On Thursday, the Mitsubishi Electric Corporation unveiled its SeaAerial, which uses a column of seawater sprayed into the air to create a radio transceiver antenna.

Repeated attempts by Russian mission controllers have failed to rescue the stricken Progress 59 cargo spacecraft. It is now expected that the resupply ship will re-enter and burn up in Earth's atmosphere at some point over the next few weeks.

Though a long accepted tenet in physics, no experiment has ever directly observed the wave/particle duality of light. Now researchers at the École polytechnique fédérale de Lausanne (EPFL) in Switzerland claim to have captured a photograph of light as both waves and particles in the same image.
-
NASA mission controllers have successfully deployed the Soil Moisture Active Passive (SMAP) observatory’s reflector antenna, in what is an important step along the road towards the satellite becoming fully operational.
-
ScienceResearchers at Monash University in Australia claim to have produced nanoscale directional antennas that accurately focus light at the nanoscale and may provide the ultra-narrow beams needed for upcoming nanoelectromechanical systems (NEMS) and the eventual production of lab-on-a-chip devices.
-
Researchers have created a prototype optical antenna that is claimed to increase the intensity of emission from a nanorod light source by more than 115 times. This technique may offer the opportunity to replace power-hungry lasers with LEDs in short-range optical communications devices.
-
NASA's Dawn spacecraft has recovered from an unexpected phenomenon that resulted in the robotic explorer going into safe mode on September 11, mirroring a similar event that affected the spacecraft three years ago as it approached the protoplanet Vesta.
-
Researchers have developed a completely self-contained radio-on-a-chip device that comprises receiving and transmitting antennas and a central processor. Very cheap to manufacture and powered by ambient radio waves, it could give the "Internet of Things" a serious kick start.
-
The CSIRO's ASKAP radio telescope in Western Australia that will eventually form part of the upcoming Square Kilometer Array (SKA) recently began producing high-quality images of the sky using only six of its 36 antenna array.
-
BAE Systems and Queen Mary’s School of Electronic Engineering and Computer Science in London have come up with a flat lens that works like a conventional curved lens, yet without any reduction in bandwidth performance.
-
The Defence Advance Research Projects Agency (DARPA) plans to extend connectivity for forward military units with the use of small Wi-Fi-hosting drones, providing a reliable, mobile source of bandwidth to all echelons of the military on a scale unthinkable using current methods.
-
A new system called SARAS, which is a Spanish acronym for "Fast Acquisition of Satellites and Launchers," more than doubles the effective area of the receiving dish antenna, allowing signals from satellites to be acquired much faster.
