| Posted: 07 Sep 2011 01:39 PM PDT NASA's Solar Dynamics Observatory, which is carrying a suite of instruments, has provided scientists with new information that energy from some solar flares is stronger and lasts longer than previously thought.  |
| Nanosensors made from DNA may light path to new cancer tests and drugs Posted: 07 Sep 2011 10:21 AM PDT Sensors made from custom DNA molecules could be used to personalize cancer treatments and monitor the quality of stem cells, according to new research.  |
| New record for measurement of atomic lifetime Posted: 07 Sep 2011 09:43 AM PDT Researchers in Denmark have measured the lifetime of an extremely stable energy level of magnesium atoms with great precision. Magnesium atoms are used in research with ultra-precise atomic clocks. The new measurements show a lifetime of 2050 seconds, which corresponds to approximately one half hour. This is the longest lifetime ever measured in a laboratory.  |
| Researchers power line-voltage light bulb with nanotube wire Posted: 07 Sep 2011 07:47 AM PDT Cables made of carbon nanotubes are inching toward electrical conductivities seen in metal wires, and that may light up interest among a range of industries.  |
| New type of solar cell retains high efficiency for long periods Posted: 07 Sep 2011 07:46 AM PDT Scientists are reporting development of a new genre of an electrolyte system for solar cells that breaks the double-digit barrier in the efficiency with which the devices convert sunlight into electricity.  |
| Innovative superconductor fibers carry 40 times more electricity Posted: 07 Sep 2011 04:59 AM PDT Researchers in Israel have developed superconducting wires made of single sapphire crystals that can be used in high-powered cables. They take up much less space and conduct energy far more efficiently than current superconductor technologies -- and have the potential to revolutionize energy transfer.  |
| Nanoscale spin waves can replace microwaves Posted: 07 Sep 2011 04:57 AM PDT Scientists have now demonstrated that theories about nanoscale spin waves agree with observations. This opens the way to replacing microwave technology in many applications, such as mobile phones and wireless networks, by components that are much smaller, cheaper, and that require less resources.  |
