Which came first the volcano or the rain? Volcanic eruptions are known to influence global climate systems, even leading to the cooling of the planet. However local weather conditions can also influence the timing and ferocity of volcanic eruptions. As volcanologist Jenni Barclay explains rainwater can contribute to volcanic instability and even increase the explosiveness of eruptions.

Syria has been experiencing civil war for more than 10 years. Many people have left including many of the country's scientists. We speak with 3 exiled Syrian scientists Shaher Abdullateef, Abdulkader Rashwani, and Abdul Hafez about their current work, which involves working with other academics and students in Syria sometimes remotely and sometimes directly.

New findings from Chile reveal an unknown Tsunami emanating from an earthquake there in the 1700s. Historical records mention other ones, but not this one. Geoscientist Emma Hocking found the evidence in layers of sand.

And we discuss the development of tiny robot-like structures made from frog cells, they can move and build other copies of themselves. Sam Kreigman and Michael Levin explain how.

An NPR analysis shows that since the vaccine rollout, counties that voted heavily for Donald Trump have had nearly three times the COVID mortality rates of those that voted for Joe Biden. That difference appears to be driven by a partisan divide in vaccination rates. As NPR correspondent Geoff Brumfield reports, political polarization and misinformation are driving a significant share of the deaths in the pandemic.

South Africa announced their discovery of the Omicron variant to the world as quickly as they could. The response from many nations was panic and the closure of transport links with southern Africa. Tulio de Oliveira who made the initial announcement and leads South Africa’s Centre for Epidemic Response and Innovation tells us this is now having a negative effect on the country, with cases rising but vital supplies needed to tackle the virus not arriving thanks to the blockade.

Omicron contains many more mutations than previous variants. However scientists have produced models in the past which can help us understand what these mutations do. Rockefeller University virologist Theodora Hatziioannou produced one very similar to Omicron and she tells us why the similarities are cause for concern.

Science sleuth Elisabeth Bik and Mohammad Razai, professor of Primary Care in St George’s University in London have just been awarded the John Maddox Prize for their campaigning investigations in science. Elisabeth is particularly concerned with mistakes, deliberate or accidental in scientific publications, and Mohammad structural racism in approaches to healthcare.

Laura Figueroa from University of Massachusetts in Amhert in the US, has been investigating bees’ digestive systems. Though these are not conventional honey bees, they are Costa Rican vulture bees. They feed on rotting meat, but still produce honey.

And, What makes things sticky? Listener Mitch from the USA began wondering while he was taking down some very sticky wallpaper. Our world would quite literally fall apart without adhesives. They are almost everywhere – in our buildings, in our cars and in our smartphones. But how do they hold things together?

To find out, presenter Marnie Chesterton visits a luthier, Anette Fajardo, who uses animal glues every day in her job making violins. These glues have been used since the ancient Egyptians –but adhesives are much older than that. Marnie speaks to archaeologist Dr Geeske Langejans from Delft University of Technology about prehistoric glues made from birch bark, dated to 200,000 years ago. She goes to see a chemist, Prof Steven Abbott, who helps her understand why anything actually sticks to anything else. And she speaks to physicist Dr Ivan Vera-Marun at the University of Manchester, about the nanotechnologists using adhesion at tiny scales to make materials of the future.

Verbal arts, explains Karin Barber, emeritus professor of African cultural anthropology at the University of Birmingham, are “any form of words that have been composed in order to attract attention or invite interpretation which is intended to be repeatable in some way.” They are, she continues, central to all sorts of social processes, “just as much a part of people’s lives as kinship or economic activities.” In this Social Science Bites podcast, Barber offers a specific case study of the application of the verbal arts by examining in depth some of the genres common in the Yoruba-speaking areas of Western Africa. Barber said there are more than 30 million people who speak Yoruba, with the largest number in southwestern Nigeria, where much of Barber’s own scholarship has taken place. She describes the study of Yoruba as a large field in academe, with “hundreds and hundreds” of Yoruba scholars building it up.

Barber herself grew up in Yorkshire and did her first degree, in English, at Cambridge University. She next studied social anthropology at University College London and after a stint in Uganda was told that if she really wanted to pursue her examination of African theater she should go to Nigeria. Her Ph.D. – based on 37 months of field work studying oral poetic performance in everyday life in a Yoruba town - came from Nigeria’s University of Ifẹ (now Ọbafẹmi Awolọwọ University). Barber then spent the next seven years as a lecturer in the Department of African Languages and Literatures at the University of Ifẹ, where courses were taught in Yoruba.

Barber’s scholarship has resulted in several notable books and monographs. The 1991 monograph I Could Speak Until Tomorrow: Oriki, Women and the Past in a Yoruba Town won the Amaury Talbot Prize for African Anthropology; 2000’s The Generation of Plays: Yoruba Popular Life in Theatre won the Herskovits Award of the African Studies Association;  The Anthropology of Texts, Persons and Publics  from 2007 won the Susanne K. Langer Award of the Media Ecology Association; and 2012’s Print Culture and the First Yoruba Novel won the Paul Hair Prize of the African Studies Association and the Association for the Preservation and Publication of African Historical Sources.

In this interview, she tells host David Edmonds about two particular genres of Yoruba verbal arts: ifa, or divination poetry, and oríkì, translated as praise poetry. “Divination is how people govern and manage their lives,” she explains, “so this poetry is really central to how people analyze what’s happening to them and take steps to make sure that things work out as they wish.”

Praise poetry, “strings and strings of epithets hailing the subject’s qualities,” meanwhile, “celebrates and commemorates and highlights the essential characteristics of a person or god or a family or town or an animal. Somehow it evokes the inner essence, the inner properties, and activates them, galvanizes them.” This genre, she details, has changed over the years, emphasizing wealth in the 19th century but more personal qualities and achievements today. “Changing power dynamics are revealed, not necessarily in what the verbal arts specifically say, but in the way they are formed, in the way they are transmitted, who reads them or who listens to them.”

And so verbal arts matter in a social science context. “All verbal arts are produced in an economic and institutional context. You could ask, why did this new genre appear in this context, this particular moment in history. What caused people to devise this way of commenting on society and formulating ides in this particular way? It’s because of the prevailing interplay of social forces.”

For her work, Barber has received a number of high honors, ranging from a Yoruba chieftaincy title - she is the Iyamoye (“mother who has insights”) of Okuku – to appointment as Commander of the Order of the British Empire in the 2012 and Dame Commander of the Order of the British Empire earlier this year.
