In a proof-of-concept study led by the School of Veterinary Medicine, dogs identified positive samples with 96% accuracy.
Lemurs can use their sense of smell to locate fruit hidden more than 50 feet away in the forest--but only when the wind blows the fruit's aroma toward them.
Odors evoke powerful memories, an experience enshrined in literature by Marcel Proust and his beloved madeleine. A new paper is the first to identify a neural basis for how the brain enables odors to so powerfully elicit those memories. The paper shows unique connectivity between the hippocampus--the seat of memory in the brain--and olfactory areas in humans. It's like a superhighway from smell to the hippocampus.
* Natural compound found in catnip is at least as effective as synthetic insect repellents such as DEET * Catnip can easily be grown in a home garden and made into oil or extract * New type of deterrent targets pain receptors in insects while maintaining no impact on humans
Wine lovers recognize that a perfectly paired wine can make a delicious meal taste even better, but the reverse is also true: Certain foods can influence the flavors of wines. Now, researchers reporting in ACS' Journal of Agricultural and Food Chemistry have explored how lipids -- fatty molecules abundant in cheese, meats, vegetable oils and other foods -- interact with grape tannins, masking the undesirable flavors of the wine compounds.
Olfactory dysfunction or partial loss of smell is one of the earliest symptoms of Alzheimer's disease (AD). While accumulation of the toxic amyloid β protein in the brain is known to drive AD progression, its involvement with olfactory sensory neurons is poorly understood. Researchers have now dug deeper into the molecular mechanisms underlying olfactory dysfunction by assessing behavioral, physiological, and anatomical changes in a mouse model of AD. These findings could help reveal therapeutic targets for AD.
Study show for the first time that dim red light activates olfactory gene pathways in the antennae of a model species, the yellow peach moth, increasing the sensitivity of males to female sex pheromones, and ultimately promoting reproductive behavior
People with COVID-19 may lose their sense of smell and taste for up to five months after infection, according to a preliminary study released today, February 22, 2021, that will be presented at the American Academy of Neurology's 73rd Annual Meeting being held virtually April 17 to 22, 2021.
It's a first: scientists in Portugal have discovered that measurements of food reward may be useful to identify, beforehand, which patients with obesity will achieve greater weight loss from surgery to treat obesity (a.k.a bariatric surgery). This is an important step not only towards a more personalized evaluation of the potential efficacy of the procedure but also towards understanding the biological mechanisms that underlie the effects of surgery and lead to weight loss.
Opertech Bio, Inc., today announced the publication of a seminal research article describing the application of its pioneering TāStation® technology to the pharmacological characterization of human taste discrimination. The findings are published in the peer-reviewed Journal of Pharmacology and Experimental Therapeutics, JPET.
