Biosensors mimic the human olfactory system and distinguish between very similar odors.
Shift of the electrostatic dipole of hOR1A1 with structural changes. Credit: Lugunas et al. ChemRxiv (2024). DOI: 10.26434/chemrxiv-2024-kxx8d The human olfactory system distinguishes between thousands of odors by specifically interacting with olfactory receptors on sensory neurons. Each receptor can detect multiple odorants at different intensities, and the same odorant can activate multiple receptors. This complex combination of signals generates our…

Meat has a unique taste, texture, and aroma. Biochemist explains how plant-based alternatives mimic the real thing
Credit: CC0 Public Domain When you bite into a juicy hamburger, slice into a perfect medium-rare steak, or munch on a plateful of chicken nuggets, your senses are probably responding to the smell, taste, texture, and color of your food. For a long time, these four characteristics have distinguished meat from other food groups. But in recent years, food companies…

New molecule can mimic the effects of fasting and exercise
The diagram on the left shows the chemical structure of LaKe. The graph on the right shows how blood lactate and ketone body (BHB) concentrations change over time in rats ingesting LaKe (blue curve) or a control substance (black curve). Both lactate and BHB are found to be significantly increased in rats fed LaKe. Credit: Aarhus University/Thomas Poulsen It is…
