Researchers have demonstrated that electrons can move freely in layers of linked semiconductor nanoparticles under the influence of light. This new knowledge will be very useful for the development of cheap and efficient quantum dot solar cells.
Arthur Horwich, Sterling Professor of Genetics & Pediatrics, received the Albert Lasker Basic Medical Research Award from the Albert and Mary Lasker Foundation for his work on the process of protein folding, or formation.
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.
