Coming down from the buzz of the Oscars, we're taking a look at Christopher Nolan's award-winning film 'Oppenheimer.' It chronicles the life and legacy of J. Robert Oppenheimer, the first director of Los Alamos National Laboratory and the so-called "Father of the Atomic Bomb." The movie does not shy away from science — and neither do we. We talked to current scientists at Los Alamos about the past and present science of nuclear weapons like the atomic bomb.
CrowdScience listener Gregory wants to know what affects the way we see the colours of the world. He was looking at a blue summer sky with a friend and they got to wondering whether they both see the same colour blue. So what does influence our vision of the colours that surround us? Could eye colour have anything to do with it? And can we ever really know if your blue sky is the same as mine?
Caroline Steel comes up with some answers, talking to colour scientists about their research into the multiple factors that enable us to see in multi colours, from the intricate biology of our eye to the changing environment around us.
She also investigates her own colour vision and solves a personal mystery, discovering why the world has always looked a slightly different colour from each eye.

Neuroscientist Nathan Sawtell has spent a lot of time studying the electric elephantnose fish. These fish send and decipher weak electric signals, which Sawtell hopes will eventually help neuroscientists better understand how the brain filters sensory information about the outside world. As Sawtell has studied these electric critters, he's had a lingering question: why do they always seem to organize themselves in a particular orientation. At first, he couldn't figure out why, but a new study released this week in Nature may have an answer: the fish are creating an electrical network larger than any field a single fish can muster alone, and providing collective knowledge about potential dangers in the surrounding water.

Astronomers using the James Webb Space Telescope think they have seen the glow from the first generation of stars after the Big Bang. Newton Kavli Fellow Hannah Übler discusses.
The Anthropocene is meant to mean the latest geological era in which humanity is shaping the rocks and environment of our planet. But an unexpected vote by a commission has declined the idea of making this an official definition. Roland hears from one of its leading proponents, geologist Jan Zalasiewicz, about what happened and why it matters.
And, new research indicates that bumblebees can show each other how to solve puzzles too complex for them to learn on their own. Professor Lars Chittka put these clever insects to the test and found that they could learn through social interaction. How exactly did the experiment work, and what does this mean for our understanding of social insects? Reporter Hannah Fisher visits the bee lab at Queen Mary University in London.
Plus, the subterranean South American snake, or rather snake-like amphibian, that feeds its hatchlings milk from specially evolved glands. Brazilian biologist Carlos Jared explains more about this species’ nurturing behaviour.

As award season reaches its climax in the US, Unexpected Elements holds its own glitzy ceremony.
Which bit of science will win Best Picture? Who will take home the Best Supporting Actor? And will Prof Elaine Chew play us out with her Best Original Music?
The nominations include a particularly noisy tiny fish, a sweating mannequin, and a composition based on a misbehaving heartbeat. All this plus your correspondence and a discussion of how far science infuses the real Academy Awards.
Presented by Marnie Chesterton with Godfred Boafo and Camilla Moto.
Featuring pianist Elaine Chew, Professor of Engineering at Kings College London.
Produced by Alex Mansfield, with Tom Bonnet, Harrison Lewis, Dan Welsh and Katie Tomsett.
The Voyager 1 space probe is the farthest human-made object in space. It launched in 1977 with a golden record on board that carried assorted sounds of our home planet: greetings in many different languages, dogs barking, and the sound of two people kissing, to name but a few examples. The idea with this record was that someday, Voyager 1 might be our emissary to alien life – an audible time capsule of Earth's beings. Since its launch, it also managed to complete missions to Jupiter and Saturn. In 2012, it crossed into interstellar space.
But a few months ago, the probe encountered a problem. "It's an elderly spacecraft," says NPR science correspondent Nell Greenfieldboyce, "and it had some kind of electronic stroke." Greenfieldboyce talks to Short Wave Host Regina G. Barber about the precarious status of Voyager 1 – the glitch threatening its mission, and the increasingly risky measures NASA is taking to try and restore it.

Recently, the US Food and Drug Administration approved a first-of-its-kind cancer therapy to treat aggresive forms of skin cancer. It has us thinking of the long history of cancer. One of the first recorded mentions of cancer appears in an ancient Egyptian text from around 3000 B.C. And although we now know much more about how cancer begins — as a series of mutations in someone's DNA — it's a disease people are still grappling with how to cure cancers today. This episode, cancer epidemiologist Mariana Stern talks about cancer history and treatment today — plus, why some people are more prone to certain cancers and why that might matter for curing them.

Storing your data in ‘the cloud’ might sound like an ethereal, intangible place, but it’s actually a physical location - a data centre. CrowdScience listener Art is worried about how much energy and water data centres are consuming. He’s from Ireland, where data centres are gobbling up almost 20% of the national electricity supply and that’s growing, fast.
So how much energy and water are data centres using globally? And how can they become more sustainable? To answer Art’s question CrowdScience heads to chilly western Norway to visit a data centre hidden deep within a mountain, that’s said to be one of the most efficient in the world. And we hear how a data centre in South Africa is saving water and dealing with crippling power cuts by generating its own renewable energy.
Do we just need to stream less TV and reduce our email inbox? With the help of carbon footprint expert Mike Berners-Lee, we crunch the numbers to find out.

Svein Atle Hagaseth, CEO of Green Mountain data centres in Norway
Mike Berners-Lee, Professor at Lancaster University’s Environment Centre and consultant at Small World Consulting
