A new study from Stony Brook University found that the brain's 'taste map' is not composed of clusters of specialized neurons, but rather a network of overlapping and spatially distributed populations. This challenges the long-held theory of taste coding, which proposed a topographic map in the gustatory cortex for specific tastes.
A team of scientists developed a soft, 3D silicone surface that replicates the topography and wettability of a real human tongue. The biomimetic surface demonstrated similar frictional properties to an actual human tongue, making it suitable for studying mechanical interactions with food, liquids, and medicines.
A high-sugar diet reprograms taste cells in fruit flies, leaving a lasting molecular memory that affects future eating behavior. The researchers found that the molecular memory is persistent even after switching to healthy diets, leading to changes in gene expression that impact sweet taste perception.
Researchers found that self-reports of smell and taste changes were better correlated with COVID-19 hospital admissions than current governmental indicators. Smell/taste changes peaked four days after lockdown measures, while hospital indicator peaked 11 days later.
A high-sugar diet in fruit flies reprograms sweet taste receptors, reducing sensitivity to sweetness and promoting unhealthy eating habits. The study suggests that this epigenetic change may contribute to obesity and chronic diseases.
Researchers have discovered that female mosquitoes use four distinct types of neurons to detect the unique flavor of human blood, which may lead to new methods for preventing mosquito-borne illnesses. By studying these taste neurons, scientists hope to develop a drug or treatment that could deter mosquitoes from biting humans.

Researchers found that commercially available baby foods lack dark green vegetable content and flavor, making it difficult for young children to develop a liking for these vegetables. The study suggests that fruit puree dominates the taste and flavor profile of these products.
Researchers found that diet can alter the way sugar tastes in fruit flies, using the same molecular pathways as learning and memory. They discovered that certain diets promote long life also enhance taste perception, and that eating high amounts of sugar suppresses sweet taste perception.
Researchers found that brain regions involved in taste also activate when thinking about food origin. The study used functional MRI to monitor brain activity while participants answered questions about words from different categories.
A recent study found that artificial sweeteners like sucralose can negatively impact insulin sensitivity and glucose metabolism when consumed with carbohydrates. The researchers believe this is due to the gut generating inaccurate messages about calorie availability, which can lead to negative effects on brain function and body response.
Bumble bees prefer normal, low-fat pollen over high-fat versions, which can negatively impact their reproduction and survival. The bees' ability to distinguish between nutrients allows them to make informed food choices.
