00:48 Bumblebees can teach each other new tricksOne behaviour thought unique to humans is the ability to learn something from your predecessors that you couldn’t figure out on your own. However, researchers believe they have shown bumblebees are also capable of this ‘standing on the shoulders of giants’ approach to learning. Bees that were taught how to complete a puzzle too difficult to solve on their own, were able to share this knowledge with other bees, raising the possibility that this thought-to-be human trait could be widespread amongst animals.

Many ocean-dwelling animals sense their environment using electric pulses, which can help them hunt and avoid predators. Now research shows that the tiny elephantnose fish can increase the range of this sense by combining its pulses with those of other elephantnose fish. This allows them to discriminate and determine the location of different objects at a much greater distance than a single fish is able to. This is the first time a collective electric sense has been seen in animals, which could provide an ‘early-warning system', allowing a group to avoid predators from a greater distance.
