Advance makes MRI scans more than seven times faster
BERKELEY — An international team of physicists and neuroscientists has reported a breakthrough in magnetic resonance imaging that allows brain scans more than seven times faster than currently possible. In a paper that appeared Dec. 20 in the journal PLoS ONE , a University of California, Berkeley, physicist and colleagues from the University of Minnesota and Oxford University in the United Kingdom describe two improvements that allow full three-dimensional brain scans in less than half a second, instead of the typical 2 to 3 seconds.

New light shed on cosmic dark ages
New light shed on cosmic dark ages
Remnants of the first stars have helped astronomers get closer to unlocking the “dark ages” of the cosmos. A team of researchers from the University of Cambridge and California Institute of Technology are using light emitted from massive black holes called quasars to "light up" gases released by the early stars, which exploded billions of years ago.

World's smallest periodic table?
World’s smallest periodic table?
PA 364/10 Scientists at The University of Nottingham have written what they believe is the world's smallest periodic table — on the side of a human hair. The table is so small that a million of them could be replicated on a typical post-it note. Experts from the University's Nottingham Nanotechnology and Nanoscience Centre used a sophisticated combination of ion beam writer and electron microscope to carve the symbol of all 118 elements into the strand of hair taken from the head of Professor Martyn Poliakoff, an expert in Green Chemistry.

Cassini Marks Holidays With Dramatic Views of Rhea
PASADENA, Calif. Newly released for the holidays, images of Saturn's second largest moon Rhea obtained by NASA's Cassini spacecraft show dramatic views of fractures cutting through craters on the moon's surface, revealing a history of tectonic rumbling. The images are among the highest-resolution views ever obtained of Rhea.

The universe’s most massive stars can form in near isolation, new study finds
ANN ARBOR, Mich.—New observations by University of Michigan astronomers add weight to the theory that the most massive stars in the universe could form essentially anywhere, including in near isolation; they don't need a large stellar cluster nursery. This is the most detailed observational study to date of massive stars that appear (from the ground) to be alone.

Spinning information for better memory
The University of Sydney's Dr Dane McCamey and his international colleagues have demonstrated that the spin of atomic nuclei in silicon can store information for over one hundred seconds and, importantly, that this information can then be read out electrically - a critical step in linking the emerging field of spintronics with classical electronics.

Herschel looks back in time to see today's stars bursting into life
An international team of astronomers have presented the first conclusive evidence for a dramatic surge in star birth in a recently discovered population of massive galaxies in the early Universe. The scientists used the European Space Agency's Herschel Space Observatory, an infrared telescope with a mirror 3.5 m in diameter, launched in 2009.

Hot Plasma Explosions Inflate Saturn's Magnetic Field
Hot Plasma Explosions Inflate Saturn’s Magnetic Field
A new analysis based on data from NASA's Cassini spacecraft finds a causal link between mysterious, periodic signals from Saturn's magnetic field and explosions of hot ionized gas, known as plasma, around the planet. Scientists have found that enormous clouds of plasma periodically bloom around Saturn and move around the planet like an unbalanced load of laundry on spin cycle.

Qatar-Led International Team Finds Their First Alien World
Cambridge, MA - In an exciting example of international collaboration, a Qatar astronomer teamed with scientists at the Harvard-Smithsonian Center for Astrophysics (CfA) and other institutions to discover a new alien world. This "hot Jupiter," now named Qatar-1b, adds to the growing list of alien planets orbiting distant stars.

In the future: processing and memory on a single chip
Researchers have shown that a magnetically polarised current can be manipulated by electric fields. This important discovery opens up the prospect of simultaneously processing and storing data on electrons held in the molecular structure of computer chips - combining computer memory and processing power on the same chip.

’Black hole of evidence’ for motorcycle rider training
A review by experts from Sydney-based The George Institute for Global Health has revealed a startling lack of evidence of whether pre- and post-licence training is effective in reducing death and serious injury for motorcycle riders. Researchers from The George Institute analysed over 23 studies conducted from 1975 to the present day publishing their findings in The Cochrane Library .

Vibrating nanorods measure thin films for microcircuits
Vibrating nanorods measure thin films for microcircuits
A key step in many nanofabrication processes is to create thin films, sometimes only one molecule thick, by a method known as atomic layer deposition. Researchers at Cornell and Tel Aviv University have developed a new tool for nanofabricators to test the physical properties of such films. Ultrathin films are increasingly important in constructing microcircuits.

Project will monitor tremor activity beneath San Andreas Fault
BERKELEY — The Berkeley Seismological Laboratory will begin early next year to install earthquake detectors on the southern San Andreas Fault near the town of Cholame to study mysterious tremors discovered beneath the area. Tremors from deep underground have been detected in the area of Cholame, 32 kilometers southeast of Parkfield.

Black holes and warped space: New UK telescope shows off first images
This dramatic image is the first to be produced by e-MERLIN, a powerful new array of radio telescopes linked across the UK. Spearheaded by the University of Manchester's Jodrell Bank Observatory and funded by the Science and Technology Facilities Council, the e-MERLIN telescope will allow astronomers to address key questions relating to the origin and evolution of galaxies, stars and planets.

NASA's Spitzer Reveals First Carbon-Rich Planet
NASA’s Spitzer Reveals First Carbon-Rich Planet
PASADENA, Calif. Astronomers have discovered that a huge, searing-hot planet orbiting another star is loaded with an unusual amount of carbon. The planet, a gas giant named WASP-12b, is the first carbon-rich world ever observed. The discovery was made using NASA's Spitzer Space Telescope, along with previously published ground-based observations.

New Observations of Exploding Stars Reveal Pauses, Flickers and Flares not Reliably Seen Before
Astronomers have traced the waxing and waning light of exploding stars more closely than ever before and seen patterns that aren't yet accounted for in our current understanding of how these eruptions occur. A team led by Bernard Jackson, a solar physicist at the Center for Astrophysics and Space Sciences at the University of California, San Diego, developed the instrument that allowed the team to make such precise measurements.

Sneak Attacks from the Sun
Sneak Attacks from the Sun
Cambridge, MA - Our Sun can be a menace when it sends out powerful solar blasts of radiation towards the Earth. Astronomers keenly watch the Sun to learn more about what powers these solar eruptions, in hopes of being able to predict them. New research shows that one-third of the Sun's blasts are "sneak attacks" that may occur without warning.

Study showing that humans have some psychic powers caps Daryl Bem’s career
It took eight years and nine experiments with more 1,000 participants, but the results offer evidence that humans have some ability to anticipate the future. "Of the various forms of ESP or psi, as we call it, precognition has always most intrigued me because it's the most magical," said Daryl Bem, professor of psychology emeritus, whose study will be published in the American Psychological Association's Journal of Personality and Social Psychology sometime next year.
