| Properties of 'confined' water within single-walled carbon nanotube pores clarified Posted: 22 Jun 2011 01:23 PM PDT Water and ice may not be among the first things that come to mind when you think about single-walled carbon nanotubes, but a Japan-based research team hoping to get a clearer understanding of the phase behavior of confined water in the cylindrical pores of carbon nanotubes zeroed in on confined water's properties and made some surprising discoveries.  |
| Is Enceladus hiding saltwater ocean? Cassini captures ocean-like spray at Saturn's moon Posted: 22 Jun 2011 10:36 AM PDT NASA's Cassini spacecraft has discovered the best evidence yet for a large-scale saltwater reservoir beneath the icy crust of Saturn's moon Enceladus. The data came from the spacecraft's direct analysis of salt-rich ice grains close to the jets ejected from the moon.  |
| Pandora's cluster: A galactic crash investigation Posted: 22 Jun 2011 10:35 AM PDT A team of scientists has studied the galaxy cluster Abell 2744, nicknamed Pandora's Cluster. They have pieced together the cluster's complex and violent history using telescopes in space and on the ground, including the Hubble Space Telescope and ESO's Very Large Telescope. Abell 2744 seems to be the result of a simultaneous pile-up of at least four separate galaxy clusters and this complex collision has produced strange effects that have never been seen together before.  |
| Gold nanoparticles help earlier diagnosis of liver cancer Posted: 22 Jun 2011 09:57 AM PDT Medical researchers have devised a new technique to spot cancerous tumors in the liver as small as 5 millimeters. The technique, using gold nanoparticles, is the first to deploy metal nanoparticles as agents to enhance X-ray scattering of image tumor-like masses.  |
| Waste heat converted to electricity using new alloy Posted: 22 Jun 2011 09:57 AM PDT Engineering researchers have recently discovered a new alloy material that converts heat directly into electricity. This revolutionary energy conversion method is in the early stages of development, but it could have wide-sweeping impact on creating environmentally friendly electricity from waste heat sources.  |
| 'Super sand' for better purification of drinking water Posted: 22 Jun 2011 07:28 AM PDT Scientists have developed a way to transform ordinary sand -- a mainstay filter material used to purify drinking water throughout the world -- into a "super sand" with five times the filtering capacity of regular sand. The new material could be a low-cost boon for developing countries, where more than a billion people lack clean drinking water, according to a new article.  |
