Focus on Africa - City of Maiduguri submerged in heaviest flooding

Devastating floods caused by a burst dam in northeastern Nigeria have submerged entire residential areas, displacing tens of thousands of people and animals. Authorities say at least thirty people have died. Two hundered prisoners also escaped from the Maiduguri state prison. It's been described as the worst flooding in thirty years, reports our correspondent Azzezat Olaoluwa in Maiduguri.

Also, how the influence of so-called Islamic State in Mali is making things worse for women and girls in the Sahel.

And the long history behind naked protests in Uganda. Three young women who staged a nude protest against corruption in front of the country's parliamentary buildings recently, are facing charges in a court of law.

Unexpected Elements - Ngā Wai Hono i te Pō: The new Māori Kuini

Ngā Wai Hono i te Pō ascends the Māori throne as the new Kuini (Queen), much to the joy of her people, heralding a new age of prominence for the Kiingitanga movement.

We ask whether the new queen may have a biological advantage making her a better fit for leadership, whilst searching for examples of matriarchy in the animal kingdom and analogous human societies.

As is customary, Ngā Wai Hono i te Pō was crowned on the same day as her father’s funeral, thrust into a leadership role during a time of profound grief. We hear from Prof Lucy Selman, expert in palliative and end-of-life care from the University of Bristol, and founder of the Good Grief Festival. She speaks about the physical and emotional manifestations of grief and how it can be processed and overcome, even in the face of immense responsibility.

We remember the legendary voice of the late James Earl Jones, who played the intergalactic monarch, Darth Vader, as Marnie unpicks the science of stuttering.

Unravel a massive jigsaw puzzle, uncover a hidden secret behind Queen’s hit song Don’t Stop Me Now, and delve into the fascinating realm of neuroscience and much more on Unexpected Elements.

Science In Action - A landslide-induced megatsunami in Greenland

Nearly a year ago, the top of a mountain on the Greenland coast broke off and slid a thousand metres down into the Dickson Fjord. The impact created a tsunami that started two-hundred-metres-high and sloshed between the cliffs for nine days, producing a global seismic signal. But it was so remote, only now are the details becoming clear. We hear from Paula Koelemeijer, Wieter Boone and Søren Rysgaard.

The decline of the ancient inhabitants of Rapa Nui was unlikely to have been caused by a self-inflicted population collapse, thereby rejecting a contentious theory of ‘ecological suicide’. Anna-Sapfo Malaspinas of the University of Lausanne discusses her team’s findings which shed light on the population history of the island formerly known as Easter Island - one of the most remote inhabited places in the world, around 3,700 km west of South America and over 1,900 km east of the closest inhabited island.

A newly identified species of wasp that attacks and lays eggs inside an adult fly has been discovered by Logan Moore and colleagues from Mississippi State University. Around 200 species of parasitoid wasps that target the fruit fly have been discovered to date - they lay their eggs in living creatures - all of which have been shown to target their hosts during vulnerable stages, such as when larvae or pupae. Until now, no wasp that attacks and develops inside the adult stage of a fruit fly host has been described.

CrowdScience - What is the voice inside my head?

Many of us experience an inner voice: we silently talk to ourselves as we go about our daily lives. CrowdScience listener Fredrick has been wondering about the science behind this interior dialogue. We hear from psychologists researching our inner voice and discover that it’s something that begins in early childhood. Presenter Caroline Steel meets Russell Hurlburt, a pioneering scientist who devised a method of researching this - and volunteers to monitor her own inner speech to figure out what’s going on in her mind. She discovers that speech is just part of what’s going on in our heads, much of our inner world in fact doesn’t involve language at all but includes images, sensations and feelings. Caroline talks to psychologist Charles Fernyhough, who explains one theory for how we develop an interior dialogue as young children: first speaking out loud to ourselves and then learning to keep that conversation going silently. No one really knows how this evolved, but keeping our thoughts quiet may have been a way of staying safe from predators and enemies. Using MRI scanning, Charles and Russell have peered inside people’s brains to understand this interior voice and found something surprising: inner dialogue appears to have more in common with listening than with speaking.

Caroline also has an encounter with a robot that has been programmed to dialogue with itself. Which leads us to some deep questions: is our inner voice part of what makes us human, and if so, what are the consequences of robots developing this ability? Scientist Arianna Pipitone describes it as a step towards artificial consciousness.
