 Washington DC (SPX) Aug 25, 2009 
Does an exciting but controversial new model of quantum gravity reproduce Einstein's theory of general relativity? Scientists at Texas A and M University in the US explore this question in a paper appearing in Physical Review Letters and highlighted with a Viewpoint in the August 24th issue of Physics. "If it ain't broke, don't fix it," sums up fairly well how many scientists have viewed ... read more 
Tempe AZ (SPX) Aug 25, 2009Astronomers have been mining a mother lode of astronomical data from The University of Arizona's Catalina Sky Survey and finding more "optical transients" than they can characterize during the past 17 months. They have found more than 700 unique "optical transients," or objects that change brightness on time scales of minutes to years. They've also found 177 supernovae. That's more ... more

Hilo HI (SPX) Aug 24, 2009Old stars are keys to understanding the nature of the first stars and the earliest stages of the formation of the universe. Observations with the Subaru Telescope, fitted with its High Dispersion Spectrograph (HDS), have yielded data about the chemical composition of an old, bright star - BD+44 493 - that shed light on how the early stars may have developed during the infancy of the universe. ... more 
Hanover NH (SPX) Aug 24, 2009Despite their popularity in the science fiction genre, there is much to be learned about black holes, the mysterious regions in space once thought to be absent of light. In a paper published in the Physical Review Letters, the flagship journal of the American Physical Society, Dartmouth researchers propose a new way of creating a reproduction black hole in the laboratory on a much-tinier scale ... more  
Los Angeles CA (SPX) Aug 21, 2009Humans might not be walking on Earth today if not for the ancient fusing of two microscopic, single-celled organisms called prokaryotes, NASA-funded research has found. By comparing proteins present in more than 3000 different prokaryotes - a type of single-celled organism without a nucleus - molecular biologist James A. Lake from the University of California at Los Angeles' Center for ... more |

Pasadena CA (JPL) Aug 20, 2009A decade ago, NASA's Cassini spacecraft flew past Earth at a distance of 1,171 kilometers (727 miles) on its way to an appointment with the solar system's second largest occupant - Saturn. Launched in October of 1997, Cassini required a grand total of four planetary flybys to provide the gravity boost it needed to get to the ringed world. A gravity boost uses a planet's mass and orbi ... more  
Garching, Germany (ESO) Aug 20, 2009New images released by ESO delve into the heart of a cosmic cloud, called RCW 38, crowded with budding stars and planetary systems. There, young, titanic stars bombard fledgling suns and planets with powerful winds and blazing light, helped in their devastating task by short-lived, massive stars that explode as supernovae. In some cases, this energetic onslaught cooks away the matter that may ev ... more  
London UK (SPX) Aug 20, 2009UK scientists are helping us edge ever closer to finding the mysterious, theorized ripples in the fabric of space-time (known as gravitational waves) with the production of 25 new assemblies for the LIGO facility - a network of detectors designed to search for these elusive waves. Funded by the US National Science Foundation (NSF), LIGO also allows us to look inside the most violent events ... more |
