| NASA's veteran Mars rover ready to start 10th year Posted: 22 Jan 2013 01:38 PM PST NASA's Mars Exploration Rover Opportunity, one of the twin rovers that bounced to airbag-cushioned safe landings on Mars nine years ago this week, is currently examining veined rocks on the rim of an ancient crater.  |
| Just add water: How scientists are using silicon to produce hydrogen on demand Posted: 22 Jan 2013 11:32 AM PST Super-small particles of silicon react with water to produce hydrogen almost instantaneously, without the need for light, heat or electricity, according to new research.  |
| New 2-D material for next generation high-speed electronics Posted: 22 Jan 2013 09:24 AM PST Scientists have produced a new two-dimensional material that could revolutionize the electronics market, making "nano" more than just a marketing term.  |
| Image sensors out of a spray can Posted: 22 Jan 2013 09:24 AM PST Researchers have developed a new generation of image sensors that are more sensitive to light than the conventional silicon versions, with the added bonus of being simple and cheap to produce. They consist of electrically conductive plastics, which are sprayed on to the sensor surface in an ultra-thin layer. The chemical composition of the polymer spray coating can be altered so that even the invisible range of the light spectrum can be captured.  |
| Hubble focuses on the 'Great Attractor' Posted: 22 Jan 2013 08:24 AM PST A busy patch of space has been captured in an image from the NASA/ESA Hubble Space Telescope. Scattered with many nearby stars, the field also has numerous galaxies in the background.  |
| Betelgeuse braces for a collision Posted: 22 Jan 2013 07:56 AM PST Multiple arcs are revealed around Betelgeuse, the nearest red supergiant star to Earth, in a new image from the European Space Agency's Herschel space observatory. The star and its arc-shaped shields could collide with an intriguing dusty 'wall' in 5000 years.  |
| Mars' Reull Vallis: A river ran through it Posted: 22 Jan 2013 07:50 AM PST The European Space Agency's Mars Express imaged the striking upper part of the Reull Vallis region of Mars with its high-resolution stereo camera last year. Reull Vallis, the river-like structure in these images, is believed to have formed when running water flowed in the distant martian past, cutting a steep-sided channel through the Promethei Terra Highlands before running on towards the floor of the vast Hellas basin.  |
| Analysis of fracking wastewater yields some surprises Posted: 22 Jan 2013 07:21 AM PST Hydraulically fractured natural gas wells are producing less wastewater per unit of gas recovered than conventional wells would. But the scale of fracking operations in the Marcellus shale region is so vast that the wastewater it produces threatens to overwhelm the region's wastewater disposal capacity, according to new analysis.  |
| Cross-arms could speed up connection of new electricity supplies Posted: 22 Jan 2013 07:14 AM PST A revolutionary device could dramatically increase the capacity of the UK's electricity network, enabling rapid increases in renewable generation and lower bills for consumers. Insulated Cross-arms have been installed on pylons in some of the most stark and remote areas of the UK to test their resistance to extreme weather and are also being tested for an eventual use with 400,000 volt systems at a coastal site in Scotland.  |
| New information on binding gold particles over metal oxide surfaces Posted: 22 Jan 2013 07:14 AM PST The strong binding of gold on electronically modified calcium oxide can now be understood in detail. In a computational study, researchers have shown how redox chemistry entirely determines the adsorption strength of gold on the modified oxide where one metal atom is replaced with molybdenum.  |
