Diving to 100 metres on a single breath takes more than strong lungs and limbs

The premise of freediving is simple – divers start at the water’s surface using only a single breath to sustain themselves deep into the abyss. But at depths approaching 100 metres, they risk losing consciousness and blacking out. Roughly 40 people die each year during freediving attempts, but the world record holder William Trubridge has trained himself to block out worst-case scenarios during his dives so that he can keep pushing deeper. Nicolas Rossier’s profile of Trubridge, One Breath, is a compelling look at the human impulse to test limits, even in the face of extreme risk.

The 94-year-old Holocaust survivor who makes every Purim costume contest count

‘It’s important to have something that makes you laugh a little bit.’

At 94 years old, Anny Junek has a streak going: she’s the three-time winner of the Purim costume contest at her retirement home in Rehovot in Israel. As the Jewish holiday approaches again, she’s angling for a fourth win. How will she capture the prize? Don’t ask, it’s a surprise! As a young woman, Junek survived the Bergen-Belsen concentration camp, but lost her parents to the gas chambers of Auschwitz. After the trials and tragedies of her early years, Junek’s perseverance and humour have carried her through a life that included raising a family in Mexico before retiring to Israel. Now her indomitable spirit and sense of what makes for a good show have her hatching a new plan for Purim in this charming film by the US-born, Israel-based director Tamir Elterman.

Come ice-fishing in the deep Canadian winter with an all-Indigenous, all-female crew

‘Indigenous labour is never just work. It’s cultural practice, our Indigenous knowledge. It’s how we are in the world,’ says the Cree filmmaker Alexandra Lazarowich, discussing her inspiration for her latest short documentary, Lake. Produced as part of the Five Feminist Minutes initiative of the National Film Board of Canada (NFB), this observational short by an all-female, all-Indigenous crew follows Métis women on an ice-fishing outing at Lesser Slave Lake in central Alberta. The sweep of the landscape, the crunch of ice and snow, and the whipping wind evoke the sublime vastness and frigid temperatures of the deep Canadian winter. Within this frozen world, the women are masters of their craft, punching a hole in the ice, dropping their nets through, and eventually pulling their catch to the surface. A richly crafted testament to Indigenous expertise drawing on the style of verité documentaries of the 1960s and ’70s, the film is also an understated acknowledgement of the challenges that Canada’s Aboriginal peoples face in accessing fishing rights – rights that have long been subject to government encroachment.

Your body is scanned, destroyed, then reproduced. Do ‘you’ live on the copy?

For centuries, philosophers – and more recently, science-fiction writers – have been concocting riffs and variations on a particular thought experiment: if every bit of your body could be perfectly scanned and replicated, in what ways would the replica still be ‘you’? In this interview from the PBS series Closer to Truth, Andy Clark, a professor of philosophy at the University of Edinburgh, dissects a version of this experiment posed by the US philosopher Daniel Dennett, in which a body is scanned, destroyed, and replicated in a distant place. While science hasn’t yet brought us close to putting Dennett’s conundrum to the test, we can still grapple with the intriguing and perhaps troubling metaphysical questions it raises, questions that might become even more material as we careen further into the information age, including: would ‘you’ be dead, or would your sense of self perpetuate in the copy? And, if you were recreated several times, where exactly might you expect to find your embodied sense of self?

This bird-of-paradise in New Guinea sounds like something from another planet

Endemic to the mountain forests of New Guinea, the King of Saxony bird-of-paradise (Pteridophora alberti) is best-known for the flamboyant, mate-attracting efforts of its males. The bird’s courtship displays – which often double as a means of keeping competitors at a comfortable distance – make use of bright yellow breast feathers, wildly waving head plumes and peppy dance manoeuvres capped off with an exceptionally outsized, almost otherworldly bit of squawking. This video from the Cornell Lab of Ornithology provides a rare glimpse into the world of this idiosyncratic little bird, which has proven notoriously difficult to photograph in its rugged natural habitat.
