Researchers at the University of Essex report that butterflies use optical illusions to avoid being caught by predators. The study, published by the university on 30 September 2026, suggests the insects exploit visual tricks in their wing patterns to confuse attackers. It adds to growing evidence that animal survival often relies on manipulating predator perception rather than simple camouflage.

A solar farm in Australia has become a talking point after drivers passing by insisted no sheep were grazing inside, despite 4,200 merinos living among the 755,000 panels. The sheep stand only knee-high, and the tilting rows of panels read as one solid sheet of glass from the road. The farmer who grazes the flock between the panel rows eventually rounded the animals up so people could see them for themselves.

A visual illusion is being used to demonstrate gaps in how today's artificial intelligence systems process images. The finding suggests that machines perceive the trick differently from humans, highlighting limits in current computer vision models. Researchers and science outlets are discussing what this means for the reliability of AI vision systems.

A 2D indie game is drawing attention for how convincingly it simulates a living, moving world seen from a train carriage window. The developer's approach creates the illusion of depth, distance and life beyond the glass, and games outlets are highlighting the technique as a clever example of visual trickery in small-budget game design.

A widely shared optical illusion is being used to demonstrate a surprising gap in how artificial intelligence systems see, mirroring the way the human visual system fills in blind spots. The test shows AI vision models can miss what people perceive, highlighting differences between machine and biological perception and prompting discussion about the limits of current computer vision technology.
