Protein from the liver may cause Alzheimer's disease in the brain

  • No comments
Summary: Amyloid-beta proteins formed in the liver are carried in the bloodstream by lipoproteins to the brain. This causes neurodegradation, brain degeneration and inflammation, common features of Alzheimer's disease.
(The graphic illustration describes the research findings and shows that stories affect our heart rate and bind us together. The researchers found that attention to narratives may synchronize heart rate fluctuations between different individuals. Cardiac synchronization predicts memory and cannot be explained by breathing) Credit: Perez and Madsen et al./Cell Reports

Heart rate synchronization when listening to stories together

  • No comments
Heart rate synchronization occurs, even when subjects are listening to a story alone, when they are attentive to certain points in the story

On the map, which you can see above, the focal point from which the lines come out is at the point where the earth is located. To his right the older stars (red) around the center of the galaxy and to his left the younger stars (blue) in the outer parts of the disk. As the researchers in the group say, the Milky Way galaxy has grown outward over time.

Not just the entire universe: the Milky Way galaxy is expanding outward over time
