Eritrea's President Isaias Afwerki has said that the United States supported the Tigray People's Liberation Front or TPLF in its 2-year war with the Government in Addis. In a long interview, he claimed the US pressed the peace deal to prevent the Tigrayans being defeated.
Also, Ghanaian pensioners protest outside the Ministry of Finance offices, saying the Government shouldn't make them destitute.
Plus, we hear why countries on the continent are now THE destination for African tourists who prefer the attractions closer to home than elsewhere.
Those stories and more in this podcast with Bola Mosuro.
In the early hours of Monday, a powerful earthquake hit Kahramanmaras in Turkey. Nine hours later another struck. When this edition of Science in Action first aired, 19,000 people were reported to have died, but that number was expected to rise.
Back in 2016, Professor Asli Garagon and her colleagues accurately predicted that an earthquake of this size was coming. Using GPS, they were monitoring the East Anatolian fault to calculate energy building between the plates. With such accurate insight could Turkey have been better prepared?
Ross Stein, seismologist and founder of Temblor, a Californian consultancy that specialises in assessing hazard risk, estimates the plates moved at 5,000 mph. The movement of the plates may have built up pressure in other parts of the country.
And finally, Tiziana Rossetto, a civil engineer at University College London, knows better than most that earthquakes do not kill, buildings do. She tells Roland how the combination of earthquakes and subsequent aftershocks appear to have even destroyed buildings that were purposely built to withstand them.
Also, Why does the thought of giving a talk to an audience fill so many of us with sheer terror? Marnie Chesterton investigates for listener Nhial, who has seen his fellow students in Morocco become panic stricken at the prospect and wants to know the reason for our anxiety. According to one study, 77 per cent of us share that fear.
Marnie finds out about the relationship between stress, our brains and our voices from research associate Dr Maria Dietrich at the University Hospital, Bonn University. She talks to Nhial’s tutor, Professor Taoufik Jaafari, at Hassan II University of Casablanca about the challenges facing his students. And she visits the National Theatre in London to get some expert training from Jeannette Nelson, head of voice, who works with some of the world’s leading actors.
Could there be an evolutionary explanation for the purpose of public speaking? Is it something we actually need to be good at? Marnie asks evolutionary psychologist Professor Robin Dunbar at Oxford University and gets some surprising answers. She meets psychologist Dr Preethi Premkumar at London South Bank University, who has developed virtual reality therapy with colleagues at Nottingham Trent University, and tries out the treatment herself.

Pull on an extra layer and stay toasty whilst Science in Action braces for a deep freeze. Whilst we know plenty about the ice on the Earth’s poles, Roland is on a chilling journey to see what can be found in deep space.
Professor Christoph Salzmann and Professor Andrea Sella at University College London have produced a new phase of ice. Roland heads to the laboratory to see how the usual crystalline ice, found in ice cubes and icebergs, can be broken down and arranged into a new structure.
The James Webb Space Telescope has detected the coldest ices to date, deep within a molecular cloud in outer space. Professor Melissa McClure describes how these clouds harbour a variety of different molecules potentially capable of forming the basic building blocks for life.
From the edges of the universe to something a little closer to home, Professor Geoff Collins and colleagues have discovered odd tectonic plate activity on icy Europa, one of Jupiter’s moons.
We generate a huge amount of noise, whether it’s our rumbling roads, pumping parties, or talkative tourists. And the topic of noise also generates a lot of questions from our listeners. In this episode we explore three of them, with the help of acoustic scientist Kurt Fristrup and neuropsychologist Catherine Loveday.
Listener Dominique finds it hard to experience even one minute of a natural soundscape without some intrusion of human-made noise. He wonders how noise pollution is affecting both the natural world and us humans. We discuss just how noisy our modern world is, and visit a National Park in California to hear how they’re encouraging more peace and quiet there.
Meanwhile Michelle, having witnessed her husband wince in pain at the sound of squeaking takeaway boxes, asks why certain noises are particularly unpleasant or even painful to some people.
And finally, Jennifer has a sonic mystery for us to solve: why does the time of day make such a difference to the distant noises reaching her remote home?
Driving too fast through Israel’s Negev desert in his SUV after a long day in the hospital, Dr Eitan Green accidentally hits a lone Eritrean man on the empty moonlit road, killing him instantly.
Panic stricken he drives off instead of calling for help and confessing what he’s done. A decision that will change the course of his life irrevocably because the dead man’s wife, the elegant, enigmatic Sikrit, knows what happened. In atonement for his crime Sikrit insists the doctor start treating Eritrean refugees after his hospital dayshifts at clandestine makeshift hospitals in the desert.
A nail-biting and morally devastating drama of guilt, racism, shame and desire which stares unflinchingly at the darkness inside us all, and asks the reader: what would you have done?

And a theory for the origin of life that may surprise you. Professor Philipp Holliger is trying to uncover whether ice played a role in our creation, acting as a medium capable of concentrating molecules and promoting the chemical reactions required for the generation of RNA, essential for cell protein production.

An outbreak of pathogenic bird flu, H5N1, in a Spanish mink farm could be a cause for concern. Some experts fear the virus may now spill over to other mammals without strict surveillance. Marion Koopmans, professor of virology at Erasmus Medical Centre, talks Roland through the potential risks.
India’s caste system affects all aspects of society, but how does the hierarchy influence representation of marginalised groups in academia? Science journalist Ankur Paliwal believes that, despite efforts to combat discrimination, not enough is being done, and he has the data to prove it.
Imagine a robot... Is it hard, metallic and humanoid? Professor Carmel Majidi from Carnegie Mellon University and his colleagues are thinking outside the robotics box. Their new material, magnetic in nature, can shift between solid and liquid states. It’s even capable of breaking out of robotic jail...
From Lawrence of Arabia to Star Wars via tales of intrepid adventurers traversing lonely sandswept landscapes, deserts have always had a powerful pull on the popular imagination.
But if a desert is full of sand, where did all that sand come from in the first place? That’s what CrowdScience listener Andy wants to know, so presenter Caroline Steel heads off into the dunes to try and find out.
Along the way she’ll be wondering what a desert is anyway and whether it’s always sandy, as well as tracing the flow of material across the huge, ever-shifting sand seas of the Sahara.
From deserts fed by sand from mountains thousands of kilometres away, to dunes migrating across the entire continent of Africa, we’ll discover how sand has just the right properties to be carried along by the wind.
We’ll also explore how the sand in every desert has a unique fingerprint, and find out how fish bones in the Sahara tell the story of its lush, green past.
