28 lut 2021 · Now, a team of researchers at MIT and other institutions has come up with a system that can detect the chemical and microbial content of an air sample with even greater sensitivity than a dog’s nose.
22 cze 2022 · The 300 million scent receptors in a dog’s nose are routinely used to detect bombs, drugs, firearms and people. But dogs are now being used experimentally to sniff out human disease.
21 sty 2023 · Dog noses have up to 300 million olfactory receptors, compared to roughly 6 million in humans, and have a 40 times larger brain area devoted to scent analysis. Furthermore, dogs have neophilia, which makes them drawn to new and exciting odors (Phoenix Veterinary Center, 2023).
17 lut 2021 · A new system can detect the chemical and microbial content of an air sample with even greater sensitivity than a dog’s nose. Researchers at MIT and elsewhere coupled this to a machine-learning process that can identify the distinctive characteristics of the disease-bearing samples.
18 lut 2021 · Inspired by the incredible olfactory senses of dogs, scientists have been developing and demonstrating different types of “electronic noses” that can sniff out things like cancer, nerve gases...
21 sie 2021 · The canine olfactory system can recognize more smells than it has receptors for scent molecules, but olfactory receptors can have specific cross-reactions, building unique systems of...
29 mar 2018 · The ability to find the source of the scent, even in the presence of competing odors, makes the detection dog a critical partner in many military, law enforcement, and search and rescue operations. During inspiration, 12–13% of air flow travels to the olfactory portion of the nose, and the remaining airflow is directed toward the nasopharynx ...
