World Cup 2014 has been described by many as the best ever for the exciting play and huge number of goals. And, as the tournament has progressed, the drama has increased, with hard fought games going to…

Luis Suárez has struck again. For the third time now, the Uruguayan striker faces charges for biting an opponent and there is no defending this kind of behaviour on a sports pitch. While no one knows for…
Melanopsin pigment in the eye could be more light sensitive than the pigment that allows for night vision, rhodopsin. A two-year…
Colour blindness tests on shrimp have quashed assumptions that more complex eyes mean better colour vision. Scientists found…
In the featureless open ocean, perceiving distance can often prove an issue for divers and marine animals alike. A recent…
A group of cells within the brain that helps humans avoid accidents have been identified. The cells detect edges and help…
Landing is arguably the most nerve-racking element of any flight. To execute a safe landing, a pilot needs to know the plane’s speed and its distance from the landing surface. The pilot’s challenge is…
As humans, we experience an amazing world of colour, but what can other animals see? Some see much more than us, but how they use this vision is largely unknown. We see what we see because our eyes have…
More than one in ten middle-aged people has difficulty following speech in noisy environments, according to an analysis of 165,000 people in the UK Biobank, a project following the health of half a million…
The new treatment of inherited blindness in dogs might help restore vision to humans too. A combined study lead by Michigan…
The fly larva brain’s ability to process visual information can make up for low visual input. Researchers discovered that…
The eye is perhaps one of the best examples of Darwinian evolution. Incremental steps driven by natural selection have led to the evolution of this complex organ from its origin as a simple light-sensitive…
Here are six test tubes filled with coloured dyes. How many different colours do you see? Most people say six, but some people would say only two or three. There are even some (very rare) people who see…
It is no coincidence that flowers have evolved to display the same coloured petals in different continents, according to…
As you read this article your eyes will move so the words fall on the central part of your vision. This region is called the fovea and it has excellent resolution when compared to your peripheral vision…
Small aberrations are produced by the cells of the primary visual cortex, distorting optical information even before the…
Many animals have better colour vision than humans and many have polarisation vision, which allows them to see a colour dimension…
The path to development of the bionic eye is blindingly clear but progress is slow. There’s been an explosion of research into retinal and brain-based bionic eyes and the race to develop one has started…
