| Fossilized conduits suggest water flowed beneath Martian surface Posted: 29 Jan 2013 09:19 AM PST Networks of narrow ridges found in impact craters on Mars appear to be the fossilized remnants of underground cracks through which water once flowed, according to a new analysis. The study bolsters the idea that the subsurface environment on Mars once had an active hydrology and could be a good place to search for evidence of past life. |
| Ants' behavior leads to research method for optimizing product development time, costs Posted: 29 Jan 2013 08:17 AM PST Trying to find just the right balance of time spent in meetings and time performing tasks is a tough problem for managers, but a researcher believes the behavior of ants may provide a useful lesson on how to do it. |
| New options for transparent contact electrodes Posted: 29 Jan 2013 07:02 AM PST Found in flat screens, solar modules, or in new organic light-emitting diode (LED) displays, transparent electrodes have become ubiquitous. Typically, they consist of metal oxides like In2O3, SnO2, ZnO and TiO2. But since raw materials like indium are becoming more and more costly, researchers have begun to look elsewhere for alternatives. |
| Posted: 29 Jan 2013 05:02 AM PST What can go wrong when computer simulations are applied outside their original context. In a new article scientists outline the many pitfalls associated with simulation methods such as Monte Carlo algorithms or other commonly used molecular dynamics approaches. |
| Posted: 29 Jan 2013 05:02 AM PST With minimal coding effort an Earth-observing satellite tool can be converted into a practical web-based application. In addition, a 3-D visualization technique has been developed. |
| Streaming video over temporary networks Posted: 29 Jan 2013 04:56 AM PST There are extra challenges when accidents occur in hard-to-reach locations such as in a tunnel or impassable mountain terrain where no stable computer networks are found. For the past ten years, however, technology for mobile ad hoc networks that enable rescue workers to communicate with one another or with a command control centre has been available. These networks configure themselves automatically among mobile devices located within a given geographic area. |
| Next generation solar cells: Trapping sunlight with microbeads Posted: 29 Jan 2013 04:56 AM PST In five to seven years, solar cells will have become much cheaper and only one-twentieth as thick as current solar cells. The trick is to deceive the sunlight with microbeads. |
