions that CrowdScience tries to crack in this episode. One of our presenters, Marnie Chesterton, heads over to Susan’s home in London to cook some eggs and explore other egg cooking questions from our listeners, such as what is the science behind frying an egg without it sticking to the pan and why are some boiled eggs harder to shell than others?Meanwhile, this episode’s other presenter, Anand Jagatia, explores questions about eggs after they have hatched. He investigates a case of curious chicken behaviour sent in by listener Laurie, as well as working out how a cuckoo knows it’s a cuckoo when it’s been raised in another bird’s nest.Featuring: Dr. Vincent Guyonnet, Dr. Valérie Lechevalier, Dr. Siobhan Abeyesinghe and Dr. Ros Gloag(Image:Getty Images)
