I was never a pillowcase kid. Fill the sheets that I put my head on with the goods, risking an errant Mr. Goodbar besmirching my sleeping quarters? No thanks. Besides, a pillowcase would need to go in the wash eventually. My plastic pumpkin was a dedicated trick-or-treating device. And somehow, it managed to stay…
Losing your sense of smell takes away more than scents and flavours – it can fundamentally change the way you relate to other people.
Smells are really good at stirring up memories, especially ones from adolescence. Which is curious, because these memories are often the hardest to access. In the latest episode of SciShow, Hank Green reviews some of the research on why smells are such potent triggers of early memories.
The sensory chaos of battle has always posed a challenge to armies hoping to prepare for—and recover from—war. And while it’s clear to most people how sight and sound factor into a soldier’s experience and memory of battle, the smells of combat were, for most of history, largely ignored. But by the eve of the 20th…
When you're hacking your way through a sweltering jungle in virtual reality, wouldn't you like to feel as disgustingly hot and humid as your video game character? To smell that distinctive jungle scent? No? Then you'd sure as hell better not pay $250 for the Feelreal this summer.
Dogs have an extraordinary sense of smell—a complex nasal architecture that lets them pick up scents and distinguish the chemical composition of hormones released by other animals. Alexandra Horowitz explains how this happens in an interesting TedEd lesson. Check it out:
Now we've gotten closer than ever to a comet in space, we can start answering serous scientific questions, like... err, what such a thing smells like?
It's easy to notice on a street corner, but hard to track as you navigate an entire city: smell, despite being a crucial stimulus, is much harder to quantify than other sensory cues like sound or light. But that hasn't stopped Kate McLean from trying.
If you've ever had a dog that was a particularly finicky eater or marveled at just how appetizing they seem to find those endless bowls of kibble, you've probably wondered: Just how sensitive is a dog's sense of taste?
Why do armpits smell so bad? Well, those millions of bacteria have to live somewhere.
Common wisdom holds that smell is the least important sense for our species. But that conclusion may be flawed because we've ignored non-Western cultures. New research on a small tribe in southern Thailand challenges that assumption.
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.
"The human sense of smell is far better at guiding us through our everyday lives than we give it credit for," said cognitive neuroscientist Johan Lundström. He was referring to what he and a research team just discovered, which is that humans can actually tell how much fat is in their food just by smelling it.
Think back to when you were a child visiting your grandparent's home. Do you recall a distinct scent when you walked through the door? Many people do and it turns out, it's not just in your head.
Have you had trouble shaking that fear of snakes or dogs or spiders? Researchers from Northwestern University have developed a new technique to rechannel memories while subjects sleep—by blasting them with various odors. It's like Eternal Sunshine of the Spotless Mind in Smell-o-Vision.
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.
Doesn't it seem like being able to smell a TV show would be undesirable a lot of the time? Alex Trebek's cologne would be wafting around your grandma's all through Easter dinner and then your house would smell like blood after the Game of Thrones premier.
We already have white noise, and now there an equivalent for smell. Scientists in Israel believe they've identified "olfactory white", a blend of dozens of components that smells — well — totally neutral.
Imagine eternally odorless public restrooms, or stink-free changing rooms. Amazingly, researchers claim to have discovered what they're calling a "white smell"—an odor made up so many complex aromas that it's neither pleasant or foul-smelling, in no way overwhelming, and could be the most effective air-freshener ever.
