LSU professor resolves Einstein's twin paradox
Subhash Kak, Delaune Distinguished Professor of Electrical and Computer Engineering at LSU, recently resolved the twin paradox, known as one of the most enduring puzzles of modern-day physics. view more (2007-02-15)
Overbearing colored light may reveal a second mechanism by which birds interpret magnetic signals
Magnetic orientation is critical to the migratory success of many bird species. By studying the influence of light on the ability of migratory birds to orient to magnetic signals, researchers have found clues to suggest that birds' orientation abilities may be more complex than previously thought. view more (2005-08-23)
Seeing magnetic fields
It has long been known that migratory birds can make use of the earth's magnetic fields to navigate. Birds read the angle that magnetic fields create on the ground and thereby determine how far north or south they are of the magnetic equator and the magnetic pole. But how do they do this? Is there some unknown "magnetic sense"? It seems... view more... (2004-02-23)
A New Method For Assessing Neurological Development Of Fetuses? (p 779)
A preliminary study in this week's issue of THE LANCET outlines how light-emitting technology could help in the future assessment of fetal neurological development. There have been only a few studies of visual-evoked response in human fetuses, and all have focused on general changes such as heart rate, body movements, and eye movements. Curtis... view more...

Sacred constant might be changing
Physical constants are one of the cornerstones of physics - sacred numbers which we know to be fixed - but what if some of these constants are changing? Speaking at the Institute of Physics conference Physics 2005, Dr Michael Murphy of Cambridge University will discuss the "fine structure constant" - one of the critical numbers in the... view more...

Researchers discover mechanism that helps humans see in bright and low light
Ever wonder how your eyes adjust during a blackout? When we go from light to near total darkness, cells in the retina must quickly adjust. Vision scientists at Washington University School of Medicine in St. Louis have identified an intricate process that allows the human eye to adapt to darkness very quickly. The same process also allows the eye... view more... (2009-10-14)
Born under the sun: UV light and the origin of life
Early evolution of life as we know it may have depended on DNA's ability to absorb UV light. This insight into the early moments of life on Earth comes from research published today in the journal BMC Evolutionary Biology. The research fills in one of the major gaps in our understanding about the origins of life: how single molecules were able to... view more... (2003-05-27)
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)
What scientists know about jewel beetle shimmer
"Jewel beetles" are widely known for their glossy external skeletons that appear to change colors as the angle of view changes. view more (2009-07-24)
Scientists shed light on the mystery of photosynthesis
Scientists at the University of Sheffield are part of an international team that has become the first to successfully discover how the component parts of photosynthesis fit together within the cell membrane. In a paper, The native architecture of a photosynthetic membrane, published in Nature on 26 August 2004, they describe how the configuration... view more... (2004-08-25)
Driven to distraction? Taking your mind off a decision can help
Remember when the answer to a big question came to you in the shower? Is "sleep on it" really good advice for someone making a big decision? A new study Journal of Consumer Research examines the way distraction affects consumers' product decisions. view more (2009-04-21)
Antarctic plants repair themselves
Dutch researchers funded by NWO have studied the effects of the hole in the ozone layer on the vegetation in Antarctica. The repair mechanisms of lichens and mosses appear to be effective even at low temperatures. Nevertheless, the ecology of the Antarctic is still under threat. The rise in temperature caused by the greenhouse effect is doing... view more... (2001-11-26)
New technology will allow for flexible television and computer screens
Organic light emitting diodes (OLED) are the technology used in making light emitting fabrics used in cell phones and televisions. view more (2006-05-12)
Nanoscience Study Shows That Quantum Dots "Talk"
Scientists who hope to use quantum dots as the building blocks for the next generation of computers have found a way to make these artificial atoms communicate. view more (2006-02-22)
Lighting up paper
Researchers have developed a sophisticated way of measuring the print quality of paper. The work, published today in the Institute of Physics journal, Measurement Science and Technology, describes how Jari Palviainen and colleagues at the Universities of Joensuu and Oulu in Finland, use what is known as a diffractive optical element-based sensor... view more...

Fishing in the dark
Nanotechnology is a relatively new scientific field that holds immense promise for the future. A nanometer is one millionth of a millimeter, and nanoparticles form the basis of completely new materials for pharmaceutical, cosmetic, electronic and optical applications. The size and structure of the particles are decisive in regulating the optical,... view more... (1999-09-03)
Light-induced hormone surge points to benefits of light therapy
A report in the November Cell Metabolism reveals powerful effects of light on the adrenal glands, a finding that might explain the broad benefits of bright light therapy for a variety of conditions, including sleep and depressive disorders, according to researchers. view more (2005-11-09)
Research project into Borna Disease Virus
Research being conducted at the University of Northumbria at Newcastle aims to throw light on a virus which could be at the root of many psychological illnesses. view more (1999-07-20)
A Colorful Approach to Solar Energy
Revisiting a once-abandoned technique, engineers at the Massachusetts Institute of Technology (MIT) have successfully created a sophisticated, yet affordable, method to turn ordinary glass into a high-tech solar concentrator. view more (2008-07-11)
Searching the heavens
A new space mission, due to launch this month, is going to shed light on some of the most extreme astrophysical processes in nature - including pulsars, remnants of supernovae, and supermassive black holes. view more (2008-05-01)
