Today, the general view about the role emotions play in our lives has radically evolved, and the importance of emotions throughout the animal kingdom has finally been recognised. Charles Darwin already intuited 150 years ago when he wrote that emotions are “a universal means of communication” across the animal kingdom. As for us humans, we now know that emotions literally shape every aspect of our lives, including things as unique to our species as rationality and morality.

Who hasn't felt the temptation to fling a lengthy manual into the bin, or just drive on instead of asking for directions? After all, following instructions is often tiresome, and we can just figure it out on our own… Or can we? A study published today (May 19th) in the scientific journal Nature Human Behaviour challenges prevalent theories about our capacity to solve complex problems and how certain mental disorders influence it.

"Have you ever walked to school or work and suddenly seen something that has always been there but that you never noticed before? Since childhood, such moments have made me wonder about what the world really looks like and what is just my perception of it.

A fruit fly walks on a small styrofoam ball fashioned into a floating 3D treadmill. The room is completely dark, and yet, an electrode recording visual neurons in the fly’s brain relays a mysterious stream of neural activity, rising and falling like a sinusoidal wave.

When Eugenia Chiappe, a neuroscientist at the Champalimaud Foundation in Portugal, first saw these results, she had a hunch her team had made an exceptional discovery. They were recording from visual neurons, but the room was dark, so there was no visual signal that could drive the neurons in that manner.
