Harnessing new frequencies

Modern technology uses many frequencies of electromagnetic radiation for communication, including radio waves, TV signals, microwaves and visible light. Now, a University of Utah study shows how far-infrared light -- the last unexploited part of the electromagnetic spectrum -- could be harnessed to build much faster wireless communications and to detect concealed explosives and biological weapons.

1. 'Tunable' network features coordinated frequency combs
   05-10-2007 · EurekAlert!
   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 NIST. The flexible network design can simplify accurate comparisons of the latest atomic clocks operating at different frequencies and in different locations.

5. Atomic clock signals may be best shared by fiber-optics
   03-02-2007 · EurekAlert!
   Time and frequency information can be transferred between laboratories or to other users in several ways, often using the Global Positioning System (GPS), but today's best atomic clocks are so accurate that more stable methods are needed. The best solution may be to use lasers to transfer data over fiber-optic cables, according to scientists at JILA.

   Scientists have overcome two significant obstacles on the road to harnessing stem cells to build patches for damaged hearts. Presenting the research at a UK Stem Cell Initiative conference the researchers will explain how they have made significant progress in maturing beating heart cells derived from embryonic stem cells and in developing the physical scaffolding that would be needed to hold the patch in place in the heart in any future clinical application.
