Accelerating seismic tremors are raising concerns for the thousands of people living atop a volcanic hot spot close to Naples, Italy. Volcanologist Alessandro Pino has been keeping a watchful eye on the developing situation.

We stay in Naples where, almost 2000 years ago, the eruption of Mount Vesuvius buried Pompeii, including thousands of scrolls turned to charcoal by the immense heat. This hasn’t stopped people from trying to read the scrolls, destroying hundreds in the process. Now, computer scientist Brent Seales has deployed AI and papyrologists worldwide to decipher the burnt text.

And from ancient scrolls to rainforest soundscapes, ecologist Zuzana Buřivalová has also been using AI to untangle the vast array of life heard in forests, old and new, as a tool to measure biodiversity.

According to the pop icon Madonna, music makes the people come together. But can we prove that using science?

As Madonna embarks on her greatest hits world tour, the Unexpected Elements team on three continents take some of those hits and examine the science behind them.

Like a Virgin take us on an excursion into parthenogenesis, and the Komodo Dragons that can reproduce without the inconvenience of having to find a mate.

Madonna sung about travelling ‘quicker than a ray of light’, but is that actually possible? We take a very fast trip through the strange world of warp bubbles.

And we Get Into the Groove with the physicist who created a record so tiny it fits into one of the grooves of a normal record.

We also hear about the “find your ancestry” kits that have the capacity to solve so-called cold cases, identifying unknown human remains often decades old.

With the eyes of the world on events in Gaza, we discover how tech can help make sure that any reportage – video or photos – are accurate and not doctored.

All that plus your emails and WhatsApps, and a listener wonders whether fish can drown.

Presented by Marnie Chesterton, with Philistiah Mwatee and Katie Silver Produced by Ben Motley, with Alex Mansfield, Tom Bonnett, Sophie Ormiston and Margaret Sessa Hawkins

Artificial intelligence can code computer programs, draw pictures and even take notes for doctors. Now, researchers are excited about the possibility that AI speeds up the scientific process — from quicker drug design to someday developing new hypotheses. Science correspondent Geoff Brumfiel talks about his visit to one protein lab already seeing promising results.

CrowdScience listener Kristine from Wisconsin in the USA wants to know why herbs and spices taste so good to so many of us. She’s intrigued to know if there's evidence that herbs and spices can keep us healthy.

Anand Jagatia visits the historic naval city of Portsmouth in the UK, where exotic spices from around the world were first brought in from the East Asia more than 600 years ago.

He’s on a journey to find out why many of us think spices are delicious. But are there also nutritional benefits to seasoning our food with them? Anand asks what science or studies are there to show that eating herbs and spices can be beneficial for our health?

Microbiologist Monsi Roman joined NASA in 1989 to help design the International Space Station. As the chief microbiologist for life support systems on the ISS, Roman was tasked with building air and water systems to support crews in space. That meant predicting how microbes would behave and preventing them from disrupting missions. And so, on today's show, host Aaron Scott talks to Roman about microbes in space: the risks they pose and where they might take us in the future of space travel.

Lying atop a network of fault lines, where the Indian and Eurasian tectonic plates meet, Afghanistan is prone to earthquakes. However, the Herat area has not seen an event for almost 1000 years. As such, it was the least likely area to experience the series of devastating earthquakes and aftershocks which are reported to have killed thousands this week. Afghani seismologist Zekaria Shnizai discusses the factors which led to the disaster.

After a couple of delays, NASA’s Psyche mission is due to launch this Friday. It will map Psyche, a metal-rich asteroid orbiting the Sun between Mars and Jupiter. Project leader Lindy Elkins-Tanton's excitement for the project is infectious.

And can deep learning help us predict the next pandemic? Computational Biologist Debora Marks’ new tool, Evescape, can predict the most likely mutations a virus will gain under pressure. This could be a game changer.

How did bedbugs become a global concern? We examine why their unconventional reproduction methods are so successful, how bedbugs and humans even crossed paths in the first place and what public health has to do with nation building.

Also on the show, we look at why there's no human version of dog food, how conspiracy theories take hold, and the legal wranglings over an old Canadian oil pipeline.

Coral reefs in Florida have lost an estimated 90% of their corals in the last 40 years. And this summer, a record hot marine heat wave hit Florida's coral reefs, exacerbating that problem. Scientists are still assessing the damage as water temperatures cool. And one researcher is taking coral survival a step further: Buffing up corals in a "gym" in his lab. Reporter Kate Furby went to South Florida to see the coral reefs up close and talk to the innovative scientists working to save them.

Ever read those Choose Your Own Adventure books of the '80s and '90s? As a kid, mathematician Pamela Harris was hooked on them. Years later she realized how much those books have in common with her field, combinatorics, the branch of math concerned with counting. It, too, depends on thinking through endless, branching possibilities. So, she and several of her students set out to write a scholarly paper in the style of Choose Your Own Adventure books. In this encore episode, Dr. Harris tells host Regina G. Barber all about how the project began, how it gets complicated when you throw in wormholes and clowns, and why math is fundamentally a creative act.
