| New nano-material combinations produce leap in infrared technology Posted: 14 Feb 2012 11:53 AM PST Researchers are using new combinations of nano-materials to produce advances in infrared photodetection technology.  |
| Shear stiffness and friction mechanics of single-layer graphene measured for the first time Posted: 14 Feb 2012 09:18 AM PST Researchers have measured and identified for the first time the stress and strain shear modulus and internal friction of graphene sheets.  |
| The indiscretions of a champagne bubble paparazzi Posted: 14 Feb 2012 07:09 AM PST The innermost secrets of champagne bubbles are about to be unveiled by a scientist tackling champagne bubbles from both a physics and a chemistry perspective. To understand what appears to be a harmless phenomenon such as the fizz in champagne, the author studied the role of the carbon dioxide throughout its journey from the bottle to the glass.  |
| 'Invisibility' cloak could protect buildings from earthquakes Posted: 14 Feb 2012 07:08 AM PST Mathematicians have developed the theory for a Harry Potter style 'cloaking' device which could protect buildings from earthquakes. Scientists have been working on the theory of invisibility cloaks which, until recently, have been merely the subject of science fiction. In recent times, however, scientists have been getting close to achieving 'cloaking' in a variety of contexts. The new work focuses on the theory of cloaking devices which could eventually help to protect buildings and structures from vibrations and natural disasters such as earthquakes.  |
| Globular clusters: Survivors of a 13-billion-year-old massacre Posted: 14 Feb 2012 07:08 AM PST Our Milky Way galaxy is surrounded by some 200 compact groups of stars, containing up to a million stars each. At 13 billion years of age, these globular clusters are almost as old as the universe itself and were born when the first generations of stars and galaxies formed. Now astronomers have conducted a novel type of computer simulation that looked at how they were born -- and they find that these giant clusters of stars are the only survivors of a 13-billion-year-old massacre that destroyed many of their smaller siblings.  |
