Using X-ray, radio, and gamma-ray observations of a distant galaxy, a multinational team of astrophysicists has seen perhaps the first live instance of the turning on of a powerful jet from a supermassive black hole.
Researchers performed the first recordings of prefrontal cortical (PFC) neurons from aged monkeys performing a spatial working memory task. They found a marked, age-related reduction in the persistent network firing that is essential for working memory, the building block of higher cognition.
Using a combination of experimental observations, biological and biophysical manipulations, theory, and computation, researchers at Harvard have shown that a "simple" balance of forces insures the consistent coiling and formation of the human gut.
A new study published July 27 in the journal Nature shows that the neural networks in the brains of the middle-aged and elderly have weaker connections and fire less robustly than in youthful ones. Intriguingly, note the scientists, the research suggests that this condition is reversible.
UC Santa Barbara's Kohn Hall, home of the Kavli Institute for Theoretical Physics, has been awarded Leadership in Energy and Environmental Design (LEED) Silver certification by the U.S. Green Building Council (USGBC).
