- The heart maintains a careful balancing act; there is an optimal amount of strain that a beating heart can generate and still beat at its usual rate, once per second. Research now shows that this “sweet spot” depends on the stiffness of the collagen framework that the heart’s cells live within. http://www.upenn.edu/pennnews/news/researchers-penn-show-optimal-framework-heartbeats 4 comments science
- Memories are ‘geotagged’ with spatial information: Using a video game in which people deliver objects to specific locations, neuroscientists have discovered how brain cells that encode spatial information form “geotags” for specific memories and are activated just before those memories are recalled. http://www.upenn.edu/pennnews/news/memories-are-geotagged-spatial-information-penn-researchers-say 39 comments science
