Your Very Weird, Very Personal Sense of Smell. We’re used to the idea that some among us are colorblind, perceiving the world differently because of a quirk in their genetics.
And it’s well-known that teenagers and young adults can hear high-pitched sounds that their elders cannot, an ability that’s been exploited by manufacturers of The Mosquito, an anti-loitering device that annoys youth into leaving. But perhaps because the effects are harder to compare easily, or perhaps because we have such a hard time talking about them, we tend to overlook some rather peculiar differences in our senses of smell. When people get a whiff of a molecule called androstenone, they may say it smells like sandalwood, or vanilla—or they might say it has a sickening, urine-like tang. Or they might think it entirely odorless. There are around a dozen known chemicals that provoke this kind of disagreement, scientists think. There’s a large body of research surrounding androstenone.
Humans Theorize. Cosmos, Moby’s Song ‘We Are All Made of Stars’, Universe & Solar System. The theory that everyone and everything on Earth contains minuscule star particles dates back further than Moby's popular 2002 song "We Are All Made of Stars.

Could Humans Walk on Water? For centuries, humans have floated the idea that we might, one day, walk on water.

Perhaps we were inspired by nature more than 1,200 species of animals can walk on water .
Odd Gender Differences Found in Walking. If we see a shadowy figure walking down a dark street, our sense of whether it is coming at us or walking away depends on whether we see it as a he or a she, new research finds.
