Mammals can sniff out Danger

Scientist at the University of Lausanne has said that mammals can communicate danger to each other through smell. The scientist found that when placed in an environment where there is a beaker of water containing warning pheromones emitted by other mice, the animals are able to immediately sniff out the danger and move away. The mice’s reaction has been attributed to the 300 to 500 cells their noses, called the Gruenberg ganglion. This ganglion is present also in humans, according to Hans Gruenberg who discovered it in 1973. And the Swiss researchers believe that “One can imagine that humans have a similar method of communicating danger to each other.
