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 starts with a modest-sized sunshade in low-E...

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. But as the country continues to invest in expanding coal power, is that target achievable?

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 coi...

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. Do we need to rethink our approach?

Intel has an...

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 ...

The multiverse may be bigger than we thought. The idea that we exist in just one of a massive collection of alternate universes has really captured the public imagination in the last decade. But now Hugh Everett’s 60-year-old “many worlds interpretation”, based on quantum mechanics, has been upgraded.

The northern white rhino is on the brink of extinction but we may be able to save it. Scientists plan to use frozen genes from 12...

Half of the human population undergoes the menstrual cycle for a significant proportion of their lifetimes, yet periods remain a taboo topic in public and private life. And that makes it harder both to prioritise necessary scientific research into conditions like endometriosis and for people to understand the basics of how their bodies work.

Researchers have successfully turned lymph nodes into miniature livers that help filter the blood of mice, pigs and other animals – and now, trials are beginning in humans. If successful, the groundbreaking medical procedure could prove life-saving for thousands of people waiting for liver transplants around the world. So far, no complications have been seen from the procedure, but it will be several months before we know if th...

This is a re-airing of a podcast originally released in March 2021.

From beetle explosions to the deep dark depths of the ocean, this episode is all about escape.

The team discusses the amazing (and sometimes disgusting) way bombardier beetles escape predators.

They explain what it takes for an object to reach escape velocity, celebrating the mathematical mind of Katherine Johnson while they’re at it.

And they explore the daunting real...

As we age our immune systems do too, making us less able to fight infections and more prone to chronic inflammation. But a team of scientists has been able to reverse these effects in mice, rejuvenating their immune systems by targeting their stem cells. But there’s a long road to trying the same thing in humans.

Have you seen the incredible new black hole image? Just a couple of years since the Event Horizon Telescope’s first, ...

Fish you wear like a gas mask, moss that turns a robot sentient and critters that will eat your rash – all these oddities and more cohabit on the planet Vesta, the setting for the animated miniseries Scavengers Reign, where a group of human space travellers must innovate with what they find in the landscape to survive. While all this sounds fantastical, there are many parallels with Earth’s ecosystem and the way we regularly borrow...

Human population growth is coming to an end. The global population is expected to peak between 2060 and 2080, then start falling. Many countries will have much lower birth rates than would be needed to support ageing populations. These demographic projections have major implications for the way our societies function, including immigration and transportation, and what kinds of policies and systems we need. 

Remember Rosie t...

This is a re-airing of a podcast originally released in March 2021.

From the quickest animal in the world to the fastest supercomputer, this episode is all about speed.

Opening with the cries of the peregrine falcon, the team finds out how the bird has evolved to endure flying at more than 200mph.

Then they explain how scientists, starting from Galileo, attempted to measure the speed limit of the universe, the speed of light, and how ...

More than 2 million Palestinians in Gaza face widespread hunger, disease and injury as the war quickly becomes the worst humanitarian crisis in modern memory. Even once the war ends, the devastating physical and emotional health consequences will be felt for many years to come, especially by children. And aid groups like UNICEF and the World Health Organization have no long-term plans to meet the post-war health needs of the po...

There’s no moon like our moon. A celestial body twinned with Earth, the moon guides the tides, stabilises our climate, leads the rhythms of animal behaviour and has long been a source of wonder and awe. 

Our Moon: How Earth's Celestial Companion Transformed the Planet, Guided Evolution, and Made Us Who We Are, is a new book from science journalist Rebecca Boyle. In it she takes an intimate look at our satellite and how it’s inf...

A major step has been made toward bringing woolly mammoths back from extinction – sort of. The company Colossal has the ambitious goal of bringing its first baby mammoth into the world by 2028. And its newest advance, announced this week, is in turning adult Asian elephant cells into stem cells. But it’s still a long way from here to the company’s vision of cold-adapted elephants fighting climate change in the Arctic – or even ...

This is a re-airing of a podcast originally released in February 2021.

Keeping you cosy this week is an episode all about warmth - emotional, physiological and geological.

We have an unexpected start to the show, with bees taking the spotlight, but it turns out these cold-blooded little insects can generate immense warmth when necessary.

The team then takes a much bigger view of warmth, discussing the heat of the planet, and of the ma...

Two decades ago, following the Human Genome Project’s release of a first draft in 2001, genetic testing was set to revolutionise healthcare. “Personalised medicine” would give us better treatments for serious conditions, clear pictures of our risks and individualised healthcare recommendations. But despite all the genetic tests available, that healthcare revolution has not exactly come to fruition. Amid news that genetic testin...

Freezing temperatures, dust storms, radiation, marsquakes – living on Mars right now would be hellish. And getting there remains a multi-year journey. But what if we could make it habitable? Could we one day build settlements on the Red Planet or send human scientists to search for life?

That’s the premise of the TV series For All Mankind, which explores a future where the space race continued after the moon landing and humanity kep...
