The team found that single-taste neurons are capable of responding to more than one tastant category, and that a single tastant category can activate multiple classes of taste neurons.
A panel of amateur beer drinkers distinguished between five barley varieties, preferring four developed at WSU over a control. The researchers hope this method can be used to test new barley varieties and reduce reliance on hops.
Researchers found that songbirds can sense sweetness regardless of their primary diets, with the ability emerging early within the songbird radiation. The team identified the molecular basis of this ability and found that it has been conserved in nearly half of all birds living today.
A recent study published in Science found that songbirds can indeed taste sugar, contrary to long-held assumptions. The researchers' findings suggest that songbirds evolved to sense sweetness approximately 30 million years ago, possibly due to the availability of sugary food sources.
Pleasure-seekers tend to buy impulsively when in a positive state, but can suppress impulse with minimal note reminder. Security-oriented individuals need time and often look for 'no impulse buying' reminders to act.

The team discovered that taste dysfunction persists for years after treatment ends, affecting the quality of life for these individuals.
Research finds that fruit flies use two distinct types of gustatory receptor neurons to discriminate between low and high concentrations of acid, explaining why many animals are attracted to slightly acidic foods but repulsed by highly acidic ones. A key protein, Otopetrin-like, plays a crucial role in attractive sour taste response.
The study found that animals have evolved to prefer tastes that correspond with their elemental needs, helping them prioritize nutrient-rich foods. Convergent evolution was observed across mammalian, fish, and insect groups, highlighting the importance of taste in foraging and nutrient cycling.
A study found that witnessing moral transgressions can inhibit tongue movements, similar to tasting something unpleasant. This reaction may reflect an avoidance-defensive mechanism, adapting as a response to shared moral norms.
