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

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.

Telling time on Saturn: Undergraduate student shows how planet's magnetosphere changes with the seasons

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.
