Airbus confident of avoiding Boeing battery issue

January 17, 2013 4:47 pm | by CARLO PIOVANO - Associated Press - Associated Press | News | Comments

Airbus said it was confident its planes would not encounter the same technical problems afflicting archrival Boeing's 787s, even though they use the same kind of batteries that have this week raised security concerns. The company may nevertheless be affected eventually, experts say. If investigations show that authorities had approved parts for the 787 that turned out to be deficient, Airbus may face tougher tests when it tries to launch a new plane this year.

Atom optics to help detect the imperceptible

October 22, 2012 8:43 am | by Lori Keesey | News | Comments

Predicted by Albert Einstein's general theory of relativity, the waves occur when massive celestial objects move and disrupt the fabric of space-time. But by the time these waves reach Earth, they are so weak that the planet expands and contracts less than an atom in response. No instrument or observatory has ever directly detected them. A pioneering technology capable of atomic-level precision is now being developed to detect what so far has remained imperceptible.
