Unexpected Elements

How do you translate the latest science work across the 2000 different languages spoken around the African continent? And have you heard of sky mountain? Africa Day has the Unexpected Elements team taking a deep dive into a range of unexpected stories from across the continent.
The day is celebrated every year to mark the establishment of the African Union in 1963. In the Turkana region of northern Kenya, we learn about a team of geologists who have been studying continental break-up. Researchers think it could be one of the weakest areas of the Earth’s crust. We explore the difficult process of translating scientific papers into the many languages spoken across the continent.
Plus, entomologist Dr Gimo Daniel tells us about the unexpected joys of dung beetles. And we learn how AI and large language models are finding new ways to track conservation and mass animal migrations.
And finally, we explore why bats harbour so many diseases yet seem to be tolerant to things that humans get ill from.

Have you ever wondered what happen to salmon when too much cocaine seeps into their rivers? Inspired by the Enhanced Games, we lookat unexpected areas of performance enhancement. Peptides are making a splash in influencer circles, but what is the science?
Plus, we hear from Prof David Putrino, who is making sure the athletes at the Enhanced Games are staying safe. He shares what we can learn from the Games – and how the data could help develop future medicines.
Also on the show, whether radio waves can enhance your sense of smell, and is an hour at a gallery as beneficial as an hour at the gym?

An outbreak of hantavirus on the MV Hondius cruise ship has us looking at the unexpected science around the disease. First up, why is this outbreak such an unusual occurrence?
Then, what's in a name? We look at how diseases are named, and why the system has sometimes been problematic.
Also, the mysterious case of medicine disappearing from the quarantine tanks at an aquarium. We speak to the expert who solved the puzzle.
All that, plus more fun and strange science, on this week's Unexpected Elements.

Sir David Attenborough is arguably the world’s favourite broadcaster, and this week he’s blowing out the candles on his 100th birthday cake. Inspired by his significant birthday, we decided to uncover the biology behind centenarians. What are Sir David’s secrets?
Speaking of ageing, we then find out about a little jellyfish that never gets old. Could it help us unlock immortality?
Next up, climb aboard as we chat with Dr Nadine Johnston, a marine ecologist who works on the iconic Sir David Attenborough research vessel, as she tells us about the tiny Antarctic animals that could lock up more carbon than the Amazon rainforest.
We then find out about improved landslide prediction in Nepal and how the world has changed in Sir David’s life.
All that, plus many more Unexpected Elements.

The blockade on the strait of Hormuz has led to an unexpected consequence – condom prices are set to increase by up to 30 percent! This has us delving into all things contraception, starting with koala hormone implants, the lengthy process of providing birth control to elephants, and a microplastics mystery.
Then, we investigate the elusive male contraceptive – why is it taking so long to develop, and why has it been so hard to approve? Professor John Amory Md, from UW Medical Centre in Seattle, joins us to explain the past, present and future of this medical research.
Plus, how have Chinese researchers cracked the code on eel breeding, and does the moon’s gravity make us lighter at night?
