Philips LED Light Bulb Lasts 25 Years, Costs $60

The good news: Philips has launched a brand new light bulb designed to last for 20 years or more and save hundreds of dollars in electricity charges before needing replacement. The bad news: The bulb carries a retail price tag of $60. The new ... Philips bulb is a prime example of alternative energy-saving technology that wallops the inefficiency of today's conventional but popular devices. The reason: Traditional light bulbs work by heating a thin metal filament inside a glass bulb. While this produces light from the glowing filament, it also wastes a lot of the energy. In fact, conservationists ... (view more)

Time Travel 'Impossible,' Scientists Say

From Family Matters to The Simpsons and, of course, Back to the Future, the idea of time travel has become a common theme in American pop culture. There's no doubt, then, that many will be disappointed to hear of a new report from a group of Hong ... Kong scientists which suggests that traveling through time is simply impossible. The report comes from the Hong Kong University of Science and Technology, where researchers under the direction of Professor Shengwang Du have concluded that single photons (the absolute smallest particle of light) simply can't travel faster than light. The finding is ... (view more)

Or how the piercing sunset on the drive home makes you want to drill into the side of your skull in some vain attempt to relieve the pressure? Then take note ... of a recent study by Boston-based researchers who say they can now verify that light affects migraine headaches. In a report published Sunday through Nature Neuroscience, Boston researchers have found that certain cells in the brain, referred to as the thalamus, can sometimes act as a sort-of battleground for information based on the brain's visual ... (view more)

University's 'Metamaterials' Cloak 3-D Objects

They're the stuff of Disney fantasy and childhood dreams, but invisibility cloaks are something University of California scientists stay they are one step closer to developing. The scientists at the Nanoscale Science and Engineering Center, lead by ... Xiang Zhang, are creeping closer to perfecting 'metamaterials', artificially engineered structures that have properties not seen in nature, such as negative refractive index. These metamaterials have recently undergone successful tests allowing scientists to cloak 3-D objects. The technology works when the metamaterials scatter the light that ... (view more)

Light Bulb Went Out? Print A New One!

After acknowledging the recent surge in popularity of O.L.E.D. technology and experimenting with several new ideas, General Electric has stumbled onto something that (if successful) will undoubtedly become the way future generations light their ... rooms. In recent weeks, the company has run numerous tests using a 'roll-to-roll' process to print out continuous organic light-emitting diodes (O.L.E.D.s) at a fraction of the current cost. Basically, the company has found a way to literally print off a set of miniature working lights from a printing press. All experiments performed thus far were ... (view more)
