You may have heard that adog nose is up to 100 million times more sensitive than our nose, soDogs can omit convulsions before they start and caneven feel cancer. But now, a new study published in the newspaperScientific reports suggests aThe dog nose has another superpower: It can take the heat heat.

This cold, wet and coriastimate at the end of a dog's nose that humans like boop so called the rhinarium. Compared to other animals, the nose of a dog is usually a few cold degrees than the temperature of the environment, which scientists have previously attributed to the regulation of body temperature. But the researchers involved in this new study have hypothesized that the cold noses of dogs can help them detect weak heat - a capacity that only a handful of animals, such as vampire bats and firebeams Black, are known. It would help explain whyDogs with diseases or audience can still hunt successfully.

To test their theory, the researchers formed threepet dogs Choosing between an object that was the ambient temperature and the one that was warmer than the ambient temperature. The objects were placed at about five feet and covered so that dogs can not see or feel them. In a series of double-blind experiments, the three dogs were capable of detecting which objects emitted a weak thermal radiation.

Then they scanned the brains of 13 pet dogs while showing them objects that had neutral radiation or low thermal radiation, and found that the left somatosensory cortex - which provides information from the nose to the brain - illuminated in response. Hot stimulus. More incredible, the radiation was so low that the scientists had to touch the surfaces of the objects to see if they were hot, involving that the nose of a dog is even more sensitive to the thermal heat than the human hands.

More research must be conducted to assess how this evolving trait has developed, but it is another example that shows that there isno shortage of incredible skills dogs have.
