You may not realise it but scientists are just as creative as artists. Laura is joined by Tamas Zagyva, a research associate at Imperial College London , and Bridget Kennedy , an artist and lecturer in fine art at Newcastle University, to talk about how they find inspiration, what sort of emotions their work evokes, and what sort of skills are required in their respective disciplines. Heart of Gla...

Vitrification – the process of making glass – is used to immobilise nuclear waste and also happens naturally in the earth. Laura talks to Tracey Taylor from the UK’s National Nuclear Laboratory about the glass making process and to Brian O’Driscoll , a geologist from the University of Ottawa in Canada, about natural glass and why researching this material is so important. Heart of Glass is an exhi...

We're part of an exhibition where science becomes art! Heart of Glass is an exhibition at Florence Arts Centre in Egremont, West Cumbria, UK. The exhibition is on 24th March to 30th June and features images taken at a microscopic scale of nuclear waste glass. The exhibition is supported by The University of Manchester and involves The BEAM nuclear and social research network .

It may not be a very well-known discipline but materials science is really important. Laura, Jasmin and Emma discuss how graphene is made, what makes it a wonder material, what it can be used for and how it can contribute to making environmentally friendly products. They also talk about a much more mature material which influenced the second industrial revolution: steel. This alloy might be old te...

There’s a technology boom (!) and loads of buzzwords surround it including I4.0, big data, and digital twin. Laura and Antonia are joined by special guest Matt, from the Nuclear Institute, to talk about what these things really mean and to try and define them. They also talk about how the nuclear industry is starting to embrace these new technologies, ushering a renaissance of nuclear power that b...

To mark our 50th episode we're revisiting the topic of our first ever episode with a fresh perspective. Laura, Antonia, Rwayda and Jasmin talk about how much the climate will change, how we can have confidence in the climate models, and what civil engineers must do to adapt infrastrucutre like roads and buildings to minimise future risks from the changed climate. They also discuss the perception o...

Loads of alternatives to meat are appearing but what's in them and how are they made? Laura, Ellie and Jasmin discuss their preferences, look at how minced beef is made, compare nutritional factors and speculate on what the future might hold. They also ask existential questions like what is meat anyway and when is a sausage not a sausage? Laura did way more research than the team could include in...

Ever wondered what it’s like to work on a documentary? Antonia asks Ellie and Laura about their experiences of working on TV or as a consultant science communicator. They talk about how they got into science communication, what their role was on the various shows they’ve worked on, and how you tell a compelling story.

Some power stations in the UK that originally burned coal have switched to burning wood pellets. These are usually imported and of course, cutting down forests can lead to loss of habitat. Laura, Antonia and Jasmin discuss greenhouse gas emissions from burning wood and coal, talk about responsible forest management, and discuss how important biomass is for the UK's electricity supply. These discus...

The TIGRR lab in Melbourne has recently announced plans to use genetic material from an extinct animal – the thylacine or Tasmanian tiger – to bring this species back while some crime fighting organisations are investing in genetic technology that could bring back the woolly mammoth. Weird right? Antonia, Ellie and Laura discuss extinction, climate change, and habitat loss while also debating whet...

In the last episode Antonia mentioned that some champions of sustainability have been awarded the Nobel Prize. The team got a bit distracted by this so here's the raw, unedited snippet of the conversation that didn't make the final cut for the episode.

It's possibly the most well known prize that a scientist can be awarded! Ellie, Laura, Antonia and Emma disucss how the nominations and awards are made, what the award means and how science has changed since the first Nobel Prizes were awarded over 100 years ago. They also talk about some of their favorite Nobel Prize wining discoveries and whether they would give out extra awards in the future. T...

We see it a lot in films where someone's life splits into two timelines and it features in the Marvel universe, but is the mutiverse real? Laura and Emma T. talk about quantum physics and the various theories that predict the multiverse as well as discussing practical applications of concepts related to physics such as finding probabilities and quantum entanglement. They also talk about some of th...

At least twenty volcanoes are erupting as you read this but for many, it's not something we often think about. Laura, Antonia and Ellie discuss animals that live near volcanoes, what you would need to know to predict a volcanic eruption, how likely one is to erupt and whether we'd like to live near one. Just how does the galapagos land iguana sense that their volcano is about to blow?
