香りの科学 Could Nasal Mucus Help Explain Age-Related Changes in Smell?
A proteomic study identified 2,987 proteins across 24 participants and explored differences by nasal location, age, and olfactory sensitivity.
香りの科学 Can AI Predict Odor Strength from Molecular Structure?
A 2026 study predicted odor strength from molecular structure. AI trained on 2,393 molecules in four categories, odorless, low, medium, and high, achieved 72% agreement in testing. We examine its predictive clues and limitations concerning concentration and perfume applications.
香りの科学 Does Odor Perception Differ by Region?
A study of 909 people in 16 regions examined odor perception across 12 dimensions. Region was more strongly associated with intensity ratings than pleasantness. We explore what the roughly 10% explained by region means and why it cannot be generalized to national preferences.
香りの科学 How Did Clary Sage Acquire the Ability to Make a Fragrance Raw Material?
How did clary sage acquire the ability to produce sclareol, a starting material for fragrance manufacturing? A 2026 study traces gene duplication, changes at six positions in an enzyme, and regulation of genes active in floral glandular trichomes.
香りの科学 More Than “Stinky”: 25 Words for Describing Body Odor
How can we describe body odor beyond liking or disliking it? We introduce a 25-word list developed from a survey across 17 countries and regions in 13 languages, and its validation using real odor samples.
香りの科学 Are Feminine and Masculine Smells Determined by Molecules?
At a museum, 2,716 people evaluated two compounds involved in sweat odor. Differences in perceived femininity and masculinity were very small, and pleasantness was also associated with the ratings. We explore the relationship between molecules and impressions.
香りの科学 How Do Breathing and Heart Rate Change with a Scent You Like?
What happens to breathing and heart rate when you smell a scent you like? A 30-person experiment helps distinguish physiological measurements, brain activity, and the relaxation people actually feel.
香りの科学 Can Meeting and Talking Change the Impression We Form from Someone’s Scent?
How does the impression of a person formed from the same smell change before and after meeting them? A study uses worn T-shirts containing everyday fragrances and odors, alongside four-minute conversations.
香りの科学 Does a Self-Selected Perfume Suit Your Body Odor?
Does perfume uniformly mask body odor? Three experiments from 2012 explore the combination of fragrance and body odor, and what choosing a perfume for yourself might mean.
