Science shows these are the most terrible scents in the world

Few doubts with such a beautiful beauty but hidden in it is the most difficult smell to smell in the world.

If someone asks you, what smell is the worst in the world, will you answer?

That's the smell of rotten eggs, the smell of rotting animals? According to scientists, the most terrible smells are based on their basic molecular structure.

Research from the University of California, Berkeley in 2007 considered 1,500 properties of 150 different molecules to establish the relationship between the "comfort" of a smell and its physical and chemical properties.

Accordingly, molecular weight and electronic density are in fact closely linked to the way we perceive the characteristic of a scent. Put simply, if a larger, heavier distribution molecule tends to be related to odors, while smaller and lighter molecules will be more pleasant.

Scientists have pointed out a few scary scents, which can make you "faint in place" because of its odor.

first.

Scientists at Oxford University discovered clouds on Uranus containing hydrogen sulfide gas (H ₂ S). This is a compound that smells like rotten eggs at concentrations of 3-5 parts per million.

The discovery of clouds on Uranus smells of rotten eggs helps us understand more about the formation of this planet.

Not only is the thorny appearance, durian also makes people hate when it is said to be the "smelly" in the world.

Dr. Martin Steinhaus of the Center for Food Chemistry Research in Germany and his colleagues discovered up to 19 odor-forming compounds identified in durian scent. The most dense odor compounds are the aromas of gymnastics after the gym, the smell of waste water and rotting meat.

Along with that, Singapore experts have identified the gene group methionine gamma lyases - activated when the fruit ripens, creating a "hard to smell" smell specific to durian fruit.

According to Bin Tean Teh, deputy director of the National Cancer Center Singapore (NCC), "The durian smell is described as a mixture of onion sulfur, sweet and spicy fruits. Key in durian odor cannot fail to mention volatile sulfur compounds (VSC), decaying rotten eggs, onions and chives ".

Perhaps it is because of the mixture of so many smells of durian that durian becomes a kind of fruit that makes many people uncomfortable.

Much found in the tropical forests of Indonesia, the famous King or scavenger flower with the scent of incense . the scent is as its name suggests.

Rafflesia arnoldii is a parasite that grows in vines and leaves without leaves, so it cannot be photosynthesis and must be absorbed by nutrients from the host plant - usually a vine Tetrastigma.

Although they smell horrible to humans, they are extremely attractive to insects, helping to pollinate plants.

A good thing for us is that these flowers only live about a week (from 5-7 days old) then dry and die.

4. Boulogne Vieux cheese

As one of the delicious cheeses, made from pure cow's milk in the Pas-de-Calais territory, but according to scientific circles at Cranfield University, Vieux Boulogne is classified as the most difficult in the world.

According to experts, the reason that Vieux Boulogne cheese is "smelly" is because of its soaked shell in beer for up to 9 weeks. The distinctive pungent odor is caused by the fermentation reaction of beer with the enzymes in cheese.

5. Ancient feces

We are certainly terrified of the smell of "delicate waste" or manure. But do you believe any waste exists for 700 years and still smells good?

Archaeologists have discovered 1 in the Danish city of Odense, which dates back to the 14th century, and was more surprised when these delicate waste containers remained smelly until excavation.

6. Antarctic Lesser Anteater

Looks like it looks cute, but this anteater really has a bad smell.

It has been proven that this species is five to seven times stronger than skunks. Anteater eat an unpleasant smell like that to prevent any predators from getting close.
