Christopher Nolan's new film 'Oppenheimer' chronicles the life and legacy of J. Robert Oppenheimer, the first director of Los Alamos National Laboratory and 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.

For the third year running, Iceland’s Reykjanes peninsula is experiencing another spectacular volcanic eruption. Volcanologist Evgenia Ilyinskaya has been out in Iceland witnessing the sight and getting samples of the noxious fumes.

Across the rest of the Northern Hemisphere heat domes persist, bringing extreme weather ranging from wildfires to tornadoes. We keep on seeing that this year “is the warmest in 120,000 years”. But what does that mean? Two paleoclimatologists, Bette Otto-Bliesner and Jessica Tierney tell us more.

And we’re going deep. Deep into the brain that is, with a newly-developed probe which is finer than a baby’s hair. Dr Anqi Zhang of Stanford University explains her delicate technology.

Finally, new research suggests that SARS-CoV-2 could have arisen in the wild no more than four years ago, a mishmash of other viral genomes. Bioinformatician Jonathan Pekar discusses his new paper.

Unexpected Elements looks for the science behind the news, and this week the news is glittery and pink with the release of the Barbie movie.

The movie has very pink aesthetic, so we get philosophical about the colour pink – does it actually exist and if so, how come it isn’t in the rainbow?

We also discover how this iconic doll has performed some actual valuable science, helping cryogenic researchers design space suit technology to help future missions to the moon.

In Ask the Unexpected this week we’ve got dog science as we answer the age old joke: how does my dog smell? Terrible, obviously, but it also depends on something called the vomeronasal organ..

And there are newcomers in Germany and they’re troublemakers. We hear how an unpleasant mosquito borne virus has arrived in northern Europe and consider whether climate change might be to blame.

All that plus your emails and WhatsApps, language pedantry and an ewaste dating service.

Presented by Marnie Chesterton Produced by Ben Motley, with Margaret Sessa-Hawkins, Alex Mansfield and Sophie Ormiston

For people with endometriosis—a mysterious disease where endometrial tissue grows outside of the uterus—medical visits can be especially frustrating. It takes some patients years (on average, ten years) to get a diagnosis and treatment options are limited. There are currently no cures. One researcher, Dr. Kate Lawrenson, is trying to change that. She and her team of researchers have created a cellular atlas of the disease and hope this cell-by-cell approach will open up doors for faster diagnosis options and better ways of managing it. In the meantime, she hopes that more people will learn about the disease in the first place.

Trash from humans is constantly spilling into the ocean — so much so that there are five gigantic garbage patches in the seas. They hang out at the nexus of the world's ocean currents, changing shape with the waves. The largest is the Great Pacific Garbage Patch. These areas were long thought to have been uninhabited, the plastics and fishing gear too harmful to marine life. But researchers have recently uncovered a whole ecosystem of life in this largest collection of trash. Today, with the help of marine biologist Fiona Chong, we meet the tiny marine life that calls this place home.

Why are some people left-handed? Why are some people right-footed? Why do some write with their right and throw a ball with their left? What does this all have to do with our brains? Why is it hard for some people to tell left from right? And what about animals? Can they be left-flippered, or finned, or southpawed? That's what a few CrowdScience listeners want to know, and we've got an expert panel on left, right and everything in between to help answer your questions.

From genetics to culture, host Caroline Steel works to unpack what's known and what's still unknown about handedness.

David Carey from Bangor University helps Caroline better understand her own mixed-handedness through a series of simple tests and shares some insights into what role handedness (and footedness) plays in the world of sports. Neuropsychologist Marietta Papadatou-Pastou from National and Kapodistrian University of Athens helps break down the numbers on left v. right-handedness and its cultural influences. To better understand the genetics and evolution of handedness, we hear from Sebastian Ocklenburg from Medical School Hamburg, who has investigated the phenomenon in other species.

Throughout the show, Caroline tries to understand why handedness exists in the first place and why our species is so biased to the right. She tries to answer listener Barb’s question as to why ambidexterity isn’t more ubiquitous, and it leads to some brainy tangents. We also hear questions from listeners Scotia and Roland, and travel to India with BBC reporter Chhavi Sachdev to hear how cultural norms are not in favour of lefties.

Science in the headlines: An amazingly preserved sea squirt fossil that could tell us something about human evolution, a new effort to fight malaria by genetically modifying mosquitos and why archeologists are rethinking a discovery about a Copper-age leader. All Things Considered host Adrian Florido nerds-out on those stories with Short Wave host Regina G. Barber and science correspondent Geoff Brumfiel.

As extreme heat returns to much of the world we hear the impact of last year’s heatwaves in Europe, where 62,000 people are estimated to have died. Joan Ballester, Associate Research Professor at Barcelona Institute for Global Health, discusses the figures from his latest paper and his concerns for the future.

This week the European Court of Human Rights ruled in favour of middle-distance runner and Olympic champion Caster Semenya in a case related to testosterone levels in female athletes. Marnie Chesterton speaks to developmental biologist Dr Emma Hilton about what causes differences in sexual development and the impact they can have.

Also, Kew Gardens is going digital. Millions of specimens are being made available to the world for the first time in an enormous digitisation project. Ella Hubber goes behind the scenes at Kew to see some of the precious specimens.

Finally, the Indonesian government has banned a group of foreign scientists from conducting conservation research. Bill Laurance, Research Professor at James Cook University, talks to Science in Action about keeping politics out of conservation science.

As Nato meets, we look at what science says about consensus decision-making, whether the universe is left-handed, and what chemistry can tell us about our ancient past.

Also, we examine windfarms potentially blocking reindeer herding, our quest for the coolest science in the world continues with Beth the bee queen, and Caroline contemplates the long road that got us to a malaria vaccine.

Canada is having its worst fire season in modern history. The fires have burnt more than 20 million acres, casting hazardous smoke over parts of the U.S. and stretching Canadian firefighting resources thin. Public officials and many news headlines have declared the fires as "unprecedented," and in the modern-sense they are. But NPR climate correspondent Nate Rott has been talking to researchers who focus on the history of wildfire in Canada's boreal forests and they say the situation is not without precedent.
