What happens when you take a cursor – and other video-editing tools – on a city walk

Since Instagram launched in 2010, its visual filters have allowed users to alter scenes from their everyday lives with increasing sophistication and processing power. For his short video Outside, the Russian graphic illustrator and motion designer Vladimir Tomin was inspired by Instagram’s use of realtime AI filters to consider what reality-warping technologies might soon be at our fingertips. In a series of clever – and occasionally slightly sinister – vignettes, Tomin playfully manipulates real video footage with digital editing tools to tilt over garbage cans, elevate street markings, and otherwise hint at a visual world that can be endlessly augmented and changed.

Exit, pursued by Death: a young artist and rabble-rouser mines comedy from mortality

In her short documentary Jonah Stands Up, the US director Hannah Engelson profiles her friend Jonah Bascle: a creative, defiant spirit and New Orleans native who is dealing with a terminal heart condition related to his muscular dystrophy. The setup might sound familiar, but the short film and its subject are refreshingly subversive, refusing to fall into tired clichés about confronting disability and illness with bravery. A scrappy and heartfelt DIY production, the film uses animations inspired by Bascle’s artwork, footage of his standup comedy sets, and emotionally raw doctor’s visits to tell his story. Through Engelson’s tribute, Bascle is never presented as an inspirational force, but rather as the many things – a 20something artist, a disability-rights advocate, a rabble-rousing political candidate, a friend – he was in life.

The blob with a superpower: cut a flatworm in four pieces and watch it regenerate four-fold

Planarians are small flatworms that live in wet and humid areas around the globe. Although these creatures are relatively simple, their small, soft bodies possess one of the most amazing secrets in the animal kingdom. Cut a planarian into as many as 279 pieces and, within a few weeks, each bit will regenerate into a full new worm – head, eyes, digestive system and all. This incredible ability raises interesting questions for philosophers, who might wonder which, if any, of these worms is the ‘original’, and for medical researchers, who are hoping to harness the adaptability of planarian’s powerful regenerative stem cells to help regrow tissue, and potentially even limbs, on humans.

Dance seems to be the ultimate frivolity. How did it become a human necessity?

Every culture dances. Moving our bodies to music is ubiquitous throughout human history and across the globe. So why is this ostensibly frivolous act so fundamental to being human? The answer, it seems, is in our need for social cohesion – that vital glue that keeps societies from breaking apart despite interpersonal differences. The French sociologist Émile Durkheim (1858-1917) theorised that ‘collective effervescence’ – moments in which people come together in some form of unifying, excitement-inducing activity – is at the root of what holds groups together. More recently, Bronwyn Tarr, an evolutionary biologist and psychologist at the University of Oxford who is also a dancer, has researched the evolutionary and neurological underpinnings of our innate tendency to bust a move. Drawing on the work of both Durkheim and Tarr, this Aeon Original video explores that unifying feeling of group ‘electricity’ that lifts us up when we’re enthralled by our favourite sports teams, participating in religious rituals, entranced by music – and, yes, dancing the night away.

Surgeons with chainsaws – the breathtaking craft of logging on a Swiss mountainside

In most of the world, logging is now largely the work of massive machinery. But in the steeply sloped woods above Lake Ägeri in Switzerland, a combination of chainsaws, jacks, muscles and gravity is still the most effective means of bringing down trees for lumber. Once every four years, skilled loggers travel to the area to collect mature trees in a sustainable harvesting tradition that, in turn, allows saplings to take in sunlight and flourish. After felling the trees at careful angles, the workers send them careening through the woods with spectacular speed and force until they reach the water below with a satisfying splash. From there, the timber is floated downriver into town. The loggers’ confident expertise masks the immense dangers of the job, which could easily turn deadly in an instant. With stunning cinematography, Ins holz (In the woods) offers a rare look at this nearly extinct practice and the culture that surrounds it, making for a deeply visceral and visually stunning celebration of a hard day’s work.
