Conventional copper telephone lines struggle to meet this demand, and modern optical fiber networks connecting the homes of consumers to the network backbone are becoming necessary. Jing Zhang and co-workers at the ASTAR Institute of Microelectronics have now demonstrated a network scheme that considerably reduces the cost of fiber-optic installations and could make them more attractive for consumer use. http://phys.org/news217767874.html Physics Thu, 24 Feb 2011 11:04:45 EST news217767874 In a paradox typical of the quantum world, JILA scientists have eliminated collisions between atoms in an atomic clock by packing the atoms closer together.

At present, there are no good options for such people; the only treatment that reduces the symptoms of painful and very frequent urination, which can be debilitating and make it impossible to work, is an infusion of the drug lidocaine into the bladder through a catheter, but the treatment only provides brief relief and needs to be repeated frequently. http://phys.org/news212673821.html Medicine & Health Mon, 27 Dec 2010 12:04:13 EST news212673821 A team of scientists and engineers at NASA's Jet Propulsion Laboratory has brought the world one step closer to "hearing" gravitational waves -- ripples in space and time predicted by Albert Einstein in the early 20th century. http://phys.org/news209810996.html Physics Wed, 24 Nov 2010 08:50:16 EST news209810996 Laser uses relativistic effects to turn otherwise opaque plasma transparent, creating an ultra-fast optical switch useful in next-generation particle accelerators. http://phys.org/news208417052.html Physics Mon, 08 Nov 2010 05:37:43 EST news208417052 Scientists know how gravity works at big distances -- the inter-planetary or inter-stellar range -- but does it work the same way at the inter-atomic range? http://phys.org/news206200253.html Physics Wed, 13 Oct 2010 14:52:31 EST news206200253 (PhysOrg.com) -- As we strive to find sources of alternative energy, a number of researchers continue to look to what we consider the ultimate in renewable energy -- the sun.
