Click here to view original web page at tRNA Fragments Linked to Alzheimer’s
Summary: A new study identifies a crucial factor in brain aging and Alzheimer’s disease—the accumulation of Glu-5’tsRNA-CTC in neuron mitochondria. This small RNA fragment disrupts mitochondrial protein synthesis and cristae structure, accelerating cognitive decline and Alzheimer’s pathology. By targeting these tRNA fragments with antisense oligonucleotides in aged mice, the […]

Summary: Researchers developed a computational model revealing why certain experiences become memorable while others are forgotten. Their study suggests that our brains are more likely to remember experiences that are difficult to explain or interpret. Using a combination of this model and behavioral experiments, they found that images which […]

Summary: Researchers made significant advances in understanding parasomnias—complex sleep behaviors where individuals are semi-conscious, often interacting with their environment. The team explored brain activity during these episodes, revealing that dreams and unconscious actions can occur during non-REM sleep, challenging previous assumptions about sleep stages and dream occurrence. By inducing […]
