Scientists Find Neural Pathways Responsible for Impulse Eating
Researchers were surprised to find that fruit flies were given to impulsive eating patterns, similar to humans who will eat more of a food if it contains large amounts of sugar and fat.
What's the Latest Development?
Researchers at the University of Georgia have found the pathway in the brain that is responsible for impulse-eating, and while the experiment involved fruit flies, evolutionary patterns make the results applicable to humans. "To test reward-driven behaviors in flies, [the researchers] introduced appetizing odors to groups of well-fed larvae. In every case, the fed larvae consumed about 30 percent more food when surrounded by the attractive odors. But when the insects were offered a substandard meal, they refused to eat it."
What's the Big Idea?
The fruit flies' behavior was similar to humans who might turn down a healthy, though less flavorful meal after having become accustomed to fatty and sugary foods. The similarity in behavior highlights the potential of the research to benefit human health. "It is very hard to control this impulsive urge. So, if we understand how this compulsive eating behavior comes about, we maybe can devise a way, at least for the behavioral aspect, to prevent it. We can modulate our behaviors better or use chemical interventions to calm down these cues."

Are university safe spaces killing intellectual growth?
Our experience of time may be blinding us to its true nature, say scientists.
- Time may not be passing at all, says the Block Universe Theory.
- Time travel may be possible.
- Your perception of time is likely relative to you and limited.
From questionable shipwrecks to outright attacks, they clearly don't want to be bothered.
- Many have tried to contact the Sentinelese, to write about them, or otherwise.
- But the inhabitants of the 23 square mile island in the Bay of Bengal don't want anything to do with the outside world.
- Their numbers are unknown, but either 40 or 500 remain.
