Finding frugal aliens: 'Benford beacons' concept could refocus search for intelligent extraterrestrial life
UC Irvine astrophysicist Gregory Benford and his twin, James ― a fellow physicist specializing in high-powered microwave technology - believe there is, and their ideas are garnering attention.

Stingy aliens may call us on cheap rates only - New Scientist
aliens would choose to transmit at nearer to 10 gigahertz, as this makes it easier and cheaper to create a powerful beam.
Most SETI projects tune in to the "cosmic water hole" waveband between 1.42 and 1.72 gigahertz.

Heart of darkness could explain sun mysteries - New Scientist
Their simulations show that gravity would pull such dark particles to the centre of the sun, where they would absorb heat. Some of these dark matter particles would then carry this heat from the core to the surface, decreasing the core temperature

Our main conclusion demonstrates that both direct detection experiments and particle accelerators may be complemented by using the Sun as a probe for WIMP dark matter particles in the 5-50 GeV mass range.

IceCube spies unexplained pattern of cosmic rays
"IceCube was not built to look at cosmic rays. Cosmic rays are considered background," Abbasi says. "However, we have billions of events of background downward cosmic rays that ended up being very exciting."

Time to go atomic on space station - New Scientist
The experiment, called Atomic Clock Ensemble in Space (ACES), will be built by EADS Astrium and is scheduled to fly to the space station in 2014, the European Space Agency announced last week. It will keep track of time by measuring the frequency of microwaves absorbed by cooled caesium atoms.

"Heiner Klinkrad, head of ESA's space debris office at ESOC, said here July 21 that a post-event analysis showed that the Chinese stage probably would have collided with Envisat if the avoidance maneuver had not been done. Such maneuvers will not be possible once Envisat is retired. "
