Taking the twinkle out of the night sky

If you are like most people, you probably enjoy the twinkling of stars that blanket the sky on a clear summer night. If you are an astronomer, chances are you find it extremely annoying.

Transformation optics make a U-turn for the better

(PhysOrg.com) -- Berkeley researchers have combined the scientific fields of transformation optics and plasmonics to demonstrate that with only moderate modifications of the dielectric component of a metamaterial, the physical ...

New phenomenon found in internal waves

(PhysOrg.com) -- Internal waves -- huge but nearly invisible ripples that occur in the oceans, the atmosphere and stars -- can play an important role in climate change and other processes, but there is plenty about them that ...

Molecules could create tiny circuits on computer chips

(PhysOrg.com) -- As the features on computer chips become increasingly smaller, finding ways to fabricate the chips has become a big challenge. In a new study, researchers from MIT have demonstrated that certain molecules ...

What will the Large Hadron Collider reveal?

With its successful test run at the end of 2009, the Large Hadron Collider near Geneva, Switzerland, seized the world record for the highest-energy particle collisions created by mankind. We can now reflect on the next questions: ...

Caltech scientists film photons with electrons

(PhysOrg.com) -- Techniques recently invented by researchers at the California Institute of Technology -- which allow the real-time, real-space visualization of fleeting changes in the structure of nanoscale matter -- have ...

Compressing photonic signals for greater bandwidth

Cornell researchers have developed an ingenious method to time-compress optical signals. The process could enable optical communication systems to carry many more bits per second or could also be used to generate short bursts ...
