| Liberating devices from their power cords Posted: 19 May 2014 09:25 AM PDT A new type of supercapacitor that can hold a charge when it takes a lickin' has been developed. It is the first "multi-functional" energy storage device that can operate while subject to realistic static and dynamic loads – advancing the day when everything from cell phones to electric vehicles will no longer need separate batteries.  |
| Earth organisms survive under Martian conditions: Methanogens stay alive in extreme heat and cold Posted: 19 May 2014 08:42 AM PDT New research suggests that methanogens -- among the simplest and oldest organisms on Earth -- could survive on Mars. Methanogens, microorganisms in the domain Archaea, use hydrogen as their energy source and carbon dioxide as their carbon source, to metabolize and produce methane, also known as natural gas. Methanogens live in swamps and marshes, but can also be found in the gut of cattle, termites and other herbivores as well as in dead and decaying matter.  |
| Posted: 18 May 2014 01:44 PM PDT Researchers have created an imaging system that reveals neural activity throughout the brains of living animals. This technique, the first that can generate 3-D movies of entire brains at the millisecond timescale, could help scientists discover how neuronal networks process sensory information and generate behavior.  |
| Emissions from forests influence very first stage of cloud formation Posted: 15 May 2014 12:41 PM PDT Clouds are the largest source of uncertainty in present climate models. Much of the uncertainty surrounding clouds' effect on climate stems from the complexity of cloud formation. New research sheds light on new particle formation -- the very first step of cloud formation. The findings closely match observations in the atmosphere and can help make climate prediction models more accurate.  |
