Using molecular genetics, American researchers from the universities of Michigan and Houston have tried to find out why. And they have managed to show that the odor that most alters physiology and affects longevity is that of carbon dioxide (CO 2 ) . According to a series of experiments, genetically modified flies that have lost the ability to smell CO 2 live longer than those with normal olfactory abilities. In addition, they are more resistant to stress. "We are working hard to understand how sensory perception affects health," explains Scott Pletcher, head of the study. "Somehow there is a group of neurons whose main task is to detect CO 2 that are capable of causing changes that accelerate aging ." The challenge now is to understand how.
Are there smells that shorten life?
Recent studies in model organisms (flies, mice …) and in humans have revealed that sensory experiences can have an important impact on health issues, on athletic development and on the rate of aging . Specifically, it has been confirmed that worms and fruit flies that are unable to smell or taste live longer .

Insect swarms generate as much electricity as a thunderstorm
Swarms of bees can generate an electrical charge of 1,000 volts per meter, a higher voltage density than thunderclouds and electrified dust storms.

Days were only 17 hours long 2.46 billion years ago
It was when the Moon was much closer to our planet. As the centuries pass, the Moon slowly recedes and the length of our day gradually lengthens accordingly.
