| Advance brings 'hyperbolic metamaterials' closer to reality Posted: 14 May 2014 10:34 AM PDT Researchers have taken a step toward practical applications for 'hyperbolic metamaterials,' ultra-thin crystalline films that could bring optical advances including powerful microscopes, quantum computers and high-performance solar cells. |
| Quantum tunneling and the Aharonov-Bohm effect Posted: 14 May 2014 07:03 AM PDT Although quantum tunneling has been observed on large scales, no one has yet actually measured the tunneling of a single particle until now. Physicists report using an ion trap system to observe the Aharonov-Bohm effect with quantum tunneling. The AB effect demonstrates that a magnetic field inside a confined region can have a measureable impact on a charged particle which never traveled inside the region. |
| @millennials wary of @twitter, #MSU study finds Posted: 14 May 2014 07:03 AM PDT A new study indicates young adults have a healthy mistrust of the information they read on Twitter. Nearly anyone can start a Twitter account and post 140 characters of information at a time, bogus or not, a fact the study's participants seemed to grasp, according to the author of a recent study. |
| Strongly interacting electrons in wacky oxide synchronize to compute like the brain Posted: 14 May 2014 05:43 AM PDT A new type of computing architecture that stores information in the frequencies and phases of periodic signals could work more like the human brain to do computing using a fraction of the energy of today's computers. |
| In the age of open science, repurposing, reproducing research pose challenges Posted: 12 May 2014 11:22 AM PDT Growing numbers of researchers are making the data underlying their publications freely available online, largely in response to data sharing policies at journals and funding agencies. But in the age of open science, improving access is one thing, repurposing and reproducing research is another. Researchers experienced this firsthand when they tried to answer a seemingly simple question: what percentage of plants in the world are woody? |
