Great for killing, and for research: the lethal fangs of saber-toothed cats

Extinct for close to 10,000 years, the saber-toothed cat, Smilodon fatalis, still inspires passionate debate among palaeontologists. Foremost: how did it use its most distinguishing feature? Playfully animated, The Deadliest Tooth spotlights the US palaeontologist Jack Tseng’s research into Smilodon fatalis, including why he believes its formidable fangs were used for attacking rather than scavenging, and the surprising amount of information palaeontologists can now deduce from just a few fossils, including how saber-toothed cubs might have lived millennia ago.

Why a Jackson Pollock masterpiece became an Australian tabloid sensation

The American abstract expressionist Jackson Pollock (1912-56) is a rare artist whose name, style and influence has grown to reach far beyond the art world. But when the National Gallery of Australia in 1973 bought one of Pollock’s most celebrated works, Blue Poles (1952), for a record-breaking sum of US$2 million, it set off a national controversy over the merits of abstract art, as well as about the painting’s place in Australia’s national collection. This short documentary from the New York City-based filmmaker Alison Chernick recalls the unlikely story of how the Australian government’s landmark purchase divided the nation as well as the art world, became an unlikely tabloid sensation, and ultimately found its place in Australian culture.

Parents have long suspected Pokémon rewires kids’ brains. Now there’s evidence

Since 1996, the wildly popular Pokémon media franchise has encouraged kids to geek out over its cast of now more than 800 fictional species. For Jesse Gomez, a neuroscientist at Princeton University, the impact of Pokémon video games presents a unique research opportunity. Inspired by his own childhood love of the original Pokémon Red and Pokémon Blue, which reward the Game Boy player for registering small differences between eight-bit renderings of the characters, Gomez developed an experiment to interrogate how the brain processes visual information.

While pursuing a PhD at Stanford University, Gomez presented images of Pokémon to a group of adults who had played the games as kids and another group that hadn’t, and captured fMRI brain images of the results. Ultimately, Gomez found that, when processed by childhood Pokémon players, the images lit up a small groove in the temporal lobe that remained mostly inactive in the brains of Pokémon newbies. This short documentary from NPR’s show Science Friday tracks how Gomez’s work could potentially lead to a better understanding of learning disorders such as dyslexia and, more broadly, how clever psychological experiments can be sparked by personal experience.

A project to compose music from everyday life is a joyful jolt of pure creativity

The Serbian multimedia artist Miloš Tomić began his Musical Diaries project by seeking out music in everyday life as a form of ‘therapy’ a few years ago. In doing so, he found small sonic surprises everywhere he travelled – objects transformed into improvised instruments and passersby became part of a grand orchestra. Eventually, the idea snowballed into a series of musical video collages – filmed by Tomić and pieced together with the help of some musician friends – that craft audiovisual compositions from his improvisations and discoveries. One such collage, Annual Music Report, mines melodies from sounds found in and around his Belgrade home. The resulting montage, featuring notable contributions from a singer on the Danube river and Tomić’s son Dren, is a singular jolt of joyful creativity, certain to inspire a toe tap and a smile.

When a decomposing, century-old film becomes a haunting meditation on memory

Created using a decomposing 35mm print of the crime drama The Bells (1926), the experimental short Light Is Calling (2004) depicts a dreamy encounter between a soldier and a mysterious woman. With images that reveal themselves only to distort and disappear into the decaying amber-tinted nitrate, the New York-based filmmaker Bill Morrison – known for his use of found materials – invites viewers to meditate on the fleeting nature of all things physical and emotional, while a minimalistic violin score suffuses the century-old images with a wistful, haunting beauty.
