Jul 23 - UNIVERSITY PARK, Pa. The discovery of a new material combination that could lead to a more efficient approach to computer memory and logic will be described today (July 24) . The research, led by Penn State and Cornell University physicists, studies "spintorque" in devices that combine a standard magnetic material with a novel material known as a "topological insulator." The team's results show that such a scheme can be 10 times more efficient for controlling magnetic memory or logic than any other combination of materials measured to date.

The cellular process autophagy appears to not work properly, contributing to the destruction of insulin-producing beta cells - Enrique Rivero - People with Type 2 diabetes have an excess of a protein called islet amyloid polypeptide, or IAPP, and the accumulation of this protein is linked to the loss of insulin-producing pancreatic beta cells.

A team at Cornell and Brookhaven National Laboratory has discovered that previously observed density waves that seem to suppress superconductivity are linked to an electronic "broken symmetry," offering an important clue to why superconductivity doesn't happen at higher temperatures.
