PLoS ONE: Extending Body Space in Immersive Virtual Reality: A Very Long Arm Illusion:
â€¦participants experienced ownership over the virtual arm up to three times the length of the real one, and less strongly at four times the length. The illusion did decline, however, with the length of the virtual arm.

Caught in the act: Bats use the sound of copulating flies as a cue for foraging:
The researchers found that the flies rarely fly at night and mostly sit or run on the ceiling. Finding the flies by echolocation is nearly impossible for the bats as the faint insect echo is completely masked by the strong background echo which makes them virtually â€œinvisible.â€ This scenario completely changes when the male flies find a suitable mating partner. The subsequent copulation is a noisy event because males then produce broadband buzzing sounds that can be heard by the bats. Around five per cent of the fly pairs that engage in copulation were attacked and mostly eaten by the batsâ€¦
Bit like teenagers in horror movies, really.
