Kim Hill talks to virologist Chris Smith about Covid-19 in 2020, in retrospect and right now. What's the situation with global access to vaccines for the new coronavirus, and will the "new variant" emerging in the UK defeat the present vaccine repertoire? Where did this variant come from, what does it tell us about how viruses evolve, and is the UK looking at another lockdown post Christmas? Like this podcast?

Do you have any winter holiday traditions? This month, as we were gearing up for our holidays here at the Naked Scientists, we thought it would be a fun experiment to explore the science behind holiday celebrations around the world with the help of Chunendra Sahu, Cristina Rodriguez, Ljiljana Fruk, and Olgo Loblova - all researchers at the University of Cambridge...

The WHO estimates that up to 650,000 people globally die each year from the flu, and one of the tools in our arsenal against it is the seasonal flu vaccine. Recently there's been a huge breakthrough in the search for a universal flu vaccine, that is one vaccine that would give broad protection from lots of different strains of flu. Just published in the journal Nature Medicine, Eva Higginbotham spoke to one of the scientists behind the work: Lynda Coughlan... Like this podcast? Please help us by supporting the Naked Scientists

Traditionally, when someone says "vaccine", the image of a syringe and needle usually springs to mind. But injections need trained staff to administer them, and they're unpleasant, even for people who are not scared of needles. So vaccines you can inhale sound altogether more attractive. And that's what researchers at Rutgers University in the US have been working on. They've found a particular clutch of chemical compounds that are very good at passing harmlessly through the lungs and entering the bloodstream where they can interact with the immune system. What's exciting is that these... Like this podcast? Please help us by supporting the Naked Scientists

When we nod off we often dream, but many people have reported that, over the course of the pandemic, what they dream about has changed dramatically. It seems to be a real claim, and scientists are studying it. Eva Higginbotham spoke with dream scientist Alejandro Ezquerro-Nassar from the University of Cambridge... Like this podcast?

The AstraZeneca Oxford University Covid-19 vaccine results were announced recently, but something wasn't quite right: it turned out that some people in the trial had received the wrong vaccine dose, although with surprising results.

Recently news was published of an artificial intelligence system which has analysed bits of speech from participants of a long-running study on dementia. These participants were cognitively normal, didn't have signs of dementia, at the time. The system managed to predict the onset of dementia up to 7 years earlier than human doctors. Katie Haylor asked Susan Kohlhass, director of research at Alzheimer's Research UK what she made of the announcement... Like this podcast? Please help us by supporting the Naked Scientists

Let's dive into the depths and consider the octopus. As well as being famous for its 8 arms, and 3 hearts, octopus vision is also impressive: it helps them spy out dinner, among other things. But light isn't always in great supply when you're hunting around on the seabed, so these creatures have a fascinating ability to taste their surroundings and therefore make decisions about what to eat or not, simply by touching things. Now, a paper from scientists at Harvard explains how this touch-taste system actually works on a molecular level. By studying the cells in the suction cups of the... Like this podcast?

As part of their obesity strategy the UK government announced plans to restrict the advertising of unhealthy foods on TV. And in a paper out recently, Oliver Mytton, of Cambridge University, and colleagues have modelled the potential impact of the TV ban on rates of obesity and overweight among children in the UK. Katie Haylor spoke to Oliver. Like this podcast? Please help us by supporting the Naked Scientists
