Animal senses reveal a wealth of information that humans can't access. Birds can see in ultra violet, and some fish can 'feel' electricity. But how do different species sense time? If you've ever tried to swat flies, you'll know that they seem to have super-powered reactions that let them escape before you can blink. Presenter Geoff Marsh asks whether flies have some sort of super-power to see the world in slow motion. Are they watching your hand come down at what might appear a leisurely pace? Science reveals a window into the minds of different species and their temporal perceptions. Some flies have such fast vision that they can see and react to movement at four times the rate you can, and our vision works at more than six times the speed of one species of deep sea fish. This programme delves into each moment of experience to ask 'what is time, biologically?' When birds have to dodge through forests and catch flies on the wing, or when flies have to avoid birds, it would seem that a faster temporal resolution would be a huge advantage. So what is their sense of time? Geoff meets physicist Carlo Rovelli and asks him to jump outside of physics to answer questions on biology and philosophy. Geoff explores the mind of a bat with Professor Yossi Yovel in Israel, and dissects birdsong at super slow speeds with BBC wildlife sound recordist, Chris Watson. Getting deep into the minds of animals he questions whether our seconds feel like swordfish seconds, or a beetles' or birds' or bats..? Presenter: Geoff Marsh Producer: Rory Galloway

Our senses create the world we experience. But do animals have a ‘sense’ of time, and does that differ between species, or between us and other animals? We know that animal senses reveal a wealth of information that humans can't access. Birds can see in ultra violet, and some fish can 'feel' electricity. So perhaps their sense of time is similar. If you've ever tried to swat flies, you'll know that they seem to have super-powered reactions that let them escape before you can blink.

Science reveals a window into the minds of different species and their temporal perceptions. Some birds have such fast vision that they can see and react to movement at twice the speed you can, and our vision works at more than six times the speed of one species of deep sea fish.

Have you ever been out driving and noticed your mind… wandering? CrowdScience listener Sian Gardiner has. When travelling to visit her parents she has to cross a very large, very obvious bridge. But there are times when she finds herself on the other side with no memory of having gone over it. How is that even possible? Presenter Geoff Marsh buckles up to find out. He travels through the science of how driving becomes second nature, brakes sharply when he realises he’s not necessarily in conscious control at 70mph, and tries to refocus when he discovers why drivers don’t always see things that are staring them in the face. He also asks what’s happening when our mind drifts away from the road, and what can be done to help drivers pay more attention and reduce accidents.

A cacophony of singing and screaming creatures’ accents are explored to answer: Can animals of the same species from different places communicate with each other? Presenter Geoff Marsh tries to identify how different these calls really sound for CrowdScience. From wolves to birds to whales and chimpanzees, most animals use sound to communicate, but if groups in different places vocalise in different ways, they may not be able to communicate with others. CrowdScience questioner, Kitty, sets us on an exploration of the vast and varied world of animal communication with inspiration from her dog Monty.
