Dogs are the most adorable and faithful companion of humans. No matter if there will be none with you, but your four-legged friend will always be beside you even in the darkest of night. Sniffers by nature, dogs are more than curious to explore the world and surroundings with their nose. It’s no big secret that dogs have an excellent sense of smell, certainly much better than our human noses. In the era where technology has emerged to an ultimate level, we still have this simple kind animal with incredible powers that can dwarf a machine’s ability.
A dog can be a simple companion for us but the evolving troubles have adopted dogs for more than just their friendship. Let’s know how.
Much More Than A Pet
An experimental Biology Meeting was organized from April-6 to April-9, 2019 at Orlando, Fl. Junqueira was all prepared to present the research at the American Society for Biochemistry and Molecular Biology annual meeting, one of the events that took place in the Experimental Biology Meeting.
Dogs possess 10,000 times more accurate smell receptors than humans that make them highly sensitive to odors that we can’t perceive. According to the latest study, dogs can use their highly evolved sense of smell to pick out blood samples from people with cancer with almost 97% accuracy.
How a dog’s nose functions?
The human nose works as a respiratory and scent detective device. Unlike humans, a dog’s nose separates those two functions. On part of their nose is dedicated to respiration while another part is taken to regions just to scent. A dog can continuously smell while it breathes and exhales. If this isn’t enough sniffing power, a dog has a secondary smelling organ called Jacobson’s organ.
Healthier Junquiera, the lead researcher at the BioScentDx, performed a study. Junquiera along with her colleagues used a form of clicker training to teach four beagles (a short-haired black and brown dog with long ears and short legs) to distinguish between normal blood serum and samples from patients with pernicious lung cancer, according to Science Daily. Although one beagle was unmotivated to perform, the other three dogs correctly identified lung cancer samples 96.7% of the time and normal samples 97.5% of the time. Moreover, Junquiera said that “Although there is currently no cure to cancer, early detection offers the best hope of survival”.
Junquiera also mentioned that this research paves the way for further research along with two paths, both of which could lead to new cancer detection tools. “One is using canine scent detection as a screening method for cancers, and the other would be to determine the biologic compounds the dogs detect and then design cancer-screening tests based on those compounds”.
As a result, BioScentDx plans to use canine scent detection to develop a non-invasive method of screening for cancer and other diseases. Moreover, BioScentDx isn’t the only lab that offers scent based on cancer detection. But, Junquiera warns consumers to do their research before making the choice, saying other companies may lack the science and data to support their claims.
