The whole world mourned the passing of music legend Tina Turner last year, perhaps none more so than Australians, who have always had a special fondness for her. That's not just because of her star turn as Aunty Entity in 1985's Mad Max Beyond Thunderdome or her stint as the face of Australia's rugby league.

Australians of all ages have also been performing a line dance called the "Nutbush" at weddings and social events to Turner's hit single (with then-husband Ike Turner) "Nutbush City Limits." Turner herself never performed the dance, but when she died, there was a flood of viral TikTok videos of people performing the Nutbush in her honor—including members of the US Embassy in Canberra, who had clearly just learned it for the occasion. Dancers at the 2023 Mundi Mundi Bash in a remote corner of New South Wales set a world record with 6,594 dancers performing the Nutbush at the same time.

The exact origin of the dance remains unknown, but researchers at the University of South Australia think they understand how the Nutbush became so ubiquitous in Australia, according to a paper published in the journal Continuum. “What we seem to know is that there was a committee in the New South Wales education department that devised the idea of the Nutbush,” co-author Jon Stratton told the Guardian. “Whether they devised the dance itself, we don’t really know. But what’s interesting is that nobody has come forward.”

Elon Musk, back in October 2021, tweeted that “humans drive with eyes and biological neural nets, so cameras and silicon neural nets are only way to achieve generalized solution to self-driving.” The problem with his logic has been that human eyes are way better than RGB cameras at detecting fast-moving objects and estimating distances. Our brains have also surpassed all artificial neural nets by a wide margin at general processing of visual inputs.

To bridge this gap, a team of scientists at the University of Zurich developed a new automotive object-detection system that brings digital camera performance that’s much closer to human eyes. “Unofficial sources say Tesla uses multiple Sony IMX490 cameras with 5.4-megapixel resolution that [capture] up to 45 frames per second, which translates to perceptual latency of 22 milliseconds. Comparing [these] cameras alone to our solution, we already see a 100-fold reduction in perceptual latency,” says Daniel Gehrig, a researcher at the University of Zurich and lead author of the study.

Replicating human vision

When a pedestrian suddenly jumps in front of your car, multiple things have to happen before a driver-assistance system initiates emergency braking. First, the pedestrian must be captured in images taken by a camera. The time this takes is called perceptual latency—it’s a delay between the existence of a visual stimuli and its appearance in the readout from a sensor. Then, the readout needs to get to a processing unit, which adds a network latency of around 4 milliseconds.
