Illinois News Bureau: Online smell, taste challenge offered as early detection tool for COVID-19. “A brief smell and taste challenge, developed by the Global Consortium for Chemosensory Research, is a web-based tool people can use to easily monitor changes in these senses using their favorite morning beverage.”
EurekAlert: Scientists develop AI-powered ‘electronic nose’ to sniff out meat freshness. “The ‘electronic nose’ (e-nose) comprises a ‘barcode’ that changes colour over time in reaction to the gases produced by meat as it decays, and a barcode ‘reader’ in the form of a smartphone app powered by artificial intelligence (AI). The e-nose has been trained to recognise and predict meat freshness from a large library of barcode colours.”
Phys .org: The smell of old books could help preserve them. “Old books give off a complex mélange of odors, ranging from pleasant (almonds, caramel and chocolate) to nasty (formaldehyde, old clothes and trash). Detecting early signs of paper degradation could help guide preservation efforts, but most techniques destroy the very paper historians want to save. Now, researchers reporting in ACS Sensors have developed an electronic nose that can non-destructively sniff out odors emitted by books of different paper compositions, conditions and ages.”
