The Kakhovka dam and global food security

The Kakhovka dam and global food security

On Tuesday, the United Nations reported that the breach of the Nova Kakhovka dam on the Dnipro River in Ukraine will impact heavily on global food security, causing a rise in food prices and leaving many without access to clean drinking water. Nine days after the disaster Gaia looks to the future alongside Kira Rudyk, Ukrainian MP who is also leader of the opposition party Golos and Laura Wellesley, senior research fellow in the Environment and Society Programme at Chatham House.Earlier this week the three-year inquiry into COVID began, seeking ‘to examine the UK’s response to and impact of the COVID-19 pandemic and learn lessons for the future.’ Eyes are on the inquiry from many angles. Inside Science looks at what scientists hope to contribute and learn from it, with author and broadcaster Philip Ball.Also, a spike in North Atlantic sea temperatures has sparked concern among scientists. Richard Betts, head of climate impacts at the Met Office, talks through the factors that have coincided to form the anomaly.

An ocean of opportunities

An ocean of opportunities

For World Ocean Day, Gaia Vince finds out how the planet’s seas could help us to generate clean power, capture CO2 and feed the world. Gaia is joined in the studio by science journalist and marine biologist Olive Heffernan. She dives into the controversy regarding the potential of mining in deep oceans and discusses whether the seas could become the location for Industrial Revolution 2.0.We’re used to seeing seaweed wrapped around our sushi rolls but it’s so much more than that. As well as being a tasty addition to what we eat, seaweed plays a vital role in absorbing CO2. Gaia speaks to Vincent Doumeizel, a senior adviser on oceans to the UN Global Compact; he’s also the food programme director at the UK-based charity Lloyd’s Register Foundation. He’s confident that seaweed could enable us to sustainably feed a growing global population in the coming decades.Phytoplankton – microscopic species of algae that exist on the surface of the sea – also absorb huge amounts of carbon from the atmosphere. Sir David King, founder and chair of the Climate Crisis Advisory Group and former chief scientific adviser to the UK Government has the radical idea that artificial whale poo could boost phytoplankton growth, leading to an increase in fish stocks and, consequently, improved biodiversity in the oceans. He tells Gaia about his project and the potential it has for carbon capture.When we think of energy generation from the oceans, we tend to think of offshore technology such as wind turbines. But what about generating electricity using the water itself? Gaia speaks to Eco Wave Power’s Inna Braverman who reveals how her project harnesses the power of the waves by attaching to existing coastal structures such as piers and jetties, to provide a source of clean, renewable energy.

AI and human extinction

AI and human extinction

In the headlines this week eminent tech experts and public figures signed an open letter that read “Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war.”One of the signatories was Geoffrey Hinton, the so-called ‘godfather of AI’. He’s become so concerned about the risks associated with artificial intelligence that he recently decided to quit his job at Google, where he had worked for more than a decade. But are these concerns justified, or is it overblown scaremongering? And should we start prepping for a Terminator-style takeover? To get the answers, presenter Gareth Mitchell is joined by computational linguist Prof Emily M. Bender from the University of Washington along with Dr Stephen Cave, Director at the Leverhulme Centre for the Future of Intelligence (CFI). Next up, we hear from Prof Carl Sayer at UCL, along with Dr Cicely Marshall and Dr Matthew Wilkinson from the University of Cambridge, to dig into the science behind wildflower meadows and whether they can boost biodiversity and even help ease climate change. Finally, have you heard about Balto the sled dog? He was part of a life-saving mission in the 1920s and now he has the chance to be a hero once more. His DNA has been studied by the Zoonomia project, which is using databases of genomes from hundreds of mammals to build a better picture of evolution. This data could then be used help identify those animals that are at the greatest risk of extinction.

The benefits and problems of eDNA

The benefits and problems of eDNA

This week, we hear from the University of Florida’s Dr David Duffy. He heads up a team of researchers who are studying sea turtles. In order to track the animals and their diseases, the scientists devised a method of collecting fragments of DNA from tanks at the university’s turtle hospital, as well as from sand and water in the local environment. While they found plenty of turtle DNA, they were surprised to uncover large amounts of high-quality human eDNA. Duffy tells us all about the study and his surprising findings, but also highlights the ethical problems this could raise. We are then joined by Dr Matt Clark from the Natural History Museum, and Sir Jonathan Montgomery from University College London, to discuss the ins and outs of eDNA – how it can be beneficial for conservation, forensics and healthcare, but could also be problematic from a privacy perspective. Muriel Rabone and Dr Adrian Glover from the Natural History Museum have compiled an extensive checklist of all the species present in the remote Clarion-Clipperton Zone, which is an area twice the size of India, five kilometres deep in the Pacific Ocean. While you might expect this part of the sea to be devoid of life, the organisms that live there are surprisingly diverse, and we still know little about them. But the region is also chock-full of in-demand rare-earth metals. And we are joined by Dr Katie King to talk over some of her favourite science stories of the week, followed up by Helen Keen, who gets the kettle on to reveal more about the surprising physics behind a cup of coffee. Milk and two sugars for us, please. Presenter: Gareth Mitchell Producer: Hannah Fisher Content Producer: Alice Lipscombe-Southwell

Science in the making

Science in the making

The Royal Society is the oldest scientific academy in the world. Since being established in 1660, it has painstakingly archived thousands of papers, letters, manuscripts and illustrations from some of science’s most enquiring minds.In this episode, Victoria Gill takes a trip to the society to pore over some of the most intriguing artefacts within its vaults. While there, she finds out more about the formation of the Royal Society and how science has been shaped over the centuries. Along the way, she considers the role of women in science, and asks whether their contributions have been historically overlooked.She is joined by the Royal Society’s Louisiane Ferlier and Keith Moore, along with Prof Uta Frith, a Royal Society Fellow and psychologist, and Dr Stephen Webster, a senior lecturer in science communication at Imperial College London. As part of its Science in the Making project, the Royal Society is currently digitising all of its collections, for everyone to browse through and enjoy. You can find out more on the Royal Society website.Presenter: Victoria Gill Producers: Harrison Lewis, Hannah Fisher Content Producer: Alice Lipscombe-Southwell

Can we prevent natural disasters?

Can we prevent natural disasters?

Natural disasters such as earthquakes, tsunamis, volcanoes and hurricanes all have the power to cause deadly destruction. One event can lead to another, causing a chain reaction of devastation that can take years to rebuild from. But do all natural events have to turn into a disaster? Is there anything we can do to mitigate their impacts? Gaia Vince speaks to Anastasios Sextos, Professor of Earthquake Engineering at the University of Bristol to find out how we can engineer buildings to withstand earthquakes, and Bruce Malamud, Executive Director of the Institute of Hazard Risk and Resilience at Durham University, to learn how we can build models to forecast the risk of a natural disaster occurring. Lucy Easthope is a leading advisor on emergency planning and disaster recovery and a Professor in Hazard and Risk at Durham University. She joins Gaia in the studio to discuss her experience of being one of the first responders to disasters and how in fact, the way they unfold is more predictable than we might think. Ilan Kelman, Professor of Disasters and Health at UCL, also joins them to discuss the importance of social resilience, long-term planning and effective alert communication in managing and mitigating the aftermath of these events.

70th anniversary of the discovery of DNA’s structure

70th anniversary of the discovery of DNA’s structure

James Watson and Francis Crick, who detailed the double-helix structure of DNA in 1953, are perhaps two of the most iconic scientists of the 20th Century. Yet the story of how they made their incredible discovery is perhaps equally famous, with a notorious narrative suggesting that they only identified the structure after taking the work of Rosalind Franklin and using it without her permission. Now, 70 years after the discovery of DNA’s structure, it is perhaps time to rewrite the tale. New evidence has now been unearthed, in the form of an overlooked news article and an unpublished letter, that shows that Franklin was truly an equal contributor to the discovery, and Watson and Crick were not as malicious as previously assumed. Together with Matthew Cobb of the University of Manchester, Nathaniel Comfort from Johns Hopkins University, and Angela Creager of Princeton University, Gaia Vince discusses this tantalising tale and finds out more about how this discovery could bring a whole new twist to the story of DNA.
