| Scientists Develop the Perfect Wrap A new kind of carbon provides a new kind of enclosure Airtight containers are not always so airtight. As any child will discover the day after a birthday party, even a tightly tied helium balloon will leak out its gas over the course of many hours. Now scientists have come up with a supremely efficient barrier that lets nothing in or out. |

| The Interplanetary Internet
NASA has successfully tested the first deep space communications network modeled on the Internet. Working as part of a NASA-wide team, engineers from NASA's Jet Propulsion Laboratory in Pasadena, Calif., used software called Disruption-Tolerant Networking, or DTN, to transmit dozens of...  |

| 'Digital Dark Age' may doom some data
What stands a better chance of surviving 50 years from now, a framed photograph or a 10-megabyte digital photo file on your computer's hard drive?
The framed photograph will inevitably fade and yellow over time, but the digital photo file may be unreadable to future computers - an...  |

| Denser computer chips possible with plasmonic lenses
Engineers at the University of California, Berkeley, are reporting a new way of creating computer chips that could revitalize optical lithography, a patterning technique that dominates modern integrated circuits manufacturing.
By combining metal lenses that focus light through the...  |

| New Solar Energy Material
Researchers have created a new material that overcomes two of the major obstacles to solar power: it absorbs all the energy contained in sunlight, and generates electrons in a way that makes them easier to capture.
Ohio State University chemists and their colleagues combined...  |

| Artificial Cells Could Power Medical Implants
Researchers at Yale University have created a blueprint for artificial cells that are more powerful and efficient than the natural cells they mimic and could one day be used to power tiny medical implants.
The scientists began with the question of whether an artificial version of...  |

| The Day the World Didn't End
Here's what didn't happen on September 10th:
The world did not end. Switching on the world's largest and most powerful particle accelerator near Geneva, Switzerland, did not trigger the creation of a microscopic black hole. And that black hole did not start rapidly sucking in...  |

| Hack-a-vote: Students learn how vulnerable electronic voting really is
This week undergraduate and graduate students in an advanced computer security course at Rice University in Houston are learning hands-on just how easy it is to wreak havoc on computer software used in today's voting machines.
As part of his advanced computer science class, Rice...  |

| Space tech helps to reach long-jump world record
German athlete Wojtek Czyz, running with a space-tech enhanced prosthetic leg, set a new world record at the Paralympics 2008 in Beijing, reaching an amazing 6.50 m and beating the previous world record by 27 cm.
In spring 2004, ESA’s Technology Transfer Programme (TTP) technology...  |

| MIT paves the way for "artificial noses"
MIT biological engineers have found a way to mass-produce smell receptors in the laboratory, an advance that paves the way for "artificial noses" to be created and used in a variety of settings.
The work could also allow scientists to unlock the mystery of how the sense of smell can...  |

| The twins example of the special theory of relativity
I have a question concerning the story of the twins where one stays on earth and the other travels in space ship through space at nearly the speed of light. When the twin on the space ship returns to earth he would be younger than his twin who stayed on earth since traveling at near the speed...  |

| The COLLAPSE of SR (Special relativity)
The collapse of Special Relativity
I study upon light kinematics and I have some new results/methods for space-time. One of them menaces the SR seriously.
I have followed forums about special relativity. I am glad for finding some objectors. My determination will approve...  |

| Boston physicists celebrate first beam for Large Hadron Collider Boston area universities collaborate on the greatest physics experiment of all time Scientists today sent the first beam of protons zooming at nearly the speed of light around the 17-mile Large Hadron Collider. The LHC, located at the CERN laboratory near Geneva, Switzerland, is the world's most powerful particle accelerator. |

| relativity and chaos
This idea came to me this weekend. I was trying to figure out how statistics fits into Einstein's claim that the laws of physics are the same in all reference. If we have time dilation within a moving reference, does that mean that the frequency of chaos will get less relative to a...  |

Here is an interesting physics affect. It has to do why gold is yellow in color. Most metals are silvery color because the delocalized electrons in the metal absorb and emit a wide range of frequencies. Gold is unique in that although it does essentially the same thing, its delocalized...  |
