JUNE 10, 2024 by Laura Williamson, American Heart Association Credit: Pixabay/CC0 Public DomainLosing the ability to smell properly—a common sensory deficit as people age—may help predict or even contribute to the development of heart failure, new research suggests. The study, published in the Journal of the American Heart Association, adds to a growing body of...

The study, carried out in collaboration with the National Institute for Health Innovation and published in the journal Appetite, assessed the potential effects of vaping on the sense of taste and smell among...
by Radiological Society of North America Infographic—New Treatment Restores Sense of Smell in Patients with Long COVID. Credit: RSNA Using an image-guided minimally invasive procedure, researchers may be able to restore the sense of smell in patients who have suffered with long-COVID, according to research being presented next week at the annual meeting of the Radiological...
JOHNS HOPKINS MEDICINE In a study that followed more than 2,000 community-dwelling older adults over eight years, researchers at Johns Hopkins Medicine say they have significant new evidence of a link between decreased sense of smell and risk of developing late-life depression. Their findings, published June 26 in Journal of Gerontology: Medical Sciences, do not demonstrate that loss...
By Medscape Staff March 29, 2023 Problems with a sense of smell may help predict a higher risk for age-related health problems, according to researchers from the Department of Otolaryngology-Head and Neck Surgery at Johns Hopkins University School of Medicine. What to know: Smell dysfunction acts as an early indicator of cognitive decline as well as signs...
UNIVERSITY OF CALIFORNIA – SAN FRANCISCO Breaking a longstanding impasse in our understanding of olfaction, scientists at UC San Francisco (UCSF) have created the first molecular-level, 3D picture of how an odor molecule activates a human odorant receptor, a crucial step in deciphering the sense of smell. The findings, appearing online March 15, 2023, in Nature, are poised...
by Harrison Tasoff, University of California – Santa Barbara Under the previous model (top), an odor would activate an increasing number of olfactory sensory neurons as it’s concentration rose. The new findings (bottom) showed that the activity of the most sensitive neurons fell off as others joined. Credit: TADRES ET AL. The delicate fragrance of...
by Ola Nilsson, Umea University Release of vesicles with transduction proteins in electron microscope magnification. Credit: Devendra Kumar Maurya Researchers at Umeå University have discovered a previously unknown cellular component, an organelle, inside neurons that we use to perceive smell. The discovery may have implications for further research on impaired sense of smell, which is a common symptom...
by Massachusetts General Hospital Credit: Unsplash/CC0 Public Domain An olfactory receptor gene that aids in the sense of smell may also play a role in the metastasis of breast cancer to the brain, bones and lung, researchers from Massachusetts General Hospital (MGH) have found. The team further discovered that inhibiting the gene, OR5B21, significantly decreased the...
UNIVERSITY OF COPENHAGEN – FACULTY OF SCIENCE Contrary to what science once suggested, older people with a declining sense of smell do not have comprehensively dampened olfactory ability for odors in general – it simply depends upon the type of odor. Researchers at the University of Copenhagen reached this conclusion after examining a large group...
