Animal Intelligence
Chimpanzees can update their decisions based on stronger evidence, much like humans, according to a study published in Science. Researchers at the Ngamba Island Chimpanzee Sanctuary in Uganda found that the animals switched choices when presented with clearer clues about food locations. This flexible reasoning challenges assumptions about animal cognition.

Researchers at Queen Mary University of London have discovered that bumblebees can differentiate between short and long durations of light flashes, akin to recognizing Morse code signals. This ability, previously observed only in humans and select vertebrates, allows the insects to associate specific flash lengths with food rewards. The finding highlights unexpected timing capabilities in tiny insect brains.
