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...

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...
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...

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...
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...

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...
Did you miss out on the recent total eclipse? Don’t fear, we’ve got the solution. We bring you the constant solar eclipse.
Chelsea Whyte and Leah Crane have decided not to destroy the Sun this time. Instead, they just want to block it from view at all times. But it’s all in the name of good – so everyone gets to experience the same “primal fear” Leah did when she first saw an eclipse...

What does India’s election season mean for climate change? Last year India overtook the European Union as the third largest annual emitter of greenhouse gases. And as voters head to the polls in the middle of an intense heat wave, it’s critical whichever party wins continues to push towards the goal of net zero emissions by 2070...
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...

Our best climate models for helping limit global warming to 1.5oC may have wildly overestimated our chances. To reach this goal, models are relying heavily on geological carbon storage, a technology that removes carbon from the atmosphere and places it underground. But it may not be nearly as effective as models have suggested, making the task of decarbonising much more difficult...
