| New kind of cosmic flash may reveal birth of a black hole Posted: 03 May 2013 08:04 PM PDT According to an astrophysicist, a new kind of cosmic flash may reveal something never seen before: the birth of a black hole.  |
| Hubble sees the remains of a star gone supernova Posted: 03 May 2013 12:15 PM PDT These delicate wisps of gas make up an object known as SNR B0519-69.0, or SNR 0519 for short. The thin, blood-red shells are actually the remnants from when an unstable progenitor star exploded violently as a supernova around 600 years ago. There are several types of supernovae, but for SNR 0519 the star that exploded is known to have been a white dwarf star -- a sun-like star in the final stages of its life.  |
| 'Going negative' pays for nanotubes Posted: 03 May 2013 08:47 AM PDT Researchers turn carbon nanotubes into negatively charged liquid crystals that could enhance the creation of fibers and films.  |
| How to frustrate a quantum magnet: 16 atomic ions simulate a quantum antiferromagnet Posted: 03 May 2013 07:50 AM PDT Frustration crops up throughout nature when conflicting constraints on a physical system compete with one another. The way nature resolves these conflicts often leads to exotic phases of matter that are poorly understood. In a new article, researchers describe how to frustrate a quantum magnet composed of sixteen atomic ions -- to date the largest ensemble of qubits to perform a simulation of quantum matter.  |
| Posted: 03 May 2013 06:49 AM PDT An undergraduate student has discovered that a process occurring in Saturn's magnetosphere is linked to the planet's seasons and changes with them, a finding that helps clarify the length of a Saturn day and could alter our understanding of the Earth's magnetosphere.  |
| Discovery of new gigantic swelling phenomenon of layered crystal driven by water Posted: 01 May 2013 11:41 AM PDT Scientists have discovered an intriguing phenomenon in which an inorganic layered crystal expanded and contracted by 100 times its original size in a few seconds in an aqueous solution, displaying a behavior similar to a living cell.  |
