Forty years ago this January, the Space Shuttle Challenger disintegrated on its way into orbit. All seven astronauts on board were killed.

In the days after the tragedy, the world wanted answers. What really caused the shuttle to explode? And should the launch have been stopped altogether?

For season five of Science Friction, Dr Karl Kruszelnicki and Fiona Pepper investigate how the Challenger disaster unfolded – and what that has meant for space exploration from 1986 to now.

The Challenger Legacy is a five-part series from Science Friction. Episode 1 is out Wednesday 21st January.

In 2018, a Chinese scientist made an announcement that shocked the world — and landed him years in prison.

In a special episode of Artificial Evolution, Health Report reporter Shelby Traynor traces the story of He Jiankui, the researcher who helped to produce genetically edited babies.

His actions invited condemnation from scientists worldwide and opened new fronts of scientific and ethical debate.

Dr Jane Goodall, a pioneer of ground-breaking chimpanzee field research, has died at the age of 91.

Her early work, published in 1963, transformed our understanding of the social and emotional lives of chimpanzees and encouraged a wave of study into primate behaviour.

She later established the Jane Goodall Institute, now one of the world's largest conservation organisations.

In 2022, Natasha Mitchell interviewed Dr Goodall for Science Friction about her life and work.

This episode of Science Friction first aired in May 2022.

Timothy Andrews has lived with a pig kidney in his body for eight months.

That makes him a record breaker — living longer with a gene-edited pig kidney than anyone else in the world so far.

In the final episode of Artificial Evolution, he tells us about his journey, his hopes for making it a year with the transplant, and the challenges he's faced along the way.

With expanded clinical trials into this 'xenotransplantation' around the corner, researchers and advocacy groups argue a future in which animal organs are used in life-saving transplantation procedures for humans is not far off.

So what is the science and history of xenotransplantation? What are the ethical concerns? And what's happening in Australia?

Gene-edited fish are on the market in Japan, and similar foods could soon be on Australian shelves. But will we want to eat them, how affordable will they be, and what do they even taste like?

On this episode of Artificial Evolution, Pete looks at the future of gene editing for consumption, what's on the menu, and whether it’s a sustainable way to feed the world.

Earlier this year, a US biotech company claimed it had brought back a long-extinct species - the dire wolf, which roamed ancient America thousands of years ago.

And the same editing technology that remade dire wolves could also be used to stop Australian species from going extinct.

In episode two of Artificial Evolution, Pete heads to the labs that are safeguarding the genetic material of unique Australian species and working to bring back the thylacine.

And visits the researchers working on quolls to make them immune to cane toad toxins and experimenting with putting alpaca genes into endangered frogs to protect them from a deadly fungal disease.

As this new field of science opens up opportunities to edit endangered species … can and should we act? And do we have our priorities wrong in tackling species loss and climate change?

Artificial Evolution is a four-part series from Science Friction about how gene technologies are changing the world around us.

Last year, 81-year-old rancher Arthur 'Jack' Schubarth was sentenced to six months in prison.

His crime? An elaborate, multi-country conspiracy to smuggle in the tissue of a rare big horn sheep — clone it — and sell the offspring to hunters.

But how did we get to the point where such a scheme could be run out of an elderly rancher's backyard?

In episode one of Artificial Evolution, we trace the story of cloning from Dolly the sheep right through to the present day.

We discover the technology being used to clone horses right here in Australia — and find out whether Barbra Streisand's clones of her pet dog are anything like the original.

In 1996, Dolly the Sheep became the first ever cloned animal. Nearly 30 years later, genetic technology has reshaped the world around us. What exactly has happened, where are we headed, and are we OK about it?

In Artificial Evolution, our latest series of Science Friction, ABC environment reporter Peter de Kruijff follows the story of gene technologies all the way from Dolly right through to the present day.

From the bizarre criminal conspiracy to clone the world's largest sheep, to the lab trying to bring back long-extinct species, and new trials transplanting animal organs into humans — each episode covers how these technologies are reshaping the world around us.

Episode 1 is out Wednesday, September 3.

We’ve all dreamt of lobbing our smartphone into the ocean and going off grid. 

So what happens when you follow through with it?

For our final episode of Brain Rot, we speak to the people who decided they’d had enough. 

From a French village, to Gen Z ‘luddites’ in New York City and a group of parents in regional Victoria, there are clubs, campaigns and even laws dedicated to a smartphone-free life.

But in 2025, how do you pull it off? And is it actually worth it?

Plenty of people will say they are addicted to the internet. But how well-recognised, scientifically, is an addiction ... to your screen?

In episode four of Brain Rot, we dig into how behavioural addictions work.

And we hear from self-described internet addicts about the treatment programs that help them stay “internet sober”.

Brain Rot is a new five part series from the ABC’s Science Friction about how tech is changing our brains, hosted by Ange Lavoipierre.
