Hedonic eating is defined as food consumption driven by palatability without physiological need. However, neural control of palatable food intake is poorly understood. We discovered that hedonic eating is controlled by a neural pathway from the peri–locus ceruleus to the ventral tegmental area (VTA). Using photometry-calibrated optogenetics, we found that VTA dopamine (VTADA) neurons encode palatability to bidirectionally regulate hedonic food consumption. VTADA neuron responsiveness was suppressed during food consumption by semaglutide, a glucagon-like peptide receptor 1 (GLP-1R) agonist used as an antiobesity drug. Mice recovered palatable food appetite and VTADA neuron activity during repeated semaglutide treatment, which was reversed by consumption-triggered VTADA neuron inhibition.

The Standard Model of Cosmology has reigned supreme for decades, confirmed over and over again. But chinks in the armour have been developing, such as the Hubble Tension. Now, however, a new result threatens to completely upend our view of the Universe — we no longer even know how it will end.

What do smart bandages, ocean-powered sensors, and quantum biology have in common? They’re all part of Dr. Leonard Tender’s work at DARPA. On the latest episode of Voices from DARPA, he discusses his fascinating research in the Biological Technologies Office and how these innovations are shaping the future of national security.
🌎 Immerse yourself in the futuristic atmospheres of Aethelburg, an imaginary city that evokes the atmospheres of Blade Runner 2049. This video features a static image of a futuristic metropolis, accompanied by my original composition of ambient cyberpunk music. Let yourself be enveloped by the evocative sounds and suggestive images of this city of the future.
Music composed by Paolo Bellucci and produced by Bear Cave Studio, inspired by the atmospheres of Blade Runner 2049, ideal for relaxing, concentrating or simply daydreaming.
🎹 Inspired by Sci-Fi and Fantasy, we use a combination of analog and digital synthesizers to create lush soundscapes and ambient music ideal for escaping reality.
