Finally a Gamma Ray Burster Shows Optical and X‐Ray Afterglows
We don't know whether the enigmatic gamma‐ray bursters are near or very far away. But now, at long last, we're beginning to accumulate vital clues at other wavelengths.
Can Phonons Squeeze their Way Into the Company of Photons?
The noise can be squeezed out of a light signal until it falls considerably below the quantum, or shot, limit. Now researchers are trying to use a similar trick to reduce the noise associated with phonons.
