'Tunable' Network Features Coordinated Frequency Combs PhotonicsOnline
A super stable fiber-optic network that can be tuned across a range of visible and near-infrared frequencies while synchronizing the oscillations of light waves from different sources has been demonstrated at the National Institute of Standards and Technology (NIST). The flexible network design can simplify accurate comparisons of the latest atomic clocks operating at different frequencies and in
Transferring spin polarization from a gas to a solid PhysOrg
Some time ago, scientists learned to polarize noble gases so that when they were inhaled, an MRI machine could take pictures of the lungs. But if other types of elements could be polarized as well, the potential benefits to the medical community could be even greater.

Hyper-accurate Clocks: The Beating Heart Of Galileo Science Daily
Travellers have relied on accurate timekeeping for navigation since the development of the marine chronometer in the eighteenth century. Galileo, Europe's twenty-first century navigation system, also relies on clocks -- but they are millions of times more accurate than those earlier timepieces.
