If dogs have such a keen sense of smell, why do they spend so much time with their noses near each other's rear ends? This video gives a quick introduction to dog butt science and explains why their noses aren't overwhelmed by the smell of poop.
There is an oft-referenced factoid, reproduced everywhere from websites to textbooks, that the human nose can distinguish between 10,000 smells. But a recent investigation has revealed this under-investigated figure to be off. Like way, way, way off.
Ever wonder why some people think cilantro tastes like detergent while others scatter it over everything? Or why brussels sprouts are delectable to some and disgusting to others? Part of that difference of opinion may lay in our genes.
Losing your sight early in life is often said to heighten other senses, particularly hearing. A new study now shows that even a short, weeklong stint in complete darkness can result in superhuman hearing, at least temporarily. This suggests that a kind of darkness therapy may help restore hearing to adults suffering…
How people develop long-lasting taste aversions has intrigued scientists for decades. Surprisingly, research now shows this phenomenon doesn't occur in the brain area involved in taste perception, as previously believed — this discovery could not only help us better understand our taste system, but also why people eat…
We’ve got categories to describe our perceptions of taste, colors, and sounds. But things aren’t as clear-cut when it comes to our sense of smell. Looking to overcome this surprising limitation, a team of researchers have proposed a list of 10 basic smells.
Every human has limits. You can only run so fast, jump so high, and go for so long without water. But what about restrictions upon our five senses, those tools that we use to perceive and understand our surroundings? Here are ten limitations on human perception that have a direct impact on how we understand the world.
Anyone who has ever put off their lunch break just a little too long knows how much hunger can mess with your head. But hunger doesn't just change how we think. It can fundamentally alter how we perceive the world.
We are taught that, as we stumble through the world, we have touch, taste, smell, hearing, and sight to guide us. It turns out that we have been underestimating ourselves. Scientists count between fourteen and twenty actual senses, most of which aren't taught in primary school. See what information you're really…
We all know that mermaids can perform underwater musical numbers. But how would a real-life mermaid sing underwater? And hear music? Find out in our guide to underwater physics for mermaid chasers.
It turns out that the impossible buildings and bizarre objects dreamed up by artists like M.C. Escher tap into an incredibly primal understanding of the world's geometry, a knowledge that is hard-wired into all vertebrates, including newly hatched chickens.
As we get older, our senses actually "fuse" together, and we lose the ability to focus on isolated pieces of sensory information. This means adults perceive certain events far more accurately than children can... and vice versa.
