[Not a lot of breakthrus since my last post on the 24th]
*Quantum fuel for future computers. Research suggests how software
marketplace might change. Imagine a world where software is computational fuel — churned out by a processing plant and shipped down an optical-fiber pipeline to your computer, where it’s consumed and destroyed. That just might be the model for a future generation of quantum computers, new research suggests. (MSNBC Nov. 25 99)
**Nanovation Technologies in the Toronto Star. Shedding light on the
THE UBIQUITOUS computer chip, based on silicon, has radically changed the world in which we live. But as silicon approaches its physical limits in miniaturization and speed, we are moving into a new world, based on the properties of light, the world of photonics, which will herald the next $1 trillion industry.
*In this weeks issue (Nov 22, 99) There is an article "CARBON-BASED DEVICES:
Organic molecule acts as reversible switch, while nanotube kink controls current flow."
You can go to the url, but need a password and ID. Or look in your paper subscription.
http://pubs.acs.org/cgi-bin/cenmaster.cgi?contents There was also a small article in last weeks issue of C&E news (Nov 15, 99 volume 77, #46)
NANOSCALE DODECAHEDRON: Self-assembly produces largest-ever nonbiological supramolecular complex. Same applies as with previous for url: http://pubs.acs.org/cgi-bin/cenmaster.cgi?back
*Muscle machine 'to build super-athletes'. A muscle-generating machine could
enable athletes to realise their maximum potential and help arthritis sufferers combat disability, say its inventors. The device, developed by UK scientists, uses electrical signals to generate deep layers of muscle. (Nov. 24 99 BBC) http://news.bbc.co.uk/hi/english/health/newsid_533000/533359.stm
*Japan eyes wearable PC. Those tired of hauling around "portable" computers
may be able to wear a Pentium PC from next year. On Friday, Japanese camera-maker Olympus and IBM Japan revealed a prototype of a wearable PC. (BBC Nov 26 99)
*The World Changers ‘TR 100’ Pegs Young Innovators. Nov. 25 — To celebrate
its 100th anniversary, the MIT Technology Review, the oldest journal of science and technology in the United States, has selected the TR 100 — 100 innovative technologists and scientists under the age of 35. Profiles of selected members of the TR 100 will appear on ABCNEWS.com through Jan. 1, 2000. Here is this week’s installment.
*Or is Time Merely an Illusion? (The Edge on Nov, 25 99) Speculation about
the nature of time has long been the domain of philosphers: Physicists dared not approach. Physicist Julian Barber suggests that time is an artifact of the arrangement of matter. (long interview) http://www.edge.org/3rd_culture/barbour/barbour_index.html
*Turkey Day, Silicon Style. High-Tech Startup Will Be Buzzing This Weekend.
In San Francisco’s up-and-coming SoMa district, a group of engineers and developers are huddled together this Thanksgiving in a second-floor loft, working feverishly on a new project. And believe it or not, they’re pretty thankful. Backflip.com, formerly known as the iTixs Project, is a “secret” startup founded by a pair of Netscape Communications alumni. http://abcnews.go.com/sections/tech/DailyNews/siliconturkey991125.html
*A Crystal with a Twist ( 24 Nov.99 PRF)
Doubly twisted. PET(R*)-9 is the first polymer crystal with twists along two different axes, although only one of them is visible in this image. The needle-like particles are not part of the polymer but were used to find the polymer's orientation within the crystal. As in the famous line from the 1967 movie "The Graduate," the importance of polymers in modern life can be expressed in one word: plastics. To develop new polymer-based materials for the future, researchers want to understand and manipulate polymer structures at the molecular level.
*Science: Story of the century. Science dominates the century's top 100 news
stories, according a poll of US journalists. Of the top 100 stories in the survey conducted by the "Newseum", an American Online exhibition of news journalism, 38 are science related. (Nov 26, 99 BBC) http://news.bbc.co.uk/hi/english/sci/tech/newsid_534000/534983.stm
*It's heresy, but time running backwards could explain dark matter. The
universe may contain regions where milk would stir itself out of coffee and eggs would un-break, according to a physicist in New York state. The idea that there may be regions where time runs backwards could explain invisible dark matter. This kind of matter, invoked by cosmologists to explain the movement of galaxies, could originate in a future contracting phase of the Universe. (New scienctist Nov 27, 99)
*It's likely that quantum computing will, in the future, be a
reality.However, making algorithms for them is not going to be trivial as they don't function at all like our traditional digital computers. To facilitate this, Open Qubit wants to emulate them. The emulator won't run at nearly the speed of a real quantum computer, but it should at least be helpful for developing algorithms before we finish developing the computers. (I read an interesting article about this in the current issue of 2600) http://www.openqubit.org/
*In the last Nanogirl news I mentioned an article in Feed magaine about
nanotechnology called "Thinking Small". It seems MSNBC has some link to the magazines authors and has a site up called Beyond Possibility: The Dream Machines, with an article of their own, a list of 21st century inventions and backlinks to Feed coverage. (Nov 24,99) http://msnbc.com/news/338770.asp#BODY
*Molecule Identified That Blocks Nerve Reconnection. Nerve tissue
transplants are among the promising experimental therapies to restore communication among cells in injured spinal cords, but scientists long have wondered why the transplanted cells don't grow more vigorously, thereby enhancing the level of recovery. (UniSci Nov 24,99) http://unisci.com/stories/19994/1124994.htm

sight?-covering my eyes. (SMH 27/11/99)London: Scientists at the Institute of Psychiatry in London are trying to show the difference between love and lust by using the latest scanning technology to measure blood flow to the brain.
*Brain cells involved in learning habits. (Deseret News) As rats learned
while running in a maze, there was a change in the firing pattern of certain neurons in the brain — a new pattern that can mark the way habits are acquired, according to a study appearing today in the journal Science.. In the study, Graybiel and colleagues implanted sensors into rats' brains(Nov 26 99)
*Lasers to test role of gravity in birth of universe. New technology to help
determine if Einstein theory is true. Scientists are poised to gain important new insights into black holes, exploding stars and the birth of the universe by studying the very same phenomenon responsible for the soup stain in your lap: gravity. (Detroit news Nov 26, 99) http://detnews.com/1999/nation/9911/26/11260061.htm
*Europe's suspicion leaves U.S. farmers in doubt. Planting of genetically
altered crops burdened with nettlesome drawbacks. Burlington County farmer Larry Durr and retired French physics researcher Jacques Bullot have never met or even heard of each other.They nevertheless are locked in a tug of war over genetically modified food. (San jose Mercury News Nov. 27,99) http://www7.mercurycenter.com/premium/nation/docs/seeds27.htm
*IBM uses quantum states to create software. Adding an interesting wrinkle
to the esoteric field of quantum computing, researchers have found a way to use quantum states to create software applications.IBM Corp. had been experimenting with creating algorithms out of quantum mechanical forces, but a team at the company's Almaden Research Laboratory, working with Microsoft Corp. scientists, has devised a way to create one-use-only software by exploiting quantum states. (EE times 11/24/99) http://www.eetimes.com/story/OEG19991124S0047

*(And this suppose to be a PROBlem?!)Falling into the Web of addiction. For
Arline Tripp, it all started with the death of a close friend. She began staying home alone, spending hour after hour on the computer. She found solace in chat rooms and entertainment on Web sites for her favourite products and TV shows. It seemed harmless enough, but it gradually grew into an obsession. (Nov 25)
Or see the Cyberslacking epidemic article, that suggest recreational surfing on the job is costing money. (Salon Nov 24 99) http://www.salon.com/tech/log/1999/11/24/cyberslacking/index.html
*Scientist offers last minute Y2K quick fix. With time running out before
the dawn of the year 2000, a California company is offering what it calls a quick and easy way to prevent some IBM computers from experiencing Y2K-related problems. Bill Wattenburg, a former Lawrence Livermore National Weapons Laboratory scientist who developed the software, says he has changed the way IBM S/390s and similar computers do math. http://www.cnn.com/TECH/computing/9911/27/y2k.simple.solution/index.html

financial-services companies on the Net, we looked for the category leaders in specific areas such as online banking, brokerage and financial software; for the innovators whose ideas were pushing others to act; and for the big institutions that are defining the environment for everyone. (This article includes a list and links)
*Green glow of success. Genetically-modified insects with eyes that glow in
the dark have been created by German researchers. The ability to produce such bright-eyed creatures could help scientists develop new ways to combat diseases that are spread by insects, such as malaria, and control pests that do damage to crops. (includes picture of fruitfly with green eye) http://news.bbc.co.uk/hi/english/sci/tech/newsid_535000/535240.stm
*Despite international protests, Ukraine restarts Chernobyl. (Gads!) The
Ukrainian authorities Friday restarted the last working nuclear reactor at the Chernobyl power plant, ignoring strong international pressure to shut it down. Reactor No. 3 was restarted at 5:30 a.m. Friday after almost five months of repairs. (Nando Times Nov. 26, 99) http://www.nandotimes.com/noframes/story/0,2107,500061725-500102010-50043710 7-0,00.html
*Apply Quantum Principle with Caution (19 November 1999 PRF)
Cold collisions. This simulation shows atoms in a two-component Bose-Einstein condensate at a temperature near 1 nK, where Bohr's formulation of the correspondence principle fails most dramatically. In the early 20th century physicists realized that classical physics fails to explain atoms, even though it works well for baseballs and planets. Part of the early atomic theory relied on Niels Bohr's correspondence principle, which states that the quantum theory must agree with the classical theory in situations where the classical theory is accurate. http://focus.aps.org/v4/st26.html
*R. Buckminster Fuller on PBS. (also with links, inventions and background
information of Fuller)
You can order the video as well
*New tool for comparative gene studies. A great deal is known about how
model organisms such as fruit flies, nematodes and mice develop. But what about beetles, frogs, and birds? Scientists who study gene function in non-model organisms may get a boost from a new technique developed by Nipam Patel, Ph.D., assistant professor of organismal biology & anatomy and Howard Hughes Investigator at the University of Chicago. http://www.uchospitals.edu/news/baculovirus.html
*Prehistoric Man To Debut on Web. Deep in a cave in southern Italy's
Altamura, a prehistoric man is about to enter the realm of technology and come alive on computer screens. Web surfers will be able to remotely explore the cave, hear its sounds, follow its narrow passages covered by animal bones, and watch the Altamura man entombed in his stalagmites. (Discovery Nov. 27, 99)
*DNA Damage Shatters Dreams of Mammoth Cloning. Fragments of DNA from
mammoths have been recovered and sequenced, but are too damaged to make cloning the long-extinct creatures possible, an international team has reported.
*World's largest scalable Linux testbed created by public-private joint
project. The Chiba City Project, conceived by Argonne's Mathematics and Computer Science Division, will be Argonne's most powerful supercomputer. The project will help advance the use of state-of-the-art Linux clusters based on affordable industry standard components in high-performance computing.
*There is a new NAS Computational Molecular Nanotechnology Group page at
http://www.nas.nasa.gov/Groups/SciTech/nano/index.html Their old site:
*You are cordially invited to match wits with some of the best minds in IBM
Seems some of us can't see a problem without wanting to take a crack at solving it. Does that sound like you? Good. Forge ahead and ponder this month's problem.
