New RFID technology helps robots find household objects

September 22, 2014 10:35 am | by Georgia Institute of Technology | Comments

A team of researchers has developed a new search algorithm that improves a robot’s ability to find and navigate to tagged objects. The team has implemented their system on a PR2 robot , allowing it to travel through a home and correctly locate....

Finding hints of gravitational waves in the stars

September 22, 2014 9:57 am | by EurekAlert! | Comments

Scientists have shown how gravitational waves—invisible ripples in the fabric of space and time that propagate through the universe—might be "seen" by looking at the stars. The new model proposes that a star that oscillates at the same frequency....

NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft successfully entered Mars’ orbit at 10:24 p.m. EDT Sunday, Sept. 21, where it now will prepare to study the Red Planet’s upper atmosphere as never done before. MAVEN is ...

Fracking’s environmental impacts scrutinised

September 21, 2014 3:30 am | by The University of Manchester | Comments

Greenhouse gas emissions from the production and use of shale gas would be comparable to conventional natural gas, but the controversial energy source actually faired better than renewables on some environmental impacts, according to new research....

Thermonuclear X-ray bursts on neutron stars set speed record

September 19, 2014 5:34 pm | by Georgia Institute of Technology | Comments

A new study of thermonuclear X-ray bursts on neutron stars reveals that, on very rare occasions, shells can be expelled at relativistic speeds - up to 30 percent of the speed of light. These velocities are the highest ever measured for a cosmic thermonuclear ...
