Using an artificial snot coating mimics natural nose mucus to improve odour discrimination, allowing electronic noses to detect a wider range of smells. The device is compact, affordable, and faster than conventional methods.
Researchers at Indiana University Bloomington found that even when ovary extracts are diluted 100,000 times, some sperm cells still respond to the scent. This discovery may help scientists understand problems with human conception and develop a diagnostic tool for male infertility.
A new study has found that large sinus tumors can be successfully removed endoscopically, with a significant reduction in morbidity compared to traditional open procedures. The procedure involves using tiny scopes and cameras to remove the tumor, which was shown to have a lower recurrence rate than expected.
A joint study by the University of Minnesota and German institutions found that participants' perceived shape of a face influences their verbal estimates and reach movements. The 'hollow-face illusion' showed similar effects on both verbal and reaching tasks, highlighting the importance of object recognition in motor actions.
Researchers mapped airflow patterns through nasal cavity using transparent models, revealing why deep breathing is needed for smelling flowers. The study's findings may aid surgeons and drug companies in developing new treatments.
Scientists discovered pigeons have a magnetic sense beyond simple compass, supporting theory that birds use magnetic map to navigate. The study found magnetic receptors located in the nasal region and suggests magnetite-based ability.
Researchers at the University of Alberta have developed an electronic nose that can recognize and capture ten different smell groupings, including fruits, coffees, gases, and spices. The device connects to a PC and uses inexpensive electronic parts to solve the complex challenge of capturing smells.
Researchers at Johns Hopkins have discovered that a protein called CNGA4 helps the brain adapt to smells by plugging a channel in odor receptor cells. The study found that mice without this protein can't adapt to odors, and the electrical signal from these neurons stays constant over time.
Researchers at the University of Toronto have developed a novel biofiltration technique that uses bacteria to eliminate odors from pulp mill gas streams. The new technology operates at higher temperatures than existing methods, making it more cost-effective and environmentally friendly.
Researchers have developed an artificial nose that senses smell by visualizing color changes in metalloporphyrin dyes, offering improved sensitivity and humidity resistance compared to human noses. The technology has various applications in industries such as food and beverage, perfume, customs checkpoints, and chemical workplaces.
Linda Buck and colleagues found that the olfactory system uses a combination of odorant receptors to recognize different odors. The nose can discriminate a vast number of diverse odorants by recognizing distinct combinations of receptors.
Researchers at Ohio State University developed an electronic nose that can recognize different types of cheese by analyzing key fatty acids. The device correctly discriminated among cheeses and showed promise as a research tool for understanding the human sense of smell.
Researchers have discovered a new method to deliver drugs directly to the brain using nose drops, potentially treating Alzheimer's disease, Parkinson's disease, and multiple sclerosis. The treatment uses nerve growth factor and has shown promising results in animal studies.
