Light seems to defy its own speed limit

It's a speed record that is supposed to be impossible to break. Yet two physicists are now claiming they have propelled photons faster than the speed of light. This would be in direct violation of Einstein's special theory of relativity, which states that nothing, under any circumstance, can exceed the speed of light. Researchers from the University of Koblenz, German, say they have tunnelled photons "instantaneously" across a barrier of various sizes up to a meter wide.

1. Matter flashed at ultra speed
   06-12-2007 · EurekAlert!
   Using a robotic telescope at the ESO La Silla Observatory, astronomers have for the first time measured the velocity of the explosions known as gamma-ray bursts. The material is travelling at the extraordinary speed of more than 99.999 percent of the velocity of light, the maximum speed limit in the universe.

2. Scientists see DNA get 'sunburned' for the first time
   02-01-2007 · EurekAlert!
   For the first time, scientists have observed DNA being damaged by ultraviolet (UV) light. Chemists used a special technique to watch strands of DNA in the laboratory sustain damage in real time. They observed the most common chemical reaction among a family of reactions on the DNA molecule that are linked to sunburn, and discovered that this key reaction happens with astounding speed.

3. MU physicist defends Einstein's theory and 'speed of gravity' measurement
   10-03-2007 · EurekAlert!
   Scientists have attempted to disprove Albert Einstein's theory of general relativity for the better part of a century. After testing and confirming Einstein's prediction in 2002 that gravity moves at the speed of light, a professor at the University of Missouri-Columbia has spent the past five years defending the result, as well as his own innovative techniques for measuring the speed of propagation of the tiny ripples of space-time known as gravitational waves.

4. Novel semiconductor structure bends light 'wrong' way -- the right direction for many applications
   10-14-2007 · EurekAlert!
   A Princeton-led research team has created an easy-to-produce material from the stuff of computer chips that has the rare ability to bend light in the opposite direction from all naturally occurring materials. This startling property may contribute to significant advances in many areas, including high-speed communications, medical diagnostics and detection of terrorist threats.

9. Evolution of genomic imprinting
   09-06-2007 · EurekAlert!
   How we come to express the genes of one parent over the other is now better understood and it doesn't seem to have originated in association with sex chromosomes. New research published in the online open access journal, BMC Evolutionary Biology, has shed light on the evolution of genomic imprinting, in which specific genes on chromosomes that have been inherited from one parent are expressed in an organism, while the same genes on the chromosome inherited from the other parent are repressed.

10. Racing Ahead at the Speed of Light
    02-06-2008 · Brookhaven National Laboratory
    Imagine trying to catch up to something moving close to the speed of light - the fastest anything can move - and sending ahead information in time to make mid-path flight corrections. Impossible? Not quite. Physicists at the Relativistic Heavy Ion Collider (RHIC), a particle accelerator at Brookhaven Lab, have achieved this tricky task - and the results may save the Lab money and time in their quest to understand the inner workings of the early universe.
