*CARBON AND ITS MANY DIMENSIONS. A Close Inspection of NanoCarbon Tubes
Houston - September 30, 1999 - Fullerene fibers, virtually too small to be seen but with huge prospects for material science, will be showcased along with other technologies at NASA's Inspection99 at Johnson Space Center Nov 3-5

*Novel Neural Net Recognizes Spoken Words Better Than Human Listeners
Machine demonstrates superhuman speech recognition abilities. University of Southern California biomedical engineers have created the world's first machine system that can recognize spoken words better than humans can. A fundamental rethinking of a long-underperforming computer architecture led to their achievement.

*3D circuits -- changing the shape of things to come. A new technology that
allows 3-D electronic circuits to be moulded into plastic objects is set to change the shape of tomorrow’s technology by allowing designers much greater freedom and providing excellent weight and space savings. The technology, being developed by Interconnection and Electronics Chemicals in the UK, can be used to produce products that can be assembled with lower production costs than using traditional technologies and are 100 per cent recyclable. http://www.eurekalert.org/releases/iom-3dc092499.html

*Scientists Build Bridge Toward 'Thinking' Robots. It's not exactly the
Golden Gate -- just a 6 1/2 foot (2 meter) span made of children's Lego blocks -- but the bridge designed by a computer at Brandeis University could be a step toward the creation of intelligent robots, researchers said Friday.

*CIA invests in Silicon Valley. The US spy agency is to invest $28m in a

*Photons on Demand. 1 October 1999. Laser physicists are good at producing
and manipulating single photons, but as with good comedy, the timing is important. Even the best experiments in quantum cryptography and computing--applications that make use of single photon properties--use sources that emit photons at random times. In the 4 October PRL a French team demonstrates a system that emits single photons on a dependable schedule at a frequency of 3 MHz. One other "triggered" photon source which operates on completely different principles was reported earlier this year. http://focus.aps.org/v4/st17.html

*A Clinton administration proposal to build a civilian research facility
just off the northern coast of Long Island for countering biological terrorism has local residents worried they’ll one day be living in the path of a deadly microbe.

*Experimental gene therapy proves deadly. An 18-year-old Arizona man with a
rare metabolic disease has died while participating in a gene-therapy experiment, marking the first death attributed by doctors to a burgeoning field of research that seeks to cure people by giving them new genes. http://www7.mercurycenter.com/premium/nation/docs/gene29.htm

*Do Diamonds Hail Down Upon Neptune And Uranus?
If experiments at the University of California, Berkeley, are any indication, future explorers of our solar system may well find diamonds hailing down through the atmospheres of Neptune and Uranus. These planets contain a high proportion of methane, which UC Berkeley researchers have now shown can turn into diamond at the high temperatures and pressures found inside these planets.

*Chandra Discovers X-ray Ring Around Cosmic Powerhouse in Crab Nebula. After
barely two months in space, NASA’s Chandra X-ray Observatory has taken a stunning image of the Crab Nebula, the spectacular remains of a stellar explosion, and has revealed something never seen before: a brilliant ring around the nebula’s heart.

*First Brain Cancer Surgeries Using New Space-Age Probe Are Successful

has endorsed an overhaul of Australia's medical and health research framework, including plans to increase pay for senior scientists to arrest the overseas "brain drain". (Financial Review) http://www.afr.com.au/content/991002/news/news4.html

*French scientists have identified a gene associated with the kind of brain
seizure that killed Olympic sprinter Florence Griffith Joyner. Faulty copies of the gene, known as CCM1, are responsible for the development of tangled blood vessels in the brain known as cavernous angiomas, according to a study by three laboratories in Paris.

*Nanorover to Help Fetch Asteroid Material (Space.com)With advances in
technology and experience from the Sojourner, the new rover has better optics and computing power than the Mars rover. The rover has four wheels and a rocker suspension similar to Sojourner. http://www.space.com/news/planetarymissions/nanorover_990929.html

*Sniffing DNA may relieve asthma

The Independent - LondonMILLIONS OF asthma sufferers could soon be using inhalers filled with DNA from bacteria to relieve their symptoms, according to a team of American scientists who have tested the system on mice. Such inhalers could be ready within five years if the research proves effective in humans. Mice that had been treated to give them asthma-like attacks developed far less severe symptoms after inhaling DNA from bacteria. Most present treatments for asthma focus on reducing the inflammation of the bronchial tubes, which become affected in an immune response whose cause is still unclear. A potential vaccine is undergoing trials at a London hospital. Now, a new treatment for sufferers is proposed by a team at the University of Iowa. Dr Joel Kline, a lung expert at the university, told New Scientist magazine that the body was programmed from birth to recognise the DNA of invasive bacteria and some viruses. He explained: "Your body can't wait weeks for a specific antibody to be produced to begin attacking." Early exposure to bacteria, and stimulation of an antibody response is thought to stop people developing asthma later in life. Dr Kline's work aims to prompt the response by using bacterial DNA. An experiment with mice, sensitised to develop asthmatic symptoms when they encountered a protein from eggs, showed that sniffing short sections of DNA from bacteria, mixed with the protein, did not lead to symptoms. Dr Kline also found that the number of white blood cells entering the lungs and causing inflammation fell to 10 per cent of previous levels.

*Police have opened China's first DNA data bank in Shanghai, storing blood
samples of 2,500 criminals, the state-run Xinhua News Agency said Thursday. The Justice Ministry plans a nationwide network of such centers meant to help catch criminals through blood or hair evidence, Shen Weizhong, director of the ministry's Judicial Authentication Research Institute, was quoted as saying. Similar centers already exist in the United States and Britain.
