Decision-making impairment appears greater in alcoholics with coexisting personality disorders
People make decisions all the time: they form preferences, take action, and evaluate outcomes, whether rewarding or aversive. Impaired decision making is regarded as one of the neurobehavioral hallmarks of addiction. view more (2006-09-25)
Cluster makes a shocking discovery
ESA's Cluster was in the right place and time to make a shocking discovery. The four spacecraft encountered a shock wave that kept breaking and reforming - predicted only in theory. view more (2007-05-15)
Cluster Quartet Probes the Secrets of the Black Aurora
Swedish and British researchers have used the European Space Agency`s Cluster spacecraft to unveil the mysteries of the "black aurora", a strange electrical phenomenon that generates dark, empty regions adjacent to the visible Northern and Southern Lights. The new results, to be announced today at a meeting of the American Geophysical Union in San... view more... (2001-12-10)
Ghostly glow reveals galaxy clusters in collision
A team of scientists, including astronomers from the Naval Research Laboratory (NRL), have detected long wavelength radio emission from a colliding, massive galaxy cluster which, surprisingly, is not detected at the shorter wavelengths typically seen in these objects. view more (2008-10-16)
NASA finds direct proof of dark matter
Dark matter and normal matter have been wrenched apart by the tremendous collision of two large clusters of galaxies. The discovery, using NASA's Chandra X-ray Observatory and other telescopes, gives direct evidence for the existence of dark matter. view more (2006-08-22)
Molecules on a string, and why size isn't the only thing that matters for data storage
Molecules of hydrogen are difficult to steer with electric fields because of the symmetrical way that charges are distributed within them. But now researchers at ETH Zurich have found a clever technique to get a grip on the molecules. view more (2009-09-15)
Location, location, location
As housing developments sprout across the United States, smart growth proponents have urged communities to cluster developments in concentrated pockets, instead of the more standard and familiar 'sprawl.' view more (2007-10-25)
Carnegie Mellon researchers save electricity with low-power processors and flash memory
Researchers at Carnegie Mellon University and Intel Labs Pittsburgh (ILP) have combined low-power, embedded processors typically used in netbooks with flash memory to create a server architecture that is fast, but far more energy efficient for data-intensive applications than the systems now used by major Internet services. view more (2009-10-15)
ESA's Cluster solved an auroral puzzle
ESA's four Cluster spacecraft have made a remarkable set of observations that has led to a breakthrough in understanding the origin of a peculiar and puzzling type of aurora. These aurorae - seen as bright spots in Earth's atmosphere and called 'dayside proton auroral spots' - occur when fractures appear in the Earth's magnetic field, allowing... view more... (2003-05-20)
Landscapes and human behavior
On Arizona State University's (ASU) Polytechnic campus, graduate student families in the cluster of six houses abutting lush lawns and ornamental bushes spend time together talking while their kids play outside. view more (2006-08-10)
Killer electrons in space are now less mysterious
A rare, timely conjunction of ground-based instrumentation and a dozen satellites has helped scientists better understand how electrons in space can turn into 'killers'. ESA's Cluster constellation has contributed crucially to the finding. view more (2007-07-27)
Largest ever survey of very distant galaxy clusters completed
An international team of researchers led by a UC Riverside astronomer has completed the largest ever survey designed to find very distant clusters of galaxies. view more (2009-07-01)
The Drifting Star
By studying in great detail the 'ringing' of a planet-harbouring star, a team of astronomers using ESO's 3.6-m telescope have shown that it must have drifted away from the metal-rich Hyades cluster. This discovery has implications for theories of star and planet formation, and for the dynamics of our Milky Way. view more (2008-04-16)
Stars stop forming when big galaxies collide
Astronomers studying new images of a nearby galaxy cluster have found evidence that high-speed collisions between large elliptical galaxies may prevent new stars from forming, according to a paper to be published in a November 2008 issue of The Astrophysical Journal Letters. view more (2008-10-08)
Cluster opens a new window on 'magnetic reconnection' in the near-Earth space
Plasma physicists have made an unprecedented measurement in their study of the Earth's magnetic field. Thanks to ESA's Cluster satellites they detected an electric field thought to be a key element in the process of 'magnetic reconnection'. view more (2007-03-13)
Researchers develop flood-tolerant California rice
Rice grown anywhere in the world soon could be made completely flood-tolerant because of new research by UC Riverside geneticists, done in collaboration with scientists at UC Davis and the International Rice Research Institute in the Philippines. view more (2006-08-23)
WHO 2003-2008: A Programme Of Quiet Thunder Takes Shape (p 179)
This week's editorial looks ahead to the future of WHO as Dr J W Lee is poised to take over as leader of the only global health agency from Gro Harlem Brundtland on July 21. Lee's priorities are discussed: 'The priority among priorities is HIV/AIDS. The phrase "3-by-5" peppers the language of Lee loyalists. His goal is to get 3 million... view more... (2003-07-16)
Researchers probe a DNA repair enzyme
U. of I. researchers have taken the first steps toward understanding how an enzyme repairs DNA. Enzymes called helicases play a key role in human health, according to Maria Spies, a University of Illinois biochemistry professor. view more (2008-02-19)
X-Ray Vision Of Violence In Interacting Galaxy Clusters
ROYAL ASTRONOMICAL SOCIETY PRESS NOTICE: Ongoing research by an international team of astronomers is providing new insights into cataclysmic cosmic collisions between galaxy clusters. view more (2005-03-31)
Neutron stars can be more massive, while black holes are more rare, Arecibo Observatory finds
Neutron stars and black holes aren't all they've been thought to be. In fact, neutron stars can be considerably more massive than previously believed, and it is more difficult to form black holes, according to new research developed by using the Arecibo Observatory in Arecibo, Puerto Rico. view more (2008-01-15)
