From Dune to The Three Body Problem, is science fiction having a moment? Attention to the genre, as well as TV and films based on it, seems to have exploded in the past few years. With sci-fi often getting a bad rap, it’s time to ditch the snobbery and celebrate its complexity and diversity. And who better to do this with than New Scientist’s science fiction columnist – and our former editor – Emily H. Wilson?
Wilson is a journalist and author. In 2023 she published Inanna, the first of The Sumerians, a trilogy set in the ancient civilisation of Sumer. The books are an epic, speculative retelling of some of the oldest myths ever recorded.
In this episode, Rowan Hooper speaks to Wilson about the enduring popularity of the genre, and why you should be proud to call yourself a science fiction fan. Plus, the pair share loads of recommendations and explore sci-fi’s many different sub-genres, from climate fiction to cyberpunk.
You can learn more about Emily’s trilogy, The Sumerians, here.

There are signs that aliens might be harnessing the power of stars in our galaxy to fuel their civilisations. Dyson spheres are structures that surround entire stars to absorb their energy. Although these are just hypothetical, researchers have detected hints of their existence. But aliens aren’t the only possible explanation.
Being able to freeze human brain tissue could be a game-changer for medical research. While freezing brains is easy, thawing them out without damaging the tissue is much harder. But now a method involving a cocktail of chemical ingredients seems to have solved the problem.. 
The largest ever ‘ecoacoustic’ survey is being conducted throughout the forests of Costa Rica. Sound recordings of various habitats, from degraded pastures to regenerating forests, are being gathered to assess the biodiversity and health of the country’s ecosystems. Hear some of the amazing soundscapes that have been captured for the survey.
Orchids may share food with their offspring. Lab experiments have shown for the first time that parent orchids may be using fungal pathways – the mycorrhizal network – to send vital sugars to seedlings that cluster around them.
Ancient Egyptians were reliant on the Nile river to transport materials used to build the world famous pyramids. But many of those pyramids are built on inhospitable, arid land, far from the Nile. So how did they get the materials there? Geoscientists may have uncovered an ancient clue.

Galaxies come in only a few shapes, which are all very round looking. You’ve got spirals and you’ve got blobs. Not content with this boring assortment, Leah Crane and Chelsea Whyte want to shake things up a bit.
First up they want to give our own spiral galaxy, the Milky Way, more arms. One, two… eight? As many as possible. But they don’t stop at “octogalaxy”. They also ponder on what it would take to defy the laws of physics and create a giraffe-shaped galaxy.
Aided by Vivian U, an astronomer at UC Irvine, the team discusses whether smashing galaxies together would help in their quest, how shooting black holes into orbit via rail gun may create interesting patterns and whether the galaxy sculpture can be made using dark matter.
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.

Do whales have their own alphabet? We’ve long thought the clicking sounds that sperm whales make is their way of chatting to each other, but those clicks may be even more sophisticated than we realised. After analysing whale recordings, researchers suggest the different click patterns are complex enough to form an alphabet – the closest thing to human communication we’ve yet seen in animals. 
We know very little about dark energy – and it turns out we may know even less than we thought. This mysterious force, which accelerates the expansion of the universe, may be changing in an unexpected way, calling our entire understanding of cosmology into question. This discovery by the Dark Energy Spectroscopic Instrument in Arizona could make room for some exciting new physics.
There’s a bird flu outbreak in the US, spreading through herds of dairy cows in nine states. One dairy worker in Texas has even tested positive, though has also recovered. Underreporting and insufficient testing mean we know very little about how fast the virus is spreading. And as officials warn against drinking raw milk, how worried should we be? 
Quantum batteries, while mostly still theoretical, could make charging your phone or electric car unimaginably fast. Researchers are looking at the quickest way to charge these batteries, harnessing the advantages of quantumness – like charging in two different places at once. 
Plus: Which breeds of cats live the longest; good climate news as renewable energy crowds out gas and coal; why reaching out to long-lost-friends is so hard.

How do we understand the stakes of climate change, and communicate them? As we’re facing the consequences of climate change and our historical inaction as a species, how do we come to terms with the reality and uncertainty of our situation?
In H is for Hope: Climate Change from A to Z, Journalist and Pulitzer Prize-winning author Elizabeth Kolbert breaks things down for us, alphabetically. She dissects the narratives around climate change, from sobering facts about our warming planet, to innovations to fuel our optimism.
In this episode, Kolbert reminds us how dangerous our current situation is, and what we are missing in this fight – including gaps in our understanding of how fast the climate is changing. Plus, the role of narratives in shaping how we decide to act.

Last 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?
