Another destructive fire season has Western states searching for ways to prevent it. As climate correspondent Lauren Sommer reports, some answers might lie in the Southeastern U.S. The region leads the country in setting controlled fires — burns to clear vegetation that becomes the fuel for extreme fires.

Manufacturers can expect to face unforeseen hurdles when they begin to mass-produce a brand new pharmaceutical product, and in a pandemic, there are bound to be supply chain problems as well. But in late 2020, Pfizer was delivering fewer doses than the government expected and then-federal officials told NPR they did not know why.

Molefi Kete Asante, the chair of the Department of African American Studies at Philadelphia’s Temple University, has long been at the forefront of developing the academic discipline of  Black studies and in founding the theory of Afrocentrism, “the centering of African people in their own stories.” In this Social Science Bites podcast, Asante offers an insiders view of the growth of the Afrocentric paradigm, from the founding of the Journal of Black Studies a half century ago to the debates over critical race theory today.

“Afrocentricity,” Asante tells interviewer David Edmonds, “is a paradigm, an orientation toward data, a perspective, that says that African people are subjects, rather than objects, and that in order to understand narratives of African history, culture, social institutions, you must allow Africans to see themselves as actors rather than on the margins of Europe, or the margins of the Arab culture, or the margins of Asian culture.”

While that might seem a mild prescription, it’s one that has been often ignored. Asante offers the example that the waterfalls between Zimbabwe and Zambia had a name (Mosi-oa-Tunya for one) before European explorer David Livingstone arrived and dubbed them Victoria Falls.

“Livingstone is operating in the midst of hundreds of thousands of African people – kings and queens and royal people – yet the story of southern Africa turns on David Livingstone. The Afrocentrist says that’s nonsense; here's a white guy in the midst of Africa and that you turn the history of Southern Africa on him does not make any sense to us.”

Asante then details some of his own efforts in centering the stories of Africa and the African diaspora in their own narratives, including the founding of the first academic journal focused on doing so. He details how as a PhD student in 1969, he and Robert Singleton started the effort to create the Journal of Black Studies as a forum for the nascent academic discipline. (The story sees SAGE Publishing, the parent of Social Science Space, and its founder Sara Miller McCune taking an important role as the one publisher that embraced Asante’s proposal in 1970.)

“The journal survives,” he explains 50 years later, “based on its relevance to contemporary as well as historical experiences.”

At the time the journal was founded, Asante directed the University of California Los Angeles’ Center for Afro American Studies from 1969 to 1973. He chaired the Communication Department at State University of New York-Buffalo from 1973 to 1980. After two years training journalists in Zimbabwe, he became chair of the African American Studies Program at Temple University where he created the first Ph.D. Program in African American Studies in 1987. He has written prodigiously, publishing more than 75 books, ranging from poetry on Afrocentric themes to high school and university texts to the Encyclopedia of Black Studies.

The universe is so much bigger than what people can see, and astrophysicist Priyamvada Natarajan is trying to figure out that which we can not see. Producer Rebecca Ramirez talks with Priya and reports on the theory about some of the secret scaffolding of the universe: dark matter.

Our connection to the night sky spans cultures and millennia: observing the stars and planets helped our ancestors navigate the world, tell stories about the constellations, and understand our place in the universe. But these days, for the vast majority of us, seeing the stars is getting harder. 80% of people live under light polluted skies, and in many cities you’re lucky to see a handful of stars at night.

This state of affairs is bothering CrowdScience listener and keen stargazer Mo from Salt Lake City in the USA, who wonders if there’s anything we can do about light pollution. Of course, we could simply turn out all the lights, but that’s unrealistic. So what are smarter ways of lighting our communities to preserve our view of the cosmos?

Increasingly worried by the effect of artificial lighting on the ability to observe stars, astronomer Dr Jason Pun set up a series of monitoring stations to continuously measure ‘sky glow’. By comparing sky glow across the world, he wants to figure out which approaches work best.

One community taking an active approach is the South Downs National Park in South East England, one of a number of Dark Sky Reserves around the word. We visit the park and speak to the Dark Skies Officer there, to find out how people are coming together to turn down their lights and keep the night dark.

And it’s not just stargazing that’s threatened by light pollution. Artificial light at night disrupts the circadian rhythms of wildlife. We visit a project in rural Germany looking into the benefits of dark-sky-friendly lighting on insect populations there.

With contributions from Dr Jason Pun, Paulina Villalobos, Dan Oakley, Doug Jones, Dr Sibylle Schroer and Sophia Dehn.

When hurricane Ida struck the coast of Louisiana last weekend, almost to the day that Katrina did 16 years ago, comparisons between the two events were soon to follow. As the latest storm continues to wreak havoc and death further north in the US, Suzana Camargo of Columbia university talks to Roland Pease about the similarities and differences, the better forecasting available now, and the grim reality that climate change suggests for this and future hurricane seasons.

A couple of weeks ago, Science in Action looked at the carbon accounting of Blue Hydrogen (hydrogen manufactured from fossil fuels). Listener Nick Arndt got in touch to say we were wrong when we stated that hydrogen can’t be piped out of the ground from natural sources. His company, Sisprobe, plans to use its passive seismic prospecting technology to work with an international consortium that aims to unlock a new “hydrogen Rush” – commercialising what they suspect to be a near-ubiquitous source of genuinely carbon-free fuel - to supply the world economy of the near future. Viacheslav Zgonnik - CEO of start-up Natural Hydrogen Energy LLC - has been working on hydrogen for 10 years, has written a recent review of the science, and tells Roland about current and future studies into finding the best way to tap this simplest of molecules before it escapes into space.

In Chile, the recent megadrought has led to fears that hydroelectric damns may become so drained that power-outs may occur in the coming months. This will not help Chile to achieve its target of carbon-neutrality by 2050. Apt, then, that a new Concentrated Solar Power plant (CSP) is now up and running in the north of the country. Reporter Jane Chambers has been to visit Cerro Dominador – the spectacular new array of 10,600 mirrors that focus sunshine onto a molten salt target, heating it up to 560C, and generating up to 210 MW electricity.

Meanwhile archaeologists have been doing a molecular analysis of a protein found to survive in the bones of unfortunate victims of the mount Vesuvius eruption that destroyed Pompeii. Despite the searing heat that killed inhabitants of nearby Herculaneum, Oliver Criag of York University has been able to examine the different isotopes in amino acids still recoverable from their bones to help identify what sorts of things these people ate during their tragically foreshortened lifetimes. A whole lot of cereals generally, but more interestingly, the men tended to eat more fish while the women seem to have consumed more meat and dairy.

Maddie and Emily get super nerdy one last time as they dive into the incredible world of nudibranchs. Not only are these sea slugs eye-catching for their colors, some of them have evolved to "steal" abilities from other organisms — from the power of photosynthesis to the stinging cells of their venomous predators. These sea slugs are going to blow your mind!
