Discover the unexpected role of metal-rich rocks in generating oxygen in the deep sea, challenging notions about marine ecosystems and mining practices. Explore new findings on alcohol, revealing that moderate drinking might not be as safe as once thought. Delve into the quest for the elusive element 120 and revolutionary methods in element synthesis. Uncover the troubling impacts of biodegradable plastics on soil health, and marvel at advancements in AI and astrophysics, including insights into a record-breaking cosmic explosion.

Planetary scientist Paul Byrne joins the Dead Planets Society to discuss the potential of burning Uranus for scientific advancement. The hosts explore spectroscopy, composition of ice giants, and the possibility of diamonds on Uranus. They humorously strategize ways to extract diamonds by impacting the planet with other celestial bodies. The conversation delves into the consequences of burning Uranus and invites listeners to suggest other cosmic objects for destruction.

Topics include new cases of bird flu in the US, the possibility of using lasers to propel a spacecraft to Alpha Centauri, concerns over the potential collapse of the AMOC system, redefining planets criteria, and the surprising behavior of sea slugs hunting in packs.

Science journalist Zoë Schlanger discusses the remarkable intelligence and behaviors of plants, from deceiving wasps to shape-shifting vines. The episode challenges assumptions about plant life and suggests rethinking scientific approaches. Topics include plant mimicry, kin recognition, and the ethical implications of understanding plant intelligence.

#258Fancy a bite of woolly mammoth jerky? A beef-jerky-like fossil of this prehistoric creature has been discovered – a metre-long piece of skin still covered in hair. And the most amazing thing is that the entire genome has remained intact, giving more insight into these creatures than ever before. Could this help bring woolly mammoths back to life?There is a way to make butter not from cows, not from vegetable oils or even microbes, but from pure carbon. And if you want a climate friendly way of producing a delicious spreadable fat, this may just be it. A company called Savor is using a process that can convert captured CO2 or natural gas into fatty acids. The origin of life is a huge scientific mystery: how can something so complex emerge from inert and random molecules? Well, Google has created a simulation to figure this out. The company has used computer code to recreate the random ‘primordial soup’ of early Earth, with results that might baffle you. When mammals breastfeed, calcium is stripped from their bones to make the milk, but their bones don’t get significantly weaker. How does that work? Well, a new, bone-strengthening hormone found in mice may have finally solved the long-standing mystery – and could benefit human health.Plus: How our pupils change size with every breath; how cosmic rays could help protect financial markets; and how ancient Denisovan DNA may have helped the people of Papua New Guinea adapt to their environment.Hosts Timothy Revell and Christie Taylor discuss with guests Corryn Wetzel, Madeleine Cuff, Matthew Sparkes and Grace Wade.To read more about these stories, visit newscientist.com.

Black hole astronomer Allison Kirkpatrick discusses putting primordial black holes inside things with the hosts, exploring the consequences on stars, celestial bodies, and even a person's body. The conversation humorously delves into the gravitational pull of black holes and the comical scenarios of tinkering with cosmic objects.

Discoveries of the world's oldest ritual and storytelling, mining nickel with flowers, quantum Wi-Fi advancements. Insights from an Arctic trip on melting glaciers. Carpenter ants' amputation behavior, lunar time zone creation, and eggshells for bone regeneration.

Despite humans having never set foot on Mars, scientists have been working for decades to paint a picture of life on the red planet. With the help of photos and videos from robotic rovers, scientists now know more than ever about its rocky terrain, early history and current climate.Now, experts are painting a fuller picture of the dusty planet by using audio recordings captured by these rovers. Composer David Ibbett has used that data in epic fashion: to create an immersive concert that harnesses the sounds of Mars and transforms them into musical instruments and melodies. In this episode, Ibbett explains to host Bethan Ackerley how ‘Mars Symphony’ includes the real sounds of Mars’ winds, dust devils and seismic rumbles and takes the audience on an interplanetary journey through the past, present and future of the red planet. Still curious?

The ancient Greeks once proposed the Earth was at the centre of our solar system and everything orbited us. We like that idea. Let’s make it happen.But as Dead Planeteers Leah and Chelsea find out, if you bring back geocentrism, Earth would only be king of the universe for a very, very short time – before all hell breaks loose.It starts with enlarging the earth and potentially turning it into a black hole, we then have all the planets hurtling towards us through space, then it ends with a visit from Alpha Centauri. Helping them to work out the science (and suspend the rules of physics now and again), is asteroid researcher and planetary astronomer Andy Rivkin.Dead Planets Society is a podcast that takes outlandish ideas about how to tinker with the cosmos – from punching a hole in a planet to unifying the asteroid belt to destroying the sun – and subjects them to the laws of physics to see how they fare.Your hosts are Leah Crane and Chelsea Whyte.If you have a cosmic object you’d like to figure out how to destroy, email the team at deadplanets@newscientist.com. It may just feature in a later episode. Hosted on Acast. See acast.com/privacy for more information. Learn more about your ad choices. Visit megaphone.fm/adchoices
