Life is full of choices, from the mundane (like what to wear today) to the critical (how should we deal with the pandemic?). So how can we make the best decisions? That’s what listener David wants to know.
To investigate, Caroline Steel learns how being smarter doesn’t necessarily make you a good decision maker. She speaks to researchers about the importance of ‘gut feelings’ – and how certain people with no intuition whatsoever can struggle to make choices. She also learns why it’s easier to give advice to other people than to follow it yourself, and how we can work together to make the best decisions in a group.

The opposition leader in Benin, Reckya Madougou, has appeared at the country's Economic Crime and Terrorism Court on charges of financing terrorism.The Ghanaian government has said that from midnight on Sunday all visitors to the country need to be fully vaccinated against coronavirus before being allowed to enter.
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.
At least 38 people have died and scores more have been injured in a fire which tore through a prison in Burundi. At least 600 women and girls have been kidnapped and enslaved in the last three years by militants in Mozambique northern province of Cabo Delgado, a report by Human Rights Watch (HRW) says. US Senator Chris Coons says he advised Ethiopia's PM Abiy Ahmed against waging war on TPLF in Tigray for fear that a 'fracturing conflict' might lead to genocide in Ethiopia.
Nigeria's High Commissioner to the UK has branded as "travel apartheid" the UK's decision to put the West African state on its red list, meaning travellers have to pay to isolate in a quarantine hotel. More than 180,000 people have signed petitions demanding justice after the death of a 12-year-old boarding school pupil in Nigeria.
S2 Ep 24. The world’s most efficient swimmer is the moon jellyfish! It’s the inspiration for a soft underwater robot that is safe enough to use in fragile environments like coral reefs and aquatic archaeological sites. By contracting a ring of muscle, the jellyfish can push water out of their bell-shaped bodies, thrusting them forwards without using much energy at all.

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.

Harriett Gilbert talks to the multi-award-winning Trinidadian-British author Monique Roffey about her enchanting novel The Mermaid of Black Conch, which won the 2020 Costa Book of the Year. Roffey spins the mesmerising tale of a cursed mermaid and the lonely fisherman who falls in love with her.
When American bounty-hunters capture Aycayia from the deep seas off the island of Black Conch, David rescues her and vows to win her trust. With Aycayia in hiding, their love grows as they navigate both the joys and dangers of life on shore. But on an island whose history reaches back to darker times nothing is straightforward as old jealousies and ancient grudges surface amongst the inhabitants.
