Scientists Study And Learn To Prevent Nanoparticle 'Merging'
Researchers at the US Department of Energy's Brookhaven National Laboratory have identified how billionth-of-a-meter sized metal particles -- gold-atom clusters within carbon-atom shells -- can mesh together to form larger particles and have also found a way to control this process. The results, published in the September 27, 2005, online edition of Nano Letters, may help scientists determine how these "nanoparticles,"which have unique physical, chemical, and electronic properties, could be incorporated into new technologies. Better Early Diagnosis Of Relapsed Prostate Cancer
Positron Emission Topography with choline demonstrates greater efficiency in the early diagnosis of relapsed prostate cancer with respect to other imaging techniques, according to a new study. Hubble Finds Mysterious Disk Of Blue Stars Around A Black Hole
Astronomers using the NASA/ESA Hubble Space Telescope have identified the source of a mysterious blue light surrounding a supermassive black hole in our neighbouring Andromeda Galaxy (M31). Though the light has puzzled astronomers for more than a decade, the new discovery makes the story even more mysterious. Deep In The Ocean, A Clam That Acts Like A Plant
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. Nearsighted Children May Benefit From Rigid Contact Lenses
New research suggests that rigid gas permeable contact lenses may help slow the progression of nearsightedness, or myopia, in young children. Internet May Aid In Treating Panic Sufferers
Internet-based treatments for sufferers of panic disorder may be just as effective as face-to-face methods, a study by Monash University researchers has found. Physicists Set 'Speed Limit' For Future Superconducting Magnet
The material currently used in magnetic resonance imaging machines -- a low-temperature superconducting alloy of niobium -- has been pushed almost as far as it can go, to around 21 Tesla. Now a team led Northwestern University researchers has identified a high-temperature superconductor -- called Bi-2212 -- as a material that might be suitable for the new wires needed to one day build the most powerful superconducting magnet in the world, a 30 Tesla magnet. Fake Tan, Real Tan
Scientists develop fake tanning lotions that will look more natural and help prevent skin cancer. By Elizabeth Svoboda. Cornell Web Site Will Aid Gulf Coast Recovery
A Web site being developed at Cornell University will give reconstruction workers and researchers access to detailed information on the status of critical infrastructure in communities along the Mississippi coast, based on data collected in the field and added to a Geographic Information Systems (GIS) database. Passport to Insecurity
Britain's high-tech passport is designed to frustrate terrorists and fraudsters. Now in the hands of 3 million citizens, it may not be so secure. In Beyond the Beyond.
