    A mysterious spiral of light has appeared in northern Norway one day before President Obama arrives to give his Nobel Peace Prize acceptance speech in Oslo. The spiral has baffled experts who do not believe it is related to the Aurora Borealis. Speculation that it is a rocket launched by the Russian Northern Fleet has been denied by Russian authorities. Similarly the Norwegian military has claimed no knowledge of any rocket launches in the area. There has been speculation that it may be some exotic weapon system, the opening of a space-time portal, or even UFO activity. Obama’s arrival in...

    LONDON (Reuters) – The amazing eyes of a giant shrimp living on Australia's Great Barrier Reef could hold the key to developing a new type of super high-quality DVD player, British scientists said on Sunday. Mantis shrimps, dubbed "thumb splitters" by divers because of their vicious claws, have the most complex eyes in the animal kingdom. They can see in 12 primary colors, four times as many as humans, and can also detect different kinds of light polarization -- the direction of oscillation in light waves.

    Increasing energy demands and concerns about global warming mean that the sun is an important inexhaustible and clean energy source. Dye sensitised solar cells (DSSCs) have proved to be a highly efficient and low-cost option for conversion of sunlight to energy. Ruthenium dye photosensitisers have given the highest power conversion efficiency in the past but they are not very environmentally friendly and supply is limited, explains Eric Diau at the National Chiao Tung University, Hsinchu, Taiwan. Diau and his team took inspiration from nature by developing a dye based on porphyrin - a component of chlorophyll, which gives plants their green...

    An electromagnetic "black holeMovie Camera" that sucks in surrounding light has been built for the first time. The device, which works at microwave frequencies, may soon be extended to trap visible light, leading to an entirely new way of harvesting solar energy to generate electricity. A theoretical design for a table-top black hole to trap light was proposed in a paper published earlier this year by Evgenii Narimanov and Alexander Kildishev of Purdue University in West Lafayette, Indiana. Their idea was to mimic the properties of a cosmological black hole, whose intense gravity bends the surrounding space-time, causing any nearby...

    When a person thinks about light, usually the first thing that will come to mind is the sun. We have been taught that the sun is the center of the solar system and thus it is the light of the world. This ball of fire that life on earth depends upon, is so massive in size that it contains 99.85% of all the matter in the Solar System, or 332,800 times that of earth. The distance from earth to the sun is 93,000,000 miles, which would take you 71 years to travel going 150 mph. The sun creates energy...

This reminds us of the darkness that came over the land when Christ was hanging on the cross, the great darkness that occurred when the author of life was put to death. And then his lifeless body was placed in the tomb, and night fell, and all was darkness and shadows. The loud noise at the...

As I pointed out in the interview, the rate of economic contraction will slow from the -6% of the first quarter to a figure closer to -2%. And next year the economic recovery will be so weak--growth below 1% and the unemployment rate peaking at 10%--that it will still feel like a recession even if we may be technically out of it.

    God is light; in Him there is no darkness at all. 1 John 1:5 God is light but He is much more than that. In fact if you were to combine all of the attributes that we equate God (love, omnipotent, omniscient, wise, etc), He would still be more than all of that. But light is one of those characteristics that helps to reveal who we are as his Creation. When you shine pure light anywhere, there is no place to hide. The bigger and brighter the light source, the fewer places there are to shield ourselves. And yet, that's...

    Throughout war, disaster and recession, it has kept Britain illuminated for more than 120 years. But the traditional incandescent lightbulb is finally being switched off for the last time. Retailers have stopped replenishing stocks of conventional 100watt bulbs and will have run out within weeks. The voluntary withdrawal – part of a Government campaign to force people into buying low-energy fluorescent bulbs – follows the scrapping of the 150w bulb last year. The move has angered medical charities who say the low-energy alternatives can trigger a host of ailments, including migraines, epilepsy and skin rashes. The lightbulb revolution was first...

    The story of Western architecture is one of darkness giving way to light. Europe's dour medieval fortresses were replaced by airy Gothic structures and for the modernists, light was an end in itself. Has this tale run its course? From the beginning, architecture has been embarked on a journey to the light. That we have arrived is something we now take for granted. But it wasn't always thus. Indeed, of all the elements that comprise architecture, light was historically the most elusive. For millennia, we lived in shadow. Anyone who has wandered through those 1,000-year-old Romanesque churches around Barcelona in...

Now, another idea initially dismissed as nutty is gaining acceptance: the graveyard shift might increase your cancer risk. Next month, the International Agency for Research on Cancer, the cancer arm of the World Health Organization, will classify shift work as a "probable" carcinogen. That will put shift work in the same category as cancer-causing agents like anabolic steroids, ultraviolet radiation, and diesel engine exhaust. If the shift work theory proves correct, millions of people worldwide could be affected. Experts estimate that nearly 20 percent of...

    If U.S. lawmakers have their way, the lights may soon go out on Thomas Edison's greatest invention -- the incandescent light bulb. The 19th-century inventor brought illumination to the world's fingertips, but according to Congress, his invention isn't efficient enough for an age anxious about energy supplies. "Only 10% of the power used by today's incandescent bulbs is emitted as light, while the other 90% is released as heat," Rep. Jane Harman, D-Calif., said when she introduced her legislation to ban standard light bulbs. To eliminate this waste, Harman has proposed legislation that would effectively eliminate incandescent light bulbs from...

According to Einstein's special theory of relativity, it would require an infinite amount of energy to propel an object at more than 186,000 miles per second. However, Dr Gunter Nimtz and Dr Alfons Stahlhofen, of the University of Koblenz, say they may have breached a key tenet of that theory. The pair say they have conducted an experiment in which microwave photons - energetic packets of light - travelled "instantaneously" between a pair of...

    Increasingly, physicists are constructing materials that bend light the “wrong” way, an optical trick that could lead to sharper-than-ever lenses or maybe even make objects disappear. Last October, scientists at Duke demonstrated a working cloaking device, hiding whatever was placed inside, although it worked only for microwaves. In the experiment, a beam of microwave light split in two as it flowed around a specially designed cylinder and then almost seamlessly merged back together on the other side. That meant that an object placed inside the cylinder was effectively invisible. No light waves bounced off the object, and someone looking at...

    Capitol Weekly ^ | 5/31/07 | John Howard
    As deadlines loom in California's landmark law to curb greenhouse-gas emissions, the Senate hopes to write into the state budget a rule that forces Governor Arnold Schwarzenegger's Market Advisory Committee to eschew closed-door meetings and allow the public to view its deliberations. The committee is charged with proposing the heart of the carbon-emissions law--the system of rewards and penalties that will actually make the statute work. The confidential nature of the committee is well known in the Capitol but has been largely ignored outside the state, where the focus has been as much on Schwarzenegger, an actor-turned-politician with a huge...

    A group of scientists have found a way to bend and direct liquid using only the force of light, according to a study that will be published Friday. The French and American physicists used a laser beam to produce a surprisingly long and steady jet of soapy liquid that was narrower than a human hair. When directed at a different angle, it pushed the liquid into a hump-like shape. It is believed to be the first time a laser had been used to generate bulk flow in fluids. The discovery could lead to advances in biomedical and biotechnological research by...
  • Light is made of particles AND waves, not OR

    Work completed by physics professors at Rowan University shows that light is made of particles and waves, a finding that refutes a common belief held for about 80 years. Shahriar S. Afshar, the visiting professor who is currently at Boston's Institute for Radiation-Induced Mass Studies (IRIMS), led a team, including Rowan physics professors Drs. Eduardo Flores and Ernst Knoesel and student Keith McDonald, that proved Afshar’s original claims, which were based on a series of experiments he had conducted several years ago. An article on the work titled "Paradox in Wave-Particle Duality" recently published in Foundations of Physics, a prestigious,...

    Alien Light: Taking the spectra of extrasolar planets Ron Cowen Astronomers have for the first time recorded the spectra of light emitted by two extrasolar planets. This achievement provides a new, direct way to analyze the atmosphere of alien worlds light-years from Earth. OBSCURED ORB. Clouds may sheathe the atmosphere of some extrasolar planets, masking the presence of water vapor at lower altitudes, as in this artist's depiction. JPL-Caltech/NASA Obtained by NASA's Spitzer Space Telescope, the infrared spectra represent a milestone in the study of distant planets, says David Charbonneau of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass. Both...

    A bionic eye implant that could help restore the sight of millions of blind people could be available to patients within two years. US researchers have been given the go-ahead to implant the prototype device in 50 to 75 patients. The Argus II system uses a spectacle-mounted camera to feed visual information to electrodes in the eye. Patients who tested less-advanced versions of the retinal implant were able to see light, shapes and movement. "What we are trying to do is take real-time images from a camera and convert them into tiny electrical pulses that would jump-start the otherwise...

    Long-lasting near-infrared LEDs could be used to make cheap, flexible night-vision displays and sensors.Universal Display Corporation’s phosphorescent organic LED display can be built on a flexible plastic substrate. The company, working with researchers at the University of Southern California and Princeton University, has now made near-infrared emitting LEDs and plans to make a near-infrared version of the flexible display. The display would be invisible to the naked eye but visible through night-vision goggles for covert military operations.

    White beetle dazzles scientists The researchers looked at the beetle close up A dazzling insect could help the development of brilliant white, ultra-thin materials, a study suggests.The finger-tip sized Cyphochilus beetle, found in south-east Asia, had a shell whiter than most other materials found in nature, UK researchers said. Close inspection reveals a unique surface structure covered with scales 10 times thinner than human hair. A report in Science magazine claims mimicking these scales could provide a range of applications for industry. When I put them under the electron microscope, it was like another world had opened up Dr...

    New Solar Cell Breaks the “40 Percent Efficient” Sunlight-to-Electricity Barrier WASHINGTON, DC – U.S. Department of Energy (DOE) Assistant Secretary for Energy Efficiency and Renewable Energy Alexander Karsner today announced that with DOE funding, a concentrator solar cell produced by Boeing-Spectrolab has recently achieved a world-record conversion efficiency of 40.7 percent, establishing a new milestone in sunlight-to-electricity performance. This breakthrough may lead to systems with an installation cost of only $3 per watt, producing electricity at a cost of 8-10 cents per kilowatt/hour, making solar electricity a more cost-competitive and integral part of our nation’s energy mix. “Reaching this milestone...

    At dusk on Monday, the fifth anniversary of the Sept. 11 terrorist attacks, residents across the Tucson valley will be able to look up and see two pillars of light streaking toward the sky from "A" Mountain. The beams of light that will flank the red, white and blue "A" on the mountain are intended to mimic the "Tribute in Light" that occurs annually on Sept. 11 in Lower Manhattan. It was all supposed to be a secret until Monday night. "Our original goal was to turn on the lights and not tell anyone," said Tucson developer Jim Campbell, who...
