Benjamin Thompson, Noah Baker and Elie Dolgin discuss RNA vaccines.
In this episode:   01:16 How RNA vaccines came to prominence 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.
News: Search for better COVID vaccines confounded by existing rollouts
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.

Humans setting up home in outer space has long been the preserve of science fiction. Now, thanks to advances in technology and the backing of billionaires, this dream could actually be realised. But is it more likely to be a nightmare?
Kelly and Zach Weinersmith join us to discuss their new book A City on Mars and some of the medical, environmental and legal roadblocks that may prevent humanity from ultimately settling in space.

00:46 Mysterious methane emission from a cool brown dwarfThe James Webb Space Telescope (JWST) is revealing the makeup of brown dwarfs — strange space objects that blur the line between a planet and a star. And it appears that methane in the atmosphere of one of these objects, named W1935, is emitting infrared radiation. Where the energy comes from is a mystery however, researchers hypothesise that the glow could be caused by an aurora in the object’s atmosphere, perhaps driven by an as-yet unseen moon.

13:07 How working memory worksWorking memory is a fundamental process that allows us to temporarily store important information, such as the name of a person we’ve just met. However distractions can easily interrupt this process, leading to these memories vanishing. By looking at the brain activity of people doing working-memory tasks, a team have now confirmed that working memory requires two brain regions: one to hold a memory as long as you focus on it; and another to control its maintenance by helping you to not get distracted.

00:46 Mapping ‘ghost roads’ in tropical forestsAcross the world, huge numbers of illegal roads have been cut into forests. However, due to their illicit nature, the exact numbers of these roads and their impacts on ecosystems is poorly understood. To address this, researchers have undertaken a huge mapping exercise across the tropical Asia-Pacific region. Their findings reveal over a million kilometers of roads that don’t appear on official maps, and that their construction is a key driver for deforestation.

The 'ghost roads' driving tropical deforestation

Around the world, rates of cancers that typically affect older adults are increasing in those under 50 years old. Models based on global data predict that the number of early-onset cancer cases like these will increase by around 30% between 2019 and 2030.
The most likely contributors — such as rising rates of obesity and early-cancer screening — do not fully account for the increase. To try and understand the reasons behind this trend, many researchers are searching for answers buried in studies that tracked the lives and health of children born half a century ago.

08:07 Bird gestures to say 'after you'A Japanese tit (Parus minor) will flutter its wings to invite their mate to enter the nest first. Use of these sorts of gestures, more complex than simply pointing at an object of interest, were thought to be limited to great apes, suggesting that there are more non-vocal forms of communication to be found in the animal kingdom.

13:34 The carbon cost of home-grown vegResearch have estimated that the carbon footprint of home-grown food and community gardens is six-times greater than conventional, commercial farms. This finding surprised the authors — keen home-growers themselves — who emphasize that their findings can be used to help make urban efforts (which have worthwhile social benefits) more carbon-efficient.
