Mathematicians have finally laid to rest the legendary mystery surrounding an elusive group of numerical expressions known as the "mock theta functions."
Professor Sam Braunstein, of the University of York's Department of Computer Science, and Dr Arun Pati, of the Institute of Physics, Sainik School, Bhubaneswar, India, have established that quantum information cannot be 'hidden' in conventional ways, or in Braunstein's words, "quantum information can run but it can't hide."
This result gives a surprising new twist to one of the great mysteries about black holes.
A brush with a narcissist's inflated ego often leaves one reeling with resentment. Whether it is their constant need for attention or their unfounded sense of entitlement, we are often quick to attribute their shallow behavior to an unconscious self-loathing. However, new research from Keith Campbell at the University of Georgia, Jennifer Bosson at the University of South Florida and colleagues suggests that narcissists actually view themselves the same on the outside as on the inside.
New research published in the March issue of Psychological Science may help elucidate the relationship between religious indoctrination and violence, a topic that has gained renewed notoriety in the wake of the September 11th terrorist attacks. In the article, University of Michigan psychologist Brad Bushman and his colleagues suggest that scriptural violence sanctioned by God can increase aggression, especially in believers.Mentally insert whichever weapon or religious text you prefer if these examples offend you.
Comet McNaught, the Great Comet of 2007, has been delighting those who have seen it with the unaided eye as a spectacular display in the evening sky. Pushing ESO's New Technology Telescope to its limits, a team of European astronomers have obtained the first, and possibly unique, detailed observations of this object. Their images show spectacular jets of gas from the comet spiralling several thousands of kilometres into space, while the spectra reveal the presence of sodium in its atmosphere, something seen very rarely.
Do hard money contributions by interest groups to members of Congress contribute to better quality policy deliberations and outcomes in congressional committees? A new study conducted by political scientist Kevin M. Esterling (University of California, Riverside) finds that over the long term—regardless of the intent of such contributions—they tend to create incentives for members of Congress to enhance their analytical capacity for policymaking.
How does life survive in the black depths of the ocean? At the surface, sunlight allows green plants to "fix" carbon from the air to build their bodies. Around hydrothermal vents deep in the ocean live communities of giant clams with no gut and no functional digestive system, depending on symbiotic bacteria to use energy locked up in hydrogen sulfide to replace sunlight. Now, the genome of this symbiont has been completely sequenced and published in Science.
The safest possible future for advancing nanotechnology in a sustainable world can be reached by using green chemistry, says James E. Hutchison, a professor of chemistry at the University of Oregon.
“Around the world, there is a growing urgency about nanotechnology and its possible health and environmental impacts,” Hutchison said in his talk Sunday during a workshop at the annual meeting of the American Association for the Advancement of Science. “There is a concern that these issues will hinder commercialization of this industry.”
Silver-bearing ore found at the settlement founded by Christopher Columbus's second expedition was not mined in the Americas, new research reveals.Aerial view of La Isabela, the settlement established by Christopher Columbus's second expedition.

The ore that researchers excavated from the settlement, La Isabela, came from Spain, said Alyson Thibodeau, who analyzed the ores.
MOSCOW. (Yury Zaitsev for RIA Novosti) - Thirty years ago the Soviet government issued a resolution on setting up a space-based system to search for ships in distress (known by its initials in Russian, KOSPAS) anywhere in the world.
Researchers at the University of Warwick have found a direct connection between a nation’s overall happiness and its citizens’ blood pressure problems. Sweden, Denmark and the UK come top of this blood pressure based happiness league while Germany, Portugal and Finland come bottom.
The research by economists Professor Andrew Oswald of the Department of Economics at the University of Warwick and Professor David Blanchflower of Dartmouth College USA is about to be published by the National Bureau of Economic Research in Massachusetts.
Three hundred million years ago, Earth's climate shifted dramatically from icehouse to hothouse, with major environmental consequences. That shift was the result of both rising atmospheric carbon dioxide concentrations and the melting of vast ice sheets, new research by University of Michigan paleoclimatologist Christopher Poulsen shows.
In the digital age, organizing a photo collection has gone from bad to worse. The saying used to be that a picture is worth a thousand words. Now the question arises: what are a thousand pictures worth?
There is no such thing as a free lunch, some say, but they would be wrong. In fact, the entirety of the universe defies them. According to Stanford physics Professor Andrei Linde, one of the architects of the inflationary theory, our universe (and all the matter in it) was born out of a vacuum.
Nothing says romance like having your bone tissue extracted to show your love. But Biojewellry in the UK is doing exactly that.
The project is seeking couples who want to donate their bone cells - a couple having their wisdom teeth removed would be ideal. Their cells will be prepared and seeded onto a bioactive scaffold. This pioneering material encourages the cells to divide and grow rapidly in a laboratory environment, so that the scaffold disappears and is replaced by living bone tissue.
