*FEED magazine has an article on nanotechnology. "Thinking Small." Mark
Pesce (co-inventor of VRML) on molecular-scale manufacturing, the gray goo problem, and how nanotechnology will change the world as we know it. http://www.feedmag.com/invent/pesce.html?alert
*Ultra-tiny machines are becoming big hope for scientists. After years of
preliminary research, hope and hype, business and industry are starting to enter the strange, invisible world of the very ... Very ... VERY small.Government agencies, leading universities and major corporations are rapidly expanding their efforts to design and build machines and structures on the scale of atoms and molecules. This exploding new discipline -- known as ``nanotechnology'' -- has become a top scientific priority in Congress and at the White House.
*Plastic Pillars of the Microworld. Rome wasn't built in a day, but a
nanosized version of it may be thrown up that quickly in the near future. At the International Symposium on Cluster and Nanostructure Interfaces here last week, researchers described a new technique capable of creating arrays of plastic pillars, each less than a micrometer across, that resemble nothing so much as tiny versions of the great columns of Rome's coliseum. http://www.academicpress.com/inscight/11041999/graphb.htm
*It's a small, kinky world. Tiny, bent tubes of carbon might be used both to
wire up and to construct DNA-scale electrical devices. http://helix.nature.com/nsu/991118/991118-1.html
*Yale Research Team First to Describe Molecular-Sized Memory -- Discovery
has Implications for Drastically Reducing Cost of Computer Memory. omputer storage capacity can be vastly increased using a molecular memory based on a single molecule, a research team from Yale and Rice Universities has discovered.
*A miniaturized triode could instead replace the transistor as the switch of
information technologies. Driskill-Smith and colleagues have now fabricated a ‘nanotriode’ tube measuring less than 100 nanometres (millionths of a millimetre) in any direction.
*Making Robots Microscopic but Mighty. Michael J. Marsella is dreaming small
these days. The assistant professor of chemistry at UC Riverside is trying to create artificial "muscles" no bigger than a single molecule. http://www.latimes.com/news/science/science/19991108/t000101547.html
*Chemical researchers build molecular computer. A molecular electronics
research project at Mitre Corp. has achieved a milestone in the effort to build self-assembled molecular computers. Researchers James Ellenbogen and Christopher Love have invented chemical building blocks that support the operation of a digital half adder, which represents a new level of circuit complexity for the field.
*How Biological Molecules Move Electrons: Simplicity Trumps Complexity. In a
sweeping new study, researchers at the University of Pennsylvania Medical Center have shown that the natural engineering principles governing electron transfer within proteins are significantly less complex than has been the prevailing view.
*Crack open an egg and cure a disease. Two American companies are planning a
pilot test of drugs in eggs laid by genetically engineered chickens. The birds carry genes that make their eggs contain proteins that can treat disease. These proteins are then passed on to future generations of chickens without the need to repeat the injection. http://www.newscientist.co.uk/ns/19991113/newsstory5.html
*Improved biodegradable hydrogels. Two novel biodegradable hydrogels
developed by a Cornell University fiber scientists have potential applications for controlling and delivering many kinds of medications inside and outside the body, for anchoring biological substances such as skin and vascular tissues and may even be used to introduce viruses to the body for gene therapy.
*UNC-CH Physicists Find Atoms Of Chilled Metallic Liquids Chiefly Move In
CHAPEL HILL - For the first time, atomic-scale measurements have revealed that atoms in a metallic liquid cooled significantly below the melting point - also known as a super-cooled liquid -- chiefly move together in clustered lockstep.
*Lawmakers seek special labeling for genetically engineered food. Everybody
who eats food made in America deserves to know what's in it, a bipartisan group of lawmakers said as they offered legislation to create special food labels.
*Novel neurotransmitter overturns laws of biology, offers potential for
stroke treatment. Johns Hopkins scientists have identified a new and unusual nerve transmitter in the brain, one that overturns certain long-cherished laws about how nerve cells behave.
*Memory uses separate information pathways. The memory has separate pathways
for different types of information. This has been demonstrated by means of anatomical and electrical measurements of the hippocampus and the adjacent cerebral cortex of laboratory rats. The signal pathways ultimately meet in the so-called subiculum of the brain, from which information from the hippocampus is passed on to other areas of the brain. http://www.eurekalert.org/releases/nwon-mus110999.html
*The Nov 8-22 issue of OakRidge National Laboratory Newsroom is online:
(includes- Spinach and chips, New tool for archaeologists, 10 billion for dinner, New smart surfaces, and Reigning in uranium.) http://www.ornl.gov/Press_Releases/StoryTips/storynov99.htm Also the DOE Pulse for November: (PDF or HTML) http://www.ornl.gov/news/pulse/
*Cheap energy - a revolutionary new way. Australian scientists have
perfected a new-age combustion technology, which is poised to clean up greenhouse gas emissions, slash energy costs and significantly boost productivity."We have produced a new generation pulse combustion technology which until now has defied the best efforts in the world to turn it into a practical option for everyday use,"
*Optic fibre world records broken.Bell Laboratories believe they have broken
two world records in the use of optical fibres to transmit information. http://news.bbc.co.uk/hi/english/sci/tech/newsid_517000/517733.stm
*Gene Skews Inheritance Patterns. Mouse geneticists have known for decades
that, contrary to the laws of Mendelian genetics, one member of certain chromosome pairs may be passed to the next generation more often than the other member. Now scientists have fingered the gene responsible for giving some mouse chromosomes their advantage.
*Great minds share millennial visions. Thirty great minds offer their
visions for the 21st century in a new book titled “Predictions. http://www.msnbc.com/news/331095.asp
*Irish Times Opinion. "Unseen power of simple microbe." The most common
image evoked by the term micro-organism(microbe) is likely to be that of "germs", i.e. disease-causing microbes. Some micro-organisms do cause human disease but to think of this entire class of biological organisms in this manner is to grossly underestimate its importance and role. http://www.ireland.com/newspaper/science/1999/1108/sci1.htm
*Taking Einstein to the Mat. Project Peers into Black Holes to Test Theory
of Relativity. Scientists gather this week in the piney woods of Louisiana. They will be dedicating the Laser Interferometer Gravitational-Wave Observatory, a $350 million project with a highly ambitious goal: to test Einstein’s theory of relativity.
*Dr. Jill Tarter: Looking to Make 'Contact' (She is the woman the movie
"Contact' based the main character on) A little bit of SETI in here. http://www.space.com/science/astronomy/tarter_profile_991112.html

of light and x-rays, an interdisciplinary group at the University of California, San Diego has directly observed the melting of material without taking the route of a typical melting process they report in the Nov. 12 issue of Science.
*US Army cracked on the Nov. 11th.
The original site is down, but this was what was left behind: http://www.2600.com/hacked_pages/1999/11/www.2rotc.army.mil/ And then the Navy on the first, who now adorns a pop up window of moniter warning:
What was left behind:
*Geneticists find link between ancient gene and the HIV virus.Much like
archeologists who search the fossil record looking for clues about the past, Duke University Medical Center researchers have done their own genetic sifting and have found a striking similarity between viral genetic material that has always existed in humans and HIV, a relatively new virus to infect humans.
Thank you, and havea nanoriffic day!
