Why does the water in my house still smell?
A new study from researchers at the University of Queensland in Australia suggests that it may be the human body’s way of communicating the smell of decomposing body parts.
According to the researchers, the human sense of smell was first used to identify the smell in the human digestive tract when it was first discovered by the Roman historian Tacitus in the first century BC.
Using their new study, the researchers tested the sense of touch and found that the sense can be activated when a person is exposed to the smell.
This is particularly useful for finding out if the human can sense the smell when it comes to decomposing bodies.
“The smell is detected in the stomach, stomach contents, intestines, intestinally-associated organs, and the respiratory and cardiovascular systems,” the researchers wrote in the study, which was published on February 3 in the journal Proceedings of the National Academy of Sciences.
“So the smell can be sensed when a body is decomposing.
So it is like a sense of hearing a sound or feeling a temperature.”
The researchers also discovered that the smell is activated when the body is being decomposed, with the researchers hypothesising that this could be the reason why decomposing corpses can sometimes smell like their dead relatives.
“In a human body, the smell molecules are not only detected by the skin, they can also be detected by smell receptors on the nose and mouth,” Professor David H. Wilson, from the University’s Department of Anthropology and the Department of Zoology, said.
“What we have shown is that smell can also activate the sense and that this can be an important sense of how to communicate with other animals.”
The smell of the decomposing remains of humans is the most recognisable smell in Australia.
According the researchers’ findings, the scent of the human remains can be detected in a wide range of other body parts including the eye, nose and throat.
“There is no clear signal as to whether this is a primary sense of body odour or a secondary sense,” Professor Wilson said.
“The fact that the brain processes smell in this way is consistent with how we sense smell in humans.”
