| Ultra-thin wires for quantum computing Posted: 17 Jun 2014 08:18 AM PDT Take a fine strand of silica fiber, attach it at each end to a slow-turning motor, torture it over a flame until it nearly reaches its melting point and then pull it apart. The middle will thin out like taffy until it is less than half a micron across, and that, according to researchers, is how you fabricate ultrahigh transmission optical nanofibers, a potential component for future quantum information devices.  |
| Strange physics turns off laser Posted: 17 Jun 2014 07:29 AM PDT Inspired by anomalies that arise in certain mathematical equations, researchers have demonstrated a laser system that paradoxically turns off when more power is added rather than becoming continuously brighter. The findings could lead to new ways to manipulate the interaction of electronics and light, an important tool in modern communications networks and high-speed information processing.  |
| The games genes play: Algorithm helps explain sex in evolution Posted: 16 Jun 2014 12:15 PM PDT Computer theorists have identified an algorithm to describe the strategy used by genes during sexual recombination. In doing so, they address the dueling evolutionary forces of survival of the fittest and of diversity. "The key to this work is the making of a connection between three theoretical fields: algorithms, game theory and evolutionary theory," said one researcher. "This new bridge is an uncommon advance that opens up possibilities for cross-fertilization between the fields in the future."  |
| Computation leads to better understanding of influenza virus replication Posted: 16 Jun 2014 12:13 PM PDT Computer simulations that reveal a key mechanism in the replication process of influenza A may help defend against future deadly pandemics. Treating influenza relies on drugs that are becoming less and less effective due to viral evolution. But scientists have published computational results that may give drug designers the insight they need to develop the next generation of effective influenza treatment.  |
