Take a shimmering, surreal swim with what might be the Earth’s oldest animals

Until recently, mainstream thinking in biology had long held that sponges were the first animal to emerge on the evolutionary tree. But over the past decade, a new wave of research argues that ctenophores, a phylum of sea invertebrates found in saltwater around the world, might be our oldest and most distant relatives. Featuring entrancing camerawork of ctenophores recorded by the US artist Charles Lindsay at Hope Island in British Columbia, Canada, Fieldwork: Comb Jellies offers a close-up look at the translucent creatures that have prompted the tree of life to be redrawn. As the jellies move across the frame, the quick movements of the fused cilia (or ‘comb rows’) they use to propel themselves diffracts the light into a rainbow, giving them an ethereal glow. Combining audio recorded at source with processed sounds from a variety of underwater microphones, Lindsay’s glitchy and immersive sound design gives the impression of a deep-sea swim on an otherworldly planet.

What it’s like to have aphantasia, the inability to visualise images in the mind’s eye

After his mother’s death, Alex Wheeler felt guilty about how quickly he was able to move on from the initial shock, especially when compared with his siblings. His perspective on his emotions would come into clearer view when, by chance, he learned of a newly coined neurological phenomenon known as aphantasia, in which individuals are unable to generate images in their mind’s eye. In the short documentary Out of Mind, Wheeler retells his story and connects with the UK neurologist Adam Zeman, whose pioneering research on aphantasia gave it a name and brought it into public view, and the UK artist Amy Right, who also has aphantasia. Through Wheeler’s story, the UK filmmaker Simon Mulvaney explores the fascinating connections between images and emotions at the brain level.

No, Mozart isn’t a brain hack for babies – here’s how music really affects intelligence

In 1991, a small study conducted at the University of California, Irvine found that young adults received a modest brain boost from listening to Mozart before performing small mental tasks. From this, an exaggerated mythology surrounding what became known as ‘the Mozart effect’ emerged, linking exposure to classical music with heightened intelligence – especially in babies. In this animation, the UK broadcaster and psychologist Claudia Hammond dissects how a mania for this Mozart effect took hold, and what the research on music and intelligence actually says. In doing so, the short video also provides a telling look at how academic studies are often distorted and overstated in the media and in the public imagination.

The rhythms of rural Thailand, where both food and music are sourced from the ground

Thai Country Living is a film with a title that doesn’t leave you wondering. This charming short documentary by the UK filmmakers Ben and Dan Tubby (also known as the Tubby Brothers) takes viewers on a brief journey to the Isaan region, in Thailand’s northeast. The host for the trip, Suman Tapkham, provides the home cooking, with ingredients fresh from his small farm; the music comes via a bamboo instrument known as a khaen, which Tapkham crafts by hand; and the warm conversation is largely made of reflections on his life spent in the country, and his worries that the unique culture there might soon be lost. Through their portrait, the Tubby Brothers capture a slice of Thailand far from the bustle of Bangkok most commonly associated with the country, and, for many viewers, a more than welcome portion of armchair travel.

How sky-high dreams launched one man’s audacious life in homemade rocketry

As the first civilian to successfully launch an amateur rocket into space in 2004, and a holder of a great many rocketry-related world records since the 1960s, Ky Michaelson has truly earned his self-anointed title as ‘The Rocketman’. Following a decorated career as a Hollywood stunt performer and coordinator, Michaelson, now aged 82, is retired from show business and spends most of his time building rockets in his garage. And his audacious spirit hasn’t mellowed with age. These days, he has his sights set on launching the first homemade manned rocket into space. This upbeat documentary portrait by the US-based director Rachel Knoll explores Michaelson’s unconventional path as a high-school dropout turned rocket engineer who wouldn’t let dyslexia stop him from aiming for the sky.
