Polarized particles join toolbox for building unique structures
Researchers at the University of Illinois at Urbana-Champaign have created polarized, spherical particles that spontaneously self-assemble into clusters with specific shapes and distributions of electric charge. view more (2006-10-13)
Goddard-Led GEMS Mission to Explore the Polarized Universe
An exciting new astrophysics mission led by NASA's Goddard Space Flight Center in Greenbelt, Md., will provide a revolutionary window into the universe. Named the Gravity and Extreme Magnetism Small Explorer (GEMS), the satellite will be the first to systematically measure the polarization of cosmic X-ray sources. view more (2009-08-05)
2 for 1: NIST design enables more cost-effective quantum key distribution
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a simpler and potentially lower-cost method for distributing strings of digits, or "keys," for use in quantum cryptography, the most secure method of transmitting data. view more (2008-05-30)
Argonne scientists pinpoint mechanism to increase magnetic response of ferromagnetic semiconductor
When squeezed, electrons increase their ability to move around. In compounds such as semiconductors and electrical insulators, such squeezing can dramatically change the electrical- and magnetic- properties. view more (2009-02-26)
Scientists link genetic pathway to development of hearing
Scientists are one step closer to understanding the genetic pathway involved in the development of hearing. view more (2005-08-19)
The Green (and blue, red, and white) lights of the future
A revolution in energy-efficient, environmentally-sound, and powerfully-flexible lighting is coming to businesses and homes, according to a paper in latest special energy issue of Optics Express, the Optical Society's (OSA) open-access journal. view more (2008-12-17)
UCF scientists control living cells with light; advances could enhance stem cells' power
University of Central Florida researchers have shown for the first time that light energy can gently guide and change the orientation of living cells within lab cultures. view more (2009-08-12)
Oosight microscope enables embryonic stem cell breakthrough
A noninvasive, polarized light microscope invented at the Marine Biological Laboratory (MBL) played a crucial role in a recent breakthrough in embryonic stem-cell research aimed at developing medical therapies. view more (2007-11-30)
Spin-polarized electrons on demand
Many hopes are pinned on spintronics. In the future it could replace electronics, which in the race to produce increasingly rapid computer components, must at sometime reach its limits. Different from electronics, where whole electrons are moved (the digital "one" means "an electron is present on the component", zero means... view more... (2009-01-22)

Argonne scientists peer into heart of compound that may detect chemical, biological weapons
A light-transmitting compound that could one day be used in high-efficiency fiber optics and in sensors to detect biological and chemical weapons at long distance almost went undiscovered by scientists because its structure was too difficult to examine. view more (2008-09-29)
University of Cincinnati researchers create all-electric spintronics
A multidisciplinary team of UC researchers is the first to find an innovative and novel way to control an electron's spin orientation using purely electrical means. view more (2009-10-28)
Polarization technique focuses limelight
An international team of astronomers, led by Professor Svetlana Berdyugina of ETH Zurich's Institute of Astronomy, has for the first time ever been able to detect and monitor the visible light that is scattered in the atmosphere of an exoplanet. view more (2007-12-27)
Physicists pin down spin of surface atoms
Scientists who dream of shrinking computers to the nanoscale look to atomic spin as one possible building block for both processor and memory, yet setting the spin of an atom, let alone measuring it, has been a challenge. view more (2007-09-13)
Livermore researchers find
With the exception of lasers and free-electron lasers, there hasn't been another fundamental way to produce coherent light for close to 50 years. view more (2006-01-16)
RIT Study Confirms Supermassive Black Holes Produce Powerful Galaxy-Shaping Winds
Supermassive black holes can produce powerful winds that shape a galaxy and determine their own growth, confirms a group of scientists from Rochester Institute of Technology. view more (2007-11-01)
Ambient light influences the evolution of colour signals
In light-contrasted ecosystems, ambient light and background colours influence the evolution of animal coloration. Because maximal conspicuousness is achieved for signals which are rich in the colours of ambient light but poorly reflected by background, different signals will be cryptic or conspicuous at different heights in tropical rainforest.... view more...

Magnetic Fields Play Larger Role in Star Formation than Previously Thought
he simple picture of star formation calls for giant clouds of gas and dust to collapse inward due to gravity, growing denser and hotter until igniting nuclear fusion. In reality, forces other than gravity also influence the birth of stars. New research shows that cosmic magnetic fields play a more important role in star formation than previously... view more...

Research breakthrough will lead to more accurate weather forecasts
More accurate global weather forecasts and a better understanding of climate change are in prospect thanks to a breakthrough by engineers at Queen's University Belfast's Institute of Electronics, Communications and Information Technology (ECIT). view more (2009-08-07)
Three-dimensional nanoimaging process provides detailed look at physical properties of liquid crystals
Charles Rosenblatt, professor of physics and macromolecular science at Case Western Reserve University, and his research group have developed a method of 3D optical imaging of anisotropic fluids such liquid crystals, with volumetric resolution one thousand times smaller than existing techniques. view more (2008-10-23)
