21 sty 2023 · Whether it's detecting a fire or determining if food is safe, our nose is often the first to let us know something is wrong. Inspired by the outstanding canine scent, researchers are now designing advanced olfactory machines based on the intricate neuroscience that underpins our olfactory abilities.
28 lut 2021 · Trained dogs can detect cancer and other diseases by smell. A miniaturized detector can analyze trace molecules to mimic the process. Numerous studies have shown that trained dogs can detect many kinds of disease — including lung, breast, ovarian, bladder, and prostate cancers, and possibly Covi
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.
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.
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 ...
22 cze 2022 · However, a small but growing group of scientists is pursuing another avenue: olfactory implants that restore smell by bypassing the peripheral olfactory system and electrically stimulating the...
19 lip 2022 · A dog’s brain is wired for smell. Now, a new map shows just how extensive that wiring is. Powerful nerve connections link the dog nose to wide swaths of the brain, researchers report July...
