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.
