Physicists have done the math and there should be as much antimatter as matter — but that hasn't been the case so far. NPR Correspondent Geoff Brumfiel explains what's up with matter's "evil twin," antimatter.

Attributing Australia's bush fires, a major study says man-made climate change was a big driver – making the fires at least 30% worse than they would have been if natural processes were the only factors.

We look at preparations for coronavirus in Africa. Although cases there are currently lower than in much of the rest of the world a major training initiative is taking place to spread awareness amongst medics across the continent.

We ask why Horseshoe bats in particular carry coronaviruses, and find a novel idea for distributing vaccines in places without refrigeration.

And why are we obsessed with crime? Kay from Hamburg, Germany asks as every Sunday evening Germans pile into their local pubs to watch Tatort, a hugely successful crime drama which has been running for 50 years.

Presenter Marnie Chesterton starts with the science and speaks with psychologists to get to the bottom of where this obsession might come from. Have we evolved to have an innate obsession with danger or are we addicted to feeling fear?

Or perhaps the dramatisation of crime fuels our obsession. Producer Caroline Steel visits the film set of BBC crime drama, Line of Duty. Producer Jed Mercurio explains what draws us to crime narratives and the techniques he uses to keep his audience captivated.

But does the way we chose to represent crime in media match up with reality? And what is the impact of this on society and policy?

From currency and commerce, food labels to laboratories, the metric system is the foundation of many science and math fields. To mark our 100th episode (a multiple of 10, which is the basis for the metric system!), we spoke with Elizabeth Benham, Metric Program Coordinator at the National Institute of Standards and Technology, about the presence of the metric system in our everyday lives.

This one doesn't end the way you'd expect. Inspired by the Netflix documentary series "Night On Earth," we learn everything we can about a mouse and scorpion who do battle on the regular — from two scientists who study them: Ashlee Rowe at the University of Oklahoma and Lauren Esposito at the California Academy of Sciences.

If you have Netflix, you can watch the critters clash about 18 minutes into the episode 'Moonlit Plains' here.

Read more about Lauren's work with scorpions here, and Ashlee's work with grasshopper mice here. And you can learn more about grasshopper mouse vocalizations from Northern Arizona University's Bret Pasch here.

Depending on your views, far-right populism can represent a welcome return to the past , or a worrying one. The former, argues sociolinguist Ruth Wodak in this Social Science Bites podcast, is one of the hallmarks of far-right populism – a yearning for an often mythical past where the “true people” were ascendant and comfortable.

She’s termed this blurred look backward retrotopia, “a nostalgia for a past where everything was much better,” whether it was ever real or not.

Wodak, who to be clear finds herself worrying and not welcoming, offers host David Edmonds a recipe for becoming a far-right populist. In her scholarship, she’s identified four ingredients, or dimensions, to the ideology that often underlie populist far-right parties.

The most apparent from the outside is a strong national chauvinism or even nativism. This nativism is very exclusive to a specific set of insiders, who focus on creating “an anti-pluralist country, a country which is allegedly homogeneous, which has one kind of people who all speak the same language, have the same culture, or look the same. [Having] this imaginary ‘true people’ is very important.” is very, very important. Far-right populists decide who belongs and who does not belong to the ‘true people.’”

And just as important is then having a group of outsiders to cast as scapegoats responsible for major problems – making for “an easy narrative for very complex issues.” It’s probably no surprise, then, that “conspiracy theories are part and parcel of the far-right agenda. They are very supportive in constructing who is to blame, etc., for all the complex problems.”

Another ingredient is an anti-elitism that targets elites or ‘the establishment’, i.e. managers, teachers, journalists, intellectuals, liberals or your political opponents; “all the people who allegedly don’t listen to ‘us’ and who have very different interests from ‘the true people’.”

Next comes a focus on law and order (“an agenda of protecting this true people”) enforced through a hierarchal party structure. This top-down structure frequently focuses on a charismatic leader who encapsulates the spirit of the ‘true people’ – and rejects the ‘other.’ “Along with the scapegoat,” Wodak explains, “comes ‘the topos of the savior’ … the leader who will save the true American or the true Austrian or the true British people from those all dangers, they will ‘solve’ the problems, protect the people, and they promise hope.”

The final standard ingredient is endorsing conservative values and perceived cultural touchstones, such as Christianity in Europe.

This recipe matters, of course, thanks to the rise of far-right populist politics across the Americas, Europe and Asia. Wodak herself is Austrian – she’s professor in linguistics at the University of Vienna and emeritus distinguished professor and chair in Discourse Studies at Lancaster University – has seen plenty of recent natural experiments in populism throughout continental Europe.

She cites several reasons for the popularity of far-right populism, including the end of the Cold War and the resultant increase in migration from Eastern Europe into the West. Those migrants, previously seen as refugees from communism who were welcomed and even feted, morphed into unwelcome and fear-inducing interlopers (and despite being white and from Christian cultures). Around the same time, she continues, neo-liberal policies changed labor policies in the West, creating inequalities that the right could build on – just as they did in the pro-business responses to the global financial crisis of 2008 (“saving the banks instead of the people”) and globalization.

In this podcast, Wodak also discusses how right-wing populism makes use of social media, how exploiting “otherness” helps roll over self-interest, what the role of a social scientist is in exploring fraught ideologies, and how someone might counteract malign politics.

Wodak has studied right-wing discourse for years, work that is covered in 2015 book The Politics of Fear: What Right-Wing Populist Discourses Mean, which will see a second edition later this year. At present, she is senior visiting fellow at Vienna’s Institut für die Wissenschaft des Menschen where with  Markus Rheindorf she is examining “repoliticization from below.”
