Topics include hints of alien life using Dyson spheres, freezing human brains for research, ecoacoustic surveys in Costa Rica, orchids sharing food with offspring, and ancient Nile river mystery in pyramid construction.

Astronomer Vivian U joins Leah Crane and Chelsea Whyte to discuss creating unique galaxy shapes like octogalaxies and giraffe galaxies. They explore galaxy collisions, black holes, dark matter, and cosmic events to sculpt galaxies. The podcast delves into galaxy structures, gas density waves, sustainable matter addition, dark matter manipulation, and the potential for reshaping galaxies for communication.

Journalist and Pulitzer Prize-winning author Elizabeth Kolbert discusses the urgency and challenges of climate change in an engaging and informative conversation. Topics include the role of hope in inspiring action, meeting emission reduction targets, technological innovations, navigating uncertainty in climate preparedness, and the reality of climate change impacts. Kolbert's new book 'H is for Hope' is highlighted, along with the importance of narratives in shaping responses to the climate crisis.

#248Last year marked the hottest on record, shattering previous temperature benchmarks across both land and sea. The rapid escalation – seemingly at odds with the expected cooling after coming out of a La Niña cycle – has prompted scientists to question if climate change is accelerating beyond our models' predictions Just eight minutes of anger can significantly impair blood vessel function and potentially increase the risk of a heart attack. A study has looked into the physiological mechanisms of how intense emotions can affect cardiovascular health.GPS jamming continues to increase in European airspace, a concerning trend that has intensified since Russia's 2022 invasion of Ukraine. Now, attacks in Estonia have prompted one airline to completely abandon flights to the city of Tartu. We discuss the implications for civilian and military aviation and the potential need for alternative navigation technologies.Birds do it, bees do it and so do many species of fly – it’s pollination. In fact, migrating flies play an even bigger role in pollination than we thought. These tiny travelers contribute to ecological diversity and resilience by transporting pollen over vast distances.Plus: A newly discovered sensory organ in praying mantises, used specifically for tasting leaves; the possibility of carbon negative cement; and just how thick is the boundary between air and water?Hosts Christie Taylor and Timothy Revell discuss with guests Madeline Cuff, Clare Wilson, Jeremy Hsu, and Michael Le Page.

Join space scientist Chelsea Whyte and astronomer Leah Crane as they discuss their mission to block the Sun from view at all times, recreating the primal fear of an eclipse. From modest sunshades in orbit to moving entire planets, they explore the risks and challenges of creating a constant solar eclipse on Earth. With the help of astronomer Bruce Macintosh, they even call on knitters to aid in creating the largest piece of art ever made. Listen in for outlandish ideas on tinkering with the cosmos, all subject to the laws of physics.

This podcast explores India's climate change challenges and initiatives, animal communication among wolves and gibbons, the creation of self-assembling devices using quantum fluctuations, and the mapping of a 'tree of life' for over 9500 species of flowering plants.

How much faith should we be putting in artificial intelligence? As large language models and generative AI have become increasingly powerful in recent years, their makers are pushing the narrative that AI is a solution to many of the world’s problems.But Meredith Broussard says we’re not there yet, if we even get there at all. Broussard is the author of More than a Glitch: Confronting Race, Gender, and Ability Bias in Tech. She coined the term “technochauvinism,” which speaks to a pro-technology bias humans often have, where we believe technological solutions are superior to anything else. In this episode, she tells New Scientist’s Sophie Bushwick that our trust in AI systems could have devastating consequences.From discriminatory mortgage-approval algorithms, to the racial biases of facial recognition technology, to the misinformation that appears in chatbots like ChatGPT, Broussard explains why there’s no such thing as trustworthy AI. And she discusses the need for greater education about AI, to help us separate reality from marketing.To read about subjects like this and much more, visit newscientist.com. Hosted on Acast.

This podcast explores the challenges of meeting carbon storage targets for climate change, while also discussing Intel's neuromorphic computer technology. It features an experimental musician's journey with tinnitus and the intriguing question of whether birds dream about singing.

How do you destroy a black hole? Turns out they're pretty tough cookies.Kicking off a brand new series of Dead Planets Society, Chelsea Whyte and Leah Crane take on the universe's most powerful adversaries. With the help of their cosmic toolbelt and black hole astronomer Allison Kirkpatrick at the University of Kansas, they test all the destructive ideas they can think of.Whether it’s throwing masses of TNT at it, blasting it with a t-shirt gun full of white holes, loading it up with a multiverse worth of matter, or sending it back in time – they try everything to kill a black hole. Will they succeed?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.
