In tiny supercooled clouds, physicists exchange light and matter
Physicists have for the first time stopped and extinguished a light pulse in one part of space and then revived it in a completely separate location. view more (2007-02-08)
Into the Epoch of Galaxy Formation
Current theories hypothesize that more than 80% of all stars ever formed were assembled in galaxies during the latter half of the elapsed lifetime of the Universe, i.e., during the past 7-8 billion years. view more (2000-02-17)
Tension in the nanoworld
A joint team of researchers at CIC nanoGUNE (San Sebastian, Spain) and the Max Planck Institutes of Biochemistry and Plasma Physics (Munich, Germany) report the non-invasive and nanoscale resolved infrared mapping of strain fields in semiconductors. view more (2009-01-26)
Turfgrass quality measurement improved with GreenSeeker sensor
To measure turfgrass performance, professionals have traditionally relied on trained human evaluators who provide visual assessments of turf quality. view more (2009-09-09)
How black is 'Super Black'?
Scientists at the National Physical Laboratory (NPL), Teddington, Middlesex, UK have good news for manufacturers and users across the optical instrumentation industry. Based on existing processes developed in the US and Japan, a team of researchers at NPL has developed a new technique for commercial manufacturing of ultra-black coatings, which... view more...

Quantum dot lasers — 1 dot makes all the difference
Physicists at the National Institute of Standards and Technology (NIST) and Stanford and Northwestern Universities have built micrometer-sized solid-state lasers in which a single quantum dot can play a dominant role in the device's performance. view more (2007-04-13)
Researchers approach quantum limit in third-order nonlinear light-light interaction
Researchers from Lehigh University and the Swiss Federal Institute of Technology in Zurich (ETH) have reported unprecedented nonlinear optical efficiency in some small organic molecules that makes the molecules potentially useful for optical computing, optical data processing, and optical telecommunication. view more (2005-11-15)
Transistor laser functions as non-linear electronic switch, processor
The transistor laser invented by scientists at the University of Illinois at Urbana-Champaign has now been found to possess fundamental non-linear characteristics that are new to a transistor and permit its use as a dual-input, dual-output, high-frequency signal processor. view more (2006-02-07)
Nowhere to hide -- new ultra-powerful microscope probes atomic world
A unique electron microscope, the first of its kind in the world, was unveiled yesterday at the STFC Daresbury Laboratory in Warrington. view more (2008-01-25)
Diatoms discovered to remove phosphorus from oceans
Scientists at the Georgia Institute of Technology have discovered a new way that phosphorus is naturally removed from the oceans -- its stored in diatoms. The discovery opens up a new realm of research into an element that's used for reproduction, energy storage and structural materials in every organism. The research appears in the May 2, 2008,... view more... (2008-05-05)
ORMatE returns to NRL after nearly 2 years in Earth orbit
Completing an 18-month mission orbiting the Earth more than 6,000 times on-orbit the International Space Station (ISS), the Optical Reflector Material Experiment (ORMatE-1) returns to Washington, D.C., to NRL's Electronics Science and Technology Division to begin experiment testing and analysis. view more (2009-09-30)
Results promising for computational quantum chemical methods for drug development
New research, led by a Virginia Tech chemist, may someday help natural-products chemists decrease by years the amount of time it takes for the development of certain types of medicinal drugs. view more (2007-12-21)
Moving a bit nearer to a quantum computer
By the time you`ve had your new computer for six months, much faster processors will already be on the market. But there is a limit to how fast conventional computers can become. This is because computers process information in a step-by-step fashion, carrying out each part of the process in turn. To make things work really fast, we need to build... view more... (2002-07-23)
