Chameleon star baffles astronomers

Posted: 24 Jan 2013 03:34 PM PST

New observations of a pulsar challenge all proposed pulsar emissions theories, a new study reports. This reopens a decades-old debate about the nature of these bizarre stars.

NASA Super-TIGER balloon shatters flight record

Posted: 24 Jan 2013 01:34 PM PST

Flying high over Antarctica, a NASA long duration balloon has broken the record for longest flight by a balloon of its size. The record-breaking balloon, carrying the Super Trans-Iron Galactic Element Recorder (Super-TIGER) experiment, has been afloat for 46 days and is on its third orbit around the South Pole.

Liquid metal makes silicon crystals at record low temperatures

Posted: 24 Jan 2013 01:32 PM PST

A new way of making crystalline silicon could make this crucial ingredient of computers and solar cells much cheaper and greener.

Red explosions: Secret life of binary stars is revealed

Posted: 24 Jan 2013 12:08 PM PST

An astrophysicist has revealed the workings of a celestial event involving binary stars that produce an explosion so powerful its luminosity ranks close to that of a supernova, an exploding star.

Organic ferroelectric molecule shows promise for memory chips, sensors

Posted: 24 Jan 2013 12:07 PM PST

A cheap, flexible organic molecule could replace inorganic crystals as the working parts for memory chips, sensors and energy-harvesting systems.

Love triumphs over hate to make exotic new compound: Compound could be useful in batteries, semiconductors, memory devices

Posted: 24 Jan 2013 12:07 PM PST

A graduate student had a hunch for creating an exotic new chemical compound, and his idea that the force of love is stronger than hate proved correct. He and his colleagues are the first to permanently interlock two identical tetracationic rings that normally are repelled by each other. Many experts had said it couldn't be done. The new compound has attractive electronic characteristics and can be made quickly and inexpensively.

Proton size puzzle: Surprisingly small proton radius confirmed with laser spectroscopy of exotic hydrogen

Posted: 24 Jan 2013 11:07 AM PST

An international team of scientists confirms a surprisingly small proton radius with laser spectroscopy of exotic hydrogen.

3-D fireworks of a star: Astronomers reconstruct journey of emitted gas

Posted: 24 Jan 2013 09:34 AM PST

In 1901 the star GK Persei gave off a powerful explosion that has not stopped growing and astonishing ever since. Now astronomers have reconstructed the journey of the emitted gas in 3-D which, contrary to predictions, has hardly slowed down its speed of up to 1,000 km/s after all this time.

Liquid crystal's chaotic inner dynamics

Posted: 24 Jan 2013 06:21 AM PST

Scientists have unearthed a new dynamic process induced by strong electric fields in thin liquid crystal cells. Liquid crystal displays are ubiquitous. Now, physicists have demonstrated that the application of a very strong alternating electric field to thin liquid crystal cells leads to a new distinct dynamic effect in the response of the cells.

Revolutionary theory of dark matter

Posted: 24 Jan 2013 06:15 AM PST

The universe abounds with dark matter. Nobody knows what it consists of. Physicists in Norway have now come up with a mathematical explanation that could solve the mystery once and for all.
