Dynamic Computer Simulations of Molecular Systems Essential for Quantum Mechanics

Because modern computers have to depict the real world with digital representations of numbers instead of physical analogues, to simulate the continuous passage of time they have to digitize time into small slices. This kind of simulation is essential in disciplines from medical and biological research, to new materials, to fundamental considerations of quantum mechanics, and the fact that it inevitably introduces errors is an ongoing problem for scientists.

Scientists Harness Spinmotive Force to Generate Electrical Current

Scientists are putting a new spin on their approach to generating electrical current by harnessing a recently identified electromotive force known as spinmotive force, which is related to the field of spintronics that addresses such challenges as improving data storage in computers.

Monster Charged Particle Geysers Shoot Out of Milky Way Galaxy

"Monster" outflows of charged particles from the centre of our Galaxy, stretching more than halfway across the sky, have been detected and mapped with CSIRO's 64-m Parkes radio telescope. Corresponding to the "Fermi Bubbles" found in 2010, the outflows were detected by astronomers from Australia, the USA, Italy and The Netherlands. The finding is reported in today's issue of Nature.

ALMA Telescope Reveals Key Stage in Birth of Giant Planets

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have seen a key stage in the birth of giant planets for the first time. Vast streams of gas are flowing across a gap in the disc of material around a young star. These are the first direct observations of such streams, which are expected to be created by giant planets guzzling gas as they grow. The result is published on 2 January 2013 in the journal Nature.

Mysterious Source of Incredible Energy Outflows from Centre of Galaxy

Enormous outflows of charged particles from the centre of our Galaxy, stretching more than halfway across the sky and moving at supersonic speeds, have been detected and mapped with CSIRO's 64-m Parkes radio telescope.

Quantum Technology Helps Demonstrate 'Secure Bit Commitment' Technology

Many scenarios in business and communication require that two parties share information without either being sure if they can trust the other. Examples include secure auctions and identification at ATM machines. Exploiting the strange properties of the quantum world could be the answer to dealing with such distrust: researchers at the Centre for Quantum Technologies (CQT) at the National University of Singapore have used the quantum properties of light to perform the world's first demonstration of a 'secure bit commitment' technology. The work is described in Nature Communications.

Supermassive Black Hole at Quasar’s Center Emits Record-Setting X-Ray Jet

Our understanding of the early universe has taken a small step forward thanks to the discovery of a new record-setting X-ray, emitting jet. The research was a collaboration of astronomers led by Teddy Cheung Ph.D. ’04, and included Professor of Astrophysics John Wardle, Doug Gobeille Ph.D. ’10 and four other scientists. It was detected with the Chandra X-Ray Observatory, and observed with the Hubble Space Telescope and with the radio antennas of the Very Large Array in New Mexico.

Physicist Describes New Mechanism for Magnetisation of the Universe

Magnets have practically become everyday objects. Earlier on, however, the universe consisted only of nonmagnetic elements and particles. Just how the magnetic forces came into existence has been researched by Prof. Dr. Reinhard Schlickeiser at the Institute of Theoretical Physics of the Ruhr-Universität Bochum. In the journal Physical Review Letters, he describes a new mechanism for the magnetisation of the universe even before the emergence of the first stars.

Cosmic High-Mass, High-Charged Particle Radiation Can Cause Cognitive Problems

As if space travel was not already filled with enough dangers, a new study out today in the journal PLOS ONE shows that cosmic radiation – which would bombard astronauts on deep space missions to places like Mars – could accelerate the onset of Alzheimer’s disease.

Swift's Ultraviolet/Optical Telescope Targets Galaxies Powered by Supermassive Black Holes

Of the three telescopes carried by NASA's Swift satellite, only one captures cosmic light at energies similar to those seen by the human eye. Although small by the standards of ground-based observatories, Swift's Ultraviolet/Optical Telescope (UVOT) plays a critical role in rapidly pinpointing the locations of gamma-ray bursts (GRBs), the brightest explosions in the cosmos.

Neutrinos May Explain Absence of Anti-Matter in the Universe

A collaboration with major participation by physicists at the University of Wisconsin-Madison has made a precise measurement of elusive, nearly massless particles, and obtained a crucial hint as to why the universe is dominated by matter, not by its close relative, anti-matter.
