The EXO team announced yesterday at a conference in Munich that, according to their measurements of two-neutrino double-beta decay in Xe-136, an isotope of xenon, the half-life of the process clocks in at 2.11 x 10^21 years.
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.
