It's often been reported that the human nose can only distinguish between 10,000 scents but new research indicates that the human sense of smell is so impressive, the nose can discriminate over one trillion different odors.
If you smell something, molecules from that object are sticking to the inside of your nose.
Research in 2014 put humans in 13th place in a list of animals with the most genes for smelling. The African elephant came top of the list followed by rats and opossums.
Bears have a third of their brains devoted to smelling, and sharks have two-thirds.
The area of the brain devoted to smell in dogs is 40 per cent larger than humans.
The term "Frito Feet" was coined to describe the scent of dog's feet.
Mazda had to recall 52,000 cars in the US in 2011 due to a species of spider loving the smell of gasoline so much it chose to build its web in the vehicles emission systems.
The Romans believed that the smell of freshly turned soil was so beneficial and wholesome for invalids that they put clods of earth into their beds to help revive their spirits.
The Great Stink was an event in central London in July and August 1858 where the smell of human excrement in the River Thames was so bad that it halted parliament.
A German landlord evicted a tenant in 1981 after they spread surströmming brine, the world's smelliest food, in the building's stairwell. When the landlord was taken to court, the court ruled in favor of the landlord after they demonstrated their case by opening a can inside the courtroom.

On April Fools Day 1965 the BBC aired an interview with the supposed inventor of "SmelloVision" who cut onions and brewed coffee to prove he could transmit scents through a television screen. Viewers called and confirmed that they had received the smells.
The chemical Thioacetone is the world's smelliest substance. It's so rank that, after a lab technician dropped a vial of it, it induced instant vomiting from people in buildings almost half a mile away.
The fresh, salty smell of beach air is actually the smell of rotting seaweed.
The smell that happens after a rain shower is actually three distinct scents: ozone caused by lightning ripping through oxygen and nitrogen in the atmosphere, spores produced by common ground bacteria, and oils produced by plants during dry spells.
The smell of freshly cut grass, though often pleasant, is actually a plant's way of letting out a cry for help.
Crested auklets - the first birds known to signal through scent - smell like fresh tangerines.
Violets can be smelled for only a few moments at a time because they get their scent from ionine which shuts the smell receptors off after simulating them. After a few breaths the scent pops up again but the brain registers it as a new stimulus. So everytime you smell a violet is a first time.
The Japanese word "kareishu" describes the smell of old people.
Domestic gas is scented with a 'rotten egg smell' so it's easier to detect. Gas itself is odorless.
NASA hires a chief sniffer to inspect the smell of every item before it enters space. The lack of ventilation means astronauts are stuck with the smells that are onboard with them.
Space has a distinct smell: astronauts have described the odor as a bouquet of hot metal, diesel fumes and barbecue. The aroma is mostly produced by dying stars.
When astronauts are outside the International Space Station, space-borne compounds adhere to their suits causing a distinctive scent when they return to the station. The smell is so unusual that NASA reached out to a top fragrance maker to re-create the odor for its training simulations.
Astronauts have also compared the smell of the moon to "spent gunpowder."
You can't usually smell your home or your own scent because of a survival instinct called 'olfactory adaptation.' The brain is always looking for new, unusual, or changing smells as a sign of possible danger and ignores familiar scents.
