| GOODBYE INTERNET GRIDLOCK |
| IMAGINE an internet connection so fast it will let you download a whole movie in just 5 seconds, or access TV-quality video servers in real time. That's the promise from a team at the California Institute of Technology in Pasadena, who have developed a system called Fast TCP. A key feature of Fast TCP is that it could run on the same internet infrastructure we have today. |

| SPIDERS WEAVE A WEB OF LIGHT |
| WHAT do you get if you give a delicate thread of spider's silk a glassy coating- and then extract the silk by baking? Yushan Yan reckons you will solve a major problem in photonics: how to make ultra-thin, hollow optical fibres narrow enough to carry light beams around the fastest nanoscale optical circuits. Using this technique, Yan and a team of engineers from the University of California at Riverside say they soon expect to be able to make hollow fibres with cores just 2 nanometres wide- or 50,000 times thinner than a human hair. |

| NEW TECHNIQUE TRANSMITS DATA AT 2.8 GIGABITS PER SECOND |
| A test conducted by two Chicago computer scientists to push trans-Atlantic high-speed data transmission has resulted in a new top speed of 2.8 gigabits (billion bits) per second. |
|
| HIDING IN THE NOISE AND CHAOS |
| A new and novel way of communicating over fiber optics is being developed by physicists supported by the Office of Naval Research. Rather than using the amplitude and frequency of electromagnetic waves, they're using the polarization of the wave to carry the signal. Such a method offers a novel and elegant method of secure communication over fiber optic lines. |
|
| THE NEXT GENERATION OF COMPUTERS WILL BE TIMELESS |
| Time is running out for the clocks that make our computers tick. Scientists have developed a new generation of hardware and software based on the simpler designs of the 1950s. |
|
| NANOWIRE-BASED ELECTRONICS AND OPTICS COMES ONE STEP CLOSER |
| An entirely new generation of powerful ultra-small computers and electronic devices is one step closer, according to researchers at the University of California-Berkeley. Their work, and that of a Swedish team, is reported in the February issue of the peer-reviewed journal Nano Letters, published by the American Chemical Society, the world’s largest scientific society. |

| WHAT'S THE DATE? |
| Edward M. Reingold, chairman of the Department of Computer Science at Illinois Institute of Technology in Chicago, and Nachum Dershowitz, professor of computer science at Tel Aviv University, have recently put out their second edition of Calendrical Calculations (Cambridge University Press, 2001). |

| DEVICE COULD MAKE FOR FASTER INTERNET, BETTER TELECOMMUNICATIONS |
| Whether you're waiting for a computer to download the latest movie trailer, or just holding for a long-distance phone call to connect, you may one day get faster service as the result of a new device invented by Ohio State University engineers. |

| OPTIC FIBRE PROVIDES VAST CAPACITY FOR TRANSMITTING INFORMATION BUT IT'S NOT UNLIMITED |
| Researchers have established the theoretical limit to the information-carrying capacity of optic fibres. In the insatiable quest for greater "bandwidth", the finding is important. |
|
| THREE MAJOR LABS JOIN FORCES TO DEVELOP FASTER SEMICONDUCTORS |
| Scientists at Oak Ridge National Laboratory (ORNL), Motorola Labs, and Pacific Northwest National Laboratory (PNNL) have entered a cooperative research and development agreement (CRADA) aimed at increasing the speed of future generations of integrated circuits. |

| QUANTUM JUMP IN THE INTERNET PROTECTION |
| Single photons moving via an fiber-optic cable are the most advanced and rapid way of transferring information. But fiber optics brings in new challenges. Hackers can obviously use cluster dividers to deflect indicator flows and get access to confidential information without a risk of being identified. However, if not a cluster, but a single photon, the smallest discrete light energy source called "quantum", carries information, it will be easier to recognize a system invader. |
|
| HACKERS ARE LEARNING TO CARRY OUT THE INTERNET WARS |
| Computers of Western countries connected to the Internet network are likely to become the target which will be most frequently hit by these countries' enemies. Secret services of all countries are getting interested in the advanced communication technologies; armies of all countries are forming divisions consisted of soldiers-hackers. That was the information presented by the BND's president at the Information Wars symposium held in Munich. |
