Testing the symmetry of space-time by means of atomic clocks

In his Special Theory of Relativity, Einstein formulated the hypothesis according to which the speed of light is always the same, no matter what the conditions are. It may, however, be possible that—according to theoretical ...

Quantum computers may have higher 'speed limits' than thought

How fast will a quantum computer be able to calculate? While fully functional versions of these long-sought technological marvels have yet to be built, one theorist at the National Institute of Standards and Technology (NIST) ...

Researchers determine key element in circadian clock speed

In a discovery that may lead to new treatments for sleep disorders, jet lag and other health problems tied to circadian rhythms, researchers at Dartmouth's Geisel School of Medicine have identified a determinant of the circadian ...

How to test the twin paradox without using a spaceship

Forget about anti-ageing creams and hair treatments. If you want to stay young, get a fast spaceship. That is what Einstein's Theory of Relativity predicted a century ago, and it is commonly known as "twin paradox".

Our devices will spin denser webs of data in 2010s

(AP) -- Ten years ago, we would have been blown away by a cell phone with far more computing power and memory than the average PC had in 1999, along with a built-in camera and programs to manage every aspect of our lives. ...

New 167-processor chip is super-fast, ultra energy-efficient

A new, extremely energy-efficient processor chip that provides breakthrough speeds for a variety of computing tasks has been designed by a group at the University of California, Davis. The chip, dubbed AsAP, is ultra-small, ...
