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–… Source link

Breakdown of every transmembrane protein trafficked to lysosomes requires proteolysis of their hydrophobic helical transmembrane domains. Combining lysosomal proteomics with functional genomic datasets, we identified lysosomal leucine aminopeptidase (… Source link

In mammals, fertilized eggs undergo genome-wide epigenetic reprogramming to generate the organism. However, our understanding of epigenetic dynamics during preimplantation development at single-cell resolution remains incomplete. Here, we developed … Source link

Closed, lossless optical cavities are characterized by a Hamiltonian that obeys Hermiticity, resulting in strictly real-valued resonance frequencies. By contrast, non-Hermitian wave systems are characterized by Hamiltonians with poles and zeros at … Source link

Horses are among nature’s greatest athletes, yet the ancestral molecular adaptations fueling their energy demands are poorly understood. Within a clinically important pathway regulating redox and metabolic homeostasis (NRF2/KEAP1), we discovered an … Source link

In her News story “Cornerstone medical ethics guidelines get a major update” (1 November 2024, p. 473), C. O’Grady describes recent changes to the Declaration of Helsinki (1). Although the revision includes improvements, O’Grady explains that some issues were overlooked, such as obligations to research participants and their communities. These oversights are particularly stark in

How a country evaluates student performance greatly influences the views of its government and citizenry on the quality of its education system and its standing on the global economic stage. Given the impact on future prosperity, health, and well-being, … Source link
