| Graphene produced using microorganisms from an ordinary river Posted: 21 Mar 2012 12:25 PM PDT Scientists have synthesized graphene by reducing graphene oxide using microorganisms extracted from a local river.  |
| Trees may play role in electrifying the atmosphere, study suggests Posted: 21 Mar 2012 07:55 AM PDT Plants have long been known as the lungs of the Earth, but a new finding has found they may also play a role in electrifying the atmosphere. Scientists have long-suspected an association between trees and electricity, but researchers in Australia think they may have finally discovered the link. The scientists ran experiments in six locations around Brisbane. They found the positive and negative ion concentrations in the air were twice as high in heavily wooded areas than in open grassy areas, such as parks.  |
| Jellyfish inspires latest ocean-powered robot Posted: 21 Mar 2012 06:41 AM PDT Researchers have created a robotic jellyfish, named Robojelly, which not only exhibits characteristics ideal to use in underwater search and rescue operations, but could, theoretically at least, never run out of energy thanks to it being fueled by hydrogen. Constructed from a set of smart materials, which have the ability to change shape or size as a result of a stimulus, and carbon nanotubes, Robojelly is able to mimic the natural movements of a jellyfish when placed in a water tank and is powered by chemical reactions taking place on its surface.  |
| Camera peers around corners: New imaging system uses opaque walls, doors or floors as 'mirrors' Posted: 20 Mar 2012 11:19 AM PDT A new imaging system could use opaque walls, doors or floors as "mirrors" to gather information about scenes outside its line of sight.  |
